Abstract

Lumbar disc herniation is characterized by chronic and persistent pain for more than 3 months, considered neuropathic pain, with sensory and motor changes causing sensitivity, consequently loss of muscle mass leading to decreased functionality, affecting the individual's quality of life. Treatment may be medication and/or rehabilitation, using physiotherapeutic resources, such as transcutaneous electrical nerve stimulation, functional electrical stimulation (FES) and photobiomodulation. FES generates a sequence of electrical stimuli in a coordinated and sequenced manner, triggering action potentials in intact peripheral nerves and activating muscle contractions. Photobiomodulation produces antioxidant action that protects the body against free radicals and anti-inflammatory activity with increased synthesis of ATP and others factors. Thus, the synergistic use of these resources was possible through equipment developed by the Institute of Physics of São Carlos, which allows irradiation perpendicular to the surface of the skin. The objective of this study was to evaluate the new device in a patient with lumbar radiculopathy due to disc herniation, with symptoms of pain and decreased strength. Visual analogue scale (pain), quality of life by Short Form 36 questionnaire, range of motion (goniometer), sensorimotor functions and degree of functional limitation (Fugl-Meyer Scale and Roland-Morris Disability Questionnaire) were used. Therefore, the synergistic effect of FES and photobiomodulation was directed both for the anatomical projection area of the vertebral segment and along the corresponding myotome in lumbar region (L5-S1 myotomes), for 30 minutes (10 sessions; twice a week). A decrease in low back pain, greater range of motion of the lumbar spine, improvement of sensorimotor function and improved quality of life leading to less functional disability. Therefore, the new equipment can be used in individuals with lumbar disc herniation, an innovative resource that can reduce the time of sessions and physical therapy treatment.
