Description

Technical Field

[0001] The present invention relates to the technical field of motor function rehabilitation, in particular to a Felix stick suitable for stroke patients. Background Art

[0002] Stroke patients suffer from a common cerebrovascular disease, and most patients have varying degrees of upper limb dysfunction, including shoulder pain, shoulder dislocation, proprioception loss, and decreased motor function. Proprioception is a contributing factor to upper limb movement, shoulder joint stability, and central reorganization. Its loss can cause soft tissue damage, increased pain, and decreased motor ability in stroke patients in the later stages of recovery. How to enhance the proprioception of stroke patients and improve their upper limb motor function at an early stage is a major challenge in rehabilitation. Currently, passive exercise, nerve impulse transmission training, suspension training, motor imagery therapy, etc. are mainly adopted, which require the help of others or the individual needs a strong concentration, are not interesting, and it is difficult for patients to evaluate the effect of the training.

[0003] The Fili stick is a type of vibration stimulation. As an external stimulus, it can stimulate tendons, muscles, proprioceptors, etc. When the muscles are stimulated by vibration, the intrafusal muscle sensory device is passively stretched, causing the α motor nerve endings to deform, and the afferent impulses of type Iα fibers increase, which can cause the activity of α motor neurons that control the same muscle to increase, thereby contracting the extrafusal muscles and increasing the proprioceptive input of the cerebral cortex. Through the unique connection between the S1 area and the M1 area, the excitability of the motor cortex is increased, affecting the central regulation of motor function; low-frequency vibration shortens the latency of muscle evoked potentials, activates the excitability of the brain's motor cortex, promotes brain function remodeling, and improves posture control ability; active vibration training can prompt the central nervous system to issue regulatory instructions, potential motor units are activated, giving patients positive feedback and enhancing their confidence in recovery.

[0004] However, existing Felix sticks generally have a fixed weight and are difficult to adjust according to the patient's specific conditions, such as limb strength, severity of the disease, etc., to personalize the weight adjustment. For some patients with weaker strength, the standard weight Felix stick may be too heavy, resulting in them being unable to use the equipment correctly for effective training; while for patients with better strength, it may not provide sufficient resistance to further enhance the training effect.

[0005] Furthermore, existing Felix sticks primarily rely on active movement by the patient. This limits their usefulness for patients in the early stages of stroke, those with severe limb paralysis, and those unable to actively and effectively exercise. Unlike passive training devices, they cannot directly assist with limb movement, helping to mobilize joints and strengthen muscles. However, the Felix stick can be very helpful in the recovery of these patients, quickly awakening deep muscles.

[0006] Therefore, how to help these patients quickly recover their motor ability using a flexi-bar is a technical problem that needs to be solved urgently at present. Summary of the Invention

[0033] By reading the following detailed description of the preferred embodiments, various other advantages and benefits will become clear to those of ordinary skill in the art. The drawings are only for the purpose of showing the preferred embodiments and are not considered to be a limitation of the present invention. Moreover, throughout the drawings, the same reference numerals are used to represent the same components. In the drawings:

[0035] Figure 2 A schematic diagram of the threaded connection of the counterweight in an embodiment of the present invention is shown. Detailed Embodiments

[0036] The exemplary embodiments of the present invention will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0037] An embodiment of the present invention provides a FlexiBar applicable to stroke patients, as Figure 1 shown, including:

[0038] A holding part 101, two ends of the holding part 101 symmetrically extend elastic bars 102, and counterweights 103 are arranged at the ends of the elastic bars 102;

[0039] A pressure sensor 1011, an accelerometer 1012, and a gyroscope 1013 are arranged inside the holding part 101. Among them, the accelerometer 1012 and the gyroscope 1013 are used to monitor the movement frequency, and the pressure sensor 1011 is used to monitor the holding force;

[0040] The counterweight 103 includes: a basic counterweight and an adjustable counterweight. Among them, a vibration module 1031 is arranged inside the basic counterweight for providing vibration compensation;

[0041] A processor 1014 is also arranged inside the holding part 101. The processor 1014 is used to determine a target frequency based on the holding force of the stroke patient, monitor whether the movement frequency of the patient reaches the target frequency, and if not, control the vibration module 1031 to perform vibration compensation to reach the target frequency.

[0042] First, according to the structure of the traditional FlexiBar, it includes a holding part 101, elastic bars 102, and counterweights 103. The user holds the holding part 101 with the hand, and the arm vibrates back and forth to activate the shaking of the FlexiBar.

[0043] However, for stroke patients, their motor ability is insufficient, so they cannot meet the minimum oscillation requirements.

[0044] Therefore, in the present invention, a pressure sensor 1011, an accelerometer 1012, and a gyroscope 1013 are arranged inside the holding part 101. Among them, the accelerometer 1012 and the gyroscope 1013 are used to monitor the movement frequency, and the pressure sensor 1011 is used to monitor the holding force.

[0045] Specifically, based on the data collected by the accelerometer 1012 and the gyroscope 1013, the acceleration waveform, the cycle peak value, and the cycle are determined; the processor calculates the movement frequency based on the cycle peak value and the cycle.

[0046] Among them, the gyroscope 1013 is used to monitor whether it is in a balanced state. If it is in a balanced state, the accelerometer 1012 is turned on.

[0047] Next, the accelerometer 1012 starts to calculate. Taking 30 seconds as an example, if 120 peak values are detected, then the corresponding movement frequency is 120 / 30 = 4.0 Hz. However, since the movement frequency needs to meet 4.5 - 5.0 Hz to achieve the rehabilitation training effect.

[0048] Therefore, a vibration module 1031 is arranged inside the base counterweight of the counterweight 103 for providing vibration compensation.

