Chiropractic Rehabilitation Techniques to Reduce Shoulder Pain

Learn about chiropractic rehabilitation approaches for shoulder pain to help you regain function and relieve discomfort effectively.

Introduction Abstract

Welcome to Health Voice 360. I am Dr. Alexander Jimenez, and in my practice, I frequently encounter complex musculoskeletal conditions that significantly impact my patients’ quality of life. This educational post will provide a comprehensive, evidence-based exploration of suprascapular neuropathy, a challenging and often misdiagnosed cause of chronic shoulder pain and weakness. Today, we will delve into the case of an 18-year-old weightlifter who presented to my clinic with a five-month history of insidious, progressive left shoulder pain, weakness, and notable muscle atrophy. This case is a strong clinical example for dissecting the intricate details of this condition. We will begin by exploring the complex anatomy of the shoulder, focusing on the path of the suprascapular nerve as it travels through critical anatomical choke points like the suprascapular notch and the spinoglenoid notch. Understanding this anatomical journey is paramount to grasping how and why compression occurs. Building on this anatomical foundation, we will discuss the pathophysiology of nerve compression, examining how mechanical forces translate into cellular and physiological dysfunction that leads to the hallmark symptoms of pain, weakness, and muscle wasting.

We will then transition to a detailed discussion of the clinical presentation. I will share insights from my clinical observations on recognizing the subtle signs of suprascapular neuropathy and distinguishing it from more common shoulder pathologies like rotator cuff tears or cervical radiculopathy. A crucial part of this post will focus on the diagnostic process. We will cover the importance of a thorough physical examination, including specific orthopedic tests designed to provoke symptoms and assess muscle function. We will also explore the role of advanced diagnostic imaging and electrodiagnostic studies, such as Nerve Conduction Velocity (NCV) and Electromyography (EMG), which are the gold standards for confirming the diagnosis and quantifying the extent of nerve damage. This discussion focuses on management strategies. I will walk you through a detailed, step-by-step explanation of the diagnostic and therapeutic suprascapular nerve block performed on our young patient. We will cover the rationale, precise landmark-guided technique, injectate pharmacology, and immediate post-procedure goals. Beyond this intervention, we will explore a spectrum of conservative and interventional treatment options, from physical therapy and activity modification to more advanced techniques like hydrodissection and surgical decompression, explaining the clinical reasoning behind each approach. This comprehensive guide aims to empower both patients and healthcare professionals with a deeper, evidence-based understanding of suprascapular neuropathy, fostering better diagnosis and more effective management of this debilitating condition.

A Clinical Case Study: The Young Athlete’s Shoulder

In my years of practice as both a Chiropractor and a Family Nurse Practitioner, I’ve learned that a patient’s story is the most critical piece of the diagnostic puzzle. Today, I want to share a particularly illustrative case that highlights a frequently overlooked condition: suprascapular neuropathy.

This morning, an 18-year-old gentleman came into my clinic. He presented with a chief complaint of a vague, persistent pain localized to his left shoulder, which had been troubling him for the past five months. He described the onset as insidious—there was no single traumatic event he could recall. Instead, the discomfort and associated weakness developed gradually and, more concerningly, progressively worsened over time.

One key diagnostic clue he provided was nocturnal pain. He reported that the pain in his left shoulder would often wake him from sleep, a classic sign of an inflammatory or compressive process. Furthermore, he is an avid weightlifter and has been dedicated to this pursuit for the last seven or eight years. This history is highly significant. His athletic endeavors, which involve repetitive and heavy overhead movements, placed him in a high-risk category for specific types of shoulder injuries. He noted increasing difficulty and weakness in the gym, specifically during exercises that required abduction (lifting the arm out to the side) and external rotation (rotating the arm outward, as if preparing to throw a ball).

On physical examination, the findings pointed strongly to a neurological issue rather than a simple muscle strain. I noted visible atrophy, or wasting, of the left infraspinatus muscle compared with the well-developed musculature on the right. I also observed a similar, albeit more subtle, atrophy of the supraspinatus muscle on the same left side. This pattern of muscle wasting involving these two rotator cuff muscles is a hallmark sign that strongly suggests a problem with the nerve that supplies them—the suprascapular nerve.

