Study on Design and Performance Specifications of the Prosthetic Hands Mohd Azeem and Aasiya Parveen 1 Introduction World Health Organization (WHO) estimates that around 650 million individuals suffering from disability worldwide and 80% of those 650 million individuals are in developing countries [1]. The number of upper limb amputees is approximately 2.4 million [2]. Rehabilitation devices for overcoming disability are so rare and expensive that just 3% of the amputees in the developing countries can afford them [1]. To address this problem and to make prosthesis readily available to the user, extensive research is being done. In the course of the most recent couple of decades, there have been extraordinary steps in the improvement of novel prosthetic hands and terminal devices that exploit the most recent mechanical advances, moving toward more dexterous, practical hand devices [3]. Nonetheless, there is as yet an incredible hole between the present status of the arts and devices that have the ideal mix of being exceptionally useful, tough, corrective, and cheap. In this paper, we survey the plan details of a wide scope of commercial pros- thetic terminal devices and exploration hands, focusing primarily on anthropo- morphism in such devices. The physical performance specifications as well as any justification provided by the developer regarding the scientific validity of design parameters are discussed. Various surveys are taken into account to corroborate various claims or comment stated in this paper. M. Azeem Department of Mechanical Engineering, Jamia Millia Islamia, New Delhi, India A.
