Influence of a Viscoelastic Insole on Foot, Knee and Back Pain among Members of the United States Army Band.

摘要

Standing and marching have been associated with musculoskeletal pain of the feet as well as discomfort and fatigue of the back and lower extremities. U.S. Army Band members spend hundreds of hours a year standing and marching. To see if musculoskeletal pain could be reduced, one pair of viscoelastic silicone insoles were provided to band members (n=69). These insoles incorporated a metatarsal pad, ventilation holes for circulation, and a slight contour in the arch support area. Before the insoles 48% and 45% of band members reported foot and back pain, respectively. After using the insoles, for at least 50% of the time or greater, 28% and 26% (p=0.02 and 0.04) of band members reported foot and back pain, respectively. After adjusting for correlated outcome data and initial differences, band members were 74% and 59% less likely to have foot and back pain, respectively, after wearing the insoles for 8-12 weeks. It is recommended that band members use insoles to reduce musculoskeletal pain.
