To stimulate muscular function, it is necessary to improve the function of muscles more rapidly and to increase the effect more. To stimulate muscular atrophy and degeneration due to aging and diseases, various stimulation methods Is presented.

To this end, there has been a way for third parties to participate in training and rehabilitation, directly or indirectly exercising their own physical strength, or by directly or indirectly controlling third parties or by directly controlling them to stimulate electricity. In addition, there is a method of applying vibration as a stimulus. For example, there is a method of indirectly transmitting vibration to rehabilitation and trainee by applying vibration to the rehabilitation and exercise apparatus using a mechanical vibration generating apparatus such as a vibration stimulating apparatus, There is a method of directly applying vibration by direct control by three persons or the user, and a method using a bulky whole body vibration device that directly transmits vibration to the whole body.

However, such a method of using physical force or electric stimulation requires a third party's intervention or has a disadvantage in that it may cause side effects such as unwanted pain, burns, and shock due to the characteristics of the stimulus applied.

In addition, stimulation using vibration or a whole body vibration device requires a large space for installing a device for generating vibration, and stimulation is applied to the entire body rather than stimulation to a local area requiring stimulation, There is a disadvantage in that undesirable side effects may be caused by the transmission of vibration exceeding the allowable range.

In addition, such a conventional method has an inconvenience in terms of efficiency because it must be controlled by a third party or a user in addition to using physical force or electrical stimulation.

The control unit 40 controls the signal according to the bending, stretching, rotation, outward rotation, rotation, outer rotation, and inner rotation of the body, .

The control unit 40 receives a motion signal of the body sensed by the sensor unit 30 and detects the motion state of the body and operates the user through the specified motion state and vibration stimulus setting unit 10 To generate vibration stimulation signals such as vibration frequency, vibration intensity, and stimulus signal to be applied to local parts such as muscles and tendons to assist the atrophy, degeneration, paralysis prevention and function of the muscles according to the condition, (Micro Controller Unit), and the controller 40 includes a band-pass filter to remove noise in a signal according to movement of the body received from the sensor unit 30. [

And controls the communication unit 50 so that the communication unit 50 can transmit the movement state signal of the body to the outside.

The excitation unit 60 applies a vibration stimulus to muscles or tendons according to a vibration stimulus signal transmitted from the control unit 40. The excitation unit 60 includes a small linear actuator or a piezo actuator and is mounted on a local area of the body, A vibration is generated according to a vibration stimulus signal generated in the body, and a vibration stimulus is applied to a body part or a local part of a tendon.

According to the portable local vibration stimulating apparatus and the stimulation method of the present invention having such a configuration, the user sets the vibration stimulation condition using the vibration stimulus setting unit 10 according to a desired vibration frequency, vibration intensity, and stimulation method.

When the user determines whether or not the vibration stimulation is terminated, The controller 30 repeats the procedure from the body motion detection step to detect the body motion through the unit 30.

On the other hand, the somatosensory receptor that responds to vibrations in the body is known to experience a vibration of 40 Hz or more and to respond sensitively to vibrations in the range of 100 Hz to 300 Hz. In order to find the most sensitive vibration frequency in the range of 100Hz ~ 300Hz, the vibration threshold value in the range of 100Hz ~ 300Hz was measured.

 As a result, it was sensitive at vibration frequencies in the range of 160Hz to 250Hz, and the most sensitive vibration frequency was 190Hz. Other vibration frequencies showed higher intensity at which they began to feel vibration, and the standard deviation was larger.

The threshold value is the minimum stimulus intensity needed for a creature to respond to changes in the external environment, ie stimulation.

Therefore, the vibration frequency of 160Hz ~ 250Hz is easy to induce the response of the somatosensory receptor to improve muscle function with less power.

In addition, since the standard deviation is small, the risk of failure to induce somatic sensory receptors is low, and there is an advantage that the vibration with a strength lower than the vibration perception threshold can be reliably introduced.

At the high frequency of 250Hz, the vibrational perception threshold was drastically increased. As the frequency increased, the vibration perception threshold also increased. Therefore, it is necessary to consider the high frequency vibration, and it is desirable to consider 250 Hz which is the most sensitive among the high frequencies and the vibration threshold is rapidly increased.

