The results for the average maximum torque for packages and two gripping techniques among all are rized in Grip technique was shown to be a key factor torque transmission when opening CRPs. For all the subjects groups. maximum torque was significantly greater with tridigital prehension than bidigital for all the packages Overall, the transmitted torques of children (3-5 years) were lower than all other groups when opening the three packaging taking each prehension technique separately. Furthermore, the maximum torque measurements of the elderly group were lower when compared to adults (30-59 years). with significant difference found only for the packaging with cylindrical cap Considering the cap design, the greater maximum torques were found in the packaging with inverted conical cap for all groups and both gripping techniques with significant differences when compared to the packaging with conical cap. When it comes to gripping technique. the tridigital torque measurements for the packaging with conical cap were the lowest values for all groups Possibly the main finding of this study is that the torque transmission with tridigital grip for children under 5 years old (the isk group for accidental poisoning) was higher when compared to the bidigital grip for all groups and packages.
