Twice weekly yoga classes plus home practice effective in reducing symptoms of depression

Date: March 3, 2017

Summary:
People who suffer from depression should participate in yoga and deep (coherent) breathing classes at least twice weekly plus practice at home to receive a significant reduction in their symptoms.

People who suffer from depression should participate in yoga and deep (coherent) breathing classes at least twice weekly plus practice at home to receive a significant reduction in their symptoms.

The findings, which appear in the Journal of Alternative and Complementary Medicine, provide preliminary support for the use of yoga-based interventions as an alternative or supplement to pharmacologic treatments for depression.

Major depressive disorder (MDD) is common, recurrent, chronic and disabling. Due in part to its prevalence, depression is globally responsible for more years lost to disability than any other disease. Up to 40 percent of individuals treated with antidepressant medications for MDD do not achieve full remission. This study used lyengar yoga that has an emphasis on detail, precision and alignment in the performance of posture and breath control.

Individuals with MDD were randomized to the high dose group, three 90-minute classes a week along with home practice, or the low dose group, two 90-minute classes a week, plus home practice. Both groups had significant decreases in their depressive symptoms and no significant differences in compliance. Although a greater number of subjects in the high dose group had less depressive symptoms, the researchers believe attending twice weekly classes (plus home practice) may constitute a less burdensome but still effective way to gain the mood benefits from the intervention.

"This study supports the use of a yoga and coherent breathing intervention in major depressive disorder in people who are not on antidepressants and in those who have been on a stable dose of antidepressants and have not achieved a resolution of their symptoms," explained corresponding author Chris Streeter, MD, associate professor of psychiatry and neurology at Boston University School of Medicine and a psychiatrist at Boston Medical Center.

According to Streeter compared with mood altering medications, this intervention has the advantages of avoiding additional drug side effects and drug interactions. "While most pharmacologic treatment for depression target monoamine systems, such as serotonin, dopamine and norepinephrine, this intervention targets the parasympathetic and gamma aminobutyric acid system and provides a new avenue for treatment."

A breathing-based meditation practice known as Sudarshan Kriya yoga helped alleviate severe depression in people who did not fully respond to antidepressant treatments, reports a new study published in the Journal of Clinical Psychiatry from researchers in the Perelman School of Medicine at the University of Pennsylvania. The study bolsters the science behind the use of controlled yogic breathing to help battle depression.

In a randomized, controlled pilot study, led by Anup Sharma, MD, PhD, a Neuropsychiatry research fellow in the department of Psychiatry at Penn, researchers found significant improvement in symptoms of depression and anxiety in medicated patients with major depressive disorder (MDD) who participated in the breathing technique compared to medicated patients who did not partake. After two months, the yoga group cut its mean Hamilton Depression Rating Scale (HDRS) score by several points, while the control group showed no improvements. HDRS is the most widely used clinician-administered depression assessment that scores mood, interest in activities, energy, suicidal thoughts, and feelings of guilt, among other symptoms.

More than half of the 41 million Americans who take antidepressants do not fully respond. Add-on therapies are often prescribed to enhance the effects of the drugs in these patients, but they typically offer limited additional benefits and come with side effects that can curb use, prolonging the depressive episode. What's more, patients who don't fully respond to antidepressants are especially at risk of relapse.

"With such a large portion of patients who do not fully respond to antidepressants, it's important we find new avenues that work best for each person to beat their depression," Sharma said. "Here, we have a promising, lower-cost therapy that could potentially serve as an effective, non-drug approach for patients battling this disease."

The meditation technique, which is practiced in both a group setting and at home, includes a series of sequential, rhythm-specific breathing exercises that bring people into a deep, restful, and meditative state: slow and calm breaths alternated with fast and stimulating breaths.

"Sudarshan Kriya yoga gives people an active method to experience a deep meditative state that's easy to learn and incorporate in diverse settings," Sharma said.

