Clinical Validation of a Mobility Monitor to Measure and Predict Health Outcomes

The study plans to include patients in two groups, both acute (during hospital stay after hip fracture) and subacute (up to 6 months post hip fracture from waiting lists). With this strategy, it is possible to have the life-course of PFF (first 12 months and the time after). Acute phase inclusion is defined as inclusion start on first days after surgery and will be completed within the first 14 days. Subacute phase inclusion is defined as inclusion from waiting lists, where baseline will be conducted up to 6 months after hip fracture surgery. Fear of falling will be tested using a single question during the acute phase and the short form of the fall efficacy scale international (Short FES-I) for all other assessments. For the acute recruited group of patients (2/3 of included participants), sensor recordings will be made on patients from hospital stay (attached on day 2 after surgery) and continue after discharge (until day 9 depending on battery capacity of the sensors) to be able to monitor and describe DMOs from about 2 days during hospital stay and several days after discharge to be able to evaluate improvement during the acute rehabilitation process. For all other assessments, sensor recordings will be collected for a minimum of 7 full continuous days in line with the core data collection manual. Hip fracture patients will be tested for sarcopenia according to the updated definitions of the European and US-American working groups. In centers where bioimpedance measurements are possible, participants will receive this measurement as part of the core data collection.
