Electromyographic Response to TsDcs in CNSLBP

Physiomed- IONOSON-Expert, Germany will be used to deliver SHAM direct current, The Physiomed- IONOSON-Expert, Germany is Two-channel electrotherapy including 21 currents, including direct current. The tsDCS electrodes will be rectangular pieces of saline-soaked synthetic sponge (7 × 8 cm, 56 cm2), to minimize chemical reactions at the electrode-skin interface. The anode will be placed over the spinous process of the eighth thoracic vertebra (T8) and the cathode will be placed on the second lumbar vertebra (L2) according to a modeling study which demonstrated that this configuration had a relevant impact on the distribution of the induced electric field (EF) in the lumbosacral spinal cord for the efficacy of tsDCS.

"1. Isometric exercises of spine~ * Hollowing in abdominals.~ * Isometric for back extensors.~2. Bridging exercises.~3. Graded active flexion exercises of spine~4. Graded active extension exercises of spine"

"For a sham tsDCS, the current will be ramped up for 30 seconds turned on for 5 s and then turned off in a ramp shaped fashion, thus inducing skin sensations indistinguishable from anodal tsDCS. This method was shown to achieve a good level of blinding among sessions.~These parameters for sham stimulation were chosen based on previous reports that the perceived sensations on the skin, such as tingling, fade usually out in the first 30 s of TsDcs ."
