An interactive motion-tracking system for home-based assessing and training reach-to-target tasks in stroke survivors —a preliminary study

This study aims to evaluate the reliability, validity of IRTATS, and its measurement accuracy of the range of motion (ROM). Ninety-nine stroke patients and 20 healthy adults were recruited for the study. Kinematic variables and active joint ROM (AROM) were assessed using IRTATS. The AROM was measured by a universal goniometer, and scores from multiple clinical scales concerning motor and activity capability were calculated. Although the AROMs measured by IRTATS and the goniometer did not agree, IRTATS has clinically acceptable reliability and validity. Three variables in IRTATS could discriminate the motor performance of patients and healthy subjects. IRTATS may provide a new supplement to conventional physiotherapy in the assessment of the reach-to-target ability in stroke patients.Graphical abstractSystem configuration• The system is based on an infrared camera and the adjustable marker straps as a sensor module.• It is portable and compact, and has clinically acceptable reliability and validity.• It supports audiovisual feedback, personal goal setting, and use in regions without the internet.• It can be used as an adjunct to conventional physiotherapy in the assessment of the reach-to-target ability.
