Biomechanical data on most bracing and protective equipment systems is lacking. To better understand the clinical success of counterforce bracing, a biomechanical analysis of braced and unbraced tennis players (serve and backhand strokes) was undertaken. Three-dimensional cinematography and electromyographic techniques were used. Three commonly used counterforce braces (lateral elbow, medial elbow, and radial-ulnar wrist) were compared with the unbraced condition. The overall results basically reveal positive biomechanical alterations in forearm muscle activity and angular joint acceleration dependent upon the brace and joint area analyzed.
大多数支撑和防护装备系统的生物力学数据都很缺乏。为了更好地理解反作用力支撑的临床效果，对佩戴支撑装备和未佩戴支撑装备的网球运动员（发球和反手击球）进行了生物力学分析。使用了三维摄影和肌电图技术。将三种常用的反作用力支撑护具（外侧肘部、内侧肘部和桡尺腕部）与未佩戴支撑护具的情况进行了比较。总体结果基本上显示，根据所分析的护具和关节区域不同，前臂肌肉活动和关节角加速度出现了积极的生物力学变化。
