As shown in figure 6A, B, in patient A, who presents with a light left cupula, head rotation to the left (affected side) from the neutral head position caused a greater SPV than head rotation to the right (healthy side) (8.9sin(x+149) vs 4.1sin(x+14.1sin
When the left side is affected, a head rotation to the left away from the perceived neutral head position (inserted 'c' in figure 6A, B) results in a deviation of light cupulae in the ampullopetal direction (inserted 'd' in figure 6A) and heavy cupulae in the ampullofugal direction (inserted 'd' in figure 6B).
In patient B, who presented with a heavy left cupula, head rotation to the left (affected side) from the neutral head position caused a lesser SPV than head rotation to the right (healthy side) (3.6sin(x−22.0) vs 7.0sin(x−22.0)).
Methods: We examined 14 healthy subjects, wearing goggles equipped with an infrared CCD camera, and sitting on a chair which was designed to stimulate a pair of the VSCCs by tilting the head 60° backward with a 45° rotation to the left or right side from the sagital plane.
An optokinetic stimulus induced by the rotation of a disc from the left side to the right side causes an inclination of the body to the right side to compensate for the body motion illusion to the left.
This study was designed to compare the rotation of the left ventricular (LV) apex and base, LV synchrony between LV apical and basal rotation, and LV twist, changing from intrinsic atrioventricular conduction to right ventricular apical (RVA) pacing.
Step 3: Continue with a rotation to the left and return to center to complete one rep.
Rotation of the patient to the right artificially increases the VPW, while rotation to the left decreases the measurement [ 11].
During rotation to the left, only the right facet joints bore contact force.
Articular damage patterns were asymmetrically rotated on both inserts, consistent with femoral internal rotation (tibial external rotation) of the right TKA and femoral external rotation (tibial internal rotation) of the left TKA.
