Description

[0001] The present invention relates to a walking balance analysis system using a masticatory muscle exerciser,

The present invention relates to a system for analyzing a walking balance, and more particularly, to a system for analyzing a walking balance using masticatory muscles, The present invention relates to a walking balance analysis system using a fitness instrument.

It is called malalignment syndrome when the human body is not aligned and the balance between right and left is distorted. The imbalance of the human body can cause pain in our body.

It is especially important for muscles, bones, and joints.

The joints, bones, and joints are connected to each other in a continuous manner, so that deformation and loss of function of one joint will directly affect the joints.

The loss of function of these joints leads to erroneous movements, and erroneous movements create a vicious circle that causes body imbalance.

Since our body is in a chain structure, proper alignment is important in musculoskeletal disorders.

The use of computers, laptops, and smart phones in a bad posture for long periods of time increases body imbalance and causes pelvic deformity, leg length difference, difference in right and left shoulder height, deformity of the cervical spine, lumbar spine, and scoliosis do.

This imbalance actually causes a variety of pain such as back pain, headache, headache, shoulder pain, and back pain.

And it can not evenly distribute the pressure to the joints due to the deformation of the center of gravity of the body, making the degenerative changes of the joints, and various symptoms such as the blood circulation disorder and the nervous system diseases are caused due to the bad posture.

In particular, spinal alignment, which is an important nerve passage connecting the brain and the human body, affects the internal organs and causes loss of function of joints and muscles.

Furthermore, temporomandibular joint disorders affect the muscles of the neck 1 and 2 and the back of the head just below the skull, and the sub-alignment of the upper vertebrae affects the lower vertebrae again as a result, affecting the entire vertebra.

When the back of the neck impacts on the spine, and the pelvis is twisted, the alignment of the knee and ankle is distorted, resulting in a systemic imbalance.

In addition, ankle pain (AKP), such as ankle pain due to anomalies of the patella movement when the knee is flexed or unfolded due to imbalance between muscles, affects the gait pattern due to pain in the lower extremity.

Such a gait pattern may deviate from a normal gait pattern, and may require a change in a normal gait pattern because excessive force is exerted on a specific joint, or a problem occurs in a specific muscle.

Methods that can change the gait pattern include surgical method including surgery and rehabilitation method.

In addition, methods of using rehabilitation can be categorized into exercise therapy, frequency therapy, and therapy using a device. Exercise therapy or frequency therapy requires the treatment of a physical therapist, so patients have to visit a medical institution. On the other hand, there is an advantage that the treatment using the apparatus can be spontaneously treated without any time and space constraints.

There is a direct rehabilitation method that applies a physical force to the lower limb, such as a joint rehabilitation exercise device, to induce a change in the gait patterns and balance of the lower limbs, and applying a mechanism to other parts causes a change in gait pattern and balance There is an indirect way.

In the indirect method, there is no resistance exercise or irritation in the lower limbs, and the patient has a smaller binding force than other methods.

Temporo-Mandibular Joint (TMJ) is the site where the gait pattern can be changed without using the direct method.

Temporo-Mandibular Joint (TMJ) is a synovial joint between the condyles of the mandible and the temporal bone of the skull. It is a complex joint that affects other joints.

This complex joint and anatomical structure allows the TMJ to interact with the larynx muscles and cervical vertebrae, which interact with the lumbar muscle supporting the vertebrae.

Therefore, when an imbalance of body balance or abnormal gait pattern occurs, artificial deformation of the TMJ joints follows the pelvis, lumbar spine and cervical vertebrae.

Conversely, correction of the TMJ can lead to body balance and gait patterns.

One of the ways to induce deformation in TMJ is to use TMJ orthodontic device. When TMJ orthodontic appliance is applied, the occlusal plane can be aligned and this leads to the balance between the occipital bone and the upper cervical spine.

In the case of suboccipitals, about 36 spindles per 1g of muscle spindle that detect stretch reflex can be balanced to balance the skull, so that the balance of the whole body can be maintained through the correcting device.

  If the right jaw joint is closed due to the problem of the jaw joint due to right unilateral chewing, the right condyle process will move backwards and the right temporal bone will have external rotation.

This causes tension on the SCM and causes the posterior rotation of the right clavicle causing tension on the deltoid muscle and pectoralis major muscle and turning the right humerus inward.

This leads to tension of the biceps brachialis and moves the radius forward.

In addition, due to the problem of temporal bone, the right side of the sphenoid bone moves upward and the right side torsion occurs. The pharyngeal and sulcus muscles, middle fascia and deep fascia cause tension of the diaphragm and abdominal muscles.

When the right TMJ disk space stenosis occurs, the neck is rotated to the left with the left lower larynx and sternocleidomastoid muscle tilted. When the cervical spine 1 and 2 are rotated to the right, the lumbar spine is rotated to the fourth and fifth right (based on the principle of Lovett Reactor) do.

The left lower pelvis and lower pelvis are tilted upward and downward, while the left and lower pelvic limbs are tilted, so that the ankle is SUPINATION and the right is PRONATION. At this time, the right sacrum is moved backward and downward.

The right iliac bone is relatively moved upwards, and the right femur, mid-maxilla, somatosensus, and adductor muscles shorten the forward movement of the femur and tibia, resulting in internal rotation.

This creates an abnormality in the gait pattern.

This imbalance can be caused by the problem of the jaw joint, and conversely, this imbalance can be corrected through the balance of the jaw joint.

In this situation, it is not necessary to develop an accurate analysis system to check whether the effect of masticatory muscle movement actually affects the improvement of walking balance.

The improvement effect by the balance maintenance (PLST) and the improvement effect by the gait pattern according to the effect of improving the foot pressure according to the bite force correction through the masticatory exercise device (10) were confirmed as in Experimental Examples 1 and 2.

