Validity of measuring the physical activity time of elderly hemiplegics by an activity monitoring evaluation system

Abstract

[Purpose] This study assessed the validity of using the Activity Monitoring Evaluation System (A-MES), which has been developed in Japan to measure the motion of posture over time, in measurements of physical activity levels of elderly hemiplegics in their daily living by comparing the measurement results with their actual motion. [Subjects] The subject was one young elderly person with Brunnstrom recovery stage 3 of the upper and lower extremities. [Method] We measured the motions of daily living of the subject for 1200 seconds with A-MES under the direction of the examiner, and the measurement results and video records were compared to evaluate the concordance rate. [Result] There was a high concordance rate between the A-MES results and the video records. The non-concordance rates of decubitus and the sitting position were below 3% throughout the time performing the respective positions, that of gait was below 8.2%, that of wheelchair driving was below 9.8%, and that of standing was below 25.0%. [Conclusion] The results clearly demonstrate that A-MES can be used to objectively and accurately evaluate physical activities of daily living of elderly hemiplegics. © 2013 by the Society of Physical Therapy Science.
