Swallowing Assessments for Parkinson’s Disease
When deciding whether to do a swallowing screen or a full swallowing assessment, start with a chart review.
If the patient has a swallowing eval order or their chart review has dysphagia red flags (i.e. pneumonia secondary to aspiration), complete a full bedside swallowing assessment.
If not, complete a 3-ounce water test plus an oral motor examination.
If appropriate, also recommend an instrumental swallowing assessment.
Clinical Bedside Swallowing Assessment: Step-by-Step
Sample page from The Evaluation Pack.
1. Current diet
2. Personal Interview
Ask the patient about their swallowing:
- Any recent changes in their swallowing
- When their swallowing problems began
- If and where they feel pain
- If they have trouble eating certain foods
- If and where food feels stuck in their throat or mouth
- Food/liquid avoidance
- Recent weight gain or loss
- What they do that helps their swallowing
3. Oral Motor Examination
Observe strength, range of motion, speed, and symmetry of the following:
- Mandible (CN V):
- At rest
- Open
- Open with resistance

- Tongue (CN XII):
- At rest
- Protrude out
- Protrud out with resistance
- Protrude up
- Protrude up with resistance
- Protrude down
- Protrude down with resistance

4. PO Trials: Liquids and Solids
For each trial, measure and record the amount, cup/spoon/straw use, response, strategies, and duration.
5. Findings
Note any unusual findings or observations.
- Mastication time and amount
- Labial closure completeness
- Oral residue amount and location
- Multiple/suspect piecemeal swallows
- Anterior spillage
- Drooling
- Swallow initiation timeliness
- Laryngeal elevation amount
- Coughing/throat-clearing
- Vocal quality changes
- Respiration changes
- Fatigue
The Mann Assessment of Swallowing Ability (MASA) is a useful tool for quantifying information collected during a bedside swallowing evaluation. Here’s the MASA scoring sheet.
Swallowing Screens for Parkinson’s Disease
The 3-ounce Water Test
The Yale Swallow Protocol is a standardized swallowing screen that includes the 3-ounce water test.
See Yale Swallow Protocol for a free PDF template.
Eating Assessment Tool (EAT-10)
The EAT-10 is a patient-reported outcome (aka questionnaire) that’s recommended by ASHA and has excellent consistency and validity.
Download ASHA’s free EAT-10 PDF template.

Oral Motor Exam
The Motor Speech & Voice Assessment includes an oral motor exam.
To make your own, read How To Do An Oral Motor Exam.
Speech & Communication Assessments for Parkinson’s Disease
If the chart review showed speech or communication red flags, complete the Motor Speech & Voice Assessment, which is available in our shop.
If you’d rather put together your own informal assessment, here’s a step-by-step guide to assessing speech and communication in patients with Parkinson’s disease.
1. Maximum Phonation Time
- Prompt the patient to say ‘ah’ for as long as they can. They should use their normal loudness. Record their time in seconds
- Have them repeat this 3 times. Their MPT is the longest of the 3 trials
- You can compare their MPT with norms
2. Diadochokinetic Rate
Prompt the patient to say the following sounds as quickly and clearly as they can for 15 seconds each. They will repeat each 3 times.
“puh puh puh”
“tuh tuh tuh”
“kuh kuh kuh”
“puh tuh kuh”
You can compare their DDK rate with norms.
3. S/Z Ratio
- Have the patient say ‘sss’ for as long as they can, recording their time in seconds
- Have them repeat this 3 times. Note their longest trial
- Next, have the patient say ‘zzz’ for as long as they can, recording their time in seconds
- Repeat this 3 times, noting their longest trial
- Divide their longest /s/ trial over their longest /z/ trial for their s/z ratio
- You can compare their s/z ratio with norms
4. Habitual Pitch
Sample page from the Motor Speech & Voice Assessment
- Record your patient’s voice
- Ask the patient to repeat after you (see sentences below)
- Measure pitch using a device or software (digital orchestral tuner, Visipitch, pitch pipe, etc.)
- Modal pitch
- Lowest pitch
- Highest pitch
- Average pitch
“Does anyone know how many calories are in a bag of popcorn?”
“My mom meant well but made wrong turns while driving.”
5. Assess Voice Quality
For this portion of the assessment, record another voice sample. Transcribe the patient’s responses, as appropriate, and note your observations
- Word list (either repetition or have the patient read a prepared list aloud)
- Sentences: “Tell me about your speech. Tell me about your voice. What are your speech strengths? Weaknesses?”
- Read paragraph: Ask the patient to read a paragraph aloud (i.e. Rainbow Passage)
- Monologue: Ask the patient about their career, hobbies, family, etc. or to describe a visual scene (i.e. Cookie Theft Picture)
Voice Quality: What To Measure
- Overall Severity: Your overall impression of the voice problem
- Roughness: Vocal irregularity
- Breathiness: Audible air escape in voice
- Strain: Excessive vocal effort
- Pitch: Deviance from a patient’s normal pitch, given their gender, age, and cultures
- Loudness: Deviance from a patient’s normal loudness given their gender, age, and cultures. Including whether too soft or too loud
- Additional Features: such as diplophonia, aphonia, pitch instability, tremor, vocal fry, falsetto, and wet/gurgly quality
Use ASHA’s Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) to measure voice quality.
6. Other Observations During Conversational Speech
- Prosody
- Speech rate (# words per minute during connected speech)
- Breathing pattern (e.g., quick inhale, slow controlled exhale)
- # of words in each breath
- Pitch breaks
- Aphonia
- Phonatory onset of vowels
- Glottal fry
- Vocal tremor
- Resonance
- Intelligibility (% words understood)
- Loudness (using a sound level meter)
Simple rating scale
0= very severely impaired
1= clearly impaired
2= slightly impaired or uncertain
3= within normal limits
7. Complete A Qualitative Questionnaire
The Communicative Effectiveness Index asks caregivers to rate their loved one’s communication effectiveness. Download the free PDF.
Getting caregiver feedback is especially helpful as people with Parkinson’s disease are often unaware of the extent of their communication (and other) issues.
Drooling Assessment for Parkinson’s Disease
The Radboud Oral Motor Inventory for Parkinson’s disease (ROMP) was developed specifically for Parkinson’s disease. The ROMP is a patient-rated assessment with a ‘Saliva’ subsection. Research has found it to be reliable and valid (Kalf, J. G. et al., 2011).
The ROMP is available for clinicians to use with their patients. You can access it in the Guidelines for Speech-Language Therapy in Parkinson’s Disease (scroll down the document to the Appendix).

Complete Follow-Up Assessments (As Needed)
Complete a follow-up assessment if you notice red flags in your patient’s communication or cognition that impact their quality of life, independence, safety, and/or ability to communicate easily and effectively.
For example, if they struggle with word-finding or starting and maintaining a conversation, you may do a full cognitive-linguistic assessment during their first speech therapy session.
Use the Cognitive-Linguistic Assessment available in our shop.
