The therapy chair for cerebral palsy sufferers is a device designed to help sufferers carry out the
therapy process. This tool consists of a control system that makes it easy for sufferers to increase the
independence of patients in operating the device. The purpose of this tool is to improve cerebral palsy therapy.
This chair uses a hydraulic system as an actuator and an Arduino as a control device. This method is applied,
namely designing, manufacturing, assembling and testing. The results of this study indicate that in the experiments
that have been conducted, it is found that to adjust the position of the therapy chair until the patient is standing
requires the lowest time in patient A is 65 seconds with the patient's body weight is 70 kg while for the highest
time, namely in patient D is 92 seconds with the patient's body weight 73 Kg. Based on the results of these tests, it
was concluded that the therapy chair with the Arduino Uno control system could make it easier for patients to
operate and streamline the time spent in the therapy process
