Effect of Dry Needling on Myofascial Trigger Point

Inclusion Criteria: * 1\. Presence of a palpable taut band in muscle. * 2\. Presence of a hypersensitive tender spot in the taut band. * 3\. Reproduction of the typical referred pain pattern of the MTP in response to compression. To detect active TrPs, TrP pressure tolerance was assessed using a mechanical pressure algometer. The investigator applied continuous pressure with the algometer with an approximate pressure of 2.5 kg/cm2. * 4\. Spontaneous presence of the typical referred pain pattern and/or patient recognition of the referred pain as familiar. * 5- Pain of at least 30 mm on a visual analogue scale (VAS). The selected MTP of the UT muscle was located in the middle of the more nearly horizontal fibers of the UT 40. Exclusion Criteria: * had a history of fibromyalgia syndrome, whiplash injury, cervical spine surgery and fracture, cervical radiculopathy, having therapy within the past month before the study * any systematic disease such as rheumatism and tuberculosis or cervical myelopathy, multiple sclerosis * local infection, * pregnancy * taking anticoagulants (e.g. warfarin) * long-term steroid using
