• Thermal - hyperemia , increase alkalosis, increased leukocytosis, increased glandular activity, reduce muscle spasm and deep heating
• Mechanical – dispersion of fluids, removes exudates, increased molecular movement and increase membrane permeability.
• Chemical - increase gaseous exchange and increase chemical oxidation aids in healing
• Neural – mild anesthesia
• Joint and musculoskeletal inflammation
• Subacute sprains, strains, contusions, tendinitis, bursitis
