NCT03179488

Brief Summary

The intensity used during transcutaneous electrical nerve stimulation (TENS) in both, clinical practice and research studies, is often based on subjective commands such as "strong but comfortable sensation". There is not consensus regarding the effectiveness dose of TENS

Outcome Measures

Primary Outcomes (2)

  • Baseline Current Density

    Current density (mA/cm2) is obtained by a mathematical operation which reflects the applied current intensity divided by the electrode area (45cm2)

    At the onset (0min) of the Spinal TENS session

  • Final Current Density

    Current density (mA/cm2) is obtained by a mathematical operation which reflects the applied current intensity divided by the electrode area (45cm2)

    At the end (40min) of the Spinal TENS session

Secondary Outcomes (9)

  • Baseline Maximal peak-to-peak soleus H-reflex

    baseline at 0min

  • Baseline Maximal peak-to-peak soleus M wave

    baseline at 0min

  • Baseline Normalized H-reflex response

    baseline at 0min

  • During Maximal peak-to-peak soleus H-reflex

    during treatment at 33min

  • During Maximal peak-to-peak soleus M wave

    during treatment at 33min

  • +4 more secondary outcomes

Study Arms (2)

Spinal TENS stimulation

EXPERIMENTAL

Spinal TENS stimulation: A constant voltage and a symmetric biphasic current of 200 microseg pulse-width at a frequency of 100Hz. The intensity will increase until participants report a "strong but comfortable" sensation, just below motor threshold.

Device: Spinal TENS

Sham stimulation

SHAM COMPARATOR

The same procedures as experimental group, but but will be applied a sham electrical stimulation increasing the current intensity until sensory perception of the stimulus, and then decreased to zero where it will fix until the end of the stimulation.

Device: Sham stimulation

Interventions

Spinal TENS stimulation over back through the electrotherapy device Myomed 932. (Enraf-Nonius, Delft, Netherlands)
