Intervention / Treatment
Detailed Description
The general configuration of the study consists of a study before and after the block of sessions to be determined, and differences of all the variables measured before and after NESA therapy will be compared through the mechanisms of somatosensory evocations.
Given its potential use, the objective of this study is to determine if there are changes in the somatosensory evoked potentials of the ulnar, median, tibial, peroneal and vagus nerves when non-invasive neuromodulation NESA is applied, which is used as a physiotherapy treatment. for objectives such as pain, vegetative affectations and sleep disorders.
The variables of the study will be collected at two time points: before the intervention and at the end of the intervention.
The statistical analysis will be an intention-to-treat analysis. For the main outcomes variables a two factor ANOVA will-be performed (intervention-time) with a post-hoc analysis with kruskal wallis correction correction. Statistical significance will be defined as p <0.05

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Non-invasive Neuromodulation
Non-invasive Neuromodulation Intervention with microcurrents: application of 6 electrodes per extremity and an adhesive electrode at C7 level.
|
The electrodes will be placed with the help of gloves and adapted socks for 1 hour, twice a week, until 10 intervention sessions are completed.
In addition, depending on the session, an adhesive electrode will be placed at the level of C7.
Characteristics of microcurrents: pulsed monophasic rectangular wave with a pulse of 1.3 s and pause of 300 ms, voltage 3 mV and intensity 0.5 μA.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Response speed of the central and peripheral nervous system to a stimulus 1
Time Frame: Up to 1 month
|
The Somatosensory Evoked Potentials of both median and ulnar nerves will be evaluated. Neurophysiological tests of the nervous system that functionally assesses the nerve pathways of the central and peripheral nervous system. For its evaluation, distal stimuli are generated in the wrists in the range of 3-4Hz with intensities above the sensitive threshold and below the pain threshold. |
Up to 1 month
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Response speed of the central and peripheral nervous system to a stimulus 2
Time Frame: Up to 1 month
|
Somatosensory Evoked Potentials of both Posterior Tibial and Peroneal nerves will be evaluated. Neurophysiological tests of the nervous system that functionally assesses the nerve pathways of the central and peripheral nervous system. For its evaluation, distal stimuli are generated in the wrists in the range of 3-4Hz with intensities above the sensitive threshold and below the pain threshold. |
Up to 1 month
|
Response speed of the central and peripheral nervous system to a stimulus 3
Time Frame: Up to 1 month
|
Somatosensory Evoked Potentials of the sensory auricular branch of the vagus nerves will be evaluated. Neurophysiological tests of the nervous system that functionally assesses the nerve pathways of the central and peripheral nervous system. Stimulations and recordings will be carried out only in the left auditory pavilion (since the right, due to the connection with the sinoatrial node of the heart by means of vagus efferences, can cause, according to the reports consulted, alteration of the heart rhythm and presyncope). Stimulations will be performed by means of a needle connected to the stimulator equipment, or in the tragus, by means of atrial surface electrode or auriculotherapy needle dipole. |
Up to 1 month
|
Response speed to sensitive stimuli in the palms of the hand and sole of the feet
Time Frame: Up to 1 month
|
Several simultaneous bilateral recordings after stimuli in the palms of the hand and sole of the feet above the sensory threshold in the limb contralateral to the recording, with a time between stimuli greater than one minute, to avoid habituation of the response. The latency of the first maximum deflection, in millivolts. |
Up to 1 month
