Exercise adherence

​Research strategy for “Technology to measure and improve exercise-therapy adherence – Copenhagen (TECHX-CPH)”

To investigate how various technologies can measure and improve adherence to home-based exercise in different patient populations, who are commonly prescribed home-based exercise after initial instructions.    

The experimental approach is a 3-phased model with initial phase-1 validation work in healthy subjects. The main findings from this phase have been: development and validation of gold-standard sensor technology to measure adherence and quality of home-based, elastic band exercise (Rathleff et al 2014; Rathleff et al 2013; Rathleff et al 2015), and validation of second generation, commercially available, sensor technology (McGirr et al 2015; Faber et al 2015). Some phase-1 validation work is still ongoing.

Currently, the strategy has a strong focus on feasibility assessment in different patient populations, that is, does the technology actually work as intended when used in a clinical setting (see for example, Rathleff et al 2016). This second phase is a pre-requisite for the following third phase of large-scale randomized controlled trials, using the technology to objectively quantify and improve adherence to home-based exercise in different patient populations, who are commonly prescribed home-based exercise after initial instructions.

TECHX-CPH Collaborators
The basis for the research strategy is a strong collaboration between PMR-C and the Research Unit for General Practice in Aalborg, Aalborg University, Denmark (Dr. Michael Rathleff). In addition, the strategy involves ongoing collaboration with other frontline research groups and programs, including: The Mærsk Mc-Kinney Møller Institute, University of Southern Denmark, Odense, Denmark, The Lundbeck Foundation Centre for Fast-Track Hip and Knee Replacements, Copenhagen, Denmark, Clinical Orthopedic Research Hvidovre, Copenhagen (CORH), Section of Surgical Pathophysiology, Rigshospitalet, Copenhagen, Research Unit, Center for Elective Surgery, Silkeborg, Denmark, and the municipalities Hvidovre, Brøndby, and Copenhagen.
