ReviewThe relationship between psychosocial work characteristics and low back pain: underlying methodological issues.
To evaluate the current epidemiological evidence linking psychosocial work characteristics with low back pain. ⋯ This review attempts to identify and address methodological issues in the literature evaluating the relationship between psychosocial work characteristics and lower back pain. Implications for future research are presented.

Comparative StudyThe effect of load on the coordination of the trunk for subjects with and without chronic low back pain during flexion-extension and lateral bending tasks.
To evaluate if patients move their trunk sections differently than normal subjects and to determine if these differences increase when lifting a load. ⋯ The lumbar-pelvic rhythm is routinely used to evaluate low back impairments. The use of kinematic measures enhance the objectivity of the examination but the large variability of the results impair the discrimination power. Lifting a load during such an evaluation might magnify the low back impairments and increase the discrimination power of this measure.

The effects of the lower extremity joint motions on the total body motion in sit-to-stand movement.
The purpose of this study is to investigate the effects of lower extremity joint angular motions on the whole body linear motions in a sit-to-stand movement using a biomechanical model that describes the whole body linear velocity vector as functions of lower extremity joint angular velocities. ⋯ The model and the results of this study can be applied to study the control strategies, falls, and assessments of functional impairments in the sit-to-stand movement.
