Abstract

Objective: To determine whether robotic metrics: (1) correlate with the Nine-Hole Peg Test (9HPT; good convergent validity); and (2) differentiate between those self-reporting “some hand problems” versus “no hand problems” (good criterion validity). Design: Cross-sectional validation analyses. Setting: Rehabilitation research laboratory located within a hospital. Participants: People with multiple sclerosis self-reporting “some” (n=21; mean age, 52.52±10.69 y; females, n=16; disease duration, 18.81±10.38 y) versus “no” (n=21; age, 51.24±12.73 y; females, n=14; disease duration, 17.71±10.16 y) hand problems. Main Outcome Measures: We assessed hand function using the criterion standard 9HPT and robotic testing. Robotic outcomes included an overall task score, as well as 2 movement planning (ie, reaction time and initial direction angle) and 2 movement correction (ie, movement time and path length ratio) spatiotemporal values. We identified participants reporting “some” versus “no” hand problems via the Multiple Sclerosis Impact Scale-29. We analyzed our nonparametric data using a Mann–Whitney U test and Spearman rank-order correlation. Results: Those reporting “some hand problems” included more right-handed individuals (P=.038); otherwise, the 2 groups were characteristically similar. Visually guided reaching task score and movement planning but not movement correction spatiotemporal values demonstrated moderate correlations with 9HPT for both the dominant (reaction time: r=0.489, P=.001; initial direction angle: r=0.429, P=.005) and nondominant (reaction time: r=0.521, P
