We examined the effects of acupuncture therapy on 41 patients with various levels of periarthritis scapulohumeralis. These patients were classified into two groups: one consisting of 20 patients having no contracture, those of freezing type (age 61.0±9.0; suffering period 3.0±5.1 months) and the other consisting of 21 patients having contracture, those of frozen type (age 53.8±7.3; suffering period 5.8±7.8 months).
As a result, we found that acupuncture therapy relieved pain more effectively in patients having no spontaneous pain than in those having spontaneous pain regardless of the presence or absence of contracture. We next investigated the effects of this therapy by the patient types. In the group of 20 freezing-type patients, which includes only six patients having spontaneous pain, pain relief was relatively easily obtained as indicated by the pain score after the therapy of 3.6±1.8. In the group of 21 frozen-type patients, which includes 13 patients having spontaneous pain, however, it was difficult to obtain sufficient pain relief as indicated by the pain score of 5.7±2.8. There was a statistically significant difference (P<0.002) between these scores. This shows that acupuncture therapy is more effective on freezing-type patients than on frozen-type patients.
Therapy also improved the range of motion. In many freezing-type patients, the range of motion was expanded due to pain relief. The abduction ROM expanded from 151.8±39.0° before therapy to 163.8±25.0° after acupuncture therapy. In frozen-type patients, however, the range of motion did not expanded significantly (87.6±24.1° before to 94.8±21.1° after therapy). The above results suggest that acupuncture therapy is effective for relieving the pain of periarthritis scapulohumeralis and that this therapy is particularly effective when applied to those patients having no spontaneous pain before they enter into the frozen phase.
