Depiction of a drop attack. A drop attack is a sudden fall without loss of consciousness.Drop attacks stem from diverse mechanisms, including orthopedic causes (for example, leg weakness and knee instability), hemodynamic causes (for example, transient vertebrobasilar insufficiency, a type of interruption of blood flow to the brain), and neurologic causes (such as epileptic seizures or ...
Rewarming shock (or rewarming collapse) is a sudden drop in blood pressure in combination with a low cardiac output which may occur during active treatment of a severely hypothermic person. [ 68 ] [ 69 ] There was a theoretical concern that external rewarming rather than internal rewarming may increase the risk. [ 2 ]
Atonic seizures can occur while standing, walking, or sitting, and are often noticeable by a head drop (relaxing of the neck muscles). Fall injuries may result in impact to the face or head. As with common epileptic occurrences, no first aid is needed post-seizure, except in the instances where falling injuries have occurred.
In upper cross syndrome, the muscles in the front of the body, such as the chest and neck flexors, become tight and overactive. The muscles in the back of the body, including the upper trapezius ...
[9] [1] When the head is elevated above the feet the pull of gravity causes blood pressure in the head to drop. This is sensed by stretch receptors in the walls of vessels in the carotid sinus and aortic arch. [9] These receptors then trigger a sympathetic nervous response to compensate and redistribute blood back into the brain.
That causes an intensely painful tearing chest pain that can radiate to the back, Blankstein says. Lala adds: "That's a very strong pain that feels like something's ripping inside of you.
Adopting a forward head and rounded shoulders posture places increased stress on the neck (cervical spine), mid-back (thoracic spine) and low back (lumbar spine), Dr. Halfman explains.
The drop in blood pressure may be sudden (vasovagal orthostatic hypotension), within 3 minutes (classic orthostatic hypotension) or gradual (delayed orthostatic hypotension). [4] It is defined as a fall in systolic blood pressure of at least 20 mmHg or diastolic blood pressure of at least 10 mmHg after 3 minutes of standing.
