Fixator muscles act to reduce or prevent movement at proximal joints to improve force transmission. For example, the muscles of the core (rectus abdominis, obliques, quadratus lumborum, erector spinae) are important fixators; reducing motion of the spine/trunk to enhance force transmission between the extremities and environment. A synonym includes stabilizer muscles.
