Summary

Children with below-elbow amputation show delayed bimanual activities of daily living (ADL) skills. Prosthetic wear duration did not significantly correlate with these functional performance improvements.

Area of Science:

  • Pediatric rehabilitation
  • Occupational therapy
  • Prosthetics and orthotics

Background:

  • Unilateral below-elbow amputation presents unique challenges for children's development.
  • Understanding bimanual functional skill acquisition is crucial for effective intervention.

Purpose of the Study:

  • To investigate bimanual functional skill development in children with unilateral below-elbow amputation.
  • To compare their development patterns with able-bodied children.
  • To examine the relationship between prosthetic wear duration and functional performance.

Main Methods:

  • Assessed 69 children under ten with unilateral below-elbow amputation.
  • Evaluated 14 prosthesis-assisted bimanual activities of daily living (ADL).
  • Compared performance against established standards for able-bodied children.

Main Results:

  • Bimanual ADL skill development was not delayed in 5 of 14 comparisons.
  • Most development patterns exhibited multimodal, nonmonotonic profiles.
  • Prosthetic wear duration showed weak correlation (r < .52) with ADL skills.

Conclusions:

  • Below-elbow amputation impedes pediatric ADL skill development, even without central nervous system dysfunction.
  • Developmental delays are complex and not uniformly expressed across all children.
  • Delays are not solely attributable to mechanical prosthetic deficiencies.
