Enhancing Motor Function in Individuals with Lower Limb Amputation Through Peer-Based Balance and Fall Recovery Skill Training
University of Nevada, Las Vegas
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.
Description
Objective/Hypothesis: The overall objective of this project is to investigate the clinical scientific bases of peer observation sensori-motor skill training in individuals with lower limb amputation. The general hypothesis is that participants observing models who share the same levels of amputation with them (i.e. amputee peers) will exhibit traits of enhanced motor learning when compared to observing non-amputee models. Knowledge gained from this study will directly benefit the development of more effective rehabilitation protocols and has the potential to fundamentally transform the clinica…

Interventions
- BehavioralBalance and fall recovery training
Following the video observation described in the arms, participants will undergo training to physically practice the motor tasks. The training will take place over a 2-week period encompassing 40 practice trials for each task over the training sessions. During training, the investigators will continuously monitor the changes in balance and fall recovery task performance, and will provide feedback. Participants can request to re-watch the demonstration video that they were assigned to at any time.
