Chedoke Arm and Hand Activity Inventory


Circle of Willis

The Chedoke Arm and Hand Activity Inventory (CAHAI) is used to assess functional ability of the paretic arm and hand.[1]

See also: Chedoke-McMaster Stroke Assessment

Intended Population

  • Upper Extremity Paralysis
  • Stroke (inpatient and outpatient)

Method of Use[1]

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.

This test consists of 13 functional tasks: 

  1. open a jar of coffee
  2. call 911
  3. draw a line with a ruler
  4. put toothpaste on a toothbrush
  5. cut medium consistency putty
  6. pour a glass of water
  7. wring out a washcloth
  8. clean a pair of eyeglasses
  9. zip up a zipper
  10. botton up 5 buttons
  11. dry back with a towel
  12. place a container on a table
  13. carry a bag up the stairs

There are 4 versions of CAHAI (CAHAI-7, -8, -9, and -13), all having good psychometric properties. Administration times vary with the selected version, approximately 15-30 minutes.

Equipment required:

  • Jar of coffee
  • Phone
  • Ruler and pen
  • Toothpaste and toothbrush
  • Knife
  • Fork
  • Putty
  • Glass of water
  • Wet washcloth
  • Eyeglasses
  • Jacket and zipper
  • Shirt with 5 buttons
  • Towel
  • Rubbermaid 38 liter container (50x37x27cm) with 10 lb. weight
  • Plastic gorcery bag with 4 lb. weight




Excellent interrater/intrarater reliability for stroke (ICC ranging from 0.96 - 0.99)[4] and upper extremity paralysis (ICC = 0.98)[5]

Perceived clinical utility:

Good results as an upper limb ability assessment for clients within 14 days of stroke.[6]