Based on this constellation of findings—the insidious onset, progressive weakness, nocturnal pain, specific functional deficits in abduction and external rotation, and the tell-tale atrophy of the supraspinatus and infraspinatus muscles—I formed a strong clinical suspicion of suprascapular neuropathy. This is a compression neuropathy, a condition where the suprascapular nerve becomes entrapped or compressed as it passes through a narrow anatomical passageway known as the suprascapular notch.

Understanding the Anatomy of Suprascapular Neuropathy

To understand why this young athlete is experiencing these symptoms, we must first take a brief look at the intricate anatomy of the shoulder girdle and the suprascapular nerve’s specific path. This nerve is the unsung hero of shoulder function, and its compromise can lead to devastating functional loss.

The Origin and Path of the Suprascapular Nerve

The suprascapular nerve originates from the brachial plexus, the complex network of nerves that emanates from the spinal cord in the neck (specifically, from the C5 and C6 spinal nerve roots) and controls the muscles and sensation of the entire upper limb. After forming from the upper trunk of the brachial plexus, the suprascapular nerve embarks on a long, winding journey toward the back of the shoulder blade, or scapula.

Its path makes it vulnerable. The nerve travels posteriorly, deep to the clavicle and the large trapezius muscle. Its first major challenge is navigating the suprascapular notch. This small, U-shaped or V-shaped indentation lies on the scapula’s superior border. The superior transverse scapular ligament transforms this notch into a foramen, or tunnel, by stretching across the top of the notch. The suprascapular nerve passes under this ligament, while the suprascapular artery and vein pass over it. This tight passageway is the most common site of nerve compression, accounting for the majority of suprascapular neuropathy cases.

Once the nerve passes through the suprascapular notch, it enters the supraspinatus fossa, a shallow depression on the posterior surface of the scapula above the scapular spine. Here, it gives off its first set of motor branches, which innervate the supraspinatus muscle. This muscle is a critical component of the rotator cuff and initiates the first 15-20 degrees of shoulder abduction.

The nerve then continues its journey, wrapping around the lateral edge of the scapular spine to enter the spinoglenoid notch. This is the second potential site of compression. The spinoglenoid notch is the space between the spine of the scapula and the glenoid fossa (the “socket” of the shoulder joint). As it passes through this notch, the nerve enters the infraspinatus fossa, the larger depression below the scapular spine. Here, it terminates by innervating the infraspinatus muscle. The infraspinatus is the primary muscle responsible for external rotation of the shoulder.

The suprascapular nerve is primarily a motor nerve that supplies these two key rotator cuff muscles. It also carries some sensory fibers that provide sensation to the acromioclavicular (AC) and glenohumeral (shoulder) joints, which can contribute to the deep, aching pain patients experience.

The Pathophysiology: How Compression Causes Damage

Nerve compression is not a simple on/off switch; it’s a progressive injury process. When a nerve like the suprascapular nerve is compressed, a cascade of physiological events begins.

1. Mechanical Irritation and Ischemia: The initial compression irritates the nerve mechanically. More importantly, it compromises the nerve’s delicate blood supply, known as the vasa nervorum. This leads to ischemia, or a lack of oxygen and nutrients. The nerve’s metabolic processes are disrupted, impairing function. Initially, this may cause only transient symptoms like tingling or pain that resolve when the compression is relieved.
2. Inflammation and Edema: Chronic compression triggers an inflammatory response. The body sends inflammatory cells to the area, leading to edema, or swelling, of the nerve and surrounding tissues. This swelling is counterproductive because it further increases pressure within the already tight anatomical space (e.g., the suprascapular notch), creating a vicious cycle of compression, ischemia, and inflammation.
3. Demyelination: Nerves are like electrical wires, insulated by a fatty substance called myelin. Myelin allows rapid, efficient transmission of nerve impulses through a process called saltatory conduction. Prolonged compression damages the myelin sheath, a process known as demyelination. This is like stripping the insulation off a wire. The nerve signal slows down or can be blocked entirely, leading to muscle weakness and delayed muscle contraction.
4. Axonal Damage (Wallerian Degeneration): If the compression is severe and prolonged, it can lead to damage to the core of the nerve fiber itself, the axon. This is a much more serious form of injury. When the axon is damaged, the portion of the nerve distal to the injury site begins to degenerate in a process called Wallerian degeneration. This leads to a loss of connection between the nerve and the muscle it supplies.
5. Muscle Atrophy: A muscle requires constant nerve stimulation to maintain its health and bulk. When the nerve supply is cut off due to axonal damage, the muscle fibers begin to shrink and waste away. This is neurogenic atrophy. The visible wasting of the supraspinatus and infraspinatus muscles in our young patient is a clear clinical sign that the nerve injury has progressed beyond simple irritation and has caused significant axonal damage.

