Positive clinical signs that rule in functional neurological disorder are grounded in internal inconsistency and incongruence with known disease patterns, allowing a confident diagnosis at the bedside rather than one of exclusion. In routine neurology assessment, these signs are elicited by demonstrating normal automatic performance of a movement that appears weak or abnormal when tested volitionally, or by showing symptom change with distraction, loading, or task modification.
For limb weakness, the hoover sign is a cornerstone: apparent weakness of voluntary hip extension on the “affected” side normalizes when the contralateral hip flexes against resistance, indicating preserved automatic motor output. A related maneuver is the hip abductor sign, where weak abduction improves when the opposite leg abducts against resistance. Give-way (collapsing) weakness, in which force initially rises and then suddenly yields in a nonphysiologic way, and variable drift without a pyramidal pattern, further support functional limb paresis when they occur alongside normal coordination during automatic tasks (for example, walking on heels or toes) and preserved rapid alternating movements.
In functional tremor and other hyperkinetic phenomena, tremor entrainment is highly informative. When the patient is asked to tap a steady rhythm with the unaffected limb, a functional tremor will often change frequency to match the imposed rhythm, become irregular, or stop altogether. Distractibility is another hallmark: mental arithmetic, conversation, or contralateral ballistic movements can dampen or abolish the tremor. Additional supportive features include variability in frequency and axis, an increase in amplitude with light loading rather than the expected attenuation, and the co-contraction sign, where antagonist muscles contract simultaneously during the movement. Sudden onset, spontaneous remissions, and marked day-to-day fluctuation also align with a functional mechanism.
Gait and balance provide further opportunities to identify rule-in features. Functional gait patterns may include knee buckling without true falls, a cautious “walking-on-ice” pattern with a narrow base but intact balance on challenging maneuvers, or dramatic sway that improves with distraction or when walking backward. Inconsistent performance across tasks—such as poor single-leg stance during formal testing but stable tandem or backward walking—reinforces internal inconsistency. Exaggerated sway with eyes open that diminishes with conversational distraction is likewise supportive.
Sensory findings favoring a functional presentation include nondermatomal or sharply demarcated loss that respects the midline in a way that peripheral or central lesions typically do not, and variability across repeated examinations. Vibration “splitting” at the sternum or forehead—where vibration applied at the midline is perceived only on the “good” side yet is felt symmetrically when the tuning fork spans both sides—illustrates internal inconsistency. Functional visual complaints may manifest as tubular visual fields that maintain the same diameter at different testing distances, another incongruent pattern.
Paroxysmal episodes consistent with functional (psychogenic) nonepileptic seizures also have positive semiologic markers: ictal eye closure with resistance to passive opening, side-to-side head movements, asynchronous limb thrashing, pelvic thrusting, vocalization with fluctuating awareness, and prolonged duration with a waxing-and-waning course. Rapid recovery without a postictal phase and recall of events can further support the impression when considered alongside other clinical signs.
Across presentations, reproducibility of these signs within the same visit—such as consistent response to distraction or task interference—and their presence across multiple body regions strengthen confidence in the diagnosis. Careful documentation of exactly how the sign was elicited, the immediate change observed, and the contextual factors that modified symptoms ensures that the findings are transparent and can be re-demonstrated in future assessment and during multidisciplinary review as part of a rigorous differential diagnosis.
Structured history and examination
A structured approach begins with a collaborative history that privileges specificity and chronology. Ask the patient to map when symptoms first appeared, whether onset was sudden or gradual, and how the pattern has evolved over hours, days, and weeks. Pin down short-term variability within the same day and during different contexts, such as at work versus at home, during focused tasks versus casual activities. Clarify which actions make symptoms better or worse, noting particularly whether distraction, task switching, or engrossing activity leads to improvement, as this can foreshadow positive clinical signs later in the examination and support a rule-in diagnosis.
Timing and triggers provide essential context. Document precipitating events such as an injury, acute pain episode, infection, anesthesia, a difficult medical encounter, sleep loss, or marked stress, while avoiding assumptions about causality. Ask what the patient was doing minutes before the first episode and in the days surrounding it. Explore perpetuating factors—ongoing pain, hypervigilance to bodily sensations, disability-related deconditioning, and sleep disturbance—and protective factors like routines that reliably lessen symptoms. This 4P framework (predisposing, precipitating, perpetuating, protective) helps structure the assessment and guides individualized rehabilitation plans.
