What is one symptom of laryngeal hyperkinesia?

• A. Fluent speech
• B. Voice is clear and stable
• C. Shaky or tight voice
• D. Excessively nasal resonance

Answer: (C)

Laryngeal hyperkinesia is characterized by excessive muscle contractions in the larynx, which leads to distinct voice qualities. One key symptom of this condition is a shaky or tight voice, resulting from the involuntary and excessive movement of the vocal folds. This leads to a lack of smoothness in voice production, causing the voice to sound shaky or tense.

In contrast to the correct option, the other choices do not align with the symptoms of laryngeal hyperkinesia. Fluent speech and clear and stable voice typically imply normal laryngeal function and do not reflect the dysregulation seen in hyperkinesia. Excessively nasal resonance suggests a problem with airflow through the nasal passages, which is separate from the symptoms associated with laryngeal hyperkinesia and might point to other conditions such as resonance disorders or structural issues. Thus, the correct identification of a shaky or tight voice as a symptom accurately captures the essence of what individuals with laryngeal hyperkinesia experience.
