Phonophoresis

Phonophoresis is a process in which whole medicinal molecules are driven across the skin and into the subcutaneous tissue by means of ultrasound

• 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

• Medications is spreed over a larger area
• Noninvasive
• Medication bypasses the liver, lessening metabolic elimination

• most common usesare for subcutaneous inflammatory and painful conditions using anesthetics or nonsteroidal or steroidal antiinflammatory drugs
• Hydrocortisone
• Dexamethasone

• same as ultrasound
• any contraindicatios for the durg being used

• 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

• Thermal effects of ultrasound increases the local cells and medications kinetic energy
• Dilate the point of entry
• Increase circulation
• Increases capillary permeability

• altering the cells resting potential
• affecting the permeability of ionized and unionized molecules
• increasing cell membrane permeability

• 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
