functions of cerebellar function

1. Cerebellar function Prepared by CHINMAYEE SAHU Assistant professor

2. Cerebellar dysfunction can cause incoordination that can affect coordination that may affect any body region and cause a variety of clinical symptoms. Cerebellum responsible for muscle control, including balance and movement

3. Intention tremor is the rhythmic oscillating movement that develops during precise intentional movements due to involuntary alternating contractions of opposing muscles .

4. Dysmetria is an inability to estimate the ROM necessary to reach the target of movement . Two types of dysmetria are known . Hypermetria involves the limb overshooting the target. Conversely , hypometria involves the limb undershooting the target.

5. Dyssynergia is a “decomposition of movement” in which voluntary movements are broken up into their component parts and appear jerky. Dyssynergia can also cause problems in articulation and phonation.

6. Dysdiadochokinesia is impairment in the ability to perform repeated alternating movements, such as pronation and supination, rapidly and smoothly. • Adiadochokinesia is the loss of ability to perform rapid alternating movements

7. • Ataxia is unsteadiness, incoordination, or clumsiness of movement. • Ataxic gait is a wide-based, unsteady, staggering gait with a tendency to veer from side to side

8. Rebound Phenomenon of Holmes The rebound phenomenon of Holmes is the lack of a check reflex, that is, the inability to stop a motion quickly to avoid striking something.

9. Nystagmus Nystagmus is an involuntary movement of the eyeballs in an up-and-down, back-and-forth, or rotating direction . It interferes with head control and fine adjustments required for balance . Nystagmus can occur as a result of vestibular system, brainstem, or cerebellar lesions .

10. Dysarthria Dysarthria is explosive or slurred speech caused by incoordination of the speech mechanism . The client’s speech may also vary in pitch or may seem nasal and tremulous, or both.
