Interlaminar epidural steroid injection for arm position sense in chronic cervical radiculopathy.

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective interventional study enrolls adults with unilateral chronic cervical radiculopathy due to cervical disc herniation and measures upper extremity proprioception before and after a unilateral interlaminar epidural steroid injection (ILESI). Proprioception will be quantified using the PRO-Reach joint position sense test across multiple directions, and clinical outcomes will include neuropathic pain scores, pain intensity, disability indices, hand-grip strength, and health-related quality of life. Participants will undergo baseline testing, receive a single ILESI, and be reassessed at defined follow-up intervals to track changes in proprioception and clinical metrics. The study is conducted at Marmara University Pendik Training and Research Hospital.

Why it matters

* Presence of unilateral cervical radicular pain lasting at least 3 months
* MRI of the cervical spine within the last 12 months demonstrating at least one cervical disc herniation consistent with the patient's symptoms
* Diagnosed with chronic cervical radiculopathy based on history, physical examination, and clinical evaluation
* Ability to read and write (literacy)
* Willingness to participate and ability to provide written informed consent

Exclusion Criteria:

Participants will be excluded for any of the following:

* Cervical physical therapy or cervical spinal injection performed within the past 6 months
* Symptoms or diagnosis of upper extremity entrapment neuropathy
* Documented vitamin B12 deficiency or vitamin D deficiency on laboratory results within the past year
* History of cervical spine surgery or significant cervical trauma
* Bilateral cervical radicular pain
* Cervical spinal stenosis
* History of upper extremity surgery or significant upper extremity trauma
* Cognitive impairment, major psychiatric disorder, intellectual disability, or history of significant neurological disease
* Diagnosis of polyneuropathy
* Diagnosis of Diabetes Mellitus
* Diagnosis of fibromyalgia
* Current use of medications that may impair proprioception or have sedative effects (e.g., gabapentinoids, antidepressants, muscle relaxants)
* Active local or systemic infection
* Coagulopathy or bleeding diathesis
* Known allergy to any components of the planned injection (triamcinolone, lidocaine, saline, contrast medium)
* Pregnancy
* Inability or unwillingness to provide informed consent
* Illiteracy (unable to read or write)

Withdrawal Criteria
