1. Chapter 15: Therapeutic Modalities

2. Therapeutic Modalities
In any rehabilitation program, modalities should be used primarily as adjuncts to therapeutic exercise and certainly not at the exclusion of range-of-motion or strengthening exercise.

3. Cryotherapy
Application of cold; the major therapeutic value of cold is its ability to produce anesthesia, allowing pain-free exercise. Cold as a therapeutic agent is a type of electromagnetic energy classified as infrared radiation. Wet ice is a more effective coolant because of the extent of internal energy needed to melt the ice.

4. Heating Response
Causes a slight temperature increase during cooling. The extent of cooling depends on the thickness of the subcutaneous fat layer.

14. Thermotherapy Special Considerations in the Use of Superficial Heat
Never apply heat when there is a loss of sensation
Never apply heat immediately after an injury
Never apply heat when there is decreased arterial circulation
Never apply heat directly to the eyes or genitals
Never heat the abdomen during pregnancy
Never apply heat to a body part that exhibits signs of acute inflammation

15. Thermotherapy Superficial tissue is a poor thermal conductor
temperature rises quickly on the skin surface as compared with the underlying tissues
There are limitations of superficial tissue
The deeper tissues, including the musculature, are not significantly heated because the heat transfer from the skin surface into deeper tissues is inhibited by the subcutaneous fat, which acts as a thermal insulator, and by the increased skin flow, which cools and carries away the heat externally applied.

23. Electrotherapy: Electrical Stimulation
Electricity is a form of energy that displays magnetic, chemical, mechanical, and thermal effects on tissue.
It implies a flow of electrons between two points.

24. Electrotherapy: Electrical Stimulation
All therapeutic electrical generators are transcutaneous electrical stimulators.
The majority of these generators are used to stimulate peripheral nerves and are correctly called transcutaneous electrical nerve stimulators (TENS).
Occassionally the terms neuromuscular electrical stimulator (NMES) or electrical muscle stimulator (EMS) are used; however, these terms are only appropriate when the electrical current is being used to stimulate muscle directly, as would be the case with denervated muscle in which peripheral nerves are not functioning.

25. Electrotherapy: Electrical Stimulation
Direct Current (DC current)
Flows in one direction only from the positive pole to the negative pole.
Direct current may be used for pain modulation or muscle contraction or to produce ion movement.

29. Massage Therapy
Sports massage causes mechanical, physiological, and psychological responses.

30. Massage Therapy Mechanical Response
Encourages venous and lymphatic drainage, mildly stretch superficial and scar tissue

31. Massage Therapy
Physiological Response
Reflex effects, relaxation, stimulation, and increased circulation

32. Massage Therapy
Psychological Response
The tactile system is one of the most sensitive systems in the human organism. Humans respond psychologically to being touched and is an important means for creating a bond of confidence between the athletic trainer and the athlete.

33. Massage Therapy Massage Strokes Effleurage Petrissage Tapotement
Vibration
Deep Friction

34. Massage Therapy Stroking; divided into light and deep methods.
Effleurage
Stroking; divided into light and deep methods.
Light stroking is designed primarily to be sedative.
It is also used in the early stages of injury treatment.
Deep stroking is therapeutic compression of soft tissue, which encourages venous and lymphatic drainage.

35. Massage Therapy
Petrissage
Kneading; a technique adaptable primarily to loosen heavy tissue areas such as the trapezius, latissimus dorsi, or the triceps.
Friction heat producing
Often used around joints and other areas where tissue is thin and is used on tissues that are especially unyielding such as scars, adhesions, muscle spasms, and fascia.

36. Massage Therapy
Tapotement
Percussion; produces an invigorating and stimulating sensation.

37. Massage Therapy
Vibration
Rapid shaking; rapid movement that produces a quivering or trembling effect.
It is used because of its ability to relax and soothe.
Although vibration can be done manually, the machine vibrator is usually the preferred modality.

38. Massage Therapy
Deep Friction
Often precedes activity, restoring mobility to a muscle.

39. Massage Therapy
Massage in sports is usually confined to a specific area and is seldom given to the full body.
The time required for giving an adequate and complete body massage is excessive in athletics.
It is not usually feasible to devote this much time to one athlete.
Five minutes is usually all that is required for massaging a given area.
