It involves Evaluation, Treatment phase for arrest  of pathophysiologic process, Focussing phase on organ performance, Task reacquisition and  Environmental Modification

Eating, Grooming (e.g., brushing teeth, combing hair, shaving, applying makeup), bathing, dressing, and personal hygeine(e.g., toileting). Bathing and dressing can be divided into upper body and lower-body management.

Any restriction or lack resulting from impairment, of ability to perform an activity in the manner or within the range considered normal for a human being.e.g., difficulty in walking after lower limb amputation.

It is a psychiatric disability, which can be defined as deficits in cognitive, emotional and psychomotor skills, which impairs social and occupational functioning.

Tardive Dyskinesia is a syndrome of abnormal involuntary movements which develop in people taking dopamine receptor blocking drugs.

AGONIST-Prime mover which can cause a specifif joint motion.For eg., the biceps brachii contracts to cause elbow flexion
ANTAGONIST -Any muscle that can produce a motion oppoosite to the specific agonist motion.For eg., triceps brachii is an antagonist to elbow flexion.
SYNERGIST -These muscles  normally contract to remove unwanted actions of agonists or to stabilize other (usually more proximal) joints. For eg., during elbow flexion by the biceps brachii, the forearm pronators contract to remove the undesirable supination which the biceps would produce.

This is a syndrome,usually caused by an extra cervical rib that compresses the medial cord of  the brachial plexus and the axillary artery, results in tingling and numbness in the medial aspect of the arm, along  with decreased upper extremity pulses.

Femoral nerve(L2-4)- Knee extension, hip flexion and knee jerk
Obturator nerve(L2-4)-Hip adduction 
Sciatic nerve (L4-S3)-Knee flexion plus other functions along its branches , the tibial and common peroneal nerves
Tibial nerve(L4-S3)-Foot inversion, ankle plantar flexion and ankle jerk
Common peroneal nerve(L4-S2)-Foot eversion, ankle and toes dorsiflexion

Control of voluntary movement on the opposite of the body,Broca's area responsible for speech, control of complex behavioural and executive activities.

Audition,ability to read and write.
