High-power laser therapy: High power laser therapy (HPLT) with a neodymium-yttrium aluminum garnet laser with a pulsating waveform produced by a ( Hilterapia device , ASA, Arcugnano, Vicenza, Italy). It will be set at the following parameters: Nd:YAG laser with pulsed emission (1064 nm), very high peak powers with average power 6 W, high levels of fluency (760 mJ/cm energy density), short pulse duration (250 μs), low frequency (10-40 Hz), and 5-cm probe diameter for 15 minutes.
The scanning will be performed longitudinally \&transversely from the C3 to C7 posterior neck in the paraspinal region, upper back, inter-scapular area, trapezius, sternocleidomastoid muscles, and posterior \& lateral shoulder areas
Placebo (PL) high power laser: laser probe scanning will be applied to the same areas as that applied in the HPLT procedure. PL will be applied while the lights of the device will be on, with no current flowing through the device. Placebo therapy will be applied at the same frequency as HPLT (Three sessions a week for six weeks for a total of 18 sessions; one session will be lasted 15 minutes).
Conventional physical therapy program: A specific program of 45-min exercise of three sessions a week for six weeks for a total of 18 sessions. Corrective exercises will be performed initially by stretching exercises for(suboccipital, upper trapezeius, scalene, levator scapulae, sternocleidomastoid, pectoralis major/minor muscles) will be given four repetitions with 30 second hold. each with 3 seconds rest between each stretch Then, strengthening exercises will be performed initially in an isometric manner for weak muscles (deep cervical flexors, rhomboidus, and lower trapezeius muscles) will be done initially without weight and afterward by using Theraband and dumbells. All patients will be instructed to achieve three sets of 12 repetitions of the strengthening exercises (isometrics exercises) with 1 to 2 minutes rest in between each set. Contraction will be held for 5 seconds/repetitions. 10-20 repetitions for strengthening exercises and 3 sets of 30 repetitions for endurance exercise

Primary outcome measure(s)
Myoelectrical activity of suboccipital muscle — 6 weeks Needle electromyography (EMG, Micromed, made in Italy) is a definitive invasive technique that allows an objective evaluation of muscle activity.
Activation pattern of the suboccipital muscle mainly the rectus capitis posterior muscles will be recorded and analyzed. The skin is cleaned with alcohol to reduce skin impedance. A Concentric needle is inserted in the rectus capitis posterior muscles, positioned caudad, at a point 1-2cm lateral to the midline at the level of the approximation of the posterior arch of C1. at approximately 80 degrees from an imaginary line drawn parallel to the surface of the skin in the mid-sagital plane. The patient performed extension delivering maximum voluntary contraction against therapist hand. Reference electrode is placed just above the middle of the spine of the right scapula or over the forehead. Data will be represented as interference patterns (graphics), analyzed and compared before and after the intervention for all participants in the study.
Neck Disability Index (NDI) — 6 weeks The NDI will be used to assess neck pain and quality of life for all participants before and after the treatment program. It is consisted of 10 items with six potential responses per item relating to pain severity, headache, attention, and various physical activities (lifting, personal care, recreation, work, driving, reading, and sleeping). Each item's score ranges from 0 to 5. The maximum possible total score is 50, which is translated to a percentage. Higher scores indicate a greater degree of impairment. The NDI has been demonstrated to be a valid, had stable psychometric characteristics and accurate questionnaire for people suffering from neck pain
Quality of life (QoL) assessment — 6 weeks The SF-36 questionnaire will be used to assess QoL for all participants before and after the end of the study program. It is a self-administered questionnaire containing 36 items which takes about five minutes to complete. It measures health on eight multi-item dimensions, covering physical functioning, role limitation due to physical health, bodily pain, general health perception, vitality, social functioning, role limitation due to emotional problems and perceived mental health. Each domain contains number of items. The answers to each question are extrapolated to a standardized set of answers, and the results are transferred to a scale of 0-100, where 0 represents the worst state of health measured, and 100 represents the best state of health measured. It has good validity and reliability and can be used as a general questionnaire to assess quality of life.