Based on these results, we set the frequency of local oscillation stimulation for improving muscle function from 160Hz to 250Hz.

In addition, the intensity of vibration applied to the local The changes in the amplitude of the somatosensory evoked potential (SEP) according to the vibration stimulation conditions are as follows.

If the somatosensory evoked potentials (SEPs) according to the vibrational stimulation conditions introduced through the foreground golgan and Achilles tendon are seen in the P260 component (between about 200 and 350m / sec from the time of the stimulation) Table 2 shows.

*: p < 0.05. Non-Stimulation versus Stimulation (70-100%).

At the frequency of 180 Hz, the amplitude of the stimulus was significantly higher than that of the non-stimulus at the 85-100% intensity, and at the frequency of 190 Hz, the amplitude of the stimulus at 85, 90 and 100% Respectively.

When the vibration stimulus was injected into the Achilles tendon, the amplitude of the stimulus at 80Hz and 100Hz increased significantly at 80 ~ 100% and 80 ~ 100%, respectively.

The amplitude of SEPs - P260 component (200 ~ 350ms positive peak) was higher than that of nonstimulation (none) when the stimulus according to the vibration condition (vibration intensity, vibration frequency) (100%).

This means that the vibrating stimulus stimulates somatosensory receptors to generate evoked potentials. Also, the amplitude of the somatosensory evoked potential was significantly higher than that of the unstimulated subjects even when the subject experienced a vibratory stimulation of 80% or more in intensity under the perception of vibration. This means that the stimulation of the periocular strength can induce the evoked potential to give the effect of vibration to the human body.

The amplitude of the P260 component of the somatosensory evoked potential appeared from the intensity of 70% of the vibration threshold level when the Achilles tendon and the foreground golgan were stimulated by the local vibration, and the intensity with statistically significant amplitude increase was 80 % Strength. It can be concluded that local oscillations below the vibrational perception threshold can also affect the human body, and vibrations above the perception threshold can also be influenced. Therefore, based on these results, the intensity of the local vibration stimulus for improving muscle function is set to 75% ~ 110% of the vibration threshold value.

The local vibration stimulation effect according to the vibration frequency conditions of the vibration frequency and the vibration intensity as described above will be described below.

First, we examine the change of muscle strength according to the vibration stimulus when the foreground golgan is stimulated.

At the frequency of 180 Hz, the increase rate of muscle strength when the perception threshold (100%) and the retrograde (80%

The mean gastrocnemius was 12.2% in the medial gastrocnemius, 11.1% in the medial gastrocnemius, 11.1% in the medial gastrocnemius, 13.2% in the medial gastrocnemius, 13.2% in the medial gastrocnemius, and 8.9% %to be.

That is, when the threshold stimulus according to the vibration condition (vibration intensity, vibration frequency) was introduced into the foreground, the leg strength was significantly increased compared to the no stimulation. Even though the subjects were not able to feel the vibration, even when the vibration stimulus of 80% strength was inputted, the leg strength was significantly increased compared to the non - stimulus.

There was no significant difference in the rate of increase of muscle strength according to the vibration stimulus of the perception threshold and the backward strength. This means that the stimulation of the perineural force is effective in increasing the muscle strength, and the same results are obtained at the frequencies of 190 Hz and 250 Hz.

This result shows that influx of the vibration stimulation of the lower limb to the lower extremity muscles through the foreground golgan influences the increase of strength and helps the movement of the lower limbs (walking, running, running, sitting, clerk, climbing, etc.) You can give.

In addition, we investigate the change of muscle strength according to vibration stimulation when we stimulate Achilles tendon. At the frequency of 180Hz, when the stimulation of the Achilles tendon was percussive (100%) and reversed (80%),

At 180Hz, the staped muscle was 16% in the threshold and 6.6% in the gastrocnemius. The lateral gastrocnemius was 15.4% in the threshold value and 13.1% in the inverse gastrocnemius. The medial gastrocnemius was 16.3% in the threshold value and 10.4% in the inverse gastrocnemius. %to be.

