One of the major obstacles in developing reliable walking neural prostheses is poor performance of the sensors which are used for gait phases identification. Improper functioning of these sensors causes wrong stimulation pattern selection and wrong stimulation sequencing of the walking neural prostheses. These malfunctions often cause unstable walking patterns in patients that are using the pro...

Physical activity, including running, is important to general health by way of prevention of chronic illnesses and their precursors. To keep runners healthy, it is paramount that one has sound knowledge of the biomechanics of running and assessment of running gait. More so, improving performance in competitive runners is based in sound training and rehabilitation practices that are rooted firml...

Researches are under way based on the concept of passive dynamic walking to improve the efficiency and to realize more natural gait of controlled biped robot. In this research, we investigated the energy based method to find the initial condition for stable one-period gait cycle. The energy balance method, we proposed here, is easier way than the conventional approaches in finding the proper in...

Gait rehabilitation using body weight support on a treadmill is a recommended rehabilitation technique for neurological injuries, such as spinal cord injury. In this paper, a new robotic orthosis is presented for treadmill training. In the presented design the criteria such as low inertia of robot components, backdrivability, high safety and degrees of freedom based on human walking are conside...

The clinical features of the primary progressive freezing gait, a rare and distinct neurological entity, have been described in some articles. This paper describes this gait disorder affecting one patient, whose condition's long course provoked no postural instability. As stated in the literature, the pathophysiology of the primary progressive freezing gait still remains unclear, although the l...

Background Cognitive and visual impairments are common in Parkinson’s disease (PD) and contribute to gait deficit and falls. To date, cognition and vision in gait in PD have been assessed separately. Impact of both functions (which we term ‘visuo-cognition’) on gait however is likely interactive and can be tested using visual sampling (specifically saccadic eye movements) to provide an online b...

Background Limited walking ability is an important problem for patients with multiple sclerosis (MS). A better understanding of how gait impairments lead to limited walking ability may help to develop more targeted interventions. Although gait classifications are available in stroke and cerebral palsy, relevant knowledge in MS is scarce. The purpose of this study is to identify distinctive gait...

At the millimeter scale and in intermediate Reynolds number ( Re) regime, midge mosquito larvae can reach swimming speeds of more than one body length per cycle performing a “figure eight” gait, which their elongated bodies periodically bend nearly into circles then fully unfold. To elucidate propulsion mechanism this motion, we conducted three-dimensional (3D) numerical study, investigates hyd...
