Energo-Neuro Adaptive Regulator: SCENAR


SCENAR is an advanced form of electrotherapy and may be effective in treating acute and chronic pain. SCENAR therapy functions on two physiological principles: that the body has its own healing capabilities and that it is continually employing processes of self-regulation to maintain health.

The SCENAR device is a small, hand-held device with transdermal electroneuro-stimulator, graphic display (Professional models), light emitting diodes (models for home use) and audible indications. It delivers non-invasive, computer-modulated therapeutic electro-stimulation via a patient’s skin and involves high amplitude, short-duration waveforms with little discomfort to patients. Due to this device’s high amplitude, small unmyelinated ‘C’ fibres can be stimulated to a higher degree than with other forms of electrotherapy. When sufficiently stimulated ‘C’ fibres trigger neuro- and regulative-peptide release with resultant pain relief and healing. The SCENAR impulse is carried via afferent nerve fibres to regulatory centres in the brain which in turn responds via efferent nerve fibres. SCENAR interprets this response and, via computer modulation, results in its next impulse being modified accordingly which further provides information back to the brain to either amplify or dampen the pathological signals initiating pain, ultimately leading to homeostasis. SCENAR therapy protocols include rating of pain, measurement of range of movement and testing of movement related to functional impairment.

The SCENAR device is small, portable, user-friendly, safe, and is relatively low-cost. Patients may benefit from faster recovery times, versatility and no concurrent medication interactions. The SCENAR has been cleared for marketing by the FDA for use in treating Chronic & Acute Pain.
