This study is a double blind, randomized controlled trail. condition/disease: acute low back pain treatment/intervention: motion style acupuncture treatment

Motion Style Acupuncture Treatment(MSAT) is a therapeutic technique using acupuncture needle created in Jaseng Hospital. This treatment involves patients with musculoskeletal pain to move the part of their body actively during acupuncture treatment under physicians' observation. This treatment is known to relieve the pain and increase the range of motion(ROM). However, there has been no specific value for the effect of this treatment.

So, the investigators conducted a randomized controlled trials to verify the efficacy and safety of Sandbag MSAT. From June 2021 to June 2023, the investigators collected 104 inpatients who were suffered from Low back pain with the numeric rating scale(NRS) over 5 after injury by acute traffic accident(TA). For experimental group(n=52), the investigators conducted MSAT three times(on 2nd, 3rd and 4th day of hospitalization) and other Korean medical treatment. For control group(n=52), just Korean medical treatment except MSAT was conducted. For these two groups, the investigators compared NRS, Visual Analogue Scale(VAS), Range Of Motion(ROM), the amount of pain via NRS(Numeric Rating Scale), VAS(Visual Analogue Scale), ROM(Range Of Motion), Oswestry Disability Index (ODI), and EuroQol 5-Dimension (EQ-5D), EuroQol Visual Analogue Scale (EQ-VAS), Short Form-12 Health Survey version 2, SF-12 v2), The Posttraumatic Stress Disorder Checklist for DSM-5(PCL-5-K), Patient Global Impression of Change (PGIC).
