Embodiment Construction

[0018] The technical solution of the present invention will be described in detail and completely through the accompanying drawings and embodiments below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. The gait balance training schemes completed based on equivalent software and hardware all apply to the protection category of the present invention.

[0019] The present invention is based on related hardware such as a 6-DOF motion platform and an IMU inertial sensing acquisition node, and combines an IMU attitude acquisition system with a robot motion control system through a balance training system to realize complete gait balance training.

[0020] In the active training program 11, the human body initiates the movement, and the inertial sensor collects the node 6 to collect information such as acceleration, speed, magnetic field, etc. After the nine-axis data collection algorithm 7 and the data analysis s...

Abstract

The invention discloses a gait balance training system based on a six-degree-of-freedom parallel platform. The system comprises six-degree-of-freedom platform mechanical hardware, inertial sensing acquisition nodes, an IMU sensor attitude acquisition system, a robot motion control system and a balance training system. The six-degree-of-freedom platform can provide various angle and displacement changes, apply external stimulation, provide acceleration, speed and angular speed stimulation in combination with related algorithms such as trajectory planning and somatosensory simulation of a robotmotion control system, and train the human body balance perception ability from sensory input. The inertia sensing acquisition nodes are combined with an IMU sensor attitude acquisition system to divide human body gait phases and extract human body key gait data such as stride frequency, stride speed and step length. The extracted human gait data can be used for balance ability evaluation and judgment before training and can also be used for guiding the motion form of the robot in the training process. Two training modes of a balance training system are combined, and active training and passive training of the human body are achieved. According to the invention, a multi-degree-of-freedom platform, motion data acquisition and analysis and related algorithms are introduced to realize a complete gait balance training robot, and the human body balance ability and gait characteristics can be evaluated and judged from feeling input. The blank of domestic related research is filled up, and anew gait balance training mode is added.

Description

technical field [0001] The invention aims at the field of medical rehabilitation, and aims at a gait balance training system based on a 6-degree-of-freedom motion platform for patients with balance disorders who have exercise ability. Background technique [0002] With the increase of age and the occurrence of common geriatric diseases, the balance ability of elderly patients declines rapidly, and gait abnormalities occur frequently. The balance rehabilitation and gait abnormal diagnosis at the present stage are more based on the guidance of physicians' experience, using the training movements customized by physicians, and evaluating the training effect based on subjective judgment. The balance training process is randomized, the gait evaluation standard is not unique, and a large number of experienced rehabilitation physicians are required. [0003] At present, most of the mainstream gait rehabilitation training robots in the market are exoskeleton structures, which focus ...
