Recovery after stroke is commonly followed by the gait therapy to regain some independence in daily living. Motor weakness, poor motor control and spasticity result in an altered gait pattern and increased energy expenditure during walking. In more than 30% patients some of the gait impairments remain chronic. Ineffective ankle dorsiflexion during swing (foot drop) and failure to achieve heel s...

objectives: the aim of this study was to extract suitable spatiotemporal and kinematic parameters to determine how total knee replacement (tkr) alters patients’ knee kinematics during gait, using a rapid and simplified quantitative two-dimensional gait analysis procedure. methods: two-dimensional kinematic gait pattern of 10 participants were collected before and after the tkr surgery, using a ...

In this paper we study gait transition in a central pattern generator (CPG) model for bipedal locomotion. This model is proposed by Golubitsky, Stewart, Buono and Collins (14; 15) and is studied further by Pinto and Golubitsky (28). It is a network of four coupled identical cells, with D2 symmetry. Each cell is modeled by a system of ordinary differential equations. We briefly review the work d...

Variability raises considerable interest as a promising and sensitive marker of dysfunction in physiology, in particular in neurosciences. Both internally (e.g., pathology) and/or externally (e.g., environment) generated perturbations and the neuro-mechanical responses to them contribute to the fluctuating dynamics of locomotion. Defective internal gait control in Parkinson's disease (PD), resu...

OBJECTIVE To determine how normal gait patterns may change as a result of chronic anterior cruciate ligament deficiency and subsequent reconstructive surgery. DESIGN Gait testing of 10 chronic anterior cruciate ligament deficient subjects prior to and 3 months following reconstructive surgery, and 10 uninjured controls. BACKGROUND There is controversy whether persons with chronic anterior c...

Background It is understood that toe walking involves the absence or limitation of heel strike in the contact phase of the gait cycle. When there is no medical cause of the gait pattern, a diagnosis of idiopathic toe walking (ITW) is made. Although there has been limited research into the pathophysiology of ITW, there has been an increasing number of references proposing that this gait pattern ...

Key points Gait-related arm swing in humans supports efficient lower limb muscle activation, indicating a neural coupling between the upper and limbs during gait. Intermuscular coherence analyses of gait-related electromyography from 20 healthy participants identified significant alpha beta/gamma bands that share common subcortical cortical drivers coordinate rhythmic four-limb gait pattern. Ad...

The development of rehabilitation training program for lower limb injury does not usually include gait pattern design. This paper introduced a gait pattern design by using equations (conditions of walking). Following the requirements of reducing force to the injured side to avoid further injury, we developed a lower limb gait pattern to shorten the stride length so as to reduce walking speed, t...

[Purpose] The aim of this study was to verify how the application of elastic tape to the anterior surface of the thigh changes the knee angle pattern during gait. [Subjects] The subjects were 10 people who showed an abnormal knee angle change pattern during usual walking. They did not show the so-called double knee action. [Methods] Subjects were asked to walk as usual, and then to walk with el...

Background: Deficits in upper body movement have received little attention during gait in cerebral palsy (CP) children with crouch gait pattern (CGP).Objective: Purpose of this research is to describe the correlation of trunk movement with the excessive knee flexion and ankle kinematic in CP children with CGP.Methods: Gait analysis data from 57 limbs of diplegic CP children with CGP and 26 limb...
