LVQ based speed adaptive swing and stance phase detection:An alternate to Foot Switch

This paper presents a novel method for stance and swing phasedetection employing Learning Vector Quantization (LVQ), usingknee angle information only. The results show detection accuracy of95.9% in stance phase and 83.9% in swing phase. The researchconcludes an efficient replacement of footswitch for phase detection.The work can directly lead to low cost speed adaptive transtibialprosthesis where the knee angle measurement can be used to decidethe damping in the prosthesis.
