Eighteen co-ordination postures with shoulder flexion angles (0°, 45° and 90°) and elbow flexion angles (0°, 45° and 90°) in standing and sitting positions were evaluated to identify the effects of co-ordination postures on maximum grip strength and muscle activities of the upper limb in this study. Thirty-nine subjects were recruited and their maximum grip strengths were measured. According to...

BACKGROUND Measuring and comparing grip and pinch strengths with their normative data is a valid method to detect intensity of the numerous damages of hand. This research was carried out with the aim of establishing normative data of grip strength and three types of pinch strengths (Tip, Key and Palmar) in healthy Iranian adults. METHODS In this cross-sectional study, the study population was...

The purpose of this study was to evaluate the effect of gender and grip span (45, 50, 55, 60, 65, 70, 75mm) on resultant force, Individual finger force and subjective discomfort rating. A total of 16 participants (8 males, 8 Females) were participated in this study. All participants were asked to exert a maximum grip force with three repetitions, and to report the subjective discomfort rating f...

UNLABELLED The aim of this study was to provide norms for grip strength in children. A total of 530 Swedish 4-16-y-olds was tested with the instrument Grippit. The instrument estimates peak grip strength over a 10s period, and sustained grip strength averaged across the 10s. The increase in grip strength with age was approximately parallel for boys and girls until 10 y of age, after which boys ...

UNLABELLED Grip strength dynamometers often are used to assess hand function in children. The use of normative grip strength data at followup is difficult because of the influence of growth and neuromuscular maturation. As an alternative, infant welfare centers throughout the world use growth diagrams to observe normative growth. The aim of this study was to develop similar growth diagrams for ...

The aim of this study was to identify questions that could estimate grip strength. Twenty-six questions about the degree of perceived difficulty performing manual tasks as well as two questions concerning self-rated grip strength were developed and completed by 123 community-dwelling older adults, followed by grip strength measurements using a Martin vigorimeter. Multiple regression analyses wi...

BACKGROUND Grip strength in early adulthood and midlife is an important predictor of disability, morbidity and mortality in later life. Understanding social patterning in grip strength at different life stages could improve insight into inequalities in age-related decline and when in the life course interventions could prevent the emergence of inequalities. METHODS Using United Kingdom Househ...

OBJECTIVES Grip strength has been used as a measure of function in various health-related conditions. Although grip strength is known to be affected by both physical and psychological factors, few studies have looked at those factors comprehensively in a population-based cohort regarding elderly Koreans. The aim of this study was to evaluate potential factors influencing grip strength in elderl...

Few studies have investigated the control of grip force when manipulating an object with an extremely small mass using a precision grip, although some related information has been provided by studies conducted in an unusual microgravity environment. Grip-load force coordination was examined while healthy adults (N = 17) held a moveable instrumented apparatus with its mass changed between 6 g an...
