Effects of Percutaneous Peripheral Nerve Stimulation on Neck and Low Back Pain

The ultrasound guided percutaneous peripheral nerve stimulation will be applied to the Spinal or Inferior Gluteal and Tibial Nerve. The parameters will be 5 trains of 5 seconds, 55 seconds apart, at a frequency of 100Hz, making 5 minutes of total treatment. The intensity will be set 200 microamperes (μA) above the detection threshold for each patient, guaranteeing a sensitive but not painful perception.

The ultrasound guided percutaneous peripheral nerve stimulation will be applied to the Spinal or Inferior Gluteal and Tibial Nerve. The parameters will be 40 trains separated by 7 seconds from each other, where each train contains 5 trains separated by 200ms, at a frequency of 5Hz, resulting in 6 minutes and 45 seconds of total treatment. The intensity will be set at the motor threshold of the patient, ensuring a non-painful stimulation.

The transcutaneous electrical nerve stimulation will be applied on the trapezius or low back and internal calf muscles at a frequency of 80Hz and a pulse width of 250 microseconds, for 15 minutes. The intensity will be set at the detection threshold of each patient generating a sensitive but non-painful perception.
