Musculoskeletal model of awkward carrying postures
Improper posture of carrying loads can cause low back disorders. This study investigates the impact of using a footstool in spinal force and muscle activity when: (1) pushing/pulling load farther/nearer from the body and (2) twisting the trunk while carrying load. A whole body musculoskeletal mod...

| description | Improper posture of carrying loads can cause low back disorders. This
study investigates the impact of using a footstool in spinal force and muscle activity
when: (1) pushing/pulling load farther/nearer from the body and (2) twisting
the trunk while carrying load. A whole body musculoskeletal model carrying a light
load of 5, 7.5 and 10 kg is developed and inverse dynamics analyzes are conducted.
Electromyography activities are also recorded to compare to the results from analyzes.
Analyzes demonstrated that using a footstool when carrying a light load can
reduce the intradiscal compression force. The results from the analysis are found to
be consistent with the electromyogram measurement. This study suggests that load
should be positioned closer to the body and footstool of 5 cm height should be used
to reduce spinal forces and muscle activity on the lumbar region. |
