Fig. 3A shows another embodiment of the wearable device shown in Fig. Referring to FIG. 3A, the wearable apparatus 100 is a knee protector, and can support the knee periphery region stably when a user performs a rehabilitation exercise.

The wearable device 100 shown in FIG. 3A is a two-step velcro strap system, which can maintain the fixation force in the thigh and calf region, and at the same time, the sensor can be brought into close contact with the user's skin to prevent malfunction of the device. 3A, the wearable device 100 can prevent the knee portion from shaking to the left and right by inserting the support. The wearable device 100 of FIG. 3A may have a position variable electrode portion to effectively apply a functional electrical stimulus (FES). In addition, the wearable apparatus of Fig. 3A may include a battery indicator for indicating battery status.

In the wearable device 100 of FIG. 3A, the electrodes for stimulating the electrodes and the electrodes for sensing the response to the stimulation may be arranged in the form of an electrode array. The controller can measure the EMG signal through the electrodes of the array type or select a position to transmit the EMG signal and issue a command. The wearable device 100 of FIG. 3A may include an IMU sensor, an EMG sensor, and an FES stimulator.

The IMU sensor is a sensor for detecting tilting, and knows the Euler angle composed of Roll, Pitch, Yaw, and can provide precise angle attitude data.

Fig. The electrode portion of the wearable device 100 may include a dry electrode pad that is stably attached and held on the user's skin. The electrode portion can be manufactured in the same manner using a dry high-adhesive material.

The electrode portion may collect a user's biomedical signal (e. G., An EMG signal) or deliver a muscle stimulation signal for electrical muscle stimulation (EMS) or neural dominant muscle electrical stimulation (NMES) to the user's muscles. The adhesive pad of the electrode part can be manufactured using a dry high-adhesion material to effectively obtain or transmit a user's biosignal or near-stimulus signal. For example, the electrode portion can be manufactured in the form of a conductive dry adhesive electrode pad using a non-metallic material (carbon nanomaterial).

In FIG. 3B, although the electrode portion is formed in a rectangular shape, the electrode portion may be formed in a different shape such as a circular shape or an elliptical shape without being limited thereto. Further, as shown in FIG. 3B, the adhesive pad of the electrode part has a thin sheet shape and a mushroom-shaped fine cilia structure, and thus the adhesive pad of the electrode part is largely affected by various skin conditions and environment (skin type with sweat or water, It can be stuck to the skin stably without being affected.

Since the adhesive pad of the electrode portion is a flexible conductive structure, it can maintain the adhesive force and the electric characteristic even in a physical deformation or wet environment, so that the living body signal can be measured stably even in the water or in the water.

Referring to FIG. 3C, the reel-like electrode unit can be accommodated in the slots of the bands 111 and 121 or the supports (see FIG. 2A, 110 and 120). And in use the reel-type electrode portion can be attached to the desired skin adhesion site within the maximum extent that the reel can extend from the slot. A reel of the reel-type electrode unit is wound with a wire, and a biosignal or a near-stimulus signal can be transmitted through the electric wire. The reel-type electrode unit shown in FIG. 3C is stored in the slot and the electric wires are arranged in a reel-like manner, so that it can be easily stored and used conveniently.

As described above, the rehabilitation system 10 according to the embodiment of the present invention may include a wearable device 100 implemented in various forms in terms of hardware. In addition, the electrode portion of the wearable device 100 may be realized in various ways such as a large-sized support electrode portion including a hinge, an array electrode portion, an adhesive pad electrode portion, and a reel-type electrode portion.

The rehabilitation system 10 according to the embodiment of the present invention realizes an electrode part of the wearable device 100 in an array or a reel shape so that a user-customized stimulation pattern (or waveform) and an optimum stimulation position can be found. Rehabilitation system 10 may include a program or software capable of performing a customized process.

The rehabilitation system 10 according to the embodiment of the present invention can find a stimulus position suitable for a user, set a parameter in which an optimal functional reaction occurs, and provide a user-customized recommended rehabilitation program. The rehabilitation system 10 of the present invention can be performed in the following steps.

First, the rehabilitation system 10 can find the location of the optimized stimulus for each user by changing the stimulus position until a set functional response (e.g., joint angle or muscle activity) is obtained. Secondly, the rehabilitation system 10 may change parameters such as Amplitude, Pulse per Seconds, Pulse Interval, Ramp, and Total Time, And a parameter in which a reaction (for example, joint angle or muscle activity) is generated can be set. Third, the rehabilitation system 10 may perform a customized rehabilitation exercise based on the optimized electrode position and parameters.

By way of example, the rehabilitation system 10 according to an embodiment of the present invention can perform the joint angle recovery motion by measuring the ROM of the leg. The rehabilitation system 10 according to the present invention effectively applies the electric stimulation when the leg range is below the reference range or provides the user-customized rehabilitation exercise program, so that the joint angular recovery exercise can be performed effectively.

In addition, the rehabilitation system 10 of the present invention can perform isometric exercises by measuring EMG. The rehabilitation system 10 can measure muscle activity for a certain period of time that allows the user to apply force to the leg muscles. The rehabilitation system 10 may provide an electrical stimulus or provide a customized rehabilitation exercise program when the muscle activity of the isometric exercise is below baseline.

FIG. 4 is a view showing an exemplary waveform of a control signal of the control unit shown in FIG. 2B. Figure 4 will be described with reference to Figure 2b. The horizontal axis represents time and the vertical axis represents the intensity (voltage unit) of the control signal. Referring to FIG. 4, the control signal includes a first period t0 to t1, a second period t1 to t2, a third period t2 to t3, a fourth period t3 to t4, t4 to t5). The control unit 135 can generate the control signal, and the braking unit 131 can provide the braking force or cause the vibration based on the control signal.

In the first to third sections t0 to t3, the control section 135 can set the duty cycle of the control signal to 100%. If the duty cycle of the control signal is 100%, the braking unit 131 may generate braking force for braking the rotation of the first support 110 and the second support 120 in response to the control signal. At this time, the strength of the control signal and the braking force may be proportional.

Illustratively, the braking force received by the user during the first period t0 to t1 may be smaller than the braking force received by the user during the third period t2 to t3. That is, the control unit 135 may adjust the duty cycle of the control signal to 100% so that the braking unit 131 generates the braking force. Also, the control unit 135 may adjust the intensity of the control signal to adjust the intensity of the braking force.

In the fourth to fifth intervals t3 to t5, the control unit 135 can set the duty cycle of the control signal to 50%. However, the above-described 50% is merely an example, and the control unit 135 may set the duty cycle of the control signal to any value other than 100%. If the duty cycle of the control signal is less than 100%, the braking unit 131 may cause a vibration that the user can feel in response to the control signal. At this time, the frequency of the control signal and the intensity of the braking force may be proportional.

Illustratively, the intensity of the vibration received by the user during the fourth period t3 to t4 may be less than the intensity of the vibration received by the user during the fifth period t4 to t5. Also, the amplitude of the control signal and the intensity of the braking force may be proportional. That is, the control unit 135 may adjust the duty cycle of the control signal to a value less than 100% such that the braking unit 131 vibrates. In addition, the controller 135 may adjust the intensity and the frequency of the control signal to adjust the intensity of the vibration.

The wearable apparatus 100 may include a support portion, an electrode portion, a braking portion, and a control portion. The support may be in close contact with the body part of the user to support the body part.
