The Efficacy and Safety of Shoulder Chuna on in Patients with Shoulder Pain Caused by Traffic Accidents

This study is a double blind, randomized controlled trail. condition/disease: Patient with acute shoulder pain and restricted movement due to a traffic accident. treatment/intervention: Chuna therapy for the shoulder, including integrated Korean medicine treatment

The investigators intend to conduct a randomized controlled trial to evaluate the effectiveness of Chuna therapy for shoulder pain and restricted movement caused by a traffic accident. The study will involve administering shoulder Chuna therapy from the second day of hospitalization until discharge, with the aim of assessing its effects on shoulder pain relief and recovery of range of motion. Although the effectiveness of Korean medicine for treating trauma from traffic accidents has been well studied, the research has largely focused on spinal conditions, such as those affecting the cervical and lumbar spine. Likewise, most studies on Chuna therapy have centered around spinal disorders. Through this study, the investigators aim to explore the therapeutic effects of shoulder Chuna therapy, an area that has not been extensively researched.

1. The effectiveness of shoulder Chuna therapy will be evaluated by observing and comparing changes in pain, range of motion limitation, functional disability, quality of life, and patient satisfaction between the shoulder Chuna group (treatment group) and the Korean integrative medicine group (control group).
2. Investigators will assess the treatment effects of shoulder Chuna therapy on shoulder pain and restricted movement by observing improvements in initial NRS, VAS scores, SPADI, and ROM in the shoulder Chuna group (treatment group) compared to the Korean integrative medicine group (control group).
3. The total number of treatment sessions and the degree of improvement will be observed and compared between the shoulder Chuna group (treatment group) and the Korean integrative medicine group (control group) to evaluate the effectiveness of the treatment frequency.
4. The safety of the therapy will be assessed by investigating adverse reactions in both the shoulder Chuna group (treatment group) and the Korean integrative medicine group (control group).

Eligibility Criteria:
Inclusion Criteria:

* Patients aged 19-69 years on the date they sign the consent form.
* Patients with shoulder pain and restricted movement occurring within 5 days after a traffic accident.
* Patients who are hospitalized due to traffic accident.
* Patients with NRS of shoulder pain ≥ 5 with restricted movement due to a traffic accident.
* Patients who provide consent to participate in the trial and return the informed consent form.

Exclusion Criteria:
