In vivo biomechanical properties of plantar soft tissues have been assessed via manual indentation using simplified loading profiles , or in gait, with low image resolution/capture rates . Since plantar soft tissue properties are highly rate dependent  these methods are potentially inadequate. The Soft Tissue Response Imaging Device (STRIDE) permits functionally relevant loading profiles to be applied to the plantar tissues.
Materials and methods
STRIDE replicated the rapid loading experienced by the heel during gait. The ultrasound, load cell and LVDT measured the tissue response to compression. To achieve target strains improved bracing and multiple compressions are required.
This research was financially supported by SSL International Ltd. Thanks to Paul Busby, University of Salford, for development support for the STRIDE device. Thanks to Annamaria Guiotto, University of Padova, for support with protocol development and testing. Thanks to PhD candidate Hannah Jarvis for supplying the motion data used to derive input profiles to the STRIDE device.
