The objective of the study was to determine the effect of short-wave diathermy on joint mobility and radiographic changes during the development of osteoarthritis. An experimental model for osteoarthritis was developed by periodic immobilization of rabbit knees. Nine rabbits was given short wave diathermy in the same knee 55 times for 5 minutes with a power of 50 W for 11 weeks. An identically immobilized group of 17 rabbits was used as control. The most significant effect on the mobility of the treated knee was the development of extension deficiency. This limitation developed within a week and was permanent. A smaller effect was found on flexion mobility. Flexion deficiency decreased at the end of the immobilization period and increased during remobilization, though at the end of the experiment there were no differences compared with the control. Radiographic changes were similar during the development of osteoarthritis in treated and non-treated groups.
本研究的目的是确定短波透热疗法对骨关节炎发展过程中关节活动度和影像学变化的影响。通过周期性固定兔膝关节建立骨关节炎实验模型。9只兔子的同一膝关节接受50瓦功率的短波透热疗法，每次5分钟，共55次，持续11周。将17只同样固定的兔子作为对照组。对治疗膝关节活动度最显著的影响是伸直受限的出现。这种限制在一周内出现且是永久性的。在屈曲活动度方面发现的影响较小。固定期结束时屈曲受限程度降低，重新活动期间增加，不过在实验结束时与对照组相比没有差异。治疗组和未治疗组在骨关节炎发展过程中的影像学变化相似。
