Chiropractic Rehabilitation Strategies for Shoulder Pain

Explore effective chiropractic rehabilitation techniques to relieve discomfort and enhance mobility from shoulder pain.’

Abstract

Shoulder pain is a common, often debilitating condition that can significantly affect quality of life, daily activities, and athletic performance. While many associate shoulder problems with muscle tears or joint instability, a frequently overlooked cause is suprascapular neuropathy, a nerve compression syndrome that can lead to persistent pain, weakness, and muscle atrophy. This educational post explores suprascapular neuropathy, from its underlying anatomy and pathophysiology to its clinical presentation and diagnosis. We will review the latest findings from leading researchers and present a modern, evidence-based approach to understanding this condition. As a clinician with a diverse background spanning chiropractic (DC), advanced practice nursing (APRN, FNP-BC), and functional medicine (CFMP, IFMCP), I will guide you through this complex topic from a first-person perspective. We will examine the case of an 18-year-old weightlifter presenting with classic symptoms, using it as a practical framework to discuss diagnostic procedures like a targeted suprascapular nerve block. This post will also highlight the power of a multidisciplinary approach, showing how our clinic, Injury Medical Clinic PA, integrates my expertise with the medical oversight of our Medical Director, Dr. Maria Guadalupe Cardenas, MD. We will show how integrative chiropractic care, combined with internal medicine, functional medicine, and rehabilitation, offers a comprehensive, personalized pathway to recovery for patients with this and other complex musculoskeletal conditions.

Introducing Our Integrative and Multidisciplinary Clinical Model

At Injury Medical Clinic PA, also known as Mission Plaza Injury Medical Clinic, in the vibrant community of El Paso, Texas, we have cultivated a unique healthcare environment grounded in collaboration and a patient-centered philosophy. My journey in healthcare has led me to earn a diverse set of credentials, including a Doctor of Chiropractic (DC), Advanced Practice Registered Nurse (APRN) certification with Family Nurse Practitioner Board Certification (FNP-BC), and advanced certifications in Functional Medicine (CFMP, IFMCP), among others. This multifaceted training allows me to view patient health through several lenses—structural, neurological, biomechanical, and metabolic.

However, our practice’s true strength lies in our multidisciplinary, team-based model. I am honored to work alongside Dr. Maria Guadalupe Cardenas, MD, our esteemed Medical Director and Collaborative Physician. Dr. Cardenas is a Board-Certified Internist with an impressive career spanning over 40 years. Her extensive experience and deep understanding of internal medicine provide essential medical oversight and diagnostic acumen that enrich our patient care. Her Texas Medical License (#J2933) and NPI number (#1164426749) represent a foundation of established medical practice and credibility.

This collaborative structure is common in leading-edge integrative and injury care clinics. It allows us to seamlessly blend chiropractic principles—focused on spinal alignment, nervous system function, and biomechanics—with the robust diagnostic and treatment framework of allopathic medicine. Dr. Cardenas’s role is pivotal; she reviews complex cases, provides medical direction, and ensures that our treatment plans are safe, effective, and medically sound. Together, we integrate a spectrum of services, including:

• Chiropractic Care: Manual adjustments, spinal decompression, and soft tissue therapies to restore proper joint function and nerve integrity.
• Medical Oversight (Internal Medicine): Comprehensive diagnostics, management of underlying medical conditions, and pharmacological interventions when necessary.
• Functional Medicine: Investigating root causes of dysfunction by examining genetics, lifestyle, and environmental factors.
• Personal Injury and Rehabilitation: Specialized protocols for accident-related injuries, focusing on functional recovery and long-term stability.
• Physical Therapy and Corrective Exercises: Tailored programs to strengthen weakened muscles, improve mobility, and prevent re-injury.

This model lets us offer patients the best of multiple worlds, creating a holistic treatment plan that addresses the individual as a whole, not just a collection of symptoms. The case of suprascapular neuropathy we will discuss is a perfect example of how this integrated approach provides superior outcomes.

A Clinical Encounter: The Case of the Young Weightlifter

On September 2, 2026, an 18-year-old gentleman walked into my clinic, presenting a clinical puzzle that is becoming increasingly common, especially among young athletes. He described a five-month history of a vague, yet persistent, pain in his left shoulder. What began as a minor annoyance had insidiously progressed, growing in intensity and beginning to interfere significantly with his life. He reported that the pain was particularly bothersome at night, often disrupting his sleep—a classic sign of an inflammatory or compressive neurological issue.

