Background:This article describes the development and evaluation of a new medial linkage orthosis to potentially assist paraplegic patients to ambulate.Case description and methods:The orthosis was initially designed using the solid works program and was subsequently evaluated when used by a spinal cord injury subject to test the structure during standing and walking. Gait analysis was used to compare the medial linkage orthosis to a standard hip–knee–ankle–foot orthosis.Findings and outcomes:The results demonstrated improvements in gait velocity, step length, and decreased compensatory motions in the new orthosis compared to the hip–knee–ankle–foot orthosis.Conclusions:The results propose that this new Araz medial linkage orthosis could be used to assist paraplegic subjects who have adequate ranges of motion and also with weakness or reduced tone to stand and walk.Clinical relevanceThe Araz medial linkage orthosis can potentially provide standing and walking assistance for spinal cord injury patients.

The majority of the people with incomplete spinal cord injury lose their walking ability, due to the weakness of their muscle motors in providing torque. As a result, developing assistive devices to improve their conditionis of great importance. In this study, a combined application of the saddle-assistive device (S-AD) and mechanical medial linkage or thosis was evaluated to improve the walking ability in patients with spinal cord injury in the gait laboratory. This mobile assistive device is called the saddle-assistive device equipped with medial linkage or thosis (S-ADEM). In this device, a mechanical orthosis was used in a wheeled walker as previously done in the literature. Initially, for evaluation of the proposed assistive device, the experimental results related to the forces and torques exerted on the feet and upper limbs of a person with the incomplete Spinal Cord Injury (SCI) during walking usingthe standard walker were compared with an those obtained from using the S-ADEM on an able-bodied subject. It was found that using this combination of assistive devices decreases the vertical force and torque on the foot at the time of walking by 53% and 48%, respectively compared to a standard walker. Moreover, the hand-reaction force on the upper limb was negligible instanding and walking positions usingthe introduced device. The findings of this study revealed that the walking ability of the patients with incomplete SCI was improved using the proposed device, which is due to the bodyweight support and the motion technology used in it.
