Figure 3. Kinematic Variability (MeanSDpos and MeanSDvel) of C7.
A: Mean standard deviation (MeanSD) of C7 vertebra marker displacements (position). B: MeanSD of C7 vertebra marker velocity. Each graph shows data separately for all healthy controls (AB) and all amputees (TTA) for all three walking conditions. Error bars indicate the appropriate between-subject ± standard error.
