“…Hence, the relationship between muscle activity and body movement is complex, and cannot simply be through a parallel change of EMG activity and movement variance. The control of postural stability is regulated by postural muscles that form an uninterrupted muscular chain that extends from the head to the feet (Roll et al, 1989) as confirmed by the induced balance perturbations caused by proprioceptive vibration at various locations (Courtine et al, 2007). Thus, one possibility is that during some periods of time some other postural muscles along the muscular chain may influence the body movements more than the gastrocnemius and tibialis anterior muscles.…”

“…A number of studies have demonstrated that tendon vibration, which almost selectively activates muscle spindle primary endings and elicits a discharge in the fastconducting large-diameter group Ia afferent fibers (Roll et al 1989a), can induce oriented postural imbalance (Eklund 1969;Kavounoudias et al 1999;Lund 1980;Roll et al 1989b) as well as direction-specific gait deviations (Bove et al 2001(Bove et al , 2002Courtine et al 2001Ivanenko et al 2000a,b;Verschueren et al 2002Verschueren et al , 2003.…”

We performed a whole-body mapping study of the effect of unilateral muscle vibration, eliciting spindle Ia firing, on the control of standing and walking in humans. During quiet stance, vibration applied to various muscles of the trunk-neck system and of the lower limb elicited a significant tilt in whole body postural orientation. The direction of vibration-induced postural tilt was consistent with a response compensatory for the illusory lengthening of the stimulated muscles. During walking, trunk-neck muscle vibration induced ample deviations of the locomotor trajectory toward the side opposite to the stimulation site. In contrast, no significant modifications of the locomotor trajectory could be detected when vibrating various muscles of the lower as well as upper limb. The absence of correlation between the effects of muscle vibration during walking and standing dismisses the possibility that vibration-induced postural changes can account for the observed deviations of the locomotor trajectory during walking. We conclude that the dissimilar effects of trunk-neck and lower limb muscle vibration during walking and standing reflect a general sensory-motor plan, whereby muscle Ia input is processed according to both the performed task and the body segment from which the sensory inflow arises.

“…The small but fast vibration cycles almost selectively induce a train of action potentials in the primary endings connected to the large-diameter group Ia afferent fibers. The discharge follows one-to-one the vibration cycles within a wide range and lasts as long as vibration continues (Burke et al 1976;Roll et al 1989a). Both human primary and secondary spindle endings respond to vibration stimuli (Burke et al 1976).…”

“…Subjects can perceive an illusion of limb movement in the direction that would lengthen the vibrated muscles: the spindle discharge is interpreted as muscle lengthening and limb displacement (Craske 1977;Goodwin et al 1972;Roll and Vedel 1982). Interestingly, motor rather than somatosensory areas seem to convey the illusion of limb movement (Naito et al 1999).…”

“…In "neglect" patients, neck muscle vibration can compensate the horizontal displacement of the sagittal midplane (Karnath 1994;Karnath et al 1993). In standing subjects, neck muscle vibration induces body tilt and increased sway, suggesting that posture is organized with respect to a "body schema," to the construction of which neck input contributes together with eye and skeletal muscle (Eklund 1972;Gurfinkel et al 1995;Ivanenko et al 1999;Kavounoudias et al 1999;Roll et al 1989b;Smetanin et al 1993). Most likely, the parietal cortex contributes to the egocentric representation of space, since many of its areas receive signals from neck muscles and from the labyrinth (Bottini et al 2001).…”

Unilateral long-lasting vibration was applied to the sternomastoid muscle to assess the influence of asymmetric neck proprioceptive input on body orientation during stepping-in-place. Blindfolded subjects performed 3 sequences of 3 trials, each lasting 60 s: control, vibration applied during stepping (VDS), and vibration applied before stepping (VBS). VDS caused clear-cut whole body rotation toward the side opposite to vibration. The body rotated around a vertical axis placed at about arm's length from the body. The rotation did not begin immediately on switching on the vibrator. The delay varied from subject to subject from a few seconds to about 10 s. Once initiated, the angular velocity of rotation was remarkably constant (about 1°/s). In VBS, at the beginning of stepping, subjects rotated for a while as if their neck were still vibrated. At a variable delay, the direction of rotation reversed, and the effects were opposite to those observed during VDS. Under no condition did head rotation, head roll, or lateral body tilt accompany rotation. The results confirm and extend the notion that the neck proprioceptive input plays a major role in body orientation during locomotion. The body rotation does not seem to depend on the same mechanisms that modify the erect posture; rather, the asymmetric neck input would seem to modify the egocentric body-centered coordinate system.
