A
  • Muscle spasms (especially low back)
  • Myalgia
  • Refractory pelvic inflammatory disease
  • Chronic prostatitis
21
Q

How does cold decrease spasticity?

A

– Dec muscle spindle activity—dec firing rates of Ia and II afferent fibers
– Dec Golgi tendon organ activity—dec firing rates of Ib afferent fibers

22
Q

What is cold evaporation used for?

A

Spray-and-stretch techniques to treat myofascial and musculoskeletal pain

23
Q

What are effects of UV radiation on wounds?

A

Increased vascularization of wound margin

24
Q

What are indications of UV radiation treatment?

A

Psoriasis treatment—utilizes Goeckerman’s technique, where a coal–tar ointment is applied to the skin prior to UV treatment

25
Q

What are precautions of UV radiation treatment?

A

Scars

Atrophic skin

26
Q

What are the doses of UV radiation treatment?

A

Minimal exposure time required to cause erythema on the volar surface of the forearm—measured in minimal erythema dosage (MED)

27
Q

What % of TENS unit pain control is from placebo effect?

A

30-35%

28
Q

What is the proposed mech of pain control with TENS unit?

A

Gate control theory

29
Q

What is the most effective type of TENS?

A

High-frequency, low-intensity stimulation

30
Q

What are clinical uses of NMES?

A

Strengthens muscles and maintains muscle mass after immobilization

31
Q

What are benefits of NMES?

A

Inc muscle mass, stroke volume (SV), and cardiac output (CO), as well as reduce venous pooling

32
Q

What is iontophoresis?

A

Transdermal delivery system in which a substance bearing a charge is propelled through the skin by a low electrical current

33
Q

What are reflexive effects of massage?

A
  • Reflex vasodilation with improvement in circulation

* Dec in pain by means of the gate control or release of endogenous opiates

34
Q

What are mechanical effects of massage?

A

Assist in venous blood return from the periphery to the central nervous system

35
Q

What is effleurage?

A

Gliding, rhythmic strokes of the hand over the skin in a distal to proximal direction

36
Q

What is Pétrissage?

A

“Kneading” technique in which the muscle tissue is “pinched” with the fingers and lifted from its underlying origin

37
Q

What is Tapotement?

A

Percussion

38
Q

What is Friction massage?

A

Prevents adhesions in acute muscle injuries and breaks adhesions in subacute and chronic injuries

39
Q

What is Soft-tissue mobilization?

A

Forceful massage of the fascia-muscle system

40
Q

What is Myofascial release?

A

Prolonged light pressure is applied in specific directions of the fascia system to stretch focal areas of muscle or fascial tightness

41
Q

What is Acupressure?

A

Finger pressure is applied over trigger points or acupuncture points to decrease pain

42
Q

What is Thrust?

A

Impulse, high velocity, low amplitude, final activating force is from the operator

43
Q

What is Articulation?

A

Low velocity, high amplitude

44
Q

What is Muscle energy?

A

(direct isometric type): Patient contraction is the final activating force.

45
Q

What is Direct myofascial release?

A

Tissue is held in a loaded, stretched position until muscle is released

46
Q

What is Vertebral joint distraction?

A

Elongation of the cervical spine of 2 to 20 mm; can be achieved with 25 pounds or more of tractive force

47
Q

What are contraindications of cervical spine traction?

A
  • Cervical ligamentous instability
  • Infectious process of the spine
  • Cervical spinal stenosis with significant cord compromise

A

> 25 lbs

49
Q

What amount of traction is needed for the lumbar spine?

A

> 50 lbs
