If one of these groups becomes weakened fromany cause such as paralysis, strain, or lack of use, it no longerpulls evenly against its antagonistic group; these unopposedmuscles then overpull and cause more or less change of formin the body, which may become sufficiently great to cause a realdeformity. In the properly poised body all muscles have a slight grpup of antagonists is working slightly, holding the partthey move poised between them, so that movements can be quicklyand easily made.