Variability across tasks should be captured in detail. Elicit examples of everyday automatic functions that are better than formal, effortful performance, such as steadier handwriting when filling a form compared with spiral drawing, or stronger grip while carrying a shopping bag than during strength testing. Record whether symptoms fluctuate with divided attention, conversation, or mental arithmetic, and whether feared tasks (stairs, crowds, narrow spaces) disproportionately aggravate disability. These history elements mirror the inconsistency observed on examination and interface directly with the differential diagnosis.
Co-occurring symptoms are common and relevant to treatment planning. Screen for migraine, chronic pain, irritable bowel or bladder symptoms, dizziness and orthostatic intolerance, fatigue, sleep problems, cognitive fog, and dissociative experiences. Ask about joint hypermobility, frequent sprains, and autonomic symptoms such as palpitations or heat intolerance. Review prior neurology evaluations and imaging, current and previous medications (including antiseizure drugs and benzodiazepines), and adverse effects that may worsen fatigue or balance. A brief mood and anxiety screen can be helpful, but avoid conflating emotional state with causation; many patients report symptoms irrespective of mood changes.
For paroxysmal events, obtain a precise eyewitness account or smartphone video when available. Clarify duration, onset pattern, triggers, responsiveness, eye position and closure, movements of the head and pelvis, and injuries. Ask about recovery time, post-event fatigue, tongue biting location, and urinary incontinence, noting that waxing-and-waning episodes with retained awareness or rapid recovery may suggest a functional mechanism. Distinguish presyncopal prodromes (lightheadedness, visual graying) from events starting from stillness. Document frequency, clustering, and any stimulus sensitivity, as this will guide both examination maneuvers and safety planning.
Before formal testing, observe spontaneous behavior from the waiting area to the clinic room: rising from a chair, phone use, donning shoes, and arm swing while walking. Naturalistic tasks often reveal preserved automatic function that contrasts with later volitional testing. During the interview, note consistency of speech, facial expression, and limb posture, and whether symptom intensity changes with narrative engagement. These observations are part of the neurology assessment and should be recorded as objective findings.
Arrange the neurological examination to demonstrate rule-in features early. Begin with vital signs and general inspection, then proceed to motor testing with attention to internal inconsistency. When limb weakness is reported, include the Hoover sign and hip abductor sign, assess for give-way weakness, and compare strength across repeated trials with varying instructions. Look for preserved rapid alternating movements, normal coordination in automatic tasks, and improvement during contralateral activation. Grade strength in a standard fashion while documenting immediate changes with distraction or task interference.
In suspected functional tremor or jerky movements, apply structured probes: tremor entrainment with metronome or contralateral tapping, distraction through cognitive tasks, and light loading to assess amplitude behavior. Examine for co-contraction by palpating agonist and antagonist muscle groups during movement. Evaluate variability in frequency and axis across tasks such as posture holding, writing, and drawing. Record the exact conditions under which frequency shifts, suppression, or irregularity occur, as these provide concrete, reproducible clinical signs for patient education and multidisciplinary review.
Sensory testing should look for patterns that are incompatible with neuroanatomy and that vary with attention. Map nondermatomal loss, midline splitting, and side-to-side differences that change across repeated exams. Use a tuning fork to test vibration at the midline sternum or forehead, noting perceived “splitting” that resolves when the fork spans both sides simultaneously. For visual complaints, assess for tubular fields that maintain the same diameter at different distances, and consider optokinetic stimuli or saccadic tasks to gauge functional visual performance.
Gait assessment benefits from graded complexity. Observe initiation, base of support, knee stability, and arm swing during forward walking, then test backward and tandem walking, dual-task walking with conversation or serial subtraction, and turns. Note knee buckling without falls, exaggerated sway that lessens with distraction, or a narrow-based “walking-on-ice” pattern with surprisingly intact balance during challenging maneuvers. Document which additions (backward walking, cognitive load) improve stability, as this directly illustrates internal inconsistency.
Functional communication during the examination is part of best practice. Narrate observations in neutral, descriptive language while demonstrating changes in real time—for example, showing how hip extension normalizes during contralateral hip flexion, or how tremor frequency matches a tapped rhythm. Invite the patient to feel muscle activation or observe their own movement on video, when appropriate and consented. This approach supports understanding, enhances engagement with rehabilitation, and anchors the diagnosis in observable physiology rather than inference.