In past studies, the practice has demonstrated a positive response in patients with milder forms of depression, depression due to alcohol dependence, and in patients with MDD; however, there are no clinical studies investigating its use for depression in an outpatient setting. Past studies suggest that yoga and other controlled breathing techniques can potentially adjust the nervous system to reduce stress hormones. Overall, the authors also note, well-designed studies that evaluate the benefits of yoga to treat depression are lacking, despite increased interest in the ancient Indian practice. Millions of Americans participate in some form of yoga every year.

In the study, researchers enrolled 25 patients suffering from MDD who were depressed, despite more than eight weeks of antidepressant medication treatment. The medicated patients were randomized to either the breathing intervention group or the "waitlist" control group for eight weeks. (The waitlist group was offered the yoga intervention after the study). During the first week, participants completed a six-session program, which featured Sudarshan Kriya yoga in addition to yoga postures, sitting meditation, and stress education. For weeks two through eight, participants attended weekly Sudarshan Kriya yoga follow-up sessions and completed a home practice version of the technique.

Patients in the Sudarshan Kriya yoga group showed a significantly greater improvement in HDRS scores compared to patients in the waitlist group. With a mean baseline HDRS score of 22.0 (indicating severe depression at the beginning of the study), the group that completed the breathing technique for the full two months improved scores by 10.27 points on average, compared to the waitlist group, which showed no improvements. Patients in the yoga group also showed significant mean reductions in total scores of the self-reported Beck Depression (15.48 point improvement) and Beck Anxiety Inventories (5.19 point improvement), versus the waitlist control group.

Results of the pilot study suggest the feasibility and promise of Sudarshan Kriya as an add-on intervention for MDD patients who have not responded to antidepressants, the authors wrote. "The next step in this research is to conduct a larger study evaluating how this intervention impacts brain structure and function in patients who have major depression," Sharma said.

Yoga may lessen side effects in men undergoing prostate cancer treatment

More men willing to participate in yoga therapy than expected

Date: November 16, 2015

Source: University of Pennsylvania School of Medicine

Summary:
Men with prostate cancer who are undergoing radiation therapy can benefit from yoga, researchers reported.

Men with prostate cancer who are undergoing radiation therapy can benefit from yoga, researchers at the Perelman School of Medicine at the University of Pennsylvania reported at the Society of Integrative Oncology's 12th International Conference.

The new, first-of-its-kind study, led by Neha Vapiwala, MD, an associate professor in the department of Radiation Oncology at PSOM and Penn's Abramson Cancer Center, found that general quality of life and measurements of side effects often experienced by prostate cancer patients--including fatigue, sexual health, and urinary incontinence--were stable throughout a course of outpatient radiation therapy among the men participating in an intensive yoga program.

"Data have consistently shown declines in these important measures among prostate cancer patients undergoing cancer therapy without any structured fitness interventions, so the stable scores seen with our yoga program are really good news," Vapiwala said.

Cancer-related fatigue differs from everyday-life fatigue, which is usually temporary and can be relieved by rest or sleep. Fatigue that stems from cancer or cancer treatments has been found to lower patients' quality of life even more than pain, and studies have shown that anywhere from 60 to 90 percent of patients receiving radiation therapy report this symptom. Furthermore, erectile dysfunction is reported in 21 to 85 percent of all prostate cancer patients, while urinary incontinence is reported in 24 percent of men with this disease.

The possible explanation for the benefits of yoga seen in the study stems from physiologic data demonstrating its ability to help reduce cancer- as well as treatment- related fatigue and to strengthen pelvic floor muscles and increase blood flow. These latter aspects may in turn improve erectile dysfunction and urinary incontinence, said Vapiwala.

"There may also be a psychosocial benefit that derives from participation in a group fitness activity that incorporates meditation and promotes overall healthiness. And all of this ultimately improves general quality of life," she added.

Other studies have demonstrated beneficial health and quality of life effects from yoga interventions in cancer patients. However, yoga has been predominantly evaluated for breast cancer, and research on its role in alleviating prostate cancer patients' side effects has been lacking, largely due to the perception that men would not be willing to participate in this form of holistic exercise.

