Description

Technical Field

[0001] This invention relates to a training device, and more particularly to a training device for reducing high tension. Background Technology

[0002] Spasticity is a common symptom in patients with central nervous system injuries, often lasting a lifetime. Preliminary estimates from relevant medical institutions suggest that over 12 million people worldwide suffer from this symptom. One common treatment method involves using traction equipment to perform prolonged stretching to reduce muscle hypertonia, thereby decreasing the likelihood of spasticity. However, this method of stretching muscles to near their limits for extended periods can easily cause discomfort (such as pain, muscle strain, etc.) or pressure sores at pressure points.

[0006] Preferably, the drive module includes a motor, a transfer mechanism, two connecting rods, and two connecting wheels. The motor is connected to the transfer mechanism, the two connecting rods are connected to the transfer mechanism, and each connecting wheel abuts against one of the pedals. The control module can control the motor to rotate. When the motor rotates, it will drive the two connecting rods to rotate simultaneously through the transfer mechanism, thereby causing the two connecting wheels to rotate. Each rotating connecting wheel will drive the pedal it abuts against.

[0007] Preferably, the control module includes a processor, a memory, and a communication unit. The processor is electrically connected to the memory and the communication unit. The communication unit can receive multiple training programs transmitted by an external electronic device.

[0008] Preferably, after the control module completes the training program, the processor can generate corresponding recording information, which includes the motor speed in a training cycle, the number of swings of each pedal in a training cycle, a training time, and a training date. The processor can also transmit the recording information to an external electronic device through a communication unit.

[0009] Preferably, the drive module drives the two pedals to swing using both a same-phase operation and a different-phase operation.

[0027] In the following description, if a specific drawing is indicated or shown in a particular drawing, it is only to emphasize that most of the relevant content mentioned in the following description appears in that particular drawing, but does not limit the following description to refer only to that particular drawing.

[0028] Please refer to the following: Figures 1 to 5 The training device 100 for reducing high tension of the present invention includes: a base 1, a drive module 2, two pedals 3, a control module 4, and a switch module 5. The drive module 2 is fixedly disposed on the base 1. Each pedal 3 is connected to the base 1, and one end of each pedal 3 can swing relative to the base 1 about a rotation axis A. Each pedal 3 may be pivotally connected to the base 1 via a shaft B and a bearing assembly C, but the manner in which the pedal 3 is pivotally connected to the base 1 is not limited to that shown in the figure.

[0029] Each pedal 3 has a placement area 31 for placing one of the user's feet. Two pedals 3 are respectively connected to a drive module 2, which drives each pedal 3 to repeatedly swing relative to the base 1 between a first position and a second position. The size and shape of the pedals 3, and the shape and size of the placement area 31, can vary according to requirements; the figures shown in this embodiment are only one example.

[0030] Specifically, in one practical application, the drive module 2 may include a motor 21, a connecting mechanism 22, two connecting rods 23, and two connecting wheels 24. The motor 21 is connected to the connecting mechanism 22, and the two connecting rods 23 are also connected to the connecting mechanism 22. The other end of each connecting rod 23 is connected to a connecting wheel 24, and each connecting wheel 24 abuts against one of the pedals 3. The control module 4 can control the motor 21 to move. When the motor 21 is controlled to rotate, it will simultaneously drive the two connecting rods 23 to rotate through the connecting mechanism 22, thereby causing the two connecting wheels 24 to rotate. The rotating connecting wheels 24 will cause the pedal 3 they abut to swing relative to the base 1. In the accompanying drawings of this embodiment, each connecting wheel 24 is an eccentric cam as an example, but the form of the connecting wheel 24 is not limited to this. For example, the connecting wheel 24 can also be a plate cam. Regarding the positions where each connecting wheel 24 abuts against each pedal 3, they are roughly opposite to the end where the pedal 3 is pivotally connected to the base 1. The form and size of the connecting wheel 24 can vary according to requirements and are not limited here. That is, the swing amplitude (swing angle) of the pedal 3 is related to the form and size of the connecting wheel 24 and can vary according to requirements. In practical applications, for example, the motor 21 can be controlled to drive the connecting wheel 24 to change the initial tilt degree (initial angle) of the pedal 3. To ensure stable rotation of each connecting rod 23, the drive module 2 can also include two bearing assemblies C, with each connecting rod 23 connected to one bearing assembly C.

