Its analgesic effect lies in the stimulation of A and C fibers by cold and nociceptive stimulation, respectively, which is produced by menthol, apparently through the newly discovered receptor TRPM8 (Transient Receptor Potential melastatin-8) The aim of this study is to investigate if BIOFREEZE ® treatment (Performance Health Inc., Export, PA) improves symptoms associated with moderate knee osteoarthritis, which would decrease the immobility and isolation in older adults.","overall_status":"Withdrawn","phases":["PHASE3"],"study_type":"INTERVENTIONAL","sponsor":"University of Chile","enrollment":0,"countries":["Chile"],"start_date":"2012-04-01","completion_date":"2012-12-01","last_update_date":"2014-07-10","source_url":"https://clinicaltrials.gov/study/NCT01565070","editorial_summary":"A registered PHASE3 study indexed because it matched monitored longevity research terms.