National statistics indicate that 72 percent of those who practice yoga are female, and only 18 percent of practitioners are over the age of 55. The median age at diagnosis for cancer of the prostate is 66.

"Despite these figures, we found that a structured yoga intervention in the form of twice-weekly classes is feasible for patients during a six- to nine-week course of outpatient radiotherapy for prostate cancer," said Vapiwala. "Our participation-rate finding alone is important because it is a caution against making assumptions about patients without proper evidence."

Specifically, between May 2013 and June 2014, 68 eligible prostate cancer patients were identified and offered study participation, of which 45 consented (66 percent) to attend twice-weekly yoga classes of 75 minutes each, taught by trained Eischens yoga instructors within the Abramson Cancer Center.

Although 18 (40 percent) of these participants were voluntarily withdrawn early due to unavoidable and unanticipated conflicts between radiation treatment times and the yoga class schedule, the remainder were able to participate and the study's feasibility endpoint was met.

"Eischens yoga incorporates ideas from movement theory and kinesiology and is accessible to all body types and experience levels," said Tali Mazar Ben-Josef, DMD, a certified Eischens yoga instructor and researcher in the Abramson Cancer Center, who will present the results at the SOI meeting.

Most yoga participants reported a sense of well-being at the end of each class, and upon finishing the yoga program and concluding their study involvement, many patients requested and received an at-home practice routine to fit their needs, Ben-Josef said.

The effect of yoga was measured by participants' responses to a series of questions that assess overall quality-of-life, cancer-related fatigue, and prevalence of sexual and erectile dysfunction and urinary incontinence. The researchers chose these variables because they affect so many prostate cancer patients.

Severity of fatigue scores demonstrated significant variability over the time of treatment, with increases by week four as expected, but then improving over the course of treatment. Erectile dysfunction, urinary incontinence, and general quality of life scores demonstrated steady trends.

Currently, the team is randomizing prostate cancer patients to participation vs. no participation in this structured yoga program in order to further characterize the potential benefits of yoga in this population.

This trial represents an expansion of the Abramson Cancer Center's integrative medicine and wellness services that are available to patients and survivors. In addition to yoga, patients can receive training in stress-reduction techniques, meditation, reiki therapy, acupuncture, and massage.

"We offer several ways to enhance quality of life, minimize or reduce side effects of cancer and cancer treatment, and promote healing and recovery," Vapiwala said. "This study represents one of many research projects we are conducting in an effort to pinpoint the best, most effective practices to help patients with these needs."

Nearly 240,000 men are diagnosed with prostate cancer each year in the United States, according to the American Cancer Society, which funded the new study.

The full results from the feasibility study are expected to be published early 2016.

Yoga and chronic pain have opposite effects on brain gray matter

Chronic pain is known to cause brain anatomy changes and impairments, but yoga can be an important tool for preventing or even reversing the effects of chronic pain on the brain, according to a National Institutes of Health (NIH) official speaking at the American Pain Society's annual meeting.

M. Catherine Bushnell, PhD, scientific director, Division of Intramural Research, National Center for Complementary and Integrative Health, NIH, explained in a plenary session address that many chronic pain patients show associated anxiety and depression as well as deficits in cognitive functions. In addition, brain imaging studies in rats and humans have shown alterations in gray matter volume and white matter integrity in the brain caused by the effects of chronic pain.

"Imaging studies in multiple types of chronic pain patients show their brains differ from healthy control subjects," said Bushnell. "Studies of people with depression show they also have reduced gray matter, and this could contribute to the gray matter changes in pain patients who are depressed. Our research shows that gray matter loss is directly related to the pain when we take depression into account," said Bushnell.

Gray matter is brain tissue with numerous cell bodies and is located in the cerebral cortex and subcortical areas. The impact of gray matter loss depends on where it occurs in brain. Decreased gray matter can lead to memory impairment, emotional problems and decreased cognitive functioning.

