To effectively achieve rehabilitation goals, specific training plans are required for individuals of different ages, etiologies, and physical characteristics. Acquiring relevant physical data during rehabilitation training is essential for perceptual interaction and confidence building, as well as for executing training plans and evaluating training outcomes and functional recovery.
[0003] Existing rehabilitation training equipment designs often focus on guiding reciprocating motion to achieve a single action.

DETAILED DESCRIPTION
[0052] In order to facilitate understanding of the technical solution of the present invention, the following is a detailed description with reference to the accompanying drawings and specific embodiments.
[0053] Example 1
[0054] like Figure 1-3 As shown, a method for analyzing hand limb rehabilitation training data is shown, wherein the horizontal axis of each curve represents time, and the vertical axis represents the superposition of torque and rotation angle; for example, in the training and recovery of the wrist joint, the torque is adjusted to 50N·m, and the rotation limit of the wrist trainer 2 is 90°, then at time 0, the vertical axis value is 50, and as the rotating rod 233 rotates, the curve begins to rise, rising to the vertical axis value of 140, and then the rotating rod 233 is rotated in the opposite direction, the curve begins to fall, and drops to the vertical axis value of 50, wherein the difference in the vertical axis values is the rotation angle, 50N·m is a specific position torque value, and the rotation speed can be obtained by the ratio of the rotation angle to the rotation time.
[0055] The specific steps include:
[0056] Step 1: Construct a rehabilitation assessment standard curve. Use the rotation angle, specific position torque, and rotation speed of the wrist, arm, and shoulder joints that can be achieved by a healthy person (under medical standards) operating the training equipment to construct the first rehabilitation grading assessment standard curve. This curve is the minimum standard that ordinary people can use in their daily lives. The horizontal axis of the curve represents time, and the vertical axis represents the superposition of torque and rotation angle.
[0057] Step 2: Collect the rotation angle, specific position torque, and rotation speed of the wrist, arm, and shoulder joints that can be achieved by operating the training equipment in the patient's current health state, and establish a second rehabilitation grading assessment standard curve that meets the trainee's needs. The curve is a rehabilitation standard specially customized for the trainee, and the value of the curve is lower than the first rehabilitation grading assessment standard curve. The horizontal axis of the curve represents time, and the vertical axis represents the superposition of torque and rotation angle.
[0058] Step 3: Calculate the weighted average of the vertical axis values on the same horizontal axis on the first rehabilitation graded assessment standard curve and the second rehabilitation graded assessment standard curve for the wrist, arm, and shoulder joints to obtain the target training curve for the joint. The horizontal axis of the curve represents time, and the vertical axis represents the superposition of torque and rotation angle.
[0059] When constructing the target training curve, the weight of the vertical axis value in the second rehabilitation graded assessment standard curve is greater than the weight of the vertical axis value in the first rehabilitation graded assessment standard curve, so that the target training curve can be closer to the current physical condition of the trainee and avoid excessive training volume for the patient. In practice, the weight range of the first rehabilitation graded assessment standard curve can be 20%-40%, and the weight range of the second rehabilitation graded assessment standard curve can be 60%-80%;
[0060] For example, on the same horizontal axis, the vertical axis value of the first rehabilitation grading evaluation standard curve is 150 (weighted 30%), and the vertical axis value of the second rehabilitation grading evaluation standard curve is 100 (weighted 70%). Then it can be concluded that the vertical axis value of the target training curve at this moment is 115, and so on, to obtain the entire target training curve.
[0061] Step 4: The patient performs rehabilitation training of the wrist, arm and shoulder joint on the hand limb rehabilitation training equipment, and compares the actual training curve generated by the actual training (the horizontal axis of the curve represents time, and the vertical axis represents the superposition of torque and rotation angle) with the target training curve, and calculates the overlap between the two. When the overlap is greater than the set value, it is determined that the training goal is achieved; wherein, the overlap is the difference or sum of the similarity and the difference improvement value, wherein the similarity can be calculated using a point-based method: EDR, LCSS, DTW or a shape-based method: Frechet, Hausdorff. Since the similarity is a percentage, the difference between the actual training curve and the target training curve is divided by 100 (or a value of 1%) to obtain a difference improvement value close to the similarity, and then the similarity and the difference improvement value are subtracted or summed to obtain the overlap.
[0062] When the vertical axis value of the actual training curve is lower than the vertical axis value of the target training curve, the difference between the actual training curve and the target training curve means that the training target has not been reached, which is a data that reduces the overlap. Therefore, the similarity and the difference improvement value are subtracted to obtain the overlap. When the vertical axis value of the actual training curve is higher than the vertical axis value of the target training curve, the difference between the actual training curve and the target training curve means that the training target has been exceeded, which is a data that improves the overlap. Therefore, the similarity and the difference improvement value are summed to obtain the overlap.
[0063] In this embodiment, when the overlap is greater than 80%, it is determined that the training goal is achieved.
