A Modified Chair Technique for Acute Anterior Shoulder Dislocation Compare With Traction-counter Traction Technique
A study testing Modified chair technique and Traction-counter traction technique in people with Anterior Shoulder Dislocation, run by Khon Kaen Hospital at 1 site in Thailand.
Trial summary
Anterior shoulder dislocation is the most common type of joint dislocation and requires timely and effective closed reduction. The traction-counter traction technique is widely used in Thailand, although it may require patient transfer and sedation, which can increase the risk of adverse events. Read more about this study

About this study
Official title: A Modified Chair Technique for Acute Anterior Shoulder Dislocation Compare With Traction-counter Traction Technique : A Randomized Controlled Trial
Anterior shoulder dislocation is the most common type of joint dislocation and requires timely and effective closed reduction. The traction-counter traction technique is widely used in Thailand, although it may require patient transfer and sedation, which can increase the risk of adverse events. The modified chair technique has been introduced as a simpler, potentially more convenient method that may allow reduction to be performed in a single location
- Conditions
- Anterior Shoulder Dislocation
- Being tested
- Modified chair technique, Traction-counter traction technique
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Modified chair techniqueProcedure or surgery
Modified Chair Technique is a closed reduction method for acute anterior shoulder dislocation that adapts the traditional chair technique to improve convenience and safety in the emergency setting. Instead of using a standard chair backrest, this modified approach utilizes the side rail of a patient transport stretcher, which serves as a stable fulcrum beneath the patient's axilla.
Traction-counter traction techniqueProcedure or surgery
Traction-Counter Traction Technique is applying longitudinal traction to the affected arm while simultaneously providing counter traction across the patient's torso, allowing controlled separation of the humeral head from surrounding soft tissues to facilitate reduction.

| traction-counter traction teahnique | Active comparator | Not described Receives: Procedure: Traction-counter traction technique |
What is being measured
The primary outcome is the main question the study is designed to answer.
To compare the success rate of shoulder reduction between the modified chair technique and the traction-counter traction technique in patients with acute anterior shoulder dislocation.
Measured: immediate after procedure
Secondary outcomes (2)
To compare the level of pain during the shoulder reduction procedure between the modified chair technique and the traction-counter traction technique.
we record pain with visual analog scale range from 0 to 10
Measured: immediate after procedure
Evaluate the complications associated with shoulder reduction from using the modified chair technique and the traction-counter traction technique.
Complication such as brachial plexus injury, proximal humerus fracture, muscle spasm
Measured: 30 minute after procedure

Questions about this trial
What is this clinical trial studying?
A study testing Modified chair technique and Traction-counter traction technique in people with Anterior Shoulder Dislocation, run by Khon Kaen Hospital at 1 site in Thailand.
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 4 inclusion and 4 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: finished, as of the sponsor's last update on 24 Dec 2025. 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 Thailand. 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. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To compare the success rate of shoulder reduction between the modified chair technique and the traction-counter traction technique in patients with acute anterior shoulder dislocation. (time frame: immediate after procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