In our weightlifter’s case, repetitive overhead lifting and extreme ranges of motion likely caused either hypertrophy (enlargement) of the surrounding muscles or repetitive traction and irritation of the nerve as it passed through the suprascapular notch, initiating this damaging cascade. Another possibility is an anatomical variant, such as a narrowed notch or a calcified ligament, that made him more susceptible to injury.

The Diagnostic Procedure: A Landmark-Guided Suprascapular Nerve Block

Given my strong suspicion of suprascapular neuropathy at the suprascapular notch, the plan for today was twofold: to confirm the diagnosis and to provide immediate therapeutic relief. The most effective way to achieve both is through a diagnostic and therapeutic suprascapular nerve block. The logic is simple: if we anesthetize the nerve at the suspected site of compression and the patient’s pain resolves and function improves, it strongly confirms that the nerve is the source of the problem. The corticosteroid in the injection will then reduce inflammation and swelling around the nerve, providing longer-term benefit.

What follows is a detailed, step-by-step breakdown of the procedure we performed in the clinic today. This precise, landmark-based technique requires a thorough understanding of surface anatomy.

Step 1: Identifying the Anatomical Landmarks

The success of this injection hinges on accurately locating the suprascapular notch, which lies deep to several muscle layers. We cannot see it or palpate it directly, so we must use reliable bony landmarks to triangulate its position.

1. The Coracoid Process: First, I located the coracoid process. This hook-like bony projection is on the front of the scapula. I palpated deep in the soft tissue just medial to the head of the humerus. I asked the patient, “Does that hurt a little bit? Right there?” to confirm I was on a bony prominence. He initially said no, but with a slight adjustment of my finger, he confirmed with a “Yeah, you got it. Felt that.” This confirmation is vital. Once located, I placed a small mark on his skin with a surgical marker.
2. The Spine of the Scapula and the Acromion: Next, I moved to the back of his shoulder to map out the spine of the scapula. This is the prominent horizontal ridge of bone you can easily feel on the upper back. I marked the entire length of the spine, from its medial border where it meets the rest of the scapular body to its lateral tip, the acromion. I placed a specific mark at the acromion tip
3. Finding the Midpoint: The next critical landmark is the midpoint of the scapular spine. I measured the distance between the medial border of the scapular spine and the tip of the acromion and marked the halfway point. This specific point serves as one of the anchors for our final injection line.

Step 2: Triangulating the Injection Site

Now, with our three key landmarks identified (the coracoid process, the tip of the acromion, and the midpoint of the scapular spine), we can draw lines to our target.

• First, visualize a line between the midpoint of the scapular spine and the coracoid process. This line essentially cuts across the top portion of the scapula.
• Our injection point is located at the midpoint of this newly drawn line.

As I explained to the patient, “So it’s going to be right here along this line right there. And our injection point is going to be right at the midpoint of that line.” This places us directly over the supraspinatus fossa, the anatomical depression where the supraspinatus muscle resides. Crucially, this surface location corresponds to the deep anatomical location of the suprascapular notch. This meticulous mapping is key to a safe, effective injection, ensuring we are as close to the target nerve as possible.

Once I was confident in the location, I used the retracted tip of a ballpoint pen to make a firm impression on the skin. This creates a small, temporary mark that won’t wash away during the skin sterilization process.

Step 3: Aseptic Preparation of the Skin

Infection is a potential risk with any injection procedure, so a strict aseptic technique is non-negotiable.

1. Alcohol Prep: First, I used an alcohol swab to clean the entire area thoroughly. This serves two purposes: it begins the disinfection process and, as I mentioned to the patient, it “removes all these marks from your shoulder,” leaving only the small impression from the pen tip.
2. Betadine Application: Following the alcohol, I applied Betadine (povidone-iodine), a powerful antiseptic solution. I told him, “This will kill germs,” to ensure he understood why the cold, brown liquid was on his skin. I applied it in a circular motion, starting at the injection site and spiraling outward to sterilize the area.

