P5.19 STIFF ARTERIES, STIFF HEARTS?

open access: yesArtery Research, 2013
Objectives: To examine the relationship between arterial stiffness and diastolic function in healthy normotensive subjects. Methods: For this study, 43 male (40±10 years) and 64 female (40±9 years) subjects were recruited. All were lifelong non-smokers, normolipidaemic, normoglycaemic and had normal 24-hour blood pressure responses (SBP\DBP <140\90).

Does shear wave ultrasound independently predict axillary lymph node metastasis in women with invasive breast cancer? [PDF]

open access: yes, 2013
Shear wave elastography (SWE) shows promise as an adjunct to greyscale ultrasound examination in assessing breast masses. In breast cancer, higher lesion stiffness on SWE has been shown to be associated with features of poor prognosis.

A Method for Quantifying Stiffness of Ankle-Foot Orthoses Through Motion Capture and Optimization Algorithm

open access: yesIEEE Access, 2022
Adjustments of Ankle-Foot Orthosis (AFO) stiffness is commonly prescribed for people with neurologically impaired to improve walking. It is important to quantify AFO stiffness levels to provide consistent patient-specific settings.

The Stiff Elbow [PDF]

open access: yesHAND, 2009
Elbow motion is essential for upper extremity function to position the hand in space. Unfortunately, the elbow joint is prone to stiffness following a multitude of traumatic and atraumatic etiologies. Elbow stiffness can be diagnosed with a complete history and physical exam, supplemented with appropriate imaging studies.

Is High-frequency stiffness a measure for the number of attached cross-bridges? [PDF]

open access: yes, 1996
Muscle stiffness is an important property for movement control. Stiffness is a measure for the resistance against mechanical disturbances in muscular-skeletal systems.

Using stiffness to assess injury risk:comparison of methods for quantifying stiffness and their reliability in triathletes [PDF]

open access: yes, 2018
Background: A review of the literature has indicated that lower body stiffness, defined as the extent to which the lower extremity joints resists deformation upon contact with the ground, may be a useful measure for assessing Achilles injury risk in ...

Coupling with adjustable torsional stiffness [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2021
This study presents a novel coupling design with adjustable torsional stiffness. Since the torsional stiffness of the coupling can be adjusted, it can potentially be applied to tune the torsional natural frequencies of rotating systems.

Low Temperature Performance Characteristics of Reclaimed Asphalt Pavement (RAP) Mortars with Virgin and Aged Soft Binders

open access: yesApplied Sciences, 2017
Reclaimed asphalt pavement (RAP) has many advantages and is utilized to improve the high temperature properties of asphalt mixtures. Low temperature cracking is a predominant distress in asphalt pavements containing RAP materials. Thus, the evaluation of