≪ Experimental Example 1 >

The One Leg Stance Balance test (OLST), which balances one leg with a leg, was performed using the masticatory exercise device 10 of the present invention. The OLST was performed again after wearing the masticatory exercise device 10 of the present invention. This process was repeated 2-3 times until OLST results were stable.

An optical motion analyzer (Optitrack, Natural Point, USA) was used to measure the balance through OLST. As shown in FIG. 4, four markers were attached to LASI, RASI, LPSI and RPSI.

The measurement was carried out until the subject could no longer maintain the balance while holding his or her arms and turning both feet and closing the eyes. The experiment was carried out four times before and after wearing the masticatory muscles (10). Stability was calculated by calculating the Pelvis Center corresponding to the center point of the four markers when standing with one leg, and calculating the center point in the Anterior / Posterior direction, Medial / Lateral direction, (vertical direction).

The pelvic center points were calculated from the four markers attached to the subject's pelvis, and the standard deviation of the pelvic center was calculated. The experimental results are shown in Table 1 and Fig. 5, and the moving standard deviation of 5.76 mm in the anteroposterior direction, 4.16 mm in the horizontal direction and 1.89 mm in the vertical direction was measured before wearing the exercise machine. On the other hand, a standard deviation of 4.20 mm in the anteroposterior direction, 2.69 mm in the left and right direction, and 1.55 mm in the up and down direction was measured after wearing the exercise machine.

When the standard deviation value is measured in all directions after wearing the masticatory exercise device (10), it means that the tremor is small while holding one leg. This means that the stability when standing with one leg is increased, It can be seen that there is an improved effect.

Values for the degree of movement before and after the action, left, right, and up and down Standard Deviation Before Wear After wearing Forward and backward direction 5.76mm 4.20mm Lateral direction 4.17mm 2.69mm Up and down direction 1.89mm 1.55 mm

<Experimental Example 2> The degree of improvement by the results of the walking pattern before and after wearing

An optical motion analyzer (Optitrack, Natural Point, USA) was used to measure the change in gait pattern before and after wearing the masticatory exercise device 10 of the present invention. As shown in FIG. 6, the marker position for the gait measurement is a total of 16 markers including LASI, RASI, LPSI, RPSI, LTHI, RTHI, LKNE, RKNE, LTIB, RTIB, LANK, RANK, LTOE, RTOE, LHEE and RHEE Respectively.

The walking test allowed more than 5m to walk for maximum natural walking. Three times of walking before exercise and 3 times of walking after exercising were performed and from the measured marker data, one cycle from the heel strike to the next heel strike was performed. , The knee (Knee), and the ankle (Ankle). Based on the calculated angles, the measured data of the subjects were compared within the normal range of flection / extension angles without obstacles to the joints.

Statistical analysis was carried out using SPSS 14, and t-test was performed in the range of confidence P <0.05 to analyze the changes in gait pattern before and after correction.

In order to facilitate the comparison of the gait test results, the range of the joint angle of the normal person and the measured joint angle before and after wearing the masticatory exercise apparatus are shown in a single graph.

The change in hip joint angle is shown in Fig. 5 (a).

Hip joint angle values were not within the range of normal persons represented by gray dotted lines, but the angular values decreased at about 40-60% of walking time compared to before wearing.

The change in hip joint angle before and after wearing the masticatory muscle was statistically significant (p <0.001).

The change in the Knee joint angle is shown in Fig. 5 (b). Changes in the masticatory muscles were observed before and after wearing the 0 to 60% corresponding to the stance phase.

The change in knee joint angle before and after wearing the masticatory muscle was statistically significant (p <0.001).

The change in Ankle joint angle is shown in Fig. 5 (c). Ankle joint angle changes before and after wearing masticatory muscles showed a statistically significant difference (p <0.001).

In other words, the wear pattern of the masticatory muscles could not change the subject's gait pattern to the range of normal persons, but the pattern of the graph changes to the range of normal persons when compared with that before wearing the masticatory muscles, The effect was more pronounced.

Since the stance phase is the point where the weight load is applied to each joint, the improvement of the joint angle in this section can be utilized as a way to alleviate pain during rehabilitation.

The gait experiment showed that the angles of the hips, knees, and ankle were shifted toward the normal range when compared to before wearing, In the induced stance phase, we moved to the normal pattern.

And an electronic pressure regulating valve 13c for regulating the fluid pressure provided on the piping connecting the supply tank 13b and the actuator 13a may be provided.

A valve operation control unit 61 electrically connected to the pressure control valve 13c to control the operation of the pressure control valve 13c as shown in the figure, And a receiving unit 62 receiving the valve operation signal from the valve control unit 61 and providing the valve operation signal to the valve operation control unit 61.

The analysis server 50 includes a transmission unit 59 for transmitting a signal to the reception unit 62 of the pressure control module 60 while being electrically connected to the central control unit 52, And a pressure analysis unit 58 for analyzing the analyzed data in the counting data analysis unit 57 and analyzing the pressure magnitude to be transmitted to the valve operation control unit 61.

In this case, when the user does not improve the difference of the foot pressure despite the normal training of the masticatory muscles through the masticatory muscle exercise or when the occlusion is not normalized despite the continuous masticatory muscle exercise, The central control unit 52 causes the pressure analysis unit 58 to start operating.

The pressure analyzer 58 analyzes the difference between the left and right occlusal forces and analyzes the pressure difference to provide the same to the central controller 52. The central controller 52 controls the pressure adjusting module 60 The pressure regulating module 60 performs valve operation control so that more resistance is generated in the masticatory movement.

That is, the training intensity is increased.
