Purpose and Suitability

Clarify what the person means by swallowing difficulty, investigate safety and decide what further assessment is needed.

Dysphagia: Difficulty swallowing. Globus: A lump or foreign-body sensation in the throat, distinct from impaired passage of food.

The clinician distinguishes mouth/throat swallowing difficulty from oesophageal symptoms and reviews safety, nutrition and examination findings. A specific task inconsistency can contribute to a formulation, but a normal bedside examination cannot exclude aspiration or other swallowing disease. [1][2]

Anatomy and Physiology

Swallowing moves material through the mouth, throat and oesophagus while protecting the airway. Oral preparation, throat transfer and oesophageal passage answer different clinical questions. [2]

Aspiration: Material entering the airway below the vocal folds. Bolus: The portion of food or liquid being swallowed.

A comfortable-looking swallow or absence of coughing cannot establish absence of aspiration; it can occur silently. [2]

Preparation and Safety

Review the existing intake plan and explain the assessment before offering anything by mouth. Agree communication and stop signals, comfortable supported positioning and needed assistance. Consent to clinical assessment is separate from consent to recording or teaching use.

Only the responsible clinician selects whether oral trials are appropriate and which consistencies and quantities to use. Do not offer a default water challenge, an unapproved texture or repeated trials to provoke difficulty. Stop and reassess when safety or tolerance changes. These are teaching safeguards, not a universal test protocol.

Performing the Assessment

Establish whether the complaint is dysphagia, globus, choking fear, pain, regurgitation or another sensation. Document onset, course, consistency effects, nutrition, hydration and respiratory consequences.
Screen for urgent or progressive features and examine relevant cranial-nerve, voice, respiratory and neurological function.
Conduct a clinical swallowing evaluation using only consistencies and quantities that are justified and safe for the person. Observe oral preparation, swallow timing, laryngeal signs, voice change and recovery.
Arrange FEES, videofluoroscopy, endoscopy, imaging or other investigation when needed to assess safety, physiology or an identified differential.
Compare reported difficulty, observed performance and instrumental findings. Look for a coherent positive functional pattern, but do not infer functional dysphagia only because structural testing is normal.
Consider structural disease, neurological dysphagia, reflux, eosinophilic disease, medication effects, pain and avoidant/restrictive food intake according to the presentation.
Explain the conclusion and provide an eating, drinking and treatment plan. Reassess if nutrition, respiratory status or symptom pattern changes.

This retains the original seven-step educational outline; it is not a validated diagnostic score. [1][2]

Cross-task swallowing comparison

Swallowing behaviour is compared across clinically appropriate contexts, including spontaneous and requested actions. A reproducible mismatch may be informative. Different textures or volumes are only used within an assessed safety plan; variability is not a standalone FND sign. [1]

Record the actual comparison, posture, assistance, observed response and the person’s experience. Differences in texture, volume or fatigue change task demands; document them rather than attributing every change to attention.

Interpreting Findings

Potentially supportive: A specific reproducible mismatch may contribute to the formulation after safety, anatomy and competing explanations are considered. Explain exactly why it is informative.

Not demonstrated: No discrepancy in this sample supplies no positive functional finding from that comparison; it does not decide every possible cause.

Indeterminate: Unsafe intake, incomplete sampling or an unclear relationship between symptom and task limits interpretation. Document what remains unanswered and choose the next assessment accordingly.

A normal bedside observation does not clear all food and drink or exclude aspiration. See instrumental assessment. One successful swallow does not establish adequate nutrition, meal endurance or independence; ask about these separately. [2]

Explaining the Result

Authored example, not a patient quotation:

“We have described where the difficulty seems to occur and what we observed today. I will explain which findings support the diagnosis, what still needs checking and what your eating and drinking plan should be while we do that.”

Avoid promising that an improved swallow during assessment will transfer immediately to every meal.

Evidence and Limitations

The clinical outline draws on expert consensus and general swallowing guidance. It has no assigned sensitivity, specificity or universal cutoff for FND. A test of safety and a positive functional formulation are different judgments. [1][2]

Do not substitute a stress history or normal structural results for symptom-specific reasoning. The oesophageal criteria page describes a separate framework. Daily-impact questions are editorial prompts, not a validated disability scale.

Media and Accessibility

The safest contribution is a clinician-led explanation using a swallowing diagram. If instrumental media is available, use an existing, de-identified and specifically consented FEES or videofluoroscopy segment to identify anatomy and the question the study answers.

Do not ask a participant to swallow a chosen food, large bolus or difficult texture for public filming. Do not imply that a normal-looking swallow in one clip proves every meal is safe. The written page and narration must distinguish globus from dysphagia and include the need for individual safety guidance.

Provide clear labels, descriptive alternative text, captions and a transcript. No images or recordings are supplied.
