摘要

One of the most interesting topics in occupational research for musculoskeletal disorders is an investigation into why individuals respond differently to pushing forces taking into account their strength. The study reports the results of the strength of 12 subjects during one-handed pushing and the geometries of their shoulder joints derived from magnetic resonance imaging (MRI) scans. The measurements of mean force during pushing were recorded when the upper right arm was abducted in the frontal plane from 5 to 30 degrees during maximum voluntary contraction (MVC). The three characteristic shoulder types A, B and C were identified in the group: type A - glenoid with a radius that is larger than that of the humerus, type B, glenoid and humerus with the same radius, and type C, glenoid with a radius that is smaller than that of the humerus. The congruency of the shoulder joint is not a straightforward related factor on the maximum acceptable load during pushing. There may exist other geometric relationships between the anatomic variables which have influence on the maximum load during pushing.
