Design of a semi-automatic adjustable standing frame for paraplegics

Abstract:

Introduction: Paraplegia is an impairment in motor functioning of the lower extremities. Caused by lumbar lesions, it deprives its sufferers from their ability to move about, which results in breathing problems, arterial pressure variations and the appearance of ulcers in pressure areas. Objective: Develop a mechatronic system permitting the bipedal locomotion of paraplegics. Methods: The study was structured into two stages: development of a mechatronic system and validation of its use by people with motor disability. Results: Function tests show that the most attractive features of the device are its adjustability (allowing use by anthropometrically different people) and its operability. Conclusions: The standing frame designed met the conditions required for the transition to bipedal condition, with safety measures in its critical parts which ensure user stability. Additionally, its mechanisms are easy to operate, in keeping with its capabilities. Validation of the device showed that its size is appropriate, its operation simple, and it may be readjusted for use in different morphometric conditions.
