Achilles tendon vibration shifts the center of pressure backward in standing and forward in sitting in young subjects

Perception of body movement when real and simulated displacements are combined

The simulated whole-body displacement evoked by Achilles tendon vibration was able to either enhance or disrupt the perception of real, slow, whole- body tilt movements, depending on the congruence between the direction of real and simulated displacements.

Sensory Integration during Vibration of Postural Muscle Tendons When Pointing to a Memorized Target

Vibrating ankle muscles in freely standing persons elicits a spatially oriented postural response. For instance, vibrating the Achilles tendons induces a backward displacement of the body while

Effects of tibialis anterior muscle vibration on quiet stance

Postural responses obtained during the quiet stance conditions suggest that the distorted input associated with vibration was not fully down weighted by the sensory motor system during quiet upright stance, despite repeated exposure to vibration throughout the testing protocol.

Postural challenge and adaptation to vibration-induced disturbances

It is concluded that although the absence of any postural challenge concomitant to the sensory stimulation prevented adaptation to occur, a minimal challenge was sufficient.

Effects of tendon vibration during one-legged and two-legged stance in elderly individuals

The decrease in COP sway may improve the ability to balance during one-legged stance by combined vibration in elderly subjects, and is important for the use of somatosensory information processing to regulate postural adjustments in the elderly.

Tendon vibration during submaximal isometric strength and postural tasks

The vibration-induced muscle excitation and accompanying increase in motor output, probably due to excitatory Ia afferent input, was confirmed during strength and postural tasks, however, motor output attenuates when the magnitude of central drive to the ankle muscles increases.

Vibration stimulation effect on biomechanical variation of lower-limb joint according to vibration perception threshold

The biomechanical variation in the lower-limb joints according to the characteristics of the mechanical vibration stimulation flowing into Achilles tendon and tibialis anterior tendon during gait, in consideration of the vibration perception threshold and vibration frequency is analyzed.



Foot sole and ankle muscle inputs contribute jointly to human erect posture regulation

It is proposed that tactile and proprioceptive information from the foot soles and flexor ankle muscles might be co‐processed following a vector addition mode to subserve the maintenance of erect stance in a complementary way.

Postural responses to vibration of neck muscles in patients with idiopathic torticollis.

The results suggest that neck proprioceptive input retains local postural functions in ST, however, it is relatively ignored in the context of the whole body postural control and spatial orientation.

Effects of neck muscles vibration on the perception of the head and trunk midline position

Results suggested that the input from neck muscle proprioceptors participates directly to the elaboration of the Egocentric space and the question may be raised as to how the sensory cues interacted in their contribution to the neural generation of an egocentric, body centred coordinate system.

Kinaesthetic role of muscle afferents in man, studied by tendon vibration and microneurography

The characteristics of the vibration-induced illusory movements and the muscle spindle responses to tendon vibration and to active and passive joint movements strengthened the possibility of the contribution of primary endings to kinaesthesia, as suggested by several previous works.

Body orientation and regulation of the center of gravity during movement under water.

The results suggest that "axial synergies" associated with upper trunk movements are learned motor habits that regulate the center of gravity position regardless of the equilibrium constraints.

Effect of slow, small movement on the vibration-evoked kinesthetic illusion

Whether the exaggerated perception of slow, small movement during vibration is better explained by contributions of non muscle spindle Ia afferents or by changes in the mechanical transmission of vibration to the receptor is discussed.

Perceptual and motor effects of agonist-antagonist muscle vibration in man

The studies show that the velocity and the amplitude of the ilusory movement is related to the difference in vibration frequency applied to the two muscles, and support the notion that the sensation of movement at a joint may be derived from a central processing of the proprioceptive inflow data obtained from flexor and extensor muscles.

Contribution of Somesthetic Information to the Perception of Body Orientation in the Pitch Dimension

Data suggested that gravity-based somesthetic cues are more informative than otolithic cues for the perception of a quasi-static body orientation, when pitching at very slow velocities.

Effects of Upper Limb Muscle Vibration on Human Voluntary Wrist Flexion-Extension Movements

The effect of upper limb muscle tendon vibration during alternating step flexion-extension movements about the wrist was studied and indicated the pattern of transjoint projections from elbowextensor and flexor muscles to motoneurons supplying wrist extensor and Flexor muscles play an important role in coordinated movement of wrist and elbow joints.