[0031] The control module 4 is electrically connected to the drive module 2. The control module 4 stores at least one training program and can execute the training program. When the control module 4 executes the training program, it controls the drive module 2 to move, causing the two pedals 3 to swing at least 1 to 120 times per minute in a training cycle, and the swing angle of each pedal 3 from the first position to the second position is 5 to 70 degrees.

[0032] like Figure 4 As shown, when the pedal 3 is in the first position, the angle between the plane P1 containing each placement area 31 and the horizontal plane P is defined as a first angle θ1; wherein, when the first position is the lowest position, this first angle θ1 is the initial angle; as shown Figure 5As shown, when the pedal 3 is in the second position, the angle between the plane P2 containing each placement area 31 and the horizontal plane P is defined as a second angle θ2. This second angle θ2 is at its highest point when the second position is the highest position. The first angle θ1 is smaller than the second angle θ2, and the difference between the second angle θ2 and the first angle θ1 is the swing amplitude of the pedal 3. The first angle θ1 and the second angle θ2 are related to the form and size of the connecting wheel 24; the first angle θ1 is between -5 and 5 degrees, and the second angle θ2 is between 5 and 70 degrees. In practical applications, the first angle θ1 and the second angle θ2 can be changed by altering the shape and size of the two connecting wheels 24.

[0033] In one embodiment (such as) Figure 6 As shown, each pedal 3 can be connected to a position adjustment mechanism E, which can be mounted on the base 1. This position adjustment mechanism E can change the height of one end of each pedal 3 relative to the base 1 according to the control signal from the control module 4. Alternatively, the position adjustment mechanism E can change the distance between the rotation shaft A and the base 1 according to the control signal from the control module 4, thereby changing the first included angle θ1 and the second included angle θ2. It should be noted that any mechanism that can change the first included angle θ1 and the second included angle θ2 according to the control signal from the control module 4 should fall within the scope of application of the position adjustment mechanism E.

[0034] In practical applications, control module 4 may store only a single training program, or it may store multiple training programs; there is no limitation on this. In practical applications, each training program may contain at least one training control parameter. For example, the training control parameter may include the swing speed of each pedal, the first included angle θ1, the second included angle θ2, the swing amplitude of each pedal 3, etc. In embodiments where control module 4 stores multiple training programs, when control module 4 executes different training programs, at least one of the swing speeds (i.e., the number of swings per minute) of the two pedals 3, the swing amplitudes of the two pedals 3, and the first included angle θ of the two pedals 3 may not be completely identical, but this is not a limitation.

[0035] In practical applications, a single training program may have multiple training time segments, each occupying a different proportion of the total training time. Furthermore, the number of swings, swing speed, and swing angle of the two pedals 3 may differ across these segments. For example, a single training program may contain three training time segments (5 minutes, 20 minutes, and 5 minutes). During the first 5 minutes of the training program, control module 4 may control each pedal 3 to swing 15 times per minute. During the subsequent 20 minutes, control module 4 may control each pedal 3 to swing 30 times per minute. In the final 5 minutes, control module 4 may control each pedal 3 to swing 15 times per minute. In practical applications, the motor's rotational speed and the number of swings per minute of each pedal 3 may be positively correlated. Preferably, the number of swings per minute of each pedal 3 may fall between the cadence of a normal person's slow walking and fast running.

[0036] It should be noted that in practical applications, relevant personnel can, according to requirements, make the control module 4 execute a training program so that the two pedals 3 swing in different directions respectively. That is, when one pedal 3 swings towards the base 1, the other pedal 3 swings away from the base 1. Alternatively, the two pedals 3 can swing synchronously, that is, the two pedals 3 swing towards the base 1 at the same time or swing away from the base 1 at the same time. Alternatively, the two pedals 3 can swing in the same direction with different swing amplitudes. For example, when one pedal 3 swings towards the base 1 by 1 degree, the other pedal 3 swings towards the base 1 by 3 degrees.

[0037] It should be noted that, in practical applications, the training device 100 has an operation mode in which the two pedals are driven to swing in a same phase operation mode and a different phase operation mode.

