When the movement is performed in response to an external stimulus, the same neuron may discharge hundreds of milliseconds before a slow and accurate movement of small amplitude or only 60 ~ 100 ms ([T.sub.A]) before a ballistic movement
Neurologic examination showed facial dyskinesis (grimacing) and a ballistic movement
in her left trunk, arm, and legs.
The plie is a closed-loop movement that relies on proprioceptive updating, while the saute is a ballistic movement
that is more typical of open-loop planning.
To analyze the impact of ballistic movement
on the echo's time-range profile, we choose another time duration of 101-101.1 s randomly as the observing time, and the time-range profile of echo generated by the method proposed in this paper is shown in Fig.
To feel the benefit of ballistic movement
, Harren suggests this sequence: Warm up first and then do some gentle stretching on your calf muscles.
"The outstanding characteristics of the ballistic movement
," according to Mursell, "are first, its speed, second, its ease, and third, its precision.
Control of goal directed motor activities during 'on' periods (when the effect of a drug is working) such as drawing non-geometrical paint strokes, finger painting, cutting paper with scissors, hammering a nail, shooting a basketball, throwing darts, punching a bag, and other ballistic movement
tasks become an integral part of occupational re-education.
Although the basic triple agonist/antagonist/agonist EMG pattern of ballistic movement
is preserved in PD, the initial agonist burst is reduced and the movement appears to take place in series of triple patterns and is thus prolonged (31).
The plie is a closed-loop movement, which allows the performer to consider proprioceptive information, while the saute is a ballistic movement
that relies more heavily on feed-forward planning.
As shown in Figure 5, MT between the moment the head moves and the moment the reticle is resting on the target is the sum of three components: (a) time lag, L, (point A to B); (b) MT of the first ballistic movement
from the starting point to the first stopping point near the target (point B to C); and (c) MT of a series of move-and-wait movements homing into the target (point C to D).
During a stretch, a ballistic movement
will activate a safety mechanism called the stretch reflex - which we don't want to happen, since it inhibits further muscular stretching and produces a contraction.
The garment includes two types of self-powered sensors that detect "ballistic movements
," or pressure changes.
