The same physician blinded to randomization evaluated all the patients before treatment, and on the first and twelfth week after the end of the treatments. After evaluation by the physiatrist the patients were randomized into three groups: 
Group 1: The patients in this group were applied interferential current with vacuum electrodes (n = 34) and exercise therapy.
Group 2: The patients in this group were applied interferential current with carbon-silicone pad electrodes (5x5 cm)  and exercise therapy.
Group 3 (control group): The patients in this group have performed only exercise therapy, Blinding description: Casual randomization using sealed numbered envelopes without strata or blocks was performed by an administrative assistant.

      <hc_freetext>Low back pain (Pain between 12th rib and gluteal fold)- nonspesific origin.</hc_freetext>
      <i_freetext>Intervention 1: Intervention group 1: The patients in this group were applied interferential current with vacuum electrodes (n = 34). Four vacuum electrodes were placed so that the painful area remained in the middle. The sponges were wetted with tap water and placed  in the electrode cups. To apply the electrodes to the patient, the cups were slightly squeezed, brought into contact with the skin and held there for a few minutes until suction occurred. Before application of IFT, hot pack was applied for 20 minutes to the low back. The patients in this group also received exercise therapy. Intervention 2: Intervention group 2: The patients in this group were applied interferential current with carbon-silicone pad electrodes (5x5 cm) (n = 34). Treatment of subjects with bilateral LBP involved paraspinal application of the cathode and anode electrodes at the lateral limits of the painful area parallel to the vertebral column. The sponges for the pad electrodes were wetted with tap water and placed them to the area to be treated using straps in the electrode cups.  Before application of IFT, hot pack was applied for 20 minutes to the low back. The patients in this group also received exercise therapy. Intervention 3: Control group: The patients in this group have performed only exercise therapy and hot pack was applied for 20 minutes to the low back (n = 32). Patients were requested to do core strengthening and spine stabilization exercises. The stabilization training  included: activation techniques for the neutral spine position, training the activation transversus abdominis, external and internal obliques, training the activation diaphragmatic breathing, myofascial release techniques for the erector spinae muscle, exercising the coordination of superficial and deep trunk muscles, and postural and dynamic training. The exercises were performed 5 times a week. The duration of a training session was 45 min (each exercise once a day with 20 repetitions).</i_freetext>

Does The Application of Interferential Current Therapy with Vacuum Electrodes Provide Additional Effect in Patients with Nonspecific Chronic Low Back Pain? A Randomized Controlled Study

This is a scientific study which was being conducted  to evaluate effectiveness of interferential current therapy on pain, disability and quality of life in patients with chronic low back pain  and to compare the advantages of application IFT with vacuum and carbon silicon pad electrodes to each other.
