Motion Analysis Tool for Diagnosis of Orthopedic Disorders

摘要

Rehabilitation after invasive surgeries of large joints is a necessary part of a convalescenceprocess. In clinical practise, the rehabilitation results and its course are assessed by the subjectiveview of the attending physician and the evaluation depends on the amount of his experience. Themodern trend is to supplement this view with measured data and metrics, which objectively assess thecourse of the convalescence process. This approach is usually implemented by measuring thepatient’s motion data and creating a computer model, which is then examined. The patient’s motion isusually recorded in form of measuring the acceleration of the limb segments, measuring the musclepotential (electromyography) or recording a video with subsequent image analysis. The goal of thiswork is to create a comprehensive system of objective assessment of the rehabilitation using patient’smotion data recording with subsequent analysis of the measured data by classification application.The motion is represented by data from accelerometers placed on flexible bands on the assessedjoints supplemented by electromyography signals of the active muscles. The paper contains a briefresearch of commercially available solutions and a description of the proposed device that will betested in clinical conditions. The device is in the development phase.
