Sham Comparator
Therapeutic ultrasound combine TENS
Therapeutic ultrasound with sham TENS
Use therapeutic ultrasound with simultaneous TENS for 10 minutes/session for 10 sessions/course. The therapeutic ultrasound machine in this study was Sonopuls 492 TM (Enraf-Nonius), this device has treatment head described by the manufacturers as having surface area as 5.8 cm2, ERA (Effective Radiating Area) of 5.0 cm2 and BNR (Beam Non-uniform Ratio) as max. 5.0. For electrotherapy unit which composes of 2 channels, output characteristics are constant current (CC) or constant voltage (CV), resolution of output signal is in steps of 0.2 mA and timer is limited to 30 minutes during ultrasound and combination therapy are operated.
Use the same therapeutic ultrasound machine and place the electrode as experimental group but turn-off electrical current during treatment period
