Evaluation of the effect of load on pattern of motion in Stoop and Squat Lifting
Abstract
Reports of interactive between lumbar spine and hip movement vary for stoop & squat,
loading conditions. This study analysis two groups of subjects (45 subjects) during stoop &
squat lifting with loaded & unloaded. A Three-Dimentional Optoelectric Motion Analysis
System was used to measure the amount of lumbar spine and hip motion during stoop and
squat lifting. Each subject performed stoop and squat lifting with and without weight.
Individuals with loaded tended to move from lumbar spine greater than those with
unloaded, especially in the squat lifting (loaded ROM lumbar spine =23.7 & unloaded ROM
lumbar spine= 15.1). Individuals with loaded tended to move from the lumbar spine joint
smaller than those with unloaded especially in the stoop lifting (loaded ROM lumbar spine
=14 & unloaded ROM lumbar spine= 22.2).
There was a measurable different between two group subject during stoop & squat lifting
with loaded & unloaded. Individuals with loaded tended to move from lumbar spine earlier
than those with unloaded, especially in the squat lifting. Individuals with loaded tended to
move from the hip joint and ankle joint earlier than those with unloaded especially in the
squat lifting. Individuals with loaded tended to move from lumbar spine smaller than those
with unloaded, especially in the stoop lifting.
