Clinical TrialForce and time recording for validating the sacroiliac distraction test.
The present aim was to investigate whether applied force and time interval of force exposure during the sacroiliac distraction test could discriminate subjects with sacroiliitis pain from healthy subjects. ⋯ There is a need for objective evaluation methods in manual tests that are easy to perform. Recording force and its time interval may be a step towards standardising pain-provocation sacroiliac joint tests.

Comparative StudyBiomechanical responses of the intervertebral joints to static and vibrational loading: a finite element study.
This study was performed to investigate the time-dependent responses of the intervertebral joint to static and vibrational loads. ⋯ The predicted responses implied that vibrational motion may be important in facilitating fluid and metabolic transport of the intervertebral disc.

Clinical TrialGlobal 3D head-trunk kinematics during cervical spine manipulation at different levels.
Determination of the three-dimensional kinematics of the head relative to the upper trunk obtained during a manipulation applied on two different cervical levels and on both sides. ⋯ In spinal manipulative therapy, extreme range of motion as the result of the forces applied is generally believed to represent a major risk for negative side effects, especially with regard to the cervical spine. With a multiple component technique, amplitudes between head and upper trunk were shown not to differ significantly with regard to the side nor to the spinal level. Recorded ranges of motion did not exceed those reported for active motion in literature.
