Pulsed Radiofrequency Therapy for Hand OsteoArthritis Pain
- Conditions
- Hand Osteoarthritis
- Interventions
- Device: ShamDevice: Transcutaneous pulsed radiofrequency
- Registration Number
- NCT05217979
- Lead Sponsor
- Leiden University Medical Center
- Brief Summary
Different types of pain may be present in patients with hand osteoarthritis, including nociceptive pain and non-nociceptive pain. This makes adequate pain treatment difficult, and thus new treatment options are needed. To this end, this trial will evaluate the effect of transcutaneous pulsed radiofrequency for the treatment of hand osteoarthritis pain.
- Detailed Description
In this randomized clinical trial, patients with hand osteoarthritis, recruited from the Leiden University Medical Center Rheumatology outpatient clinic, aged 18-80 and fulfilling hand pain criteria will be randomized to undergo trancutaneous pulsed radiofrequency therapy of the hand or a sham. The effect will be measured in change in 10 point numeric rating scale for pain in the hand over 6 weeks. This RCT will have little burdens and risk for the subjects. The proposed intervention, tPRF, is well tolerated, with no known serious side effects.

- Arm && Interventions
Group Intervention Description Sham Sham After signing informed consent, patients assigned to the sham group by randomization will receive a single treatment with sham, which is indistinguishable from the active treatment. This is achieved by putting the device in demo mode, which gives all the same audiovisual signals as the active mode, but no treatment. Given that the treatment is not felt by patients, this ensures blinding. Transcutaneous pulsed radiofrequency Transcutaneous pulsed radiofrequency After signing informed consent, patients assigned to the intervention group by randomization will receive a single treatment with transcutaneous pulsed radiofrequency.
- Primary Outcome Measures
Name Time Method Hand pain at 6 weeks after trancutaneous pulsed radiofrequency or sham 6 weeks Hand pain measured in a 0-10 numeric rating scale after trancutaneous pulsed radiofrequency or sham
- Secondary Outcome Measures
Name Time Method Hand pain at 12 weeks after trancutaneous pulsed radiofrequency or sham 12 weeks Hand pain measured in a 0-10 numeric rating scale after trancutaneous pulsed radiofrequency or sham
Efficacy of transcutaneous pulsed radiofrequency on hand function 6 weeks, 12 weeks Efficacy of trancutaneous pulsed radiofrequency on hand function (Australian/Canadian Hand Osteoarthritis Index \[AUSCAN\] function subscale, range 0-36, with higher scores indicating lower function)
Efficacy of transcutaneous pulsed radiofrequency on hand stiffness 6 weeks, 12 weeks Efficacy of trancutaneous pulsed radiofrequency on hand stiffness (Australian/Canadian Hand Osteoarthritis Index \[AUSCAN\] stiffness subscale, range 0-4, with higher scores indicating more stiffness)
Global perceived effect of recovery due to trancutaneous pulsed radiofrequency 6 weeks, 12 weeks Global perceived effect of recovery due to trancutaneous pulsed radiofrequency, range 0-7, with lower scores indicating better outcomes, reported by patients with hand osteoarthritis
Efficacy of transcutaneous pulsed radiofrequency on the number of tender joints 6 weeks, 12 weeks Efficacy of trancutaneous pulsed radiofrequency on the number of tender joints (Tender joint count)
Efficacy of trancutaneous pulsed radiofrequency on anxiety 6 weeks, 12 weeks Efficacy of trancutaneous pulsed radiofrequency on anxiety measured with the Hospital Anxiety and Depression Scale, anxiety subscale, range 0-21, with higher scores indicating higher likeliness of anxiety, in patients with hand osteoarthritis
Efficacy of trancutaneous pulsed radiofrequency on depression 6 weeks, 12 weeks Efficacy of trancutaneous pulsed radiofrequency on depression measured with the Hospital Anxiety and Depression Scale, depression subscale, range 0-21, with higher scores indicating higher likeliness of depression, in patients with hand osteoarthritis
Global perceived effect of satisfaction with trancutaneous pulsed radiofrequency 6 weeks, 12 weeks Global perceived effect of satisfaction with trancutaneous pulsed radiofrequency, range 0-7, with lower scores indicating better outcomes, reported by patients with hand osteoarthritis
Effect of transcutaneous pulsed radiofrequency therapy on health related quality of life 6 weeks, 12 weeks Effect of transcutaneous pulsed radiofrequency therapy on health related quality of life measured with Short Form-36. Scores are standardized with a mean of 50 and sd of 10, with higher scores indicating better outcomes
Effect of transcutaneous pulsed radiofrequency therapy on temporal summation assessed using a 256 mN PinPrick 6 weeks Effect of transcutaneous pulsed radiofrequency therapy on abnormalities measured with temporal summation, scored as present or absent. Patients will receive a single stimulation with the pinprick, scored 0-10 on NRS pain, followed by 10 stimuli with the pinprick, of which the last stimulus is scores 0-10 on NRS pain. This is repeated 5 times. The single stimuli are averaged, as are the 10th stimuli, and the ratio between these averages is calculated. A ratio \>2 is indicative of temporal summation.
Effect of transcutaneous pulsed radiofrequency therapy on numbness of the hand. 6 weeks Effect of transcutaneous pulsed radiofrequency therapy on numbness scored as present or absent, based on 5 stimuli with the PinPrick. Any stimulus rated as numb is regarded abnormal.
Effect of transcutaneous pulsed radiofrequency therapy on allodynia 6 weeks Effect of transcutaneous pulsed radiofrequency therapy on allodynia, scored as present or absent. Scoring based on stimuli with a standardized brush, which is used to apply 5 stimuli to the back of the hand. Any of the stimuli evoking pain (score of \>0 on a 0-10 NRS) is regarded as abnormal.
Effect of transcutaneous pulsed radiofrequency therapy on Michigan Hand Outcome Questionnaire 6 weeks, 12 weeks Effect of transcutaneous pulsed radiofrequency therapy on MHOQ scores, ranged 0-100 per domain, with higher scores indicating better oucomes.
Effect of transcutaneous pulsed radiofrequency therapy on central sensitization index scores 6 weeks, 12 weeks Effect of transcutaneous pulsed radiofrequency therapy on central sensitization index scores, range 0-100, with higher scores indicating more signs of central sensitization.
Effect of transcutaneous pulsed radiofrequency therapy on PainDETECT scores 6 weeks, 12 weeks Effect of transcutaneous pulsed radiofrequency therapy on PainDETECT scores (range -1 to 38, with scores \<13 indicating presence of neuropathic pain is unlikely, scores 13-18 indicating presence of neuropathic pain is undetermined and scores \>18 indicating neuropathic pain presence is likely).
