Post# of 8680

Sixty-one participants were recruited, and 51 participants completed the study at 4 weeks. Both the PEMF therapy and sham device groups showed improvements in average NPRS and PRWHE at 4 weeks, but there was not a significant improvement between groups. At 6 weeks, there was a significantly greater change in average NPRS from baseline in the PEMF therapy group compared with the sham device group (P = .02).
Conclusions:
Pulsed electromagnetic field therapy may improve thumb CMC OA pain with sustained relief beyond the treatment period. Future studies will need to assess if adjusting treatment duration or other factors can enhance its efficacy.