Bushnell said there is compelling evidence from studies conducted at NIH/NCCIH and other sites that mind-body techniques, such as yoga and meditation, can counteract the brain anatomy affects of chronic pain. "Practicing yoga has the opposite effect on the brain as does chronic pain," said Bushnell.

She said the studies show yoga practitioners have more gray matter than controls in multiple brain regions, including those involved in pain modulation. "Some gray matter increases in yogis correspond to duration of yoga practice, which suggests there is a causative link between yoga and gray matter increases," Bushnell noted.

Assessing the impact of brain anatomy on pain reduction, Bushnell said gray matter changes in the insula or internal structures of the cerebral cortex are most significant for pain tolerance. "Insula gray matter size correlates with pain tolerance, and increases in insula gray matter can result from ongoing yoga practice," said Bushnell.

"Brain anatomy changes may contribute to mood disorders and other affective and cognitive comorbidities of chronic pain. The encouraging news for people with chronic pain is mind-body practices seem to exert a protective effect on brain gray matter that counteracts the neuroanatomical effects of chronic pain," Bushnell added.

Yoga as a potential therapy for cardiovascular disease, metabolic syndrome

Date: December 29, 2014

Source: SAGE Publications

Summary:
The potential for yoga to have an impact on concrete, physiological outcomes that represent some of the greatest health burdens today has been demonstrated through new research

Cardiovascular disease (CVD) and metabolic syndrome are major public health problems in the USA and worldwide.

There is promising evidence of Yoga, a popular mind-body practice, on improving cardio-metabolic health.

This review helps strengthen the evidence base for yoga as a potentially effective therapy for such conditions. The results support earlier reviews on the positive benefits of yoga for CVD prevention.

The review demonstrates the potential of yoga to have an impact on concrete, physiological outcomes that represent some of the greatest health burdens today.

Yoga has potential to reduce risk factors of cardiovascular disease

Date: December 15, 2014


Source: European Society of Cardiology

Summary:
Following a systematic review of 37 randomized controlled trials, investigators from the Netherlands and USA have found that yoga may provide the same benefits in risk factor reduction as such traditional physical activities as biking or brisk walking. Yoga, an ancient mind-body practice which originated in India and incorporates physical, mental, and spiritual elements, has been shown in several studies to be effective in improving cardiovascular risk factors, with reduction in the risk of heart attacks and strokes.

There is "promising evidence" that the popular mind-body practice of yoga is beneficial in managing and improving the risk factors associated with cardiovascular disease and is a "potentially effective therapy" for cardiovascular health.

Indeed, following a systematic review of 37 randomised controlled trials (which included 2768 subjects), investigators from the Netherlands and USA have found that yoga may provide the same benefits in risk factor reduction as such traditional physical activities as biking or brisk walking. "This finding is significant," they note, "as individuals who cannot or prefer not to perform traditional aerobic exercise might still achieve similar benefits in [cardiovascular] risk reduction." Their study is published today in the European Journal of Preventive Cardiology.

Yoga, an ancient mind-body practice which originated in India and incorporates physical, mental, and spiritual elements, has been shown in several studies to be effective in improving cardiovascular risk factors, with reduction in the risk of heart attacks and strokes. This meta-analysis was performed, say the investigators, to appraise the evidence and provide a realistic pooled estimate of yoga's effectiveness when measured against exercise and no exercise.

Results showed first that risk factors for cardiovascular disease improved more in those doing yoga than in those doing no exercise, and second, that yoga had an effect on these risks comparable to exercise.

When compared to no exercise, yoga was associated with significant improvement in each of the primary outcome risk factors measured: body mass index was reduced by 0.77 kg/m2 (measured as a "mean difference"), systolic blood pressure reduced by.21 mm Hg, low-density (bad) lipoprotein cholesterol reduced by 12.14 mg/dl, and high-density (good) lipoprotein cholesterol increased by 3.20 mg/dl. There were also significant changes seen in secondary endpoints -- body weight fell by 2.32 kg, diastolic blood pressure by 4.9 mm Hg, total cholesterol by 18.48 mg/dl, and heart rate by.27 beats/min. However, no improvements were found in parameters of diabetes (fasting blood glucose and glycosylated hemoglobin).

