Central Pain Syndrome

Editor: Amy Givler Updated: 5/3/2025 8:22:25 PM

Introduction

Central sensitization occurs when the nervous system remains in a state of hyperactivity, resulting in increased neuronal excitability and enhanced synaptic transmission.[1][2] Despite limited input from the peripheral nervous system (PNS), the central nervous system (CNS) persistently amplifies pain signals. This hyperexcitability results in heightened pain sensitivity through the upregulation of ion channels, reduced inhibition, and maladaptive plasticity.[3] This state, which includes "wind-up" (temporal summation) as an acute precursor, causes ordinary touch to produce pain (allodynia) or a mild stimulus to feel more painful (hyperalgesia).[4]

Central pain syndrome (CPS), a subset of centralized pain disorders, results from CNS conditions such as stroke or spinal cord injury. CPS involves mechanisms distinct from those of nociplastic pain, such as that seen in fibromyalgia. While less common than nociplastic pain, CPS often develops following neurological injuries, making it crucial for healthcare providers to differentiate it from other centralized pain syndromes to guide appropriate interventions. Cold temperatures or emotional stress may exacerbate symptoms but are not required for diagnosis.

CPS frequently coexists with memory impairment and anxiety, reflecting shared neurobiological pathways. Treatment involves targeted CNS therapies, including antidepressants like serotonin-norepinephrine reuptake inhibitors (SNRIs) and anticonvulsants such as gabapentin. Traditional pain relievers, including nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids, are typically ineffective for centrally mediated pain. Chronic pain affects up to 1 in 5 adults, with a substantial proportion experiencing centralized pain symptoms.[5]

Etiology

Historically, CPS was considered a psychiatric diagnosis following traumatic brain injury or thought to be a diagnosis of exclusion. The theory behind CPS was that it represented a dysfunction of the nervous system, unlike adaptive changes seen with musculoskeletal (nociceptive) pain.[6] For example, withdrawing one's hand from an open flame is beneficial, as pain serves as a protective mechanism to limit harm. CPS, however, was thought to represent pain without protective value. Not only is it nonprotective, but it is also maladaptive.

Sensory amplification and pain intensify as multiple systemic syndromes overlap. An estimated 2% to 4% of the population experience fibromyalgia, 1% have chronic fatigue, and 4% live with somatoform disorders. Additionally, regional pain syndromes and psychiatric disorders have a significant overlap.

CPS is a type of neuropathic pain that originates in the CNS. The condition can occur in patients with a history of multiple sclerosis or recent stroke. Acute pain that becomes chronic may undergo centralization, putting patients at risk of developing centralized pain.

Although patients with CPS consider their pain to be peripheral, it is mostly centralized. The neural signal becomes amplified, leading to hyperalgesia and allodynia. Pain centralizes over time when peripheral pain occurs with nociceptive pain, such as in rheumatoid arthritis. The pain then enters a mixed state. Chronic back pain serves as an example of peripheral pain centralizing with time.[7][8]

Risk factors for fibromyalgia mirror those for CPS. These risk factors include trauma, infection, chronic stress, obesity, and depression. Centralized sensitization occurs with minimal or no nociceptive input. Functional neuroimaging can aid in the diagnosis of CPS.

In reality, centralized pain is not mutually exclusive from other types of pain. An overlap exists between pain states. Any central pain state can include a component of peripheral pain, such as peripheral neuropathy. Additionally, a significant family predisposition to CPS exists.[9][10] Psychological stressors can also trigger worsening symptoms. In many cases, environmental factors cause a triggering event in patients with genetic susceptibility, leading to widespread, centralized pain.[11][12] Thus, environmental stressors require management. Early life trauma, infection, or emotional stress can cause centralized pain in 5% to 10% of patients.[13][14]

An estimated 50% environmental component contributes to developing centralized pain, with a 50% genetic component. First-degree relatives face an 8-fold higher risk of developing centralized pain compared to the general population. However, no significant difference exists based on the sex of the patient or family member. The genetic association is more prominent in families with a history of mood disorders.[15][16] A genetic component for centralized pain may exist, but a single genetic polymorphism has not been identified.[17]

