“…7 With this methodology, accuracy for walking-and-resting-bout detection was 97.1%, and the estimation of walking distance was highly accurate (rϭ1 between actual and processed distance). 7 Reproducibility of the GPS-measured walking distances was tested among 7 healthy subjects on test-retest prescribed walking protocols. The Pearson correlation coefficient and the coefficient of variation between tests 1 and 2 were 0.997 and 4.1%, respectively (A.L.F., P.A., and B.N.-D., unpublished data, 2007).…”

“…A simple spreadsheet analysis with an Excel file can help to retrieve information on walking-or-stopping bouts and estimate the walking distance between 2 stops in normal subjects. 7 Nevertheless, the ability of GPS recordings to assess the walking ability of patients with claudication has never been tested. We aimed to compare the results obtained with various nontreadmill methods, specifically the GPS technique, with the MWD observed in the laboratory on a treadmill.…”

“…Raw data were downloaded from the GPS receiver after each experiment and converted to indicate speed and distance with Mapsource software (version 6, Garmin Ltd), and data analysis was performed on a personal computer with a spreadsheet (Microsoft Excel 2000, Microsoft Corp, Redmond, Wash) as described previously. 7 …”

“…7 Thus, as in our previous experiments, a manual postprocessing analysis was performed on all bouts that lasted from 6 to 15 seconds. This postprocessing analysis was facilitated by the use of the map projection of the patient's position during the tests (CartoExploreur, version 3.11.0, build 2.6.6.22, Bayo Ltd, Appoigny, France).…”

“…Correlation with actual distance and walking speed was 1.00 and 0.95, respectively, during predefined walking protocols in normal subjects. 7 To the best of our knowledge, this is the first study to use a GPS to assess free-living outdoor walking capacity by measuring MWD during a period of unconstrained outdoor walking. The correlation with MWD TT that we observed was the highest among other usual measurements of walking capacity.…”

Background-The maximal walking distance (MWD) performed on a treadmill test remains the "gold standard" in estimating the walking capacity of patients who have peripheral arterial disease with intermittent claudication, although treadmills are not accessible to most physicians. We hypothesized that global positioning system (GPS) recordings could monitor community-based outdoor walking and provide valid information on walking capacity in patients with peripheral arterial disease. Methods and Results-We studied 24 patients (6 women

A new possibility to assess the perioperative walking capacity using a global positioning system in neurosurgical spine patients: a feasibility study

et al. 2015

In this feasibility study, we demonstrated that this tool is able to measure the perioperative mobility and walking-capability. The certainty of data is dependent on the patients' compliance. The measuring method is used as a low cost, easily accessible, and easy-to-use technique, which seems to be superior to common methods like a treadmill-tests or walking tests. Nevertheless, these results are still to prove in upcoming analysis.

Tracking the movements of homeless populations presents methodological difficulties, but understanding their movements in space and time is needed to inform optimal placement of services. This pilot study developed, tested, and refined methods to apply global positioning systems (GPS) technology paired with individual narratives to chronicle the movements of homeless populations. Detail of methods development and difficulties encountered and addressed, and geospatial findings are provided. A pilot sample of 29 adults was recruited from a low-demand homeless shelter in the downtown area of Fort Worth, Texas. Pre- and post-deployment interviews provided participant characteristics and planned and retrospectively-reported travels. Only one of the first eight deployments returned with sufficient usable data. Ultimately 19 participants returned the GPS device with >20 h of usable data. Protocol adjustments addressing methodological difficulties achieved 81 % of subsequent participants returning with sufficient usable data. This study established methods and demonstrated feasibility for tracking homeless population travels.

Study of Human Outdoor Walking with a Low-Cost GPS and Simple Spreadsheet Analysis

Abstract: Low-cost, commercially available GPS may be accurate in studying outdoor walking, provided that simple data processing is applied. Future validation in diseased subjects could allow for the study of free-living walking capacity, such as maximal walking distance in vascular patients.
