Enhancing Motor Function in Individuals with Lower Limb Amputation Through Peer-Based Balance and Fall Recovery Skill Training

Intervention Type: Behavioral
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY

The overall goal of this research project is to investigate the effectiveness and the science of peer-based prosthetic skill training in individuals with leg amputation. Our belief is that amputee learners will show improved skill learning when observing demonstrations from other amputees, as opposed to observing nonamputee models. The investigators will accomplish the objective by answering the following two questions: Question 1: Does peer-based observation training works better for learning motor tasks for individuals with lower limb amputation (LLA)? Question 2: Are there differences in visual focus, behavior, and brain activation patterns when observing motor task demonstrations from amputee peers vs. non-amputees? Participants of this study will be asked to learn a balance and a fall recovery task by observing video demonstrations by amputee peers vs. non-amputees. The investigators will compare which setting produce better learning.

Treatments
Experimental: Amputee peers
This research uses a cross-over design to expose the participants with lower limb loss to the two training conditions (observing amputee peers vs. non-amputees) in random order, with a 4-week washout period between conditions. In this arm, participants are instructed to learn from video demonstrations by amputee peers. The videos will show balance and fall recovery movement tasks performed by the models, 15-30 seconds in length. The instruction to the participants is: Please watch and learn the tasks as performed by the demonstrator. You (the participant) will be asked to perform these tasks later.
Experimental: Non-amputees
In this arm, participants with lower limb loss are instructed to learn from video demonstrations by non-amputees. The videos will show balance and fall recovery movement tasks performed by the models, 15-30 seconds in length. The instruction to the participants is: Please watch and learn the tasks as performed by the demonstrator. You (the participant) will be asked to perform these tasks later.
