Post-Stroke Range of Motion Measurement Tool with Black Box Boundary Value Analysis Testing

Abstract

Stroke is the second cause of death and the third cause of disability in the world. One of the treatments for post-stroke patients is physiotherapy. This treatment is expensive and requires mobility. Additionally, the level of adherence of post-stroke patients in carrying out physiotherapy also influences the effectiveness of healing. Therefore, this research proposes a new tool - named “the Post-Stroke Range of Motion (ROM) Measurement Tool with Black Box Boundary Value Analysis Testing – for physiotherapy telemonitoring of post stroke patients. This tool is designed on the left hand for measuring the ROM with the integration of MPU6050, MAX30102, and Flex sensors connected to ESP WROOM 32. This study uses a quantitative research type with a laboratory and field experimental method approach. The flex sensor was tested by measuring the minimum and maximum resistance values, which are converted into straight (0<11), bending (11<46), and fully bending (46<90), and the software was tested using the Black Box Boundary Value Analysis method. The outcomes unveil that the proposed system - with its various features - has the potential to be widely applied, and readily utilized by patients in physiotherapy rehabilitation exercise at home.
