ABSTRACT
<p><b>OBJECTIVE</b>To compare the effects between mild moxibustion and specific electromagnetic spectrum therapy apparatus (TDP) for obsolete collateral ligament injury of interphalangeal joints.</p><p><b>METHODS</b>Sixty patients were randomly divided into a mild moxibustion group and a TDP group, 30 cases in each one. In the mild moxibustion group, pure moxa sticks were used at the affected digital joints locally for 20-30 min a time. In the TDP group, TDP was applied at the affected digital joints locally for 20-30 min a time. The treatment was given once a day for two courses, and 10-day treatment was made into a course. Visual analogue scale (VAS) for pain, swelling degree of the affected digital joints before and after treatment were observed and the clinical efficacy and safety were evaluated in the two groups.</p><p><b>RESULTS</b>The excellent rate was 56.7% (17/30) and the excellent and, good rate was 83.4% (25/30) in the mild moxibustion group,which were better than 36.7% (11/30) and 76.7% (23/30) in the TDP group respectively (both P < 0.01). After treatment the score of VAS and digital joints swelling degree were improved than those before treatment in the two groups (P < 0.01, P < 0.05), and the improvements of the mild moxibustion group were better than those of the TDP group (P < 0.01, P < 0.05).</p><p><b>CONCLUSION</b>Mild moxibustion can apparently relieve the painful and swelling degree of obsolete collateral ligament injury of interphalangeal joints, which is superior to TDP.</p>