As a dedicated weightlifter for the past seven or eight years, he considered the gym his sanctuary. However, it had recently become a source of frustration. He noted a marked decrease in his ability to perform key movements, specifically abduction (lifting his arm out to the side) and external rotation (rotating his arm outward, as if preparing to throw a ball). This weakness was not just a subjective feeling; it was a measurable deficit that was stalling his progress and causing him concern.

The Physical Examination: Uncovering the Telltale Signs

A thorough physical examination is the cornerstone of any accurate diagnosis. As I assessed his shoulders, the asymmetry was immediately apparent. On the left side, the side of his pain and weakness, there was visible atrophy, or wasting, of two key rotator cuff muscles:

1. The Infraspinatus Muscle: Located on the lower part of the shoulder blade, this muscle primarily drives external rotation. The visible hollowing or depression in this area on his left side, compared with the robust, well-defined muscle on his right, was a significant finding.
2. The Supraspinatus Muscle: Situated in the fossa (a shallow depression) above the spine of the scapula, this muscle is crucial for initiating the first 15-30 degrees of arm abduction. Atrophy here was also noticeable, contributing to his difficulty with lifting his arm.

These findings—progressive, insidious-onset pain; weakness in abduction and external rotation; and visible atrophy of the supraspinatus and infraspinatus muscles—form the classic triad pointing to a specific diagnosis: suprascapular neuropathy.

This is not a simple muscle strain or tendonitis. This is a compression neuropathy in which the suprascapular nerve is squeezed or entrapped as it travels through a narrow anatomical passageway.

Anatomy of the Suprascapular Nerve: A Journey Through Tight Spaces

To understand suprascapular neuropathy, we must first appreciate the suprascapular nerve’s intricate journey. This nerve is a critical component of the brachial plexus, the complex network of nerves originating from the neck (specifically, from the C5 and C6 spinal nerve roots) that supplies the shoulder, arm, and hand.

The Path of the Nerve

The suprascapular nerve embarks on a precise and winding path:

1. Origin: It branches off the superior trunk of the brachial plexus in the posterior triangle of the neck.
2. The Suprascapular Notch: The nerve then travels posteriorly, heading toward the scapula (shoulder blade). Its first major hurdle is the suprascapular notch. This is a small, U-shaped or V-shaped indentation on the superior border of the scapula. The superior transverse scapular ligament stretches across the top of this notch, converting it into a foramen, or tunnel. The suprascapular nerve passes through this tunnel, underneath the ligament. In contrast, the suprascapular artery and vein, which travel alongside the nerve, typically pass over the ligament. This anatomical arrangement makes the nerve particularly vulnerable to compression at this site.
3. The Supraspinatus Fossa: After successfully navigating the notch, the nerve enters the supraspinatus fossa. Here, it gives off its first motor branches, providing the electrical signals that power the supraspinatus muscle. It also sends sensory branches to the acromioclavicular (AC) and glenohumeral (shoulder) joints, which is why compression can cause deep, aching joint pain.
4. The Spinoglenoid Notch: The nerve then continues its journey, wrapping around the lateral edge of the scapular spine to reach the spinoglenoid notch. This is the second potential site of entrapment. This notch is the space between the spine of the scapula and the glenoid rim (the “socket” of the shoulder joint). As the nerve passes through this second notch, it enters the infraspinatus fossa.
5. Final Destination: In the infraspinatus fossa, the nerve terminates by innervating the infraspinatus muscle.

Why This Anatomy Matters

Understanding this pathway is crucial because the location of the compression determines the clinical presentation:

• Compression at the Suprascapular Notch (Proximal): If the nerve is compressed at its first hurdle, the suprascapular notch, the electrical signals to both the supraspinatus and infraspinatus muscles will be disrupted. This results in weakness and atrophy in both muscles, leading to deficits in both abduction and external rotation. This is what I suspected in our 18-year-old patient.
• Compression at the Spinoglenoid Notch (Distal): If the compression occurs further down the line, at the spinoglenoid notch, the nerve supply to the supraspinatus muscle has already been delivered. Therefore, only the infraspinatus muscle will be affected. This causes isolated weakness in external rotation and infraspinatus atrophy, while abduction strength remains intact. This is often seen in overhead athletes (e.g., volleyball players, baseball pitchers) due to repetitive microtrauma or sometimes due to a space-occupying lesion like a paralabral cyst.

The Causes of Suprascapular Nerve Entrapment

What causes this critical nerve to become compressed? Causes can be broadly categorized as dynamic, traumatic, or due to space-occupying lesions.

