Relationship between normalized stride length and cadence in HS and PD.
<p>(A) Relationship between normalized stride length and cadence during linear (LIN) trajectory in HS (blue dots) and PD (green dots). (B) Relationship between normalized stride length and cadence during curved (CUR) trajectory in HS (violet dots) and PD (bordeaux dots).</p
Relationship between gait variables during linear and curved trajectories in HS and PD.
<p>(A) Relationship between normalized stride length during linear (LIN) and curved (CUR) trajectories in HS (blue dots) and PD (orange dots). The slopes of the best fit line across each group are similar but HS have a longer stride length in relation to cadence during CUR. (B) Relationship between cadence during linear (LIN) and curved (CUR) trajectories in HS (violet dots) and PD (sky-blue dots). The slopes of the best fit line across each group are similar.</p

Mean double support phase in % of gait cycle (GC) of Parkinson’s Disease patients (PD) in turning toward the less and the more affected side and correlation between asymmetry score and mean double support phase.
<p>(A) Mean double support phase in %GC of PD turning toward the less (blue column) and the more (red column) affected side. (B) Relationship between asymmetry score, computed from UPDRS, and mean double support phase in PD turning toward the less (blue dots) and the more (red dots) affected side. The slope of the best fit lines across each group are similar.</p

Mean speed of Parkinson’s Disease patients (PD) in turning toward the less and the more affected side and correlation between asymmetry score and mean speed.
<p>(A) Mean speed of Parkinson’s Disease patients (PD) in turning toward the less (blue column) and the more (red column) affected side. (B) Relationship between asymmetry score, computed from UPDRS, and mean speed used by PD for turning toward the less (blue dots) and the more (red dots) affected side. The slope of the best fit lines across each group are similar.</p
Coefficient of variability (CV) of temporal gait variables during linear (LIN) and curved walking in PD and HS.
<p>During curved walking the foot inside (IN) and outside (OUT) the trajectory is considered separately. *, P<0.05 **; P<0.005. (A) CV of single support duration. (B) CV of double support duration. (C) CV of swing phase duration.</p
