Abstract: Sling exercise therapy has been used for active exercise therapy fields. However, a rehabilitation therapy using the sling exercise has limits from pain and reluctance. To solve the problems of the sling exercise for a therapy, we propose a sling exercise system using sonic wave vibration. The proposed system is composed of two parts, a sling machine using Sonic Wave Vibration (SM-SWV) for adjusting precisely frequency and intensity and a mobile Application (App.) for Managing the Sling Machine (MA-SM). The SM-SWV is implemented for adjusting precisely frequency and intensity according to various physical conditions of users. The MA-SM is used for controlling the proposed sling machine and connected to the sling machine via. Bluetooth Serial Port Profile (SPP). In the proposed sling exercise system, the proposed exercise mode classifies various symptoms of the patients who require treatment of muscle skeletal rehabilitation into four categories. Four types of sling exercise modes are as follows, open kinetic chain mode, closed kinetic chain mode, functional instability mode and functional movement mode. The four sling exercise modes are designed to enable various treatments to be applied depending on the symptom of the patients who require the rehabilitation of the skeletal system. Also, the proposed sling machine supports the free management mode for setting directly control items such as exercise modes, execution time and repetition time. It is necessary to manage appropriately the rehabilitation training program according to the patient’s state. In the implementation results, the user interface of the MA-SM is designed to select freely patient information, four types of exercise mode and execution time. Based on the control information transmitted from the MA-SM it is observed that the SM-SWV generates waveforms with various frequencies and intensities. It is expected that the proposed sling exercise system could provide appropriate rehabilitation programs according to patient status.
