Contribution of Perceived Upper Limb Function to the Participation and Activity Levels Among Community-Dwelling...

To examine the contribution of perceived upper limb function to participation and activity among community-dwelling people with chronic stroke.

A cross-sectional study was conducted with eighty-one people with stroke aged ≥50 years. The outcome measures included the Oxford Participation and Activities Questionnaire (Ox-PAQ), Arm Activity Measure (ArmA), Wolf Motor Function Test (WMFT), Timed Up and Go Test (TUG), and Geriatric Depression Scale (GDS).

Correlation analyses revealed that perceived upper limb function, as measured using the ArmA, had the strongest and most significant correlations with the levels of participation and activity, as measured using the Ox-PAQ, among all of the tested variables (rs=0.35-0.59, p<0.01). Multiple linear regression analyses also showed that perceived upper limb function significantly associated the levels of participation and activity, accounting for 2.0% to 9.0% of the variance in the Ox-PAQ scores. The final model, which included TUG time, the GDS score, the WMFT score, and the ArmA score, could explain 54% and 28% of the variance in the routine activities and social engagement subscales of the Ox-PAQ, respectively. The model including the GDS score, the WMFT score, and the ArmA score explains 32% of the variance in the emotional well-being subscale of the Ox-PAQ.

Perceived upper limb function is a crucial determinant of participation and activity among community-dwelling people with chronic stroke. It could thus be a target component of stroke rehabilitation interventions to facilitate participation and activity after stroke.
