A Survey of the Effects of Electrical Stimulation on Pain in Patients with Knee Osteoarthritis

Objective: To determine whether electrical stimulation therapy is effective at reducing pain in people with knee osteoarthritis. Methods: Various literatures on the treatment of pain in osteoarthritis of knee joint with electrical stimulation were searched. According to the title and abstract, the search records were independently screened, and the author, study design, study population, type of electrical stimulation, evaluation criteria, results and other information were extracted. Results: Ten randomized controlled trials involving 405 patients diagnosed with knee osteoarthritis found that both TENS and NMES had a positive effect on the analgesic effects of knee arthritis, but further work is still needed to clarify the long-term treatment effect of electrical stimulation in terms of knee arthritis pain. Conclusion: TENS treatment is more effective than NMES treatment in relieving joint pain in people who have KOA. In future studies, In future studies, the experimental analysis of the same parameter of TENS is needed to determine better methods of pain relief.
