Gold Coast, Australia (January 2020): The results of a Griffith University randomized, placebo-controlled, double-blind clinical trial of PSE were published today, confirming the efficacy and remarkable results of PSE in a cohort of stroke survivors with relentless, intractable daily pain after stroke. The individuals were treated an average of about 4 years after stroke and each reported constant daily pain after their stroke that had failed to adequately respond to all previous forms of treatment. They received two doses of PSE, each two weeks apart, with the control group receiving two doses of saline administered perispinally. The control group had no change in their daily pain, but the treatment group had a significant reduction in pain, measured at 30 days, with 30% of the treatment patients showing near complete pain abatement after the first PSE treatment. The study concludes: “PSE can provide significant and ongoing benefits for the chronic post-stroke management of pain and greater shoulder flexion by the paretic arm. Effects are rapid and highly significant, supporting direct action on brain function.” The PSE stroke treatment was invented by Edward Tobinick, M.D., Director of the Institute of Neurological Recovery in Boca Raton, Florida. Dr. Tobinick was instrumental in the design of the University clinical trial.
Lead investigator Associate Professor Stephen Ralph from Griffith’s School of Medical Science said the findings from the peer-reviewed, double-blinded, placebo controlled, randomized clinical trial were unprecedented in terms of beneficial improvements that were provided in recovery of participants from stroke-related disability and a ‘game-changer’ for medicine.
“These findings support the published observations from animal models of stroke, prior case studies and open-label/observational studies on over a thousand stroke patients reported previously,” he said.
The results have been published in the journal Expert Opinion on Investigational Drugs.
A detailed analysis of the clinical trials results and scientific/medical significance have been published on February 6, 2020 in the journal Expert Review of NeurotherapeuticsF
