• Description:
  The development of automated analysis techniques for investigating postural stress, repetitiveness and forcefulness was considered. These analytical methods should be able to quantify the degree of repetitiveness, forcefulness, and postural stress and at the same time reduce these large quantities of data into a form which is usable by the researchers and practitioners. In synchronization with video images of the worker performing an operation, analog signals from sensors attached to the upper extremities can be digitized, coded, and recorded on tape. Interactive multimedia computer technology reduces the data and extracts biomechanical data associated with repetitive tasks for specific work elements using a computer controlled video cassette recorder. The computer then automatically extracts the kinematic data segments corresponding to the specific elements for signal processing and analysis. The use of spectral analysis for characterizing repetitive motion and postural stress was also reviewed, along with the usefulness of frequency weighted filters to assess biomechanical stress in repetitive work.
