|
effects of cryotherapy |
pain relief, fever reduction, control of bleeding, reduce inflammation, decrease muscle spasm, decrease pain to increase muscle contraction |
|
|
conduction depth |
4cm |
|
|
higher water content means _____ conductivity |
increased, muscle>fat |
|
|
lowering skin temp to 13.6 C 10 C |
local analgesia reduction in NCV |
|
|
sequence of stages |
cold, burning, aching, numbness |
|
|
convectino |
moving particles of fluid or air |
|
|
hemodynamic effects of cold |
vasocontriction , cold on smooth muscle decrease in vaspdilating NT's reflexive increase blood viscosity (can effect contralateral limb) |
|
|
lasts of to 15min |
redness, oxyhemoglobin |
|
|
hunting response |
falls below 10C, substance H releases, promotes vasodialation |
|
|
24-48 hrs cold is modality of |
choice |
|
|
block a delta fibers first |
yay |
|
|
within 30 minutes |
decrease strength bloddflow NCV increase in tissue viscosity, joint stiffness |
|
|
after 30 minutes |
increase strenth, bloodflow, pain threshold |
|
|
affects on propioception |
increase M-L sway decrease in SLS |
|
|
neuromuscular effects |
facilitates alpha motor fibers decreases gamma motor firing decreases spacitiy |
|
|
PRICE |
protect, rest, ice, compress, elevate, stabilize |
|
|
2 theroies for decreasing pain, |
1. cold stimulates thermal receptors that overrides pain C fibers 2. decrease in afferent input(decrease) NCV |
|
|
Contraidications |
cold intolerance- rheumatic disease cold induced urticarial- allergic to cold cryoglobulinemia- clotting like gel Raynauds disease- vasospastic disorder, digital cyanosis regenerating peripheral nerves compromised circulation non-inflammatory edema |
|
|
precautions |
superficial nerves open wounds hypertension decreased sensation cognitive very young or old |
|
|
cold packs |
