Dr. Robert Topp at Marquette University has published several studies on the mechanisms of Biofreeze® topical analgesic, as well as exercise interventions using Thera-Band resistance in knee osteoarthritis patients. At TRAC 2011, Dr. Topp presented research on the efficacy of Biofreeze in 20 patients with knee osteoarthritis. The patients had either Biofreeze or a placebo gel applied to their knee; each then performed 5 functional tasks and subsequently reported their pain levels.
The subjects performed significantly better on the 6-minute walk and timed chair-stand when Biofreeze was applied. Applying Biofreeze also significantly reduced pain during the timed chair stand, timed up-and-go, as well as going up and down stairs.
Dr. Topp concluded that Biofreeze topical analgesic resulted in 30% less pain than a placebo during high-load functional tests in patients with knee osteoarthritis.
