简要总结
The purpose of this study is to investigate the effects of muscle fatigue in the scapular kinematics of overhead athletes with and without using a kinesio taping technique for facilitating lower trapezius function. The hypothesis is that the taping technique could compensate for the negative effects caused by muscle fatigue in the scapular kinematics of healthy overhead athletes.
详细描述
Muscle fatigue is a potential cause of shoulder injuries in overhead athletes. Considering the important role of lower trapezius for functional scapular stability, it is suggested that a kinesio taping technique for facilitating its function could compensate for the negative effects of muscle fatigue on scapular kinematics. This is a randomized crossover study and all included athletes will be evaluated in three sessions, with a period of seven days between them: Control (fatigue protocol, without taping), Kinesio Taping (fatigue protocol with elastic taping applied with tension) and Sham (fatigue protocol with taping applied without tension). During each session, tridimensional kinematics of scapula and humerus and electromyography of serratus anterior and trapezius (upper and lower portions) muscles of dominant shoulder will be evaluated, during scaption and throwing movements, immediately before and immediately after the fatigue protocol.The changes in scapular movements (before versus after the fatigue protocol) will be compared among the sessions.

结局指标
主要结局
Changes in scapular internal/external rotations, upward/downward rotations and anterior/posterior tilt movements
时间窗: An average of 3 minutes before and an average of 3 minutes after the fatigue protocol, in each of the 3 evaluation sessions.
Scapular 3D kinematics will be measured during arm elevation and throwing movements, in two moments (an average of 3 minutes before and an average of 3 minutes after the fatigue protocol) in each one of the 3 sessions. The evaluation session will have and interval of 7 days between them, and in each one the athletes will perform the fatigue protocol using either a kinesio taping application, or a sham application or without using any taping, in random order. The changes in each session (before and after fatigue) will be compared among the sessions (without taping, with kinesio taping application and sham application).
次要结局
- Changes in the median frequency of electromyographic signal from upper and lower trapezius and serratus anterior muscles.(An average of 3 minutes before and an average of 3 minutes after the fatigue protocol, in each of the 3 evaluation sessions.)
