1. Define Phonophoresis
    Phonophoresis is a process in which whole medicinal molecules are driven across the skin and into the subcutaneous tissue by means of ultrasound
  2. The Purpose and Effects of Phonophoresis
    • Introduces medication to a local area
    • Painless and safer that injections
    • Uses Diffusion
    • Ultrasound opens pathways tat allow the medication to diffuse through the skin and pass into deeper tissue
  3. Advantages of Phonophoresis
    • Medications is spreed over a larger area
    • Noninvasive
    • Medication bypasses the liver, lessening metabolic elimination
  4. Indication for Phonophoresis
    • most common usesare for subcutaneous inflammatory and painful conditions using anesthetics or nonsteroidal or steroidal antiinflammatory drugs
    • Hydrocortisone
    • Dexamethasone
  5. Contraindications and Precautions
    • same as ultrasound
    • any contraindicatios for the durg being used
  6. Rate of absorption for Phonophoresis
    • All medications have to go threw epidermis and stratum cornuem before it reasches the subcutaneous tissues
    • layer of skin determines the rate and amount of medications tat is transmitted to the deeper tissue
    • The type and consistency of the skin overlying the treatment area are the most important elements in determining the success of the treatment
  7. Thermal Effects of Phonophoresis
    • Thermal effects of ultrasound increases the local cells and medications kinetic energy
    • Dilate the point of entry
    • Increase circulation
    • Increases capillary permeability
  8. Nonthermal Effects of Phonophoresis
    • altering the cells resting potential
    • affecting the permeability of ionized and unionized molecules
    • increasing cell membrane permeability
  9. Dosage of Phonophoresis
    • Intesity : low intensity is better to deliever the medication
    • Duration : 5-10 mins to reach therapeutic temp at 1.0-1.5 w/cm
    • Frequency: consultation with MD
