Laryngopharyngeal reflux (LPR) is when stomach acid backflows into the throat and vocal folds.
It can lead to chronic laryngitis/cough and voice disorders (Brown & Shermetaro, 2022). In fact, LPR is present in up to 50% of voice disorders (Belafsky, 2002).
How can speech therapy help in the treatment and management of LPR? In this article you’ll learn:

What Is Laryngopharyngeal Reflux (LPR)?
Laryngopharyngeal reflux is a backflow of stomach acid that moves up through the esophagus and into the pharynx and larynx. It’s a common inflammatory disease and can be acute or chronic (Cui et al., 2024).
This disorder is often misdiagnosed because patients may not present with the more well-known symptoms seen in gastroesophageal reflux disease (GERD; Lechien et al., 2020).
LPR can lead to issues in the larynx and pharynx, including:
- Edema of the pharynx, larynx, false, and true vocal folds
- Thickening of mucus
- Subglottic edema (swelling below the vocal cords)
- Pseudosulcus vocalis (a groove that forms on the free edge of the true vocal fold due to subglottic edema)
- Drying of mucosa/tissues
- Laryngeal granuloma and vocal cord polyps (Cui et al., 2024; Brown & Shermetaro, 2022)
If left untreated, LPR can also lead to dysphonia and vocal fold abnormalities (Lechien et al., 2020).
Symptoms Of LPR
Common symptoms of LPR include:
- Vocal hoarseness
- Globus sensation or ‘lump’ feeling in the throat
- Frequent throat clearing
- Sore throat
- Excessive mucus in the throat
- Nasal drainage (Cui et al., 2024)
- Coughing after eating/lying down or an annoying cough
Some patients also complain of heartburn or regurgitation.
The symptoms of LPR are variable, which can complicate detection and diagnosis. As a result, LPR is often overdiagnosed, underdiagnosed, or misdiagnosed as allergies (Lechien et al., 2020).

How Is LPR Diagnosed?
To be diagnosed with LPR, your patient will need to see a specialist such as an otolaryngologist/laryngologist. The doctor will complete a physical assessment, ask about symptoms, and may complete an instrumental assessment such as a laryngoscopy.
The diagnostic gold standard for testing LPR is the HEMII-pH (hypopharyngeal-esophageal intraluminal impedance-pH monitoring), which is performed by a gastroenterologist.
Speech Therapy LPR Assessment
If you suspect LPR is impacting your patient’s voice, complete a thorough voice assessment and the Reflux Symptom Index (RSI). You’ll find the RDI below, plus a link to a free PDF version.
Reflux Symptom Index (RDI)
The RSI is an assessment tool for patients reporting LPR-like symptoms. It’s a patient-reported outcome measure that can broadly assess the severity of a patient’s LPR (Belsafsky et al., 2002).
“Within the last month, how did the following problems affect you?”
0 = No Problem to 5 = Severe Problem.
- Hoarseness or a problem with your voice.
- Clearing your throat.
- Excess throat mucus or postnasal drip.
- Difficulty swallowing food, liquids, or pills.
- Coughing after you eat or after lying down.
- Breathing difficulties or choking episodes.
- Troublesome or annoying cough.
- Sensations of something sticking in your throat or a lump in your throat.
- Heartburn, chest pain, indigestion, or stomach acid coming up.
A score greater than 13 on the RSI indicates the presence of GERD and/or LPR.
If you suspect our patient may have underlying LPR and/or they score above 13 on the RSI, refer them to an otolaryngologist and/or gastroenterologist. Click for a free RDI PDF offered by Stanford University.
Speech Therapy Laryngopharyngeal Reflux Treatment
- Breathing and relaxation exercises. Breathing and relaxation exercises have been shown to decrease cough and the severity of LPR symptoms (Huestis et al., 2020).
- Voice exercises. Your patient may also benefit from vocal exercises, including relaxation.
- Vocal hygiene. If your patient developed maladaptive vocal behaviors due to LPR, educate on vocal hygiene. See our Vocal Hygiene checklist for a patient handout.
- Avoid acid reflux. Educate patients on how to avoid triggers for acid reflux (Huestis et al., 2020).
- Multidisciplinary care. LPR is a complex disorder, and a multidisciplinary approach is best. Consult with an otolaryngologist and/or gastroenterologist to determine if your patient would benefit from medications to address their LPR.
