Patients with neck pain are the second largest group after patients with
Low back pain that attended to physical therapy. Clinical experience and research indicated that significant sensorimotor cervical proprioceptive disturbances might be an important factor in the maintenance, recurrence, or progression of various symptoms in some patients with neck pain. There is evidence that specific treatment programs that have trained cervical joint position sense, eye-neck coordination, and gaze stability result improvements not only in sensorimotor impairments but also in neck pain and disability. The aim of this study is comparing the effects of traditional exercises and sensory-motor training exercises on joint position sense, kinematics, inter segmental coordination, dynamic balance, pain and disability in people with chronic non-specific neck Pain. In this study forty patients with non-specific neck pain are randomly allocated to either a control group or specific exercise group. Patients in control group receive TENS, stretch and training deep flexors and extensors muscles and those in second group receive control group exercises plus sensory-motor exercises. The intervention period was 12 session. Also, in this study both the investigator and the participant are blind to the nature of the treatment. Assessments will performed pre and post treatment. Outcome measures are: joint position error, kinematic items, dynamic balance, pain (Visual Analogue Scales) and dis ability (Neck Disability Index).
