Pulsed electromagnetic fields can reduce pain in the short term in patients with knee osteoarthritis [commentary]

摘要

SummarySummary scores (0 to 100). Results: A total of 60 participants (91%) completed the assessment at 1 month. The mean difference was 13.6 units (95% CI 7.9 to 19.3) in VAS-pain and 5.6 units (95% CI 2.9 to 8.4) in WOMAC-pain, both favouring the active pulsed electromagnetic fields group. There were minor differences in favour of the pulsed electromagnetic fields group in the SF-36 physical health (mean difference 2.7 units, 95% CI 0.3 to 5.2) and the SF-36 mental health (mean difference 0.5 units, 95% CI C1.5 to 2.6). Conclusion: In patients with painful knee osteoarthritis, pulsed electromagnetic fields decreased pain, but had little impact on health-related quality of life. Provenance: Invited.
