Ataxia is presented by various etiologies, including acquired, genetic and degenerative disorders. Although hereditary ataxia suspected when typical symptom of with concurrent identified, it sometimes difficult to diagnose without test. Clinically, next generation sequencing technology has been developed widely used for diagnosis disease. Hereby, we experienced cases genetically confirmed <i...

Gait pattern generation has an important influence on the walking quality of biped robots. In most gait methods, it is usually assumed that torso keeps vertical during walking. It very intuitive and simple. However, may not be efficient. this paper, we propose a with pitch motion (TPM) We also present keeping (TKV) to study effects TPM energy efficiency define cyclic five-link robot several par...

Previous studies have shown major deficits in gait for individuals with peripheral arterial disease before and after the onset of pain. However, these studies did not have subjects ambulate at similar velocities and potential exists that the differences in joint powers may have been due to differences in walking velocity. The purpose of this study was to examine the joint moments and powers of ...

Here, we investigate the role of sensory feedback in gait generation and transition by using a three-dimensional, neuro-musculo-mechanical model of a salamander with realistic physical parameters. Activation of limb and axial muscles were driven by neural output patterns obtained from a central pattern generator (CPG) which is composed of simulated spiking neurons with adaptation. The CPG consi...

Introduction: Historically, assessing the quality of human gait has been a difficult process. Advanced studies can be conducted using modern 3D systems. However, due to their high cost, usage of these 3D systems is still restricted to research environments. 2D systems offer simpler and more affordable solutions. Methods: In this study, the gait of 40 volunteers walking on a treadmill was record...

This paper provides a basis for investigating "The Origin of Artificial Species," as robot can be considered as an artificial creature. To design an artificial creature, a general architecture for the artificial creature is presented and its artificial chromosomes are described. At present the chromosomes are implanted into the software robot living in virtual world, but in the future research ...

Modeling and simulating physical systems have given a lot of conveniences for researchers. The purpose of this work is to introduce a new physical modeling tool in Matlab/Simulink R2012b: 2nd Generation of SimMechanics in Simscape tool, and apply to build as well as to control a Biomechanical system: a powered gait training system designed for hemiplegic patients. Firstly, a brief introduction ...

Background. Approximately 35,000 strokes occur annually in adults below the age of 40, and there is disappointingly little data describing their responses to rehabilitation. The purpose of this analysis was to determine the effects of Poststroke Optimization of Walking using Explosive Resistance (POWER) training in young (<40 years) and older (>60 years) adults and to describe relationships bet...

Biped robot locomotion is one of the active research areas in robotics. In this area, real-time stable walking with proper speed is one of the main challenges that needs to be overcome. Central Pattern Generators (CPG) as one of the biological gait generation models, can produce complex nonlinear oscillation as a pattern for walking. In this paper, we propose a model for a biped robot joint tra...
