Background and Purpose— In research on Constraint-Induced Movement (CI) therapy, a structured interview, the Motor Activity Log (MAL), is used to assess how stroke survivors use their more-impaired arm outside laboratory. This article examines psychometrics of 14-item version this instrument in 2 chronic samples with mild-to-moderate upper-extremity hemiparesis. Methods— Participants (n=41) first study completed MALs before after CI therapy or placebo control procedure. addition, caregivers independently MAL participants. (n=27) second wore accelerometers that monitored movements for 3 days laboratory an automated form therapy. Results— Validity participant Quality (QOM) scale was supported. Correlations between pretreatment-to-posttreatment change scores QOM caregiver scale, amount (AOU) accelerometer recordings were 0.70, 0.73, 0.91 ( P <0.01), respectively. Internal consistency α >0.81), test-retest reliability r >0.91), stability, responsiveness (ratio >3) also The AOU scales internally consistent, stable, sensitive, but not reliable. Conclusions— can be exclusively reliably validly measure real-world, rehabilitation outcome functional status patients
