In extreme cases, the affected person may lose fingers. The effects are cumulative. When symptoms first appear, they may disappear after a short time. If exposure to vibration continues over months or years, the symptoms can worsen and become permanent. [4] Exposure to hand arm vibrations is a respectively newer occupational hazard in the work ...
Typical manifestations include pacing around, wringing of the hands, uncontrolled tongue movement, pulling off clothing and putting it back on, and other similar actions. [1] In more severe cases, the motions may become harmful to the individual, and may involve things such as ripping , tearing, or chewing at the skin around one's fingernails ...
Psychomotor learning is the relationship between cognitive functions and physical movement.Psychomotor learning is demonstrated by physical skills such as movement, coordination, manipulation, dexterity, grace, strength, speed—actions which demonstrate the fine or gross motor skills, such as use of precision instruments or tools, and walking.
Motor skills: Aging causes decreased physical abilities, such as gross and fine motor skills and reflexes, thereby rendering the driver physically unable to perform at a safe level. [ 21 ] [ 22 ] As age increases, there is a reduction in muscle mass and elasticity, bone mass, central and peripheral nerve fibers. [ 23 ]
Motor skill consolidation represents the process by which motor skills are transformed from an initial fragile state, in which they are especially prone to being disrupted or lost, to a more solid or permanent state. [1] Any newly formed motor skill, such as learning to play a musical instrument or adjusting one's running stride, is subject to ...
Exposures and limits have been estimated in the ISO 5349-1 for hand-transmitted vibration. [3] A 2018 meta-analysis said that whole body vibration can improve bone mineral density in the lumbar spine of postmenopausal women as well as the femoral neck density of postmenopausal women younger than 65.

The phrase "if you don't use it, you lose it" is a perfect way to describe these skills, they need to be continuously used. Discrete tasks such as switch gears in an automobile, grasping an object, or striking a match, usually require more fine motor skill than gross motor skills. [3] Both gross and fine motor skills can become weakened or damaged.
Pallesthesia (\ˌpal-es-ˈthē-zh(ē-)ə\), or vibratory sensation, is the ability to perceive vibration. [1] [2] This sensation, often conducted through skin and bone, is usually generated by mechanoreceptors such as Pacinian corpuscles, Merkel disk receptors, and tactile corpuscles. [1]
