❌ -- Underestimation of distance or range needed to accomplish a movement ❌ -- Decrease in muscle tone ❌ -- Generalized muscle weakness ❌ -- Rhythmic, quick oscillatory, back-and-forth movement of the eyes ❌ -- Movement performed in a sequence of component parts rather than as a single, smooth activity; decomposition ❌ -- Inability to halt forceful movements after resistive stimulus removed; patient unable to stop sudden limb motion ❌ -- Impaired ability to perform rapid alternating movements ❌ -- Disorder of the motor component of speech articulation ❌ -- Loss of ability to associate muscles together for complex movements ❌ -- Overestimation of distance or range needed to accomplish a movement ❌ -- Inability to judge the distance or range of a movement

Which of the following are examples of motor impairments caused by BASAL GANGLIA pathology?

"A number of specific motor impairments that affect coordinated movement are associated with cerebellar basal ganglia( cerebellar, basal ganglia ) pathology. Many of these impairments either directly or indirectly influence the patient's ability to execute accurate, smooth, controlled movements." -O'Sullivan 6th ed.
"Patients with lesions of the basal ganglia cerebellum( basal ganglia, cerebellum ) typically demonstrate several characteristic motor deficits: 1.) poverty and slowness of movement, 2.) involuntary, extraneous movement, and 3.) alterations in posture and muscle tone." -O'Sullivan 6th ed.
Which of the following are characteristic impairments of UMN lesions?
Hypertonia
Velocity dependent changes in muscle tone
Hyperreflexia
Muscle Spasms
Hypotonia
Non-Velocity dependent (i.e. Velocity-Independent) changes in muscle tone
Hyporeflexia
Fasciculations
Which of the following are characteristic impairments of LMN lesions?
Ipsilateral Weakness or Paralysis, in all cases.
Weakness and Paralysis are always focal.
Neurogenic Atrophy
Ipsilateral Weakness or Paralysis, in some cases, but not all.
Bilateral Weakness or Paralysis, in some cases, but not all.
Contralateral Weakness or Paralysis, in some cases, but not all.
Weakness and Paralysis are always distributed, never focal.
Wide-spread Disuse Atrophy
Sensation may be impaired by lesions in which of the following locations?
Cerebral Cortex - Corticospinal Tracts
