Abstract: Background: The subtalar joint allows complex motion of the foot relative to the leg, the analysis of which has presented a major challenge for researchers. The considerable inter-subject variation in structure and function of the subtalar joint highlights the importance of developing a technique to assess the movement in individuals rather than an overarching description of function. The use of skin mounted markers is therefore preferable, allowing the non-invasive collection of data. The aim of this study was to assess the face validity of a skin mounted marker based technique to measure the in vivo movement of the subtalar joint.
Methods: Thirty participants were recruited using minimal exclusion criteria. A previously tested skin mounted marker placement technique was used in conjunction with two CODA MPX30 sensors to capture data during walking. Data produced was compared to that of previous studies that used bone mounted markers.
Results:The results in all three planes represented feasible outcomes when compared to those of previous studies, the data falling within the ranges published. Patterns of movement demonstrated are similar to, although not the same as, those shown by previous investigations.
Conclusions: While this study did not produced patterns of movement that exactly matched those of previous investigations, nor did the previous investigations. The results of this study were within the ranges previously published and the patterns of movement shown were feasible. The results suggest that it is possible to use the methodology to assess the in vivo movement of the subtalar joint.
