INTRODUCTION: Children with spastic cerebral palsy (CP) often develop hamstring contractures, however, the mechanism of contracture formation is not known. Contractures represent a resistance of muscle to increased length. The structural elements responsible for this increased stiffness are also not known [1]. Previous work showed that single fibers from “contractured” muscle tissue has increas...

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...

[Purpose] The effects of various rhythmic auditory stimulation tempos on stroke gait pattern changes when training patients with a smartphone-based rhythmic auditory stimulation application were investigated. [Subjects and Methods] Fifteen patients with chronic stroke were included. Cadence during comfortable walking was measured (baseline). After the baseline findings were recorded, rhythmic a...

Varus knee alignment is a risk factor for medial knee osteoarthritis and is associated with high knee adduction moments. Therefore, reducing the knee adduction moment in varus-aligned individuals with otherwise healthy knees may reduce their risk for developing osteoarthritis. A gait modification that improves dynamic knee alignment may reduce the adduction moment, and systematic training may l...

Human gait is the basic form of human locomotion and the most comfortable and economical way of movement in short distances [1,2]. Despite complex neural control the gait characterises with smooth and repeatable movements in human joints, which can be recorded by cinematographic methods. In the clinical applications gait stereotype is frequently used in human motion analysis to compare the obta...

Previous research indicates that an increased amount of step width variability in humans is associated with an unstable locomotive pattern. For example, the elderly have an increased amount of step width variability compared to their younger counterparts (Ownings & Grabiner, 2004). This notion is further supported by simulations from passive dynamic walking models. Twodimensional passive dynami...