In other words, when the threshold stimulation was applied to the Achilles tendon according to the vibration condition (vibration intensity, vibration frequency), leg strength was significantly increased compared to no stimulation. Even though the subjects were not able to feel the vibration, even when the vibration stimulus of 80% strength was inputted, the leg strength was significantly increased compared to the non - stimulus.

There was no significant difference in the rate of increase of muscle strength according to the vibration stimulus of the perception threshold and the backward strength. This means that the stimulation of the perineural force is effective in increasing the muscle strength, and the same results are obtained at the frequencies of 190 Hz and 250 Hz.

This result shows that the inflow of vibratory stimulation of the lower limb to the lower extremity muscles through the Achilles tendon affects the increase in muscle strength and helps the movement of the lower limbs (walking, running, running, sitting, climbing, climbing, etc.) You can give.

Next, we examine the change of muscle reaction time according to vibra- tion stimuli when stimulating forehead muscles.

In other words, when the threshold stimulus according to the vibration condition (vibration intensity, vibration frequency) was injected into the foreground, the response time of the lower extremity muscle decreased compared to the unstimulated state. Even when the subject received a vibration stimulus with a strength of 80%, the muscle response time of the lower limb was significantly lower than that of the non - stimulus.

There was no significant difference in the muscle response time due to the vibration stimulation of the perineural threshold and the backward strength. This means that the stimulation of the lower limb strength is effective in reducing the muscle reaction time, and the same results are obtained at the frequencies of 190 Hz and 250 Hz.

The results showed that the inflow of vibrational stimulation of the lower limb muscles to the lower extremity muscles through the foreground muscles affected the reduction of the muscle reaction time and decreased the time required for the transmission and processing of information through the root of the sensory organ central nervous system muscle .

In addition, we investigate the change of muscle reaction time according to vibration stimulus when stimulation of Achilles tendon.

In other words, when the threshold stimulation according to the vibration condition (vibration intensity, vibration frequency) was injected into the Achilles tendon, the response time of the lower extremity decreased compared to the unstimulated, showing a significant difference. Even when the subject received a vibration stimulus with a strength of 80%, the muscle response time of the lower limb was significantly lower than that of the non - stimulus.

There was no significant difference in the muscle response time due to the vibration stimulation of the perineural threshold and the backward strength. This means that the stimulation of the lower limb strength is effective in reducing the muscle reaction time, and the same results are obtained at the frequencies of 190 Hz and 250 Hz.

The results showed that the introduction of vibratory stimulation of the lower limb muscles into the lower extremity muscles through the Achilles tendon affects the reduction of the muscle reaction time and decreases the time required for the information transmission and processing through the root of the sensory organ central nervous system muscle .

As described above, the local vibration stimulation effect according to the vibration stimulus condition of the vibration frequency and the vibration intensity is as follows.

Muscle activity of Soleus, Lateral Gastrocnemius, Medial Gastrocnemius, and Tibialis Anterior was significantly higher than that of Vocal Strength Stimulation (100%) when the Achilles tendon and foreground golgan were stimulated by local vibration. (80%), but there was no statistically significant difference between the two strengths of 80% and 100%. This means that both 80% strength stimulation and 100% strength stimulation have the effect of increasing muscle activity and that the effect is the same although there is a difference in muscle activity increase between the two strengths. That is, the local oscillatory stimulation of two intensities means that the muscular activity is increased and consequently, the muscle force exerted by the muscles is increased.

When the Achilles tendon and foreground musculature were stimulated by local vibration, the muscle response time of Soleus, Lateral Gastrocnemius, Medial Gastrocnemius, Tibialis Anterior decreased. This means that the time required for communication and processing of the sensory-central nervous-musculoskeletal route is reduced, and as a result means that the movement reaction to any stimulus is accelerated.

The above two results show that the local oscillatory stimulation of the perceptual threshold intensity and the perineural stress has a positive effect on the strength and the muscle reaction time, and as a result, the walking, running, running, sitting, clerking and climbing · It can be very helpful for speed and power generation of body movements such as pulling, pushing, catching, bending, stretching, and rotating.

Taking all the above results into consideration, the influent has a frequency of 160 Hz to 250 Hz, and a vibration stimulus intensity of 75% to 110%.
