Summary
This summary is machine-generated.Speech patterns in myasthenia gravis (MG) patients declined over four years, with increased dysarthria and worsening respiratory, phonatory, and articulatory functions, despite stable overall health.
Area Of Science
- Neurology
- Speech-Language Pathology
- Clinical Research
Background
- Myasthenia Gravis (MG) is a chronic autoimmune neuromuscular disease characterized by fluctuating weakness.
- Speech and voice impairments, such as dysarthria, are common but often under-assessed in MG patients.
- Longitudinal studies are crucial to understand the progression of speech deficits in MG.
Purpose Of The Study
- To longitudinally compare speech and voice patterns in myasthenia gravis (MG) patients over four years.
- To correlate speech and voice changes with clinical disease aspects.
- To assess the progression of dysarthria and its impact on respiratory, phonatory, and articulatory subsystems.
Main Methods
- A 4-year longitudinal study involving 10 MG patients (MGG) and 10 controls (CG), matched for age and sex.
- Clinical assessments included Quantitative Myasthenia Gravis (QMG) score, MGFA classification, and MG-QoL.
- Speech tasks were analyzed acoustically and perceptually; acoustic analysis focused on articulatory patterns and vocal quality.
Main Results
- MG participants showed stable health status but increased mild/moderate dysarthria (40% to 90%).
- Significant deterioration was observed in respiration, phonation, and articulation subsystems in MG patients.
- Acoustic analysis revealed declines in speech rate (p=0.047), articulation rate (p=0.007), and increased jitter (p=0.022).
Conclusions
- Myasthenia gravis patients experience speech decline and increased dysarthria over four years.
- Despite stable clinical status, underlying speech subsystems (respiratory, phonatory, articulatory) worsen.
- No significant correlation was found between speech patterns and clinical severity or motor scales in MG.

Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
• Vesicular sounds are soft, low-pitched,...
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:
• Tracheal Deviation: The displacement of the trachea from its normal midline position can be a...
Skeletal muscle relaxants are widely used for muscle paralysis and relieving pain following any muscle injury or stiffness. However, depending on the drug type, they can have adverse effects that range from mild to severe. Usually, nondepolarizing neuromuscular blockers have minimal side effects. For example, drugs like d-tubocurarine, cisatracurium, and rocuronium cause hypotension, whereas drugs like baclofen, when stopped abruptly, can lead to the recurrence of spastic conditions.
