exercise rehabilitation program in ms who use wheelchairs as a primary mobility device

Conditions: Multiple Sclerosis

Summary: approximately 50% of people with multiple sclerosis (ms) use a wheelchair within 30 years of the initial diagnosis. wheelchair use in ms is often associated with fatigue as a consequence of muscle weakness. indeed, fatigue, a prevalent consequence of ms, often becomes debilitating and exhausts energetic resources when carrying-out tasks of daily life and/or interacting with the community, as these require ambulatory mobility. this experience of excessive fatigue has its roots in muscle weakness and results in reliance on a wheelchair for mobility, and the dependency on a wheelchair may further reduce muscular strength, particularly of the lower extremities. we propose that wheelchair users with ms can increase muscular strength through a personalized exercise rehabilitation, and this in turn will improve ambulatory performance and possibly reduce fatigue. to date, no research has examined the effects of this specific exercise rehabilitation program (gh method) on physical function and other disease-related outcomes in persons with ms who use wheelchairs as a primary mobility device.

to date, there is a dearth of clinical trials examining exercise programs targeting wheelchair users with ms, but exercise programs are ideally suited for targeting the underlying causes of wheelchair use in this population, namely reduced lower extremity strength that manifests as excessive fatigue when undertaking tasks of daily life and/or interacting with the community. we propose examining a novel and highly relevant exercise rehabilitation program (gh method) on physical function and other disease-related outcomes in persons with ms who use wheelchairs as a primary mobility device. there are no relevant preliminary data in wheelchair users with ms, but the gh method has been successfully applied in other chronic, disabling diseases such as chronic kidney disease (ckd). the data from our previous and ongoing application of gh in ckd has supported improvements in a range of outcomes from physical frailty through quality of life. this proposed research will test the effects of a 6-month exercise rehabilitation program on physical function, self-reported health-related outcomes, and cognitive function in persons with ms who use wheelchairs as a primary mobility device in the community, but who are still ambulatory. these findings may guide researchers, clinicians, and exercise specialists in the advancement of future interventions for improving the lives of persons from this segment of the population with ms.
