What is a way to test UE coordination?
An individuals ability to maintain their line of gravity within their base of support
What is balance?
Influences movement through its connections to other motor structures
What does the cerebellum do?
The name of the inner fiber tracts of the cerebellum
What are the arbor vitae?
Enters the cerebellum via the inferior cerebellar peduncle
What are the ascending fibers of the dorsal spinocerebellar tract?
Rapid alternating movements while turning hands over or toe-tapping synchronously
What is RAM?
The area beneath an object or person that includes every point of contact that the object or person makes contact with the supporting surface

What connects the 2 hemispheres of the cerebellum?
Descends into the cerebellum via the superior cerebellar peduncle
What are the axons of the ventral spinocerebellar tract?
Heel-to-shin
What is a way to assess LE coordination?
The ability to activate muscles in the legs and trunk for balance control in advance of potentially destabilizing voluntary movements
What is anticipatory balance?
Reducing the amount of joints that are moving simultaneously (tucking elbows/upper arms against the body when using hands)
What are ways to constrain degrees of freedom?
The 3 lobes of the cerebellum
What are named anterior, posterior, and flocculonodular?
Mossy & climbing fibers
What are two of the afferent fibers that travel to the cerebellar cortex?
Occurs when one arm and palm turn inward and downward
What is pronator drift?
The last line of defense to prevent a fall when the body loses stability

Recent studies have shown that ___ may help facilitate residual cerebellar function
What is transcranial direct current stimulation of the cerebellum?
The 3 cerebellar peduncles
What are named superior, middle, and inferior?
The cerebellum fine-tunes each of the eye movements so that they work together to bring and maintain images of objects in the interest of the fovea
What effect does the cerebellum have on the VOR?
Abnormal RAM
What is dysdiadochokinesia?
A swaying of the hips that counteract larger perturbations, basically moving our center of gravity around to keep it over our base of support
What is the hip balance strategy?
