Summary
The Amputee Mobility Predictor with prosthesis (AMPPro) and Timed Up and Go (TUG) test offer complementary insights into mobility for lower-limb amputation (LLA) patients. AMPPro effectively predicts fall risk, aiding personalized rehabilitation and fall prevention.
Area of Science:
- Rehabilitation Medicine
- Prosthetics and Orthotics
- Gerontology and Geriatric Medicine
Background:
- Lower-limb amputation (LLA) significantly impairs mobility, independence, and quality of life.
- Effective assessment tools are crucial for evaluating functional capacity, guiding prosthetic prescription, and identifying fall risks in LLA populations.
- The Amputee Mobility Predictor with prosthesis (AMPPro) and Timed Up and Go (TUG) test are common performance-based measures, but their combined use in Jordanian LLA patients is understudied.
Purpose of the Study:
- To assess functional mobility in lower-limb prosthetic users using AMPPro and TUG.
- To investigate associations between functional mobility and demographic/clinical factors.
- To determine the predictive value of AMPPro for fall risk in this population.
Main Methods:
- A cross-sectional observational study involving 63 adults with unilateral LLA.
- Participants underwent assessment using AMPPro and TUG, with collection of demographic and clinical data.
- Statistical analyses included correlations, non-parametric tests, and multivariable regression.
Main Results:
- A strong inverse correlation was found between AMPPro and TUG scores (ρ = -0.603, p < 0.001).
- Age and amputation etiology significantly impacted functional outcomes.
- Higher AMPPro scores were associated with a reduced fall risk (OR = 0.83, p = 0.004).
Conclusions:
- AMPPro and TUG provide complementary functional mobility assessments for lower-limb prosthetic users.
- AMPPro is effective in differentiating functional levels and predicting fall risk.
- Integrating AMPPro with clinical data supports individualized rehabilitation and fall-prevention strategies for LLA patients.