Risk factor improvements (in BMI, blood pressure, lipid levels) were significant when yoga was used in addition to medication. Among patients with existing coronary heart disease, yoga provided a statistically significant benefit in lowering LDL cholesterol when added to medication (statins and lipid-lowering drugs).

In comparisons with exercise itself, yoga was found to have comparable effects on risk factors as aerobic exercise. The investigators note that this might be because of yoga's impact on stress reduction, "leading to positive impacts on neuroendocrine status, metabolic and cardio-vagal function."

The similarity of yoga and exercise's effect on cardiovascular risk factors, say the investigators, "suggest that there could be comparable working mechanisms, with some possible physiological aerobic benefits occurring with yoga practice, and some stress-reducing, relaxation effect occurring with aerobic exercise."

Commenting on the results, senior author Professor Myriam Hunink from Erasmus University Medical Center, Rotterdam, and Harvard School of Public Health, Boston, said that, although the evidence of yoga's beneficial effect in cardiovascular health is growing, a physiological explanation for this effect remains unclear. "Also unclear," she added, "are the dose-response relationship and the relative costs and benefits of yoga when compared to exercise or medication. However, these results indicate that yoga is potentially very useful and in my view worth pursuing as a risk improvement practice."

Moreover, in view of yoga's ease of uptake, the investigators also note that evidence supports yoga's acceptability to "patients with lower physical tolerance like those with pre-existing cardiac conditions, the elderly, or those with musculoskeletal or joint pain."

Thus, they conclude that "yoga has the potential to be a cost-effective treatment and prevention strategy given its low cost, lack of expensive equipment or technology, potential greater adherence and health-related quality of life improvements, and possible accessibility to larger segments of the population."

Yoga, meditation may help train brain to help people control computers with their mind

Date: September 25, 2014

Source: University of Minnesota

Summary:
People who practice yoga and meditation long term can learn to control a computer with their minds faster and better than people with little or no yoga or meditation experience, new research by biomedical engineers shows. The research could have major implications for treatments of people who are paralyzed or have neurodegenerative diseases.

New research by biomedical engineers at the University of Minnesota shows that people who practice yoga and meditation long term can learn to control a computer with their minds faster and better than people with little or no yoga or meditation experience. The research could have major implications for treatments of people who are paralyzed or have neurodegenerative diseases.

The research is published online in TECHNOLOGY, a new scientific journal featuring cutting-edge new technologies in emerging fields of science and engineering.

In the study, researchers involved a total of 36 participants. One group of 12 had at least one year of experience in yoga or meditation at least two times per week for one hour. The second group included 24 healthy participants who had little or no yoga or meditation experience. Both groups were new to systems using the brain to control a computer. Both groups participated in three, two-hour experiments over four weeks in which they wore a high tech, non-invasive cap over the scalp that picked up brain activity. The participants were asked to move a computer cursor across the screen by imaging left or right hand movements.

The participants with yoga or meditation experience were twice as likely to complete the brain-computer interface task by the end of 30 trials and learned three times faster than their counterparts for the left-right cursor movement experiments.

"In recent years, there has been a lot of attention on improving the computer side of the brain-computer interface but very little attention to the brain side," said lead researcher Bin He, a biomedical engineering professor in the University of Minnesota's College of Science and Engineering and director of the University's Institute for Engineering in Medicine. "This comprehensive study shows for the first time that looking closer at the brain side may provide a valuable tool for reducing obstacles for brain-computer interface success in early stages."

Researchers have been increasingly focused on finding ways to help physically disabled individuals who are paralyzed, have lost limbs, or suffer from diseases such as ALS or cerebral palsy. In these cases, brain function remains intact, but these people have to find a way to bypass muscular control to move a wheelchair, control an artificial limb, or control other devices.

