OBJECTIVES To test the efficacy and acceptance of a footdrop stimulator controlled by a tilt sensor. METHODS A nonrandomized, test-retest study of 26 subjects with footdrop of more than 1 year's duration, resulting from various central nervous system disorders, was performed in 4 centers for at least 3 months. Speed of walking in a straight line, speed(More)
BACKGROUND Stimulators applying functional electrical stimulation (FES) to the common peroneal nerve improve walking with a foot drop, which occurs in several disorders. OBJECTIVE To compare the orthotic and therapeutic effects of a foot drop stimulator on walking performance of subjects with chronic nonprogressive (eg, stroke) and progressive (eg,(More)
The possible role of the endogenous kinins in the control of alcohol intake was assessed in two experiments. In Experiment 1, naive rats, maintained on ad lib food and water, were given daily 40-min access to a 6% (w/v) alcohol solution and water. Daily intraperitoneal (IP) injections of captopril (20 mg/kg) significantly reduced alcohol intake, while(More)
Animals were trained to discriminate amphetamine (1 mg/kg) from saline in a fixed-ratio (FR 10), food-reinforced paradigm. Amphetamine-appropriate responding was engendered by the training dose, and by 3 mg/kg, while at lower doses there was a progressive decrease in the extent of responding on the drug-appropriate lever. The following three novel(More)
The purpose of this study was two-fold: 1) to assess the degree to which para-methoxyamphetamine and para-ethoxyamphetamine maintain self-administration behavior, and 2) to determine the similarity or difference between these drugs and amphetamine in drug discrimination tests. Animals were trained to self-administer 0.3 mg/kg/infusion cocaine on a(More)
