Objective : To assess the safety and efficacy of iStrideTM device usage in the home environment for chronic stroke survivors with hemiparetic gait.
Design : Descriptive case report (2 subjects).
Setting : The participants' home.
Participants (or Animals, Specimens, Cadavers) : Subjects were recruited via volunteer sample. Subject A was 2 years post-stroke and Subject B was 25 years post-stroke. Eligibility criteria included: age 21-80, one of more cerebral stroke (on same side), stroke occurred at least 6 months ago, and gait asymmetry but able to walk independently with or without a cane.
Interventions : Twelve sessions ambulating on the iStrideTM device for 30 mins (three times per week for four weeks). Sessions were supervised by a physical therapist.
Main Outcome Measure(s) :
Primary Outcome: Gait speed 10 Meter Walk Test (10MWT) and secondary outcome measures included: Timed Up and Go Test (TUG), Berg Balance Scale (BBS), Functional Gait Assessment (FGA), and Stroke Specific Quality of Life Scale (SS-QOL)
Results : At the one-week follow-up, Subject A increased gait speed 0.44m/sec (220%), TUG 11.8 secs, BBS 10 points, and FGA 100%. Subject B increased gait speed 0.4m/sec (63%), TUG 4.63 secs, BBS 4 points, and FGA 23.5%. Improvements were beyond the minimal detectable change or meaningful change values for each measure. Both subjects also improved gait speed and fall risk categories as indicated by these measures. Additionally, SS-QOL scores increased by 21% for Subject A and 40% for Subject B.
The iStrideTM device can be used in the home environment to help stroke survivors increase gait speed, reduce fall risk, and improve self-reported quality of life many years post-stroke.
