Brief summary
Over half of persons with multiple sclerosis (MS) report falling over a 6-month period and a majority of those who fall require medical attention for injuries. Importantly, balance dysfunction, muscle weakness, and spasticity are modifiable risk factors for falls among community-dwelling older adults and likely persons with MS. Indeed, there is evidence that these physiological risk factors can be minimized with exercise training in persons with MS and this might translate into a decrease in fall risk as documented in community-dwelling older adults. The investigation will examine the effectiveness of a home-based exercise program that is designed to reduce fall risk by targeting specific fall risk factors including balance dysfunction and two of its latent causes, muscle weakness and spasticity in persons with multiple sclerosis. It is predicted that persons who receive home-based exercise program will have a reduction in fall risk.
Detailed description
Over half of persons with multiple sclerosis (MS) report falling over a 6-month period and half of those who fall require medical attention for injuries. To make matters worse, a fall can result in activity curtailment, physiological deconditioning, and institutionalization. Importantly, balance dysfunction, muscle weakness, and spasticity are modifiable risk factors for falls among community-dwelling older adults and likely persons with MS. Indeed, there is evidence that these physiological risk factors can be minimized with exercise training in persons with MS and this might translate into a decrease in fall risk as documented in community-dwelling older adults. To that end, an appropriately designed exercise training program that targets specific, modifiable risk factors might be effective for decreasing the fall risk in persons with MS. The investigation will examine the effectiveness of a home-based exercise program that is designed to reduce fall risk by targeting specific fall risk factors including balance dysfunction and two of its latent causes, muscle weakness and spasticity in persons with multiple sclerosis. It is predicted that persons who receive home-based exercise program will have a reduction in fall risk. Participants will undergo multidimensional assessment of walking, balance, muscle strength, spasticity and fall risk prior to and immediately following the 12 week intervention. Following baseline assessment participants will be randomized into intervention or control groups. The intervention group will receive exercise instruction 4 times over 2 months. The home-based exercise protocol will focus on improving balance, walking, lower limb and core muscle strength, and spasticity, all potential determinants of falling.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Physiological Fall risk | 3 months | Physiological fall risk will be determined by the physiological profile assessment which assesses physiological function related to fall risk by combining measures of vision, proprioception, lower-limb strength, postural sway, and cognitive function. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mobility | 3 months | Mobility will be quantified with performance on timed 25 foot walk (T25W), timed up and go (TUG), Six spot step test, 6 minute walk and the MS walking scale-12. |
| Balance | 3 Months | Balance will be quantified with the Berg Balance scale; self-report of balance impairment (ABC); and force platform metrics (sway range and velocity). |
| Spasticity | 3 Months | Spasticity will be assessed with the modified ashworth scale. |
