TODO - Sit-to-Walk (STW) is a critical task for daily independence, yet its two inherent destabilizing events (seat-off, walking initiation) may diminish postural stability  under fast motion speed (FS). This study aimed at the FS effect on the STW spatial  and temporal patterns, with a specific interest in the relative STW temporal  pattern. The STW kinetics and kinematics were recorded (n=18 men, 20.7±2.0 years) at  preferred and FS. Statistics included One-Way repeated measures ANOVA (SPSS 25.0,  p≤0.05). The FS spatial pattern reveals a discontinuous mode of the forward ground  reaction force, indicating a balance rather than a propulsive strategy during the  Rising phase. The FS relative temporal pattern reveals the prolongation of the  Leaning phase (most possibly due to the feet repositioning), the shortening of the  Rising and the Walking phases, and a relative delay in the spatial variables  (p≤0.05). Overall, the results do not allow the STW consideration at FS as a  "magnified" with respect to force, or a "shrinked-in" with respect to time, copy of  the preferred motion speed. As more generic and versatile than the absolute one, the  relative temporal pattern may be used as a reference for a variety of populations.
