AIM: To observe the therapeutic effects of dumbbell gymnastics and bare-handed exercise in ameliorating the symptoms of shoulder periarthritis. METHODS: Fifty-four patients with shoulder periarthritis from the Taigang Group Linfen Iron and Steel Company took part in the study voluntarily between March and May 2004. They all accorded with the standard of shoulder periarthritis diagnostics in "clinical pain therapy", and then they were randomly divided into dumbbell gymnastics group (n = 26) and bare-handed exercise group (n = 28). Patients in the dumbbell gymnastics group exercised 2 to 3 times per day and 5 to 10 minutes for each time, the dumbbell weighed about 2 to 5 kg. After 3 months, the amelioration of the symptoms and the changed range of the indexes of shoulder's joint activity were compared in the two groups, the evaluation standards were that excellent: the pain disappear and the function recover normal completely. Good, a little pain when action, also the function recover normal party. General: Both the pain and the press ache are relieving and the limit of joint is improved. Bad: the pain is almost patently improved as well as the press ache, including the limit of joint. The t test and Chi-square test were used. RESULTS: According to intention-to-treat analysis, all the 54 patients were involved in the analysis of results. (1) After 3-month exercise, the effect was excellent in 24 cases and good in 2 cases of the dumbbell gymnastics group (effective rate: 86.7%, excellent rate: 92.3%), it was general in 16 cases and bad in 7 cases of the bare-handed exercise group (effective rate: 48.6%, excellent rate: 17.8%), the effect was significantly different between the two groups (Chi2 = 5.69, p < 0.05). (2) The average exercise times were fewer in the dumbbell gymnastics group than in the bare-handed exercise group (13.1 +/- 2.1, 19.3 +/- 3.2 times, t = 2.805, p < 0.05). (3) The changed ranges were significantly higher in the dumbbell gymnastics group than in the bare-handed exercise group (92.46 +/- 17.14 degrees, 85.41 +/- 13.34 degrees; 31.42 +/- 15.21 degrees, 29.96 +/- 8.63 degrees; 96.63 +/- 29.49, 89.81 +/- 20.53 degrees, p < 0.05). CONCLUSION: Dumbbell gymnastics exercise has a better effect than bare-handed exercise both in the intensity aspect and curative effect aspect.
