"What we can or cannot do, what we consider possible or impossible, is rarely a function of our true capability. It is more likely a function of our beliefs about who we are."

CLINICAL SCENARIO
Juan, a college student, has been working part time in the university library to help pay for his education. He works 20 hours a week, inputting information on a computer for the electronic library. Over the past two weeks, he has been spending a lot of extra hours on his own computer, completing three major reports that are soon due for two courses he is taking this semester. He has noticed that his wrist has recently started hurting after about 30 minutes at the computer. His neck also aches by the end of the day. He cannot afford to either cut back on his work hours or stop doing his homework. He thinks he is doing something wrong either at work or at home but he is not sure. He just knows that he has to fix the problem, whatever it is, before it gets worse.

This chapter will describe the kinematics of everyday functional activities. It is provided to guide you in thinking through a kinematic analysis, using and applying your newly acquired kinesiology knowledge to analyze common movements. This chapter does not intend to give you an exhaustive list of the many different daily activities in which all of us engage, but rather offers a few examples to illustrate the process involved in a kinesiological analysis of common activities. By reading through and studying the examples illustrated, you will gain insight into the joint motions and muscle activity requirements needed to produce a movement safely and successfully. Once you develop these skills, you should be able to generalize this skill to any and all activities that you will encounter within your own daily life and to those of the individuals that you will work with in the clinical arena.

Each of these skill analyses will break down the activity into three elements. ...
