For positioning, the child was instructed to stand comfortably in a normal standing position 'as if waiting at the canteen', and to look straight ahead at a pre-determined point on the wall.
This force will act through the body's centre of gravity, and for an average human this is approximately located at 54 % of their height, in line with the front of their knee/ankle joints in a normal standing posture [24, 30].
Kissing is an intimate experience; while leaning in for a kiss in the beginning is normal, standing sort of far away with only your lips touching might come across as a bit odd.
First, we collect the sensor values in several device's position (normal standing, inclined, jostled, etc).
models with a massless support structure showed best agreement with the measured apparent mass and phase, with errors less than 0.1 in the normalised apparent mass (i.e., corresponding to errors less than 10% of the static mass) and errors less than 5° in the phase for a normal standing posture.
The aim of experiment 2 was to document how a noxious heat stimulation inducing a perception of pain would alter the regulation of postural stability in normal quiet standing.
Holding dumbbells in each hand, slowly raise yourself to tiptoe, and lower yourself slowly to the normal standing position.
Lean back, and kick down to a normal standing position.
