Cervical Radiculopathy: Symptoms, Causes, and How Physical Therapy Helps

What Is Cervical Radiculopathy?

Cervical radiculopathy is a condition in which a nerve root in the cervical spine (neck) becomes compressed or irritated, producing pain, numbness, tingling, or weakness that radiates from the neck into the shoulder, arm, or hand. Often called a pinched nerve in the neck, cervical radiculopathy affects approximately 85 out of every 100,000 people annually and is most common in adults between 40 and 60 years old. At Spectrum Therapeutics in Wayne, NJ, Dr. Rob Letizia, DPT has treated thousands of cervical radiculopathy patients over his 25-plus years of clinical practice using a targeted, one-on-one approach that resolves symptoms without surgery for the vast majority of patients.

Cervical radiculopathy is a neurological condition caused by compression or irritation of a spinal nerve root as it exits the cervical spine through the neural foramen. The compression can result from a herniated disc, bone spur (osteophyte), degenerative changes, or narrowing of the neural foramen. The affected nerve root becomes inflamed, producing symptoms that follow the specific distribution pattern of that nerve, which helps clinicians identify exactly which level of the spine is involved.

What Are the Symptoms of Cervical Radiculopathy?

The symptoms of cervical radiculopathy depend on which nerve root is affected. The cervical spine has 8 nerve roots (C1 through C8), and each supplies specific muscles and skin areas in the shoulder, arm, and hand. The most commonly affected levels are C6 and C7.

C5 Nerve Root Compression

Pain and weakness in the shoulder and upper arm, difficulty raising the arm, and decreased biceps reflex. Numbness may occur on the outer shoulder.

C6 Nerve Root Compression

Pain radiating from the neck through the biceps area into the thumb and index finger. Weakness in wrist extension and biceps. Decreased brachioradialis reflex. This is one of the most common levels affected.

C7 Nerve Root Compression

Pain radiating from the neck through the triceps area into the middle finger. Weakness in triceps, wrist flexion, and finger extension. Decreased triceps reflex. This is the most commonly affected level.

C8 Nerve Root Compression

Pain radiating into the ring and little fingers. Weakness in grip strength and fine motor control. Numbness on the inner forearm and hand.

Common symptoms across all levels include neck pain that worsens with certain head positions, pain that radiates down the arm following a specific nerve path, numbness or tingling in the shoulder, arm, or hand, weakness in specific muscles of the arm or hand, and symptoms that worsen with neck extension or rotation toward the affected side. Dr. Rob Letizia at Spectrum Therapeutics performs specific clinical tests during your evaluation to determine which nerve root is affected and the most effective treatment approach.

What Causes Cervical Radiculopathy?

Cervical Disc Herniation

A herniated disc in the cervical spine is the most common cause of cervical radiculopathy in younger patients (under 50). The soft inner material of the disc pushes through a tear in the outer ring and compresses the adjacent nerve root. This can occur from a sudden injury or develop gradually from disc degeneration.

Cervical Spondylosis (Degenerative Changes)

In patients over 50, degenerative changes including bone spurs, disc height loss, and spinal stenosis are the most common causes of nerve root compression. These changes develop gradually over years and may eventually narrow the neural foramen enough to compress the exiting nerve root.

Other Causes

Less common causes include trauma such as whiplash injuries, tumors, infections, and inflammatory conditions. These are ruled out during the evaluation process.

Can Physical Therapy Fix a Pinched Nerve in the Neck?

Physical therapy is the most effective non-surgical treatment for cervical radiculopathy. Research shows that 75 to 90 percent of cervical radiculopathy cases resolve with conservative treatment including physical therapy, without requiring surgery. The key is receiving skilled, targeted treatment from a clinician who understands cervical nerve compression and treats you one-on-one.

At Spectrum Therapeutics, Dr. Rob Letizia uses a combination of manual therapy techniques to decompress the affected nerve root, including cervical traction both manual and mechanical, joint mobilization to improve segmental mobility and reduce nerve compression, neural mobilization techniques to restore normal nerve gliding, The Letizia Method for cervical disc conditions combining specific manual therapy with directional preference exercises, and progressive strengthening of the deep cervical flexors and scapular stabilizers to support the cervical spine and prevent recurrence.

Most patients with cervical radiculopathy at Spectrum Therapeutics see significant improvement in their arm symptoms within 2 to 4 sessions of one-on-one treatment. The radiating pain, numbness, and tingling often improve before the neck pain itself, as the nerve root decompresses and inflammation decreases.

How Long Does Cervical Radiculopathy Take to Heal?

