About this study
Non-resistance therapy is a combination of muscle compression relaxation technique and joint mobilization in patients with acute neck pain caused by traffic accidents. This study is to evaluate the effectiveness and safety of non-resistance therapy for pain and function problems in patients complaining of acute neck pain induced by traffic accidents.
So, investigators conduct a randomized controlled trials to verify the effectiveness and safety of non-resistance therapy. From December 2020 to May 2021, investigators recruit 120 inpatients who are suffered from acute neck pain with the numeric rating scale(NRS) over 5 by traffic accident(TA).

The Korean medical treatment group(n=60) receives daily acupuncture, herbal medicine, and chuna treatment as inpatient treatment from hospitalization until discharge. For the non-resistance therapy group(n=60), the korean medical treatment is performed in the same manner, but additional non-resistance therapy is performed once a day from the 2nd day to the 5th day of hospitalization.
Baseline is the time point before treatment for non-resistance therapy on the second day of hospitalization, and the primary endpoint is the time point after treatment on the 5th day (v5) after hospitalization.
For these two groups, investigators compare NRS(Numeric Rating Scale), Visual Analogue Scale(VAS), Range Of Motion(ROM), Neck Disability Index(NDI), the 12-Item Short Form Health Survey(SF-12), and PTSD Checklist for DSM(Diagnostic and Statistical Manual of Mental Disorders, DSM)-5(PCL-5).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
non-resistance therapyOther
The non-resistance technique, created in Jaseng Hospital, is a combination of ischemic compression and mobilization It is a treatment that improves the limited range of motion of the cervical spine and relieves pain by applying ischemic pressure to the induration of the neck and at the same time firmly supporting the patient's head to give passive joint movements and completely relax.
acupunctureOther
According to the judgment of the oriental medicine doctor, select acupuncture point and tender spots such as BL10, TE14, GB20, GV16, etc. to a depth of 10 mm 6 -Self needle in 12 blood spots.
chunaOther
Chuna treatment is administered once a day during the hospitalization period. Chuna is Korean manual therapy using methods such as joint mobilization, joint distraction, fascia relaxation and manipulation.
pharmacoacupunctureOther
This is an oriental medical practice in which a certain amount of a drug extracted from a specific herbal medicine is injected with an injector to treat the patient's constitution, disease state, etc., and then injected into the treatment acupuncture points and body surface reaction points. Depending on the condition of the inpatient, acupuncture is used in parallel.

What is being measured
The primary outcome is the main question the study is designed to answer.
Numeric Rating Scale(NRS) of neck pain
The extent of acute neck pain and discomfort was assessed using NRS. NRS is a pain scale in which the patient indicates their subjective pain as a whole number from 0 to 10. The participants are asked to report their neck pain and discomfort using NRS, where 0 indicates 'no pain or discomfort' and 10 indicates 'the most severe pain and discomfort imaginable'.
Measured: Change from baseline NRS at 5 days

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Non-resistance therapy is a combination of muscle compression relaxation technique and joint mobilization in patients with acute neck pain caused by traffic accidents. This study is to evaluate the effectiveness and safety of non-resistance therapy for pain and function problems in patients complaining of acute neck pain induced by traffic accidents.
So, investigators conduct a randomized controlled trials to verify the effectiveness and safety of non-resistance therapy. From December 2020 to May 2021, investigators recruit 120 inpatients who are suffered from acute neck pain with the numeric rating scale(NRS) over 5 by traffic accident(TA).
The Korean medical treatment group(n=60) receives daily acupuncture, herbal medicine, and chuna treatment as inpatient treatment from hospitalization until discharge. For the non-resistance therapy group(n=60), the korean medical treatment is performed in the same manner, but additional non-resistance therapy is performed once a day from the 2nd day to the 5th day of hospitalization.
Baseline is the time point before treatment for non-resistance therapy on the second day of hospitalization, and the primary endpoint is the time point after treatment on the 5th day (v5) after hospitalization.
For these two groups, investigators compare NRS(Numeric Rating Scale), Visual Analogue Scale(VAS), Range Of Motion(ROM), Neck Disability Index(NDI), the 12-Item Short Form Health Survey(SF-12), and PTSD Checklist for DSM(Diagnostic and Statistical Manual of Mental Disorders, DSM)-5(PCL-5).
