Eksperimentel: Theta Burst Protocol
The intervention consists of the bilateral, ultrasound-guided insertion of a needle for percutaneous electrical nerve stimulation (PENS), following a theta-burst pattern designed to produce long-term potentiation-like effects.
An asymmetric biphasic compensated current with a rectangular positive phase and a triangular negative phase is applied at a frequency of 100 Hz for 5 seconds, followed by 55 seconds of rest, repeated five times.
The pulse width is 240 µs, and the intensity is maintained above the motor threshold and below the pain threshold.

Eksperimentel: 10-10-10 Protocol
The intervention consists of the bilateral, ultrasound-guided insertion of a needle for percutaneous electrical nerve stimulation (PENS).
An asymmetric biphasic compensated current is applied, with a rectangular positive phase and a triangular negative phase, at a frequency of 10 Hz, pulse width of 240 µs, and an intensity above the motor threshold and below the pain threshold.
Each stimulation period lasts 10 seconds, followed by 10 seconds of rest, repeated ten times.
|
Percutaneous electrical nerve stimulation (PENS) applied under ultrasound guidance at 10 Hz, consisting of 10 seconds of stimulation followed by 10 seconds of rest, repeated ten times.
The current intensity is adjusted to produce visible muscle contraction without pain.
|
|
Eksperimentel: 5-55 Protocol
Ultrasound-guided PENS protocol applying a 100 Hz stimulation for 5 s followed by 55 s of rest, repeated five times.
The intensity is adjusted to a tolerable tingling sensation, below the pain threshold.
|
Percutaneous electrical nerve stimulation (PENS) applied under ultrasound guidance at 100 Hz for 5 seconds, followed by 55 seconds of rest, repeated five times.
The current intensity is adjusted to elicit a mild tingling sensation while remaining below the pain threshold.
|
|
Eksperimentel: HIB Protocol (High-Intensity Burst)
Ultrasound-guided PENS protocol consisting of high-intensity bursts applied bilaterally at a current intensity close to 1000 mA, repeated three times.
The intensity is set individually, approaching but not exceeding the participant's tolerance threshold.
|
Percutaneous electrical nerve stimulation (PENS) applied under ultrasound guidance using high-intensity bursts delivered bilaterally at a current intensity close to 1000 mA, repeated three times.
The stimulation intensity is individually adjusted to approach but not exceed the participant's tolerance threshold.
