Cerebellar Disorders
Definition
The cerebellum is a structure present in the brain meant for the commencement of smooth integrated and coordinated movements. It is required for movements that need the intensive, synergistic contractions of multiple groups of muscle. It also permits those movements to be performed with efficiency and accuracy.
Cerebellar disorders are the disorders of cerebellum that occurs due to lesions at any level or part of the cerebellum. The most obvious and most common consequence of cerebellar disorder is uncoordinated or clumsy movements and this condition is referred as ataxia.
Cerebellum performs following three functions:
 Coordination of Movement (controls the timing and pattern of muscle activation during movement) …show more content…
There are two distinguishable mechanisms of cerebellar disorders midline and hemispheric.
Midline cerebellar disorders are related to lesions of the vermis and considered by imbalance (ataxia). Severe midline disorders unable person to sit on their bed without maintaining balance (truncal ataxia). Midline cerebellar disorders frequently affect eye movements; there might be nystagmus, ocular dysmetria and poor vision. Lesions of the floccolonodular lobes of cerebellum cause disequilibrium and vertigo.
Hemispheric cerebellar disorders are described by incoordination of the limbs. There may be disintegration of movement, dysmetria and rebound. Dysdiadochokinesia is another disorder of cerebellar hemisphere lesions presenting with the asymmetrical act of rapid alternating movements. Tremors (intention tremors and kinetic tremors) are another pathology related to hemispheric lesions. Intention tremors may be present on an attempt to touch an object.

The physical therapy interventions established in existing literatures consist of balance training, gait training and coordination exercises like strengthening, orthostatic vibration, and the application of Transcranial magnetic stimulation (TMS) has been suggested.
The objective of physical therapy for cerebellar disorders is to improve the ability to stabilize body with the purpose of standing, walking and functioning autonomously for as long as possible. Physical therapist will conduct a comprehensive evaluation that will help identify the precise areas of imbalance and incoordination problems with the intention to devise a suitable treatment plan for the patient.
Some exercises targets receptors in joints that convey brain where the body parts are, a sense recognized as proprioception. Certain techniques of stretching, resistance exercises and walking on various forms of surfaces are used for this
