The investigators will select 48 individuals recruited non-probabilistically for convenience in HUOL. The sample calculation performed in G POWER software version 3.0.0.1 with 80% "power" defined the number of 40 individuals, adding to that number the 20% of possible losses during the survey. Allocation of the groups will be random, through the website http://www.randomization.com, which will include information such as sample size and number of groups. From this, the site will generate a specific coding for each group, randomly and in the form of blocks, with the following characteristics: sex, women in active cycle and use of oral contraceptives and use of analgesics. In this study, four groups will be considered: control-placebo group (gCP), cryotherapy group (gCrio), TENS Burst group (gTENSb) and Cryotherapy + TENS Burst group (gCrioTENSb). The four groups will receive educational sessions on chronic low back pain. The gCP will also undergo TENS bound in placebo mode, gCrio will undergo cryotherapy, gTENSb will undergo TENS in Burst mode and gCrioTENSb will undergo TENS Cryotherapy + Burst (combined). This protocol is in compliance with the recommendations of the Consolidated Standards of Reporting Trials - CONSORT (http://www.consort-statement.org/) for the execution of randomized clinical trials.
