The Design and Analysis of a Human Body Motion Measurement System
Abstract
No adequate systems were found in a literature search that would permit direct measurement of human body segments' angular acceleration and muscle forces related to these accelerations which would allow application of analytic mechanics to the human motion problem. Therefore, a new system was designed and analyzed to provide accurate measurement of the body segments' motion directly by use of angular accelerometers. The basic elements of the system are the accelerometers, all electromyogram sensors, and a proportional bandwidth telemetry system that allows the human performer to move about freely. Verification of the system was accomplished by measurement of angular accelerations of the arm and leg links during kip-up maneuvers. Alignment of the accelerometers was achieved by an optical laser technique. The acceleration signals, stored on magnetic tape, were subsequently integrated to get rate and position in an inertial reference frame. These position data, obtained through integration, proved to be insufficiently accurate when compared with synchronized position data obtained from high speed motion picture film data. (Author)