Comprehensive documentation ties the history to the examination. Record the exact maneuvers used, the context in which symptoms changed, and any measurable parameters such as rhythm speed, step counts, or strength grades across trials. Note coexisting neurological conditions when present, as FND can coexist with structural disease, and outline which findings are attributable to each. This transparent record facilitates continuity across clinicians, assists with multidisciplinary planning, and ensures that the positive evidence base for the diagnosis is clear and reproducible.
Differential diagnosis and red flags
The differential diagnosis should be anchored in rule-in evidence while remaining alert to patterns that demand alternative explanations or indicate comorbidity. Functional neurological disorder can coexist with structural, degenerative, and systemic disease; mapping which symptoms are supported by positive clinical signs and which follow neuroanatomy avoids all-or-nothing thinking. Red flags include progressive, stereotyped deficits that do not vary with attention or task; persistent objective upper motor neuron findings; new cognitive or systemic features; and safety-critical symptoms such as syncope with exertion or rapidly worsening gait instability.
For limb weakness, distinguish internal inconsistency from fixed neuroanatomical patterns. A pyramidal distribution with spasticity, hyperreflexia, clonus, and a Babinski sign points to corticospinal tract disease, whereas dermatomal pain, focal myotomal weakness, and reduced reflexes suggest radiculopathy. A clear sensory level, Lhermitte phenomenon, saddle anesthesia, or new sphincter dysfunction raises concern for myelopathy. Wasting and fasciculations indicate lower motor neuron pathology. By contrast, a positive Hoover sign, variable or give-way strength without atrophy, preserved rapid alternating movements, and normal tone align with a functional mechanism. When fatigable diplopia, ptosis, or bulbar symptoms accompany apparent weakness, consider neuromuscular junction disorders; variability in these conditions is linked to effort and time rather than distraction or contralateral activation.
In movement phenotypes, functional tremor is supported by distractibility and tremor entrainment, as well as variability in axis and frequency across tasks. Red flags for alternative diagnoses include parkinsonian features such as bradykinesia with decrement, cogwheel rigidity, rest-predominant tremor that persists through distraction, and reduced arm swing. Cerebellar tremor and ataxia are suggested by intention worsening near the target, dysmetria, scanning speech, ocular dysmetria, and truncal instability that does not improve with conversation or dual-tasking. Jerky movements warrant consideration of dystonia (fixed posturing, geste antagoniste) or myoclonus; prominent encephalopathy, stimulus-sensitive generalized jerks, or metabolic triggers should prompt a broader workup.
For paroxysmal episodes, features favoring epileptic seizures include stereotyped semiology across attacks, nocturnal occurrence from sleep, prominent postictal confusion, cyanosis, and lateral tongue lacerations. Todd’s paresis after an event should trigger careful reappraisal for structural or epileptic etiologies. Functional (psychogenic) nonepileptic seizures are supported by waxing-and-waning intensity, prolonged duration, ictal eye closure with resistance to opening, asynchronous limb movements, pelvic thrusting, and rapid recovery without postictal confusion when considered with other positive signs. Differentiate convulsive syncope by a clear presyncopal prodrome (lightheadedness, visual graying), pallor, brief loss of consciousness with few jerks, and quick orientation on recovery; exertional syncope, family history of sudden death, or known structural heart disease are red flags requiring urgent cardiac evaluation.
Sensory and visual complaints require attention to anatomical plausibility. Length-dependent loss with reduced ankle reflexes and distal neuropathic pain suggests peripheral neuropathy, whereas a distinct sensory level or bilateral hand and trunk involvement points toward a myelopathic or central process. Painful eye movements, red desaturation, a relative afferent pupillary defect, or optic disc swelling raise concern for optic neuritis or other primary ocular pathology. Functional sensory patterns include midline splitting, nondermatomal borders, variability across repeated tests, and tubular visual fields that remain the same diameter at different distances; the presence of ocular motor palsies, internuclear ophthalmoplegia, or persistent diplopia are red flags for central causes.
