introduction: sensory-motor control and in general gaining balance will be impaired after an ankle injury and in fatigue situations. the aim of this research was to study the effect of exercise-based fatigue on static and dynamic balance in mountaineering athletes who were successful in returning to a suitable level of physical activity after an ankle sprain injury. materials and methods: 25 ac...

Quantitative analysis of gait was performed in 20 parkinsonians before and 1 h after the acute administration of L-Dopa in order to discriminate between the Dopa-sensitive and the Dopa-resistant kinematic gait parameters. The stride length and the kinematic parameters (swing velocity, peak velocity) related to the energy were Dopa-sensitive. The improvement of the bent forward posture by L-Dopa...

Steady state human locomotion at level ground needs compensatory energy input against impulsive energy loss during heel strike. Ground push-off by the stance leg right before the onset of double support phase appeared to be four times energy efficient than the an active hip torque generation during the swing phase [1]. However, if there is biomechanical constraint applied to the maximum allowab...

The purpose of this study was to see whether an electromyographic (EMG) index of gait instability is applicable to the developmental process of supported walking in normal neonates and infants. In six neonates ranging in age from 14 to 26 days after birth, EMGs of stepping were recorded at approximately from one to four week intervals until around four months. Additionally, longitudinalEMGs of ...

During free behaviors animals often experience lateral forces, such as collisions with obstacles or interactions with other animals. We studied postural reactions to lateral pulses of force (pushes) in the cat during standing and walking. During standing, a push applied to the hip region caused a lateral deviation of the caudal trunk, followed by a return to the initial position. The corrective...

We present clinical features and tremor characterization in a patient with Parkinson's disease (PD) as well as in two cases of essential tremor (ET) with some parkinsonian features but no evidence of dopaminergic terminal loss on (123)I-FP-CIT Single Photon Emission Computed Tomography (SPECT). Relatively slow frequency rest tremor and bilateral upper extremity bradykinesia without decrementing...

This study was conducted to investigate the effects of asymmetrical body posture alone, i.e., the effects seen in children with mild scoliosis, vs. the effects of body posture control impairment, i.e., those seen in children with unilateral cerebral palsy on gait patterns. Three-dimensional instrumented gait analysis (3DGA) was conducted in 45 children with hemiplegia and 51 children with mild ...

Maintaining balance and postural stability while performing functional activities is critical to an individual's independence and quality of life. When individuals are unable to maintain their total-body center of mass (COM) within the base of support, a loss of balance may result, leading to a fall. Effective interaction between the environment and the neuromuscular and musculoskeletal systems...

objectives: postural control deficit is one of the most important problems in children with spastic cerebral palsy (cp). the purpose of this paper is to review the reactive postural control in spastic children with cp. methods: researches on development of reactive postural control in typically developing (td) children and children with cerebral palsy (cp) were analyzed. results: the results of...

The term motion sickness was originally introduced to provide a nosological classification for disorders elicited by exposure to unusual patterns of motion, such as sea sickness, train sickness, and swing sickness. The term came to subsume air sickness as well, and in recent years, simulator sickness, space sickness, and cybersickness (virtual environment sickness). It is now recognized that bo...
