Primary outcome measure
The primary outcome was ankle dorsiflexion in gait. Amplitude of ankle dorsiflexion during stance phase measured using the Cartesian Optoelectronic Dynamic Anthropometer (CODA) motion analysis (Charnwood Dynamics Ltd., Leicestershire, UK). Markers were placed on the lower leg in standardised positions [Position of the reflective markers on the lower leg. Reflective markers on the Derivation of embedded vector basis (EVBs) for each segmentThe change in the left and right ankles were analysed separately and were considered independent of each other, as supported by studies in healthy adults who show differences between sides during weight bearing ankle DF ROM measurements [A mean of five steps captured from an average of three walking trials were used for data analysis.
