Официальное название
Evaluation of the Biomechanics of Crowding and the Energetic Cost of Endurance Runners Unilateral Transtibial Amputees According to the Stiffness of the Race-specific Prothesis.
Обзор
Transtibial amputation accounts for 3,700 cases per year in France. Athletes can use sport blades made of carbon plate for improved energy restitution. Sports blades are adjusted according to the manufacturer's recommendations and the subjective experience of the ortho-prosthetist and patient. These adjustments are designed to optimize performance and comfort while reducing the risk of injury. This risk is all the greater when asymmetries between the healthy and affected limbs are large, exposing the healthy limb to large and repeated reaction forces.
Подробное описание
Furthermore, one of the performance criteria for long-distance running is energy cost. While a reduction in this parameter has been observed in bilateral amputees, heterogeneous data are reported in unilateral amputees, depending on the level of expertise and sports blade settings.
While studies have investigated the effects of running with a prosthesis under conditions representative of track running, few data are available on sports blades designed for long-distance running.
It therefore seems important to be able to objectively assess the effects of a change in the stiffness of the sports blade on the energetics and biomechanics of running, in order to optimize practice and prevent associated traumas.
Secondly, investigators believe it is important to verify that the biomechanical results obtained in the laboratory are applicable in the field, both on the road and on the unstable terrain encountered by trail runners.
