Thirty patients from a private clinical practice who met the 1990 American College of Rheumatology criteria for fibromyalgia syndrome (FS) were followed prospectively through a brainwave-based intervention known as electroencephalograph (EEG)-driven stimulation or EDS. Patients were initially treated with EDS until they reported noticeable improvements in(More)
Fibromyalgia is characterized by diffuse pain, the origin of which remains obscure. This study explored a phenomenon labeled Diffuse Muscle Coactivation (DMC) as a possible source of pain in fibromyalgia. DMC is defined as an increase from resting levels (tonus) in the electrical activity of any muscle during a movement which does not involve that muscle(More)
Carpal tunnel syndrome (CTS) may be a consequence of increased forearm flexor activity secondary to muscle dysfunction in the neck. Eighteen CTS patients, with an average duration of symptoms of 10 months, were studied. Standardized nerve-conduction studies were administered before and after treatment. Surface-EMG techniques measured sternomastoid and(More)
This study examined the electrical characteristics (Root Mean Square -- RMS and median frequency) of Diffuse Muscular Coactivation (DMC) associated with the tender points of fibromyalgia. DMC is defined as an increase from resting levels (tonus) in the electrical activity of any muscle during a movement which does not involve that muscle and is not part of(More)
Dysregulation in the gamma motoneuron circuitry is proposed as one mechanism to explain the development of trigger point activity in myofascial pain syndrome. Dysregulation in this context is defined operationally as significantly (and functionally) different levels of electrical activity detected in the same muscle on the left and right sides of the body(More)
A biomechanical perspective of the carpal tunnel (CT) is reviewed that lends itself to an understanding of carpal tunnel syndrome (CTS) from a broader pathophysiological perspective than focusing narrowly or solely on nerve disturbance in the extremity. A wider integration of physiological systems in the etiology and maintenance of CTS is proposed that(More)
