Outcome Measures

Primary Outcomes (1)

  • Western Ontario and McMaster Universities Osteoarthritis Index

    WOMAC is used to assess pain(5 items), stiffness(2 items), and physical function(17 items) of knee OA with excellent validity and reliability. Higher scores mean worse symptoms with more functional limitation.

    From enrollment to the end of treatment at 4 weeks

Secondary Outcomes (6)

  • Western Ontario and McMaster Universities Osteoarthritis Index

    12 weeks after completing treatment

  • visual analogue scale

    From enrollment to the end of treatment at 4 weeks and 12 weeks after completing treatment

  • Tampa Scale for Kinesiophobia

    From enrollment to the end of treatment at 4 weeks and 12 weeks after completing treatment

  • World Health Organization Quality of Life-Brief Version

    From enrollment to the end of treatment at 4 weeks and 12 weeks after completing treatment

  • Biodex Stability System

    From enrollment to the end of treatment at 4 weeks and 12 weeks after completing treatment

  • +1 more secondary outcomes

Study Arms (2)

TCPRF acupuncture group

EXPERIMENTAL

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. treatment 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.

For the TCPRF acupuncture group, the investigators choose ST34 (Liangqiu), SP10 (Xuehai), GB34 (Yanglingquan), SP9 (Yinlingquan) around the affected knee.

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.

Eligibility Criteria

Age45 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age from 45 to 85 year-old with knee pain for more than six months
  • Fulfill the combined clinical and radiographic criteria of knee OA established by the American College of Rheumatology with a Kellgren and Lawrence score of 2 or greater
  • Pain score above 3 (range 0-10 on the visual analog scale; higher scores indicate greater pain
  • Could participate in 4 weeks of treatment and 3 months of follow-up

You may not qualify if:

  • Knee OA combined with any infection, inflammation, autoimmune disease, or fracture
  • History or underlying disease that would affect posture and balance, such as malignancy, dizziness, vertigo, or stroke
  • Ever underwent any type of knee operation or internal fixation
  • Pregnant or planning to become pregnant
  • Receiving other treatment for knee OA in previous 3 months
  • History of epilepsy, electronic devices implanted in the body
  • Active infection at the stimulator contact site
  • Lack of informed consent
  • Any other reason thought likely to result in inability to complete the trial
