Background: Physical activity in palliative care patients is closely linked to independence, function, carer burden, prognosis, and quality of life. Changes in physical activity can also be related to service provision needs, including requirements for support and prognosis. However, the objective measurement of physical activity is challenging, with options, including self-report, invasive and intensive measures such as calorimetry, or newer options such as pedometers and accelerometers. This latter option is also becoming more viable with the advent of consumer technology driven by the health and exercise industry. Objective: In this article, we highlight our experiences of activity monitoring in palliative care patients as part of telehealth trial. We also highlight the strengths and limitations of activity monitoring in the palliative care population and potential applications. Conclusions: Although the advent of consumer technology for activity measurement makes their use seem attractive in clinical settings for palliative care patients, there are a number of issues that must be considered, in particular the reason for the activity monitoring and associated limitations in the technology.
