Tutorial 2 - Simulation and Analysis of a Tendon Transfer Surgery

Purpose

The purpose of this tutorial is to demonstrate how musculoskeletal models can be used to study orthopaedic surgical techniques and to illustrate how muscle moment arm, optimal muscle fiber length, and tendon slack length influence the variation of muscle force with respect to changes in joint angle.  In this tutorial, you will:

• Become familiar with a wrist model and OpenSim’s Muscle Editor

• Simulate a tendon transfer surgery

• Examine the effects of the surgery on joint moment, muscle force, and muscle moment arm

• Investigate the effect of tendon slack length on isometric muscle force
