Association Between Running Shoe Characteristics and Lower Extremity Injuries in United States Military Academy Cadets.

Background: Running-related overuse injuries are very common among recreational runners, with the reported annual injury rates ranging from 39% to 85%. Relatively few large prospective cohort studies have been conducted to investigate injury risk associated with different running shoe characteristics, and the results of the existing studies are often contradictory.

Purpose/hypothesis: The purpose was to investigate the relationship between running shoe characteristics and lower extremity musculoskeletal injury.

Predictors of web-based follow-up response in the Prevention Of Low Back Pain In The Military Trial (POLM).

Background: Achieving adequate follow-up in clinical trials is essential to establish the validity of the findings. Achieving adequate response rates reduces bias and increases probability that the findings can be generalized to the population of interest. Therefore, the purpose of this study was to determine the influence of attention, demographic, psychological, and health status factors on web-based response rates in the ongoing Prevention of Low Back Pain in the Military (POLM) trial.
