Upper cross syndrome, characterized by tight neck and shoulder muscles and weak opposing muscles, can lead to overload in specific areas of the kinematic chain.

“that musculature would tend towards a tightening or an over activation other musc musculature in the upper extremity the serratus which attaches to the ribs and in the back of the the scapula um the deep neck flexors the middle and lower traps would have a tendency to tend towards a weakness and with that tendency towards over utilization or hypertonicity and underutilization inhibition weakness um that would also he also recognized that that would affect the quality of movement throughout the kinematic chain and subsequently would lead to overload in specific areas throughout that kinematic chain”

“for example with an upper cross syndrome meaning the neck and shoulder region with demands of of life and the tendency towards postural habituation such as with sustained seated postures there's a tendency towards uh the muscles in the back of the neck the occipital muscles the sternocleidomastoid muscle which is the muscle that and also attaches to the skull and down to the sternoclavicular joint the pec muscles the upper traps that musculature would tend towards a tightening or an overactivation other musc musculature in the upper extremity the serratus which attaches to the ribs and in the back of the scapula the deep neck flexors the middle and lower traps would have a tendency to tend towards a weakness and with that tendency towards over utilization or hypertonicity and underutilization inhibition weakness that would also he also recognized that that would affect the quality of movement throughout the kinematic chain and subsequently would lead to overload in specific areas throughout that kinematic chain”