Step 4: Preparing the Injectate and Anesthetizing the Skin

The medication cocktail for this procedure is chosen specifically for its diagnostic and therapeutic properties.

• The Medication: I prepared a syringe containing 1 mL of 1% Lidocaine with epinephrine and 1 mL of a corticosteroid solution.

• • Lidocaine: This is a local anesthetic. It numbs the nerve almost immediately. The rapid pain relief it provides is the diagnostic component of the block. If the pain goes away, we’ve confirmed the nerve is the culprit.
  • Epinephrine: This is a vasoconstrictor often added to local anesthetics. It serves two important functions. First, it constricts local blood vessels, which reduces bleeding at the injection site. Second, and more importantly, it slows lidocaine absorption away from the injection site, prolonging its anesthetic effect and keeping it concentrated around the target nerve.
  • Corticosteroid: This is a powerful anti-inflammatory medication (e.g., Triamcinolone, Methylprednisolone). Its purpose is therapeutic. It will work over the next several days to weeks to decrease the inflammation and swelling (edema) around the compressed nerve, hopefully providing lasting relief and creating a better environment for the nerve to heal.

• The Needle: I used a 1-inch, 25-gauge needle. The 25-gauge needle is relatively thin to minimize patient discomfort, and the 1-inch length is typically sufficient to reach the floor of the supraspinatus fossa in a lean individual like this patient.
• Skin Anesthesia: Before inserting the needle, I used a topical anesthetic to numb the skin itself, making the procedure as comfortable as possible. I used Pain-Ease vapor coolant spray. I explained, “Here’s the free spray I was telling you about.” I sprayed it directly on the marked injection site until the skin turned white, indicating it was thoroughly chilled and numb. I then checked, “Does that hurt at all?” He confirmed, “No.” This small step significantly improves the patient experience.

Step 5: The Injection

With the site prepped and the patient comfortable, it was time to inject. The technique must be precise and deliberate.

1. Insertion: I directed the needle perpendicularly to the skin, straight down. The goal is to advance the needle until it makes gentle contact with the bone at the floor of the supraspinatus fossa. I announced, “Come directly down. Touch the bone.” This bony feedback is a critical safety measure; it confirms our depth and ensures we are not too deep, where major vascular structures lie.
2. Retraction and Aspiration: Once I felt the bone, I withdrew the needle by about one millimeter. This creates a small space for the medication to disperse. Before injecting, the most critical safety step is to aspirate, which means pulling back on the plunger of the syringe. I stated, “Make sure you’re not in the suprascapular artery.” If blood returned to the syringe upon aspiration, it would indicate the needle tip is inside a blood vessel. Injecting into a vessel is dangerous, as the anesthetic and steroid would be carried away systemically instead of treating the local area, and could have adverse cardiac effects. The aspiration was negative (no blood return).
3. Injection: With safety confirmed, I slowly and steadily injected the 2 mL of solution. The patient felt pressure but no sharp pain. I noted, “There we go. That’s injected there.”

Step 6: Post-Procedure Care and Immediate Assessment

The procedure itself is quick, but the moments immediately following are crucial for both efficacy and assessment.

1. Bandage and Massage: I immediately placed a small bandage over the site. Then, I instructed the patient on a vital step: “Go ahead and take your other hand and rub this. Rub this in… use firm fingertips right there, and kind of firmly rub in.” This firm massage helps to manually disperse the medication throughout the fascial planes of the supraspinatus fossa, ensuring it fully bathes the suprascapular nerve and the surrounding tissues.
2. Immediate Mobilization: After a moment of massage, I had him stop and immediately begin moving his arm. This is not for exercise, but to further spread the medication.

• • Abduction: “Let’s go ahead and bring your arm up like that, and down… do that a couple of times, and do it a little faster.” As I observed him, I noted, “We’re basically running the arm through abduction, there, to spread it out here in the area. That’s the supraspinatus muscle that’s responsible for that, for the most part.” This movement specifically engages the muscle whose nerve supply we just targeted. I also made a clinical observation: “Although you can see he’s got quite a bit of deltoid that kicks in here.” This is a classic compensatory pattern. Because his supraspinatus is weak and atrophied, his larger deltoid overworks to accomplish abduction.
  • External Rotation: Next, I instructed him, “And now let’s do external rotation, rotate it out like that, back and forth a few times.” This movement specifically targets the infraspinatus muscle, the second muscle supplied by the suprascapular nerve.

