Low frequency
A dry needling on trapezius muscle is performed, until two local twitch responses are obtained. The needle is kept inside the trigger point, as it will be the negative electrode, and an adhesive electrode will be added as the positive one. After that, a low frequency TENS is applied, at 2 Hz frequency and 120 microseconds of pulse width.
High frequency
A dry needling on trapezius muscle is performed, until two local twitch responses are obtained. The needle is kept inside the trigger point, as it will be the negative electrode, and an adhesive electrode will be added as the positive one. After that, a high frequency TENS is applied, at 12o Hz frequency and 200 microseconds of pulse width.
