| Summary: | Reaching Performance Scale for Stroke (RPSS) evaluates the upper limb reach-to-grasp movement quality and compensatory movements. The objective of the study was to test the reliability, construct validity, and interpretability of the Brazilian-Portuguese RPSS.
Fifty-one individuals (mean age 62 ± 10.8 years), with acute-to-chronic stroke (range: 1-300 months) were video recorded while performing a reach-to-grasp task of a cone placed both close and far from the individual. Their degree of motor impairment ranged from 4 to 59 points in the Fugl-Meyer scale.
Reaching Performance Scale for Stroke showed excellent intra- (ICC

= 0.98-0.99) reliability, and redundant internal consistency (Cronbach's α = 0.98). The construct validity between RPSS and Fugl-Meyer scale was strong (Spearman rho = 0.88-0.89; p < 0.0001). The scale was able to discriminate individuals with mild or moderate upper limb impairment from those with severe impairment. We found ceiling and floor effects.
Reaching Performance Scale for Stroke showed excellent reliability and redundant internal consistency. The construct validity with the Fugl-Meyer scale was strong. Reaching Performance Scale for Stroke was able to discriminate individuals with different levels of upper limb impairment.
IMPLICATIONS FOR REHABILITATION
Post-stroke individuals develop compensatory strategies to perform reaching movements with the paretic upper limb.
The Reaching Performance Scale for Stroke provides a quantitative and qualitative evaluation of the reach-to-grasp movement.
The Reaching Performance Scale for Stroke is suitable for use with Brazilian-Portuguese speakers and has adequate reliability and validity. |
