Although the use of prophylactic knee braces in football players is common, the effectiveness of this practice is questionable. Some studies have actually shown an increase in the incidence of lower extremity injuries in players wearing such braces. The purpose of this study was to determine if wearing a prophylactic knee brace (Omni Anderson Knee Stabler) caused an alteration in a normal running gait pattern that might then increase the risk for injury. Ten subjects with no prior history of knee injury or brace use were filmed in two planes while running on a treadmill at 5 mph. Two-dimensional digital analysis of each subject's running gait with and without the use of knee braces was performed. The duration of the gait cycle and the range of motion and velocity of movements at the knee, hip, and ankle joints were determined in each leg for each condition. No differences were found between braced and nonbraced conditions for any of the measured variables. Therefore, we conclude that the use of the Omni Anderson Knee Stabler does not alter gait pattern of the lower extremities while running on a treadmill.
尽管在足球运动员中使用预防性膝盖护具很常见，但这种做法的效果值得怀疑。一些研究实际上表明，佩戴此类护具的运动员下肢受伤的发生率增加了。本研究的目的是确定佩戴预防性膝盖护具（Omni Anderson Knee Stabler）是否会改变正常的跑步步态模式，从而增加受伤的风险。10 名受试者无既往膝盖受伤或使用护具的病史，在跑步机上以 5 英里/小时的速度在两个平面上进行拍摄。对每位受试者在使用和不使用膝盖护具时的跑步步态进行二维数字分析。在每种情况下，确定每条腿的步态周期持续时间以及膝关节、髋关节和踝关节的运动幅度和速度。在任何测量变量中，都没有发现支撑和非支撑条件之间存在差异。因此，我们得出结论，在跑步机上跑步时，使用 Omni Anderson Knee Stabler 不会改变下肢的步态模式。