By having him perform these movements immediately, we are using the muscles themselves as a pump to help distribute the anesthetic and steroid solution around the nerve. The near-immediate improvement in his ability to perform these motions, with reduced pain, provides instant positive feedback and confirms the block’s diagnostic accuracy. He tolerated the entire procedure exceptionally well, stating that it did not hurt. This successful outcome provides us with a clear diagnosis and the first step on his path to recovery.

Broader Treatment Strategies and Future Considerations

While the nerve block is a powerful tool, it is often just one component of a comprehensive treatment plan for suprascapular neuropathy. The long-term goal is to resolve the nerve compression, restore muscle function, and prevent recurrence.

Conservative Management

For many patients, especially those with less severe symptoms or no significant atrophy, conservative care is the first-line treatment.

• Activity Modification: The first and most crucial step is to identify and modify activities that cause or worsen nerve compression. For our young weightlifter, this means temporarily stopping heavy overhead lifting, bench presses, and any other exercises that stress the shoulder girdle. This “relative rest” is not complete immobilization but a strategic avoidance of aggravating movements.
• Physical Therapy: A skilled physical therapist is an invaluable partner in managing this condition. The goals of physical therapy are multifaceted:

• • Pain and Inflammation Control: Therapists may use modalities like ice, ultrasound, or electrical stimulation in the initial phase to help manage pain and inflammation.
  • Postural Re-education: Poor posture, particularly a forward-rolled shoulder and “scapular dyskinesis” (abnormal movement of the shoulder blade), can contribute to narrowing the space for the nerve. Therapy focuses on strengthening the periscapular muscles (rhomboids, serratus anterior, lower trapezius) to improve scapular positioning and movement mechanics.
  • Stretching: Gentle stretching of the posterior shoulder capsule and pectoral muscles can help to open up the shoulder joint and reduce tension.
  • Nerve Gliding/Flossing: These are specific, gentle exercises designed to mobilize the suprascapular nerve within its fascial planes, helping to break up minor adhesions and improve its mobility.
  • Strengthening: As pain subsides, a carefully progressed strengthening program is initiated. The focus is on the atrophied supraspinatus and infraspinatus muscles, but it must be done in a way that doesn’t re-aggravate the nerve. The program also includes strengthening the entire rotator cuff and the larger scapular stabilizing muscles to create a more stable and functional shoulder girdle.

Advanced Interventional Options

If conservative management and injections fail to provide lasting relief, or if there is profound muscle atrophy and weakness from the outset, more advanced interventions may be considered.

• Ultrasound-Guided Hydrodissection: This is a more advanced version of the injection I performed. Using real-time ultrasound imaging to visualize the nerve, the ligament, and the surrounding structures, a larger volume of fluid (typically saline or a mixture with anesthetic/steroid) is injected precisely into the plane between the nerve and the overlying transverse scapular ligament. The fluid’s hydraulic pressure “dissects,” or separates, the nerve from the compressive structures, physically freeing it. Ultrasound guidance significantly increases the precision and safety of the procedure.
• Pulsed Radiofrequency (PRF) Ablation: For cases dominated by chronic pain, PRF may be an option. This procedure involves placing a specialized needle next to the suprascapular nerve (again, often under ultrasound or fluoroscopic guidance). Instead of delivering continuous heat to destroy the nerve (which would cause muscle paralysis), PRF delivers short bursts of radiofrequency energy. This is thought to “stun” the sensory components of the nerve, modulating the pain signals without damaging the motor fibers. It is a neuromodulatory treatment for pain, not a cure for the compression itself.

Surgical Decompression

In cases of severe, unremitting compression, especially when there is evidence of a physical mass (like a ganglion cyst) or a severely calcified ligament, or when profound muscle atrophy does not improve, surgical intervention is the definitive treatment.

• Arthroscopic Decompression: The most common surgical approach today is arthroscopic. The surgeon inserts a small camera (arthroscope) and specialized instruments through small incisions. They can then visualize the superior transverse scapular ligament and carefully cut it (a “release”), immediately relieving the pressure on the suprascapular nerve if compression also occurs at the spinoglenoid notch; surgeons can often address it in the same procedure.
• Open Decompression: While less common now, an open surgical approach may be necessary in complex cases, such as when a large cyst needs removal.

