Objective: To determine if clinical evaluations of poststroke arm function correspond to everyday motor performance indexed by arm accelerometers. Design: Cross-sectional study analyzing baseline data from a larger trial (NCT02665052). Setting: Outpatient research center. Participants: Community-dwelling adults (N=20) with chronic arm motor deficits (stroke≥6mo). Intervention: A total of 72 hours of home wrist-worn accelerometry during normal routine. Main Outcome Measures: Clinical evaluations included the Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT), Wolf Motor Function Test (WMFT), and 2 self-assessments: the Motor Activity Log (MAL) and hand motor subscale of the Stroke Impact Scale (SIS). Accelerometer-derived variables included quantifications of movement intensity (magnitude) and duration of arm use. Results: Participants had moderate arm impairment (FMA, 36.1±9.4). The accelerometer-derived mean magnitude ratio correlated significantly with the FMA (ρ=0.60, P
