The Activity Sensor Arm Pads‘ design and functionality are based on the same concept as the Activity Sensor Pad, model 76879S. The arm pads are utilized with Lafayette Instrument Company’s computerized polygraphs LX4000-S, LX5000-S, and LX6-S, and are constructed to detect subtle as well as gross movements of shoulders, forearms, and hands of the subject during a polygraph examination. The sensors, in pouch form, are placed on the chair arms and the subject’s arms rest upon them. By providing a graphic record of subject movement, the Activity Sensor Arm Pads allow the polygraph examiner to concentrate on administering the polygraph exam instead of trying to observe the subject’s movement.
