Final answer:
The Goodall sign is a clinical finding in patients with paresis or paralysis of one side of the body where they cannot simultaneously move both the arm and leg on the same side.
Step-by-step explanation:
The Goodall sign is a medical term used to describe a clinical finding in patients with paresis or paralysis of one side of the body. It refers to the patient's inability to simultaneously move both the arm and leg on the same side of the body. This is due to the lack of corticospinal control of the muscles involved in the movement.
For example, if a patient is unable to raise their right arm when attempting to kick with their right leg, it would be considered a positive Goodall sign.
The Goodall sign is commonly observed in some neurological conditions, such as stroke, brain tumor, or spinal cord injury.
