Parkinsonism refers to a group of chronic, progressive disorders that severely impair an individual’s motor control, or ability to activate and coordinate the muscles and limbs used in movement. Impacted motor skills include gross motor skills, which involve the large muscle groups that affect walking, running, balancing, and climbing stairs. They also refer to fine motor skills, which involve small muscle groups such as those that enable grasping, holding, and manipulating small objects.
