Randomized Controlled Trial Comparative Study
Do shock absorbing insoles in recruits undertaking high levels of physical activity reduce lower limb injury? A randomized controlled trial.
To assess the benefits, if any, of the use of shock absorbing insoles in reducing lower limb injury among Air Force recruits, and to assess the differences, if any, in the efficacy of two commonly available shock absorbing insoles. ⋯ Similar rates of lower limb injuries were observed for all insoles (shock absorbing and non-shock absorbing) in the trial. The trial provides no support for a change in policy to the use of shock absorbing insoles for military recruits.

Risk assessment can be thought of as the lens through which we anticipate the consequences of research and the impact of the actions of researchers. The way in which risk of harm is managed in research is strongly influenced by the surrounding social and political environment, leading to differences in national and local styles of regulation and review. Different research studies carry different risks, so systems for review and approval must adapt to the question being asked and the nature of the study. Researchers can never wholly guarantee safety in any research but participants and researchers must be offered reasonable protection within any study, with appropriate arrangements in place should something go wrong.
