Abstract
Observational motion analysis is an important method for evaluating impairments of patients after bone and joint surgery. For adequate motion analysis it is necessary to understand the following: relationship between impairments and mechanical stress to bone and joint; that nature of mechanical stresses does occur; the relationship between mechanical stress and alignment of extremities; and the basic information of individual diagnosis. In this study, taking into consideration the requirements noted above we investigated the construct of observational motion analysis for patients with bone and joint surgery. Within this construct, in addition to mechanical stress, alignment and basic information, it is thought that timing of joint motion, neurological mechanism of motion and locomotion of center of gravity are important, too, and also need to be well understood. Patients with bone and joint surgery have many types of impairment. So physical therapists have to perform not only routine tests and measurements but also adequate motion analysis if they are to improvement of patients' function.
