Objective
To compare stroke-related changes in hip-flexor neuromuscular fatigue of the paretic leg during a sustained, isometric sub-maximal contraction with the non-paretic leg and controls, and correlate fatigue with clinical measures of function.
Design
Hip torques were measured during a fatiguing hip-flexion contraction at 20% of the hip flexion maximal voluntary contraction (MVC) in the paretic and non-paretic legs of 13 people with chronic stroke and 10 age-matched controls. In addition, participants with stroke performed a fatiguing contraction of the paretic leg at the absolute torque equivalent to 20% MVC of the non-paretic leg and were tested for self-selected walking speed (Ten-Meter Walk Test) and balance (Berg).
Results
When matching the non-paretic target torque, the paretic hip flexors had a shorter time to task failure compared with the non-paretic leg and controls (p<0.05). Time to failure of the paretic leg was inversely correlated with the reduction of hip flexion MVC torque. Self-selected walking speed was correlated with declines in torque and steadiness. Berg-Balance scores were inversely correlated with the force fluctuation amplitude.
Conclusions
Fatigue and precision of contraction are correlated with walking function and balance post stroke.
Increased width of high signal has a moderate specificity but a poor positive predictive value for distinguishing a SLAP tear from a normal recess. In addition, labral signal posterior to the biceps tendon is not rare in patients with no SLAP tear.
Purpose -This paper aims to describe the history of cyber security public international law since 1850 that is found in treaty instruments developed by the signatory nations of what is now known as the International Telecommunication Union (ITU). Because of the esoteric nature of the subject and, until recently, the very difficult access to reference materials, knowledge of these provisions was confined to a handful of scholars.Design/methodology/approach -To prepare this article, it was necessary to download the entire new ITU History Portal collection of treaty instruments, adding the US archive collection scans of missing documents, conversion to plain text, identification and linking of key provisions across time, detecting the differences, and then pursuing related material to find out why the text arose.Findings -What the material reveals is a 150-year history of cybersecurity law that is not only relevant to significant developments today, but also controlling as a set of obligations that virtually every nation has accepted.Research limitations/implications -It is hoped that this article will not only be helpful going forward in dealing with the difficult challenges of evolving these provisions, but will also serve as a kind of template for a new generation that not only questions authority, but also appreciates the value of source materials, accessing them, and doing the necessary analysis rather than just visiting a search engine.Originality/value -The history of the cyber security public international law in the international telecommunication treaty instruments has never been compiled before.
The cybersecurity information exchange framework, known as CYBEX, is currently undergoing its first iteration of standardization efforts within ITU-T. The framework describes how cybersecurity information is exchanged between cybersecurity entities on a global scale and how the exchange is assured. The worldwide implementation of the framework will eventually minimize the disparate availability of cybersecurity information. This paper provides a specification overview, use cases, and the current status of CYBEX.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
