PHONOPHORESIS

WHAT IS PHONOPHORESIS

Phonophoresis is the process of introducing substances into the body by using ultrasonic energy.

This procedure is improperly compared with iontophoresis which involves transfer of ions into the body tissues while phonophoresis involves transmit of molecules into the body tissue by using different procedure, although is based on a similar concept.

these molecules introduced into the body target tissue must be broken into component elements and radicals by using natural processes and recombined with existing bloodstream radicals.

    METHOD USED FOR PHONOPHORESIS

The technique or method used for phonophoresis is the same method as that for standard ultrasound administration.

solutions are not used for phonophoresis, It is physical therapeutic procedure that combines ultrasound and medications, where the medicinal substance are applied directly to the skin and ultrasonic energy is applied by using ultrasound machine, this ultrasonic energy will help the skin to absorb the substance into the subcutaneous tissues.

MOLECULAR SUBSTANCES INTRODUCED INTO THE BODY BY PHONOPHORESIS

(1) Hydrocortisone

  • used as anti-inflammatory agent and also analgesic 
  • as 1% ointment and some practitioner refer it as 10%
(2) Mecholyl
  • suitable base for either iontophoresis or phonophoresis as 10%
  • It is an effective vasodilator
  • as 5% ointment
  • used primarily as analgesic and anaesthetic in acute conditions
  • used as vasodilating agent and anti-inflammatory agent in cases like scar tissue, adhesions and adhesive joint and calcific deposits.
  • It is basic anti-inflammatory agent and also used as decongestant and as chemically related aspirin.
  • used for the treatment of open wounds and lesions.

(3) Lidocaine

(4) Iodine

(5) Salicylate

(6) Zinc 

INDICATIONS OF PHONOPHORESIS

(1) Tendinitis

(2) Bursitis

(3) Sprain and strain

(4) Pain 

(5) Inflammatory conditions

CONTRAINDICATIONS OF PHONOPHORESIS

(1) Patients who are sensitive to aspirin with salicylates are not treat with phonophoresis

(2) Do not treat patients who have reaction mecholyl with vasomotor shifting 

(3) Patients who are sensitive to metals should not be treated with zinc

(4) Patients who cannot eat sea food should not be treated with iodine and if there is any report of skin irritation and itching.

PRECAUTIONS OF PHONOPHORESIS

(1) Check the patient for sensitivity or allergies to the substance used

(2) Maintain uniform contact between the ultrasound head and the area treated, if not burns may occur

(3) Do not treat over bony prominences to eliminate possibility of concentrated energy causing localized heating 

(4) Do not treat over or near the heart

(5) When the unit (machine) is on, do not hold the ultrasound head in the air or break treatment contact, as this could damage the ultrasound head crystal.

(6) Complaint of sharp pain by the patient indicates that the intensity needs to be reduced and more coupling medium needs to be added

(7) Keep the ultrasound head moving continuously on the skin throughout the treatment time, if not burns may occur by overheating of the tissue.

HYDROTHERAPY

WHAT IS HYDROTHERAPY Hydrotherapy is also known as water therapy which in medical term implies using water for therapeutic purpose or simply treatment by water in which water is used as a medium for exercise and provides several opportunities, which are not available in exercise and also hydrotherapy is one of the oldest therapeutic method for the management of body physical dysfunction. Hydrotherapy has been advocated for the treatment of joint stiffness, painful scars, arthritis and adhesions as warm up with exercise. hydrotherapy is used due to the therapeutic properties of water for the effects on body tissues of heating, cooling, debridement, pain relief and relaxation of muscles. when hydrotherapy is not planned well or well performed, it can give side effects, especially on cardio-vascular system, this water therapy is used for the treatment of various diseases, additionally hydrothermal therapy has temperature effects, as in hot baths, saunas, wraps e.t.c. Mostly non-weight bea

TRANSCUTANEOUS ELECTRICAL NERVE STIMULATION (TENS) UNIT THERAPY

Image
WHAT IS TENS  Definition: Transcutaneous electrical nerve stimulation (TENS) unit is defined as low frequency analgesic physio-therapeutic modality which is designed based on control theory (i.e Gate theory of pain). WHAT IS TENS THERAPY TENS Therapy is the application of Electrotherapy modality or machine called transcutaneous electrical nerve stimulation (TENS) unit, which is using low frequency current mainly used for management and control of pain, both acute and chronic type. GATE THEORY OF PAIN Gate theory of pain is the theory which was described by Melzack and Wall in 1965, this theory explains about a pain-modulating system in which a neural gate present in spinal cord can open and close. therefore modulating the perception of pain. So this TENS unit modality was designed based on this "Gate theory of pain" for the therapeutic purpose of management and control of pain, both acute and chronic type. PRODUCTION OF TENS To produce the therapeutic effect of gate theory of
