  Purpose

Biofreeze® is a topical ointment that has menthol and alcamphor. 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.

Primary Outcome Measures:
  • WOMAC score [ Time Frame: 60 days ] [ Designated as safety issue: No ]
    WOMAC score corresponds to Western Ontario and McMaster Universities Index of Osteoarthritis


Secondary Outcome Measures:
  • Quality of life measured using SF 36 [ Time Frame: 60 days ] [ Designated as safety issue: No ]
    SF 36 correponds to a health related quality of life score
