A dynamically tuned gyroscope (DTG) is a rotor suspended by a universal joint with flexure pivots. [57] The flexure spring stiffness is independent of spin rate. However, the dynamic inertia (from the gyroscopic reaction effect) from the gimbal provides negative spring stiffness proportional to the square of the spin speed (Howe and Savet, 1964 ...
Initial symptoms include restlessness, agitation, malaise, or a fixed stare. Then comes the more characteristically described extreme and sustained upward deviation of the eyes. In addition, the eyes may converge, deviate upward and laterally, or deviate downward.
Rigid spine syndrome, also known as congenital muscular dystrophy with rigidity of the spine (CMARS), is a rare and often debilitating neuromuscular disorder.It is characterized by progressive muscle stiffness and rigidity, particularly in the spine, which can severely limit mobility and impact quality of life.
[9] [10] This occurs ~2 1/2 months following injury, without associated neurological symptoms or pain, and typically resolves within 1 year. [ citation needed ] This sign is also sometimes seen as part of a " discontinuation syndrome " associated with certain psychotropic medications, such as selective serotonin reuptake inhibitors and ...
Sacroiliac joint dysfunction is an outcome of either extra-articular dysfunction or from intraarticular dysfunction. SI joint dysfunction is sometimes referred to as "sacroiliac joint instability" or "sacroiliac joint insufficiency" due to the support the once strong and taut ligaments can no longer sustain.
The main differential diagnosis is polymyalgia rheumatica (PMR), although pain, stiffness and weakness at the level of the shoulders and pelvic girdle with associated systemic symptoms (fever, malaise, fatigue, weight loss) is more typical of PMR.
In a May 23 interview with Vogue, the singer, who now knows she has stiff person syndrome, recalled the early signs and symptoms of the rare neurological disorder. It was 2008 and Dion was on her ...
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]
