Design And Development Of Force Measuring Device For Push And Pull For Upper Body Extremity In Rehabilitation Therapy

Abstract

Stroke patients usually experience difficulties in exercising as a result of circumstances that make it difficult to move. So, this problem can be solved by a design tool that can facilitate patients improving muscle strength and getting to know the force applied to a movement. In addition, this project is intended to build and create a tool to measure the forces that cause someone to suffer disabilities at the top of their body. The design has two important parts: mechanical parts and electronic parts to complete construction. The mechanical parts are designed by looking at the most appropriate size to implement push and pull exercises. In addition, the materials used to build the mechanical parts are necessary in accordance with the environmental conditions and the patient's condition and convenient to carry anywhere. The use of PVC material is most suitable, as PVC is resilient to heat, light, and ductility. To design the mechanical parts, SolidWork software is used, and the analysis of the mechanical parts is done using ANSYS software. In addition, the design of mechanical parts also needs to refer to the appropriate patient's condition during the push and pull exercises. The construction of the electronics will display the value of force (N) that was exerted by the patients. By using ISIS software, the development of the circuit is more accurate, orderly, and suitable for the mechanical side when the two main parts are combined to produce a device that measures the force after a push and pull exercise is done. The use of a microcontroller in the circuit facilitates the creation of measuring tools. The combination of all parts can make the LCD display the force (N) exerted after the push and pull exercise is done. In conclusion, all the movements are to identify the force exerted, apart from improving muscle strength after exercise push and pull.
