Overview

Cervical radiculopathy was first described in 1943 by researchers named Semmes and Murphy, years later than lumbosacral radiculopathy. It is a neurological condition caused by dysfunction in the cervical spinal nerves, nerve roots, or both. This compression occurs as a result of disc herniation, spondylosis, trauma, spinal tumors, etc. As the first symptom, it manifests as pain. When pain radiates from the neck to the shoulder and arm and is accompanied by sensory complaints and motor weakness, cervical radiculopathy should be suspected. It is a significant cause of morbidity and disability in both men and women, and it occurs in middle age. As a result, clinicians must quickly diagnose and determine the best treatment method. The majority of the information in the literature on the incidence of cervical radiculopathy is based on the findings of a large population-based study conducted between 1976 and 1990 by the Mayo Clinic in Rochester, Minnesota. The incidence rate of cervical radiculopathy was reported to be 83.2 per 100,000 per year in this study, which included 561 cases. The primary goals of treatment are to alleviate pain, restore neurological function, and prevent a recurrence. According to the literature, cervical radiculopathy recurs at a rate of 31.7%, and 26% of them go to surgery. Treatment options vary depending on whether the symptoms are acute or chronic and their severity. In the treatment of cervical radiculopathy, either conservative (non-operative) or surgical treatments are used. In patients with chronic neck pain with or without radiculopathy, a cervical epidural steroid injection is one of the most frequently used interventional therapeutic options. Chronic neck pain or radicular pain caused by disc herniation, spinal stenosis, or discogenic pain can also be treated with cervical epidural injections. Cervical stability training is an exercise program that is used to strengthen the cervical spine, relieve pain, and improve functionality. Changes in dynamic scapula stabilization are observed in patients with chronic neck pain. The scapula connects the neck and shoulder, so it plays an important role in stabilizing the neck and shoulder complex. Because of the interaction between the neck and the scapula, scapular stability becomes more important in these patients.

Many studies in the literature separately investigate the effectiveness of Cervical Interlaminar Epidural Steroid Injection (CIESI) in radiculopathy due to cervical disc herniation or the effectiveness of stabilization exercises and physical therapy modalities in these patients. However, there have been no studies on the effectiveness of post-injection exercise training as far as we are aware. Our study aims to investigate the benefit of stabilization exercises after interlaminar epidural steroid injection in patients with radiculopathy caused by cervical disc herniation, add a new study to the literature, and guide future research.

Interventions

Cervical Interlaminar Epidural Steroid InjectionPROCEDURE

Fluoroscopy-guided cervical interlaminar epidural steroid injection will be administered to patients with chronic neck pain due to cervical disc herniation. The injection area is cleaned 3 times with an antiseptic solution and covered with a sterile cloth. Local anesthesia with 2 ccs 3% prilocaine will be applied to the skin and subcutaneous tissues in the area of interest. Under fluoroscopy guidance, the needle is advanced into the C7-T1 intervertebral disc level. With the help of the loss of resistance technique, it is understood that the needle is in the epidural space, and second control is provided by administering contrast material. After the confirmation of needle place is done, a mixture of 12 mg dexamethasone, 1 cc 2% lidocaine, 1 cc saline is injected. The patient is taken to the restroom after the procedure and followed up for any complications.

Neck Stabilization ExercisesOTHER

The physiotherapist will design an exercise protocol for neck stabilization. Each exercise will be applied three days a week throughout a 4-week program, accompanied by a physiotherapist, and will begin with 7 to 10 repetitions at first, increasing to 10 to 15 repetitions in the following weeks, taking into account the patient's condition. After the physiotherapist-assisted exercises are completed, the protocol will continue as home-based exercises until the assessments are completed.

Neck and Scapular Stabilization ExercisesOTHER

The physiotherapist will design an exercise protocol for neck and scapular stabilization. Each exercise will be applied three days a week throughout a 4-week program, accompanied by a physiotherapist, and will begin with 7 to 10 repetitions at first, increasing to 10 to 15 repetitions in the following weeks, taking into account the patient's condition. After the physiotherapist-assisted exercises are completed, the protocol will continue as home-based exercises until the assessments are completed.

Outcomes

Primary Outcomes

Change of pain severity from baseline to each checkpoints

The numerical rating scale (NRS) is widely used in research and clinical settings to represent pain intensity. NRS is defined as 0 for the absence of pain and 10 as the worst possible pain. The NRS is moderately reliable and has a clinically important difference (CID) value of 1.0.

Time frame: from pre-interventional time to post-interventional 1st hour, 1st month, 3rd month

Secondary Outcomes

Change of functionality from baseline to each checkpoints

The Neck Disability Index (NDI) is a validated 10-item questionnaire that measures a patient's self-reported disability due to neck pain. The score ranges from 0 (no disability) to 100 (completely disabled). The minimum detectable change (MDC) for patients with cervical radiculopathy is 10 points, and the clinically important difference (CID) is 14 points.

Time frame: from pre-interventional time to post-interventional 1st month, 3rd month

Change of life quality from baseline to each checkpoints

Short Form-12 (SF-12) is a scale that was developed in 1994 to evaluate the quality of life for the last four weeks without focusing on a specific age and disease group. It consists of 12 questions, all selected from the SF-36 Health Questionnaire. SF-12 consists of physical functionality, physical role, pain, general health, emotional role, mental health, social functionality, and vitality sub-components.