Epidemiology

Chronic widespread pain seen in centralized pain occurs in 10% to 40% of patients with rheumatoid arthritis, psoriatic arthritis, osteoarthritis, spondyloarthritis, and systemic lupus erythematosus (SLE). Centralized pain occurs in 5% to 15% of the general population, most of whom have fibromyalgia. The criteria for fibromyalgia diagnosis overlap considerably with centralized pain, with patients who report severe fatigue having a fivefold increased risk for widespread pain.[18] The prevalence of overlap between centralized pain and knee osteoarthritis ranges from 10% to 15%. The prevalence increases if knee pain is bilateral compared to unilateral knee pain.[19][20][21]

The reported centralized pain in rheumatoid arthritis is estimated to be 13% to 40%. One concern with this patient population is overtreating rheumatoid arthritis due to increased symptoms, which actually arise from centralized pain. Inflammatory markers are lower in patients with comorbid fibromyalgia and rheumatoid arthritis, while these patients report a decreased quality of life compared to those with rheumatoid arthritis alone.[22][23]

Centralized pain appears in 10% to 30% of patients with spondyloarthritis. Separately, 13% to 20% of patients with ankylosing spondylitis meet the criteria for fibromyalgia.[24][25][26] Patients with widespread pain are much more likely to have clinically significant fatigue with a comorbid mood disorder, with moderate-to-severe symptoms. In one study, centralized pain was present in 53% of patients with psoriatic arthritis but only 5% of the average population.[27] Patients with centralized pain were also more likely to be lost to follow-up after initiating treatment. Separately, centralized pain presents in 20% to 40% of patients with SLE or Sjögren syndrome. Furthermore, symptoms were more prevalent as chronic diseases progressed and in patients with comorbid depression.[28][29]

Over 1/3 of women with chronic back pain suffer from centralized pain. The daily impact of centralized pain is significant in patients with chronic back pain, including severe limitations in their activity level. Given the considerable prevalence of widespread, centralized pain in women with chronic low back pain, CPS warrants consideration in the differential diagnosis for this patient population.[30]

Pathophysiology

The pathogenesis of CPS remains unclear. The underlying mechanism may resemble that of neuropathic pain arising from other body regions or may involve overlapping lesions, features, and associated conditions.[31] Both central and peripheral mechanisms contribute to neuropathic pain, including alterations in the brain, spinal cord, and descending modulatory pathways.[32] Commonly affected regions include the lateral medulla, pontine base, and lateral or posterior thalamus.[33]

Toxicokinetics

No current peer-reviewed data demonstrate a link between any specific toxin and CPS. However, any etiology capable of inducing chronic pain, such as chemical, drug (eg, disease-modifying antirheumatic drugs), or venom exposure, may plausibly contribute to centralized pain through chronic pain mechanisms.[34]

History and Physical

The diagnosis of CPS requires symptoms persisting for a minimum of 3 months, characterized by widespread allodynia or hyperalgesia in the absence of an identifiable nociceptive source. CPS is defined by the International Association for the Study of Pain (IASP) as pain caused by a CNS lesion or disease. Central sensitization, characterized by increased responsiveness of nociceptive neurons in the CNS to normal or subthreshold input, is a key mechanism that may contribute to the condition. CPS may present as generalized pain or involve multiple, discrete anatomical regions. Reproducible pain elicited by normal pressure during palpation typically reflects hyperalgesia or allodynia secondary to mechanical stimulation of joints or muscles.

Clinical features frequently associated with CPS include mood disturbances, fatigue, cognitive impairment, disordered sleep, pain catastrophizing, and symptoms suggestive of neuropathic pain, such as burning, numbness, tingling, and paresthesias. Affected individuals often report multifocal pain and memory complaints, and may meet diagnostic criteria for major depressive or generalized anxiety disorder. Noxious stimuli, such as extreme temperatures or loud auditory input, may exacerbate symptom intensity.[35] Using a standardized body diagram may assist in documenting pain distribution.

A thorough pain history should include the onset, description, location, radiation, quality, and severity of the pain. Additional elements include the mechanism of injury (if applicable), aggravating and relieving factors, frequency of symptoms, and presence of breakthrough pain. Associated features should also be assessed, such as muscle spasms or aches, temperature changes, restricted range of motion, morning stiffness, weakness, muscle strength, sensory changes, and alterations in hair, skin, or nail integrity.

Separately, the physical examination should include a detailed neurological assessment and a focused examination of the painful area. When evaluating for CPS, a complete musculoskeletal examination is recommended. Assessment for symmetrical tender points, characteristic of fibromyalgia, may also provide diagnostic insight. Ay tenderness over soft tissues or joints should be documented.

