Background:
Patterns and ease of stair ambulation influence amputees' level of satisfaction with their rehabilitation, confidence level, and motivation for continued rehabilitation, demonstrating the importance of stair-ascent data for rehabilitation. However, little is known about the determinants of stair-ascent patterns in unilateral transfemoral amputees.
Objectives:
To investigate the factors affecting stair-ascent patterns in transfemoral amputees.
Study Design:
Cross-sectional survey.
Methods:
Stair-ascent patterns were evaluated using the Stair Assessment Index. We collected Stair Assessment Index data as well as demographic and clinical data (sex, age, height, mass, amputation side, reason for amputation, time since amputation, and residual limb length) from 25 transfemoral amputees.
Results:
Statistical analyses revealed that age was negatively correlated and time since amputation was positively correlated with Stair Assessment Index. In contrast, height, body mass, and residual limb lengths were not correlated with Stair Assessment Index.
Conclusion:
The results of this study suggest that in unilateral transfemoral amputee, (1) both age and time since amputation could affect stair-climbing patterns and (2) residual limb length should not be a limiting factor for stair climbing if the transfemoral amputee has a certain minimum residual limb length.
Clinical Relevance:
Rehabilitation teams should carefully consider nonmodifiable predisposing factors such as age and time since amputation. However, they may be able to carry on stair-ascent rehabilitation for transfemoral amputees disregarding residual limb length (depending on the length).
