A Novel Origami Exoskeleton for Lumbar Degenerative Disc Disease on Human Spine

CSEF · 2026 Applied Mechanics (Senior Division)

Yunhao Wu

Overview

Purpose: The research aimed to solve the problem of increasing risk of degenerative disc disease (DDD) because of aging, dehydration of intervertebral discs, lack of nutrients, and unhealthy lifestyles. Methods: The machine consisted of two main parts: the spine-like structure (upper portion) and the supporting structure for the lumbar region (lower portion). The upper portion uses four motors to power the rotational motion of the machine. The lower portion uses two parallel screws to transfer the motor’s rotational motion into vertical motion. Results: If the maximum range of rotation of the two motors in the lower portion was set to 800 (rotation units), the pushing force provided by the structure would approach 187.5 Newtons in an ideal situation (when the batteries were fully charged). Conclusions: Experiments have shown that adopting rational sitting postures is beneficial for patients and potential risk-takers, both through active posture adjustments and passive changes (provided by the exoskeleton).
