Aim: A randomised single-blind placebo study was conducted on 80 patients with pedal diabetic peripheral neuropathy in 2 cities and their surrounds in South Africa to determine if a pulsed radio frequency current (PRF) can produce changes in the primary outcome of the DN4 Test and possibly in the BPI-short form.
Conclusion: After 3 treatments of PRF current, the DN4 Test demonstrates significant improvements in neuropathic pain and symptoms in certain patients with diabetic peripheral neuropathy.
