Sensory-Motor Mechanisms Underlying Fall Risk in Transtibial Amputees

Detailed Summary

Lower limb prosthesis users are known to be at a substantially increased fall risk compared to able-bodied individuals. The interaction between increased fall risk, reduced balance confidence and high prevalence of a fear of falling often leads to restricted mobility and loss of independence. Critically, the cause of these falls and the role that inherent balance plays in fall risk is poorly understood. This study proposes to identify key differences in balance and mobility between older below-knee prosthesis users and able-bodied individuals. By further understanding the differences between these groups and relationships between fall risk and various outcome measures, intervention techniques can be developed to improve functional balance. An improvement in upright balance will reduce the occurrence of falls and fall related injuries in this veteran population, as well as increase their participation in daily activities and improve their quality of life.
