Glaucoma – ‘A Stiff Eye in a Stiff Body’

Current Eye Research, 2022
Glaucoma is a progressive, age-related optic neuropathy, whereby the prevalence increases sharply over the age of 60 and is associated with increased systemic tissue stiffness. On a molecular basis, this is associated with increased deposition of collagen and loss of elastin structure, resulting in aberrant biomechanical compliance and reduced tissue ...

On the stiffness and stiffness control of redundant manipulators

Proceedings 2002 IEEE International Conference on Robotics and Automation (Cat. No.02CH37292), 2003
An analysis of the stiffness of redundant manipulators is undertaken in this paper. First, the matrix of the force-dependent stiffness is derived and its basic properties are analyzed. In particular, in the planar case the stability conditions for the force dependent stiffness (and gravity-dependent stiffness) are obtained in the analytical form. Next,

STIFF EYES IN STIFF-PERSON SYNDROME

Neurology, 2008
The clinical findings of stiff-person syndrome (SPS) include trunk and limb muscle stiffness and paroxysmal cramps. Antibodies directed against glutamic acid decarboxylase (GAD) has been associated with SPS. We report a patient with SPS and anti-GAD antibodies (antiGAD-Abs) with a prominent supranuclear gaze palsy and bradykinesia mimicking progressive

Arterial stiffness

Journal of Hypertension, 1999
Arterial stiffness is an important determinant of pulse pressure, and of left ventricular load and coronary perfusion pressure.Precise quantification is elusive, since stiffness is different in different arteries and even in the same artery at different pressures.

Shoulder Stiffness

Arthroscopy, 2008
Abstract Shoulder stiffness is commonly encountered in clinical practice but varies greatly in severity and etiology. Loss of shoulder range of motion can be a patient's primary complaint or may be a secondary finding. Possible causes of stiffness include guarding due to pain or secondary gain issues (nonanatomic), true mechanical ...
