The goal of this research is to develop a normative database of upper extremity motions during several basic activities of daily living. The tasks they will complete include: 1) Wiping a plate with a dish towel, 2) applying deodorant to contralateral axilla, 3) grasping objects off of a high shelf, 4) turning a door knob, 5) grasping and lifting a laundry basket from the floor, 6) pouring water from a pitcher and drinking from a cup, 7) flipping pages from a newspaper, 8) cutting food with a knife, 9) picking up a phone and placing it to the ear, 10) placing pills in a pill box, 11) removing a pen cap and drawing a line, and  12) pushing a pin into bulletin board. Each participant will perform ten repetitions of each task.  The three-dimensional motion of reflective markers placed on the hand, lower arm, upper arm and trunk will be collected using a motion capture system.   We will determine the active range of motion of each of the joints, as well as movement time, smoothness, and synergy between the joints.  The results of this study will be used to help improve the design of upper extremity prosthetics and training protocols for people learning to use upper extremity prosthetics.  This will allow us to later compare the way healthy individuals move their arms to the way patients with arm prosthetics move in an effort to understand why prosthetics do not always meet the needs of patients.  It is our hope that these findings will help to design better prosthetics and improve the quality of life of patients with upper extremity amputations. We are currently recruiting healthy control subjects. Please contact the lab if interested in participating!
