February 16, 2024 updated by: University Fernando Pessoa

Acute Effects of Static Stretching on the Shoulder Joint Position Sense of Overhead Athletes: a Randomized Crossover Trial

The purpose of the study is to investigate the acute effects of static stretching on the shoulder joint position sense of overhead athletes.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A crossover randomized controlled trial will be conducted with 17 overhead athletes (9 males and 8 females). All of them will perform the 3 study conditions in random order: a control (5-minute rest), and static stretching of 30 or 90 seconds of muscles around the shoulder. The shoulder joint position sense will be assessed before and immediately after these conditions, and tested by active repositioning for the range of 110º of flexion, with a video camera. Absolute, relative and variable angular errors will be calculated.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Subjects aged between 18 and 30 years
  • Competitive overhead athletes (basketball, handball, volleyball, swimming)
  • Normal range of motion of flexion of the shoulder

Exclusion Criteria:

  • History of injury of the shoulder joint in the previous 6 months
  • Positive shoulder joint integrity tests (anterior drawer; fulcrum test; Jerk test; and sulcus sign)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Control Condition
5-minute rest.
Active Comparator: Static Stretching of 30 seconds Condition

Static stretching of 30 seconds of muscles around the shoulder of the dominant upper limb:

  • Shoulder extension - shoulder extension with the hand resting on a door;
  • Doorway stretch - horizontal abduction with the shoulder in 90º of abduction, the elbow in 90º of flexion and the forearm leaning against a door;
  • Shoulder flexion - arms above the head against a wall;
  • Cross-body stretch - maximal horizontal adduction of the arm, with the opposite hand holding the stretch;
  • Overhead triceps - arm above the head and elbow flexed, with the other hand pulling the elbow;
  • Internal Rotation 90° stretch - with the shoulder at 90º of flexion and the elbow at 90º of flexion, the opposite hand and forearm forces the internal rotation.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Absolute angular error
Time Frame: Change from Baseline (Before) to Immediately after interventions or control (After)
The absolute value of the difference between the target range and the achieved range
Change from Baseline (Before) to Immediately after interventions or control (After)
Relative angular error
Time Frame: Change from Baseline (Before) to Immediately after interventions or control (After)
The arithmetic difference between the target range and the range achieved
Change from Baseline (Before) to Immediately after interventions or control (After)
Variable angular error
Time Frame: Change from Baseline (Before) to Immediately after interventions or control (After)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
