Effects of backward walking training on balance, gait, and functional mobility in people with multiple sclerosis: A randomized controlled study.

ABSTRACT

BACKGROUND: Backward walking training (BWT) can have a positive effect on balance, gait, and functional mobility in neurological diseases; however, the effectiveness of BWT has not been examined in multiple sclerosis (MS). Therefore, the study aimed to investigate the effects of BWT on balance, gait, and functional mobility in people with MS (PwMS). METHOD: Nineteen PwMS were randomly allocated to either the experimental group (n=10) and the control group (n=9). The experimental group received BWT in addition to conventional walking training (CWT) while the control group only received CWT. Both groups performed training three times a week for 8 weeks. Participants were assessed with the Berg Balance Scale (BBS), four square step test (FSST), activities-specific balance confidence scale (ABC), timed 25-foot walk test (T25FW), dynamic gait index (DGI), 3-meter backward walk test (3MBWT), Multiple Sclerosis Walking Scale-12 (MSWS-12), and timed up and go test (TUG) before and after training. RESULTS: After training, both groups showed significant improvements on the T25FW, and TUG (p<0.05) while only the experimental group showed significant improvements on the BBS, FSST, ABC, DGI, 3MBWT, and MSWS-12 (p<0.05). The experimental group significantly improved more than the control group in all outcomes (p<0.05) except for the T25FW (p=0.202). CONCLUSION: BWT in addition to CWT is an effective way to improve balance, gait, and functional mobility for PwMS. These results suggest that BWT may be a potentially useful treatment approach when added to CWT in the rehabilitation of MS.
