Chapter 15: Therapeutic Modalities

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.

5. Physiological Variables of Crotherapy Variable Response to Therapy • Muscle spasm Decreases • Pain perception Decreases • Blood flow Decreases • Metabolic rate Decreases • Collagen elasticity Decreases • Joint stiffness Increases • Capillary permeability Decrease • Edema Controversial

11. Thermotherapy • Application of heat; Heat has the capacity to increase the extensibility of collagen tissue.

12. Physiological Variables of Thermotherapy Variable Response to Therapy • Muscle spasm Decreases • Pain perception Decreases • Blood flow Increase • Metabolic rate Increase • Collagen elasticity Increase • Joint stiffness Decrease • Capillary permeability Increase • Edema Increase

13. Comparing the Physiological Variables of Crotherapy and Thermotherapy Response to Response to Variable Cryotherapy Thermotherapy • Muscle spasm Decreases Decreases • Pain perception Decreases Decreases • Blood flow Decreases Increases • Metabolic rate Decreases Increases • Collagen elasticity Decreases Increases • Joint stiffness Increases Decreased • Capillary permeability Decreased Increases • Edema Controversial Increases

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.

16. Moist Heat Packs (Hot Packs) Duration: 15-20 minutes Indications: Subacute inflammation Chronic inflammation Reduction of subacute pain Reduction of chronic pain Subacute muscle spasm Chronic spasm Decreased range of motion Hematoma resolution Reduction of joint contractures Infection Contraindications Acute conditions Peripheral vascular disease Impaired circulation Poor thermal regulation Thermotherapeutic Methods

21. Acoustic Therapy:Ultrasound Indications • Acute and post acute conditions (non-thermal) • Soft tissue healing and repair • Scar tissue • Joint contracture • Chronic inflammation • Increased extensibility of collagen • Reduction of muscle spasm • Pain modulation • Increase blood flow • Soft tissue repair • Increase in protein synthesis • Tissue regeneration • Bone healing • Repair of non-union fractures • Inflammation of myositis ossificans • Plantar warts • Myofascial trigger points

22. Acute and post acute conditions (thermal) Areas of decreased temperature sensation Areas of decreased circulation Vascular insufficiency Thrombophlebitis Eyes Reproductive organs Pelvis immediately following menses Pregnancy Pacemaker Malignancy Epiphyseal areas in young children Total joint replacement Infection Acoustic Therapy:Ultrasound Contraindications

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.

26. Electrotherapy:Electrical Stimulation Duration • Duration: 10 to 30 minutes • Can be used with ice or heat

27. High Voltage or Pulsed Indications Peripheral nerve injuries, Delaying denervation delaying disuse atrophy Post-traumatic edema reduction Increase local blood circulation Joint contracture prevention Maintenance of range of motion Muscle strengthening Muscle spasm reduction Inhibitation of spasticity Muscle re-education Assist voluntary muscle function Interferential Indications Acute pain Chronic pain Muscle spasm Electrotherapy:Electrical Stimulation

Contraindications Demand-type pacemakers Over pelvic or lumbar areas During pregnancy Pain of central or unknown origin Areas of particular sensitivity carotid sinus laryngeal muscles pharyngeal muscles upper thorax temproal region cancerous lesions sites of infection Electrotherapy:Electrical Stimulation

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

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

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

32. 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. Massage Therapy

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

34. 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. Massage Therapy

35. 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. Massage Therapy

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

37. 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. Massage Therapy

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

39. 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. Massage Therapy
