A Basic Primer of the Effect of Stroke on Fine Motor Control
Every forty seconds, someone in the world is suffering from a stroke. Two thirds of the victims survive, mostly from an Ischemic stroke which accounts for 87% of all strokes.
What is an Ischemic Stroke?
An ischemic stroke occurs when there is an obstruction (blood clot) in the blood vessel supplying blood to the brain. Ischemic strokes are not to be confused with Transient Ischemic Attack (TIA) where the obstruction is temporary (an average of a minute) and cause no permanent brain injury.
An ischemic stroke limits blood flow to the brain damaging it. Aside from paralysis, speech defects, and vision problems, ischemic strokes can also impair the body’s fine motor control. Among all impairments stroke victims suffer from, fine motor control is one of the hardest to rehabilitate.
Without proper supervisions, stroke patients find the rehabilitation exercises for fine motor skills to be too demanding and repetitive with frustrating results that they quit halfway.
Fine Motor Control
Fine motor control is the coordinated movement of our skeletal, muscular, and neurological body functions. An example of a fine motor skill is picking up a coin, tying a shoelace, or typing on a keyboard. Stroke patients who have difficulty in performing these kinds of activity suffer a condition called hemiparesis.
There are two common kinds of hemiparesis; Pure Motor Hemiparesis and Ataxic Hemiparesis Syndrome. Pure motor hemiparesis is the most frequent type where stroke victims have face, arm, and leg weakness. Ataxic Hemiparesis Syndrome is the weakness or clumsiness of the body on one side.
Exercise and Stroke Rehabilitation (Part 2)
The following exercises are for patients only moderately affected by their stroke. They may use a wheelchair to move or they might be able to walk with the aid of another person or using a walking aid. However, patients often “lead” with their unaffected side, leaving the other side behind. Therefore, balance problems are likely to appear along with difficulty shifting weight toward the affected side.
The purpose of this exercise program is to:
- Promote flexibility and relaxation of muscles
- Help return to more normal movement
- Improve balance and coordination
- Decrease pain and stiffness
- Maintain range of motion in the affected arm and leg
Spasticity after stroke
After suffering a stroke, many people experience post-stroke spasticity, which is a muscle control disorder that is characterized by tight or stiff muscles and an inability to control those muscles. It impairs not only the mobility, but also impacts the life of their family and caregivers.
Depending on where it occurs, it can result in an arm being pressed against the chest, which can seriously interfere with the ability to perform daily activities such as dressing. One may also suffer from spasticity in the leg, which may cause a stiff knee or a pointed foot and curling of the toes that interferes with walking. It can also be accompanied by painful muscle.
