AIM
To understand functioning and usage of electromechanical units which will restore normal functional ability of particular organ which is defective temporarily or permanently.

OBJECTIVES
• To study various mechanical techniques that will help failing heart.
• To study the functioning of the unit which does the clearance of urea from
the blood.
• To understand the tests to assess the hearing loss and development of electronic devices to compensate for the loss.
• To study the various orthodic devices and prosthetic devices to overcome orthopaedic problems.
• To understand electrical stimulation techniques used in clinical applications.
