Description

Vibration type physical therapy device

This creation is about a vibrating device that can achieve muscle contraction at the right time point to induce muscle spasm in the patient's tendon injury.

At present, when a person's tendon is injured in the foot, if it is injured, the main muscle group that controls the walking movement will cause difficulty and inconvenience in walking. The main muscle group that controls the walking movement includes the triceps, gastrocnemius, soleus and tibia muscles, which all affect the walking movement.

The analysis is based on the gait cycle of the human body while walking, as shown in the sixth figure. The so-called gait cycle refers to a periodic movement from the heel of one foot to the ground to the next foot of the same foot. Each gait cycle can be divided into two phases, the standing period (St) and the swing period (Sw). The stance period (St) accounts for 60% of the entire gait cycle, starting with the heel contacting the ground and ending at the toe off the ground. The swing period (Sw) refers to the fact that the toe leaves the ground and ends at the heel to contact the ground again. This phase accounts for 40% of the gait cycle. As shown in the seventh figure, the standing period (St) of the gait cycle can be further subdivided into an initial period (IC), a load-bearing reaction period (LR), a middle standing period (MSt), a standing end period (TSt), and a pre-swing period ( PSw). The swing period (Sw) can be subdivided into the initial swing (ISw), the middle swing (MSw) and the end of the swing (TSw).

As shown in Figure 7, in a complete gait cycle, if no symptoms appear, each step should be smooth and continuous. However, if a tendon is injured in the foot, it will make the tendon unable to contract the normal muscle, which will affect walking and exercise. For example, under normal conditions, the uninjured tibia muscle (including the long tibia (A) and the short tibia (B)) will produce muscle contraction during the gait cycle (MSt) and the end of the stance (TSt), so the humerus If the muscle is injured in one day, it will not be able to produce normal muscle contraction during the middle of the stance (MSt) and at the end of the stance (TSt). Therefore, patients with tendon injuries must be physically treated and rehabilitated to prevent the lack of movement or movement of the sacral muscles to cause atrophy and avoid permanent damage.

Therefore, as for the invention of the invention of the invention of the low-frequency electric shock device for foot massage disclosed in the Republic of China on July 16, 1993, it is disclosed that it is designed for the bottom of the human foot and is a group or More than one set of positive and negative points are arranged in parallel or in series on a copper foil plate, a conductive rubber or a conductive film to form an electro-active piece, so that the electro-active piece can be distributed according to the acupuncture points at the bottom of the human foot. More than one set of positive and negative points, the electro-active piece can be implemented as an insole of a shoe, and a controller can be used to control the positive and negative points of any one or more groups to achieve massage with a low-frequency electric shock. The fitness effect of the foot acupuncture points.

However, the patent case can only use low-cycle current to stimulate the foot acupuncture point to achieve the effect of fitness. It does not cooperate with the gait cycle to cause muscle contraction and achieve physical therapy. Although the intensity of the enhanced current may still induce muscle contraction, there is a risk of electric shock to the human body. Moreover, the technical means of stimulating muscle contraction by electric current and inducing muscle contraction by vibration in this creation are completely different.

In addition, there is a patent application No. I403313 of the Republic of China on August 1, 102, "Control System for Power-Assisted Prosthetic Structure", which discloses: a measurement module and an arithmetic control circuit. The measuring module is configured to sense at least one myoelectric signal and at least one sole pressure signal, and the arithmetic control circuit is coupled to the measuring module and receives the myoelectric signal and the sole pressure signal. A control signal is generated according to the one-step correspondence table, and the control signal is used to control the pace of the human body structure to simulate the human body. The operation control circuit further generates a vibration control signal according to the one-step timing, and the vibration control signal is used to control a vibration element to vibrate the affected side foot. In this way, the operation control circuit generates the vibration control signal according to the one-step timing to vibrate the affected side of the user to achieve the purpose of the human body feeling compensation.

However, the patent is for the use of amputated patients and is not suitable for patients with tendon injuries. Moreover, although the patent pre-existing case discloses the use of a vibration motor, it can function as a vibration feeling when the affected side foot walks. However, the vibration motor is not used to cause muscle contraction, so the technical characteristics are completely different from the original.

Thus, in view of the current physical therapy devices, it is not possible to achieve a function of inducing muscle contraction in response to different cycle states in the gait cycle. Therefore, the present invention provides a vibration type physical therapy device which is provided with a fixing member. A vibration unit is disposed on the fixing member. A processing unit, the signal is connected to the vibration unit. An inertial detector, the signal is connected to the processing unit.

The inertial detector can be configured to detect a periodic state of the one-step period, wherein the inertial detector emits a control signal when the set period state is detected, and the processing unit receives the control signal After that, a vibration signal is emitted, and the vibration unit starts to generate vibration after receiving the vibration signal.

