| Objectives:1. To compare paraspinal muscle activity as measured by electromyography (EMG) of patients with ankylosing Spondylitis (AS) and healthy volunteers. And also measured the finger-floor distance, pulvinar-wall distance, Schober test results, level of fatigue and pain, and to investigate the value of EMG in the evaluation of therapeutic efficacy on patients with AS.2. Electromyography about silver needle acupuncture treatment in patients with ankylosing Spondylitis, evaluate the therapeutic efficacy. To investigate the value of silver needle acupuncture treatment in clinical application.Materials and Methods:data and case 32 patients of AS come from traditional Chinese medicine orthopedics and rheumatic division of Nanfang hospital. 32 healthy volunteer come from medical examination center of Nanfang hospital.Internalize standard To accord with revised standard in New York in 1984. Unremitting and intermittent pain from low back, it last more than three months. Limitation of activity in lumbar spine. Bony thorax enlargement diminutive than the normal value of the similar age and sex.Two sides sacroilitis ofⅡ～Ⅳcaste, or half sacroilitis ofⅢ～Ⅳcaste. If patient to have three of these, then it may final diagnosis for AS.Exclusion standard Less than sixteen years old and exceed sixty years old. Femme who at encyesis or lactation. The one who complicating disease of Cerebral vessels. The X-ray showed the joint space of dorsal spine had been abolition. Parameters and measures:1. Check of EMG: In the shielded enclosure with temperature at 25℃,the meter of electromyogram Nicolet VikingⅣwas made in American. All the subjects detected the paraspinal muscle by cocenric citcle electrode. Step of detection: First, all the subjects with prone position, indicated the location of L1,L4 in pars lumbalis. By means of 2cm aside linea mediana as needling point of EMG exam. Second, after the needle electrode degermed, needling verticality, the indicatrix of observation were the latitude and wave amplitude of motor unit potential(MUP).2. Other parameter index: finger-floor distance; pulvinar-wall distance,;Schober test results; level of fatigue and pain.Cases and Grouping:1. Thirty-two patients with AS as disease group. And 32 healthy volunteers as normal control group. All of them received EMG checking.2. Thirty-two patients with AS fractionate two sets trabantly. One set received simple drug healing, the other received drug and silver needle acupuncture treatment. Detected all the patients before and after treatment.Statistical methods Compared with two means on t test of independent sampler. Compared before and after treatment on t test of paired-sampler. Bivariation normal distribution data adoption the Pearson correlation, un-bivariation normal distribution data adoption the Spearman correlation. Confidence interval was 95%, P < 0.05 had significant difference.Results:1. EMG activity was significantly lower in patients with AS than in the controls(P<0.01).The shorten of latitude and decline of amplitude appeared in the EMG of the AS group after contraction with little strength. It was found that EMG activity was highly correlated with the Schober test results and the level of pain(P<0.01).2. The value of each detection before and after simple drug treatment were significant difference(P<0.01). The value of each detection before and after drug and silver needle acupuncture treatment are also significant difference(P<0.01).Conclusion:1. EMG can effectively reflect paraspinal muscle activity and spinal mobility, what could be an effective way to evaluat of therapeutic efficacy on patients with AS.2. Level of fatigue and pain could be treated by simple drug treatment both drug and silver needle acupuncture treatment. Myoelectrictty index and dorsal spine function also improved by drug and silver needle acupuncture treatment. The curative effect of this method was exact, it deserved to extend in clinical application. |
