In the US over half a million people are prescribed crutches each year. More than 750,000 wheelchair users exist in the UK and wheelchair and crutch users commonly develop shoulder pathology. The purpose of this study was to determine the influence of complex topographies on heart rate (HR) and thus energy expenditure, using a wheelchair and differing crutch designs on the exertional body stress. Two Paralympics Athletes from the GB amputee football squad were assessed in a Lomax Active wheelchair and 5 different types of crutches in a randomly allocated order over a course representing everyday complex terrains at the Pedestrian Accessibility and Movement Environment Laboratory (PAMELA), University College London. In addition results were compared over the same course with the athletes using their own personal pair of crutches. The PAMELA course consisted of a mixture of 4% and 2.5% cross falls (transverse) and a simulated road crossing, sprint, slalom and a slow straight.Introduction
