Stride 1 of 25 What is the distance between 2 consecutive footfalls of the same foot? Stride length 2 of 25 What is the distance between two consecutive footfalls of alternate feet Step length 3 of 25 What is the lateral distance between medial borders of consecutive footprints? Base of gait 4 of 25 What is the cycle time? The stride time in seconds 5 of 25 What is the period in step when the foot is in contact with the ground? Stance phase 6 of 25 What is the period when the foot is not in contact with the ground? Swing phase 7 of 25 What is the period in step when neither foot is in contact with the ground? Flight phase 8 of 25 During what gaits is flight phase present? Running 9 of 25 What is the correct order? Heel strike, foot flat, mid stance, toe off 10 of 25 How can gait speed be calculated? Step length/step time 11 of 25 To move with minimum amount of energy expenditure is the goal of what gait? Walking 12 of 25 To move with minimum energy expenditure within a given time is aim of what gait? Running 13 of 25 Most movement during gait occurs in what plane? Sagittal 14 of 25 What is NOT a difference between walking and running gait? Running has an increased stance phase 15 of 25 What model describes walking gait?
