This chapter will explore more on the design procedure of a prosthetic leg and the calculations that come into play in this procedure. The design will be based on the parameters and function of a normal leg and also on the current available prosthetic legs. In prosthetic leg calculations‚ the main factors to consider are the kinematics‚ kinetics and the energetics. Kinetic quantities are computed by first measuring the external forces acting on the body. For normal walking‚ the external forces are

Intense knee pain is usually the presenting symptom that occurs during activities such as running‚ jumping‚ squatting‚ and especially ascending or descending stairs and during kneeling. The pain is worse with acute knee impact. The pain can be reproduced by extending the knee against resistance‚ stressing the quadriceps‚ or striking

CHAPTER 3: THE MUSCULAR SYSTEM Three Types of Muscle * Muscle tissue is a collection of cells that shorten during contraction which create tension that results in movement * Tendons are touch bands of connective tissue that join muscle with bones Skeletal muscles * Muscles that are attached to bone (by tendons and other tissue) * Comprise 30 to 40% of human body weight * Humans have conscious control (conscious muscle) over these muscles (the brain can tell them what to do)
