The Application of Infrared Signal to Measure Cycling Speed for Physical Therapy Department with Video Games

Abstract

          Cycling is a crucial medical device for restoring patient movement in the physical therapy department. However, reports indicate that the number of available bikes is insufficient to meet patient needs, leading to longer recovery times. This research aims to develop a cycling system that incorporates video games and infrared signals for use in the physical therapy department of a private hospital. The cycling structure measures 60 cm. x 85 cm and is controlled b an Arduino Nano board. An infrared sensor is installed to detect cycling speed, which corresponds to a VDO game on a monitor. The game has three levels, with speeds of 30, 40, and 50 rpm, respectively. The cycling system of performance was evaluated, and the results demonstrated standardization across all three levels.  The cycling speed at levels1, 2, and 3 was consistent, with tensile strengths of 540, 573, and 650 N, respectively. Additionally, the motor and infrared sensor functioned correctly during cycling, adhering to the principle of the Joint Commission International (JCI). Therefore, the cycling system meets the standard qualification requirement for use in the physical therapy department.
