Abstract : Motion biomechanics is of vast interest for orthopedic surgeons, physiotherapists, rehabilitation engineers, sports equipment manufacturers, and various others. The first step toward learning the biomechanics of movement is the measurement of variables which constitutes movement. Standing from a sitting posture and vice-versa is an important daily life activity and exercise module for strengthening lower limb muscles. In this article, the data acquisition system for the measurement of three important modalities describing the biomechanics of sit-to-stand (STS) task, knee flexion/extension, trunk flexion/extension, and reaction forces at the feet and seat, is presented. The proposed data acquisition system is capable of real-time data monitoring as well as recording of variables during STS activity. The recorded data can be further used to synthesize the motion and formulate control strategies for orthotic aids.
