A Clinical Randomized Controlled Study Of Centro-square Needling Method For Chronic Lumbar Muscle Strain

Objective:To study clinical effects between centro-square needling and the conventional acupuncture in treating chronic lumbar muscle strain.Methods:62cases with chronic lumbar muscle strain were randomly divided into treatment group (treated by centro-square needling) and controlled group (treated by conventional acupuncture). Record the data before and after treatment, clinical effects evaluated via clinical symptom scores, clinical sign integral, TCM symptom score and SF-36Scale.Results:(1) Baseline analysis:sex, age, course, clinical symptom scores, clinical sign integral, TCM symptom score and SF-36Scale were of no statistic significance (p>0.05).(2) Comparison of clinical effects between the two groups after the treatment:Comparison of The total curative effect:the total effective rate was96.7%in the treatment group, while the rate was correspondently89.7%in the controlled group. The difference of total curative effect between the two groups was of statistic significance (p<0.05). Comparison of clinical symptom scores:pain intensity, cold pain, heavy sensation or soreness, numbness, intension of pain, dull pain and soreness, continuously-fixed pain, the nature of pain and clinical symptom scores were of statistic significance (p<0.05), with pain status being of no statistic significance (p>0.05). Comparison of clinical sign integral:tenderness in lumbar, number of the tender point and clinical sign integral were of statistic significance (p<0.05), with limitation of movement scores being of no statistic significance (p>0.05). TCM symptom score and SF-36Scale were of no statistic significance (p>0.05).(3) Comparison in two groups before and after treatment:clinical symptom scores, clinical sign integral, TCM symptom score and SF-36Scale were of obvious statistic significance (p<0.01).Conclusion:(1) Both of two methods could improve patients’clinical symptoms, clinical signs, TCM symptom and quality of life.(2) The treatment group was better than the controlled group in improving clinical symptoms such as pain intensity, cold pain, heavy sensation or soreness, numbness, intension of pain, dull pain and soreness, continuously-fixed pain, the nature of pain and clinical signs such as tenderness in lumbar, number of the tender point. The effect of the two groups was equivalent in improving pain satus, imitation of movement and quality of life.(3) The total curative effect of the treatment group is better than the controlled group.