[0064] Step 5: The actual training curve when the training goal is determined to be achieved is used as the new second rehabilitation graded assessment standard curve, and a weighted average calculation is performed on the vertical axis value of the same horizontal axis on the first rehabilitation graded assessment standard curve to obtain a new target training curve for a certain joint. Repeat step 4 until the degree of overlap between the actual training curve and the first rehabilitation graded assessment standard curve is greater than the set value, and it is determined to be restored to health and sent to the attending physician. In this embodiment, the set value is 80%.
[0065] like Figure 4-27 As shown, a hand limb rehabilitation training device includes a mounting frame 1 and a wrist trainer 2, a forearm trainer 3, a shoulder joint trainer 4, a single-chip microcomputer system 5, a trainer display 6 and a computer system 7 mounted on the mounting frame 1, and each of the wrist trainer 2, the forearm trainer 3 and the shoulder joint trainer 4 is provided with one or more torque sensors and one angle sensor. Figure 1 The parameter collection process is illustrated by taking wrist trainer 2 as an example.
[0066] Among them, the mechanical balance relationship model of the three training devices can be expressed as:
[0067]
[0068] Among them, T is the operating input torque, Tz is the resistance torque set by the device, and n is the rotation speed of the shaft on the device. They can all be considered as two-dimensional quantities of angle α and time t. The input torque characteristic and resistance torque characteristic can theoretically be obtained through detection. Figure 1 When the wrist exerciser 2 is operating within its full range, the torque sensor can collect the input torque signal T(t), and the angle sensor can collect the shaft angle signal α(t). When these two signals are collected synchronously on the wrist exerciser 2, they can also be converted into a two-dimensional input torque value T(α, t). The resistance torque on the wrist exerciser 2 is provided by the first damping device 23. After the first damping device 23 is preset, its damping characteristics are also determined.
[0069] The rotating rod 233 of the wrist exerciser 2 can be twisted from an angle of 0° around the axis within an angle range of ±α. The torsional resistance is determined by the elastic coefficient of the leaf spring 235 and the adjustment of the first damping adjustment device 24. Torque sensors are installed on both the left and right sides of the rotating rod 233 to collect rotational torque data. An angle sensor is also installed on the rotating rod 233 to simultaneously collect the torsion angle of the rotating rod 233. Both sets of data are transmitted in real time to the single-chip microcomputer system 5 and further to the computer system 7.
[0070] The wrist trainer 2 includes a first fixing device 21 fixedly connected to the mounting frame 1, a movable first lifting platform 22 is provided on the first fixing device 21, a first damping device 23 is installed on the first lifting platform 22, a first damping adjustment device 24 is provided on the rear side of the first lifting platform 22, the first damping device 23 includes a first shell 231, the first shell 231 is provided with a first mounting hole 232, a rotating rod 233 is passed through the first mounting hole 232, and the middle part of the rotating rod 233 is a cam 2331 A damping plate 234 is also installed in the first shell 231, and a number of leaf springs 235 are provided on the damping plate 234. Sliding grooves 236 are provided on both sides of the first shell 231, and a matching sliding member 2341 is provided on the damping plate 234. The sliding member 2341 can be embedded in the sliding groove 236 and move in the sliding groove 236. The first damping adjustment device 24 is a bolt, and a first threaded hole 221 is provided on the first lifting platform 22. The bolt passes through the first threaded hole 221 of the first lifting platform 22 and rests on the damping plate 234.
[0071] When using the wrist trainer 2, it is only necessary to rotate the rotating rod 233, and the cam 2331 will contact and squeeze the leaf spring 235, thereby generating damping to achieve the purpose of training the wrist; if the damping size needs to be adjusted, it is only necessary to rotate the bolt, for example, rotating the bolt inward will move the damping plate 234 toward the rotating rod 233, and the distance between the cam and the damping plate 234 will be reduced. It takes more force to rotate the cam, and the damping size is increased.
[0072] The rotating member 333 of the forearm exerciser 3 can be twisted within a range of ±α° about its axis starting from an initial angular position (0°). The torsional resistance is determined by the elastic coefficient of the adjustment spring 343 and the adjustment of the second damping adjustment device 34. A torque sensor is mounted on the rotating member 333 to collect rotational torque data. An angle sensor is also mounted on the rotating member 333 to simultaneously collect the torsional angle of the rotating member 333. Both sets of data are transmitted in real time to the single-chip microcomputer system 5 and further to the computer system 7.
[0073] The forearm trainer 3 includes a second fixing device 31 fixedly connected to the mounting frame 1, a movable second lifting platform 32 is provided on the second fixing device 31, a second damping device 33 is installed on the second lifting platform 32, and a second damping adjustment device 34 is provided on the second lifting platform 32, the second damping device 33 includes a second shell 331, the second shell 331 is provided with a second mounting hole 332, a rotating member 333 is rotatably installed in the second mounting hole 332, the rotating member 333 includes a rotating handle 3331 arranged on the outside, a rotating column 3332 arranged on the inside and a baffle 3333 arranged on the rotating column 3332, the second damping adjustment device 34 includes an adjusting bolt 341, an adjusting nut 342 matched with the adjusting bolt 341 and an adjusting spring 343 fixedly connected to the adjusting nut 342, and the other end of the adjusting spring 343 is connected to the baffle 3333.
