Events in the gait cycle

Wikis > Biomechanics > Gait > Events in the gait cycle

Events in the gait cycle:
• Initial contact – first contact of the foot with the ground (usually heel contact)
• Forefoot contact – first contact of the forefoot with the ground
• Foot flat – the time at which both the heel and forefoot are both in contact with ground
• Heel off – the time at which the heel first leaves the ground
• Toe off – the final contact of the foot with the ground

Phases in the gait cycle:
• Stance phase – time between initial contact and toe off
• Swing phase – time between toe off and initial contact
• Single support phase – phase during which only one foot is in contact with the ground
• Double support phase – phase during which both feet are in contact with the ground
• Initial double support or loading phase – phase from initial contact on the ipsilateral limb to toe off on the contralateral limb
• Terminal double support or push off phase – phase from initial contact on the contralateral limb to toes off on the ipsilateral limb
• Flight or non-support phase – phase of non-contact during running
• Weight acceptance – phase from initial contact to maximum knee flexion on the stance limb
• Midstance – phase between weight acceptance and push off
• Push off – phase in late stance during which the ankle plantarflexes
• Lift off – early phase of swing between toe off and midswing
• Reach – late swing phase between midswing and initial contact

Temporal parameters of gait:
• Cadence – number of steps per unit time (eg steps per minute)
• Stride time or duration – time for one complete stride
• Step time or duration – time for one complete step
• Stride frequency – number of strides per unit time (eg strides per minute)
• Walking speed- speed= distance/time

Spatial parameters of gait:
• Step length – distance between successive foot placements
• Stride length – distance travelled in one complete stride
