Biomechancs of gait 2

Subject walks 150step per minute if step length 80 cm ,speed =

• 1200cm/hour

• 120m/s

• 90m/min

• 2m/s

During one gait cycle,each extremity passes through

• Five sub phases

• 3phases

• 2 double limb stance

• Non of above

Distance variable include all of the following except

• Step Angle

• Cadence

• Step length

• Stride length

Function of contralateral limb during single limb stance

• Propulsion

• Supporting

• Create new step

• Weight bearing

If GC time 5s stride time will be

• 5

• 10

• 3

• 2.5

Stance phase represent % GC

• 70

• 60

• 10

• 40

COP is during ipsilateral swing

• Between first and second toe

• Cross mid line of ipsilateral limb

• In between two feet

• In contralateral foot

Iliofemoral ligament contract affected of LOG on joint

• Ankle

• Knee

• Hip

• Cervical

Kinetic analysis includes

• Temporal variables

• Internal and external force

• Hip joint analysis from sagittal plane

• Distance variable

Third determinantof gait is

• Pelvic rotation in transverse plane

• Knee, ankle, foot,interaction

• Knee flexion in stance phase

• Physiological valgas
