In a small pilot study, researchers analyzed the possible benefits of
yoga among chronic stroke survivors – whose stroke had occurred more
than six months prior.
This study involved 47 participants with
around three-quarters of them being male veterans, were divided into
three groups; twice weekly group yoga for eight weeks, a twice weekly
“yoga-plus” group and used a relaxation recording three times a week and a usual medical care group without rehabilitation.

Teaching the yoga classes was a registered therapist that included
modified yoga postures, relaxation and meditation, with classes growing
more challenging each week.
Those who had completed yoga or
“yoga-plus” had shown significant improvement in their balance in
comparison to the usual medical group.
Researchers note
balance problems frequently last long after a person suffers a stroke and are related to greater disability and higher risk of falls.
The study had also revealed that those survivors in the yoga groups had
improved scores for independence, quality of life and less fear of
falling.
Dr. Arlene Schmid,
PhD, O.T.R., lead researcher and a rehabilitation research scientist at
Roudebush Veterans Administration-Medical Center and Indiana
University, Department of Occupational Therapy in Indianapolis, Indiana,
stated in a public release "For chronic stroke patients, even if they
remain disabled, natural recovery and
acute rehabilitation therapy typically
ends after six months, or maybe a year.” Dr. Schmid is also an
assistant professor for occupational therapy at Indiana
University-Purdue University in Indianapolis and an investigator at the
Regenstrief Institute.
Improvements after the six-month window can take longer to occur, "but
we know for a fact that the brain still can change. The problem is the
healthcare system is not necessarily willing to pay for that change. The
study demonstrated that with some assistance, even chronic stroke
patients with significant paralysis on one side can manage to do
modified yoga poses,” says Dr. Schmid.
Among the participants in
the study, the oldest was 90’s and all participants had to be able to
stand on their own on the studies outset.
According to
researchers may be more therapeutic than traditional exercise due to the
combination of postures, breathing and meditation may produce different
effects than simple exercises.
Researchers can draw only
limited conclusions from the study because of its small number of
participants and lack of diversity. The study also didn't have enough
participants to uncover differences between the yoga and control groups.
The scientists hope to conduct a larger study soon.
Dr. Schmid
did add "However, stroke patients looking for such help might have a
hard time finding qualified yoga therapists to work with.” "Some
occupational and physical therapists are integrating yoga into their
practice, even though there's scant evidence at this point to support
its effectiveness."
Researchers also noticed improvements in the
mindset of patients about their disability. The participants talked
about walking through a grocery store instead of using an assistive
scooter, being able to take a shower and feeling inspired to visit
friends.
In closing Dr. Schmid says "It has to do with the
confidence of being more mobile," even though it took time to unfold
"these were very meaningful changes in life for people."
Last year Dr. Schmid conducted a
pilot study that
involved 19 men and 1 woman with an average age of 66 years. For a
period of eight weeks they took part in twice weekly hour long group
yoga classes taught by a yoga therapist that had modified the poses
dramatically to meet the needs of the veterans.
A range of balance items measured by the
Berg Balance Scale and
Fullerton Advance Balance Scale improved
by 17 percent and 34 percent respectively by the end of the program.
That study also revealed a measurable gain in confidence in their
balance.
The yoga performed in the study was modified to the
extent that Schmid said it would be very difficult to find a comparable
class offered publicly. Such a class should be taught by a yoga
therapist who has had additional training in anatomy and physiology and
how to work with people with disabilities.
The study had been funded by the Department of Veterans Affairs, QUERI.
Other
studies on yoga have revealed that
Hatha Yoga
practice by older adults who had a fear of falling demonstrated at the
end of the study a reduced fear of falling, increased lower body
flexibility and a reduction in their leisure constraints.
A study
out of Temple University Gait Study Center had revealed that a
particular type of yoga helped improved balance and stability in women
over the age of 65 years.
Dr. Jinsup Song,
DMP, PhD, at the School of Podiatric Medicine and the College of Health
Professions and at the School of Podiatric Medicine and the College of
Health Professions along with associates and co-author Marian Garfinkel,
Ed.D., a certified senior Iyengar Yoga instructor conducted the study.
Their study suggested that improving balance and stability through yoga
could help reduce the risk of falling, as these are two areas that are
often deficient when a fall occurs.
Garfinkel consulted her
mentor, renowned yoga master B.K.S. Iyengar, to craft a specific yoga
program of poses tailored to the elderly who have had little to no yoga
experience. The use of props in the Iyengar program allows participants
to gradually master the poses while building their confidence level.
In addition to improving balance and stability, Song notes that participation in a group setting, such as an
Iyengar yoga class, could have positive psychological effects for the elderly, as well.
"Throughout the program, participants consistently noted that they had a
better outlook on their day-to-day lives," he said. "The class gave
them something to look forward to; they found it engaging, and said that
if they couldn't attend a class, they definitely missed it."