Professor He gained international attention in 2013 when members of his research team were able to demonstrate flying a robot with only their minds. However, they found that not everyone can easily learn to control a computer with their brains. Many people are unsuccessful in controlling the computer after multiple attempts. A consistent and reliable EEG brain signal may depend on an undistracted mind and sustained attention. Meditators have shown more distinctive EEG patterns than untrained participants, which may explain their success.

Professor He said he got the idea for the study more than five years ago when he began his brain-computer interface research and noticed one woman participant who was much more successful than other participants at controlling the computer with her brain. The woman had extensive experience with yoga and mediation, referred to by researchers as Mind-Body Awareness Training (MBAT).

The next step for He and his team is to study a group of participants over time who are participating in yoga or meditation for the first time to see if their performance on the brain-computer interface improves.

"Our ultimate goal is to help people who are paralyzed or have brain diseases regain mobility and independence," He said. "We need to look at all possibilities to improve the number of people who could benefit from our research."

Yoga relieves multiple sclerosis symptoms, study shows

Date: September 2, 2014

Source: Rutgers University

Summary:
A specialized yoga program is beneficial to everyday living for those with multiple sclerosis, a study concludes. After an eight-week trial, the researchers found that participants had better balance, fine motor coordination, an improved quality of life and a decrease in pain and fatigue.

Paula Meltzer was only 38 when out of nowhere everything she looked at was blurry. For the single mother, who had a lucrative career as a gemologist and spent hours examining valuable pieces of jewelry, it seemed as if -- in a split second -- her life changed.

At first doctors thought Meltzer had a brain tumor. What they determined after further tests, however, was that she had multiple sclerosis, an autoimmune disease that affects the brain and central nervous system and was causing optic neuritis, an inflammation of the optic nerve that can cause a partial or complete loss of vision.

"I was living independently, doing my job, taking care of my child and then I had to look to my parents to take care of me," Meltzer said.

Almost two decades later, Meltzer, out of a wheelchair and walking without a cane, was one of 14 women with moderate disability due to MS who participated in a pilot trial conducted by the Rutgers School of Health Related Professions. A specially-designed yoga program for these MS patients not only improved their physical and mental well-being but also enhanced their overall quality of life.

"I felt like I became steadier and stronger in my core," Meltzer said. Prior to yoga, she described herself as a "wall walker," someone who felt safer holding onto the wall in order to get around. "To be able to stand on one leg and feel balanced is amazing."

Susan Gould Fogerite, director of research for the Institute for Complementary and Alternative Medicine in the School of Health Related Professions, said that although there is widespread evidence that yoga is being used as a form of exercise by those with MS, much of the feedback has been anecdotal and there isn't much empirical data regarding its safety and efficacy.

This is why she and her colleagues, Evan Cohen and David Kietrys, physical therapists and associate professors in the School of Health Related Professions at Stratford, decided to undertake the small pilot study, believing that a specialized yoga program for MS patients -- which incorporates mind, body and spirit -- would be beneficial to everyday living.

What they discovered at the end of the eight-week trial was that those who participated were better able to walk for short distances and longer periods of time, had better balance while reaching backwards, fine motor coordination, and were better able to go from sitting to standing. Their quality of life also improved in perceived mental health, concentration, bladder control, walking, and vision, with a decrease in pain and fatigue.

"Yoga is not just exercise, it is a whole system of living," said Fogerite, an associate professor, who, along with Kietrys, will present the results on September 26 at the Symposium on Yoga Research at the Kripalu Institute in Massachusetts. "The panel of experts who advised us on the trial wanted to make sure that we provided a fully integrated program that included philosophy, breathing practices, postures, relaxation and meditation."

The yoga pilot trial was held at Still Point Yoga Center in Laurel Springs, a southern New Jersey town close to Philadelphia. Of the 72 individuals who were interested in participating, only 16 were eligible based on medical and other criteria and availability. Of those, 15 were enrolled and 14 completed the program after one person had to withdraw because of an unrelated health problem.

Meltzer and the other women who participated in the trial ranged in age from 34 to 64. Some had been diagnosed with MS within the last two years while others had been living with the illness for up to 26 years. For 90 minutes, twice a week for two months, they practiced techniques and exercises that would improve their posture, help to increase stamina, and teach them how to relax and focus.

