Visualizations of rotational curves within a Standardized Gait Cycle

This dataset contains graphs and a movie. Both show visualizations of rotational curves in the transversal plane within a Standardized Gait Cycle from Vertebra prominens downwards, ending at the pelvis. They display 201 anonymous healthy people aged 18-70 years walking at 2,3,4, and 5 km/h on a treadmill. They are based on a SPSS (v23) syntax file and a relating graph template that can be found at our datasets as well. Files are numbered subsequently across all speeds and can be linked by number to its non-standardized counterpart in a further dataset.
Positive values show vertebral body rotation to the left, negative values show rotation to the right. Percent of the Standardized Gait Cycle (0-100%) is displayed on the abscissa, always starting with Initial Contact of the right foot. Within a Standardized Gait Cycle the duration of the stance phase right is expected to be 60% (Perry, 1992).
As can be seen in the graphs, interpolating spline functions work for average walking speed measurements leading to a more precise determination of relevant and characteristic points (e.g. maxima, phase shifts, lumbar and thoracic movement behavior), thereby aiding in in the clarification of individual features.
