Summary

It is a double-blind randomized sham-controlled clinical trial to evaluate the effectiveness of resistive capacitive diathermy in subjects affected by knee osteoarthritis in comparison with a "sham" diathermy treatment. The resistive capacitive diathermy is a medical device supplying low (448 KHz) radiofrequencies with maximum output power of 200 W, used to reduce pain and inflammation and allowing healing processes. The sham diathermy treatment is administered with the device set on "on" but not active (not supplying energy). Each subject, randomly assigned to either resistive capacitive diathermy treatment (group 1) or sham-treatment (group 2) is submitted to a thirty minutes session, three times per week for a total of ten sessions. The outcome measures are the WOMAC scale (Western Ontario and McMaster Universities Arthritis Index) to assess pain and physical functioning, a visual analogic scale (VAS) for pain, the femoral quadriceps strength (MRC = Medical Research Council Scale). Outcome measures are administered at baseline (T0), at the end of the treatment protocol (T1), at 1 month (T2) and 3 months (T3) after the end of treatment.

Interventions

Type	Name	Description
DEVICE	resistive capacitive diathermy treatment (resistive capacitive diathermy, Hcr 902, Unibell)	The resistive capacitive diathermy is a medical device supplying low (448 KHz) radiofrequencies with maximum output power of 200 W. It is used to reduce pain and inflammation and allowing healing processes. diathermy treatment is administered for a thirty minutes session, three times per week for a total of ten sessions.
OTHER	sham placebo resistive capacitive diathermy treatment	The sham treatment is administered with the diathermy device set on "on" but not active (not supplying energy) and the treatment session has the same modalities, frequency and duration of experimental diathermy group
