Individuals with scleroderma exhibit distinct grasp patterns due to hand impairments. These unique patterns differ from typical prehension and are influenced by factors like digital sores and contractures.

Area of Science:

  • Rheumatology
  • Occupational Therapy
  • Hand Function Research

Background:

  • Standard grasp patterns may not accurately describe individuals with hand impairments.
  • Scleroderma significantly affects hand function and prehension capabilities.

Purpose of the Study:

  • To qualitatively classify static grasp patterns in scleroderma-affected hands.
  • To investigate the relationship between hand impairment and grasp variations in scleroderma patients.

Main Methods:

  • Observation of 17 subjects with scleroderma grasping various objects (key, coin, glass, saucepan).
  • Analysis of grasp patterns based on finger usage, surface area contact, and joint positioning.
  • Assessment of hand impairments including range of motion, strength, skin thickening, digital ulcers, and calcium deposits.

Main Results:

  • Grasp variations were more pronounced with coins, glasses, and saucepans compared to keys.
  • Digital sores and calcium deposits were associated with difficulties in grasping specific objects.
  • The extent of finger contractures correlated with the ability to hold all tested objects.

Conclusions:

  • Scleroderma hand impairments lead to qualitative differences in grasp patterns compared to normal prehension.
  • Understanding these unique grasp patterns can aid therapists in documenting treatment progress.
  • Qualitative grasp analysis offers valuable insights for therapeutic and surgical interventions in scleroderma.
