This is an issue that deserves attention, as research examining iron levels in Americans shows that more people have iron levels that are considered too high, than levels that are deficient. In one study of more than 1,000 people, only 3 percent were iron deficient, but 13 percent had iron overload. 1. What are the Health Risks of Too Much Iron?
Think rigid. Rigidity is a condition of hardness, stiffness or inflexiblity. You find this with muscle contractures. Now think spastic. Spasticity is a form of muscular hypertoncity (excessive muscle tone) with increased resistance to stretching. It usually occurs in the flexor muscles of the arms and legs. You would see movement that requires greater effort and with a lack of control and coordination.
Spasticity is a condition in which muscles are tight or stiff. For example, your hand may stay clenched in a fist or your knee may be hard to bend. At times the muscles may jerk or spasm uncontrollably.It can interfere with your ability to move, speak, or walk normally.pasticity usually occurs because of damage to the part of the brain or spinal cord that controls voluntary movement. It's often the result of a spinal cord injury, a stroke, or a disease such as multiple sclerosis, cerebral palsy, or amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease).
