The hand detection unit 250 is for detecting a change in the size of a hand, and may be a camera. In this case, the hand detection unit 250 may collect changes in the size of the hand at predetermined time intervals. For example, when a hand is inserted into the rehabilitation training auxiliary case 200, the hand detection unit 250 measures the size of the hand by sensing it, and then collects the change in the size of the hand at intervals of 5 seconds. In this case, a period of photographing and collecting changes in the size of the hand may be set in advance. On the other hand, the temperature control unit 220 may adjust the temperature of the resistance member 210 by adjusting the temperature when the change in the size of the hand collected by the hand detection unit 250 exceeds a preset threshold. For example, a user with paralysis on one side may generally be accompanied by edema. When moving for rehabilitation of a body with paralysis on one side, swelling may occur in the moved body and the size may change. At this time, the hand detection unit 250 collects the change in the size of the edema at regular time intervals, and the temperature control unit 220 adjusts the temperature when the size change of the collected hand exceeds a preset threshold by comparing it with a preset threshold.

That is, when a rehabilitation exercise game such as catching a bird is provided through the display unit 230, the user may move the pen 100 to catch a bird displayed on the display unit 230. At this time, the coordinates of the pen 100 may be displayed on the display unit 230 according to the movement of the hand, and the user may match the position of the bird displayed on the display unit 230 with the coordinates of the pen 100, A bird can be caught by pressing the pen 100 (taking the pen on the floor while holding the pen). In this way, the game execution unit 270 can process all actions as the user performs the game, and as described above, the position of the bird and the coordinates of the pen 100 coincide so that the user presses the pen 100 If you catch, you can count a certain number of points.

5 is a flowchart of a temperature control method according to a change in the size of a hand according to an embodiment of the present invention.

Referring to FIG. 5, first, the hand detection unit 250 collects a change in the size of the hand (S510). In this case, the hand detection unit 250 according to the present embodiment may be a camera. Meanwhile, since the inside of the rehabilitation training auxiliary case 200 is dark and photographing of a camera may not be possible when the hand is positioned inside, the hand detection unit 250 may be an infrared camera. In this case, it is preferable that the hand detection unit 250 collects changes in the size of the hand at regular time intervals. In general, since the edema tends to increase as the user uses the affected body, the user's hand performing rehabilitation training is photographed at regular intervals to check whether the edema is increased.

Thereafter, the temperature controller 220 determines whether the size of the collected hand exceeds the threshold value, and when the size of the collected hand exceeds the threshold value, adjusts the temperature of the resistance member 210 (S520, S530). . One of the treatment methods for edema is to maintain a constant temperature around the body where edema occurs. Accordingly, in this embodiment, when the size of the hand collected by the temperature controller 220 exceeds the threshold value, the cooling function is operated to lower the temperature of the resistance member 210. When the temperature is lowered than when the temperature is raised, there is an effect of reducing pain as well as reducing edema. On the other hand, in the present embodiment, sand is used as the resistance member 210, but the present invention is not limited thereto, and any material capable of maintaining a temperature for a certain period of time or longer is not relevant. In addition, in the present embodiment, it is described that the temperature controller 220 operates only the cooling function, but the present invention is not limited thereto, and the warming function may be operated. When the temperature control unit 220 operates the warming function to increase the temperature of the resistance member 210, the muscle of the body part where unilateral paralysis occurs due to the heat stimulation of the resistance member 210 is expanded to improve the range of motion of the joint. May be. In addition, the temperature control unit 220 determines whether the size of the collected hand exceeds the threshold value, and when the size of the collected hand exceeds the threshold value, operates the cooling function for a certain period of time and then, the warming function You can also operate.

Thereafter, the hand detection unit 250 compares the size of the hand after temperature control with the size of the hand before temperature control, and when the size of the hand after temperature control is smaller than the size of the hand before temperature control, the swelling of the hand is reduced. It is determined that the temperature control unit 220 terminates the temperature control of the resistance member 210 (S540).
