In 30 seconds
This clinical trial investigated the relationship between residual femur motion and dynamic stability in 8 individuals with transfemoral amputations during treadmill walking. The study found that greater pistoning range of motion correlated with poorer dynamic stability metrics across participants, but changes in femur motion due to socket design did not affect individual stability outcomes.
Key findings
- Greater pistoning range of motion correlated with poorer prosthetic limb mediolateral margin of stability.
- Increased mediolateral margin of stability asymmetry was associated with greater residual femur motion.
- Within-participant changes in femur motion did not correlate with changes in dynamic stability.
Why it matters
Understanding the relationship between residual femur motion and dynamic stability can inform socket design and rehabilitation strategies for individuals with transfemoral amputations, potentially impacting fall risk and mobility.
