Injury Prevention Effectiveness of Modifications of Shoe Type on Injuries and Risk Factors Associated with Pain and Discomfort in the US Army Band, Fort Meyer, Virginia 2007-2008

摘要

Footwear characteristics can have an influence on fatigue, overuse injuries and comfort. Shoes are an important consideration for members of the US Army Band who may perform hundreds of missions a year. These missions often include prolonged standing, marching, and can be conducted in unfavorable weather conditions. In a previous investigation, over 50% of the band members noted problems with their footwear such as lack of cushioning, support and breathability. In an effort to reduce injuries and improve comfort, one to two pairs of shoes with a presumed increase in cushioning and ventilation were provided to the band members (n=112) to wear for one year. Participant demographic and lifestyle data were collected from existing databases and a questionnaire. The McNemar test was used to compare injury incidence 1 year prior to receiving the shoes and 1 year after receiving the shoes. Potential risk factors for self-reported foot, knee, and back pain, numbness or discomfort attributed to band activities were explored using logistic regression. There were no differences in injury incidence one year before receiving the new shoes versus the year in which the band members wore the new shoes. Being assigned to the ceremonial group, poor shoe cushioning, wearing orthotics and those who replaced their shoes more frequently were associated with a higher risk of foot pain and discomfort; a poor fit in the heel was associated with a higher risk of knee pain and discomfort; marching for longer periods of time, performing other physical activities 5-7 days a week, poor shoe cushioning and reported feet too warm in hot weather was associated with a higher risk of back pain and discomfort. Combining the specific shoe characteristic ratings into groups revealed that approximately a quarter of the band members rated the fit of the shoes as poor and approximately one third rated comfort characteristics as poor.
