The first, fumbled attempts to make contact were the reason for my uncoordinated limb movements.
The entire muscle-tendon system works cohesively to slow down limb movement.
Although periodic limb movement is considered a separate condition, it often happens to people who have restless legs syndrome.
It is also modulated even in the absence of visual feedback from the limb movement.
Periodic limb movements may also occur during the day, although most people move around after their legs begin to bother them.
Around this time, limb movements become more complex, with flexing of the joints and ribs.
In one study it was found that the putamen controls limb movement.
In the older figures, a fast limb movement would cause the entire figure to shake in an unnatural way.
As a result, the periodic limb movements that people have when they are awake may not be noticed except under unusual circumstances.
Both problems also become increasingly common with age; more than 30 percent of people over 65 are plagued by periodic limb movements during sleep.
