title: [Clinical observation of different needle retention times for acute lumbar sprain treated with float needle].
abstract: OBJECTIVE
  To observe the difference of the clinical effects of different needle retention times for acute lumbar sprain treated with float needle.
  
  
  METHODS
  One hundred and twenty patients with acute lumbar sprain were randomly divided into a 6 h group, a 12 h group, a 24 h group and a western medication group, 30 cases in each one. In the three float needle groups, plastic hose was detained near the pressure pain point on the lumbar after subcutaneous scattering with float needle. The needle retention time was 6 h, 12 h and 24 h respectively. In the western medication group, 75 mg voltaren tablet was adopted orally every day and the treatment was given for four days. Visual analogue scale (VAS) and Oswestry dysfunction index (ODI) about low back pain were observed before and after treatment. Also, the comprehensive effect was assessed after treatment.
  
  
  RESULTS
  After treatment, the VAS scores and the ODI scores were improved obviously than those before treatment in all groups (all P< 0. 05). In the three float needle groups, the VAS scores and the ODI scores were superior to those in the western medication group (all P<0. 05). The differences in VAS scores and ODI scores among the three float needle groups were not statistically significant after treatment (all P>0. 05). The effective rate in the 6 h, 12 h and 24 h group was 93. 3% (28/30), 90. 0% (27/30) and 93. 3% (28/30) respectively, which were better than 73. 3% (22/30) in the western medication group (all P<0. 05).
  
  
  CONCLUSIONS
  The effect of float needle for acute lumbar sprain is better than voltaren, and there is no apparent difference in retention times.
