Biomechanical study of manual wheelchair propulsion by elderly suffering or not from shoulder pain

Imen Khelia
Abstract : The daily use of a manual wheelchair (MWC) implicates for many ageing people, as like for the handicapped young people and/or athletes, an overuse of the anatomical structure of the shoulders. In the long term, this fact is responsible for degenerative and painful phenomena leading to additional expenditure of health. Having a preventive target, the presented researches were done with one object in view: decreasing the stress of the scapulo-humeral girdle during MWC propulsion. A preliminary epidemiological study revealed the increasing of such a problem. In addition, the anatomo-pathological study showed the inefficiency of the health care intended to reduce the shoulder pains. The literature review also revealed the lack of researches concerning many aspects of the MWC propulsion by elderly and amputated population. Initially, a data acquisition system has been conceived to measure the dynamic, kinematic and electromyographic aspects of the MWC propulsion. The reliability of the equipment and the recorded data were both validated. These devices allowed the study of the MWC technique of propulsion by elderly people suffering or not from shoulder pains. The results revealed certain probable causes and consequences of these pains. They will permit to the clinicians to improve the control of a prevention process. These investigations led to the development and the validation of a MWC propulsion prototype, having two main characteristics: inexpensive and adaptable to all the types of MWC. This innovating device consists in an elastic connection between handrims and driving wheels. The experimental analyses and the clinical results revealed the main interests of such as a novel design: amelioration of comfort during the daily use of the MWC and in the reduction of the stresses of upper limb joints. The outcomes of such a research are in the following fields: scientific and technological but also medical, human and economic.
