interferential current treatment reduces low back pain and improves functionality in patients with chronic low back pain.

Conditions: Chronic Low-back Pain

Summary: . 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.

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.
