Charcot-Marie-Tooth disease type 1A (CMT1A), the most frequent form of CMT, is caused by a 1.5 Mb duplication on the short arm of chromosome 17. Patients with CMT1A typically have slowed nerve conduction velocities (NCVs), reduced compound motor and sensory nerve action potentials (CMAPs and SNAPs), distal weakness, sensory loss and decreased reflexes. In(More)
Spasticity, a common problem in upper motor neuron lesions, frequently results in uncontrolled involuntary motion that interferes with function. A quantifiable method related to the mechanical output of the muscle is needed to test and improve therapeutic intervention. A sinusoidal displacement of 5 degrees was used to measure elastic and viscous stiffness(More)
We have developed a protocol to measure the progression of disability in patients with Charcot Marie Tooth (CMT) disease, particularly CMT1 over a several year period. Because CMT1 is a chronic disease, the natural history of changes occurring in such a brief period are not well understood, making clinical trials for CMT1 patients difficult to evaluate. We(More)
Recent studies in the psychiatric literature indicate that baclofen has an anxiolytic action in certain psychopathologic conditions. Clinical observation has shown that manifestations of spasticity are increased in anxious individuals, implicating a supraspinal site of mediation for these responses. The purposes of this study were to determine if baclofen(More)
Screen readers can drive braille devices for allowing visually impaired users to access computer environments, by providing them the same information as sighted users. But in some cases, this view is not easy to use on a braille device. In such cases, it would be much more useful to let applications provide their own braille feedback, specially adapted to(More)
Spasticity commonly occurs after a spinal cord injury and is characterized by increased resistance to passive movement of peripheral joints. This study examined the effect of an antispasticity medication on stiffness from the myotatic reflex response generated by passive sinusoidal ankle motion. A repeated measures, multiple base-line, single-subject,(More)
