The Assisting Hand Assessment (AHA) is a test of hand function in children with difficulties using one of their hands. The AHA measures how effectively the affected hand and arm is used in bimanual performance. An assessment is performed by observing the child's spontaneous handling of toys in a relaxed and playful session. The scale is 0-100, and a higher score indicates better function. A change of +5 is clinically significant.

The Melbourne Assessment 2 (MA2) is a valid and reliable criterion-referenced test for evaluating four elements of upper limb movement quality in children with a neurological impairment aged 2.5 to 15 years: (i) Range of movement, (ii) Accuracy of reach and placement, (iii) Dexterity of grasp, release and manipulation and (iv) Fluency of movement.

The full test comprises 14 test items which require a child to reach to, grasp, release and manipulate simple objects. Each child's test performance is video recorded for subsequent scoring.

Scoring is completed across the 30 score items using a three, four or five point scale and individually defined scoring criteria. Item scores relating to each element of movement measured are summed within the corresponding sub-scale. A raw score scale change of 3 for range of motion, dexterity, and fluency; and a change of 4 for accuracy is considered clinically significant.

CHEQ is a newly developed questionnaire. It has been developed for children and adolescents with decreased function in one hand, for example hemiplegic CP, obstetric brachial plexus palsy (OBPP) and upper limb reduction deficiency, and for their parents. The scale is 0-100, with the higher score indicating better abilities.
