Background:

The Bouncy Knee concept has previously benefited active amputees by improving gait symmetry and stability on slopes and uneven ground.
This technology offers a stance phase flex-extend action, enhancing natural movement during walking.

Purpose of the Study:

To evaluate the incorporation of a bouncy function into a semi-automatic knee lock design for less active amputees.
To assess the impact of this modified Bouncy Knee on gait symmetry, slope tolerance, and walking range in a pilot study.

Main Methods:

A pilot laboratory trial was conducted with six less active amputee patients.
The Bouncy Knee's function was integrated into a semi-automatic knee lock prosthesis.
Gait parameters, including symmetry, and subjective patient responses were evaluated.

Main Results:

Less active patients did not exhibit consistent changes in gait symmetry.
Patients demonstrated an improved ability to walk on slopes.
An increased walking range was observed in the study participants.
Subjective patient feedback was positive, aligning with previous findings.

Conclusions:

The adapted Bouncy Knee shows promise for enhancing mobility in less active amputees, particularly on challenging terrains like slopes.
While gait symmetry improvements were inconsistent in this group, the functional gains in walking range and slope negotiation are significant.
Further research with larger cohorts is warranted to fully elucidate the benefits of this modified prosthetic knee.
