Effective communication is an essential of everyday life, and stuttering impairs this function. Those who stutter may find effective communication impossible, and severe cases may be rendered almost mute. Clinically significant anxiety figures prominently in the disorder with almost half of those seeking treatment warranting a comorbid diagnosis of social phobia. The adolescent years are generally regarded as a difficult time of life, at which time the potential effects of disfigured speech can be devastating. There has been much research and development of treatments for children and adults who stutter, proven effective treatments are available for those age groups. However, little is known about how to treat adolescents who stutter, and there has been little research and development to find the best treatment-s for this age group. The present proposal is for a randomised, controlled trial of three treatments that have been shown recently to have promise as treatment methods for this age group of patients. The trial will compare (1) a treatment that involves biofeedback muscle activity during speech, (2) a treatment that involves biofeedback of voice box activity during speech, and (3) a variant of a standard treatment that trains the speaker in a new speech pattern. The control group will receive no treatment. The trial extends for a period of 12 months after the subjects are randomly allocated to a treatment group or a control group. The subjects' speech will be assessed in a variety of situations in the clinic and during everyday life. The prime outcome measure will be percentage of syllables stuttered, and secondary measures will be the time required for treatment and how natural the patients sound after treatment. At the conclusion of the trial, the subjects in the control group will be given the treatment that was shown to be most effective.

有效的沟通是日常生活的必需品，而口吃会损害这一功能。口吃的人可能无法进行有效的沟通，严重的甚至会变得几乎哑口无言。临床上显着的焦虑在这种疾病中占据显着地位，几乎一半寻求治疗的人需要被诊断为社交恐惧症的共病。青少年时期通常被认为是人生的艰难时期，此时言语毁容的潜在影响可能是毁灭性的。针对口吃儿童和成人的治疗方法已经进行了大量的研究和开发，事实证明，对于这些年龄段的人来说，有有效的治疗方法。然而，人们对如何治疗青少年口吃知之甚少，也很少有研究和开发来找到适合这个年龄段的最佳治疗方法。目前的提议是对三种治疗方法进行随机对照试验，最近显示这三种治疗方法有望成为该年龄段患者的治疗方法。该试验将比较（1）一种涉及言语过程中生物反馈肌肉活动的治疗方法，（2）一种涉及言语过程中声带活动生物反馈的治疗方法，以及（3）一种以新的言语模式训练说话者的标准治疗方法的变体。对照组不接受任何治疗。受试者被随机分配到治疗组或对照组后，试验将持续 12 个月。受试者的言语将在诊所和日常生活中的各种情况下进行评估。主要结果指标是口吃音节的百分比，次要指标是治疗所需的时间以及治疗后患者声音的自然程度。试验结束时，对照组的受试者将接受被证明最有效的治疗。
