Eight subjects with carpal tunnel syndrome (CTS) (47.13 ± 7.83 years) and 8 matched controls (46.29 ± 7.27 years) manipulated a test object fitted with an accelerometer and force sensor, both before and after hand muscle fatigue. Grip force and object acceleration were recorded and used to calculate grip force control variables that included Grip Force Peak, Safety Margin, and Time to Grip Forc...

To reduce the risk of slip, grip force (GF) control includes a safety margin above the force level ordinarily sufficient for the expected load force (LF) dynamics. The current view is that this safety margin is based on the expected LF dynamics, amounting to a static safety factor like that often used in engineering design. More efficient control could be achieved, however, if the motor system ...

The decrease of “functional” endplate receptors in MG can decrease the response to the chemical transmitter acetylcholine, as well as to the depolarizing muscle relaxant succinylcholine. In contrast, the decreased “safety margin” results in a marked sensitivity to nondepolarising relaxants. In normal patients, the wide “safety margin” may explain the slow onset of nondepolarizing block, as well...

This study is devoted to seismic collapse safety analysis of performance based optimally seismic designed steel chevron braced frame structures. An efficient meta-heuristic algorithm namely, center of mass optimization is utilized to achieve the seismic optimization process. The seismic collapse performance of the optimally designed steel chevron braced frames is assessed by performing incremen...

Background: Mentha longifolia is one of the aromatic medicinal plant belongs to Lamiaceae family. There are some active ingredients in the essential oil of M. longifolia, which potentially could impair the hepatic function. The aim of this study was to find the maximum dose of essential oil of M. longifolia (EOML) that does not show any hepatic deterioration. Methods: Adult Wistar rats fed d...
