Numerous measures are readily available to clinicians for the evaluation of UE function post-stroke. Many of these measures have been thoroughly evaluated for reliability and validity at multiple time points post stroke. The measures can be generally divided into two categories: 1) performance measures, where the clinician rates or times a series of UE actions that are performed by the patient, or self-report measures, where the clinician asks a series of questions about UE actions that are answered verbally by the patient or by proxy. The most frequently cited UE performance measures include the Action Research Arm Test (ARAT), Box and Blocks Test (BB), Chedoke Arm and Hand Activity Inventory (CAHAI), Jebsen-Taylor Hand Function Test (JTT), Nine-Hole Peg Test, and the Wolf Motor Function Test (WMFT). The most frequently cited self-report measures include the Stroke Impact Scale (SIS) and the Motor Activity Log (MAL).