[0038] Specifically, each connecting wheel 24 can be a cam (i.e., a component with an elliptical outer contour), and each cam can have multiple locking holes (e.g., 2, 4, 6, 8, etc.). These locking holes can be arranged approximately around the center of the cam. Assemblers can connect one end of each of the two connecting rods 23 to the locking holes at different positions on adjacent cams. Thus, when the two connecting rods 23 are driven synchronously, the two pedals 3 will abut against different positions on corresponding cams, thereby achieving a phase-difference oscillation effect. In another embodiment, the connecting wheel 24 can have a polygonal hole formed eccentrically on the connecting wheel. One end of the connecting rod 23 can have a corresponding polygonal structure, and the polygonal structure of the connecting rod 23 can engage with the polygonal hole of the connecting wheel 24. Therefore, assemblers can change the engagement position of the polygonal holes of the two connecting wheels 24 with the polygonal structures of the two connecting rods 23 as needed, thereby enabling the two pedals to oscillate with a phase difference. For example, the two connecting wheels 24 can have identical structures, and each polygonal hole can be a rectangular groove. When assembling the two connecting wheels 24, the personnel can either position both polygonal holes close to the base 1, or position both polygonal holes far from the base 1. In this way, the two pedals will swing without any phase difference. Conversely, if the polygonal hole of one connecting wheel is positioned close to the base, while the polygonal hole of the other connecting wheel is positioned far from the base, the two pedals will swing with a phase difference of 180 degrees. Therefore, in different embodiments, the relevant personnel can make the two pedals swing at different phase angles by changing the shape of the polygonal holes and the polygonal holes of each connecting rod 23. For example, when the polygonal hole is square, the relevant personnel can make the phase difference between the two pedals swing 0 degrees, 90 degrees, 180 degrees or 270 degrees as needed; when the polygonal hole is regular hexagon, the relevant personnel can make the phase difference between the two pedals swing 0 degrees, 60 degrees, 120 degrees, 180 degrees, 240 degrees, 300 degrees or so as needed.

[0039] In one specific application, the control module 4 may include a processor 41, a storage unit 42, and a communication unit 43. The storage unit 42 and the communication unit 43 are electrically connected to the processor 41. The processor 41 can receive at least one training program transmitted from an external electronic device D (e.g., a smartphone, tablet computer, etc.) via the communication unit 43, either wired or wirelessly. The storage unit 42 is used to store multiple training programs. For example, a user can generate at least one training program through an application on the external electronic device D and transmit it to the control module 4.

[0040] Specifically, when relevant personnel execute an application through an external electronic device D, they can view multiple training programs currently stored in the control module 4 on the display screen of the external electronic device D. The relevant personnel can then select one of the training programs displayed on the external electronic device D based on the patient's condition, thereby controlling the control module 4 to execute the corresponding training program.

[0041] The training device 100 for reducing high tension may also include an operating interface 6, electrically connected to the processor 41. The operating interface 6 provides user operation to control the processor 41 to execute one of the training programs stored in the memory 42. That is, relevant personnel can operate the operating interface 6 to cause the control module 4 to execute a training program suitable for the patient's condition. For example, the operating interface 6 may include a display 61 and multiple buttons 62. The display 61 shows information such as the swing angle of each pedal 3 and the number of swings of each pedal 3 in each training cycle, and the control module 4 can set corresponding values ​​for the training program based on the pressed states of the multiple buttons 62. Of course, in different embodiments, the control module 4 may also include a wireless communication module, which can connect to external electronic devices (such as servers, smartphones, tablets, etc.) so that relevant personnel can control the control module 4 through the external electronic devices.

[0042] In a preferred application, after the control module 4 completes the training program, the processor 41 can generate and store the corresponding recording information in the memory 42. The recording information may include parameters of this training program (e.g., a motor speed in a training cycle, the number of swings of each pedal 3 in a training cycle, a training time) and a training date. In addition, the processor 41 can transmit the recording information to an external electronic device D or a cloud server through the communication unit 43. Relevant medical personnel can then read the patient's recording information on the external electronic device D or the cloud server to track the patient's movement status.

[0043] The control module 4 may also include a switch module 5 (e.g., a button 51) to turn the training device 100 for reducing high tension on or off. The control module 4 may also include a stop module 7. Specifically, the stop module 7 may include a button that allows the patient to quickly stop the operation of the training device 100 for reducing high tension immediately by pressing the stop module 7 in case of any discomfort or emergency while using the training device 100 for reducing high tension.

