The Efficacy and Safety of Shoulder Motion Style Acupuncture Treatment (MSAT) on in Patients With Shoulder Pain Caused by Traffic Accidents

This study will test the effectiveness and safety of Motion Style Acupuncture Treatment (MSAT) for shoulder pain caused by traffic accidents. About 98 hospitalized patients with acute shoulder pain after a traffic accident will take part. Participants will be randomly assigned to one of two groups: MSAT + integrative Korean medicine group (acupuncture, herbal medicine, pharmacopuncture, Chuna therapy, plus MSAT), or Integrative Korean medicine only group (acupuncture, herbal medicine, pharmacopuncture, Chuna therapy). MSAT involves inserting needles into the shoulder area and gently moving the joint to improve pain relief and mobility. All treatments used in this study are standard care in Korean medicine. The main outcomes are pain reduction, shoulder movement, daily function, quality of life, and patient satisfaction. Safety will also be monitored by recording any side effects such as temporary soreness, bruising, or discomfort. Treatment will be provided during hospitalization (up to 5 days), and patients will be followed up by phone at 2 weeks and 1 month after enrollment. The results of this trial will help determine whether adding MSAT to standard integrative Korean medicine treatment provides greater benefit for patients with acute shoulder pain after traffic accidents.
