This study is conducted to investigate:

1. The efficiency of combination of KT and proprioceptive exercises on neck proprioception in patients with CR.
2. The efficiency of combination of KT and proprioceptive exercises on neck pain, neck function and neuropathic pain in patients with CR.

Cervical radiculopathy is a common neck disorder that reduces function, productivity, and quality of life. Cervical radiculopathy impacts cervical nerves roots, with the highest prevalence of C6 and C7 nerve roots. The incidence of cervical radiculopathy affects roughly 107.3 out of 100,000 males and 63.5 out of 100, 000 females. This incidence in the fifth decade of life increases up to 203 per 100 000. The etiology of cervical radiculopathy is commonly attributed to mechanical compression or chemical irritation of the cervical nerve roots. The most contributing factor is probably related to disc herniation. Other problems that decrease the intervertebral foramen include trauma, infection, and tumors .

Inflammation or impingement of these nerve roots trigger pain receptors located in soft tissues and joints of the cervical spine, resulting in sensory changes such as tingling and motor loss in dermatomal and myotomal distribution depending on affected nerve root. Patients often complain of combination of neck pain and radiating pain in the arm. The impairments in cervical proprioceptive inputs have been attributed to neck pain and altered input from cervical afferents, particularly muscle spindle, Muscle spindles are accepted as being the primary cervical receptors responsible for position sense and are coupled to supplementary afferent input from the cutaneous and joint receptors.

Conservative treatment approaches described to date have included pharmacology, advice to remain active, manual therapy, exercise, acupuncture, traction, collars, epidural injection in addition to kinesio tape (KT). Manual therapy can include muscle energy techniques, high velocity manipulation or low velocity mobilization of the cervical and/or thoracic spine, soft-tissue mobilization, and neural mobilization techniques.

Previously, in different musculoskeletal problems, KT combined with conventional rehabilitation has been shown to produce greater improvements in pain, range of motion, and functional outcomes compared to the rehabilitation program alone in cervical spondylosis and low back pain. It was reported that in comparison to sham application, 2 weeks of kinesio tape (KT) application practiced in addition to a home exercise program was effective on pain and tenderness in individuals with cervical myofascial pain. Additionally, KT was effective on cervical proprioception 24 hours after its application in chronic neck pain patients. KT is believed to stimulate cutaneous and muscle mechanoreceptors, which enhances sensorimotor control and proprioceptive feedback, thereby assisting in movement coordination and reducing discomfort in ankle proprioception and different musculoskeletal conditions.

To date, there is only one study that specifically investigated the effect of KT on patient with CR. KT taping method along with manual therapy treatment, cervical stabilization exercises was effective in treating patients with cervical radiculopathy.

Exercise therapy is effective in the management of CR, which can relieve pain and improve cervical function. Many exercises used in management of CR like stretching exercises for tighten muscles. Neural mobilization techniques (e.g., Upper Limb Tension Test 1 sliding and gliding) to restore neural dynamics and decrease radicular pain .

Proprioceptive training can lead to significant improvements in proprioceptive and motor function across a range of healthy and clinical populations. General neck-shoulder ROM and cervical proprioceptive exercises including eye-head coordination exercise can be effective in improving neck proprioceptive acuity, pain, and disability in chronic nonspecific neck pain patients.

A study was conducted to investigate the effect of proprioceptive training on patients with CR, including cervical position sense training, head-eye coordination exercises, and postural control exercises. The authors reported a significant improvement in cervical ROM and marked reduction in pain intensity (VAS) in the proprioceptive training group compared to conventional physical therapy group.

The effectiveness of deep cervical flexors strengthening exercises has demonstrated positive outcomes in terms of decrease in neck pain and disability, improvement in sitting posture, enhanced neuromuscular control of the cervical flexors in patients with chronic neck pain, and improved proprioceptive acuity of the neck, indicating that proprioception can be enhanced with specific exercise.

Strengthening, stabilization, and eye-head coordination exercises directed toward the deep cervical flexors, scapular stabilizers, and oculomotor-cervical control has been shown to enhance cervical spine stability and improve proprioceptive function in neck pain.

To the best of the author's knowledge, no previous study combined proprioceptive exercises and Kinesio tape in management of CR. Consequently, this study will be conducted to examine the effect of this combination on proprioceptive in patients with CR.
