Recent models of biological motion processing focus on the articulational aspect of human walking investigated by point-light figures walking in place. However, in real human walking, the change in the position of the limbs relative to each other (referred to as articulation) results in a change of body location in space over time (referred to as translation). In order to examine the role of th...

Quantitative assessment of movement using motion capture provides insights on mobility which are not evident from clinical evaluation. Here, in older individuals that were healthy or had suffered a stroke, we aimed to investigate their balance terms changes body kinematics and muscle activity. Our research question involved determining the effects post- compared pre-sensorimotor training exerci...

Background: A lot of the ambulating children with spastic diplegia were able to walk with flexed hips, knees and ankles this gait pattern is known as crouch gait. The most needed functional achievement of diplegic children habilitation is to be able to walk appropriately. The development of an independent and efficient walking is one of the main objectives for children with cerebral palsy espec...

OBJECTIVE To investigate whether simple clinical measures can predict walking ability after lower limb prosthetic rehabilitation. DESIGN Prospective observational study. SUBJECTS Ninety five adults who were assessed as suitable for lower limb prosthetic rehabilitation by the multidisciplinary team. METHODS Information regarding baseline clinical factors (amputation details, comorbidities,...

A major question in neuroethology is how animals coordinate transitions between incompatible behavior patterns. The recent demonstration that the lateral giant (LG) tailflip is inhibited during eating (Krasne and Lee, 1988) suggested to us that inhibition may play a general role in preventing maladaptive transitions between incompatible behavior patterns. We wished to determine whether the LG t...

In many animals, the effects of sensory feedback on motor output change during locomotion. These changes can occur as reflex reversals in which sense organs that activate muscles to counter perturbations in posture control instead reinforce movements in walking. The mechanisms underlying these changes are only partially understood. As such, it is unclear whether reflex reversals are modulated w...

In this paper, we propose a control system that changes the compliance based on the walking speed to stabilize biped walking on rough terrain. The proposed system does not use the inclination of the terrain. Instead, the system changes walking modes depends on its walking speed. In the downhill terrain, when the walking speed is increased, the stiffness of the ankle in the support phase is cont...

F the past decade, we have assessed the posture, hindlimb dynamics, and motor patterns for different forms of cat locomotion, including forward and backward walking 4 and slope walking. Two of our goals for undertaking these studies have been to identify the roles of muscle and inertial forces in the control of limb motion (reviewed in ref. 7) and to determine the mutability of motor patterns a...
