Objective To evaluate the mobility and postural balance improvements that could be achieved in a cohort of persons with multiple sclerosis (MS) who participated in a motor adaptation protocol and a cohort of persons with MS who participated in a therapeutic exercise protocol. Design A cohort design, where subjects were evaluated before and after a 6-week intervention period. Setting Clinical laboratory setting. Participants Individuals (N=42) with relapsing-remitting or secondary progressive MS (Expanded Disability Status Scale [EDSS] scores, 3.0–6.5) were initially screened for eligibility for participation in the study, from which those who fit the inclusion criteria (n=32) were enrolled in the study. Subjects were pseudorandomly assigned to a treatment group and matched based on EDSS scores. Fourteen individuals in the motor adaptation cohort (MAC) (mean age ± SD, 52.6±9y; mean EDSS score ± SD, 5.5±0.9) and 13 individuals in the therapeutic exercise cohort (TEC) (mean age ± SD, 54.0±9y; mean EDSS score ± SD, 5.3±0.9) completed the entire duration of their respective programs. Interventions Both cohorts completed their therapy twice a day, 5 days each week, for 6 weeks. Each session of the MAC program consisted of balance and gait training that encouraged new ways to adapt to challenging task demands. The TEC program was similar to a traditional exercise program. Main Outcome Measures The Sensory Organization Test, 6-minute walk test, and gait spatiotemporal kinematics. Results Collectively, both treatment groups had improvements in postural balance (P=.001), walking endurance (P=.002), walking speed (P=.004), and step length (P<.001) after therapy. However, there were no statistical differences between the 2 treatment groups for any of the outcome variables (P values >.01). Conclusions Our exploratory results suggest that a high frequency of physical therapy rather than a specific activity focus might be an important parameter for persons with MS.
