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]
A flail limb (also flail arm or flail leg) is a medical term which refers to an extremity in which the primary nerve has been severed or ceased to function, resulting in complete lack of mobility and sensation. Although blood typically continues to flow through the limb, it is completely useless and potential for surgical repair is limited.
Flaccid paralysis is a neurological condition characterized by weakness or paralysis and reduced muscle tone without other obvious cause (e.g., trauma). [1] This abnormal condition may be caused by disease or by trauma affecting the nerves associated with the involved muscles.
Replantation or reattachment is defined as the surgical reattachment of a body part (such as a finger, hand. arm, toe, foot, or leg) that has been completely cut from the body. [1] Examples include reattachment of a partially or fully amputated finger, or reattachment of a kidney that had had an avulsion-type injury .
The opposite of varus is called valgus. The terms varus and valgus always refer to the direction that the distal segment of the joint points. For example, in a valgus deformity of the knee, the distal part of the leg below the knee is deviated outward, in relation to the femur, resulting in a knock-kneed appearance.
The muscle performing an action is the agonist, while the muscle which contraction brings about an opposite action is the antagonist. For example, an extension of the lower arm is performed by the triceps as the agonist and the biceps as the antagonist (which contraction will perform flexion over the same joint).
Jeff Ashton is at home when a mail carrier delivers a strange package. Upon opening the wrapped item, Ashton is horrified to see it contains a severed human arm.He immediately contacts his friend, Doctor Ray Sanders, and the two discuss an incident five years before when, as part of a group of cave explorers, they were trapped by a cave-in.
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 ...
