static balance

A condition of balance of an aircraft control surface in which the surface balances about its hinge line. Controls are statically balanced to prevent flutter. One of the methods of balancing the control surface is to install lead weights ahead of the hinge line. A propeller is said to be in static balance if it remains in any position when mounted concentrically on knife edges.

This scale consists of 14 items assessing dynamic and static balance. Items evaluate three dimensions: maintaining a posture, adjustment of voluntary movements and reaction to external disturbances.
Static balance testing was performed using a commercially available piezoelectric force plate with a sampling frequency of 1000 Hz (9260AA6, Kistler Instruments, Winterthur, Switzerland).
Thus, the dynamic balance has a more complex mechanism than does the static balance. Balance parameters decrease due to joint movement limitations, muscle strength losses, proprioceptive sensory losses and dynamic.
Both groups also showed improvement on the MFRT, which tests not only static balance, but also reaching with the arms, while maintaining a seated position.
The static balance task induced activation in the right PMC (p = 0.01) and right PFC (p < 0.001) during MI and in the right SMA (p = 0.02) during AO + MI.
The results of the present study revealed increased ST values which indicate a mild impairment of static balance in females with GJL compared to participants without hypermobility.
The differences between percentages of body weight on the right and left foot depicted static balance impairment.
Static balance is defined as the ability to maintain an upright posture and to keep the line of gravity within the limits of the base of support (i.e., quiet standing) [2].
