The acquisition task required participants to move a horizontal lever (with 0.567 kg load) to 16 sequentially projected targets.
But the picture is that we have a sense of how the pore closes simple mechanical device with these little horizontal lever helices that can push down on it.
Recommendations for check reading or resetting purposes arising out of this study are that for a horizontal lever the display pointer should be at 12 o'clock, and for a vertical lever the pointer should be at 9 o'clock.
However, larger femoral heads have been considered to cause an increase in the effective horizontal lever arm, which imparts greater torsional forces at the head neck junction [9] (Table 1).
Figure 3 shows how this effective horizontal lever arm (HLA) distance was calculated.
The ankle was secured in 90° flexion with an ankle-foot orthosis to a load cell on the horizontal lever arm of the dynamometer, and the tibiofemoral joint directly above, and intersected by, the lever arm axis of rotation, thus ensuring a gravity-neutral position.