To support a diagnosis of CPS, pain often appears in a widespread distribution, affecting the axial skeleton, both sides of the body, and regions above and below the diaphragm. CPS becomes less likely when findings include swelling, structural abnormalities, focal neurologic deficits, or signs of joint inflammation.

Evaluation

The diagnosis of CPS remains primarily clinical, as the results of standard laboratory tests, including complete blood count, erythrocyte sedimentation rate, C-reactive protein, thyroid-stimulating hormone, and creatine kinase, are typically unremarkable.[36] Laboratory testing should be reserved for cases with clinical suspicion warranting further evaluation. Genetic biomarkers for CPS are currently limited, and rheumatologic markers such as rheumatoid factor and antinuclear antibody are not indicated unless an autoimmune process is suspected.

Screening tools for CPS include the Central Sensitization Inventory (CSI) and painDETECT. These modalities assist in evaluating neuropathic pain and centralized pain syndromes such as fibromyalgia, respectively.[37] Distinguishing between central and peripheral origins of pain can be challenging. For instance, painDETECT cannot localize the source of pain to either the CNS or PNS with precision.[38]

Neuroimaging, including magnetic resonance imaging (MRI) and functional MRI (fMRI), may support the diagnosis of CPS. FMRI has identified structural and functional brain alterations in patients with chronic pain conditions. Individuals with fibromyalgia, for example, often demonstrate distinct brain activation patterns. FMRI may help identify patients at risk for developing centralized pain disorders and contribute to diagnosis and prognosis.[39] Notable fMRI findings include reduced brain volume, decreased cortical thickness, and elevated levels of excitatory neurotransmitters.[40]

Furthermore, fMRI provides insight into connectivity between multiple brain regions, with the degree of alteration often correlating with the extent of a patient's pain. In fibromyalgia, fMRI may offer an objective measure of symptom severity.[41] Patients with fibromyalgia demonstrate pain-related brain activity patterns that differ from those in the general population. As a diagnostic tool, fMRI shows promise for future use in evaluating various chronic pain disorders.[42] Positron emission tomography (PET) and electroencephalography (EEG) have also revealed heightened pain responses in individuals with CPS.[43][44]

Treatment / Management

Treatment often targets the underlying chronic disease associated with centralized pain. Managing comorbid conditions can significantly reduce pain severity.[45] For instance, in knee osteoarthritis, neuroimaging abnormalities linked to centralized pain have improved following joint replacement. Central pain disorders tend to respond more effectively to neuromodulators, antiepileptics, or antidepressants than to pharmacologic agents targeting peripheral pain, such as NSAIDs or opioids.(B2)

Nonpharmacological strategies, particularly cognitive-behavioral therapy, serve as a foundation for managing CPS. A comprehensive, individualized approach is essential, as the underlying pathology may involve structural, immunologic, or inflammatory mechanisms. Strong evidence supports the use of neuromodulation techniques in the management of chronic pain. These methods include deep brain and motor cortex stimulation, peripheral nerve stimulation, and noninvasive modalities such as repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (tDCS), and transcutaneous electrical nerve stimulation (TENS).[46]

Self-directed or therapist-directed physical therapy techniques can include traction, massage, ultrasonographic therapy, hot or cold applications, positioning, meditation, active visualization, prayer, stretching exercises, and transcutaneous electrical nerve stimulation (TENS). Female patients with chronic pelvic pain syndrome may benefit from myofascial physical therapy, which can alleviate hypertonicity, improve endogenous inhibitory system function, reduce sensitivity to experimental pain, and provide psychological benefits.[47]

TENS is commonly used to treat rheumatoid arthritis and osteoarthritis. Electrodes are placed over or near the pain site, with the dipole positioned parallel to major nerve trunks. However, TENS can cause hypersensitivity as a side effect and should be avoided in individuals who are pregnant, have demand-type pacemakers, or intend to use it near the carotid sinus. Motor cortex (MCS) and deep brain (DBS) stimulation are effective treatment options for patients with refractory pain, central pain, and peripheral neuropathy.[48]

Occupational therapy proves beneficial for patients with chronic pain, particularly those with regional chronic pain syndrome. Occupational therapy promotes physical activity and helps manage physical symptoms.

