Background and Purpose
Comparative studies of exercise interventions for people with
Parkinson Disease (PD) rarely considered how one should
deliver the intervention. The objective of this study was to compare the
success of exercise when administered by 1) home exercise program, 2)
individualized physical therapy, or 3) a group class. We examined if common
comorbidities associated with PD impacted success of each intervention.
Methods
Fifty-eight people (age 63.9 ± 8) with PD participated. People
were randomized into: 1) home exercise program 2) individual physical
therapy or 3) group class intervention. All arms were standardized and based
on the Agility Boot Camp exercise program for PD, 3 times per week for 4
weeks. The primary outcome measure was the 7-item Physical Performance Test
(PPT). Other measures of balance, gait, mobility, quality of life, balance
confidence, depressions, apathy, self-efficacy and UPDRS motor and ADL
scores were included.
Results
Only the individual group significantly improved in PPT. The
individual exercise showed the most improvements in functional and balance
measures, while the group class showed the most improvements in gait. The
home exercise program improved the least across all outcomes. Several
factors effected success, particularly for the home group.
Discussion and Conclusions
An unsupervised, home exercise program is the least effective way to
deliver exercise to people with PD and individual and group exercises have
differing benefits. Furthermore, people with PD who also have other
comorbidities did better in a program directly supervised by a physical
therapist. Video Abstract available for additional insights
