Description

A trunk posture correction mechanism for children with cerebral palsy

technical field

The invention relates to the technical field of posture correction mechanical equipment, in particular to a trunk posture correction mechanism for children with cerebral palsy.

Background technique

An upright physiological posture is a prerequisite for children to learn correct movement patterns. The correct posture of the trunk is to provide the possibility for children with lower limb impairment to experience independent standing, including standing still and walking. Proper posture of the trunk ensures proper alignment of the body, allows extension of the lower extremity flexors, improves head control and trunk stability. At present, most lower extremity exoskeleton systems lack research on trunk posture and stability. They only focus on assisting lower limb walking while ignoring the function of the trunk. Ignoring the correct adjustment of trunk posture may reduce the effectiveness of exoskeleton assistance.

For children with lower extremity dysfunction, correct trunk posture helps children to transfer body weight correctly on their feet, making it easier for them to stride and walk. In addition, trunk support devices need to be tailored to each user based on height, weight, muscle strength, and movement patterns, allowing them to maintain a correct upright posture.

Therefore, the potential demand for upper limb trunk support equipment applicable to intelligent lower limb exoskeleton rehabilitation robots is relatively large.
