Description

Technical Field

[0001] This invention relates to the field of upper limb training technology. More specifically, this invention relates to training methods and systems based on upper limb press devices. Background Technology

[0002] An upper limb press machine is a device used for rehabilitation and fitness, primarily for exercising and strengthening the muscles and strength of the upper limbs (including the arms, shoulders, and chest). It typically consists of a bicycle-like machine, but without pedals; instead, it has a handlebar system that the user pushes with their hands. Upper limb press machines offer a variety of movement modes, including forward and reverse pushing, as well as different resistance levels and training programs to meet the needs and rehabilitation goals of different users.

[0003] However, when patients use the upper limb press machine, the resistance of the machine is pre-set, while the pushing force applied by the patient to the push bar during training varies. This can lead to difficulty pushing the push bar or easy pushing of the push bar, thus failing to achieve a good training effect on the patient's upper limbs. Summary of the Invention

[0004] This invention provides a training method and system based on an upper limb pusher, aiming to solve the problem in related technologies where the pushing force applied by the patient to the push bar during training varies, resulting in either difficulty or ease in pushing the push bar, thus failing to achieve a good training effect.

[0005] In a first aspect, the present invention provides a training method based on an upper limb pusher, comprising: the upper limb pusher having a push-pull bar for training a patient's upper limb, characterized in that it includes: collecting the maximum value of the pushing force applied by the patient to the push-pull bar; setting a force of the same magnitude as the maximum value as the maximum resistance value of the push-pull bar; adjusting the maximum resistance value according to the difference between the pushing force and the maximum resistance value when the patient pushes the push-pull bar; until the patient can smoothly push and pull the push-pull bar, wherein smooth pushing and pulling means that the movement speed of the push-pull bar is within a preset range; calculating a target resistance value based on the patient's training time and the maximum resistance value during the training process; recording the training of pushing the push-pull bar as effective training in response to the patient's pushing force being greater than the target resistance value; and terminating the upper limb rehabilitation of the patient and the training in response to the patient's effective training number meeting a preset threshold.

[0006] In one embodiment, collecting the maximum value of the pushing force applied by the patient to the push-pull rod includes: in response to the patient needing to continue training if the number of effective training sessions during training is less than a preset threshold.

[0007] In one embodiment, collecting the maximum value of the pushing force applied by the patient to the push-pull rod includes: adjusting the angle of the upper limb pusher to a target angle; monitoring the pushing force of the patient pushing the push-pull rod within a preset time period; and obtaining the maximum value of the pushing force applied by the patient within the preset time period.

[0008] In one embodiment, acquiring the maximum value of the pushing force applied by the patient to the push-pull rod includes: adjusting the angle of the upper limb pusher to a target angle; the patient pushing the push-pull rod to move; and in response to pushing the push-pull rod to the maximum position, acquiring the maximum value of the pushing force applied by the patient to the push-pull rod during the pushing process.

[0009] In one embodiment, adjusting the resistance based on the difference between the pushing force and the resistance when the patient pushes the push-pull rod includes: reducing the maximum resistance value when the absolute value of the difference between the pushing force and the maximum resistance value is greater than a preset threshold and the pushing force is less than the maximum resistance value; and increasing the maximum resistance value when the absolute value of the difference between the pushing force and the maximum resistance value is greater than a preset threshold and the pushing force is greater than the maximum resistance value.

[0010] In one embodiment, the drag is adjusted only if the difference between the thrust and the drag meets a preset threshold.

[0014] The above and other objects, features, and advantages of exemplary embodiments of the present invention will become readily apparent upon reading the following detailed description with reference to the accompanying drawings. In the drawings, several embodiments of the invention are illustrated by way of example and not limitation, and like or corresponding reference numerals denote like or corresponding parts, wherein:

[0015] Figure 1 This is a schematic diagram illustrating an upper limb training process according to an embodiment of the present invention; Figure 2This is a schematic diagram illustrating a system according to an embodiment of the present invention. Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0018] In one embodiment, the upper limb pusher includes a push-pull bar and a pressure sensor. The patient trains the upper limb by pushing the push-pull bar, and the pressure sensor can be used to monitor the force exerted by the patient on the push-pull bar.

[0019] Step S101: Collect the maximum value of the pushing force applied by the patient to the push-pull rod, and set the push-pull rod with a force of the same magnitude as the maximum value as the maximum resistance value of the push-pull rod.

[0020] In one embodiment, when collecting the maximum force exerted by the patient on the push-pull rod, a suitable tilt angle of the upper limb pusher needs to be selected as the target angle, such as 5°, 10°, or 15°. Then, the angle of the upper limb pusher is adjusted to the target angle. Next, the force exerted by the patient pushing the push-pull rod is monitored within a preset time period. The maximum force exerted by the patient within the preset time period is selected, and finally, a force equal to the maximum force is set as the maximum resistance value of the push-pull rod.

[0021] For example, the tilt angle of the upper limb pusher is adjusted to 10°, the preset time period is 20 seconds, and the pushing force of the patient pushing the push bar is monitored within 20 seconds. The changes in the patient's pushing force within 20 seconds are monitored to be 60N, 59N, 98N and 73N. Then, 98N is selected as the maximum value of the pushing force applied by the patient to the push bar, and 98N is applied as resistance to the push bar. At this time, the resistance of 98N is the maximum resistance value that the patient can withstand.

