The increasing prevalence of musculoskeletal disorders necessitates the development precise and user-friendly tools in physiotherapy to improve rehabilitation outcomes. Traditional methods for determining Angle Pull (AOP) locating resistance points clinical settings often lack accuracy accessibility. To address this issue, study introduces Assist (A²) device, aimed at enhancing precision effectiveness exercises by accurately identifying point where line pull generates maximal muscle torque. primary objective research was design develop a prototype an AOP resistor locator equipped with angle reading display, reducing time required determine pinpoint least 10%. methodology involved integration MPU6050 sensor, OLED laser pointers, all controlled customized firmware. device subjected series tests, including accuracy, reliability improvement test. results demonstrate that A² achieves high R² value 0.9991 when compared true angles. Additionally, exceeded initial 16.92%. In conclusion, represents significant advancement practices providing measurements improving placement.