Gait disorders require separation of functional patterns from cerebellar, sensory, vestibular, or frontal etiologies. Functional gait often shows knee buckling without falls, a narrow-based “walking-on-ice” strategy, and improved performance during backward or dual-task walking. Red flags for alternative disease include a wide-based ataxic gait with impaired tandem walking that worsens under distraction, inability to sit or stand unsupported, severe sensory ataxia with a markedly positive Romberg sign, direction-fixed spontaneous nystagmus with abnormal head-impulse testing, or progressive falls without fluctuation. Coexisting orthopedic or peripheral neuropathic contributors should be considered when pain and proprioceptive loss are prominent.
Autonomic and pain syndromes can mimic or complicate FND presentations. Objective orthostatic hypotension, marked heart rate increase on standing with reproducible orthostatic symptoms, or syncope warrants evaluation for orthostatic disorders rather than attributing dizziness solely to a functional mechanism. Complex regional pain syndrome is suggested by temperature or color asymmetry, edema, sweating changes, and trophic alterations consistent with accepted criteria; dramatic motor fluctuation and internal inconsistency in strength may still indicate a functional overlay. Small fiber neuropathy, endocrine disorders, and medication effects can amplify sensory and autonomic complaints and should be addressed within the differential.
Systemic red flags that should prompt broadened investigation include fever, weight loss, immunosuppression, malignancy history, new severe or thunderclap headache, meningismus, encephalopathy, rapidly progressive focal deficits, new-onset symptoms in older age, pregnancy or postpartum state, and toxin or medication exposures. Metabolic and nutritional mimics such as thyroid dysfunction, vitamin B12 deficiency, electrolyte disturbance, and hepatic or renal failure may produce fluctuating neurological symptoms without the internal inconsistency characteristic of FND.
A practical approach is to document the rule-in evidence alongside any discordant features and to let red flags drive targeted testing. When positive clinical signs convincingly support the diagnosis and no red flags are present, extensive investigations are rarely helpful; when red flags emerge or comorbidity is likely, the neurology assessment should be revisited, attributing each symptom to the most parsimonious cause and updating the differential diagnosis accordingly.
Role of ancillary testing
Ancillary testing should complement, not replace, the rule-in approach established by positive clinical signs. The purpose is to corroborate the bedside impression, screen for comorbidity, and address red flags identified during the neurology assessment. Tests are most useful when they help explain why symptoms vary, demonstrate intact neural pathways despite impaired voluntary control, or document alternative causes where the differential diagnosis remains open.
Neuroimaging is guided by clinical context. Brain and spinal MRI are appropriate when the history or examination suggests structural disease, there are progressive focal deficits, new severe headache, optic neuropathy, myelopathy features, or older age at onset. In typical presentations with robust rule-in signs and no red flags, repeating normal scans adds little and risks incidental findings that complicate the diagnosis. Dopamine transporter imaging and other nuclear studies are rarely needed; reserve them for carefully selected cases where parkinsonism is strongly suspected despite inconclusive examination.
For paroxysmal events, capturing a habitual spell on synchronized video-EEG remains the gold standard. Typical features of functional (psychogenic) nonepileptic seizures can then be correlated with an EEG that lacks ictal epileptiform activity and shows preserved background. When inpatient monitoring is not immediately feasible, ambulatory EEG and high-quality smartphone videos from witnesses can narrow the differential. Postictal serum prolactin and creatine kinase have limited utility; elevations may occur after generalized tonic–clonic seizures but are not specific and should not be used in isolation to make or refute a diagnosis.
Surface EMG and accelerometry are particularly helpful for functional tremor and jerky movements. These tools can quantify variability, document co-contraction of antagonist muscles, and demonstrate tremor entrainment—frequency shifting to match an imposed rhythm—under standardized tasks. Coherence analysis may show coupling between the tremor and contralateral tapping that would not occur in organic tremor. Lightweight limb loading often paradoxically increases amplitude in functional tremor, a measurable behavior that can be shown to the patient to support understanding of the mechanism.
Electrodiagnostic studies for weakness are targeted. Nerve conduction studies and needle EMG can reveal neuropathy, radiculopathy, or motor neuron disease when suspected from the examination, but they are commonly normal in functional limb paresis. When performed, normal motor unit recruitment with preserved activation across tasks supports intact peripheral pathways, aligning with bedside demonstrations such as the Hoover sign. Transcranial magnetic stimulation to assess corticospinal conduction can be normal and is rarely required outside subspecialty centers.
