4. GAIT CYCLE
Period of time from one heel strike
to the next heel strike of the same
limb
Phases:
consist of two phases
• Stance phase
• Swing phase
5. NORMAL GAIT
Series of rhythmical, alternating movements of the
trunk and limbs which results in the forward
progression of the center of gravity
7. CAUSES OF ABNORMAL GAIT
Caused by weakness
Caused by abnormal joint
position or range of
motion
Caused by muscle
contracture
Caused by pain
8. ABNORMAL GAIT
Due to pain
Following are the types of gait due to pain
1. Antalgic gait (Painful hip)
2. Gonalgic gait (Painful knee)
3. Podalgic gait (painful foot)
9. ANTALGIC GAIT
This is a compensatory gait pattern
adopted in order to remove or diminish
the discomfort caused by pain in the
Lower Limb or pelvis.
A patient with antalgic gait does not want
to spend time on the one leg due to the
pain.
Due to pain anywhere from foot to hip,
the patient avoids bearing weight on the
affected side
10. BIOMECHANICAL EFFECTS
With antalgic gait, there is an abnormal shortened stance phase on one
steps.
A patient wants to get their weight off of the affected extremity
The patient spends most of their stance of their time with their weight
being placed onto the normal leg.
The swing phase is enhanced on the affected side and may be shortened
on the normal leg in order to get the normal leg back to the ground.
This is done in order to lift the painful extremity off of the ground.
When pain is increased by walking, it leads to an antalgic gait.
11. CAUSES OF ANTALGIC GAIT
The etiology of antalgic gait can be divided into traumatic and non-
traumatic categories.
Traumatic etiologies are typically contusions, strains, and overuse
injuries
while non-traumatic etiologies include infectious, oncologic, and
bone processes.
12. MUSCLES AND ANGLE INVOLVED
Muscles
It most often affects the foot, knee,or hip.
Angle Effected
Normal: Stance phase:60%
Swing phase:40%
Affected: Stance phase:40%
Swing phase:60%
13. TREATMENT
The pain can be helped by
using a cane on the opposite
side of the painful extremity.
14. PSOATIC GAIT
Psoas bursa may be inflamed & edematous,
which cause limitation of movement due to
pain & produce a atypical gait.
Hip externally rotated
Hip adducted
Knee in slight flexion
The limp may be accompanied by
exaggerated trunk and pelvic movement.
16. DIPLEGIC GAIT
Patients have involvement on both
sides with spasticity in lower
extremities worse than upper
extremities.
Biomechanical effect
The patient walks with an
abnormally narrow base, dragging
both legs and scraping the toes.
17. MUSCLES INVOLVED
This gait is seen in bilateral
periventricular lesions, such as
those seen in cerebral palsy.
Extreme tightness of hip adductors
which can cause legs to cross the
midline referred to as a scissors
gait.
Muscles of the lower extremities
of the human body, usually those of
the legs, hips and pelvis
18. CAUSES OF DIPLEGIC GAIT
The exact cause is often unknown.
However, Spastic diplegia cerebral palsy has been associated with
genetic abnormalities;
congenital brain malformations;
maternal infections or fevers; and/or injury before,during or
shortly after birth.”
19. PATTERN
Flexion at hip
Flexion at knee
Ankles are extended and
internal rotated
Abduction at knee
20. EXAMPLES OF DIPLEGIC GAIT
Common abnormal gait patterns in
individuals with spastic diplegia
include:
Scissor gait (walking with the knees
turned inwards)
Tiptoeing (walking on the toes)
Crouch gait (walking with
continuously bent knees, hips, and
ankles)