• Repetitive Microtrauma: This is a very common cause, particularly in athletes. For our weightlifting patient, years of heavy lifting, especially movements like overhead presses, bench presses, and lat pulldowns, can create dynamic compression. Repetitive overhead motions can cause the superior transverse scapular ligament to hypertrophy (thicken) or ossify (turn to bone), narrowing the suprascapular notch. This is a classic overuse injury.
• Acute Trauma: A direct blow to the shoulder or a fracture of the scapula can directly injure the nerve or alter the anatomy of the notch, leading to compression. A hard fall onto the shoulder could also cause traction or stretching of the nerve, resulting in injury.
• Anatomical Variations: Not everyone’s anatomy is the same. Some individuals are born with a very narrow or V-shaped suprascapular notch, predisposing them to compression. Variations in the transverse scapular ligament can also contribute.
• Space-Occupying Lesions: Anything that takes up space near the nerve’s path can cause compression. This includes:

• • Ganglion Cysts (or Paralabral Cysts): These are benign, fluid-filled sacs that can arise from the shoulder joint capsule, often in the context of a labral tear. If a cyst forms near the spinoglenoid notch, it is a very common cause of isolated infraspinatus atrophy.
  • Tumors: Although rare, benign and malignant tumors can grow near the nerve.
  • Lipomas: Benign fatty tumors can also cause compression.

• Shoulder Instability and Rotator Cuff Tears: Massive rotator cuff tears can cause the humeral head to migrate superiorly, altering shoulder biomechanics and placing traction on the nerve. Similarly, chronic instability can lead to abnormal movement patterns that stress the nerve over time.

Given my patient’s history of long-term weightlifting, repetitive microtrauma leading to dynamic compression at the suprascapular notch was my leading hypothesis. The insidious onset and progressive nature of his symptoms fit this picture perfectly.

Diagnostic Strategy: The Suprascapular Nerve Block

While the clinical picture was highly suggestive of suprascapular neuropathy, confirming the diagnosis and providing therapeutic relief is the next critical step. This is where a diagnostic and therapeutic suprascapular nerve block comes into play. This procedure involves injecting a local anesthetic, often combined with a corticosteroid, precisely at the site of suspected nerve compression.

The Dual Purpose of the Injection

1. Diagnostic: If the patient’s pain is significantly relieved, even temporarily, by the numbing effect of the local anesthetic (like lidocaine), it provides strong evidence that the suprascapular nerve is indeed the source of the pain. This confirms our clinical suspicion.
2. Therapeutic: The corticosteroid in the injection is a powerful anti-inflammatory agent. By delivering it directly to the site of nerve entrapment, we can reduce inflammation and swelling around the nerve. This can “decompress” the nerve, alleviate the compression, and provide longer-lasting pain relief, sometimes for weeks or even months. This anti-inflammatory effect also creates a crucial window of opportunity for effective rehabilitation.

Landmark-Guided Technique: A Precise Anatomical Approach

While ultrasound guidance is an excellent modern technique for this procedure, a well-executed landmark-guided injection, based on a deep understanding of surface anatomy, is also highly effective and has been a mainstay of clinical practice for decades. The goal is to precisely locate the suprascapular notch, which lies deep to the supraspinatus muscle.

Here is the step-by-step process I followed with our patient, a meticulous method designed for accuracy and patient safety:

Step 1: Identifying Key Bony Landmarks

First, palpate and mark the key bony structures of the shoulder girdle. This creates a reliable map to guide the needle.

• The Coracoid Process: I began by feeling for this hook-like bony prominence on the front of the shoulder. It’s located just medial to the head of the humerus and inferior to the clavicle. I asked the patient, “Does that hurt a little bit?” to confirm the pressure point. Once located, I made a small mark with a pen.
• The Spine of the Scapula: This is the prominent bony ridge that runs horizontally across the back of the shoulder blade. It’s easily palpable. I marked its course from the medial border of the scapula to its lateral tip.
• The Acromion: This is the bony “roof” of the shoulder, the lateral termination of the scapular spine. I marked the acromion’s tip.

Step 2: Mapping the Injection Point

With these primary landmarks established, the next step is to use them to pinpoint the suprascapular notch.

• First, I identified the midpoint of the line running along the spine of the scapula, between its medial origin and the tip of the acromion. I placed a mark here.
• Next, I envisioned and drew a line connecting this midpoint on the scapular spine to the coracoid process mark on the front of the shoulder.
• The injection point is the midpoint of this. Based on these anatomical relationships, this point places the needle tip directly over the supraspinatus fossa and, more importantly, very close to the underlying suprascapular notch.

Step 3: Preparing for the Injection

Safety and sterility are paramount.