The healing timeline for cervical radiculopathy varies based on the cause and severity. Acute cervical radiculopathy from a new disc herniation often shows significant improvement within 4 to 6 weeks of physical therapy. Chronic cervical radiculopathy from degenerative changes may require 8 to 12 weeks of treatment. The natural history of cervical radiculopathy is generally favorable, meaning most cases improve over time, but physical therapy significantly accelerates the process and reduces the risk of recurrence.

Without treatment, cervical radiculopathy can persist for months and may lead to progressive weakness, chronic pain, and functional limitations. Early intervention with skilled physical therapy produces the best outcomes. At Spectrum Therapeutics in Wayne, NJ, same-day and next-day appointments are available so you do not have to wait weeks while your symptoms worsen.

What Is the Best Treatment for Cervical Radiculopathy?

Clinical practice guidelines recommend a stepped approach to cervical radiculopathy treatment starting with physical therapy as the first-line intervention. Physical therapy that includes manual therapy, targeted exercise, and patient education is supported by strong evidence for cervical radiculopathy. Cervical epidural steroid injections may be considered if physical therapy alone does not provide adequate relief. Surgery, specifically anterior cervical discectomy and fusion (ACDF), is reserved for patients who fail conservative treatment after 6 to 12 weeks or who have progressive neurological deficits.

Shockwave therapy may also benefit some cervical radiculopathy patients by reducing chronic muscle tension and trigger points in the neck and shoulder region that contribute to nerve irritation. Dr. Rob Letizia evaluates each patient individually to determine the optimal combination of treatments.

Do I Need Surgery for Cervical Radiculopathy?

Most patients with cervical radiculopathy do not need surgery. Surgery is typically recommended only when conservative treatment including physical therapy has failed after an adequate trial of 6 to 12 weeks, when there is progressive motor weakness indicating worsening nerve compression, when there is evidence of spinal cord compression (myelopathy), or when pain is severe and unresponsive to all conservative measures.

If surgery becomes necessary, physical therapy is essential both before and after the procedure to optimize outcomes. Pre-surgical physical therapy (prehabilitation) improves post-operative recovery, and post-surgical rehabilitation restores strength, mobility, and function. Dr. Rob Letizia at Spectrum Therapeutics manages both pre and post-surgical cervical spine patients one-on-one.

Frequently Asked Questions About Cervical Radiculopathy

Can cervical radiculopathy cause headaches?

Yes. Cervical radiculopathy, particularly at the upper cervical levels (C2-C3), can cause headaches that originate from the neck and radiate to the back of the head, temples, or behind the eyes. These are called cervicogenic headaches and respond well to physical therapy targeting the upper cervical spine.

Is it safe to exercise with cervical radiculopathy?

Yes, with appropriate guidance. Certain exercises can actually help decompress the nerve and reduce symptoms, while others may aggravate the condition. A physical therapist determines which exercises are safe and beneficial for your specific situation. Gentle cervical retraction exercises, nerve gliding, and scapular stabilization are typically well-tolerated and helpful.

How do I sleep with cervical radiculopathy?

Sleep on your back with a supportive cervical pillow that maintains the natural curve of your neck, or on your side with a pillow thick enough to keep your spine aligned. Avoid sleeping on your stomach. Some patients find relief by sleeping with the affected arm elevated on a pillow to reduce nerve tension. Dr. Rob Letizia provides specific sleep positioning guidance based on your symptoms.

Will my cervical radiculopathy come back?

Cervical radiculopathy can recur, particularly if the underlying degenerative changes continue to progress. Physical therapy reduces the risk of recurrence by strengthening the muscles that support and stabilize the cervical spine, improving posture, and teaching self-management strategies. Patients who complete their full course of physical therapy and maintain their exercise program have lower recurrence rates.

What is the difference between cervical radiculopathy and cervical myelopathy?

Cervical radiculopathy involves compression of a single nerve root producing symptoms in one arm. Cervical myelopathy involves compression of the spinal cord itself and produces symptoms in both arms and both legs, including difficulty with fine motor tasks, gait instability, and bowel or bladder changes. Myelopathy is a more serious condition that often requires surgical intervention. Your physical therapist screens for signs of myelopathy at every evaluation.

Does insurance cover physical therapy for cervical radiculopathy?

Yes. Physical therapy for cervical radiculopathy is medically necessary and covered by virtually all insurance plans. Spectrum Therapeutics accepts Medicare, Horizon BCBS, Aetna, Cigna, UnitedHealthcare, and most major plans. No referral is required in New Jersey.
