Summary

This study aim analyze the immediate effects of conventional transcutaneous electrical nerve stimulation (TENS) and Burst TENS combined or not with cryotherapy in patients with non-specific low back pain. All subjects will be submitted to an evaluation of the painful sensation, through the numerical rating scale, and pain threshold, through algometry, before, immediately after the intervention and 25 minutes after.

Conditions

• Low Back Pain, Mechanical

Interventions

Type	Name	Description
DEVICE	Conventional TENS	Transcutaneous Electrical Nerve Stimulation (frequency of 100 Hz, pulse duration of 100 micro-seconds and sensory-level amplitude) with two electrodes in each side of the lumbar spinal.
DEVICE	Burst TENS	Burst-modulated TENS with carrier frequency of 100 Hz, burst-modulated at 4Hz, pulse duration of 200 micro-seconds and motor-level amplitude.
OTHER	Cryotherapy	1,5 Kg of crushed ice pack on lumbar spine.
DEVICE	Burst TENS + Cryotherapy	Burst-modulated TENS with carrier frequency of 100 Hz, burst-modulated at 4Hz, pulse duration of 200 micro-seconds and motor-level amplitude plus 1,5 Kg of crushed ice pack on lumbar spine.
DEVICE	Conventional TENS + Cryotherapy	Transcutaneous Electrical Nerve Stimulation (frequency of 100 Hz, pulse duration of 100 micro-seconds and sensory-level amplitude) plus s 1,5 Kg of crushed ice pack on lumbar spine.
OTHER	Placebo TENS	TENS device turned on, but with zero amplitude.
