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 ]
Trendelenburg gait, named after Friedrich Trendelenburg, is an abnormal human gait.It is caused by weakness or ineffective action of the gluteus medius muscle and the gluteus minimus muscle.
People with dystonia experience tightness, cramping, fatigue, involuntary sustained or repetitive muscle contractions that can be painless or painful and resulting in abnormal posturing, twisting motions, and even tremors. [1] [2] Focal dystonia typically presents in adults, more commonly in women ranging from ages 30 through 40. [1]
Analogous to Romberg's sign, the abnormal posturing is most pronounced when the eyes are closed as visual inputs are unavailable to guide corrective movements. Paradoxically, eye closure may decrease the amount of movement as the visual cues probably trigger corrective movements which return the limb to the desired "baseline" allowing a new ...
The progression of SPS depends on whether it is a typical or abnormal form of the condition, and the presence of comorbidities. [34] Early recognition and neurological treatment can limit its progression. SPS is generally responsive to treatment, [35] but the condition usually progresses and stabilizes periodically. [36]
Dystonia is a neurological hyperkinetic movement disorder in which sustained or repetitive muscle contractions occur involuntarily, resulting in twisting and repetitive movements or abnormal fixed postures. [3] The movements may resemble a tremor. Dystonia is often intensified or exacerbated by physical activity, and symptoms may progress into ...
Dystonia is a neurological movement disorder characterized by sustained muscle contraction leading to abnormal posture, twisting, and repetitive movement. In Pisa Syndrome specifically there is commonly a tonic flexion of the trunk of the body to one side, leading to a slight lean (reminiscent of the Leaning Tower of Pisa , hence the name "Pisa ...
Gait abnormality is a deviation from normal walking ().Watching a patient walk is an important part of the neurological examination. Normal gait requires that many systems, including strength, sensation and coordination, function in an integrated fashion.