[0044] Please see Figure 7In this embodiment, each pedal 3 is also provided with a limiting structure 32, which is used to limit the range of motion of the foot placed in the placement area 31 relative to the pedal 3. In this embodiment, when the user's foot is placed in the placement area 31, the limiting structure 32 is correspondingly abutted against the user's heel, but the shape of the limiting structure 32 and its position are not limited thereto.

[0045] In one specific embodiment, the motor 21 may be, for example, a stepper motor, and the control module 4 may simultaneously determine the rotation angle of each pedal 3 relative to the base 1 while controlling the stepper motor. In another embodiment, the training device 100 for reducing high tension may further include two angle detection modules 8, each angle detection module 8 used to detect the rotation angle of each pedal 3 relative to the base 1; the angle detection modules 8 are electrically connected to the control module 4, and the control module 4 can control the swing angle of each pedal 3 from a first position to a second position according to the detection results transmitted by each angle detection module 8. Through the design of the angle detection modules 8, relevant personnel can more accurately understand the rotation angle of each pedal 3 relative to the base 1, thereby better grasping the training effect of the patient. In a better embodiment, the relevant personnel control module 4 may transmit the information detected by each angle detection module 8 to an external electronic device D, and the relevant personnel may operate the external electronic device D to calibrate the drive module 2, thereby enabling the drive module 2 to make each pedal 3 rotate more accurately to a predetermined angle. In different embodiments, the control module 4 may also be a display included in the control interface 6, displaying the information detected by each angle detection module 8, and the user can use the operation interface 6 to calibrate the drive module 2. Of course, the control module 4 may also automatically calibrate the operation of the drive module 2 based on the detection results of the two angle detection modules 8.

[0046] The training device 100 for reducing high tension in this embodiment may also include two sets of sensing modules 9. Each set of sensing modules 9 includes multiple pressure sensors 91. The multiple pressure sensors 91 of each set of sensing modules 9 are disposed on one of the pedals 3 and are located in the placement area 31. The control module 4 is electrically connected to each pressure sensor 91. The processor 41 of the control module 4 can obtain a resistance-angle reference data set corresponding to the user's calf muscles based on the pressure values ​​returned by the multiple pressure sensors 91 and the angle of each pedal 3 (the angle between the plane where the placement area 31 is located and the horizontal plane). This resistance-angle reference data set presents the pressure values ​​sensed by the pressure sensors 91 at different angles of the pedal 3 (this test is referred to as a "muscle tension test" in this invention). The processor 41 can control the display 61 to show a corresponding resistance-angle curve based on the resistance-angle reference data set, or the processor 41 can transmit the resistance-angle reference data set to an external electronic device D. After receiving the resistance-angle reference data set transmitted by the processor 41, the external electronic device D can display the corresponding resistance-angle curve on its display. The pressure value reflects the resistance of the calf muscles. Furthermore, the motor 21 can be a stepper motor, and the control module 4 can obtain the pressure value measured by each pressure sensor 91 when the motor 21 rotates by a predetermined angle (i.e., the angle between the plane where the pedal placement area 31 is located and the horizontal plane changes), and subtract the pressure value measured when the foot is placed on the stationary pedal 3 (e.g., the pressure value before swinging, or the pressure value at the initial angle) to obtain a resistance value. Thus, the control module 4 can calculate the resistance-angle curve.

[0047] As stated above, the inventors discovered that the maximum resistance value in the resistance-angle curve can be used to determine the degree of hypertonia in the user's calf muscles. The larger the maximum resistance value, the more severe the hypertonia in the user's calf muscles (i.e., the user has muscle rigidity or muscle spasm). Conversely, it means that the user's calf muscles do not have hypertonia problems.

[0048] Generally, muscle stiffness or spasms are usually caused by high tension in the muscle group. The training device of the present invention for reducing high tension can be used to test the muscle tension of the user's calf muscles to determine whether the user's calf muscles are stiff or spasming.

[0049] In one specific embodiment, the control module 4 can perform a high-tension analysis test to determine whether the user's calf muscles have stiffness or spasms. Specifically, when performing the high-tension analysis test, the control module 4 first controls the two pedals 3 to swing at a first speed and obtains a first resistance-angle data set. Then, the control module 4 controls the two pedals 3 to swing at a second speed and obtains a second resistance-angle data set. Next, the control module 4 finds the maximum resistance value from the first resistance-angle data set and divides it by the maximum resistance value in the second resistance-angle data set to obtain a comparison value. The first speed and the second speed are not the same, and the first speed can be greater than the second speed. For example, when the pedals swing at the first speed, it can swing 60 times per minute, and when the pedals swing at the second speed, it can swing 30 times per minute, for example. If the comparison value is close to 1, it indicates that the user's calf muscles may have rigidity. Conversely, the larger the difference between the comparison value and 1, the larger the difference, indicating that the user's calf muscles may have spasms. A higher comparison value indicates that more of the high tension is due to reflexive muscle spasms.

