The Effects of Voluntary and Involuntary Muscle Recruitment Training on the Strength of Isometric Muscle Contractions

Description: Approximately 50% of individuals who undergo total knee arthroplasty (TKA) fail to achieve a full functional recovery. Current physical therapy practices commonly utilize neuromuscular electrical stimulation (NMES) to passively activate quadriceps muscles. This passive approach does not directly reteach the lost response, but can strengthen the atrophied muscle. Study 1 compared surface electromyography with biofeedback (sEMGBF) with a changing criterion design to NMES alone. Study 2 compared s… more

On the Utility of Surface Electromyography-Based Biofeedback on Rehabilitation from Total Knee Arthroplasty: A Clinical Trial

Description: Knee osteoarthritis affects approximately 25 million adults. In severe cases, total knee arthroplasty (TKA) is the most common solution. TKA is effective at addressing pain and reducing continued degeneration of articular cartilage. However, effective physical therapy (PT) following TKA is vital for a full functional recovery. Despite the importance of PT, half of patients never achieve a full functional recovery. Decreases in proprioceptive feedback, severe atrophy, and pain inhibition all lik… more

Replenishment: A Musical Narrative Inspired by Sleep

Description: The Replenishment cycle contains five works that allude to the experience of sleep, beginning with awake drowsiness and ending with the piece inspired by rapid eye movement (REM) sleep, titled Conceiving Realities. This last piece is an intermedia work composed for chamber ensemble, live painting with biofeedback, computer, and audiovisual processing. This critical essay describes the composition of Conceiving Realities within the context of the Replenishment cycle, followed by a thorough analy… more

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

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 treatme… more

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

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 … more
