Interventions
For the TCPRF acupuncture group, the investigators choose ST34 (Liangqiu), SP10 (Xuehai), GB34 (Yanglingquan), SP9 (Yinlingquan) around the affected knee. The TCPRF device is a wearable modality with innovative pulse radiofrequency technology aimed at alleviating symptomatic chronic pain, which revealed that UHF (500-kHz sine wave, 2-Hz frequency with a 25-ms pulse). It was attached to the electrode pad through magnetic attraction. A 500-KHz stimulus was delivered. The symmetric two-phase sine wave has a 2-Hz frequency witha 25-ms pulse width. The treatment has 15 min per time. Electrical stimulation is administered for 30 minutes each session, divided into two 15-minute phases. After the first 15 minutes, the treatment is paused and then restarted for an additional 15 minutes. The output peak current was 13.2 mA and the output peak voltage was 6.6 V at 500 Ω.
same protocol will be done on the same acupoints, but the machine will be turn off interiorly. Therefore, although the machine still has lights and a vibrating sensation, it will not release PRF waves.
