The Evaluation of Single Acupoint Therapy to Acute Low Back Pain

Study Overview
=================
Brief Summary
-----------------
Low back pain is the leading course of disability , affecting patients' health and work. Recently, studies have reveal the fact that patients get insufficient physical activity and easily let acute stage turn to chronic type. Although acupuncture for low back pain is worldwide popular, the mechanism of single acupoint for low back pain is still unclear. Therefore, the aim of this study is the investigators choose the most frequent used acupoint and modified single acupoint method to assess the efficacy of single acupoint to acute low back pain.

Detailed Description
-----------------
Low back pain is the leading course of disability , affecting patients' health and work. According to the study in 2013, 8.9 percent people of the world experienced over three months low back pain. Recently, studies have reveal the fact that patients get insufficient physical activity and easily let acute stage turn to chronic type. Although acupuncture for low back pain is worldwide popular, the mechanism of single acupoint for low back pian is still unclear. Therefore, the investigators choose the most frequent used acupoint and modified single acupoint method to assess the efficacy of single acupoint to acute low back pain. The investigators would like to compare the efficacy of the modified Bladder 40 (BL40) acupuncture to single acupoint through statistical analysis. The investigators expect that all group will alleviate low back pain. However, treatment group will have statistical difference compared with control groups. The aim of this study is the investigators choose the most frequent used acupoint and modified single acupoint method to assess the efficacy of single acupoint to acute low back pain.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| pain measurement | use Visual Analogue Scale to measure pain intensity and algometer to measure pain threshold The minimum of Visual Analogue Scale is 0 and maximum values is 10. The higher Visual Analogue Scale mean a worse outcome . Newton is used to measure pain threshold. The higher pain threshold scores mean a better outcome . | 30 minutes | 
| range of motion measurement | measure the range of motion when lumbar extension and flexion | 30 minutes |
