We studied spatial orientation before and after 21 days of 6° head-down bed rest in 15 subjects. During bed rest, 8 subjects were treated daily with 1 h Gz centrifugation (artificial gravity) (2.5 g at the feet; 1.0 g at the heart), with 7 subjects serving as controls.
Ocular counter-rolling and mbt uk outlet subjective visual mbt boots sale vertical were assessed during 90° whole body roll tilt to the left and right. Ocular counter-rolling was unaffected by bed rest and bed rest + artificial gravity. Performance on the subjective visual vertical task was unchanged mbt flame in the control group, but exhibited a significant increase in error for 48 h after bed rest in the treatment (artificial gravity) group.
Intermittent application of mbt boots uk linear acceleration mbt sandals along the long body axis may have increased the weighting of the… mbt john lewis uk idiotropic vector, resulting in an increased bias of the subjective visual vertical toward the long body axis during 90° roll tilt.