• I used the retracted tip of a ballpoint pen to make a firm indentation at the precise injection site. This mark will remain visible even after I cleaned the skin.
• I thoroughly prepped the skin, first with an alcohol swab to remove the pen marks and degrease the skin.
• I then used a Betadine (povidone-iodine) swab, an antiseptic solution that kills germs on the skin surface to prevent infection.

Step 4: The Injection Cocktail

The medication choice is tailored to the procedure’s dual goals. For this patient, I prepared a syringe with:

• 1 mL of 1% Lidocaine with Epinephrine: Lidocaine is the local anesthetic that provides rapid numbing for diagnostic feedback. Epinephrine is a vasoconstrictor; it narrows the blood vessels in the area, which serves two purposes: it reduces bleeding and keeps the lidocaine localized longer, prolonging its anesthetic effect.
• 1 mL of a Corticosteroid Solution: This is the therapeutic anti-inflammatory agent. We use this to reduce the swelling and inflammation around the compressed nerve.
• The Needle: I used a one-inch, 25-gauge needle. The 25-gauge needle is relatively fine to minimize discomfort, and the one-inch length is sufficient to reach the target depth in a patient with this body habitus.

Step 5: Performing the Injection

Patient comfort is a priority.

• To minimize the sharp sting of the needle poke, I used a vapocoolant spray (Pain Ease). I sprayed it directly on the injection site until the skin turned white, indicating it was sufficiently chilled and numb. I told him, “Here’s the free spray I was telling you about.” This simple step can dramatically improve the patient experience.
• With the skin numb, I asked, “Does that hurt at all?” He replied, “No,” which is the response we want.
• I then inserted the needle perpendicularly to the skin, advancing it straight down. The goal is to gently touch the bone at the floor of the supraspinatus fossa. This bony feedback confirms that the needle is at the correct depth and not in a dangerous location.
• Once I felt bone, I retracted the needle about 1 mm. This slight retraction pulls the needle tip off the periosteum (the sensitive lining of the bone) and places it within the soft tissue of the fossa, right where the nerve is located.
• Before injecting, I performed a critical safety check: aspiration. I pulled back on the plunger to ensure no blood returned into the syringe. This confirmed that the needle tip was not in a blood vessel, specifically the nearby suprascapular artery. Seeing no blood flash, I proceeded to slowly inject the 2 mL solution, bathing the area around the nerve.

Step 6: Post-Injection Care and Immediate Mobilization

The procedure is quick, but the moments immediately following are important.

• I removed the needle and placed a simple adhesive bandage over the site.
• I immediately checked in with the patient: “Did that hurt?” His response, “No,” confirmed the local anesthetic and vapocoolant were effective.
• To help disperse the medication throughout the target area and prevent it from pooling in one spot, I instructed him, “Go ahead and take your other hand and rub this in… kind of give firm fingertips right there, and kind of firmly rub in.”
• Next, and perhaps most importantly, I had him immediately begin moving the arm through the very motions that were weak and painful. This is not just for assessment; it’s also a therapeutic maneuver. By activating the muscles innervated by the suprascapular nerve, we help “work ” the medication into the tissues.

• Abduction: “Let’s go ahead and bring your arm up like that, and down… do that a couple times, and do it a little faster.” The supraspinatus primarily initiates this movement. As I observed, “you can see he’s got quite a bit of deltoid that kicks in here,” indicating some compensatory muscle activation, which is common.
• External Rotation: “And now let’s do external rotation, rotate it out like that, back and forth a few times.” This directly engages the infraspinatus muscle.

By having him perform these movements immediately, we not only spread the medication but also get an instant diagnostic confirmation. If he can perform these movements with less pain and more ease right after the injection, it’s a positive sign.

The Role of Integrative Chiropractic Care in Recovery

The suprascapular nerve block is a powerful tool for diagnosis and initial relief, but it rarely cures the issue on its own. The injection reduces inflammation and pain, creating a vital “window of opportunity.” This is where a comprehensive, integrative approach, particularly one incorporating chiropractic care, becomes essential for achieving long-term recovery and preventing recurrence.

As a chiropractor, my focus extends beyond the site of pain to the entire kinetic chain and the nervous system that controls it. Suprascapular neuropathy does not occur in a vacuum. It often results from, or is exacerbated by, underlying biomechanical dysfunction.

1. Addressing Cervical Spine and Brachial Plexus Health

The suprascapular nerve originates from the C5 and C6 nerve roots in the cervical spine. Any neck dysfunction can affect the health of the entire brachial plexus.

