About this study

Official title: Effects of Muscle Fatigue and Scapular Taping on Shoulder Kinematics of Overhead Athletes

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.

Read the detailed description

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 groupRoleWhat they receive
ControlOtherIn this session, the athletes will be evaluated before and after the fatigue protocol, without any taping application.
Receives: Other: Fatigue protocol
Kinesio tapingExperimentalA 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.
Receives: Other: Elastic taping applied with tension; Other: Fatigue protocol
ShamSham comparatorA 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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).

    Measured: 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)
  1. Changes in the median frequency of electromyographic signal from upper and lower trapezius and serratus anterior muscles.

    Electromyographic median frequency will be measured from upper and lower trapezius and serratus anterior muscles in order to determine muscle fatigue development and if the changes depending on the intervention used. These assessments will be performed 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(with an interval of 7 days between them). In each session 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).

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

Questions about this trial

What is this clinical trial studying?

A study testing Elastic taping applied with tension, Elastic taping applied without tension and Fatigue protocol in people with Shoulder Injury and Muscle Fatigue, run by Universidade Federal de Sao Carlos at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 2 Apr 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Gisele G Zanca, MSc (55 16 33519579, gisele_gz@yahoo.com.br), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in scapular internal/external rotations, upward/downward rotations and anterior/posterior tilt movements (time frame: An average of 3 minutes before and an average of 3 minutes after the fatigue protocol, in each of the 3 evaluation sessions.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Apr 2013.
