Beneficial effect of isometric device therapy in overcoming sprain injuries in the ankle due to sports using the arduino uno pro mini and load cell device design

Abstract

This study aims to create an isometric exercise therapy tool in overcoming sprain injuries on the digital-based ankle that is valid, reliable, practical, effective and efficient. This type of research uses a Research and Development design, this research involves 3 experts who are competent in their fields, namely instrumentation physicists, exercise physiologists, and physiotherapists. A total of 30 men who were selected using the Purposive Sampling technique with ages ranging from 20 to 28 years and had sprain injuries in the ankle participated in this study. The testing of the tool was carried out using a questionnaire, test and retest. Statistical analysis of the data used is r-correlation. The results of the reliability test of the alpha coefficient, the results of the first day and the second day have a «high» correlation. The results of the product practicality test by the three experts show the product has a «very good» level of practicality, and the results of the product effectiveness test are obtained with an effectiveness level of «very good». Therefore, design an isometric therapy device for ankle sprain injuries due to sports using Arduino Uno and load cells which are effective for treating sprain injuries.
