This paper suggests a simple yet efficient experimental method to record the displacement of the shaft in a revolute joint with clearance. Two light and compliant cantilevers have been mounted on the rocker, each being instrumented with two strain gauges which can measure bending. These cantilevers are mounted in an orthogonal fashion, near the axis of the revolute joint, each touching the shaf...

INTRODUCTION Parkinson's Disease (PD), amongst its motor symptoms, can cause dystonia of the limbs and trunk. This can lead to subsequent deformities. CASE PRESENTATION We describe a case where Parkinson's Disease has gone on to cause bilateral Charcot feet with rocker-bottom deformity. CONCLUSION There is recognised pattern of foot deformities seen in Parkinson's disease and it is importan...
