A Reaching Performance Scale for 2 Wolf Motor Function Test Items.

To adapt the Reaching Performance Scale for Stroke (RPSS) for the Wolf Motor Function Test (WMFT) "Lift Can" (Can) and "Hand to Box" (Box) items. Retrospective analysis of video-recorded WMFT assessment performed by 3 raters on 2 occasions. Not applicable. Participants (N=29) with mild to moderate upper extremity impairment less than 3 months after stroke. Not applicable. Inter- and intra-rater agreement, concurrent validity of WMFT-RPSS. Mean ± SD inter-rater Gwet's agreement coefficient (AC2) was 0.61±0.05 for Can WMFT-RPSS and 0.56 (0.03) for Box. Mean ± SD intra-rater AC2 for Can was 0.63±0.05 and 0.70±0.04 for Box. WMFT-RPSS Can and Box scores correlated with log mean WMFT time (C, -0.73; B, -0.48), Functional Ability Scale (C, 0.87; B, 0.62), Upper Extremity Fugl-Meyer Motor Score (C, 0.69; B, 0.51), and item movement rate (C, 0.74; B, 0.71) (P<.05 for all). Mean ± SD WMFT-RPSS score across the 29 participants was 12.7±3.5 for Can (max score, 19) and 11.4±3.0 for Box (max score, 16). WMFT-RPSS demonstrated moderate intra-rater and weak-to-moderate inter-rater agreement for individuals with mild-moderate impairment. For construct validity, Can and Box WMFT-RPSS were significantly correlated with 4 standardized measures. Average WMFT-RPSS scores revealed that some participants may have relied on compensatory movements to complete the task, a revelation not discernable from movement rate alone. The WMFT-RPSS is potentially useful as a valid and reliable tool to examine longitudinal changes in movement quality after stroke. Copyright © 2020 American Congress of Rehabilitation Medicine.
