Abstract
A video based system for recording and analyzing biomechanical data and synchronizing them with arbitrary events and activities was described. The data acquisition system incorporated a camcorder, an analog to digital frequency shift keyed modulator/demodulator (A/D FSK modem), and a series of biomechanical sensors and amplifiers. The data extraction system included a microcomputer, a computer driven videocassette recorder (VCR), and an A/D FSK modem. Inherent timing pulses in the signal recorded on the videotape are used for synchronization with analog data. The ability of these systems to record and synchronize video images and biomechanical data made it useful for ergonomic, rehabilitation or gait analysis, or sleep laboratory or athletic performance studies. The authors conclude that the data collection and extraction system described facilitates the acquisition and synchronization of field data, and may be useful in low frequency biomedical applications. Visually identifiable events in an activity may be synchronized with associated biomechanical data.
