wring with two hands

The Chedoke Arm and Hand Activity Inventory (CAHAI) is a validated, upper-limb measure that uses a 7-point quantitative scale in order to assess functional recovery of the arm and hand after a stroke. The purpose of this measure is to evaluate the functional ability of the paretic arm and hand to perform tasks that have been identified as important by individuals following a stroke.

The CAHAI is a performance test using functional items. It is NOT designed to measure the client’s ability to complete the task using only their unaffected hand, but rather to encourage bilateral function. There are 4 versions of the CAHAI, all having good psychometric properties (CAHAI-7,-8,-9,-13). Administration times vary with the selected version (approximately 15-30 minutes).
