各种物理因子有无特异性作用,是理疗学的重要的基本理论问题。五十年代以前,不少国家的理疗工作者认为某些物理因子的治疗作用基本相同,而对其特异性作用则缺乏足够重视。近三十年来,由于科学技术的迅速发展,对物理因子的原发性作用机制、作用效果和后作用有了进一步的了解。物理因子具有特异性作用已基本上得到公认,需要研究的是不同条件对其影响及其表现程度问 Whether or not the various physical factors have a specific role is an important basic theoretical issue in physiotherapy. Before the 1950s, physiotherapists in many countries considered that the therapeutic effects of some of the physical factors were basically the same, while their specific roles were not sufficiently taken seriously. In the recent three decades, due to the rapid development of science and technology, the primary mechanism, effect and post-action of physical factors have been further studied. Physical factors have a specific role has been basically recognized, need to be studied is the impact of different conditions and their performance level asked