[0050] As described above, the control module 4 can first determine whether the user's calf muscles have high tension problems through a "muscle tension test" (i.e., the higher the maximum resistance value, the higher the severity of high tension). If the control module 4 determines that the user's calf muscles have high tension problems, the control module 4 will then perform a "high tension analysis test" to determine the severity of muscle stiffness or muscle spasm in the user's calf muscles.

[0051] In a preferred embodiment, when the control module 4 determines whether the user's calf muscles have high tension, it may only determine that the user's calf muscles have high tension if the maximum resistance value in the resistance-angle control data set exceeds a high tension threshold. Similarly, when the control module 4 determines whether the user's calf muscles have rigidity or spasm, it may only determine that the user's calf muscles have spasm if the calculated comparison value exceeds a predetermined threshold; if the control module 4 determines that the comparison value does not exceed the predetermined threshold, it determines that the user's calf muscles have rigidity. The high tension threshold and the predetermined threshold can be obtained, for example, through statistical analysis of a large amount of experimental data, and are not limited thereto. The aforementioned threshold values ​​may vary depending on the experimental subjects (e.g., general population, athletes, young people, or the elderly), and the training device for reducing high tension of the present invention can adjust the threshold values ​​according to different users.

[0052] Furthermore, the processor 41 of the control module 4 can perform multiple rounds of measurements to obtain multiple sets of resistance-angle data under conditions where the motor 21 rotates at high speed (e.g., 60 revolutions per minute) and slow speed (e.g., 20 revolutions per minute). It can also determine the resistance reduction at high speed in the first and last rounds (the Nth round) when the motor is at high speed, and the resistance reduction at slow speed in the first and last rounds when the motor is at slow speed. Thus, the processor 41 can derive an index that represents the degree of post-activation depression (PAD) based on the resistance reduction at high speed and the resistance reduction at slow speed.

[0053] Specifically, the processor 41 can first control the motor to rotate at a relatively slow speed so that each pedal swings a predetermined number of times. During each swing of each pedal, the processor 41 obtains the corresponding pressure value through a pressure sensor. The processor 41 can then obtain the resistance-angle data set corresponding to each pedal swing. Subsequently, the processor 41 can find the maximum resistance value R in the resistance-angle data set corresponding to the first swing (i.e., the first round mentioned above) of each pedal. MAX_S1 And the maximum resistance value R in the resistance-angle data set corresponding to the last swing of each pedal (i.e., the Nth round mentioned above). MAX_SNNext, the processor 41 can control the motor to rotate at a relatively fast speed so that each pedal swings a predetermined number of times. During each swing of each pedal, the processor 41 obtains the corresponding pressure value through the pressure sensor. The processor 41 can obtain the resistance-angle data set corresponding to each pedal swing. Then, the processor 41 can find the maximum resistance value R in the resistance-angle data set corresponding to the first swing (i.e., the first round mentioned above) of each pedal. MAX_F1 And the maximum resistance value R in the resistance-angle data set corresponding to the last swing of each pedal (i.e., the Nth round mentioned above). MAX_FN Finally, processor 41 can use the following relation: The degree of post-activation inhibition (PAD) was calculated.

[0054] In practical applications, multiple pressure sensors 91 can be set at the front and rear ends of a single pedal 3. The pressure measured by the pressure sensor 91 set at the rear end can be used to represent the resistance of the knee joint, while the pressure measured by the pressure sensor 91 set at the front end can be used to represent the resistance from the ankle joint. The processor 41 of the control module 4 can adjust the angle of the control pedal 3 according to the pressure values ​​of the pressure sensors 91 at the front and rear ends.