Pharmacological treatments for CPS include tricyclic antidepressants, SNRIs, and anticonvulsants. Strong evidence supports the use of tricyclic antidepressants like amitriptyline, SNRIs like duloxetine and venlafaxine, and anticonvulsants like pregabalin and gabapentin. Moderate evidence exists for tramadol and selective serotonin reuptake inhibitors, while weak evidence supports the use of S-adenosyl-L-methionine.

Differential Diagnosis

Central sensitization manifests in various chronic pain disorders, including fibromyalgia, interstitial cystitis, temporomandibular joint disease, and irritable bowel syndrome. The differential diagnosis for CPS is broad, encompassing autoimmune disorders such as rheumatoid arthritis and polymyalgia rheumatica, myopathies, painful peripheral neuropathies, somatization disorder, malingering, and withdrawal phenomena from physiological or psychological dependence on habit-forming substances.

Central sensitization frequently accompanies chronic back and neck pain and is also associated with conditions such as trauma, carpal tunnel syndrome, complex regional pain syndrome, lateral epicondylitis, osteoarthritis, and joint hypermobility syndrome. CPS develops following a stroke or as a sequela of neurological disorders like multiple sclerosis.[49][50] A thalamic stroke is linked to a specific form of CPS. Finally, mood disorders, including major depressive disorder and generalized anxiety disorder, are often comorbid with CPS.

Toxicity and Adverse Effect Management

Potential Complications of Central Pain Syndrome Management

Adverse events from pain management procedures, when performed by well-trained and experienced interventionalists, are rare. The most common complication is a vasovagal response.[51] However, serious complications can arise, such as spinal block with critical hypotension, central respiratory depression from high cervical block, cardiac rhythm disturbances from inadvertent vascular uptake of injectate, acute contrast agent reactions, and pneumothorax. These complications require prompt management. Follow-up is essential not only for assessing the response and deciding whether to repeat or alter the procedure, but also for monitoring delayed infectious complications such as infectious discitis, epidural abscess, meningitis, and cellulitis.

Opiates, particularly when combined with other sedating medications, can cause respiratory depression. A responsible adult should be trained in the use of nasal naloxone. All sedating medications, including membrane stabilizers, whether alone or in combination, increase the risk of falls and related injuries, such as fractures, subdural hematomas, and even cognitive impairments that can hinder participation in cognitive behavioral therapies. The use of serotonergic drugs, either alone or in combination with tramadol (Controlled Substance Schedule IV), poses a significant drug interaction risk and carries the often-overlooked risk of serotonin syndrome.[52][53] Other medications, such as antineoplastics, also come with specific toxicities.

Most patients with CPS, or any chronic neuropathic pain, typically exhibit some degree of sensory peripheral neuropathy, which increases the risk of falls. This risk should be considered during physical and occupational therapy. Gait belts with contact guard assistance should be used for any patient with even slight balance issues.

Treatment Caveats

Individuals with CPS, like those with other chronic illnesses, often explore alternative or experimental therapies. Some may order "magic pain pills" online or mortgage their homes to travel abroad for treatment with a clinician who promises to "easily cure all these cases." While medical tourism is growing and some patients benefit from international treatment, patients are often vulnerable to exploitation, making such claims warrant careful evaluation. Oral and topical alternatives, such as herbal treatments and methylene blue, are receiving more research attention.[54] However, drug-herb and drug-chemical interactions should be carefully considered.

Another consideration is the lack of regulation. While some herbs or chemicals are well-established for their beneficial effects, product labels may not always accurately reflect the actual contents or confirm the absence of harmful substances, such as heavy metals.

Medical Oncology

Medical oncology consultation is warranted when malignancy is suspected, acute inflammatory markers are elevated without an identifiable cause, treatment of primary or metastatic lesions is indicated, or external beam radiation is being considered. Pain management in cancer survivors and patients undergoing cancer therapies involves special considerations, and a physician capable of recommending cannabis may be indicated.[55] In the U.S., relevant guidelines vary by state.

Prognosis

Prognosis improves in patients when the underlying disease causing pain can be cured, corrected, or managed, such as through shoulder replacement for osteoarthritis. Patients with osteoarthritis and centralized sensitization report pain reduction with pharmacological therapy targeting osteoarthritis, but experience worse pain outcomes following joint replacement surgery.[56]

In patients with osteoarthritis comorbid with CPS, pain severity does not correlate with radiographic severity of osteoarthritis. Additionally, patients with radiological evidence of osteoarthritis in a single joint are at increased risk of developing pain in multiple joints. This comorbid population also exhibits more synovitis and effusion in knee osteoarthritis.

