About

. 24 individuals were evaluated, with low back pain for more than 12 weeks and aged between 12 and 65 years. The current used in the lumbar region of the participants was of the tetrapolar interferential type and the stimulation mode was the automatic vector, carrier of 4,000 HZ, modulation frequency (AMF) of 50 HZ, sweep frequency of SWEEP of 20HZ. The assessment of pain and functionality was performed using the data collection instrument, the Visual Analogue Pain Scale (VAS), Rolland Morris Disability Questionnaire (RMDQ) and the Owestry Disability Questionnaire (ODQ) respectively. The present study demonstrates that treatment with interferential current promotes chemical improvement in participants, which opens up new perspectives on the use of this therapeutic approach.

Full description

Low back pain is characterized by pain and represents a change in health that affects mainly adults, although electrostimulation represents an important tool in the treatment of patients with chronic nonspecific low back pain, the clinical efficacy of the interferential current used in physiotherapy still lacks reinforcement for clinical validation. In this way, the present study evaluated whether the use of interferential current contributes to reducing chronic low back pain and analyzed whether the electrotherapeutic protocol can benefit the physical functionality of patients with chronic low back pain. 24 individuals were evaluated, with low back pain for more than 12 weeks and aged between 12 and 65 years. The current used in the lumbar region of the participants was of the tetrapolar interferential type and the stimulation mode was the automatic vector, carrier of 4,000 HZ, modulation frequency (AMF) of 50 HZ, sweep frequency of SWEEP of 20HZ. The assessment of pain and functionality was performed using the data collection instrument, the Visual Analogue Pain Scale (VAS), Rolland Morris Disability Questionnaire (RMDQ) and the Owestry Disability Questionnaire (ODQ) respectively. Data analysis was performed using the JAMOVI 2.2.5 software. Our data showed that individuals with interferential current showed significant improvement in pain relief, as well as in the functional pattern of pain improvement. The present study demonstrates that treatment with interferential current promotes chemical improvement in participants, which opens up new perspectives on the use of this therapeutic approach.

Experimental group

Description:

We used the SONOPULSE II device from the manufacturer IBRAMED, the electrodes measuring nine centimeters in length and five centimeters in width, from the manufacturer ARKTUS, of the adhesive plate type. According to the IBRAMED manual (2011, p. 47), the application is produced by two medium frequency currents through four electrodes, quadripolar method. The current type is tetrapolar interferential and the stimulation mode is automatic vector; the carrier frequency of 4000HZ, AMF modulation frequency of 50HZ, and the sweep frequency of SWEEP will be 20HZ. SWEEP sweep modes with 6 seconds of rise from the modulation frequency to the threshold the sweep frequency upon reaching the threshold immediately decays over the next 6 seconds. The positioning of the four-leaf clover type electrodes and the intensity of the strong current, however comfortable, according to the patient's report.

Control Group 01

Active Comparator group

Description:

he treatment is based on non-invasive methods, highlighting manual therapy techniques, especially joint manipulation therapy. Manual therapy techniques are adjustments in lumbar rotation. Joint adjustment is a controlled lever-like force with direction, amplitude, and speed that is applied to specific, tissue-adjacent joints. While joint mobilization is manual therapy without the impulse, the joint remains within the physiological range of motion (SILVA et al., 2012). Therefore, a high-velocity, low-amplitude (HVA) manual maneuver was applied. The thrust (impulse) is carried out in the para-physiological environment, between the physiological and anatomical barriers. preload phase before the manipulation, thrust phase where the maneuver is performed with high speed and low amplitude and the resolution phase where the manipulation ends. The maneuver is detailed by the authors Bergmann \& Peterson (2010).