The decision to proceed with surgery is based on the failure of less invasive treatments, the severity of the neurological deficit, and the findings from electrodiagnostic studies (EMG/NCV), which can quantify the degree of nerve damage and help predict the potential for recovery. For our young patient, we will monitor his progress closely. The goal is for the injection to provide a window of opportunity for intensive physical therapy to work. If his strength and muscle bulk do not begin to return, we will need to obtain electrodiagnostic studies and consider these more advanced options to give him the best chance of returning to the sport he loves.

Summary

The educational post presented on September 2, 2026, offers a comprehensive examination of suprascapular neuropathy, using a detailed clinical case of an 18-year-old weightlifter as a framework. The presentation begins by outlining the patient’s five-month history of progressive left shoulder pain, weakness, and nocturnal symptoms. Critical physical exam findings, specifically marked atrophy of the infraspinatus and supraspinatus muscles, are highlighted as cardinal signs pointing to a neurological deficit involving the suprascapular nerve. The post then transitions into a foundational discussion of the relevant anatomy, meticulously tracing the path of the suprascapular nerve from the brachial plexus through its two primary potential entrapment sites: the suprascapular notch and the spinoglenoid notch. This anatomical review is directly linked to the pathophysiology of nerve compression, explaining the cascade of events from initial mechanical irritation and ischemia to chronic inflammation, demyelination, and eventual axonal loss leading to muscle atrophy. A significant portion of the post is dedicated to a step-by-step procedural explanation of a landmark-guided diagnostic and therapeutic suprascapular nerve block. This includes the precise method for identifying anatomical landmarks (coracoid process, scapular spine, acromion), preparing the sterile field, formulating the injectate (Lidocaine with epinephrine and a corticosteroid), and executing the injection safely and effectively. The rationale behind immediate post-procedure mobilization is also explained as a means to enhance medication dispersal. Finally, the discussion broadens to cover a full spectrum of management strategies, from conservative care like activity modification and physical therapy to more advanced interventions such as ultrasound-guided hydrodissection and surgical decompression, providing a complete clinical picture of this challenging condition.

Conclusion

In conclusion, suprascapular neuropathy is a critical yet often under-diagnosed cause of shoulder pain and dysfunction, particularly in athletic populations. As demonstrated by the case of the young weightlifter, a thorough history and a keen eye for specific patterns of muscle atrophy are paramount to accurate clinical suspicion. The diagnostic and therapeutic nerve block is a cornerstone of management, providing both diagnostic confirmation and therapeutic relief by directly targeting inflammation and compression at the suprascapular notch. This intervention creates a therapeutic window, allowing more effective engagement in physical therapy to correct underlying biomechanical faults and strengthen the weakened rotator cuff muscles. While many patients can be managed successfully with conservative and minimally invasive techniques, it is essential to recognize the indications for more advanced diagnostics, such as EMG/NCV, and further interventions like surgical release, especially in cases of profound neurological deficit or failure to progress. A multidisciplinary, evidence-based approach is key to restoring function and preventing long-term disability, ultimately allowing patients to return to their desired activities.

Key Insights

• Atrophy is the Telltale Sign: While shoulder pain and weakness are common, the specific, isolated atrophy of the supraspinatus and/or infraspinatus muscles is a powerful clinical indicator that should immediately raise suspicion for suprascapular neuropathy over more common pathologies like rotator cuff tears.
• Anatomy Dictates Pathology: The vulnerability of the suprascapular nerve is a direct result of its anatomical course through tight fibro-osseous tunnels (the suprascapular and spinoglenoid notches). Understanding this anatomy is essential for both diagnosis and treatment.
• The Dual Role of Nerve Blocks: A suprascapular nerve block is not just a treatment; it is a powerful diagnostic tool. The immediate, albeit temporary, pain relief after an anesthetic block confirms the nerve’s role as the pain generator, solidifying the diagnosis.
• Compensation Can Mask Weakness: As observed in the patient, strong compensatory muscle patterns (e.g., overuse of the deltoid for abduction) can mask the true extent of rotator cuff weakness. A detailed functional assessment is crucial to uncover these deficits.
• Treatment is a Spectrum: Management of suprascapular neuropathy exists on a continuum, from activity modification and physical therapy to injections and, ultimately, surgical decompression. Treatment must be tailored to symptom severity, the degree of nerve damage, and the patient’s response to initial therapies.