[0022] In another embodiment, acquiring the maximum value of the pushing force applied by the patient to the push-pull rod further includes adjusting the angle of the upper limb pusher to a target angle. The patient then pushes the push-pull rod to move. When the patient pushes the push-pull rod from the initial position to the maximum position (i.e., the furthest distance), the maximum value of the pushing force applied by the patient during the process of pushing the push-pull rod from the initial position to the maximum position is acquired. Finally, a force equal to the maximum value is set as the maximum resistance value of the push-pull rod.

[0023] Step S102: Adjust the maximum resistance value based on the difference between the pushing force and the maximum resistance value when the patient pushes the push-pull lever; until the patient can push and pull the push-pull lever smoothly, where smooth pushing and pulling means that the movement speed of the push-pull lever is within a preset range; In one embodiment, the pushing force of the patient pushing the lever is monitored in real time, the difference between the patient's pushing force and the maximum resistance value is calculated, and it is determined whether the difference between the patient's pushing force and the maximum resistance value is greater than a first threshold. If the difference between the patient's pushing force and the maximum resistance value is greater than the first threshold, the maximum resistance value is adjusted until the patient can push and pull the lever smoothly. Smooth pushing and pulling means that the movement speed of the lever is within a preset range.

[0024] Regarding adjusting the maximum resistance value, the following measures are implemented: when the absolute value of the difference between the pushing force and the maximum resistance value is greater than a preset threshold, and the pushing force is less than the maximum resistance value, the maximum resistance value is reduced; when the absolute value of the difference between the pushing force and the maximum resistance value is greater than a preset threshold, and the pushing force is greater than the maximum resistance value, the maximum resistance value is increased until the patient can push and pull the lever at a preset speed.

[0025] For example, if the monitored pushing force from the patient is N1, the maximum resistance of the push-pull rod is N2. When ,and When Q is the preset threshold, the maximum resistance needs to be increased. The increased maximum resistance value is N2+Z, where Z is the set value for each increase or decrease in resistance. This continues until the patient can push and pull the lever at a preset speed, where the preset speed refers to the speed at which the patient pushes and pulls the lever without fluctuating above or below the second threshold.

[0026] like ,and At this point, the maximum resistance value needs to be reduced to N2-Z until the patient can push and pull the lever at the preset speed.

[0027] Step S103: Calculate the target resistance value based on the patient's training time and maximum resistance value during the training process.

[0028] In one embodiment, during upper limb training, if a patient can push the lever while it still exhibits maximum resistance, it indicates that the patient has reached the standard for normal upper limb function during this training session. The more times the patient achieves this standard, the closer their upper limb is to recovery. It's important to note that prolonged pushing and pulling of the lever can lead to upper limb fatigue, inevitably reducing pushing force. Using the previous maximum resistance value as the standard would indirectly raise the completion threshold. Therefore, a target resistance value needs to be set based on the patient's training time. The longer the training time, the lower the target resistance value should be.

[0029] The formula for calculating the target resistance value is as follows: Y = Q - (aQ) -T ); where Y represents the target resistance value, Q represents the maximum resistance value, T represents the patient's training time, and a represents a constant.

[0030] The above are methods for training the patient's upper limbs. Below are the target conditions for whether the patient has completed rehabilitation. When the patient meets the target conditions, it indicates that the patient's upper limbs have fully recovered and no further training is needed. Details are as follows: Step S104: In response to the patient's pushing force being greater than the target resistance value, the training of pushing and pulling the lever is recorded as valid training.

[0031] In one embodiment, if the pushing force applied by the patient to the push-pull bar is greater than the target resistance value, it indicates that the patient's upper limb has achieved the normal pushing force during the push-pull process, and this training session is recorded as valid. Conversely, if the pushing force applied by the patient is less than the target resistance value, it indicates that the patient has not achieved the normal pushing force during the training and further training is required.

[0032] Step S105: In response to the patient's effective training number meeting the preset threshold during the training process, the patient's upper limb rehabilitation is completed and the training ends.

[0033] In one embodiment, if the patient's effective training repetitions reach a preset threshold during training, it indicates that the patient's upper limb has recovered to normal and no further training is needed. If the patient's effective training repetitions are less than the preset threshold, it indicates that the patient's upper limb has not yet recovered to normal and further training is required.

[0034] For example, each training session using the upper limb pusher is 10 minutes. Then, the number of times the patient pushes the bar in accordance with effective training within 10 minutes is counted. If the number of times the patient pushes the bar in accordance with effective training reaches a preset threshold, it indicates that the patient's upper limb has returned to normal.

[0035] In one embodiment, the number of times each pushing and pulling the lever constitutes effective training can also be counted. If the sum of these two effective training counts meets a preset threshold, it can also be indicated that the patient's upper limb has recovered to normal.

[0036] By following the steps above, the resistance of the push-pull lever can be adjusted according to the patient's real-time pushing force, thus enabling adaptive training based on the patient's level of obstacle and improving training efficiency. Furthermore, by adjusting the maximum resistance value in real-time based on the patient's training time, the statistical results of training are more accurate, allowing for precise patient assessment and training.

[0037] This invention also provides a training system based on an upper limb lifting device. For example... Figure 2 As shown, the system includes a processor and a memory. The memory stores computer program instructions, which, when executed by the processor, implement a training method based on an upper limb pusher according to the first aspect of the present invention.
