Psychometric Properties Of Standardized Balance Confidence, Fear Of Falling, And Falls-Efficacy Measures In People With Lower Limb Amputations, Jack Y. Wang, Susan W. Hunter, Ricardo Viana, Jeffrey D. Holmes, Michael Payne

Western Research Forum

Background:

In Canada, >50% of community-dwelling lower limb amputees (LLA) fall at least once each year, a rate that is almost twice that of community-dwelling older adults. While the physical consequences of falls may be readily apparent, psychological sequelae that follow may be just as, if not more, detrimental than an actual fall itself. Current measures of balance confidence show no change in LLA following discharge from rehabilitation. The limited detectable change may be due to content validity challenges of the measures as they were not developed for the unique challenges faced by LLA.

1) Review items from standardized …

Obstacle Negotiation And Dual-Tasking In People With A Unilateral Transtibial Amputation., Humberto Omana, Michael Payne, Ricardo Viana, Susan Winnifred Hunter

Western Research Forum

Background: Falls in people with a lower limb amputation (PLLAs) are common and most often occur while walking, resulting in physical and psychological consequences that adversely affect quality of life. Walking is a complex motor task requiring cognitive resources. Due to walking with a prosthesis, PLLAs report focussing on every step they take, indicating greater cognitive needs. However, cognitive resources are limited, and most of our everyday activities also involve the simultaneous performance of motor and cognitive tasks, known as dual-tasking. The inter-relationship between mobility, cognition and postural stability in PLLAs using a prosthesis is just starting to be understood. …
