This invention discloses a rehabilitation assessment method based on an autoencoder and a Softmax classifier, belonging to the field of flexible strain sensor measurement technology. Specifically, it involves: multiple trainees with known rehabilitation levels completing a Carroll hand function assessment task; finger motion monitoring gloves acquiring finger data; and processing the data through interpolation and sampling; constructing a rehabilitation level assessment model composed of an autoencoder and a Softmax classifier; training the rehabilitation level assessment model using the processed data as input and the known rehabilitation levels as training targets; having the test subject complete the task and obtain finger data to be assessed, which is then interpolated and sampled before being input into the trained rehabilitation level assessment model, outputting the rehabilitation level assessment result. This invention employs cubic Hermitian interpolation and sampling followed by equal-value interpolation, using fewer data points to more accurately reflect the characteristics of the finger data, and combining an autoencoder and a Softmax classifier to achieve high-accuracy assessment.

The manipulator comprises a machine vision module, a # imgabs 0 # method module, a one-finger meditation thumb module, a wrist joint, a palm side rolling module and a four-finger module, the # imgabs 1 # method module is installed on the wrist joint, the machine vision module, the one-finger meditation thumb module, the palm side rolling module and the four-finger module are installed on the # imgabs 2 # method module, and the machine vision module, the one-finger meditation thumb module, the palm side rolling module and the four-finger module are installed on the # imgabs 2 # method module. And the manipulator is used for realizing different massage manipulations. A # imgabs3 # method module, a one-finger meditation thumb module, a palm side rolling module and a four-finger module are arranged, and through the refined hand function module, the massage manipulation is deeply reproduced in a mode more conforming to the traditional Chinese medicine massage theory. For example, the palm center is used for reproducing a trapezoidal protrusion of the contact face between the axis of the metacarpophalangeal joint combination of the middle finger, the ring finger and the little finger and the axis of the ulnar side in the # imgabs4 # method, and the thumb movable knuckle is used for reproducing the metacarpophalangeal joint combination of the first finger through the arm with the wrist and the wrist with the fingers.

The utility model discloses a single-finger flexion and extension rehabilitation training device which comprises a far-joint fingerstall, a middle-joint fingerstall and a near-joint fingerstall, the far-joint fingerstall, the middle-joint fingerstall and the near-joint fingerstall are connected in a pivoted mode in pairs, and the far-joint fingerstall and the middle-joint fingerstall are jointly in mechanical linkage with a linear motion structure restrained by elasticity. The flexion and extension force of the distal finger stall and the middle finger stall under the driving of the finger is resisted through the elastic reset force, so that the flexion and extension training of the finger is realized. The finger rehabilitation device has the advantages that the finger rehabilitation device is particularly suitable for hand function rehabilitation treatment after cerebral apoplexy or trauma on the basis of the human body finger structure and the movement bionics principle, finger muscle strength of a patient can be recovered, the flexibility of finger joints is improved, the movement range of the finger joints is widened, and joint stiffness and muscle atrophy caused by cerebral apoplexy or trauma are relieved.

A fingertip air bag is connected in the fingertip fixing piece, and a knuckle air bag is connected in the knuckle fixing piece; two bases are connected to the supporting block, one end of the rope is connected to the rope driving module, the other end of the rope is connected to the bases, and the rope driving module drives the rope to pull the finger stretching and bending piece to achieve stretching and bending of fingers; the electrode plate is electrically connected to the low-frequency pulse module. Compared with the prior art, through the air bag-finger integrated adaptive structure, the annular wrist strap integrated modular design and the rope drive-low frequency pulse cooperative control mechanism, rehabilitation training of the hemiplegic fingers which is high in adaptability, convenient to wear, good in rehabilitation effect and easy to operate is achieved.

The utility model discloses a massager with a hand stretching and bending function, which comprises a shell, one end of the shell is provided with a hole for a palm to insert, a palm inner shell is fixedly arranged in the shell, a finger inner shell is rotatably mounted in the shell, and the palm inner shell is connected with the finger inner shell through a spring. A first air bag is arranged on the upper portion of the butt joint of the finger inner shell and the palm inner shell, convex shafts are integrally and symmetrically connected to the two sides of the finger inner shell, pin rods are further integrally connected to the two sides of the finger inner shell, an upper limiting plate and a lower limiting plate are arranged in the shell, and the convex shafts and the pin rods are slidably connected between the upper limiting plate and the lower limiting plate. The corner, away from the palm inner shell, of the lower limiting plate is an arc-shaped corner, and the protruding shaft is attached to the arc-shaped corner in a sliding mode. Automatic back-and-forth rotation of the finger inner shell is achieved through cooperation of the first air bag and the spring, natural hand bending and stretching actions are simulated, the palm inner shell and the finger inner shell are designed in a split mode and are more attached to the hand structure, and massage comfort and pertinence are improved.