[0055] In one preferred embodiment, the processor 41 of the control module 4 may determine that the user's foot may not be correctly positioned (has already left the pedal) when the pressure values ​​returned by the multiple pressure sensors 91 of each pedal 3 are too small, i.e., less than a threshold value, such as 0.95 times the pressure value before swinging (or the pressure value at the initial angle). In this case, the control module 4 may control an alarm device to activate, thereby reminding the user and achieving the effect of preventing mistaken identity. The alarm device may include, for example, a horn, a light-emitting unit, etc. When the alarm device is activated by the control module 4, the alarm device may emit a specific sound, emit a specific light beam, etc.

[0056] In different embodiments, the processor 41 of the control module 4 may determine whether to adjust the training parameters for the next round based on the pressure values ​​returned by the multiple pressure sensors 91 in the current round. For example, if the processor 41 of the control module 4 detects that the resistance in this round is too high (i.e., the pressure value sensed by the pressure sensor 91 is relatively high), it will reduce (or stop) the motor speed and / or reduce the swing amplitude of the pedal 3 in the next round. Or, if the processor 41 of the control module 4 detects that the resistance in this round is too high or too low, it will adaptively adjust the motor speed and / or the swing amplitude of the pedal 3 in the next round.

[0057] In one embodiment, before executing the training program, the control module 4 may first detect and record the high-tension level of the user's feet. After executing the training program, the control module 4 may also record the high-tension level of the feet (i.e., calculate the aforementioned PAD). Thus, the control module 4 can determine whether the user's foot tension has recovered by comparing the high-tension level of the user's feet. For example, if a stroke patient cannot move one side (e.g., the left or right leg) normally, the control module 4 can further use the comparison of the high-tension level of the feet as one of the indicators for monitoring the user's treatment effectiveness. The high-tension level detection of the user's feet by the control module 4 refers to the control module 4 controlling the two pedals 3 to swing at a predetermined swing speed. During this process, the control module 4 will obtain the corresponding pressure values ​​in real time through multiple pressure sensors, and the control module 4 can calculate the PAD of the user's calves before training.

[0058] In another embodiment, since the calf muscles increase blood oxygen consumption during training, one of the sensing modules 9 may also include a blood oxygen detector 92, which is correspondingly installed on one of the pedals 3. The blood oxygen detector 92 is used to detect the pulse oxygen saturation (SpO2) of the user's foot (sole or toes) placed on one of the pedals 3. The control module 4 can use the detection results of the blood oxygen detector 92 as one of the indicators for monitoring the state of the user's calf muscles. For example, the processor 41 of the control module 4 can simultaneously derive the correlation between pulse oxygen saturation (SpO2) and various indicators (high tension, muscle rigidity, muscle spasm, post-activation inhibition (PAD) degree) based on pulse oxygen saturation (SpO2) and resistance-angle data sets. For example, the changes of various indicators (high tension, muscle rigidity, muscle spasm, post-activation inhibition (PAD) degree) under aerobic and anaerobic training can be obtained separately.

[0059] Please refer to the following: Figure 8 and Figure 9 The difference between this embodiment and the previous embodiment is that the drive module 2 may also include an adjustment mechanism 10, which is disposed on the base 1. The two pedals 3 are pivotally connected to the adjustment mechanism 10, and the operation interface 6 is electrically connected to the adjustment mechanism 10. The user can control the adjustment mechanism 10 by operating the operation interface 6, thereby moving the two pedals 3 away from or towards the base 1, and thus adjusting the initial angle of the two pedals 3.

[0060] When the user controls the adjustment mechanism 10 to move the two pedals 3 away from the base 1, when each pedal 3 is in the first position, the first angle θ1 formed between the plane P1 where each placement area 31 is located and the horizontal plane P is negative; while when each pedal 3 is in the second position, the second angle θ2 formed between the plane P2 where each placement area 31 is located and the horizontal plane P can be positive.

[0061] The applicant discovered that continuous, small-range passive ankle movement training can significantly reduce spasticity and simultaneously restore the inhibition following activation of the Hoffmann reflex. Furthermore, the regulation of spinal cord circuits (inhibition following activation) also shows significant recovery. Moreover, continuous activity training also results in muscle fiber recovery (fast-twitch to slow-twitch muscle contractions). Therefore, patients with spasticity symptoms can effectively reduce muscle tension and thus decrease the frequency of spasticity by using the training device 100 for reducing high tension of the present invention.

[0062] In summary, the training device for reducing high tension of the present invention is simple to operate and can be operated by the patient almost independently, and will not cause any side effects to the patient's body.

[0063] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made based on the description and drawings of the present invention are included within the protection scope of the present invention.
