Experimental investigation of applying segmented scoop stretcher (S3) for full-body immobilization of the injured patient

Abstract

The work presents an experimental investigation of a novel segmented scoop stretcher (S3) to examine full-body immobilization during patient transfer. The designed stretcher aids to provide head, vertebral column, and pelvis immobilization during segmented scooping of corresponding body parts. Scooping experiments on nine participants were performed on fabricated S3 and one of the commercially available scoop stretcher (CSS) to compare the mean range of motion (ROM) of various body parts employing full body scissor and segmented scissor techniques. The angular motion along the spinous process and the nasion (forehead) were recorded through motion sensors (six-dimensional electromagnetic tracking system) placed at various anatomical positions while scooping. Experimental results showed a significant reduction in movement of corresponding body parts in scooping with S3 as compared to existing CSS. A higher immobilization of approximately 2º–5º in the sagittal, lateral, and axial planes were observed while applying S3 as compared to CSS ( p < 0.002). Achieving improvement in immobilization of the injured patient with S3 can reduce the risk of further injury during pre-hospital care.
