21 Questions
What is the approximate percentage of the gait cycle that consists of the stance phase?
58-62%
What event marks the beginning and end of a gait cycle?
Heel contact of the support limb
What is the primary division of the gait cycle into two phases based on?
The limb in contact with the ground
What is the term for the point at which the center of pressure is directly beneath the supporting limb?
Midstance
What is the position of the ankle joint at the beginning of the midstance period?
10 degrees plantarflexed
What is the movement of the subtalar joint during the contact period of the stance phase?
Pronation
What is the sequence of events during the Stance Phase of the gait cycle?
Contact Period, Midstance Period, Propulsion Period
What is the movement of the pelvis and hip joint during the swing phase of the gait cycle?
External rotation
What is the position of the subtalar joint at the end of the midstance period?
Supinated
What is the moment that occurs at the transition from the Stance Phase to the Swing Phase?
Toe Off Moment
During the gait cycle, what joint is internally rotating and flexed at the beginning of contact?
Hip joint
What happens to the subtalar joint when the heel hits the ground?
It pronates
What is the movement of the tibia during the propulsion period?
It moves forward
What is the movement of the leg during the swing phase?
It externally rotates
What is the direction of the foot at heel contact?
Inverted
What is the implication of the foot being maximally pronated during the swing phase of the gait cycle?
The foot will have a propensity to develop shin splints.
What is the typical position of the calcaneus at heel contact?
Inverted
What is the significance of the heel remaining on the ground as the hallux of the swing leg passes the malleolus of the support leg during the gait cycle?
It indicates a normal heel off timing.
What is the significance of midtarsal stability during midstance?
It indicates a stable foot during midstance.
What is the significance of the center of pressure during the gait cycle?
It indicates the amount of force generated during the stance phase.
What is the consequence of extensor substitution during the swing phase of the gait cycle?
The foot will have an increased risk of developing shin splints.
Explore the different phases of the gait cycle, including stance and swing phases, and learn about the events that occur during each phase. Understand the roles of the ankle joint, hip, and pelvis in propulsion and movement.