Central sensitization contributes to inflammatory arthritis and affects a significant subset of the patient population. For example, patients with rheumatoid arthritis and comorbid fibromyalgia report worse pain, poorer mental health, and greater reliance on pain medications, including prednisone, despite having lower levels of inflammatory markers.[57][58] Patients with inflammatory arthritis and centralized sensitization experience poorer overall outcomes.[59] These patients also experience hyperalgesia at both articular and nonarticular sites.[60]

Complications

The impact of central sensitization extends across various conditions. In rheumatoid arthritis, central pain is linked with neuropathic symptoms, higher pain scores without changes in inflammatory markers, increased adverse outcomes, and reduced remission rates. Central sensitization also contributes to the increased use of opioids and higher pain severity in patients with osteoarthritis, leading to poorer patient outcomes.

Patients with bilateral knee pain are more likely to experience pain in other joints within a year. In spondyloarthritis, central sensitization is associated with worse outcomes, higher disease scores, and poorer treatment responses. In SLE, centralized pain is associated with greater sleep disturbances, mood changes, and worse overall outcomes. Patients with chronic back pain and central sensitization experience more intense pain and mood disturbances, as well as an increase in adverse outcomes. Joint hypermobility syndrome is linked to greater pain severity and poorer patient outcomes.

In carpal tunnel syndrome, central sensitization is associated with poorer surgical outcomes, while in lateral epicondylitis, it correlates with more severe pain, longer duration of pain, and a higher risk of failed treatments. For chronic whiplash injuries, centralized pain is associated with cognitive disturbances, more severe pain, and worse outcomes. Preoperative increases in fibromyalgia pain scores are associated with the use of more postoperative morphine equivalents and a reduced response to NSAIDs.[61]

Postoperative and Rehabilitation Care

Adequate pain control and early therapy following major surgeries are often believed to improve overall outcomes and reduce the incidence of chronic pain and disability. However, articles addressing this topic typically do so in an indirect and nonspecific manner, often focusing on specific disciplines or procedures, which requires extrapolation to broader contexts.[62][63] Nevertheless, the prevention of "sequelae of immobility," such as flexion contractures, deep vein thrombosis, muscle atrophy, compression neuropathies, and malnutrition, is universally accepted and does not require a peer-reviewed reference.

Consultations

The clinical scenario should guide specialist consultations. Rheumatology should be consulted for cases involving potential autoimmune disorders or elevated acute inflammatory markers. Neurology is necessary when concern arises for cerebrovascular accidents or other intracranial pathologies, such as demyelinating plaques.

Physical medicine and rehabilitation can assist with electrodiagnostic evaluations to differentiate between inflammatory and noninflammatory myopathies or identify the presence of peripheral neuropathy, especially if conditions like acute or chronic inflammatory demyelinating polyneuropathy are considered in the differential diagnosis.

Neurosurgery or orthopedic Surgery should be involved if concerns arise about structurally relevant and potentially correctable spinal or peripheral joint pathologies. Neurosurgery may also be required for temporal lobe stimulation in certain cases. Psychiatry or psychology is important for addressing potential somatization or hypochondriasis, as well as providing emotional support in the management of chronic, intractable pain.

Pain management consultations are essential for exploring both interventional and noninterventional options, including medication management and the consideration of implantable technologies, such as subarachnoid pain pumps. Vascular surgery or interventional radiology should be consulted if a vascular etiology is suspected.

Deterrence and Patient Education

CPS arises from heightened sensitivity within the CNS, lowering the threshold for pain perception. Understanding the pathophysiology, prevalence, and management of this condition is crucial for effective deterrence and treatment, especially in patients with chronic disease.

CPS manifests when the CNS becomes hyperresponsive, resulting in conditions like allodynia, or pain from normally nonpainful stimuli, and hyperalgesia, or exaggerated responses to painful stimuli. Up to 20% of individuals with chronic pain from any source may exhibit features of CPS, underscoring its clinical significance. Risk increases in patients with rheumatologic or musculoskeletal conditions persisting longer than 3 months, and both environmental and genetic factors contribute to its development.

