The journal publishes material that is indispensable. Those with lower limb disabilities are often dependent on manually propelled wheelchairs for their mobility, in Europe today some 3.3 million people. This implies a transfer from leg to arm work for ambulation and all other activities of daily living (ADL). Compared to the legs, arm work is less efficient and more straining, and leads to a lower physical capacity. Also, there is a major risk of mechanical overuse. Problems of long-term wheelchair use are not only pain or discomfort, but also a risk of a physically inactive lifestyle. Subsequently, serious secondary impairments (obesity, diabetes and cardiovascular problems) may eventually emerge. Wheelchair quality, including the ergonomic fitting to the individual may play a preventive role here, but also other modes of physical activity, and the understanding of training, rehabilitation.
