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 ]
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]
The most important risk factors for osteoporosis are advanced age (in both men and women) and female sex; estrogen deficiency following menopause or surgical removal of the ovaries is correlated with a rapid reduction in bone mineral density, while in men, a decrease in testosterone levels has a comparable (but less pronounced) effect. [33] [34]
These paravertebral muscles have a great influence over the walking stance and gait of a patient, so fatty infiltration and degradation of these muscle lead to the characteristics that easily define BSS, such as the anterior flexion of the back combined with an ability to keep upright with any kind of support (e.g., holding onto a table).
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 or gravity. The fencing response emerges from the separation of tonic posturing from convulsion and refines the tonic posturing phase as an immediate forearm motor ...
Achondroplasia (a disorder where bones grow abnormally, which can result in short stature as in dwarfism), spondylolisthesis (a condition in which vertebrae slip forward), and osteoporosis (the most common bone disease in which bone density is lost resulting in bone weakness and increased likelihood of fracture) are some of the most common ...
Senile osteoporosis has been recently recognized as a geriatric syndrome with a particular pathophysiology. There are different classification of osteoporosis: primary, in which bone loss is a result of aging and secondary, in which bone loss occurs from various clinical and lifestyle factors. [1]
Posturography is the technique used to quantify postural control in upright stance in either static or dynamic conditions. Among them, Computerized dynamic posturography (CDP), also called test of balance (TOB), is a non-invasive specialized clinical assessment technique used to quantify the central nervous system adaptive mechanisms (sensory, motor and central) involved in the control of ...