• Cervical Spine Adjustments: I would perform a thorough assessment of the patient’s cervical spine. Misalignments, or subluxations, in the C5/C6 vertebrae can irritate nerve roots (a “double crush” phenomenon), making the peripheral nerve more susceptible to compression downstream at the shoulder. Precise, gentle chiropractic adjustments can restore proper motion to these segments, reduce nerve irritation at the root level, and improve the overall neurological tone of the brachial plexus.
• Neural Mobilization: I would use specific nerve gliding, or “flossing,” techniques for the brachial plexus. These gentle, controlled movements mobilize the nerve along its entire path, break up minor adhesions, and improve its ability to slide and glide freely through the anatomical tunnels. This can be taught to the patient as a home exercise.

2. Restoring Scapular Biomechanics (Scapulothoracic Rhythm)

The scapula is the foundation for shoulder movement. Abnormal scapular movement, known as scapular dyskinesis, is a major contributor to shoulder pathologies, including suprascapular neuropathy. Constant, abnormal tugging and shearing forces from a poorly moving scapula can directly lead to nerve entrapment.

• Thoracic Spine Mobilization: A stiff, kyphotic (rounded) thoracic spine forces the scapula to sit in a protracted (forward-rounded) and downwardly rotated position. This poor starting position completely disrupts normal scapulohumeral rhythm. Chiropractic adjustments to the thoracic spine are crucial to restore extension and rotation, allowing the scapula to move freely on the ribcage.
• Soft Tissue Therapy: Muscles that control scapular movement are often imbalanced. In many individuals, especially those who sit for long periods or have forward-rounded posture, the pectoralis minor and levator scapulae muscles are tight and overactive. At the same time, the serratus anterior and lower trapezius are weak and inhibited. I would use techniques like Active Release Technique (ART), Graston Technique, or trigger point therapy to release the tight muscles.
• Chiropractic Rehabilitation: This bridges the gap between passive care and active recovery. We would prescribe specific corrective exercises to activate the weakened scapular stabilizers. Exercises like wall slides, serratus punches, and “Y-T-W-L” raises are fundamental to retraining proper muscle firing patterns and establishing a stable base for the shoulder joint.

3. Integrating Functional Medicine for Systemic Support

Chronic inflammation is a key driver of nerve compression syndromes. As a functional medicine practitioner, I would also look at systemic factors that could be contributing to my patient’s condition.

• Anti-Inflammatory Diet: I would counsel the patient on adopting a diet rich in anti-inflammatory foods (e.g., omega-3 fatty acids from fish, colorful fruits and vegetables, turmeric, ginger) and low in pro-inflammatory foods (e.g., processed sugar, refined carbohydrates, industrial seed oils). Reducing the body’s overall inflammatory burden can help calm the inflammation around the nerve.
• Targeted Supplementation: Based on a thorough history and possibly lab work, I might recommend supplements like high-dose Omega-3s, curcumin (the active compound in turmeric), Alpha-Lipoic Acid (an antioxidant that supports nerve health), or B-vitamins (especially B6 and B12), which are crucial for nervous system function.

The Synergy of a Multidisciplinary Team

This is where the collaboration with Dr. Cardenas becomes so valuable. While I focus on the biomechanical, neurological, and functional medicine aspects, Dr. Cardenas provides critical medical oversight.

• Ruling Out Other Pathologies: Cardenas’s internal medicine expertise is essential to ensure no other systemic diseases (e.g., autoimmune conditions, metabolic disorders) are mimicking or contributing to the patient’s symptoms.
• Advanced Imaging and Referrals: If the patient’s condition did not improve as expected, we would decide on next steps together. This might involve ordering an MRI or MR arthrogram to look for a paralabral cyst or a significant labral tear, or an EMG/NCS (electromyography/nerve conduction study) to quantify the degree of nerve damage definitively. If surgical decompression were ever deemed necessary, Dr. Cardenas would facilitate the referral to a trusted orthopedic surgeon.
• Medication Management: While we prioritize non-pharmacological approaches, Dr. Cardenas can manage prescriptions for anti-inflammatory medications or neuropathic pain agents if they are needed to control severe symptoms in the short term, allowing the patient to engage more effectively in their rehabilitation program.

This integrated model ensures that all bases are covered. The patient receives chiropractic care to restore function, functional medicine to address root causes, and the highest standard of medical care to ensure diagnostic accuracy and safety. This collaborative approach goes beyond treating pain; it aims to restore optimal function, enhance performance, and build resilience against future injury. For our young weightlifter, this means not just getting out of pain, but getting back into the gym stronger, safer, and with a deeper understanding of how to care for his body long-term.
