Using model hands for learning orthotic fabrication.

Area of Science:

• Rehabilitation Medicine
• Medical Education
• Orthotics and Prosthetics

Background:

• Orthotic fabrication is a key skill for trainees.
• Simulated training environments can enhance learning.
• The effectiveness of model hands for orthotic practice is not well established.

Purpose of the Study:

• To compare the effectiveness of practicing orthotic fabrication on a model hand versus a real hand.
• To evaluate the impact of practice method on orthotic quality and fabrication time.
• To assess skill transfer to a novel task.

Main Methods:

• Twenty-one participants were randomized into two groups: real hand practice or model hand practice.
• Participants practiced orthotic fabrication on their assigned hand type.
• Performance was evaluated using a validated checklist and global rating scale (GRS) during practice and a transfer test.

Main Results:

• Both groups showed significant improvement in GRS scores and reduced fabrication time over practice.
• Trainees using the model hand achieved higher final product scores on the checklist during practice and the transfer test.
• Model hand practice led to superior orthotic fabrication quality.

Conclusions:

• Practicing orthotic fabrication on a nonpathological model hand is more effective than practicing on a real hand.
• Model hands provide a valuable tool for training orthotic fabrication skills.
• Further research should explore instructional and contextual factors influencing training outcomes.
