Background: More than half of the patients harbouring the m.3243A > G mutation were found to have trouble maintaining balance when walking in a recent study by our group. Others demonstrated that these patients had an abnormal gait pattern, as quantified by gait analysis. Gait analysis is an emerging method to quantify subtle changes in walking pattern, also during therapeutic interventions. Th...

Approximating the complexity of natural locomotor conditions provides insight into the diversity of mechanisms that enable animals to successfully navigate through their environment. When exposed to vortices shed from a cylinder, fishes hold station by adopting a mode of locomotion called the Kármán gait, whereby the body of the fish displays large, lateral oscillations and the tail-beat freque...

While gait retraining paradigms that alter knee loads typically focus on modifying kinematics, the underlying muscle force modifications responsible for these kinematic changes remain largely unknown. As humans are generally thought to select uniform gait muscle patterns such as strategies based on fatigue cost functions or energy minimization, we hypothesized that a kinematic gait change known...

conclusions zebris movement analysis system is a highly reliable instrument for the measurement of gait parameters at different speeds in healthy athletes and those after acl reconstruction surgery. this implies its use in the assessment and treatment process of gait deficits in such a clinically important population. background reconstruction surgery is one of the treatment methods after an an...

Gait disorder is very common in neurodegenerative diseases and differentiating among the same kinematic design a challenging task. The muscle activity responsible for creation of patterns. Hence, one optimal way to monitor this issue analyse pattern identify gait disorders. In paper, we will investigate possibility identifying GAIT disorders using EMG patterns with help various machine learning...

The function of the human hip joint during the stance phase of walking can be characterized with a configuration of simple mechanical elements. This combination of elements is capable of providing general hip behavior in the sagittal plane. Data was collected from two healthy, young subjects who walked at slow, normal and fast gait speeds. The hip can be modeled with a torque actuator and two i...

In 1983–1984, a 29-year-old battery factory worker gradually developed gait difficulties and tremor. In 1984, he was found to have severely elevated serum manganese levels and retired from work. Clinical examination in 1984 (videos 1–3 on the Neurology Web site at www.neurology.org) showed bilateral foot dystonia and profound parkinsonism. His gait was shuffling, although he lifted his knees re...

The present study investigated the effects of wearing a non-woven face mask and performing calculation task, while walking, on gait pattern, breathlessness, performance. Twenty-one healthy adult males walked 4.0 km/h 6.0 treadmill with without mask. A task using smartphone was added to participants were asked perform two-digit addition tasks displayed screen as quickly accurately possible. Hear...

This systematic review of the literature evaluates the validity of existing classifications of gait deviations in children with cerebral palsy (CP). Numerous efforts have been made to develop classification systems for gait in CP to assist in diagnosis, clinical decision-making and communication. The internal and external validity of gait classifications in 18 studies were examined, including t...

The gait transition during locomotion in legged animals is an attractive phenomenon from the point of view of both robotics and biology. In this paper we will show by means of a mathematical model that the optimal gait pattern is selected according to energetic e ciency, including the energy loss due to the heat emissions of actuators.
