Highlights
- •Paretic lower limb strength and mobility are predictors of physical health-related quality of life.
- •Faster mobility, lower age, and comorbidities predicted better social integration.
- •Poor recovery of strength and mobility affects community reintegration poststroke.
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 R2=.30). The total paretic lower limb torque and TUG test predicted the SIPSO physical
component (adjusted R2=.47). The total paretic lower limb torque significantly predicted the SF-36 Mental
Component Summary, but the adjusted R2 was low (.06). Similarly, the TUG test significantly predicted the SIPSO social component,
but again the adjusted R2 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.