Visual and sensory complaints benefit from focused ophthalmic and neuro-otologic evaluation when indicated. Automated or Goldmann perimetry may reveal tubular or spiral fields that remain the same diameter at different distances, patterns inconsistent with optic tract or retinal disease. Optical coherence tomography and visual evoked potentials can identify optic neuropathy when suspected; normal findings in the context of incongruent fields support a functional mechanism. For dizziness, vestibular testing (video head impulse, caloric, and vestibular evoked myogenic potentials) often returns normal in functional presentations and in persistent postural-perceptual dizziness; abnormalities should match the history and examination rather than appear in isolation.
Autonomic and syncope evaluations are reserved for appropriate triggers and red flags. Orthostatic vital signs at the bedside are a low-burden screen. Tilt-table testing can clarify neurally mediated syncope, orthostatic hypotension, or postural tachycardia syndrome when presyncopal prodromes, exertional triggers, or injury risk are present. Importantly, tilt testing may provoke functional episodes; careful review of semiology and hemodynamic data together prevents misattribution.
Wearables and home technologies can add practical, low-cost data. Time-stamped smartphone videos of events, heart rate trends from consumer devices, and brief activity logs around spells help correlate physiologic states with symptoms. In functional tremor, short recordings during imposed tapping tasks can capture frequency shifts that mirror clinic findings, reinforcing the rule-in evidence base.
Laboratory studies are selective rather than routine panels. Screen for mimics suggested by the history—thyroid dysfunction, vitamin B12 deficiency, autoimmune or infectious markers, electrolyte disturbances—when systemic features or red flags are present. Repeating broad normal labs in typical FND does not improve outcomes and can inadvertently increase health anxiety.
Gait and balance instrumentation can be informative in complex cases. Force plate or instrumented gait analysis may show normal or exaggerated sway with preserved protective responses, contrasting with the fixed patterns of cerebellar or sensory ataxia. Such data are most useful when they directly illustrate internal inconsistency already observed at the bedside and when they guide targeted physical therapy.
Neuropsychological testing is helpful for characterizing cognitive complaints and planning rehabilitation rather than for proving or disproving FND. Profiles often show fluctuating attention and executive control with variable task engagement; performance validity measures contextualize results without implying volitional control. Feedback should link findings to practical strategies for pacing, attention management, and graded return to activities.
Functional neuroimaging research methods, such as task-based or resting-state fMRI, are not diagnostic in individual patients and should not be used to determine etiology in the clinic. Similarly, specialized evoked potential paradigms or startle testing are generally confined to research or niche indications.
Across modalities, the key is to integrate results with bedside evidence. A normal or nonlocalizing test in the presence of robust positive clinical signs supports a functional mechanism, while discordant abnormalities should track with symptoms and anatomy before altering the working diagnosis. Document how each study refined the differential diagnosis, whether it revealed comorbidity, and how it will change treatment, avoiding cascades of low-yield investigations.
When discussing the test plan with patients, frame studies as tools to map coexisting problems, address safety concerns, and demonstrate reversible physiology, not as a search for a missed disease. Sharing concrete outputs—video-EEG traces during a captured event, EMG charts showing tremor entrainment, or normal vestibular responses despite severe subjective dizziness—can enhance acceptance of the diagnosis and motivate engagement with rehabilitation.
Communicating the diagnosis
Begin by naming the condition clearly and early, then immediately anchor the explanation in the positive evidence found during the visit. “Today’s findings point to a functional neurological disorder,” followed by, “we can see this because of the way your symptoms changed with distraction and task switching,” positions the diagnosis as evidence-based. Use neutral, descriptive language and relate each observation directly to what the patient felt or saw: “When you pushed down with the left leg, it seemed weak, but with the right leg lifting, your left hip extension switched on strongly; that pattern, called the Hoover sign, tells us the pathway is intact even though voluntary control is disrupted.”
Demonstration strengthens understanding. Recreate key clinical signs together if fatigue allows. Invite the patient to feel muscle activation or watch a short replay on their phone if a recording was made. For tremor, show how tapping a rhythm with the other hand changed the tremor frequency—tremor entrainment—and explain: “This shift means the system is responsive and modifiable, which is good news for treatment.” Grounding the message in visible physiology reframes uncertainty into a concrete mechanism.
