Using A Computer Generated Random Number Table

Good Essays

To prevent bias and confounding in treatment assignment, randomization was completed. 10 (5 men, 5 women) participants (see Table 1) were each evaluated in person at the Howard University Speech and Hearing Clinic. Each of which provided written informed consent for participation. Through the use of a computer-generated random number table, each participant was assigned their method of treatment, either via face-to-face or telepractice at another local university speech and hearing clinic. Each participant was 18 years or older and had been previously diagnosed with Primary Muscle Tension Dysphonia (PMTD) by an otolaryngologist. Participants who presented with head and neck cancer, organic lesions, spasmodic dysphonia or other neurological disorders, oropharyngeal dysphagia, respiratory disorders including asthma, or mild MTD were excluded from the study. Also, excluded, were any participants who previously utilized pharmacological treatment or received other voice therapy methods with regards to problems with their voice. Table 1.
