AbstractReports 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.en
