Robot-Assisted Gait Training in Older Patients with Comorbid Conditions: A Pilot Study.

PURPOSE: This study aimed to evaluate the efficacy of robot-assisted gait training (RAGT) in older patients with neurological gait disorder accompanied by various comorbidities.

MATERIALS AND

METHODS

We included Individuals aged ≥65 years with degenerative brain diseases or stroke causing gait disorders for >6 months in open-label, a pilot study. RAGT was performed for 30 min/day, 2 days/week for 12 weeks. The intensity was set to 60% of the individual's heart rate maximum reserve. Primary outcome measures were the Timed Up and Go (TUG) test and Berg Balance Scale (BBS). Secondary outcomes included Beck Depression Inventory (BDI), Short Form-36 (SF-36), and evaluation of satisfaction.

RESULTS

Thirteen participants completed 24 sessions. Neurological diseases included stroke (n = 7) and Parkinson's disease (n = 6); all patients had at least two other diseases. After RAGT, TUG test results significantly improved, and BBS scores increased. Furthermore, BDI scores decreased, and scores of social functioning and mental health domain in the SF-36 increased. Participants rated high scores on satisfaction of RAGT.

CONCLUSIONS

Our finding showed that RAGT is a safe and effective intervention for enhancing physical function, improving quality of life, and reducing depression levels in older patients with neurological gait disorder accompanied by various comorbidities.
