Surgical systems and methods involve a robotic manipulator with a force sensor and a surgical tool that holds a screw. The screw has a known thread geometry. A navigation system tracks a pose of a target anatomy. Controller(s) store the known thread geometry and control the robotic manipulator to maintain the rotational axis on a planned trajectory with respect to the target anatomy based on the tracked pose of the target anatomy. The controller(s) detect, with the force sensor, a force applied by a user. The controller(s) control a rotational rate of the surgical tool to rotate the screw about a rotational axis and an advancement rate of the surgical tool to linearly advance the screw along the planned trajectory. The rotational rate and the advancement rate are based on the force applied by the user and are proportional to the known thread geometry.

This application provides a method and system for gait and cognitive training adjustment for patients with cerebral small vessel disease. The method superimposes a preset cognitive task during the patient's normal walking process, simultaneously collecting gait and cognitive data under dual-task conditions to obtain dual-task data. Based on gait baseline data, cognitive baseline data, and dual-task data, a dual-task interference index is calculated. Postural control training is then performed on the patient using a balance training device. The perturbation parameters and visual feedback parameters of the balance training device are adaptively adjusted according to the dual-task interference index grading results. Within the training cycle, the dual-task walking phase is repeatedly executed at a preset retest frequency, updating the dual-task interference index and its corresponding grading results. Based on the updated grading results, the balance device training parameters for the next training cycle are dynamically adjusted. This method can suppress the influence of learning effects on training results during the dual-task training phase, improving the accuracy of the training control process for patients with cerebral small vessel disease.

The invention provides a posture control method of a conveyed object and a conveying system using the posture control method, which can improve the reliability of posture control of the conveyed object compared with the prior art. The present invention relates to a method for controlling the posture of a conveyed object, which is a method for controlling the conveyance posture of the conveyed object by blowing an air flow toward the conveyed object on a conveyance path while conveying the conveyed object in a conveyance direction along the conveyance path, in which the conveyed object is floated by a first air flow on the conveyance path and the conveyed object is floated by a second air flow on the conveyance path. The floating conveying object is rotated by a second air flow on the conveying path, thereby changing the posture of the conveying object.

The utility model relates to the technical field of training devices, in particular to a head and neck posture control training device which comprises a mounting seat, a counterweight plate is inserted into the inner surface of the mounting seat, a top plate is arranged on the inner surface of the mounting seat, a base is arranged on the lower surface of the mounting seat, and an arc-shaped groove is formed in the lower surface of the base. By arranging the mounting seat, the top plate, the counterweight plate and the like, a user can insert the top plate into the mounting seat to fix the counterweight plate, and the mounting seat is connected with the base through the spring, so that the spring and the mounting seat can give a feedback to the user when the head of the user abuts against the base, and the user can feel more comfortable when the head of the user abuts against the base. The spring can increase the instability of the mounting base, once the head or the cervical vertebra deviates, the mounting base inclines and swings, a user can quickly recognize whether the head and the neck are in a neutral position or not through the top plate in front of the mirror, and the user is helped to adjust the posture to maintain the neutral position of the head and the cervical vertebra.

A determination device (100) includes a shaking detector (10) that detects shaking when a person moves and a controller (20). A frequency spectrum analysis is performed by decomposing shaking data output from the shaking detector (10) into frequency components. In a frequency spectrum obtained by the frequency spectrum analysis, a first peak value, a second peak value, and a third peak value appear in order from low to high frequencies. The controller (20) determines a state of the person's body based on the first peak value, the second peak value, and the third peak value.
