MASA: What It Measures

Mann Assessment of Swallowing Ability

Quick answer

The MASA measures swallowing function at the bedside in adults, most often after stroke. A clinician rates 24 items covering alertness, cooperation, oral and pharyngeal motor function, and trial swallows, producing a total score that maps to dysphagia severity and aspiration risk categories and guides referral for instrumental assessment.

The MASA turns the clinical swallow evaluation into something scoreable. Instead of a narrative impression, you rate 24 defined items and land on a severity and aspiration-risk category — useful for triage, documentation, and deciding who needs a MBSS or FEES.

MASA at a glance

Full name: Mann Assessment of Swallowing Ability
Publisher: Cengage / Plural (clinical bedside tool)
Domain: Swallowing
Age range: Adults
Administration time: About 15–20 minutes
Format: Clinical bedside swallowing examination with 24 rated items
Score types: Total MASA score, Dysphagia severity rating, Aspiration risk rating

What the MASA measures

Cognitive readiness: alertness, cooperation, auditory comprehension
Respiration and respiratory rate for swallow
Oral preparatory function: lip seal, tongue movement and strength, oral clearance, bolus control
Pharyngeal function signs: palate movement, gag, voice quality, cough, pharyngeal phase timing
Trial swallow performance with graded consistencies

Subtests and sections

Alertness, cooperation, auditory comprehension: Establishes whether the patient can participate safely in an oral trial at all.
Respiration & respiratory rate for swallow: Screens for respiratory compromise that raises aspiration consequence.
Oral motor items: Lips, tongue movement, tongue strength, tongue coordination, saliva management, oral preparation, and oral transit.
Pharyngeal items: Palate elevation, gag reflex, voluntary cough, voice quality, and pharyngeal response.
Bolus trials: Graded consistencies observed for delayed initiation, wet vocal quality, cough, and residue signs.

Where the MASA fits in the dysphagia workup

The sequence exam items expect is: nursing swallow screen, then clinical/bedside swallow evaluation (which the MASA formalizes), then instrumental assessment when clinical signs, medical history, or risk factors warrant it. The MASA is step two. It is designed to tell you how concerned to be and whether imaging is justified — not to characterize the physiology of the swallow.

Silent aspiration is the reason this ordering matters. A meaningful proportion of aspirating patients do not cough, so a clean bedside exam does not equal a safe swallow. Documenting that limitation is standard practice and a recurring theme in ethics and scope-of-practice items.

MASA vs. MBSS/VFSS vs. FEES

The MBSS (also called VFSS) is a fluoroscopic study that visualizes all phases of the swallow including the esophageal sweep, allowing measurement of penetration and aspiration with scales such as the Penetration-Aspiration Scale. FEES uses a flexible endoscope to view the pharynx and larynx directly, tolerates bedside use, has no radiation exposure, and shows secretions well, but is blind during the moment of the swallow. The MASA involves no instrumentation at all and yields risk categories rather than physiologic detail. Each answers a different question; a strong evaluation often uses two of them.

Strengths

Fast, non-instrumental, and repeatable at the bedside.
Structured scoring reduces the variability of narrative clinical swallow exams.
Well studied in acute stroke populations for aspiration-risk triage.
Score changes document progress across an acute stay.

Limitations

Cannot visualize the pharyngeal or esophageal phase — silent aspiration can be missed.
Not a substitute for MBSS/VFSS or FEES when aspiration is suspected.
Validation is strongest in stroke; less established in progressive neurologic disease and head/neck cancer.
Requires clinician training for consistent item scoring.

When clinicians use it

Acute stroke dysphagia screening and severity documentation.
Deciding whether to keep a patient NPO pending instrumental assessment.
Tracking swallow recovery day to day when repeat imaging is impractical.
Supporting diet-texture recommendations alongside instrumental findings.

What the Praxis 5331 asks about the MASA

Know that no bedside exam — MASA included — rules out silent aspiration; the keyed answer for suspected aspiration is an instrumental study.
Recognize wet vocal quality, delayed or absent cough, and prolonged oral transit as clinical signs, not diagnoses.
Understand the SLP's scope in recommending NPO status and instrumental referral.

FAQ

What does the MASA measure?

Adult swallowing function at the bedside across 24 rated items covering alertness, oral motor function, pharyngeal signs, and trial swallows, producing dysphagia severity and aspiration-risk ratings.

How long does the MASA take?

Roughly 15–20 minutes, which makes it practical for acute-care and repeat bedside use.

Can the MASA detect silent aspiration?

No. No bedside clinical exam can reliably detect silent aspiration; a modified barium swallow study or FEES is required when aspiration is suspected.

Who is the MASA designed for?

Adults with suspected dysphagia, with the strongest validation evidence in acute stroke populations.
