Currently, a study is being conducted at the University of Washington in
the Department of Environmental and Occupational Health Sciences
assessing muscle fatigue associated with computer use by using
electrical stimulation. We would like to invite you to participate in
the study. The study is expected to last about 1-2 hours on the
orientation day and 8 hours for the following four days. If you do
decide to participate, you will be compensated $15/hr for your time.
During this study, we will attach surface electrodes to your forearm. On
the orientation day, we will introduce you to the electrical stimulation
methods and the overall protocols. On the control day, you will be asked
to rest for the whole eight hours. On each day of the four experimental
days, you will be asked to perform four 75-min specific tasks using a
keyboard and mouse with three breaks: a 15-min morning and afternoon
break, and 30-min lunch break, respectively. Between the tasks,
electrical simulation and questionnaires will be use to assess your
muscle fatigue. The electrical stimulation may cause discomfort, similar
