Test-Retest Reliability, Validity, and Sensitivity of the Chedoke Arm and Hand Activity Inventory: A New Measure of Upper-Limb Function for Survivors of Stroke

OBJECTIVES: To estimate the test-retest reliability and validity of the Chedoke Arm and Hand Activity Inventory (CAHAI) and to test whether the CAHAI was more sensitive to change in upper-limb function than the Impairment Inventory of the Chedoke-McMaster Stroke Assessment (CMSA) and the Action Research Arm Test (ARAT).
