If you work with runners, surface is part of the assessment. In this study, Kurt Schutte, PhD et al. tested 28 runners across three outdoor surfaces: concrete road, synthetic track and woodchip trail. Using trunk accelerometry, they found that the woodchip trail affected dynamic stability, dynamic loading and step frequency compared with concrete. In other words, the surface changed how runners stabilized, loaded and organized their stride. For physios, that matters because the runner (and their injury!) you see on a treadmill is not always the same runner you see outside. A runner who looks stable in the clinic may respond differently on a trail, track or road, especially when surface stiffness, evenness and familiarity change. That does not mean one surface is good and another is bad. It means surface should be part of the conversation when symptoms appear in specific environments, when return-to-run decisions are made, or when the runner reports that “it only happens outside.” Outdoor running analysis helps bring that context into the assessment. It gives physios a way to look at how stability and loading behave closer to the environment where the runner actually trains. Comment “SURFACE” and we’ll send you the paper.
