Biomechanical and psychophysical evaluation of using a two-wheel cart to transport loads over a curb
(150 lb), the forces exerted on the force plates (p=0.0001)
(p=0.0014)moments at the knee increased. For the longer
(p=0.0027), and the dynamic (p=0.0143) and static
a curb is a dynamic activity. Recommendations include use of
a wheel larger than 20.3 cm (8 in) and redesign of the runner
accelerations at the hip (p=0.0442) and L5/S1 (p=0.0145) as
accelerations at the shoulder (p=0.0356) and elbow (p=0.0090)
also increased for the heavier load. For the smaller
and knee (p=0.0260) increased for the heavier load. The
and the dynamic moments (P=0.0001) at the shoulder, hip,

at L5/S1 increased. The psychophysical study (n=20)

biomechanical study (n=4) involved altering the amount of

of the average load of 203.0 kg (447.5 lb) to tilt the cart
of the load the worker was willing to transport with the cart
on the cart. Also, stack loads up until it is necessary to

The purpose of this study was to evaluate the use of a
