Comparative Study
Three-dimensional kinetics of the lumbar spine and hips in low back pain patients during sit-to-stand and stand-to-sit.
Experimental, biomechanical study to determine the kinetics of the lumbar spine and hips during sit-to-stand and stand-to-sit. ⋯ Back pain subjects exhibit compensatory movements and altered load sharing strategies during the sit-to-stand and stand-to-sit activities. Exercise therapy should take account of these changes so that the normal kinematic and kinetic characteristics of the spine and hips can be restored.

We present the positional magnetic resonance imaging findings of a prospective case series of patients undergoing surgery with the Dynesys spinal stabilization device (Zimmer, Inc., Warsaw, IN). ⋯ In vivo, the Dynesys Stabilization System allows movement at the instrumented level, albeit reduced, with no significant increased mobility at the adjacent segments. There was reduction of the anterior disc height without a significant increase of the posterior disc height.

Reanalysis of data derived from longitudinal cohort studies. ⋯ We recommend the 5-item CWOM as a brief clinical measure for whiplash because it is quick to administer and score, and has excellent measurement properties. The CWOM may need to be supplemented with other questionnaires (e.g., when assessment of psychological or emotional health is required).

A prospective, cohort clinical and magnetic resonance imaging (MRI) study of patients with low back pain. ⋯ Early DD in adolescent patients with low back pain predicted the evolution of enhanced DD and herniation in adulthood, but it was not associated with severe low back pain or increased frequency of spinal surgery.

Fear-avoidance beliefs are important determinants for disability in patients with non-specific low-back pain (LBP). The association with self-reported level of physical activity is less known. The aim of the present study was to describe the level of physical activity in patients with chronic non-specific LBP and its relation to fear-avoidance beliefs and pain catastrophizing. ⋯ This study indicates that it seems important for physiotherapists in primary care to measure levels of fear-avoidance beliefs or pain catastrophizing. In particular, the two subscales of the TSK could be of real value for clinicians when making treatment decisions concerning physical exercise therapy for patients with chronic LBP.
