Description

Foot-ankle biofeedback device {FOOT-ANKLE BIOFEEDBACK DEVICE}

The present invention relates to a foot-ankle biofeedback device.

The human foot and leg have a form of functional connection. That is, the musculoskeletal complex including the pelvis, knee, ankle, and foot is connected to each other, so that the stability of the foot can be transmitted to the pelvis.

The foot has a metatarsal bone, which is the backbone of the toe, and an intrinsic foot muscle, or plantar muscle, connected to the toe bone or metatarsal bone. Intrinsic muscles of the foot provide a basic stabilizing function for various factors of the foot and ankle joint. In addition, the intrinsic muscles of the foot have a local stabilization function inside the foot, a dynamic support and control function, that is, a function that reacts to various ground and environments and optimizes the structural change of the foot to adhere to the ground to ensure stable grounding, and the foot It is responsible for controlling the amount and timing of muscle activation in movement so that it can respond appropriately to the situation and environment.

As an example, there is a short foot exercise in the existing case. Short foot exercise is mainly performed to strengthen the intrinsic muscles of the foot. It is particularly applied to improve foot function and arch in people with flat feet. Referring to Figure 1 A, it shows the starting posture of the short foot exercise. A towel or the like was used to perform the short foot exercise accurately. Referring to B of FIG. 1, the posture and end posture of the short foot exercise are shown. As shown, an arch should be formed while the towel is pulled and rolled.

As another example, there is an existing toe spread out exercise. Toe spreading exercise is mainly performed to strengthen the abductor muscle of the big toe among the intrinsic muscles of the foot. In particular, toe spreading exercise is applied to improve the foot structure and function of people with hallux valgus. Referring to A in FIG. 2, the toe spreading exercise starts in a position in which the toes are spread, and referring to B in FIG. Then touch the big toe, then the other toes.

As another example, as a method of measuring surface EMG during foot-ankle exercise, EMG research is being conducted only when the sole of the foot does not touch the ground as a limitation of surface EMG measurement during foot-ankle exercise. That is, the measurement is limited to the open kinematic chain. In order to prevent noise caused by surface EMG electrodes contacting the surface during foot-ankle exercises related to closed kinematic chain, changes in muscle cross-sectional area or thickness are measured using ultrasound. However, there are limitations in identifying the muscle activity of the intrinsic muscles of the foot when performing closed chain exercises such as short foot exercise and toe spread exercise, which are practiced in clinical practice. Due to these limitations, surface EMG studies related to the foot-ankle are very few, and most of them are studies on the extrinsic muscles of the foot, making it difficult to identify the exact effects of intrinsic muscle exercises.

Meanwhile, an elastic member 160 capable of being elastically deformed within a set range in the vertical direction when a load is applied may be further provided around the first pressure sensor 171, through which the pressure can be measured more easily. . However, the arrangement of the elastic member 160 is not necessarily limited to the illustrated shape, and may be changed to various positions.

In (a) of FIG. 5, the foot 10 represents a starting position. In (b) of FIG. 5, the heel is fixed to the fixed footrest 130, and the shortfoot exercise can be performed by pulling the footrest of the forefoot in the direction of the heel.

At this time, the detected pressure of the toe may be fed back to the control unit 200 so that bending of the toe does not occur. When the front and rear movable footrest 140 moves backward by a predetermined distance using the position sensor 149 and the digital caliper 180, voice information such as pass may be output.

Meanwhile, referring to FIGS. 6 and 7 , a plurality of second pressure sensors 173 may be further provided below the left and right movable footrests 150 .

In addition, the driving control unit 300 may further include an output unit 330 that outputs set audio information when the load detected by the second pressure sensor 173 is a set reference pressure.

Accordingly, during the toe spreading exercise, the left and right movable footrests 150 of the metatarsal bones of the toes can move left and right at regular intervals according to the user's command. In particular, when a left and right movement command is applied by manipulation of the input unit 310, the left and right movable scaffolds 150 may move at regular intervals in the left and right (W2) directions. At this time, the second pressure sensor 173 may detect the toe pressure and output voice information such as pass. Toe bending exercises can improve foot function by activating intrinsic muscles such as the abductors of the big toe.
