A new book chapter by Dr Jessie Janssen

An important component of physical therapy is to conduct assessment of a patient’s mobility including muscle strength and joint range of motion (ROM). This chapter describes the validity and reliability trials of the device to measure concentric elbow flexion and concentric knee extension on human subjects. Other possible clinical and on-field assessments are also discussed.
