Myofascial trigger point (MTrP) might play an important role in the formation of mechanical neck pain and is known as a hyperirritable spot in skeletal muscle that is accompanied with a hypersensitive palpable nodule in a taut band.~dry needling and iontophoresis play a major role in the treatment of mechanical neck pain so this trial was conducted to determine which one has superiority. this trial has three groups. two experimental and one control group.pain, function, pressure pain threshold and emg will be measured
the aim of this trial is to compare dry needling and magnesium sulphate iontophoresis in subjects with mechanical neck pain
