Evaluation of arm and prosthetic functioning in children with a congenital transverse reduction deficiency of the upper limb.
OBJECTIVE
To assess upper extremity functioning of children with unilateral transverse upper limb reduction deficiency, using standardized instruments, and to investigate their validity and reliability.


METHODS
Cross-sectional study.


METHODS
Twenty subjects aged 4-12 years; 9 prosthetic users and 11 non-users.


METHODS
The Assisting Hand Assessment, Unilateral Below Elbow Test, Prosthetic Upper extremity Functional Index and ABILHAND-Kids were assessed in all children. Users were tested with and without their prosthesis. We compared results of users and non-users, and of users with and without their prosthesis. Validity was determined by testing hypotheses and correlations with other measures. Test-retest reliability was assessed from repeated measurements in 10 children.


RESULTS
Children with an upper limb reduction deficiency performed well on daily activities. They could use their prosthesis in 68% of the activities, but were currently using it in only 30%. Children find their prosthesis useful for specific activities, rather than for daily activities in general. The Assisting Hand Assessment and Prosthetic Upper extremity Functional Index showed best validity; test-retest reliability was good to excellent.


CONCLUSIONS
The use of standardized instruments adds relevant information on functioning of children with an upper limb reduction deficiency. We found additional support for validity and reliability of, in particular, the Assisting Hand Assessment and Prosthetic Upper extremity Functional Index.
