Muscular spasm, the etiology of which remains elusive, has been difficult to control. The authors, therefore, proposed selective restraint of forced contractions by a closed-loop circuit. In four dogs, the strap (n = 6) and thyroarytenoid (n = 4) muscles were submitted to tetanic contractions via bipolar supramaximal stimulation (30 Hz, 6 mA, 0.5 msec) of(More)
OBJECT The literature on abdominal and general surgery-related complications following anterior lumbar interbody fusion (ALIF) is scant. In this retrospective review of 60 patients in whom ALIF was performed at their institutions between 1996 and 1998, the authors detail the associated complications and their correlation with perioperative factors. The(More)
Coordinated electronic pacing of implanted nerve pedicles into paralyzed laryngeal muscles has allowed selective dynamic control of abduction, adduction, and elongation of the vocal cords. Modifications of the original circuit in a cervical muscle model has added fine tuning to basic "all-or-none" pacing. Rehabilitation of phonation illustrated the(More)
A fully reliable means of rehabilitating patients with bilateral vocal cord paralysis has not yet been developed. In order to improve upon existing solutions to this problem, the authors have recently described a laryngeal pacemaker, initially tested through stimulation of a cross-over nerve-muscle pedicle from one sternohyoid muscle to the other in the(More)
We present the results of a combined experimental and numerical study of flow separation in the unsteady, two-dimensional, rotor-oscillator flow. Experimentally-detected material spikes are directly compared to separation profiles predicted from numerical shear-stress and pressure data, using a recent kinematic theory of unsteady separation. and(More)
The neuroanatomical structures that approximate the bony pedicles of the lumbar spine allow little room for technical error or compromise of the bone during pedicle screw insertion. Currently available neurophysiological monitoring techniques detect compromised bone and nerve root injury after it occurs. The purpose of this prospective study is to evaluate(More)
A high order particle-source-in-cell (PSIC) algorithm is presented for the computation of the interaction between shocks, small scale structures, and liquid and/or solid particles in high-speed engineering applications. The improved high order finite difference weighted essentially non-oscillatory (WENO-Z) method for solution of the hyperbolic conservation(More)
Toxoplasmosis and lymphoma are the two most common causes of intraparenchymal cerebral mass lesions in patients with acquired immunodeficiency syndrome (AIDS). The clinical and radiographic features of the intracranial lesions have been well described. Because of the high frequency of toxoplasmosis in the AIDS population, common therapy for patients(More)
We have recently demonstrated the feasibility of artificial agonist/antagonist coupling between intact facial and reinnervated strap muscles in the rabbit. The present study broadens this principle to involve bi-level cross-facial innervation. After severing the facial innervation unilaterally in four dogs, a nerve pedicle from a cervical motor nerve was(More)
