Abstract:
Sensor-based monitoring allows continuous observations of patient mobilization after proximal femoral fractures. A wrist-worn motion tracker allows long-term observation that is low in interruption and constraints for subjects. Objective Description of steps development after hip fracture surgery on a specialized geriatric trauma ward and beyond. Material and methods In the explorative long-term field research study, an applicable motion tracker observed steps per day of 20 patients (80% female, mean age 85.2 years ± 7.86 years) for 10 weeks. Weekly mean values (days 1–7, 8–14 etc.) of steps per day formed the database for descriptive analysis (mean, SD, min, max, median). Results During observation weeks (ow) a positive development of steps took place. A mean increase factor of 1.285 (±0.351) occurred from ow 1 ( M = 353.57 ± 310.15) to ow 10 ( M = 2482.07 ± 1374.12). The highest increase by a factor of 1.8 could be reported from ow 2 ( M = 556.27 ± 478.11) to ow 3 ( M = 1024.86 ± 921.24) as well as from ow 6 ( M = 1268.21 ± 880.47) to 7 ( M = 2367.14 ± 1680.08). A slight decrease of steps occurred from ow 4 ( M = 1208.27 ± 1210.45) to ow 5 (0.99-fold) and from ow 9 ( M = 2689.98 ± 2339.71) to 10 (0.92-fold). High ranges and standard deviations in relation to the mean occurred constantly. The presence of several step development groups could be presumed. Conclusion Motion tracker and the variable steps per day can represent the ability to walk within an everyday environment, with a possible underestimation of 〈 10%. Differences regarding observation lengths and disruptions occurred. Cluster analysis should detect group attributes of different courses of development in subsequent studies.
