BACKGROUND chronological age is widely used as a marker of frailty in clinical practice. However there can be wide variation in frailty between individuals of a similar age. Grip strength is a powerful predictor of disability, morbidity and mortality which has been used in a number of frailty scores but not as a single marker of frailty. OBJECTIVE to investigate the potential of grip strength...

BACKGROUND Grip strength is a variable which may be important to measure and follow in various populations. A new dynamometer with high accuracy and sensitivity has recently been developed to assess grip strength. The objectives of this work were to provide norms of maximal isometric grip strength measured with this new dynamometer (the MyoGrip device), to assess the reliability of measurements...

The aim of this study was to assess the acute adverse effects (neurotoxic) of several antiepileptic drugs (clonazepam, lamotrigine, oxcarbazepine, phenytoin, phenobarbital and topiramate) by measuring skeletal muscular strength in mice using the grip-strength test. Linear regression analysis of grip-strength in relation to drug dose-response allowed us to determine D(50) values, the dosages of ...

The hand grip test has been correlated with mobility and physical performance in older people and has been shown to be a long-term predictor of mortality. Implementation of new strategies for enhancing healthy aging and maintaining independent living are dependent on predictable preclinical studies. The mouse is used extensively as a model in these types of studies, and the paw grip strength te...

Age-related decline in grip strength predicts later life disability, frailty, lower well-being and cognitive change. While grip strength is heritable, genetic influence on change in grip strength has been relatively ignored, with non-shared environmental influence identified as the primary contributor in a single longitudinal study. The extent to which gene-environment interplay, particularly g...

Grip strength, an indicator of muscle strength, has been shown to be a predictor of poor outcomes among older adults. Protein carbonylation, an indicator of oxidative damage to proteins, leads to cellular dysfunction and a decline in tissue function. Oxidative stress has been implicated in the pathogenesis of sarcopenia. The objective was to determine whether serum protein carbonyl concentratio...

BACKGROUND the European Working Group on Sarcopenia in Older People has developed a clinical definition of sarcopenia based on low muscle mass and reduced muscle function (strength or performance). Grip strength is recommended as a good simple measure of muscle strength when 'measured in standard conditions'. However, standard conditions remain to be defined. METHODS a literature search was c...

OBJECTIVE The purpose of this study was to establish test-retest reliability values for the newly designed grip and wrist attachments of the BTE Primus and to determine criterion-related validity of the new grip attachment against the Jamar dynamometer. An additional purpose was to explore the differences in grip and wrist flexion strength between wheelchair users and control participants witho...

BACKGROUND Many countries are experiencing an aging workforce with women workers making up a growing proportion. Workplaces often require employees to complete lifting tasks that require the ability of the hand to grasp an implement (coupling). The National Institute for Occupational Safety and Health (NIOSH) has developed an equation for manual lifting tasks hoping to minimize the potential fo...