Use simple, nondualist language to describe how symptoms arise: “Your nervous system is functioning, but its control networks are stuck in a protective, misfiring pattern. That’s why symptoms are real and can be severe, even though scans and routine tests can be normal.” Avoid implying intent or blame. Replace phrases like “it’s psychological” or “nothing is wrong” with “the problem is in how the brain is working, not in structural damage,” and emphasize that the diagnosis is based on what was found, not on ruling everything else out.
Normalize the condition without minimizing it. Brief prevalence and prognosis statements can help: “FND is common in neurology clinics and is treatable. People improve by retraining automatic movements and building confidence in safe function.” Pair this with a concrete first step to convey momentum: “We will start with a physiotherapy program that uses the same cues that helped your leg strength normalize here.”
Adopt an ask–tell–ask approach to keep the conversation collaborative. Ask what the patient already thinks is happening and what they fear most. Tell the core message in small chunks tied to the observed clinical signs. Ask the patient to reflect back what they heard: “Just to be sure I explained this well, can you put in your own words what we saw and what FND means?” Clarify misconceptions immediately and invite questions about terminology, causes, and recovery.
Address common concerns directly. For “Are you saying it’s all in my head?” respond, “The symptoms are in the nervous system and are not imagined. They are genuine and came from patterns that we can see and change.” For “Will this mean I’m missing another disease?” say, “We considered the differential diagnosis carefully. Your examination had rule-in signs for FND, and no red flags for other conditions. If anything changes—like new constant weakness, new vision loss, fever, or progressive decline—contact us, and we will reassess promptly.” Safety-netting preserves trust while reinforcing confidence in the current plan.
Link the mechanism to rehabilitation. “Because your movement improves automatically when attention shifts, therapy will focus on building automatic control and reducing over-monitoring.” Specify components: graded physiotherapy emphasizing normal movement patterns, pacing for fatigue, occupational therapy for functional tasks, and, when relevant, psychological therapies aimed at symptom management, not at proving causation. Stress that treatment targets the nervous system’s control and can proceed even when the origin of symptoms is unclear.
Tailor communication to phenotype. For limb weakness, highlight inconsistency and preserved automatic function seen during walking or contralateral activation. For tremor or jerks, emphasize variability, distractibility, and entrainment, connecting these to retraining strategies and sensory tricks used in therapy. For functional seizures, explain that episodes are dissociative events with a recognizable pattern, that they are not epileptic, and that treatment focuses on trigger recognition, grounding techniques, and specialized therapy; provide clear guidance on driving, safety plans, and when to seek urgent care.
Validate coexisting problems and comorbidity without diluting the message. “Migraine and pain can amplify symptoms; we will treat those alongside FND.” If ancillary tests were done, frame results as supportive context: “Your video-EEG captured a typical event without epileptic activity, which aligns with today’s examination,” or “MRI was normal, consistent with a functional mechanism.” This integrates the neurology assessment with test findings and avoids implying that normal tests negate suffering.
Provide written resources and a pathway. Offer a brief summary letter that names the diagnosis, lists the positive signs demonstrated in clinic, outlines the treatment plan, and includes reputable patient education links and emergency guidance. Encourage patients to share the letter with family, employers, and therapists to align expectations and reduce repeated explanations that can be exhausting.
Include family or caregivers when possible. Invite them to observe demonstrations and practice supportive responses that avoid inadvertently reinforcing symptoms, such as shifting attention to an external task rather than repeatedly checking the affected limb. Align on practical goals: returning to school or work with accommodations, resuming driving when criteria are met, and pacing activities to avoid boom–bust cycles.
Plan follow-up with clear milestones. “By our next visit we’ll aim for walking two blocks without symptoms by using the same cueing strategies that helped today.” Define what improvement looks like—greater time in valued activities, fewer events, smoother movement—rather than only symptom counts. Anticipate fluctuations and frame them as expected during retraining, not as failure.
When skepticism or prior negative experiences are prominent, acknowledge them and separate the message from past labeling. “It makes sense you’re cautious after many appointments. What is different today is that we observed features that positively identify FND and we can show how they change. That gives us a clear target for treatment.” Offer a second-look visit or a joint session with physiotherapy or psychology to consolidate understanding.
Document communication thoroughly. Record the rule-in evidence shown to the patient, their understanding using teach-back, the agreed plan, and safety-netting instructions. Clear documentation supports continuity across clinicians and reinforces that the diagnosis rests on observable, reproducible findings tied to a practical rehabilitation strategy.
