Repeat this imagery task 10 times before moving onto the next imagery task. Squeeze your fingers and thumb hard enough to lift the pen off the table.

Think about opening your fingers and thumb just wide enough to grasp the pen. Open your fingers and thumb as your hand approaches the pen on the table.Straighten your elbow as you reach for the pen.Bring your arm forward slowly toward the pen.Imagine yourself sitting up tall in a chair with your arm on the table.Today we are going to imagine that you are reaching for a pen that is sitting on a table in front of you.Using a knife to spread peanut butter onto bread.Grabbing a tissue and bringing it up to the nose.Reaching for a towel and drying the other arm with it.Picking up a pen and positioning it in the hand for writing.Mental imagery scripts can be composed for many different activities depending on the client’s goals. The therapist provides specific instructions describing the activity to be imagined, including the specific upper extremity movements required to complete the task, the number of repetitions or the duration of the activity. At the same time, position the client’s affected upper extremity in the correct position for the start of the movement that is to be imagined. The client is instructed to imagine all of the steps of a successful task or activity. Ideally, imagery is often done either immediately before or after practicing actual movements of the affected upper extremity. Mental imagery is best done in a quiet environment so distractions are minimized.

Theoretically, with findings similar to the above, one can assume that if mental simulation of action excites neural activations of corresponding motor areas, then the potential exists to reorganize the brain in the absence of movement execution. Because of the encouraging evidence, using mental practice as a neuro-rehabilitation technique is becoming more widely used in the clinical community. Recent research now shows that rehabilitation programs that include mental practice in therapy have the potential to increase outcomes in motor impairment and functional rehabilitation significantly. Mental Practice and Stroke Rehabilitation Moreover, just observing movement has been shown to activate cortical motor areas ( Grezes and Decety, 2001). Therefore, overtime, repeated use of mental practice may provide some of the same benefits as physically rehearsing a task. Studies by Decety and colleagues (1996) have shown that imagery of movement activates largely the same brain areas that are activated when movements are actually executed. Studies demonstrate that during mental practice intervention the same brain areas are as activated as during functional tasks. The reason that this technique works so well seems to be because, when we mentally rehearse an activity, the same muscles are activated as if we are actually performing the activity. Mental practice has been proven to be effective for athletes and musicians in improving their motor and skill performance. Increased awareness has been raised by the potential of mental practice of motor tasks, also called ‘motor imagery’, as a way of improving motor recovery following stroke. Mental practice is described as the rehearsal of a physical activity in the absence of any physical movement. In general, the less damage there is to the brain tissue, the greater the chances of a successful recovery. One’s overall recovery mainly depends on the location and amount of brain damage caused by the stroke, the ability of other healthy areas of the brain to take over functioning for the damaged areas, and rehabilitation. While some may see improvement early on, others may require months or years of therapy before meaningful progress can be made. Recovering from a neurological injury, such as stroke, can be challenging and unpredictable. This depends on where and how much of the brain is damaged and how fast the blood supply can be returned to the affected cells. The loss of function may be mild or severe and temporary or permanent. When brain cells are damaged or die, the body parts controlled by those cells cannot function. After about 4 minutes without blood and oxygen, brain cells become damaged and may die. With a hemorrhagic stroke, there is bleeding in the brain. Eighty percent of all strokes occur due to ischemia. When you have an ischemic stroke, there is an interruption, or reduction, of the blood supply. A stroke is the rapid loss of brain function(s) due to disturbance in the blood supply to the brain.
