Can inertial movement sensors (IMUs) provide a valid and reliable way of measuring Spinal Mobility in Axial Spondylo-arthritis (axSpa)? A clinimetric evaluation

Objectives

The main objective of this project is to test the reliability of electronic sensors in measuring spinal movement. Current methods rely on tape measures and are not reliable enough to evaluate new treatments for axSpa. We also want to test if we can reliably measure spinal movement when the patient is unsupervised.

To date have completed three validation studies – a reliability study, a criterion validity study comparing sensor accuracy to the UCOTrack© gait lab system, and an exploratory ambulatory study. In the next phase we will measure the responsiveness of our instrumented metrology index. We are also developing a smartphone app to allow patients to obtain feedback on their spinal mobility from wearable sensors.

Patient voice

An oral communication about measuring in axSpA has been presented at the VI National Congress of Chronic Patients (Spain). Patients in Londonderry have attended a workshop to discuss the project and the design process for a smartphone application.

Interim results

The project started in April 2017. Interim results on IMU sensor accuracy & reliability in axSpA patients will be presented in June 2019.
