Capturing objective data of the postoperative changes in the mobility of
patients is expected to generate a better understanding of the effect
of postoperative treatment. Until recently, the collection of
gait-related data was limited to controlled clinical environments. The
emergence of accurate wearable accelerometers with sufficient runtime,
however, enables the long-term measurement and extraction of mobility
parameters, such as “real-world walking speed”. An interim analysis of
1967 hours of actibelt data (3D accelerometer, 100 Hz) from 5 patients
(planned total 20) with a femur fracture and 5 patients (planned total
20) with a humerus fracture from a geriatric population at two different
sites of the university hospital of the Ludwigs-Maximilian-University
in Munich was performed. Mobility data was captured during several days
of stationary treatment starting directly after surgery and during a
short follow-up visit six weeks after the surgery. Preliminary results
show an increase of the mean walking speed between the two visits
independent of the type of fracture. Patients with a humerus fracture
tended to walk faster than patients with a femur fracture during both
visits. The data also reveals an unexpected low level of mobility during
the stationary stay. Mobile accelerometry can be used to evaluate
different postoperative mobilisation strategies and even provide
near-time feedback in geriatric trauma patients.
