For this experiment, we expected to record kinematics from the legs through the whole stand and sit task.
The result that the sit task was more difficult than the biped or cling task could be explained by the fact that this was the first task animals were confronted with.
However, we obtained similar results using the Z-score or the Binomial test in the decision whether a subject was ambiguous, right- or left-handed (only one subject changed from ambiguous to right-handed for the sit task).
Table 2 also shows a marginally significant effect for the PII (F 2,50) = 3.01; p = .055), and PIx3 concerning the high frequency band (F 2,50) = 2.99, p = .056); these parameters trended to be higher for the SFT than for the FT and SIT tasks.
For the FGT-sit task the opening of the transparent box was fixed at a distance of 1.5 cm from the wooden bar.
Further, the FGT-sit task was significantly more difficult than the FGT-biped and FGT-cling task (Wilcoxon-test: sit versus biped: T = 11.86, n = 26, p = 0.019; sit versus cling T = 8.4, n = 27, p < 0.001), whereas there was no significant difference between the FGT-biped and FGT-cling task (Wilcoxon-test: T = 13.22, n = 26, p = 0.151).
In the FGT-sit task, 42 of the subjects (N = 54; 77.8%; Table 1) showed an individual hand preference by using one hand significantly more often than the other (Binominal test: p ≤ 0.05): 24 subjects were right-handed and 18 subjects were left-handed.
It was replaced with "controlled assessment" – extended tasks sat under supervision with students allowed to consult notes.
Furthermore, recent data confirm that coordination of the abdominal muscles can be restored with training of specific activation of the trunk muscles, but not a simple activation during a sit up task [ 30].
Four subscales are derived from the questionnaires: a) Oppositional (e.g., breaks rules, gets annoyed or angered), b) Hyperactivity (does not sit still, task persistence, restlessness, impulsivity), c) Cognitive Problems/Inattention (learns slowly, disorganized, cannot concentrate), and d) ADHD Index.