[0049] Among them, the vibration module 1031 includes: a brushless motor and an eccentric mass block; when the brushless motor rotates, it drives the rotation of the eccentric mass block to form vibrations with a preset frequency, and the vibration frequency is adjusted by controlling the rotation speed of the brushless motor.

[0050] In a specific implementation manner, a battery pack is also arranged inside the base counterweight for providing driving power supply for the brushless motor. By controlling the amount of electricity, the rotation speed of the brushless motor is controlled, and thus the vibration frequency is controlled.

[0051] Next, a processor 1014 is also arranged inside the holding part 101. The processor 1014 is used to determine the target frequency based on the holding force of the stroke patient, monitor whether the movement frequency of the patient reaches the target frequency, and if not, control the vibration module 1031 to perform vibration compensation to reach the target frequency.

[0052] There is a corresponding relationship table between the holding force and the target frequency. Among them, the greater the holding force, the greater the target frequency. However, the target frequency is also within the preset frequency range, and the preset frequency is 4.5 - 5.0 Hz.

[0053] If the patient's holding force is small, the target frequency is selected as 4.5 Hz. If the holding force is very large, the target frequency of 5.0 Hz can be appropriately selected.

[0054] The accelerometer 1012 and gyroscope 1013 inside the holding part are used to monitor the patient's movement frequency, and determine whether the movement frequency reaches the target frequency. If not, the vibration module is controlled to perform vibration compensation so as to reach the target frequency. For example, if the monitored movement frequency of the patient is 4.0 Hz and the target frequency is 4.5 Hz, since 4.0 Hz does not reach the target frequency of 4.5 Hz, therefore, the vibration module 1031 needs to be turned on for vibration. Since the frequency to be compensated is 0.5 Hz. Therefore, it is necessary to control the vibration frequency of the vibration module 1031 to reach 0.5 Hz. At the same time, it is also necessary to control the compensation during one oscillation of the flexi-bar so that one oscillation can reach 4.5 Hz. Only in this way can the training effect be achieved.

[0055] In an optional implementation manner, the holding part 101 further includes: a display screen for real-time displaying the movement time, movement frequency, and completion status;

[0056] An LED light ring for displaying in red when it is monitored that the patient's movement frequency exceeds the preset frequency, and displaying in green when it is monitored that the patient's movement frequency meets the preset frequency;

[0057] A buzzer alarm device for providing a buzzer alarm when the patient's movement frequency exceeds the preset frequency;

[0058] A voice feedback module for sending out corresponding voice feedback based on the movement frequency.

[0059] Among them, the movement time is timed by the internal timing module. The timing module is connected to the accelerometer 1012 and gyroscope 1013 and is used to start timing when an oscillation is monitored to start.

[0060] Displaying the movement time, movement frequency, and completion status through the display screen can always remind the patient of the movement progress.

[0061] Through the reminder function of the LED light ring and the collaborative alarm function of the buzzer alarm device, the patient's movement status is reminded. Moreover, this reminder and alarm function is mainly for the alarm in the active mode, and it can be directly seen whether the movement frequency deviates, so as to directly remind the patient.

[0062] When the patient's movement frequency does not reach the target frequency, the voice feedback module encourages the patient by sending out encouraging voices; when the patient's movement frequency reaches the target frequency, it praises the patient by sending out praising voices to give the patient motivation; when the patient's movement frequency exceeds the target frequency, it sends out reminder voices to remind the patient to pay attention. Through voice feedback in various ways, the patient can clearly understand the current movement state so as to adjust in time.

[0063] In an alternative embodiment, the adjustable counterweight can be composed of 50g×2, 80g×2, 100g×2, and 120g×2. The adjustable counterweight can be connected to the basic counterweight through a magnetic quick-release interface. For example, the basic counterweight is a groove structure, and a magnetic structure is arranged inside the groove, so that the adjustable counterweight can be sequentially embedded and adsorbed in the groove, and thus the adjustable counterweight will not be thrown out during vibration in the movement process. At the same time, the magnetic quick-release method is also convenient for disassembly and connection, improving the convenience of use.

[0064] In another way, as Figure 2 shown, the adjustable counterweight is connected to the basic counterweight through a thread. By means of threaded rotation connection, the adjustable counterweight can be tightly connected to the basic counterweight without falling off, improving safety.

[0065] In an alternative embodiment, the elastic rod 102 adopts a carbon fiber frame. Since the strength of the carbon fiber material is more than 5 times that of steel, it can withstand high-stress repeated deformation, ensuring that the elastic rod is not easily broken during severe stretching or bending. Moreover, the density of carbon fiber is only 1 / 4 of that of steel and 2 / 3 of that of aluminum, significantly reducing the overall weight of the elastic rod.

[0066] In an alternative embodiment, the following are also provided inside the holding part 101:

[0067] A heat calculation module, connected to the processor 1014, is used to determine the heat consumption of the patient based on the target frequency, exercise duration, and patient participation ratio.

[0068] Specifically, the heat consumption of the patient = 0.019 (benchmark value) × f × T × r, where f is the exercise frequency, the exercise duration is T, and the patient participation ratio is r. Among them, r is the ratio between the patient's exercise frequency and the target frequency.

[0069] By calculating the heat consumption, it is displayed through the completion status of the display screen, so that the patient can clearly understand their own exercise situation.

[0070] In an alternative embodiment, the following is also provided inside the holding part: a Bluetooth module, connected to the patient's terminal device, is used to send the exercise frequency and heat consumption to the patient's terminal device, so that the terminal device records the exercise situation.

[0071] In a specific embodiment, the patient's terminal device is provided with a relevant APP, and through Bluetooth transmission, it is recorded and saved in the APP for later viewing.
