A corrente interferencial pode ser entregue sobre a pele na forma bipolar dois eletrodos ou na forma tetrapolar quatro eletrodos. Este estudo trata-se de um ensaio cruzado, com amostra aleatorizada e cega. Os eletrodos utilizados eram de borracha-silicone com 4cm 2. A coleta de dados foi realizada em dias consecutivos.

Participaram do estudo 28 pacientes, sendo 14 no GI e 14 no GC. As treatment, physiotherapy stands out with a wide variety of techniques among them, for pain relief, electrotherapy is a useful tool.
This study aimed at comparing the analgesic effects of transcutaneous electrical nerve stimulation and interferential current in patients with chronic low back pain. Randomized clinical trial carried out between August and May in the clinic school of physiotherapy, Ulbra-Torres, with chronic low back pain patients. Patients were divided in two groups: intervention group IG treated with interferential current and control group CG treated with transcutaneous electrical nerve stimulation. Visual analog scale, Oswestry Questionnaire and Roland Morris Disability Questionnaire were used for baseline evaluation.
Patients were treated for five weeks, twice a week, in a total of 10 interventions. At the end, they were re-evaluated and one month after they were submitted to follow-up with the visual analog scale. Participated in the study 28 patients, being 14 in IG and 14 in CG. Sample was homogeneous intragroups for gender, age, color and mean pain duration.
There were positive results in chronic low back pain improvement both with transcutaneous electrical nerve stimulation and interferential current, without significant difference between transcutaneous currents.