"This study, I hope, is one of many that will give us the clinical information we need," said Fogerite. "Yoga is not currently being widely prescribed for people with MS, although it might turn out to be a very helpful treatment."

The yoga practices were done by the women in the study sitting, standing, or lying on yoga mats, and using metal folding chairs situated close to the wall to provide them with more support.

"What was so nice about this experience was that although everyone was at a different level of the disease, we felt like we were all together, so I think the camaraderie helped," said Meltzer. "And it wasn't just about gaining more mobility and balance in our legs but our arms and necks felt stronger as well."

Fogerite said a larger randomized controlled trial would be needed to determine whether yoga could be used as a prescribed treatment for individuals with moderate disability due to MS. More than 2.3 million people -- two to three times more women than men -- throughout the world are diagnosed with this disease which can cause poor coordination, loss of balance, slurred speech, tremors, numbness, extreme fatigue and problems with memory and concentration.

"When I was first diagnosed I no longer felt safe in my own body," Meltzer said. "I didn't trust my body at all. What the program did was really bring that trust back."

Specialized yoga program could help women with urinary incontinence

Summary:
An ancient form of meditation and exercise could help women who suffer from urinary incontinence, according to a new study. researchers discovered that a yoga training program, designed to improve pelvic health, can help women gain more control over their urination and avoid accidental urine leakage. Men were not included in this study because urinary incontinence in men is often related to problems related to the prostate, which may be less likely to improve with yoga.

An ancient form of meditation and exercise could help women who suffer from urinary incontinence, according to a new study from UC San Francisco.

In a study scheduled to be published on April 25, 2014 in Female Pelvic Medicine & Reconstructive Surgery, the official journal of the American Urogynecologic Society, UCSF researchers discovered that a yoga training program, designed to improve pelvic health, can help women gain more control over their urination and avoid accidental urine leakage.

"Yoga is often directed at mindful awareness, increasing relaxation, and relieving anxiety and stress," said first author Alison Huang, MD, assistant professor in the UCSF School of Medicine. "For these reasons, yoga has been directed at a variety of other conditions -- metabolic syndrome or pain syndromes -- but there's also a reason to think that it could help for incontinence as well."

Huang and her colleagues recruited 20 women from the Bay Area who were 40 years and older and who suffered from urinary incontinence on a daily basis. Half were randomly assigned to take part in a six-week yoga therapy program and the other half were not. The women who took part in the yoga program experienced an overall 70 percent improvement -- or reduction -- in the frequency of their urine leakage compared to the baseline. The control group -- or the group that did not start yoga therapy -- only had 13 percent improvement. Most of the observed improvement in incontinence was in stress incontinence, or urine leakage brought on by activities that increase abdominal pressure such as coughing, sneezing, and bending over.

Huang and her colleagues believe that yoga can improve urinary incontinence through more than one mechanism. Because incontinence is associated with anxiety and depression, women suffering from incontinence may benefit from yoga's emphasis on mindful meditation and relaxation. But regular practice of yoga may also help women strengthen the muscles of the pelvic floor that support the bladder and protect against incontinence.

"We thought this would be a good opportunity for women to use yoga to become more aware of and have more control over their pelvic floor muscles," Huang said.

Approximately 25 million adults in America suffer from some form of urinary incontinence, according to the National Association for Continence. Up to 80 percent of them are women. Urinary incontinence becomes more common as women age, although many younger women also suffer from it.

"We specifically developed a yoga therapy program that would be safe for older women, including women with minor mobility limitations," Huang said. "So we were partially assessing safety of this program for older women who are at highest risk for having incontinence in the first place."

Not all types of yoga may help with urinary incontinence. The yoga program used in the study was specially designed with input from yoga consultants Leslie Howard and Judith Hanson Lasater, who have experience teaching women to practice yoga in ways that will improve their pelvic health. Still Huang and her colleagues believe that many women in the community can be taught to preserve pelvic muscle strength and prevent incontinence.

