Beyond Performance Status: Electronic Activity Monitoring to Assess Functional Activity of Patients With Gastrointestinal Malignancy During Chemotherapy.

All registered patients will receive a wearable EAM device that will measure their physical activity. Patients will wear this device around their wrist for the designated period of assessment. The EAM device has the potential to measure active minutes, number of steps, distance walked and number of floors climbed. For the purpose of this study the EAM data captured will focus on daily step count.

Participants will be asked to complete this self-administered, paper-based questionnaire each day that they are expected to wear the EAM device. The questionnaire was designed specifically for the purpose of this study. It consists of 5 items that ask about the patient's perceived level of physical activity and fatigue in each 24 hour period that they have worn the EAM device. The daily questionnaires will be optional; however each participant will be encouraged to complete them.
