It is generally believed that an internal representation of movement variables -such as position and velocity- is maintained in the neural activity (whether in intrinsic joint and muscles or extrinsic coordinates) and used to update and monitor the state of the system.
For relatively unconstrained dynamic head movements, kinematic performance variables such as peak velocity are also lower than in healthy participants [ 10, 11] and the peak head movement displacement is typically reduced in people with chronic WAD [ 10- 17].
The ability of an extruded chocolate fibre to span large distances without collapsing was investigated by adjusting variables such as movement speeds, extrusion rates and cooling rates.
Early work demonstrated that neural firing correlates with external variables such as movement direction (Georgopoulos et al., 1982), and an ongoing debate centers on whether the firing patterns represent muscle or movement parameters (e.g., joint position, intended velocity, reach endpoint, muscle forces, and so on; reviewed in Kalaska, 2009).
Relationships between configuration variables Yeadon enforced relationships between certain configuration variables, such as symmetric movement of the legs with respect to the pelvis.
Without resorting to invasive techniques, the precise assessment of clinically relevant variables, such as intervertebral movements, is difficult to obtain.
Though the lateral flexion ranges in patients with neck pain were reported to be lesser than those in the normal adults, the precise assessment of clinically relevant variables, such as intervertebral movements, is difficult to obtain.
The priors we use for simple one-dimensional variables, such as speed of movement for visual objects [ 3] or direction of sunlight [ 13], have each been carefully characterized in the context of a specific perceptual task.
4 Macroeconomics examines the movements and trends in economy-wide aggregate variables such as employment, inflation, interest rates, money supply and output.
Typically, ecological or evolutionary studies of movement focus on trajectories measured through course-grained variables such as the center of mass [3].
