Toothbrushing is fundamental to oral hygiene. Children differ in manual dexterity and their grip on toothbrushes. We videotaped toothbrushing sessions and observed the grip type, duration of brushing, and brushing technique used among 100 children aged 8-12 years. We then investigated the association between grip type and plaque removal, using plaque scores obtained at various time points. We f...

This experiment was designed to know the effect of upper limb postural deviations on grip strength and grip endurance time. A full factorial design of experiment, i.e., 3 (0°, 45°, 90° abduction angles of upper arm) × 3 (45°, 90°, 135° angles of elbow flexion) × 3 (0°, -60° prone, +60° supine angles of forearm rotation) was used to find the effect of 27 combinations of postures on maximum volun...

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...

Grip strength is affected by such as enslaving effect, force sharing effect, and force deficit effect relating to the interaction among fingers. The author attempts to analyze index finger strength according to grip span of adjacent middle finger. 6 male graduate students participated as subjects in this experiment. The grip span has been applied from 45 mm to 60mm to investigate the effects of...

The aim was to investigate differences of the kinetics of the crimp and the slope grip used in rock climbing. Nine cadaver fingers were prepared and fixated with the proximal phalanx in a frame. The superficial (FDS) and deep (FDP) flexor tendons were loaded selectively and together with 40 N in the crimp grip (PIP joint flexed 90°/DIP joint hyperextended) and the slope grip position (<25° flex...

background: it is widely recognized that neuromuscular function is temperature sensitive. changes in muscle temperature may affect muscle force development. the aim of this study was to investigate the effects of temperature on wrist flexor muscles endurance. methods: fifteen healthy subjects (mean age  21.13 ±1.30 years) participated in the present study.  the wrist flexor muscles endurance wa...

purpose the purpose of this study was to estimate the dominant handgrip strength and its correlations with some hand and arm anthropometric variables in 101 randomly selected indian inter-university female volleyball players aged 18-25 years (mean age 20.52±1.40) from six indian universities. methods three anthropometric variables, i.e. height, weight, bmi, two hand anthropometric variables, vi...

BACKGROUND Strain, and particularly Longitudinal Peak Systolic Strain (LPSS), plays a role in investigating the segmental and overall contractility of the heart which is a particularly interesting feature in athletes in whom regular training determines several morphological and functional modifications in both the ventricles, that normally work at different loads. Speckle tracking techniques as...

INTRODUCTION The hand grip strength test provides useful and reliable information about overall health. Different studies have investigated the optimal grip span for determining maximal hand grip strength in different populations such as adults, adolescents and children without disabilities. OBJECTIVE To ascertain whether there is an optimal grip span for determining maximal hand grip strengt...

A common complaint among patients with burns is their inability to grasp items while wearing compression gloves. Recent technological innovations permit the addition of grip-enhancing material to garment fabric. The purpose of this case series was to describe the course of development of compression gloves with enhanced grip modifications. Five different types of grip modifications were made du...
