“…The researchers have commonly used electrogoniometry and electromyography (EMG) techniques for evaluating discomfort and muscle activity during physical work involving high repetition, force, or awkward postures (Afshari, Motamedzade, Salehi, & Soltanian, ; Bano, Mallick, & Khan, ; Farooq & Khan, ; Maity et al, ). A. K. Singh, Meena, Chaudhary, and Dangayach () opined that the assessment of limb movements is an essential evaluation measure for designing hand tool interventions by focusing on the path of movement of the tool.…”

The aim of this study is to evaluate several weaving knife configurations in response to multiple criteria's for optimum design. Nine different knife combinations were tested over ten female weavers in a field experiment. Three levels of blade width and angular orientations were taken as the independent variables. Output response about goniometry and electromyography were taken as dependent variables. Multivariate analysis was carried out to estimate the effect of independent variables on output responses. To tackle the difficulty of knife selection with several output responses, three multicriteria optimization approaches have been compared. Multivariate analysis of variance results showed that the effect of both blade width and angle were significant at wrist angles. Also, the magnitude of effect size on both blade width and the angle was highest for the wrist angles. Despite the same weighing criteria, a slight difference was evident between the ranks from optimization methods. The higher blade widths and smaller angular orientations should be recommended for reduction of wrist deviation and muscle activity during weaving. The best possible combination of knife evaluated using multicriteria optimization was 25 mm × 100°.

This study was to investigate the effects of grip force, frequency, stroke rotation and grip-span on discomfort and obtain best posture for hand tool users. Fifteen male participants volunteered in this study. Participants performed combined gripping with torqueing exertions for 5 min for two levels of frequency (10 and 20 exertions/min) at two levels of grip force (50 and 70 N), two levels of stroke rotation (30(○) and 60(○)) and three levels of grip-span (4.7, 6 and 7.3 cm). Therefore, a 2×2×2×3 full factorial design was used. The analysis of variance (ANOVA) showed that frequency, stroke rotation and grip-span were significant on discomfort score. Minimum discomfort and comfortable posture was found to be 90 N grip force with 10 exertions/min for 60° stroke rotation at 6-cm grip-span. The grip force, frequency and stroke rotation were found significant on EMG activity of forearm muscles using multivariate analysis of variance (MANOVA). The extensor muscles were found more activated than flexor muscles during the given task.
