NCT01764620

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Changes in scapular internal/external rotations, upward/downward rotations and anterior/posterior tilt movements

    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).

    An average of 3 minutes before and an average of 3 minutes after the fatigue protocol, in each of the 3 evaluation sessions.

Secondary Outcomes (1)

  • 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.

Study Arms (3)

Control

OTHER

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

Other: Fatigue protocol

Kinesio taping

EXPERIMENTAL

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.

Other: Elastic taping applied with tensionOther: Fatigue protocol

Sham

SHAM COMPARATOR

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.

Other: Elastic taping applied without tensionOther: Fatigue protocol
