Precision markedly attenuates repetitive lift capacity.

Unlabelled: This study investigated the effect of precision on time to task failure in a repetitive whole-body manual handling task. Twelve participants were required to repetitively lift a box weighing 65% of their single repetition maximum to shoulder height using either precise or unconstrained box placement. Muscle activity, forces exerted at the ground, 2D body kinematics, box acceleration and psychophysical measures of performance were recorded until task failure was reached.

Changes in socioeconomic inequalities in census measures of health in England and Wales, 1991-2001.

Study Objectives: To investigate changes in socioeconomic inequalities in census measures of health in England and Wales between 1991 and 2001.

Design: Indirect standardisation was used to calculate age standardised rates of limiting long term illness and permanent sickness in men and women in all residential wards in England and Wales in 1991 and 2001. The socioeconomic position of each ward was determined using Townsend deprivation scores.
