  • Title: Improving gait in multiple sclerosis using robot-assisted, body weight supported treadmill training.
    Author: Lo AC, Triche EW.
    Journal: Neurorehabil Neural Repair; 2008; 22(6):661-71. PubMed ID: 18971381.
    Abstract:
    BACKGROUND: The majority of patients with multiple sclerosis (MS) develop progressive gait impairment, which can start early in the disease and worsen over a lifetime. A promising outpatient intervention to help improve gait function with potential for addressing this treatment gap is task-repetitive gait training. METHODS: Body weight supported treadmill training (BWSTT) with or without robotic assistance (Lokomat) was tested using a randomized crossover design in 13 patients with relapsing-remitting, secondary progressive or primary progressive MS. Patients received 6 training sessions over 3 weeks of each intervention. Outcomes included changes in the timed 25-foot walk (T25FW), the 6-minute walk treadmill test (6MW) distance, the Kurtzke Expanded Disability Status Scale (EDSS), as well as double-limb support time and step length ratio. RESULTS: There were no major differences in outcomes between treatment groups. The study population significantly improved on gait outcomes and the EDSS following BWSTT, including a 31% improvement in the T25FW, a 38.5% improvement in the 6MW, and a 1-point gain for the EDSS. Differences in pre/post changes were noted depending on gender, disease subtype, affected limb, and baseline EDSS. CONCLUSIONS: Although no differences in gait outcomes or the EDSS were found between treatment groups, this small pilot study of task-repetitive gait training resulted in significant within-subject improvements. BWSTT appears to be an activity-dependent intervention with potential to reduce gait impairment in MS.
