Patients underwent clinical examination and had instrumented gait analysis before evaluating their equinus under anaesthesia and muscle relaxation at the time of surgery to improve gait. The performance of the clinical examination, the subjective interpretation of gait analysis results, and the application of the neural network…

[A case of chronic bromvalerylurea intoxication due to habitual use of commercially available nonsteroidal anti-inflammatory drugs presenting an indefinite hyperchloremia].

A 75-year-old man was admitted to our hospital with disorientation and progression of speech disturbance and gait disturbance. He had been given a diagnosis of cervical spondylosis about four years previously, and gait disturbance and numbness in his extremities have been gradually increasing. Hyperchloremia and a careful history taking, which led to the discovery of habitual use of an analgesic containing bromvalerylurea, suggested bromism. A high level of bromide in serum yielded a diagnosis of bromism. Disorientation and speech disturbance were treated and improved by infusion diuresis. Gai…

L-dopa-induced air-stepping in preweanling rats. I. Effects of dose and age.

The effects of several doses of L-DOPA (25, 50, 75 and 100 mg/kg) on air-stepping were studied in rats on the day of birth and on 5, 10, 15 and 20 days of age. Occurrence of air-stepping increased and latency to air-stepping generally decreased with dose except at 10 days of age; duration of air-stepping increased with increasing dose of L-DOPA at every age. The occurrence of a variety of air-stepping gaits was age-dependent. On the day of birth, air-stepping consisted primarily of episodes of forelimb alternation; on days 5-20, diagonal progression was the predominant gait, but beginning at d…

Interaction between active and passive knee stabilizers during level walking.

The gait of normal subjects and patients with varus deformities at the knee was studied by analyzing the interaction between the dynamic (muscular) and passive (ligamentous) restraints affecting lateral stability of the knee. A statistically determinant model predicted that the midstance-phase adducting moment during normal gait would cause lateral knee joint opening if either antagonistic muscle force and/or pretension in the lateral soft tissues were not present at the knee. The patient group tended to compensate for a high midstance-phase adducting moment by walking with a style of gait tha…
