A speech-language pathology evaluation will need to be conducted to be conscious vocal use history as well examination of the throat and larynx. This evaluation potentially involves imaging to visualize the vocal cords. Imaging options can include a laryngoscope, videostroboscopy, or laryngeal electromyography. Diagnosis of<unk><unk><unk>  can be difficult due to the variance in symptom presentation and vocal use. Videostroboscopy provides a magnified, slow-motion view of the vocal cords and larynx in action which allows professionals to see any abnormal movement. Videostroboscopy can be used to visualize any swelling of the vocal folds, irritation, or polyps and growth. Occasionally, redness or bumps can be seen on vocal cords which is useful in making a correct diagnosis. Laryngeal electromyography is a test that measures the electrical signals from the voice box muscles (laryngeal muscles) during speaking, breathing, and swallowing. This evaluation is to check if vocal issues are related to any one of the following: partial paralysis resulting in muscle weakness, paralysis resulting in loss of muscle function, and the functionality of the motor unit of the laryngeal muscles. Laryngeal electromyography plays an important role in determining whether or not a nerve problem is the cause of a vocal disorder.