Importantly, CPS can coexist with peripheral pain, further complicating diagnosis and management. Over time, chronic disease itself may amplify central sensitization, making dual pain syndromes more common. FMRI has emerged as a valuable diagnostic tool in distinguishing centralized pain patterns, enhancing clinical precision.

CPS affects numerous chronic disease states, notably worsening outcomes in osteoarthritis and rheumatoid arthritis. Addressing both the primary disease and CPS in tandem can lead to better symptom control. Effective management often requires collaboration between a primary care physician (PCP) and a pain medicine specialist. First-line pharmacologic interventions include antidepressants and anticonvulsants, which help modulate abnormal CNS pain processing.

Recognizing and managing centralized pain early in the course of chronic illness may deter progression to more debilitating states. A comprehensive, dual-focused approach offers the best opportunity for improving quality of life in patients with CPS.

Pearls and Other Issues

Clinicians should remember that pain is a symptom, not an etiology or a diagnosis. Every symptom reflects an underlying process, whether identified or not, treatable or not, or yet to be recognized in the current scientific literature. Approximately 20% of individuals with chronic pain from known causes also experience CPS or widespread pain in other regions. Effective treatment requires addressing both the primary cause of pain, acknowledging the limitations in treating certain conditions, and the distressing symptoms themselves, including pain.

Enhancing Healthcare Team Outcomes

Managing CPS requires a coordinated interprofessional approach involving PCPs, pain medicine specialists, pharmacists, nurses, and subspecialists such as rheumatologists or neurologists. Early recognition of centralized pain is essential, as it requires a distinct treatment strategy from peripheral or mechanical pain. CPS is associated with significant morbidity without appropriate diagnosis and management.

Initial evaluation typically includes laboratory tests such as complete blood count, erythrocyte sedimentation rate, C-reactive protein, creatine phosphokinase, and aldolase to help rule out underlying inflammatory or myopathic conditions. Clinicians should assess for hallmark features of central pain, including allodynia and hyperalgesia, particularly in patients with pain persisting longer than 3 months. Both genetic and environmental factors may contribute to the development and persistence of CPS.

Pharmacologic management often involves consultation with a pharmacist to guide the use of antidepressants, anticonvulsants, and other agents, including over-the-counter supplements or experimental options like methylene blue. Pain medicine specialists may consider neuromodulation for refractory cases. FMRI, when available, may provide supportive diagnostic information and should be discussed with a radiologist. Subspecialist input from rheumatology or neurology is often necessary to address underlying autoimmune or neurologic contributors to pain.

Management of CPS requires collaboration across multiple healthcare disciplines. However, coordination challenges frequently arise, with overlapping treatments, redundant testing, and polypharmacy increasing the risk of harm. To ensure consistency and safety, a single lead clinician, often referred to as the “quarterback,” should oversee the overall care plan and track each clinical decision. This role is commonly filled by neurologists or physicians in physical medicine and rehabilitation who hold additional board certification in pain management. Nonetheless, a PCP can also serve in this capacity if they have the interest and expertise, though many PCPs feel underprepared or lack the time to manage such complex cases comprehensively.

Preventing the progression to centralized sensitization is a critical goal due to the high burden of morbidity associated with this condition. Once established, symptoms of CPS are often persistent and do not fully resolve, and long-term outcomes remain guarded despite comprehensive care.

Nursing staff play a critical role in the care of individuals with centralized pain. These professionals serve as liaisons between healthcare professionals, monitor patient progress, and often spend more time with patients than most other team members. Extended time at the bedside improves the likelihood of detecting subtle physical or emotional changes that might otherwise go unrecognized. Nurses' observations, when consistently communicated with the care team, can significantly influence management decisions. Nurses also provide ongoing education and support, helping patients navigate their treatment plans and maintain realistic expectations.

Physical and occupational therapists contribute by addressing functional limitations and working to reduce long-term disability. The hands-on involvement of these professionals often allows them to detect early signs of changes in limb temperature, color, or range of motion, as well as shifts in mood, affect, or motivation. These observations should be brought promptly to the attention of the managing physician. In addition, therapy assistants and specialized professionals, such as music, art, play, or shop therapists, may offer valuable insights and therapeutic benefits. Each of these team members plays a role in helping patients adapt, cope, and move toward improved quality of life.

Effective treatment of CPS depends on meaningful education, patient-centered communication, and a commitment to incremental progress. While complete pain elimination may not be possible, an interprofessional team approach can consistently improve functional outcomes and overall well-being.
