Dry Needling and Low-level Laser Therapy to Treat Myofascial Pain

Summary

Myofascial Pain is a clinical condition of myalgic pain characterized mainly by the presence of Myofascial Trigger Points. Trigger points can be active or latent and they are described as a hypersensitive spot within a taut band in the muscle. The use of a computer for long periods has been shown as a trigger the trigger points. Dry Needling and Low-Level Laser Therapy (LLLT) has been described as good resources to treat myofascial pain. The hypothesis is that the association of the purposed interventions will have greater effects than only the dry needling intervention. The objective is to evaluate the effects of the dry needling and the laser in the treatment of upper trapezius trigger point on women. This study is composed of an evaluation and an intervention proposal with dry needling and LLLT to treat myofascial trigger points. The sample will be composed of 60 women, with 18 to 65 years old, divided into three groups. Twenty individuals will be in group Dry-On that will receive dry needling intervention on the trigger point, followed by LLLT intervention on. Twenty individuals will be in group Dry-Off that will receive dry needling intervention on the trigger point, followed by LLLT intervention turned off. Twenty individuals will be in group Control that will receive dry needling intervention at 1.5 cm from the trigger point, followed by LLLT intervention turned off. All interventions will be performed in one session. Outcome measures for pain, pressure pain threshold, functionality, and muscle activity will be collected.

Interventions

OTHER

Dry Needling

It will be used acupuncture needles, individually packaged and sterilized, with 0.25 mm of thickness and 0.40 mm of length. The therapist will perform the grip in upper trapezius on the site of one of the two previously marked locations, according to the subject group allocation, and will insert the needle in the skin with help of a guide tube and will deepen the needle approximately 10 to 15 mm inside the trigger point. The needle will be moved up and down as in the "fast-in and fast-out" technique described by Hong and the movement will be repeated during 30 seconds in a cadence of approximately 1 Hz. The protocol will be the same for the groups that will receive the application directly on the trigger point and for the group that will receive the application away from the trigger point

DEVICE

Low-Level Laser Therapy

The laser protocol used the PainAway Laser™ cluster equipment composed of one pulsed infrared laser of 905 nm, four red LEDs of 640 nm, and four infrared LEDs of 875 nm, with full device aperture of 4 cm2, total delivered energy of 39,8 J, a magnetic field of 35 Mt and treatment time of 300 seconds. The equipment was turned on only for the DNP group and it remained in slight contact with the skin during 300 s for all groups.
