The actimeter: analyzing human functional mobility

Abstract

The actimeter is a device that measures and records gross human body movements. The data obtained from the actimeter are used to compare the body position profiles of disable-bodied individuals to those of able-bodied persons for the same occupation. The analysis of preliminary data obtained from actimeter tests indicate that the system is approximately 75% accurate. Error associated with the system was due to the undergarment suit, mercury sensors, and sampling rate. The accuracy will increase with improvements to the present system. It is concluded that the actimeter system will provide vocational rehabilitation counselors with information to enhance their evaluation process.<>
