this study will be conducted to investigate the effect of Extracorporeal Shockwave Therapy on Ultrasonography Changes of Upper Trapezius Myofascial Trigger Points in Patients With Non Specific Neck Pain
Neck pain is one of the most commonly reported musculoskeletal disorders. The prevalence for neck pain varies between 16.7% and 75.1% in the general population. Up to 67% of world's population may present chronic non-specific neck pain at least once in their lives. The upper trapezius is probably the muscle most often beset by trigger points, it is indicated that the upper trapezius is the most sensitive of 8 different muscles (upper trapezius, pectoralis major, levator scapulae, teres major, supraspinatus, gluteus medius, infraspinatus, paraspinal) to the pressure of an algometer.Recently, the extracorporeal shock wave has been widely known to be an effective therapeutic modality in myofascial pain syndrome treatment and a systematic review provided promising insight into the effectiveness of ESWT in Myofascial pain syndrome treatment. sixty patients with non specific neck pain will be assigned randomly to two groups; first one will receive shock wave therapy and traditional therapy and the second one will receive traditional therapy only for six weeks.

Enrollment
60
the patients will receive Extracorporeal Shockwave therapy sessions by 600 impulses with 1.6 bar pressure at a frequency of 8 Hz on site of the upper trapezius
the patients will receive Traditional physical therapy in the form of Integrated neuro-muscular inhibition technique + posture correction and scapular stabilization exercises.
muscle thickness
Ultrasonography device will be used to assess muscle thickness
Time frame: up to six weeks
hypoechoic area intensity
An ultrasonography device will be used to assess the hypoechoic area intensity
Time frame: up to six weeks
neck disability
Arabic version of neck disability index will be used to measure neck disability. It consists of 10 questions: pain intensity, personal care, lifting, reading, headaches, concentration, work, driving, sleeping, and recreation. 5 Each item is scored from 0 (no disability) to 5 (total disability). The maximum possible score is 50.
Time frame: up to six weeks
pressure pain threshold
Digital algometer will be used to measure pressure pain threshold
Time frame: up to six weeks
cervical range of motion
The cervical range of motion (CROM) device will be used to measure cervical ROM
Time frame: up to six weeks
pain intensity
The visual analog scale (VAS) will be used to measure pain intensity. it is a10 cm line, oriented vertically or horizontally, with one end representing "no pain" and the other end representing pain as bad as it can be
Time frame: up to six weeks