The mode in which the vibrating unit generates vibration is matched with the gait cycle so that it is in a periodic state when a staped muscle is contracted, generates vibration to stimulate muscle contraction, or directly generates vibration for the injured portion.

The vibration frequency generated by the above vibration unit is fixed at 65 Hz, and an amplitude is 0.5 mm.

The inertial detector is disposed inside the vibration unit.

2. This creation can not properly produce muscle contraction during the walking or exercising period due to the current tendon injury. Therefore, this creation can match the patient's gait cycle to make it correspond. In the periodic state, the injured tendon is induced to produce muscle contraction.

3. Due to the creation of the patient when the patient walks or moves, the vibration is only stimulated to stimulate the tendon in a specific cycle state, so the use of a higher vibration frequency to induce muscle contraction activation, thereby accelerating muscle response and increasing muscle Force to reduce the chance of re-sport injury.

The board (33). The inertial detector (3) is configured to detect the period of the foot (C) that is in the gait cycle when walking or moving. This embodiment is for detecting a patient with a stapedius injury, which is in a two-cycle state such as mid-stance (MSt) and end-stage (TSt) in the gait cycle (as shown in the seventh figure). The inertial detector (3) sends a control signal when it is detected that the patient is in the set cycle state.

The processing unit (4) is fixed on the circuit board (33) or on the fixing member (1). The processing unit (4) is connected to the inertial detector (3) for receiving the control signal sent by the inertial detector (3), and then sends a vibration signal. Further, the processing unit (4) is connected to the motor (22) of the vibration unit (2), and the motor (22) of the vibration unit (2) starts to generate vibration after receiving the vibration signal. The injured tendon used to induce the foot (C) of the human body can produce muscle contraction.

When in use, as shown in the fourth figure, the fixing member (1) can be wound on the injured part of the foot (C) of the human body, and the joint of the two ends of the fixing member (1) is used ( 11) Bonding and fixing to each other (as shown in the second figure), so that the fixing member (1) and the vibration unit (2) can be correspondingly fixed to the injured portion of the tendon (C) tendon. This embodiment is fixed at the position of the stapedius muscle of the foot (C). When the foot (C) of the human body is walking or moving, as shown in the first and fifth figures, the acceleration gauge (31) and the gyroscope (32) of the inertial detector (3) are always available. The walking or moving state of the foot (C) of the human body is detected to determine that the foot (C) is in the periodic state of the gait cycle (refer to the sixth figure). Since the present embodiment is for detecting a patient with an injury of the iliac crest muscle, the inertial detector (3) is preliminarily set to detect the stapedius muscle (including the long tibia (A) and the short tibia (B)), which causes muscle contraction. The middle of standing (MSt) and the end of standing (TSt) (please refer to the seventh figure). The vertical axis coordinate in the seventh figure represents the percentage of the measured muscle EMG signal size when the muscle is contracted. This signal is used to measure the EMG signal of the subject during maximal muscle contraction before the test gait cycle, and then compare with the muscle EMG signal during the gait cycle. . Among them, N=28 and N=19 are respectively the number of people who are invited to obtain the experimental data of the test data.

When the inertial detector (3) detects that the foot (C) is walking or moving, it is in the middle of the stance (MSt) or the end of the stance (TSt) in the gait cycle, the inertial detector ( 3) A control signal is sent to the processing unit (4). After receiving the control signal sent by the inertial detector (3), the processing unit (4) will process the operation, and then send a vibration signal to the vibration unit (2), the vibration unit (2) After receiving the vibration signal, the rotating shaft (24) of the motor (22) is controlled to start to rotate, and the eccentric block (25) on the rotating shaft (24) is used to generate a rotational imbalance when rotating. The vibration unit (2) is caused to vibrate, thereby causing displacement of the injured part of the tendon (ie, the tibia muscle) of the foot (C) (as shown in the fourth figure), so that the length of the muscle is changed, thereby inducing the tendon of the patient. In the injured area, muscle contraction can be made at the right timing to achieve the effect of physical therapy.

This creation is specifically targeted at tendon injuries, such as the ankle sprain population, or a group with a history of sports injuries. In particular, the vibration unit (2) must be placed in a specific tendon injury position (as shown in the fourth figure), such as an ankle sprain, which must be placed on the long tendon of the lateral malleolus. Since the tendon is injured, it is impossible to correctly produce muscle contraction during the walking or moving period in the corresponding cycle state in the gait cycle. Therefore, it is necessary to match the gait cycle of the patient to make it in the corresponding cycle state, and induce the injury. The tendon also produces muscle contractions. Therefore, the present invention can give vibration to stimulate the tendon only when the patient walks or moves, only in a specific cycle state. For tendon vibration stimulation, a certain frequency and amplitude setting are required, and only a higher frequency and a large amplitude can induce muscle contraction activation. The goal is to speed up muscle response, increase muscle strength, reduce the chance of re-sport injury, or increase their athletic performance.
