Weight Training May Help Parkinson’s Patients Retain Function

THURSDAY, Feb. 16 (HealthDay News) — When it comes to helping
Parkinson’s disease patients retain vital motor function, weight training
may be more effective than stretching or balance exercises, a new study
concludes.

The findings “reconfirm our notions that exercise plays an important
part in the treatment of Parkinson’s disease,” according to one outside
expert, Dr. Nora Chan, director of the Movement Disorder Program at
Winthrop-University Hospital, in Mineola, N.Y.

The research involved 48 people with Parkinson’s who were randomly
assigned to either a weight-training program or a workout routine that
included flexibility, balance and strengthening routines. Both groups
exercised for one hour, twice a week for two years.

The severity of the patients’ motor symptoms, including tremors, was
assessed after six, 12, 18, and 24 months of exercise. The symptoms were
checked when the patients were not taking their medication.

Both groups showed improvements in motor symptoms at six months. But
patients in the weight-training group had a 7.3 point improvement in their
Unified Parkinson’s Disease Rating Scale after two years, while the
patients in the other group returned to the same scores they had at the
start of the study.

The findings are being released early but will be presented at the
American Academy of Neurology’s annual meeting in New Orleans in
April.

“While we have known that many different types of exercise can benefit
Parkinson’s patients over short time periods, we did not know whether
exercise improves the motor symptoms of Parkinson’s over the long term,”
study author Daniel Corcos, at the University of Illinois at Chicago,
said in an AAN news release.

“Our results suggest that long-term weight training could be considered
by patients and doctors as an important component in managing Parkinson’s
disease,” he added.

Another expert, Dr. Andrew Feigin, said the study is one of many that
seems to support the notion “that regular strenuous exercise may have
long-term benefits for Parkinson’s disease patients.” However,
participants knew which type of exercise they were being assigned, so that
might have influenced their mood or motivation, according to Feigin, a
neurologist specializing in Parkinson’s disease at the Feinstein Institute
for Medical Research in Manhasset, N.Y

For her part, Chan added that “further studies are needed to clarify
whether certain exercises are more suitable for patients with different
symptoms, in different stages of disease, how cost effective these various
programs are, and the exact mechanisms by which exercise improves
Parkinson’s disease symptoms.”

Findings presented at medical meetings are considered preliminary until
publication in a peer-reviewed journal.
