Shortwave Diathermy Increases Blood Flow and Skin Temperature in Lower Limbs
Full Title
Application of Shortwave Diathermy to Lower Limb Increases Arterial Blood Flow Velocity and Skin Temperature in Women: A Randomized Controlled Trial
Summary
This randomized controlled trial examined the effects of shortwave diathermy (SWD) and microwave diathermy (MWD) on blood flow and skin temperature in the lower limbs of healthy women. Forty participants received 20 minutes of either SWD or MWD to the posterior thigh and leg. Measurements taken before, immediately after, and at 10 and 20 minutes post-treatment showed that SWD significantly increased arterial blood flow velocity and sustained skin temperature elevation for at least 20 minutes. MWD also increased skin temperature but had no significant effect on blood flow. These findings highlight SWDâs potential for improving circulation and tissue heating.