[0074] When using the forearm trainer 3, one only needs to rotate the rotating handle 3331, and the baffle 3333 set on the rotating column 3332 will rotate together with the rotating handle 3331, thereby pulling the adjustment spring 343 and deforming it to generate damping. After releasing the rotating handle 3331, the adjustment spring 343 automatically resets; if the damping size needs to be adjusted, one only needs to rotate the adjusting bolt 341. Since one end of the adjusting spring 343 is fixedly connected to the baffle 3333 and the other end is fixedly connected to the adjusting nut 342, when the adjusting bolt 341 is rotated, the adjusting nut 342 will move on the adjusting bolt 341, thereby changing the length of the adjusting spring 343 to change the damping size.
[0075] The rotating ring 434 of the shoulder joint trainer 4 can be twisted within a range of ±α° around the axis starting from an initial angular position (0°). The torsional resistance depends on the elastic coefficient of the third damping device 43 and the adjustment of the third damping adjustment device 44. A torque sensor is mounted on the rotating ring 434 to collect rotational torque data; an angle sensor is also mounted on the rotating ring 434 to simultaneously collect the torsional angle of the rotating ring 434. Both sets of data are transmitted in real time to the single-chip microcomputer system 5 and further to the computer system 7. Alternatively, a strain gauge sensor on the rotating ring 434 can also be used to collect torsional data.
[0076] The shoulder joint trainer 4 includes a third fixing device 41 fixedly connected to the mounting frame 1, a movable third lifting platform 42 is provided on the third fixing device 41, a third damping device 43 is installed on the third lifting platform 42, a third damping device 43 is provided on the third damping device 43, and a third damping adjustment device 44 is provided on the third damping device 43. The third damping device 43 includes a third shell 431, the third shell 431 is provided with a third mounting hole 432, a rotating block 433 is rotatably installed in the third mounting hole 432, and the rotating block 433 is connected to the third shell 431. The rotating ring 434 is connected to the rotating ring 434, and a connecting portion 4341 is provided on the connecting portion 4341. A mounting groove 4342 is provided on the mounting groove 4342. A hand piece 435 can be installed in the mounting groove 4342. A plurality of pairs of limiting grooves 4343 are also provided in the mounting groove 4342. A limiting connecting rod 4351 is provided at the bottom of the hand piece 435. A limiting hole 4352 and a limiting sliding groove 4356 are also provided on the mounting shell 4355 of the hand piece 435. An elastic member 43 is provided at the corresponding position on the limiting connecting rod 4351. 53 and a sliding pin 4357, the sliding pin 4357 slides in the limiting sliding groove 4356. When the sliding pin 4357 slides to the top, the elastic member 4353 is compressed and deformed and retracted into the mounting shell 4355 and moves upward. When the sliding pin 4357 slides to the bottom, the elastic member 4353 is embedded in the limiting groove 4352 for limiting, preventing the limiting link 4351 from being separated from the limiting groove 4343. A herringbone groove 4354 is provided in the handpiece 435. The limiting link 4351 includes a first link The lower end of the first connecting rod is provided with two hinged ends, each of which is hinged to a second connecting rod. The second connecting rod is hinged to the third connecting rod. When the elastic telescopic member 4353 is embedded in the limiting hole 4352 located below, the second connecting rod and the third connecting rod are in a horizontal state, and the third connecting rod is embedded in the limiting groove 4343. This is the first state. When the elastic telescopic member 4353 is embedded in the limiting hole 4352 located above, the second connecting rod is in an inclined state, and the handpiece 435 can move in the mounting groove 4342. This is the second state.
[0077] When the shoulder joint trainer 4 is in use, rehabilitation training of the shoulder joint can be achieved by rotating the rotating ring 434; if the trainee has an inconvenience in holding the handpiece 435 because his arm is too long or too short, the distance between the handpiece 435 and the rotating axis can be adjusted, that is, the elastic telescopic part 4353 is pressed to lift the handpiece 435, and the elastic telescopic part 4353 is embedded in the limiting hole 4352 located above. At this time, the first connecting rod is vertical, the second connecting rod is inclined, and the third connecting rod is horizontal and does not extend into the limiting groove 4343. It can be moved in the installation groove 4342. After moving to the appropriate position, the elastic telescopic part 4353 is pressed down and the handpiece 435 is pressed downward, so that the elastic telescopic part 4353 is embedded in the limiting hole 4352 located below, thereby adjusting the distance between the handpiece 435 and the rotating axis. At this time, the first connecting rod is vertical, the second connecting rod is horizontal, and the third connecting rod is horizontal and extends into the limiting groove 4343.
[0078] The above are only preferred embodiments of the present invention. The scope of protection of the present invention shall be based on the scope defined by the claims. Several improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as the scope of protection of the present invention.
