3.4. Comparison of thumb postures and movements between gender and between subjects with and without musculoskeletal symptoms
Thumb movement differences were seen between subjects with symptoms compared to subjects without symptoms, though none of these differences were statistically significant (Table 4). The subjects with symptoms moved the thumb faster, took fewer and shorter pauses than the subjects without symptoms. Similar to the muscular activity results there were no differences in thumb movements between the different groups of diagnosis compared to the healthy group.
There were also some gender differences with females working in larger abduction, moving the thumb with higher velocity and taking fewer pauses than males; however none of these differences were statistically significant.
