Continuous passive ankle motion device for patient undergoing tibial distraction osteogenesis

Abstract

This paper describes the development of a portable, easy to use, and standalone Continuous Passive Motion (CPM) device for ankle which intend to reduce the workload of physiotherapist due to increased number of patients, long term of treatments with Ilizarov Ring, and inconvenience of patients to attend to physiotherapy session frequently. The main elements in constructing CPM device for ankle were discussed in two parts: hardware and software. Hardware parts include the design of mechanical structure, and the specification of motors. While software parts are the programming codes using PIC18F4520. Expected results are the functionality of CPM device with user control. © 2011 Springer-Verlag.