"It would be a way for women to gain more control over their pelvic floor muscles without having to go through traditional costly and time-intensive rehabilitation therapy," Huang said.

Men were not included in this study because urinary incontinence in men is often related to problems related to the prostate, which may be less likely to improve with yoga. Huang and her colleagues hope to eventually build on this study and double the length of the study to 12 weeks.

Yoga can help keep expectant mothers stress free: First evidence found

Date: April 30, 2014

Source: Manchester University

Summary:
The effects of yoga on pregnant women has been studied, with results showing that it can reduce the risk of anxiety and depression. Stress during pregnancy has been linked to premature birth, low birth weight and increased developmental and behavioral problems in the child as a toddler and adolescent, as well as later mental health problems in the mother. A high level of anxiety during pregnancy is linked with postnatal depression which in turn is associated with increased risk of developing depression later in life.

For the first time, researchers in the UK have studied the effects of yoga on pregnant women, and found that it can reduce the risk of them developing anxiety and depression. Stress during pregnancy has been linked to premature birth, low birth weight and increased developmental and behavioural problems in the child as a toddler and adolescent, as well as later mental health problems in the mother. A high level of anxiety during pregnancy is linked with postnatal depression which in turn is associated with increased risk of developing depression later in life.

While it has long been assumed by medical professionals that yoga can help reduce stress levels in mothers, it had never been tested in a research setting.

But in a paper published today in the journalDepression and Anxiety, academics, from Manchester and Newcastle Universities, show that women who attended a yoga class a week for eight weeks had decreased anxiety scores compared to the control group who received normal antenatal treatment. Dr James Newham, who carried out the research as a PhD student at Tommy's Maternal and Fetal Health Research Centre at the University of Manchester, and is now a research associate at Newcastle University, said: "It is surprising this has never been looked at before, we have long believed that it works but no research had been done to back up the theory.

"We have now gone some way to prove that it can help. It was not a small effect either. This has the potential to really help mothers who are feeling anxious about their pregnancy."

Professor John Aplin, one of the senior investigators in Manchester, and himself a long standing yoga teacher, said: "Yoga incorporates relaxation and breathing techniques with postures that can be adapted for pregnant women. Many women opt to practice yoga during their pregnancy but this is the first worldwide report on the effects of both single and multiple sessions of antenatal yoga on mood."

The study, funded by baby charity Tommy's, was carried out in Greater Manchester and looked at 59 women who were pregnant for the first time and asked them to self-report their emotional state. They were split into several groups, some of which took part in a yoga session a week for eight weeks, while the others just had normal pre-natal treatment. A single session of yoga was found to reduce self-reported anxiety by one third and stress hormone levels by 14%. Encouragingly, similar findings were made at both the first and final session of the 8 week intervention.

Dr Newham added: "There is a growing body of evidence that maternal antenatal anxiety may increase the risk of pre-term delivery and the likelihood of giving birth to a low birth weight child. If we can reduce these risk factors, and perhaps reduce the rate of post-natal mood disorders in mothers and negative health outcomes in their offspring, then that can only be a good thing."

Professor Aplin said: "The results confirm what many who take part in yoga have suspected for a long time. There is also evidence yoga can reduce the need for pain relief during birth and the likelihood for delivery by emergency caesarean section.

"Perhaps we should be looking at providing yoga classes on the NHS. It would be relatively cheap to implement, could help mothers and their children be healthier, as well as reducing the costs of longer term health care."

Jacqui Clinton, Health Campaigns Director at Tommy's said: "At least 1 in 10 women experience mental health problems during pregnancy, yet previous research from Tommy's has shown that the stigma is so great, many women never get help for their feelings. This study shows that pregnant women may be able to use yoga to reduce feelings of stress, anxiety and depression, which in turn may help prevent them developing post-natal depression. We already know that pregnancy yoga can help improve physical health and strength on the run up to having a baby, and this new evidence shows that it may have important benefits for women's emotional health too."
