Estudo comparativo na eficácia na dor aguda do T.E.N.S. e do gelo: uma revisão bibliográfica.

Abstract

The objective of this study is the physiological comparison between the two therapies , T.E.N.S and cryotherapy in the treatment compared to acute pain and understand more deeply each therapy.Cryotherapy is the transmission of sensory nerve impulses causing a block in place of all acute pain. The application of ice causes a reduction in the conduction velocity of nerve fibers , so that a necessary and effective therapy that applies for 30 minutes , occurs the main indications for the use of cryotherapy are acute injuries , muscle spasms and inflammatory processes , and to produce vasoconstriction deep tissue limiting bleeding , edema, and pain reduction .The T.E.N.S is characterized as a low frequency current , for pain relief , often from 5 to 150 Hz and pulse duration using 2-200 mS . There is a blockage of pain impulses transmitted along the fiber afferent A- δ and C ( gate control theory ) , and this can be modeled by T.E.N.S According to Melzack , Wall , and Castel . The analgesia occurs due to the stimulation of cutaneous sensory nerves is blocked by the gate mechanism, reducing pain. The Cryotherapy and more effective and as a form of treatment, while the TENS and an adjunct in pain.
