Transcutaneous Pulsed Radiofrequency Treatment in Patients with Osteoarthritis of the Upper Extremity

Background: Non-invasive treatment options are preferred for managing upper extremity pain due to osteoarthritis (OA). Transcutaneous pulsed radiofrequency (TcPRF) is a promising technique and appears effective in managing knee and shoulder pain. Objectives: To investigate whether TcPRF treatment is effective in reducing pain and safe to use among patients with OA of the upper extremity. Methods: In this retrospective study, patients with painful OA of the upper extremity who underwent TcPRF treatment from February 2021 to February 2022 were included. The primary outcome measure was the change in NRS pain scores between baseline and 1, 2, and 6 weeks of follow-up. Secondary outcome measures included adverse events. Data were extracted from electronic medical records and via telephone consultation after the 6-week follow-up. Results: A total of 41 initial TcPRF treatments were performed among 37 patients. The NRS score at rest showed a statistically significant improvement at 6 weeks [median = 5 [interquartile range (IQR) 2 - 8)] compared with baseline [median = 6 (IQR 4 - 8)], P = 0.023, with a moderate effect size, r = -0.44. For NRS scores during activity, all follow-up moments had lower NRS scores [median = 7 (IQR 5 - 8)] than before TcPRF [median = 8 (IQR 7 - 9)], P = 0.002 - 0.006, with moderate to large effect sizes, r = -0.45 to r = -0.51. No adverse events were reported. Conclusions: Transcutaneous pulsed radiofrequency treatment is effective in reducing pain and is safe to use among patients with upper extremity pain due to OA.

Two Transcutaneous Stimulation Techniques in Shoulder Pain: Transcutaneous Pulsed Radiofrequency (TPRF) versus Transcutaneous Electrical Nerve Stimulation (TENS): A Comparative Pilot Study.

Objective To compare the safety and efficacy of 2 transcutaneous stimulation techniques, transcutaneous pulsed radiofrequency (TPRF) versus transcutaneous electrical nerve stimulation (TENS), in chronic shoulder tendonitis. Design A prospective, randomized, and double-blind clinical trial. Setting Academic pain service of a city hospital. Subjects Fifty patients with sonography-confirmed shoulder tendonitis. Methods Fifty patients were randomly allocated into two groups for electrical stimulation treatment with 3-month follow-ups: Group 1 (n=25), TENS and Group 2 (n=25), TPRF. Both groups underwent either treatment for 15 minutes every other day, three times total. Our primary goals were to find any treatment comfort level, adverse event, and changes in Constant–Murley shoulder (CMS) scores. The secondary goals were finding the changes in pain, enjoyment of life, and general activity (PEG) scores. Results For primary goals, no adverse events were noted throughout this study. No differences were found between groups for treatment tolerability (3.20 + 0.87 vs. 2.16 + 0.75). Statistically significant lower PEG scores were noticeable with the TPRF group after the course (12.73 + 5.79 vs. 24.53 + 10.21, p=0.013). Their statistical significance lasted for 3 months although the difference gap diminished after 1 month. CMS scores were significantly higher in the TPRF group (70.84 + 6.74 vs. 59.56 + 9.49, p=0.007) right after treatment course but the significance did not last. Conclusions In treating chronic shoulder tendinitis using two transcutaneous stimulation techniques, both TPRF and TENS are safe and effective. TPRF is superior to TENS.

Transcutaneous Pulsed Radiofrequency Treatment for Patients with Shoulder Pain Booked for Surgery: A Double‐Blind, Randomized Controlled Trial

Shoulder pain is the third most common musculoskeletal problem and accounts for 5% of general practitioner consultations. Although many treatments are described, there is no consensus on optimal treatment and up to 40% of patients still have pain 12 months after initially seeking help for pain. Previously, the effect of transcutaneous pulsed radiofrequency treatment (TCPRFT) was evaluated in a retrospective audit that showed good pain relief for a mean 395 days and justified this randomized sham controlled trial. In this study, 51 patients entered into a randomized double-blinded, placebo controlled study of TCPRFT. Patients were assessed at 4 and 12 weeks by a blinded observer and compared with baseline. We observed sustained reductions in pain at night, pain with activity, and functional improvement at 4 and 12 weeks with active but not sham TCPRFT. The 25 subjects who received active treatment showed statistically significant reductions of 24/100 in pain at night and 20/100 of pain with activity at 4 weeks and 18/100 and 19/100, respectively, at 12 weeks from baseline. Statistically significant lower Brief Pain Inventory pain and function scores (4 and 12 weeks), improved pain self-efficacy (4 weeks), Oxford Shoulder scores (12 weeks), and internal rotation (12 weeks) were seen. Pain at both rest and shoulder elevation were not improved by active treatment. No complications were seen. This study of a simple, low risk, outpatient treatment confirms the findings of our earlier study of TCPRFT for knee pain and shoulder pain audit that transcutaneous pulsed radiofrequency treatment may help some people with painful shoulders.

Transcutaneous Application of Pulsed Radiofrequency Treatment for Shoulder Pain

We report a retrospective audit of transcutaneous pulsed radiofrequency treatment therapy (TCPRFT) for shoulder pain over a 4-year period. Electronic and manual case review revealed that TCPRFT had been performed on 13 patients, with 15 painful shoulders, using a single treatment session between 2006 and 2010 in an outpatient setting. Of the 15 shoulders treated, 10 (two-thirds) had pain relief for over 3 months with an average pain score reduction of 6.1 of 10 and an average duration of pain relief of 395 days. Two experienced pain relief of < 3 months with an average reduction in pain score of 4.3 of 10 and an average duration of effect of 11 days. Three cases experienced no pain relief from the treatment. These results suggest TCPRFT may provide clinically useful pain relief and be another treatment modality for shoulder pain. Our findings justifies further research, and we are proceeding with a double-blind placebo randomized controlled studies to determine the efficacy of TCPRFT in chronic shoulder pain.

Transcutaneous Pulsed Radiofrequency Treatment in Patients With Painful Knee Awaiting Total Knee Joint Replacement

Our study was designed to determine if transcutaneous-pulsed radiofrequency treatment (TCPRFT) was able to reduce the pain experienced by patients awaiting total knee joint replacement (TKJR). We conducted a randomized, double-blinded, placebo controlled trial of TCPRFT in patients referred for TKJR to our hospital's Orthopedic Outpatient Clinic. Patients on the waiting list for assessment for TKJR were invited to participate and were examined in the clinic if they satisfied the inclusion criteria. Patients were randomized to receive active or sham TCPRFT. The alteration in pain and function of the treated knee after a single TCPRFT was assessed at examination at 1 and 4 weeks using visual analog pain score (VAS) at rest and after 20 and 400 m walks. The results of 50 patients showed a statistically significant reduction in VAS at 1 and 4 weeks compared with baseline in the group who received active treatment. We also demonstrated what is considered a clinically significant improvement in this group that became more pronounced at week 4 compared with week 1 and also more after a 400 m walk compared with a 20 m walk. Maximum improvement observed in group data was 19/100 VAS. Patients receiving sham treatment showed no statistically significant improvement. We believe this to be the first report of a controlled study of TCPRFT. This pilot study shows a benefit of the technique that justifies future research.
