H-reflexes of different sizes exhibit differential sensitivity to low frequency depression.
The amplitude of the H-reflex declines when activated repetitively. The magnitude of decline is greater when the amplitude of the H-reflex is small. To explore whether pre- or postsynaptic factorsExpand

Control of upright stance over inclined surfaces
The present work investigated the control of upright posture on inclined surfaces (14°). Such conditions could, for example, change the contributions of muscle spindles resulting in alterations inExpand

Spinal Mechanisms May Provide a Combination of Intermittent and Continuous Control of Human Posture: Predictions from a Biologically Based Neuromusculoskeletal Model
Several models have been employed to study human postural control during upright quiet stance. Most have adopted an inverted pendulum approximation to the standing human and theoretical models toExpand

Vibratory noise to the fingertip enhances balance improvement associated with light touch
Light touch of a fingertip on an external stable surface greatly improves the postural stability of standing subjects. The hypothesis of the present work was that a vibrating surface could increaseExpand

Presynaptic inhibition compared with homosynaptic depression as an explanation for soleus H-reflex depression in humans
Abstract The H-reflex is depressed for seconds if elicited following a single H-reflex or train of H-reflexes. Presynaptic inhibition from flexor afferents (tibialis anterior) onto soleus IaExpand

Imperceptible electrical noise attenuates isometric plantar flexion force fluctuations with correlated reductions in postural sway
Optimal levels of noise stimulation have been shown to enhance the detection and transmission of neural signals thereby improving the performance of sensory and motor systems. The first series ofExpand

Effectiveness of electrical noise in reducing postural sway: a comparison between imperceptible stimulation applied to the anterior and to the posterior leg muscles
PurposeThe aim of this study was to investigate whether subsensory electrical noise stimulation applied over the tibialis anterior (TA) muscles may reduce postural oscillations during quiet stanceExpand

Postural control during kneeling
Postural control was studied when the subject was kneeling with erect trunk in a quiet posture and compared to that obtained during quiet standing. The analysis was based on the center of pressureExpand

Vibration-induced extra torque during electrically-evoked contractions of the human calf muscles
BackgroundHigh-frequency trains of electrical stimulation applied over the lower limb muscles can generate forces higher than would be expected from a peripheral mechanism (i.e. by direct activationExpand
