End-range Maitland Mobilization on Glenohumeral Internal Rotation Deficit and Proprioception

September 4, 2022 updated by: University of Pecs

The Effect of End-range Maitland Mobilization on Glenohumeral Internal Rotation Deficit and Proprioception in Volleyball Players

Glenohumeral internal rotation deficit (GIRD) is one of the main reasons for glenohumeral pain in athletes with over-head activity. As GIRD increases, the ratio between internal and external rotation changes resulting in decreased joint stability.

Joint mobilization is a possible option for the decrease of GIRD and contribution to improvement of proprioception in addition to physical therapy. The aim of this trial is to investigate the effect of end-range Maitland mobilization in addition to physical therapy on GIRD, other joint movements and proprioception.

Detailed Description

Glenohumeral internal rotation deficit (GIRD) is one of the main reasons for glenohumeral pain in athletes with over-head activity. As GIRD increases, the ratio between internal and external rotation changes resulting in decreased joint stability. The occurence of GIRD and decreased joint proprioception may lead to different shoulder pathologies (e.g. Impingement syndrome).

Joint mobilization is a possible option for the decrease of GIRD and contribution to improvement of proprioception in addition to physical therapy. Several joint mobilization techniques exists, which can be applied for stretching of periarticular tissues. Maitland mobilization is a well applied mobilization type. The effectiveness of both end-range and not end-range Maitland mobilization in lengthening of periarticular tissues and improvement of joint proprioception has been previously confirmed amongst several diseases. However, the effect of end-range Maitland mobilization on decrease of GIRD and proprioception in addition to physical therapy has not been investigated in volleyball players so far.

The aim of this trial is to investigate the effect of end-range Maitland mobilization in addition to physical therapy on GIRD, other joint movements and proprioception.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

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.
