Abstract

Objective: To investigate the extent to which physical performance measures of strength, balance, and mobility taken at discharge from inpatient stroke rehabilitation can predict health-related quality of life (HRQoL) and community reintegration after 6 months. Design: Longitudinal study. Setting: University laboratory. Participants: Adults (N=75) recruited within 1 month of discharge home from inpatient stroke rehabilitation. Interventions: Not applicable. Main Outcome Measures: 36-Item Short Form Health Survey (SF-36) for HRQoL and Subjective Index of Physical and Social Outcome (SIPSO) for community reintegration. Physical performance measures were the 6-minute walk test, timed Up and Go (TUG) test, Berg Balance Scale, Community Balance and Mobility Scale, and isokinetic torque and power of hip, knee, and ankle on the paretic and nonparetic sides. Other prognostic variables included age, sex, stroke type and location, comorbidities, and motor FIM score. Results: Separate stepwise linear regressions were performed using the SF-36 and SIPSO as dependent variables. The total paretic lower limb torque and 6-minute walk test predicted the SF-36 Physical Component Summary (adjusted R-2=.30). The total paretic lower limb torque and TUG test predicted the SIPSO physical component (adjusted R-2=.47). The total paretic lower limb torque significantly predicted the SF-36 Mental Component Summary, but the adjusted R-2 was low (.06). Similarly, the TUG test significantly predicted the SIPSO social component, but again the adjusted R-2 was low (.09). Conclusions: Measures of physical performance including muscle strength and mobility at discharge can partially predict HRQoL and community reintegration 6 months later. Further research is necessary for more accurate predictions. (C) 2017 by the American Congress of Rehabilitation Medicine
