During an oral mech exam, which symptom is commonly observed in individuals with ALS?

• A. Audible dry swallow
• B. Hypernasality
• C. Speech hesitation
• D. Rapid speech

Answer: (A)

In individuals with ALS (Amyotrophic Lateral Sclerosis), an audible dry swallow is commonly observed during an oral mechanism examination. This symptom is indicative of dysphagia, or difficulty swallowing, which is a frequent complication of ALS as the disease progresses. As the neuromuscular control of swallowing muscles becomes impaired, patients may struggle to swallow saliva and other substances, leading to the characteristic audible sound when attempting a swallow without adequate saliva or liquid present.

The presence of this symptom reflects the underlying motor neuron degeneration associated with ALS, affecting both voluntary and involuntary muscular control, including the muscles involved in swallowing. Observing this symptom can guide clinicians in assessing the severity of bulbar involvement in ALS patients and in planning appropriate interventions to address swallowing difficulties.
