Table 1 Movement tasks based on Gentile’s taxonomy of tasks[51]
Body stability | |||
|---|---|---|---|
No object manipulation | Object manipulation | ||
⇨ dorsal extension | ⇨ lifting up weight (dorsal extension) | ||
⇨ palmar flexion | ⇨ lifting up weight (palmar flexion) | ||
⇨ ulnar-/radial abduction | ⇨ wiping a table with a cloth | ||
⇨ supination/pronation | ⇨ handling of a bike lock/kitchen timer | ||
No intertrial variability | ⇨ opening and closing hand (like grasping a cup) | ⇨ wringing out a towel | |
⇨ thumb-finger-oppositions | ⇨ compressing a softball | ||
⇨ finger-tapping sequence | ⇨ grasping a pen with little finger (e.g.) and thumb | ||
⇨ playing piano (simple 5-finger-scale) | |||
Stationary environment | |||
⇨ Dorsal extension against different resistances | ⇨ grasping, lifting, turning different cups (size, weight) | ||
⇨ Palmar flexion against different resistances | ⇨ catching different balls on a marple run (reaction) | ||
⇨ Ulnar-/radial abduction against different resistances | ⇨ compressing softballs of different sizes/hardness | ||
Intertrial variability | ⇨ Supination/pronation against different resistances | ⇨ pulling a cloth across the table (ulnar/radial) against different resistances | |
⇨ Swimming in turbulent water | ⇨ bowling/rolling a ball towards a partner | ||
⇨ playing ping-pong | |||
