The Assisting Hand Assessment Certification

The Assisting Hand Assessment (AHA) is now a well-established and frequently used evaluative tool to measure how effectively children with unilateral hand dysfunction actually use their involved hand collaboratively with their well-functioning hand to perform bimanual tasks. For the child the AHA is an enjoyable 10 to 15 minute semi-structured play session using a test-kit of selected toys requiring bimanual use. The AHA is then scored from structured video recordings of the observable performance skills during this play. The AHA measurement contains twenty items scored on a four-point rating scale. The outcome is an evaluative interval level measure, which together with the individual child’s response profile, can guide intervention.  AHA is a standardized test intended for children with unilateral Cerebral Palsy or Brachial Plexus Palsy between the ages of 18 months and 12 years. A teenage- and adult version is currently being developed.

Validity and reliability of the AHA scores are well documented in several studies. The AHA has been used as the principal outcome measure in several studies e.g. in studies evaluating Constraint Induced Movement Therapy, and has demonstrated evidence of responsiveness to change. With the AHA also longitudinal development of hand function has been studied.  Welcome to visit the web site for more information.

The course teaches the Assisting Hand Assessment Version 5.0. It is conducted in two steps. First, a 2½-day training course is given including information about the test construct, testing procedure and scoring practice on a range of children from videos. A manual with detailed scoring criteria and a computer based scoring form is provided. To achieve certification, the participant is to complete six additional cases and get satisfactory results. Some of these from videos provided on a web based e-learning platform, and some self-produced AHA play sessions. Individual feedback of these cases is provided. The AHA test kit for children between 18 months and 12 years with specific toys can be ordered from Handfast Inc, at the course or later during the certification procedure.

Course Objectives

Upon completion of this course, participants will be able to:

Demonstrate the set up, conduct and video record an Assisting Hand Assessment session and produce reliable scores according to the criteria in the manual Verbalize the concept and construct of the test and its psychometric properties Interpret and communicate the outcome of the test.
