Clinical efficacy evaluation of needle-knife for lumber disc herniation based on surface electromyography signals / 中国针灸

<p><b>OBJECTIVE</b>To apply needle-knife to treat lumber disc herniation (LDH) and surface electromyography were used to analyze biomechanical characteristic of patient's lumber muscle to make a comprehensive evaluation on its efficacy.</p><p><b>METHODS</b>Thirty patients who met the inclusive criteria were selected and treated with needle-knife, once a week for 2 weeks. Visual analogue scale (VAS), ASLR and JOA score before and after treatment were observed. Surface electromyography was applied to test the surface electromyography signals. AEMG, MFs and MPF were calculated before and after the treatment.</p><p><b>RESULTS</b>After treatment, VAS was significantly reduced, ASLR, JOA, AEMG and MPF were obviously increased, and the absolute value of MFs was lowed (all P < 0.01).</p><p><b>CONCLUSION</b>The needle-knife could significantly relieve lumbar muscle strength, muscle tone and muscle fatigue, improve in the imbalance of lumbar extensor muscle group, leading to the recovery of biomechanical characteristic, and the clinical efficacy is superior.</p>

Extracorporeal cardiac shock wave therapy for treatment of coronary artery disease / 中华心血管病杂志

<p><b>OBJECTIVE</b>To evaluate the feasibility and efficiency of extracorporeal cardiac shock wave therapy (CSWT) for treatment of coronary artery disease.</p><p><b>METHODS</b>Twenty-five patients with 1 - 16 years history of chronic angina pectoris underwent the CSWT. Before and after the treatment, low-dose Dobutamine stress echocardiography and (99)Tc(m)-MIBI myocardial perfusion SPECT were applied to locate the ischemic segments, detect the viable myocardium and evaluate the effect of CSWT. Under the guidance of echocardiography, CSWT was applied in R-wave-triggered manner with low energy (0.09 mJ/mm(2)) at 200 shoots/spot for 9 spots (-1-0-+1 combination). Patients were divided group A and group B. Sixteen patients in group A were applied 9 sessions on 29 segments within 3 month and nine patients in group B were applied 9 sessions on 13 segments within 1 month. Ten chronic angina pectoris patients receiving standard medication served as controls.</p><p><b>RESULTS</b>All patients completed the 9 sessions without procedural complications or adverse effects. CSWT significantly improved symptoms as evaluated by NYHA, Canadian Cardiovascular Society (CCS) class sores, Seattle angina questionnaire (SAQ), 6-min walk and the use of nitroglycerin (P < 0.05). CSWT also improved myocardial perfusion and regional myocardium function as evaluated by rest SPECT and stress peak systolic strain rate (PSSR) (P < 0.01). Myocardial perfusion improvement was more significant in group A compared with group B (1.21 ± 0.86 vs. 0.83 ± 0.80, P < 0.01). All parameters remained unchanged in control group during follow up.</p><p><b>CONCLUSION</b>These preliminary results indicate that CSWT is safe and effective on ameliorating anginal symptoms for chronic angina pectoris patients.</p>
