Effect of Dry Needling Plus Vibration on Myofascial Trigger Points in Individuals With Nonspecific Low Back Pain

In the PS+V technique, no movements will be performed with the needle once it is correctly inserted. Instead, only vibratory stimulus will be applied for 10 minutes. Since this is a completely novel technique, the optimal duration of application is not yet known; however, it is considered that 10 minutes may be sufficient to demonstrate an effect.

"In the conventional PS technique, the needle will be inserted into the MTrP using the fast-in and fast-out technique described by Hong (1994) at an approximate frequency of 1 insertion per second (1 Hz) without completely withdrawing the needle from the skin. This technique will be maintained for 30 seconds in an attempt to elicit a local twitch response. After the procedure, the treated area will be firmly compressed with a cotton pad for three seconds."
