J Rehabil Res Dev. 2013;50(5):687–98. Slideshow Project DOI: /JRRD JSP Aim – Assess motor learning in people with lower-limb amputation using proportional myoelectric control from residual-limb muscles. Relevance – Major hurdle in developing commercially successful powered prostheses is control interface. – Myoelectric signals are one way for prosthetic users to provide feedforward volitional control of prosthesis mechanics.

J Rehabil Res Dev. 2013;50(5):687–98. Slideshow Project DOI: /JRRD JSP Method 9 individuals with transtibial amputation and 13 nondisabled controls tracked virtual object. Assessed: – How quickly individuals with amputation improved their performance. – Whether years since amputation correlated with performance.

J Rehabil Res Dev. 2013;50(5):687–98. Slideshow Project DOI: /JRRD JSP Results At beginning of training: – Subjects with amputation performed much worse than control subjects. By end of short training: – Tracking error did not significantly differ between subjects with amputation and nondisabled subjects. Initial but not final performance correlated significantly with time since amputation.

J Rehabil Res Dev. 2013;50(5):687–98. Slideshow Project DOI: /JRRD JSP Conclusion Although subjects with amputation may initially have poor volitional control of residual lower-limb muscles, training can substantially improve control. Findings are encouraging for future use of proportional myoelectric control of powered lower-limb prostheses.
