Background: Weakness and difficulty walking are two of the most common symptoms for people with multiple sclerosis (MS). Weakness contributes to gait impairment, and strength training can improve muscle strength, but strength training does not lead to consistent improvements in gait in people with MS. This thesis hypothesized that one of the primary reasons for the inconsistent gait outcomes in the current literature is a failure to prioritize the appropriate lower extremity and trunk muscles for strength intervention. Purpose: The purpose of this thesis was to investigate the relationship of lower extremity and trunk muscle function to gait performance in people with MS in order to determine which muscles should be prioritized for strength training intervention to improve gait. Methods: The thesis consisted of three studies. Study One investigated the psychometric properties of a clinically feasible strength assessment protocol capable of assessing the major lower extremity and trunk muscles in a single session. Study Two examined the relative contributions of the major lower extremity and trunk muscles to gait speed and endurance in people with MS who had mild to moderate disability. Study Three determined the feasibility of improving both strength and gait outcomes using a strength training intervention targeting muscles found to be important contributors to gait in Study Two. Results: The results of Study One demonstrated that the muscle assessment protocol had acceptable reliability and validity. Study Two determined that ankle plantarflexion, hip abduction, trunk flexion had the strongest relative contributions to gait, and that disability may not change the relationship of muscle function to gait. Study Three determined that strength training of ankle plantarflexion, hip abduction, trunk muscles was feasible, and associated with improvements in gait. Conclusion: This thesis identified muscles important for gait that are not typically targeted in the current literature and provided preliminary evidence that strength training of these muscles is feasible and may improve both strength and gait. A future, randomized control trial targeting these muscles is warranted and may lead to more efficient and effective strength training intervention to improve gait in people with MS.
