Ultrasound waves are widely used for diagnostic and therapeutic reasons.
Their use can have two kinds of effect:
Ultrasound produces important temperature changes as deep as one to five cm in underlying tissues of selected area, without excessive heating of the skin. Tissues with great collagen density such as joint capsules, scar tissue, tendons and fascia are heated more than others.
Thus we achieve:
- Reduction of muscle spasm
- Επιτάχυνση της παραγωγής Α.Τ.Ρ., που είναι το ενεργειακό νόμισμα των κυττάρων.
- Accelerating of the production of A.T.R., which is the energy currency of cells.Cyclic AMP derived from A.T.R. is very important secondary messenger who takes part in a great number of intracellular signal transduction pathways.
- More energy = acceleration of rehabilitation
- Separation of collagen fibres,
- increase in the stretching ability of connective tissue, of creped synovial capsule and the tendons
- Reduction of adhesions and scar tissue
- Increased permeability of the cell membrane to ions
- Effect on protein synthesis and accelerated healing of wound
- Decrease in edema
- Anti-inflammatory action
Phonophoresis is the use of ultrasound to enhance the delivery of topically applied drug molecules. Phonophoresis has been used in an effort to enhance the absorption of topically applied analgesics and anti-inflammatory agents in the inflamed tissues.
