Cryotherapy Flashcards
What is used to estimate the stage of healing and use of cold?
Skin temperature
Skin temp elevated = use cold
normal skin temp= no cold (impairs healing and circulation)
Skin temp temp >72 hours= suspects infection, refer to MD
Cryotherapy should be applied after injury to control:
Bleeding
Edema
Pain
accelerates recovery
Cryotherapy needs to be applied within what time frame after injury to have an effect on the inflammatory process?
Within 5 minutes of injury
After 5 minutes, NO EFFECT because clotting has taken place
After 5 minutes post trauma, cryotherapy is only effective as a:
counterirritant (decrease pain and NCV)
antispasmotic (decrease muscle spindle activity, spasm)
Cryotherapy causes vasoconstriction via the release of what?
releases norepinephrine via the adrenergic receptors
Change in muscle force generation (time of application)
ice for <5 min = increase in isometric strength
ice for 30+ min = decrease in isometric strength for 1hr then increase for 3 hours
Cryotherapy is effective in what patient population?
RA
decreases histamine in blood = decrease inflammation
What are the contraindications for cryotherapy?
cold allergy/hypersensitivity cold intolerance Raynaud's disease Cryoglobulinemia Paroxysmal cold hemoglobinuria
Why effects does cryotherapy have on MS?
decrease tremor
improves strength
How long is cryotherapy applied for inflammation, edema, pain, muscle spasm, muscle contraction?
Inflammation/edema: 15 minutes (no longer than 20min)
Pain: 10-15 min (lasts for 1 hour)
muscle spasm: 5 min (DTR), 10-30 min (eliminate clonus)
What are the expected physiological responses to cryotherapy?
short term skin redness
analgesia
anesthesia
Always keep tissue temp above ___ degrees, and limit application to < ___ minutes
15 C (59F)
<45 min
