I would have to disagree with the comment that dosimitry is supported by clinical evidence, it is definately not. There is no evidence to prove dosimitry parameters although there is some laboratory evidence to show that there may be some physiological changes associated with SWD. As observed above there is almost very little use of PSWD with even less use of SWD. If in doubt use athermal doses until you are sure of no adverse effects and ensure you check contraindications to treatment with PSWD/SWD.
