This study will be conducted to: * Investigate the relationship between neck pain severity and bilateral gait symmetry in patients with cervical radiculopathy. * Investigate the relationship between deep neck flexors strength and gait symmetry in patients with cervical radiculopathy. * Investigate the relationship between upper limb muscles strength and bilateral gait symmetry in patients with cervical radiculopathy. * Determine factors predicting bilateral gait asymmetry in patients with cervical radiculopathy.
Cervical pain and upper limb radiculopathy put a huge burden on patients due to its sensory dysfunction manifestations and also affect its motor capabilities, specifically the gait performance, understanding how cervical and upper limb pain or/and weakness contribute to gait disturbance can guide us to make a better assessment and rehabilitation program for each patient individually. Gait symmetry is considered as a very important factor to guarantee a safe and effective walking and for the daily movement, recent studies found out that patients with chronic neck pain and radiculopathy have slower gait pattern and increase of gait asymmetry which can impair balance and functional mobility. Also, the alteration of the cervical and upper limb muscle strength can impair the whole-body dynamic stability and increase the gait asymmetry. Altered gait symmetry has been linked to increase the risk of falling and disability, so getting to know some of its contributors and treat it (such as specific muscle strengthening) can enhance patient mobility and reduce fall morbidity. To our best knowledge, there are no studies about the relationship between neck pain, muscle strength in patients with cervical radiculopathy, so this study will be conducted to investigate the gait asymmetry and its relationship with neck pain and muscles strength in patients with cervical radiculopathy.

Pain Assessment
The level of upper limb and neck pain will be captured separately with the Numeric Pain Rating Scale (NPRS). Using an 11-point scale, ranging from 0 (no pain) to 10 (worst pain imaginable), participants will be asked to answer the following question: "On a scale of 0 to 10, where 0 = no pain and 10 = worst pain, evaluate the intensity of your neck pain at this moment ". The same question will be asked for the upper limb. The NPRS is frequently used in clinical studies in association with the neck disability index.
Time frame: 1 day
Assessment of function and disability
Arabic version of Neck Disability Index (NDI) will be used to assess disability and function limitation caused by neck pain. It has demonstrated excellent internal consistency (Cronbach's alpha between 0.88 and 0.94) and test-retest reliability (ICC = 0.90-0.98). It includes 10 items, each scored on a 0-5 scale, about: personal care, lifting, reading, concentration, work, driving, and sleeping. The total maximum score is 50 and categorize disability from none to complete , The Arabic version of NDI is a strong valid method for assessing self-rated disability in patients with neck pain with excellent "test-retest" reliability. Based on the total score (out of 50), disability will be categorized as: 0-4 = no disability, 5-14 = mild, 15-24 = moderate, 25-34 = severe, \>34 = complete disability
Time frame: 1 day
strength of deep neck flexors
Pressure Biofeedback Unit (PBU) will be used to assess deep neck flexor strength. From a supine position and both knees bent in flexion and arms relaxed at the sides. The PBU cuff will be placed under the suboccipital region of his neck and then inflated to a baseline pressure of 20 mmHg. Patients will be instructed to perform a gentle chin in motion without lifting their heads off the surface or activating superficial muscles. The patient will then be guided to increase the pressure in 2 mmHg stages to a maximum of 30 mmHg, and to hold each stage for 10 seconds taking no rest intervals between his attempts. The maximum pressure which he achieves and holds correctly without compensatory strategies will be recorded. 3 trials will be conducted.

Upper limb strength assessment
Upper limb strength will be measured using a hand-held dynamometer. Participants will be seated in upright posture, with their shoulders adducted and neutrally rotated, and their elbows will be flexed at 90 degrees, their forearms will be placed in a neutral position, and their wrists extended between 0-30 degrees, testing protocol. Each participant will be instructed to grip the dynamometer with his maximum effort for about 3-5 seconds. The participant will receive consistent verbal encouragement from the assessor to ensure maximal voluntary contraction is achieved. Each participant will perform 3 trials on their affected side, with a one-minute rest between his attempts to avoid muscle fatigue.
Time frame: 1 day
Cadence
The Tekscan Strideway™ system will be used to objectively assess spatiotemporal gait parameters for all participants with cervical radiculopathy. Cadence is the number of steps taken per minute (steps/minutes).
Time frame: 1 day
Gait Velocity
The Tekscan Strideway™ system will be used to objectively assess spatiotemporal gait parameters for all participants with cervical radiculopathy. Gait Velocity is the average walking speed, calculated as Gait Distance divided by Gait Time (centimeter/second).
Time frame: 1 day
Symmetry Index (SI)
The Tekscan Strideway™ system will be used to objectively assess spatiotemporal gait parameters for all participants with cervical radiculopathy. Symmetry Index (SI) is a calculated percentage representing the degree of asymmetry between the right and left sides for any given gait parameter (%). Formula used: SI = \[(Right - Left) / 0.5 \* (Right + Left)\] \* 100.
Time frame: 1 day
Step Time symmetry index
The Tekscan Strideway™ system will be used to objectively assess spatiotemporal gait parameters for all participants with cervical radiculopathy. Step time is the percentage of asymmetry between the right step time and the left step time (%).
Time frame: 1 day
Step Length symmetry index
The Tekscan Strideway™ system will be used to objectively assess spatiotemporal gait parameters for all participants with cervical radiculopathy. Step Length is a percentage of asymmetry between the right step length and the left step length (%).
Time frame: 1 day
Single Support Time symmetry index
The Tekscan Strideway™ system will be used to objectively assess spatiotemporal gait parameters for all participants with cervical radiculopathy. Single Support Time is the percentage of asymmetry between the average right single support time and the average left single support time (%).
Time frame: 1 day
Double Support Time symmetry index
The Tekscan Strideway™ system will be used to objectively assess spatiotemporal gait parameters for all participants with cervical radiculopathy. Double Support Time is the percentage of asymmetry between the average right total double support time and the average left total double support time (%).
