Abnormal posturing is an involuntary flexion or extension of the arms and legs, indicating severe brain injury. It occurs when one set of muscles becomes incapacitated while the opposing set is not, and an external stimulus such as pain causes the working set of muscles to contract. [ 1 ]
Rounded shoulder posture (RSP), also known as “mom posture”, [1] is a common postural problem in which the resting position of the shoulders leans forward from the body’s ideal alignment. [1] Patients usually feel slouched and hunched, [ 2 ] with the situation deteriorating if left untreated.
Hips – Common problems in the hips are tight hip flexors, [4] which causes poor lifting posture, hip flexion contracture, which means the lack of postural awareness, and thoracic hyperkyphosis, which causes the individual to compensate for limited hip turn out (which is essential to dances such as ballet).
The cantilevered (poked forward) head position loads the spine up to several times more than erect posture, because of the increased moment arm. [31] So the posterior neck muscles (especially the upper fibres of trapezius) holding the head in its forward position, often sustained for many hours, can strain, producing individual myofibril and ...
anterocollis: forward flexion of the head and neck [6] and brings the chin towards the chest [5] retrocollis: hyperextension of head and neck backward [7] bringing the back of the head towards the back [5] A combination of these movements may often be observed. Torticollis can be a disorder in itself as well as a symptom in other conditions.
A diagram illustrating crossed extensor reflex. The crossed extensor reflex or crossed extensor response or crossed extension reflex is a reflex in which the contralateral limb compensates for loss of support when the ipsilateral limb withdraws from painful stimulus in a withdrawal reflex. [1]
Like the reflex, a positive fencing response resembles the en garde position that initiates a fencing bout, with the extension of one arm and the flexion of the other. Tonic posturing preceding convulsion has been observed in sports injuries at the moment of impact [2] [3] where extension and flexion of opposite arms occur despite body position ...
Iliocostal friction syndrome most commonly occurs bilaterally as a result of spinal osteoporosis. [2] Osteoporosis is a condition in which the bone density and quality deteriorates, resulting in an increased risk for fractures. More than 2 million fractures occur annually in the United States due to osteoporosis. [9]
