21
Q

goals for ice (6)

A

↓ pain
Reduce inflammation or swelling
Alleviate muscle spasm
Reduce spasticity
Management in multiple sclerosis
Cryostretch- muscle spasm

22
Q

Physiological effects of ice (5)

A

Decrease meeatbolism=decrease inflammation and edema
decrease muscle spasm
decrease nerve conduction velocity
decrease pain/increase pain thereshold
increases joint stifffness

23
Q

AE with small cold application (5)

A

Facial flush, puffiness in eyelids, respiratory problems, in severe cases anaphylaxis (decreased blood pressure, increased heart rate) with syncope

24
Q

Raynaud disease treatment (3)

A

avoid cold
Calcium channel blockers
phosphodiesterase inhibitiors

25
Q

contraindictors for cold (8)

A

Cold hypersensitivity (urticarial)
Cold intolerance
Cryoglobulinemia- proteins stick together in the cold
Peripheral vascular disease
Severe impaired temperature sensation
Raynaud’s diseases
Paroxysmal cold hemoglobinuria
Over regenerating peripheral nerves

26
Q

vapo-coolant method

A

evaporation

27
Q

goal for vapo-coolant

A

reduce muscle spasm and desentize trigger points

28
Q

what to do after vaop-coolant

A

Passively stretch after application, then apply moist heat

Have patient perform active exercise after application of moist heat

29
Q

dosage for contrast bath

A

Continue sequence 5-6 times of 4:1 (warm:cold) usually ending in warm water, but may end with cold if goal is edema reduction

30
Q

physiological effects for pulsed (nonthermal) short wave diathermy (2)

A

Increased cell growth and phagocytosis
May help healing of wounds and diabetic ulcers

31
Q

indications for short wave diathermy (nonthermal) (4)

A

Pain control
Decrease edema
Resolution of acute and chronic infections
Wound control and soft tissue healing

32
Q

which wave you have to cover with a towel

A

shortwave
