Abstract

Functional knee braces are commonly used in the athletic realm in an attempt to prevent initial and reoccurring injuries. The purpose of this study is to evaluate muscular activity in collegiate football linemen during sport specific skills (three point stance, lateral cutting maneuver, and drop jump). Ground Reaction force (GRF) and muscular activity of the quadriceps and hamstrings was analyzed to determine the impact of wearing a knee brace. Results showed no differences in the GRF or muscular activity of the quadriceps during any of the skills. The hamstring showed increased activity drop jump only. In conclusion, functional knee braces do not negatively impact muscular activity during football specific drills.

These video clips demonstrate cutting maneuvers and muscular activity as discussed in this presentation.

Muscular Activity in Collegiate Football Linemen with and without a Prefabricated Functional Knee Brace
