The possibility that infantile nystagmus (IN) may reflect a failure in early sensorimotor integration has been proposed for more than a century, but is only recently being borne out in animal studies. The underlying neural and genetic substrate for this plasticity is complex. We propose that, in most cases, IN develops as a developmental response to reduced contrast sensitivity to high-spatial ...

INTRODUCTION To compare the perioperative outcomes and complications of monopolar and bipolar transurethral resection of bladder tumors (TURBT) in patients with coronary artery disease (CAD). MATERIALS AND METHODS A total of 90 CAD patients with newly diagnosed bladder cancer who underwent TURBT were randomized into monopolar TURBT (M-TURBT) and bipolar TURBT (B-TURBT) groups. Primary outcome...

PURPOSE To report on the development of infantile nystagmus in a patient's first year of life. METHODS A case study using consecutive photo-oculographic and electro-oculographic eye movement recordings in the subject ranging between 1 and 12 months of age. RESULTS Although no nystagmus was present at 5 weeks of age, square-wave jerks were recorded at 7 weeks, and a small pendular nystagmus ...

The investigation of patellar tendon reflex involves development of a reflex hammer holder, kinematic data collection and analysis of patellar reflex responses using motion analysis techniques. The main aim of this research is to explore alternative means of assessing reflexes as a part of routine clinical diagnosis. The motion analysis system was applied to provide quantitative data which is a...

An online method for obtaining smooth, jerk-bounded trajectories has been developed and implemented. Jerk limitation is important in industrial robot applications, since it results in improved path tracking and reduced wear on the robot. The method described herein uses a concatenation of fifth-order polynomials to provide a smooth trajectory between two way points. The trajectory approximates ...

The vestibular responses evoked by transmastoid galvanic stimulation (GS) in the rectified soleus electromyogram (EMG) in freely standing human subjects disappear when seated. However, a GS-induced facilitation of the soleus monosynaptic (H and tendon jerk) reflex has been described in few experiments in subjects lying prone or seated. This study addresses the issue of whether this reflex facil...

In this study the alpha band waves of low to moderately skilled pistol shooters are evaluated to examine the performance of the individuals under a competitive environment. The factors that cater to success in the autonomous stage of learning are different for the athlete. There has been investigation of the brain patterns of experts, while performing a task is efficient and in accord with Fitt...

Various rehabilitation robots have been employed to recover the motor function of stroke patients. To improve the effect of rehabilitation, robots should promote patient participation and provide compliant assistance. This paper proposes an adaptive admittance control scheme (AACS) consisting of an admittance filter, inner position controller, and electromyography (EMG)-driven musculoskeletal m...

In this paper, we propose a novel trajectory generation method for autonomous excavator teach-and-plan applications. Rather than controlling the to precisely follow teaching path, proposed transforms arbitrary slow and jerky of human excavation into topologically equivalent path that is guaranteed be fast, smooth dynamically feasible. This optimizes trajectories in both time jerk aspects. A spl...

This paper presents planning of smooth trajectories using the asymmetric profiles displacement, velocity, acceleration and jerk described higher degree polynomials. The presented way determination polynomial asymmetry coefficients as well motion time includes procedure at both constraints single kinematic quantities, i.e., acceleration, introducing a few simultaneously. Moreover, method with in...
