- Gait cycle
- Stance phase (60%)
- Heel strike : initial contact
 - Load response : foot flat
 - Mid-stance : push off, Hip and knee go into extension
 - Terminal stance : Heel off, hip, knee and anke flex
 - Pre-swing : toe-off, the begining of the swing phase
 
 - Swing phase(40%) the foot does not have any contact with the ground
- initial swing : hip and knee flex, ankle dorsiflexion
 - mid swing : hip and knee still flex, ankle dorsiflexion
 - terminal swing : hip flex and knee maximum extension, ankle dorsiflexion

 - Stance phase (60%)
 
- Abnormal gait  
- Antalgic gait 
- Painful gait, self protective gait
 - The stance phase on the affected leg is shorter than that on the unaffected leg

 - Ataxic gait
- Cause : Injury to the cerebellum, Sensory deficits in lower limb
 - poor sensation or lacks muscle coordination
 - The patient watches the feet while walking

 - Gluteus Maximus(Lurch) gait
- Cause : weaken gluteus maximus muscle(primary hip extensor)
 - Trunk moves backward while walking

 - Gluteus medius(Trendelenburg) gait
- Cause : hip abductor muscles(gluteus medius, gluteus minius)are weakend
 - The pelvic drops oppsit side(unaffected side is dropped), trunk goes laterally to other side(affected side) to keep balace while walking

 - Hemiplegic gait 
- referred to as neurogenic gait or flaccid gait
 - Cause : lesion in the central nervous system
 - Swings the paraplegic leg outward and ahead in a circle
 - One side paralyzed
 - Assessment – Gait – Hemiplegic Gait Demonstration – YouTube
 
 - Diplegic gait
- Both side paralyzed
 
 - Parkisonian gait
- The gait is characterized by shuffling or short rapid steps at times
 - During the gait, the patient may lean forward and walk progressively faster as through unable to stop

 - Quadricep gait
- Cause : injured quadricep
 - Weak Quadriceps Gait (FGCU) – YouTube
 
 - Sissors gait 
- Neurologenic or spastic gait
 - Cause : result of spastic paralysis of the hip adductor muscles
 - Scissors gait – YouTube
 
 - Drop foot or steppage gait or slap gait
- Cause : weak or paralyzed dorsiflexor muscles
 - Patient lifts the knee higher than normal to avoid dragging the foot.
 - can hear “slap”

 - Choreiform(Hyperkinetic) gait
 
 - Antalgic gait
