Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control

In this session, the athletes will be evaluated before and after the fatigue protocol, without any taping application.

Group Type OTHER

Fatigue protocol

Intervention Type OTHER

Kinesio taping

A kinesio taping technique for facilitating lower trapezius muscle function will be applied just before fatigue protocol and removed after in the end of the evaluation session.

Group Type EXPERIMENTAL

Elastic taping applied with tension

Intervention Type OTHER

Fatigue protocol

Intervention Type OTHER

Sham

A similar technique, using the same tape, will be applied but without any tension (tension is considered to be the therapeutic effect). The tape will be applied just before the fatigue protocol and removed in the end of the session.
