This invention relates to a method for continuous motion prediction in patients with cerebral palsy. The method includes: acquiring sEMG data, IMU data, and ground truth joint angles of the subjects and constructing a dataset; dividing the dataset into training, validation, and test sets for each subject according to time sequence; standardizing the collected EMG and IMU data for each subject to obtain standardized sequence data; inputting the standardized sequence data of each subject into a trained prediction network, which includes parallel TCN and GAT modules. The TCN module extracts IMU temporal features, and the GAT module extracts sEMG spatial features. The two types of features are fused through a multimodal fusion module and then input into a BiLSTM network for bidirectional temporal modeling to capture the bidirectional temporal dependence of movements. Finally, a regression output module outputs the standardized predicted angles. Compared with existing technologies, this invention has advantages such as achieving continuous and accurate motion prediction for patients with cerebral palsy and enhancing cross-subject generalization ability.

This invention discloses a game-interactive fine motor training device for children with cerebral palsy, relating to the field of cerebral palsy motor training. An audio-visual interactive button is nested inside a preset base, and a first return spring is fixedly connected to the lower end of the button, with the first return spring engaging with the inner side of the preset base. A fixed top rod is fixedly connected to the inner side of the preset base, extending along the inner side of the interactive button. A guide support structure is provided on the inner side of the interactive button. This game-interactive fine motor training device for children with cerebral palsy includes a guide support structure that prompts the user whether the pressure applied is appropriate. Once the pressure is sufficient, the user can release the button, simulating fine motor operations in daily life, such as single-finger clicking or alternating pressing. The child can then determine whether their pressure application is adequate.

The method is conducive to formulating a specific rehabilitation scheme and evaluating the rehabilitation treatment effect by clinicians, and better promotes the rehabilitation treatment of children with cerebral palsy.

This utility model discloses a sitting posture training chair suitable for children with cerebral palsy, including a chair board and a base. The bottom of the chair board is formed with at least one vertically extending connecting leg, which is vertically and movably inserted into the top of the base. The top surface of the chair board has two sets of symmetrically arranged upper holes, each set of upper holes including at least three parallel upper through holes, and a thigh strap is detachably threaded between any two upper through holes in the same set. The front side of the base has two sets of symmetrically arranged lower holes, each set of lower holes including at least three parallel lower through holes, and a calf strap is detachably threaded between any two lower through holes in the same set.

The present application provides a high-efficiency, safe and clinical-grade standard neural stem cell preparation method, which realizes the fate reprogramming and directional differentiation of cells under serum-free culture conditions by screening and optimizing specific small molecule compound combinations, and induces the obtainment of neural stem cells with high proliferation capacity and multi-directional differentiation potential. The method not only significantly improves the induction efficiency and quality of neural stem cells, but also avoids the influence of serum batch difference on experimental results in traditional methods, reduces production cost, and provides reliable technical support for clinical application. By transplanting the neural stem cells into the damaged area of cerebral palsy patients, the reconstruction of neural circuit and functional recovery can be promoted, and the motor ability and life quality of the patients can be improved. The serum-free clinical-grade neural stem cell preparation method and its application in cerebral palsy rehabilitation provided by the present application have the characteristics of high efficiency, stability and clinical applicability, and provide a new solution for central nervous system injury repair.
