The Fair Regulation of Lower-Limb Prostheses Technology in Paralympic Running BRYCE T.J. DYER BA (Hons), MSc SUMMARY OF RESEARCH PROJECT Within sport, there is a constant need to make sure that competition is as fair as possible between its participants. This research project investigates whether this is the case within lower-limb disability running and whether there are any future implications of unfairness through the use of prostheses technology used by its athletes. From a 2008 study, an ethical foundation of values has been developed. This forms the basis for a proposed qualitative/quantitative legislative model for disability running sports technology. The proposed 2 stage model monitors that the athlete remains the main influence on their event success rather than as a result of the prostheses technology they use. SETTING THE ETHICAL FOUNDATION: METHOD & RESULTS (May-Dec 2008) 22 participants undertook a 3 round Delphi Technique process*. This involved anonymous participation of an expert stakeholder panel questioned over a structured iterative process of rounds. The aim of the Delphi technique is in obtaining a shared consensus of opinion in developing or incomplete areas of knowledge. Consensus was defined as a 70% level of agreement between the panel and the absence of a change in opinion between the iterative rounds. The Delphi process conclusions were: The lower-limb running prosthesis is a restorative form of equipment in nature. Increased legislative control and performance limitations should be imposed on the lower-limb prostheses to maintain a fair environment within the specific running discipline. A lower-limb prostheses contribution is defined by the individuals own physical abilities that they have obtained under naturally generated means. *Note: as a result of this research, the author was recently invited to become a member of a new working group within the International Paralympic Committee. PROPOSAL OF FUNCTIONAL ASSESSMENT METHOD (Late 2009) Stage 2 of proposed model:- A functional assessment of the lower-limb prostheses. The specification of this test are based upon the literature review and the findings of the Delphi study. They are: The prosthetic leg must be comparable to the sound limbs functional ability. The compensation effect of the human musculature when using a lower-limb prostheses must be minimised where possible. The tests should be repeatable in a non-laboratory environment and correlate as much as possible with the functional requirements of running. PROPOSAL: The athletes lower-limb prostheses technology will be assessed through use of a uni-lateral limb drop test. The limb to limb outcome measures between a sound limb and a prosthetic limb measured by this method will be leg stiffness and the percentage of energy return (from below the knee only) measured using kinematic methods.
