Validation of Two Acitivity Monitors in Three Inpatient Populations.

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to investigate the validity of Sens Motion and ActivPAL acitivity monitors. Thirthy-six patients from three different patient populations will be included: 12 acute high-risk abdominal surgery patients (+18 years), 12 hip fracture patients (+65) and 12 older medical patients (+65). Each patient will be asked to wear two sets of activity monitors while performing a predefined researcher-supervised protocol consisting of a range of positions and activities including lying down, sitting, standing and walking. Observations measured by time in each position will be used as a golden standard for physical activity and thus compared with the data produced by the acitivity monitors.

Detailed Description
-----------------
The study will investigate the association between activity measured by Sens Motion and ActivPAL acitivity monitors, respectively, and direct observation in order to investigate to which degree the two types of activity monitors are able to classify activity (i.e. lying, sitting, standing, walking, up/down transitions and steps). Thirty-six patients from three different patient populations will be included: 12 acute high-risk abdominal surgery patients (+18 years), 12 hip fracture patients (+65) and 12 older medical patients (+65). Inclusion criteria to be fullfilled: 1) admission from own home. Patients will be excluded for the following reasons: inability to walk independently with or without a walking aid; inability to transfer from lying to sitting, inability to transfer from sitting to standing, inability to cooperate, and inability to speak or understand Danish. Each patient will be asked to wear two sets of activity monitors (on the right thigh and on the chest) while performing a predefined, supervised protocol consisting of a range of positions and activities including lying down, sitting, standing and walking.
