Anxiety, Depression, and Sleep Disorders: Their Relationship and Reduction with Neurotherapy

Anxiety, Depression, and Sleep Disorders: Their Relationship and Reduction with Neurotherapy

Date: August 2010
Creator: Fisher, Christopher, Alan
Description: This study investigated the relationship among anxiety, depression, and sleep disturbances and the treatment of these three disorders through neurotherapy. Research suggests that these conditions commonly co-occur in the general population and that central nervous system (CNS) arousal may play a primary role in the development and maintenance of these disorders. Several recent studies suggested that neurotherapy, a biofeedback-based treatment for CNS dysregulation, might be an effective treatment for comorbid conditions, particularly the ones of interest here, depression, anxiety, and sleep disturbances. This investigation used a clinical case-series design to assess pre/post neurotherapy changes on objective measures of anxiety, depression, and sleep and to determine whether changes in anxiety and depression then predict improvements in sleep quality. Data for 23 participants (10 males) were obtained from files of adults (Mage = 40.22 years, SD = 16.20) who received at least 15 neurotherapy sessions (M = 47.83 sessions, SD = 22.23) the University of North Texas Neurotherapy Lab. Matched pair t-tests revealed that symptoms of sleep disturbance, depression, and anxiety showed significant improvements following neurotherapy. Neurotherapy treatment effect sizes generally ranged from moderate to large (d = .414 - .849). Multiple regression analysis found that changes in self-reported anxiety symptoms, but ...

The Effects of Biofeedback and Verbal Feedback on the Training and Maintenance of Diaphragmatic Breathing

The Effects of Biofeedback and Verbal Feedback on the Training and Maintenance of Diaphragmatic Breathing

Date: May 2003
Creator: Armstrong, Earl E.
Description: The purpose of this study was to evaluate the effects of a computer program on the training and maintenance of diaphragmatic breathing. The biofeedback portion was visual computer training and the results were displayed concurrently with participants' breathing responses to monitor display. The verbal feedback portion was praise that was given and recorded when participants responded with predominantly diaphragmatic breathing at the scheduled moment and response instruction that was given when participants responded with predominantly thoracic breathing. The results of this study indicate the computer program's effectiveness needs to be increased by supplementation with verbal feedback.
