Short Answer

11. It is a thermotherapy in which dry heat is transferred to the body part through convection with a suspended airstream.

12. Traction stretches ligament and joint capsule, stretches spinal and paraspinal muscles, increases the separation of the articular facet joints, and relieves pressure in nerves and nerve roots.

13. Decreasing swelling, increasing muscle strength, retarding muscle atrophy, and muscle reeducation.

14. Electrical current produced by applying pressure to certain crystals in the transducer head.

15. Hunting response.

16. Anesthesia, vasoconstriction, decreased metabolism, muscle spasm, muscle fatigue, and free-nerve ending excitability.

17. 10 Minutes

18. Raynaudπs phenomenon

19. Decrease muscle atrophy, decrease swelling, reeducate movement, decrease pain, introduce anti-inflammatory and analgesic drugs through iontophoresis, and localize trigger points.

20. To relieve chronic pain and allow pain-free exercise.

21. Increase circulation and metabolism, encourages venous and lymphatic drainage, stretches connective tissue and prevents rigidity in scar formation; also aids in relaxation.

Essay

39-42. Thermal—heat increases collagen tissue extensibility, alters blood flow, changes nerve conduction velocity, elevates pain threshold, raises enzymatic activity, and changes muscle contractibility.

Mechanical--causes micromassaging to occur, which disperses and agitates the molecules and causes a fiber separation in the collagen fibers.

Chemical—increases capillary permeability and increases adenosine triphosphate (ATP).
