Abstract
Background
Idiopathic lower extremity edema, characterized by recurrent swelling without an identifiable underlying disease or medication-related cause, is associated with altered fluid distribution and peripheral circulation. Radiofrequency diathermy (RFD) may influence local thermal and circulatory conditions; however, its short-term effects on edema-related parameters remain unclear. This study aimed to evaluate the short-term changes in lower extremity volume and related physiological measures following RFD in women with idiopathic lower extremity edema.
Methods
A randomized, assessor-blinded, sham-controlled crossover study was conducted in 14 women with idiopathic lower extremity edema. Participants received both active RFD and sham treatments once daily for three consecutive sessions, with the two treatment periods separated by a 4-week washout period. Leg volume, circumference, body weight, pain intensity, and skin temperature were measured before and after each session.
