Motor paralysis: In cerebrovascular accident, due to the influence of the damaged brain area, patients often have motor paralysis of half of the body, including arms, legs, trunk, even the face and other parts of the body. other cranial nerves.
Due to the affected muscle groups in the hand, the motor function of the hand is reduced, causing the patient to be completely or partially paralyzed, affecting activities, in which small muscle groups with functional performance The delicate movements of the hand are often quite severely affected.

Muscle spasticity: After the disease stage, the patient will change from flaccid paralysis to spastic paralysis. Like other muscle groups on the side of the body that is injured, the muscle groups in the child's hand should be stiff, more severe can lead to contractures and joint deformities. As a result, joints such as shoulder, elbow, wrist, and finger joints have limited range of motion, making it difficult to perform normal hand activities
Pain: Along with motor paralysis movement and muscle spasms, pain is a fairly common symptom after a stroke, especially hand pain or upper limb pain.
There are many causes of this pain, the most common include:
Muscle spasticity: muscle tension, stiffness, contracture, joint deformity Sudeck syndrome due to sympathetic dysfunction, hand stiffness edema, decreased activity and pain Shoulder subluxation and shoulder dislocation Neurological pain

These tools will be designed differently from The original original tools of normal people follow the following principles, depending on the patient's mobility.

2.2 Increase the size of the handles of the utensils Because of the reduced fine motor hand movements, the hand tools used by stroke patients are often designed with larger handles to accommodate the person's ability to hold them. sick

2.3 Changing the shape of objects To help with mobility limitations, some objects are designed with different shapes than usual to suit the patient's ability.
