Dynamic Analysis of Elbow Joint in the Stroke of Tennis

Abstract

The paper presents a multi-rigid model of arm for an impact between a tennis ball and racket, and makes dynamic analysis of it. The input to the model is the impact force caused by a tennis ball and racket. Its value comes from the deflection of the racket stringbed detected by a high speed camera and the stiffness of the racket stringbed is measured by a force gage. The effect of the impact force on the elbow is analyzed in order to research the pathogenesis of tennis elbow.
