“…Another study found that the maximum grip strength can be obtained at a handle inter distance between 50 mm and 60 mm [117]. Recent studies revealed that handles inter distance of 47.6 to 60 mm provides the maximum hand grip strength [49], [118]. On the other hand, too large or too small handles inter distance will be problematic for some users thus affect their grip strength.…”

“…Several hand tools have been studied to investigate their effects on the hand grip strength. Examples includes screw drivers [45]; hand wheels [46]; staple gun [47]; powered hand drill [48]; pliers [49], [50]; carpet weaving tools [51]; pruning shears [52] and files [53]. Even though studies on ergonomically design hand tools have gained superior attention from the researchers around the world, the information on the detail factors of hand tool design which affecting the hand grip strength requires further compilation work as they are now available in scattered publications i.e.…”

Hand is made up of bones, tendons, ligaments, nerves and blood vessels that can be easily debilitated and injured if the hand tool is not design ergonomically. Recently researchers have examined the effects of individual, environmental and occupational factors on hand grip strength. However, information on the influence of hand tool design on hand grip strength is still lacking. The aim of this paper is to provide a comprehensive review of factors influencing hand grip strength focusing more towards hand tool design factors. The authors searched the journal articles, book and guidelines from the online databases of Google Scholar, ScienceDirect and Pubmed. Fourteen factors includes handle diameter, handle length, handle orientation, handle shape, handle material, handle flange, handle inter distance/grip span, grip method, tool weight, tool center of gravity, tool sharpness, trigger type and size, spring stiffness as well as vibration exposure were found to have significant effect on the hand grip strength. This review identified that the handle diameter is the most significant factor for hand grip strength.

“…The grip force and the relative contributions of different areas of the hand have also been studied for the design of handles (Lee et al, 2009;McGorry and Lin 2007;Kong et al, 2014). Specific devices have been designed for studying the grip force distribution, especially for cylindrical handles (Chadwick and Nicol, 2001;Dong et al, 2008;Rossi et al, 2012) and recently for pliers (Kim et al, 2016). Most of the studies analysing the contributions of different hand areas to the grip force have used cylindrical objects because they can easily be wrapped with thin pressure sensors, such as the Tekscan or Fuji Film pressure mapping systems (Nicholas et al, 2012;Pataky et al, 2012, Wu et al, 2014.…”

Grip force and force sharing in two different manipulation tasks with bottles

et al. 2016

Grip force and force sharing during two activities of daily living were analysed experimentally in 10 right-handed subjects. Four different bottles, filled to two different levels, were manipulated for two tasks: transporting and pouring. Each test subject's hand was instrumented with eight thin wearable force sensors. The grip force and force sharing were significantly different for each bottle model. Increasing the filling level resulted in an increase in grip force, but the ratio of grip force to load force was higher for lighter loads. The task influenced the force sharing but not the mean grip force. The contributions of the thumb and ring finger were higher in the pouring task, whereas the contributions of the palm and the index finger were higher in the transport task. Mean force sharing among fingers was 30% for index, 29% for middle, 22% for ring and 19% for little finger. Practitioner Summary: We analysed grip force and force sharing in two manipulation tasks with bottles: transporting and pouring. The objective was to understand the effects of the bottle features, filling level and task on the contribution of different areas of the hand to the grip force. Force sharing was different for each task and the bottles features affected to both grip force and force sharing.
