摘要
Objectives: To (1) determine whether acceleration metrics derived from monitoring outside of treatment are responsive to change in upper extremity (UE) function; and secondarily to (2) compare metric values during task-specific training and while in the free-living environment, and (3) establish metric associations with an in-clinic measure of movement capabilities. Design: Before-after observational study. Setting: Inpatient hospital (primary purpose); outpatient hospital (secondary purpose). Participants: Individuals (n=8) with UE hemiparesis <30 days poststroke (primary purpose); individuals (n=27) with UE hemiparesis >= 6 months poststroke (secondary purpose). Intervention: The inpatient sample was evaluated for UE movement capabilities and monitored with wrist-Worn accelerometers for 22 hours outside of treatment before and after multiple sessions of task-specific training. The outpatient sample was evaluated for TIE movement capabilities and monitored during a single session of task-specific training and the subsequent 22 hours outside clinical settings. Main Outcome Measures: Action Research Arm Test (ARAT) and acceleration metrics quantified from accelerometer recordings. Results: Five metrics improved in the inpatient sample, along with TIE function as measured on the ARAT: use ratio, magnitude ratio, variation ratio, median paretic UE acceleration magnitude, and paretic UE acceleration variability. Metric values were greater during task-specific training than in the free-living environment, and each metric was strongly associated with ARAT score. Conclusions: Multiple metrics that characterize different aspects of TIE movement are responsive to change in function. Metric values are different during training than in the free-living environment, providing further evidence that what the paretic UE does in the clinic may not generalize to what it does in everyday life.
