Chedoke Arm and Hand Activity Inventory - 7

Link to instrument: Link to Chedoke Arm and Hand Activity Inventory - 7

Acronym:

CAHAI - 7

Purpose:

The purpose of this measure is to evaluate the functional ability of the paretic arm and hand to perform tasks.

Description:

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 to complete (open jar of coffee, call 911, draw a line with a ruler, put toothpaste on toothbrush, cut medium consistency putty, pour a glass of water, wring out washcloth, clean pair of eyeglasses, zip up a zipper, do up 5 buttons, dry back with towel, place container on table, carry bag upstairs).

Area of Assessment: Activities of Daily Living, Upper Extremity Function

Standard Error of Measurement (SEM):

Not Established.

Minimal Detectable Change (MDC):

Upper Extremity Paralysis

 

(Barreca et al, 2005)

• MDC (90) = 6.3 points

Minimally Clinically Important Difference (MCID):

Not Established.

Cut-Off Scores:

Not Established.

Normative Data:

Not Established.

Test-retest Reliability:

Upper Extremity Paralysis:

 

("Psychometric properties: Reliability")

• Excellent reliability (ICC = 0.96)

Interrater/Intrarater Reliability:

Stroke: (Schuster, 2010; n = 23 patients (Mean age 69.4, SD 12.9: 6 females; Mean time post-stroke: 1.5y (2.5y))

• Excellent reliability (ICC = ranges from 0.96-0.99 for CAHAI-G 13, 9, 8, 7)

Upper Extremity Paralysis:

 

(Barreca et al, 2005)

• Excellent reliability (ICC = 0.98)

Internal Consistency:

Upper Extremity Paralysis:

 

("Psychometric properties: Reliability")

• Excellent reliability (ICC = 0.95)

Stroke:

• Excellent reliability (ICC = 0.967)

Criterion Validity (Predictive/Concurrent):

Not Established.

Construct Validity (Convergent/Discriminant):

Not Established.

Content Validity:

Not Established.

Face Validity:

Not Established.

Floor/Ceiling Effects:

Not Established.

Responsiveness:

Not Established.

Considerations:

• Client should have some active movemtn capacity in the involved arm
• All three shortened versions of the CAHAI-13 demonstrated strong psychometric properties and can be used as a functional measure for assessment for UE function (especially with limited time and resources). The CAHAI-7 maintained the highest level of longitudinal validity and cross-sectional validity.
• CAHAI is inexpensive and transportable compared to the ARAT. Whereas the ARAT bilaterally examines upper limb function, the CAHAI takes a bilateral approach to analyzing basic functional tasks.
