A Monitoring system of ankle rehabilitation for paralyzed patients was successfully designed. The monitoring application on Android smartphone was made app inventor. This application uses bluetooth HC-05 as a data transmission between the ankle therapy aids and smartphone Android. A MPX5050DP sensor is used to determine the muscle condition of the paraplegic to measure the muscle strength scale and control the motor dc speed of ankle rehabilitation hardware. The virtual keys on the application are five instructions of therapeutic movement such as, dorsiflexion (20 0 ), plantarflection (45 0 ), eversion (10 0 ), inversion (10 0 ) and patterned of movement. The access time to operate the ankle rehabilitation hardware is 0.8 seconds. This application includes an alarm and a database that can be used as a monitoring system. An alarm menu serves as a reminder for patients to take therapy and database to store data readings of sensors that converted into scale and muscle pressure. A MPX55050DP sensor output is displayed on smartphone application, stored in database and the therapy results are reserved to document format. The capacity of the database corresponds to the memory on the smartphone. Based on the measurement results, the ankle therapy application on android smartphone can control the system movement of ankle therapy aids and as a monitoring system of therapy results for paralyzed patients and make easily in analyzing the condition of leg muscle strength.
IntroductionThe development of information and communication technology influences social interaction and lifestyle. One of the applications of information technology is in the field of health [1]. Nowdays, information applications that are integrated with health equipment have become researchers' interest. The existence of an Android smartphone give significant contribution to the development of information technology in making health monitoring applications [1], [2], [3], [4], [5], [6] which are portable and easy to use. [3] has made a health monitoring system intended for patients in remote areas. A very important android-based monitoring system such as heart rate, oxygen content, blood pressure has been carried out by [5]. This study focus on the Android monitoring system aplication that is used to operate the rehabilitation device.Paralysis is the condition of a person who cannot move his body or part of his body. Physiotherapy is one of the methods used to restore a paralyzed patient to its original condition. Active rehabilitation training is more important than medical care because it can improve healing of damaged tissue, increase strength, stability, and muscle activity around treatment [7], [8], [9]. There has been conducted a research on the manufacture of human arm drive aids for paralyzed patients based on android voice command, which uses voice command commands from android as the driving command [6]. Android-based monitoring system application on this therapeutic tool serves to help the process of therapy for patients with ankle paralysis auto...
