Critically appraised paper: Task-oriented gait training that focuses on the safe and correct use of a walking aid may reduce falls in people with multiple sclerosis [commentary]

OBJECTIVE: To evaluate the effect of the Assistive Device Selection, Training and Education Program (ADSTEP) on falls and walking and sitting activity in people with multiple sclerosis (PwMS). DESIGN: Randomized controlled trial. SETTING: Veterans affairs medical center. PARTICIPANTS: PwMS (N=40) using a walking aid at baseline who had fallen in the previous year. INTERVENTIONS: Participants were randomly assigned to ADSTEP or control. ADSTEP had 6 weekly, 40-minute, 1-on-1 sessions with a physical therapist, starting with walking aid selection and fitting, followed by task-oriented progressive gait training. Control was usual medical care with the option of ADSTEP after the study. MAIN OUTCOME MEASURES: The following were assessed at baseline, intervention completion, and 3 months later: falls, timed Up and Go, timed 25-foot walk, 2-minute walk, Four Square Step Test, International Physical Activity Questionnaire, Quebec User Evaluation of Satisfaction with Assistive Technologies, Multiple Sclerosis Walking Scale-12, Activities-Specific Balance Confidence Scale, and Multiple Sclerosis Impact Scale-29. Effect on these outcomes was estimated by a 2-by-2 repeated measures general linear model. RESULTS: Fewer ADSTEP than control participants fell (χ(2)=3.96, P.05. ADSTEP 117.53±148.40min/d; control 46.43 ±58.55min/d; d=0.63). CONCLUSIONS: ADSTEP prevents falls, reduces sitting, and may increase walking in PwMS.
