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 ]
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 ...
Locomotor effects of shoes are the way in which the physical characteristics or components of shoes influence the locomotion neuromechanics of a person. Depending on the characteristics of the shoes, the effects are various, ranging from alteration in balance and posture, muscle activity of different muscles as measured by electromyography ...
It is identified by an abnormal thoracolumbar spinal flexion, which is a forward bending of the lower joints of the spine, occurring in a standing position. In order to be classified as BSS, the anterior flexion (the lower back bending) must be of 45 degrees anteriorly. This classification differentiates it from a similar syndrome known as ...
In skeletal muscles, this helps maintain a normal posture. Resting muscle tone varies along a bell-shaped curve. Low tone is perceived as "lax, flabby, floppy, mushy, dead weight" and high tone is perceived as "tight, light, strong". Muscles with high tone are not necessarily strong and muscles with low tone are not necessarily weak.
Experts say bad posture can lead to a lot of health problems.
Brain death - Lazarus sign. The Lazarus sign or Lazarus reflex is a reflex movement in brain-dead or brainstem failure patients, [1] which causes them to briefly raise their arms and drop them crossed on their chests (in a position similar to some Egyptian mummies).
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.
