When assessing posture laterally, the plumb line will coincide with the following landmarks:

Slightly Ant to Lat Malleolus
Slightly Ant to head of Fibula
Great Trochanter
External Meatus (ear)

In Coronal Plane


Antalgic Gait

The bodies attempt to protect itself from further injury (ankle leg, hip, low back)

Ex: linking because of ankle sprain

Stance phase is shorter on affected side as person attempts to remove weight from affected leg


Ataxic Gait

Poor sensation in Extremities
Loss of m'm coordination

Person keep feet fighter part for balance + may exaggerate all mvmts


Hemiplegic Gait

Swing affected leg into ABduction + FLX

Frequently the affected arm is held I shoulder ADDuction, elbow & wrist FLX & pronation of forearm


Parkinson's Gait

Also called Festinating Gait

SHort, shuffling steps
Knees, trunk, and neck in FLX
Arms move stiffly


The ROM that causes a patent pain is ALWAYS performed:



Define Gait Cycle

Sequence of motions that occurs btw tow consecutive initial contacts of the same foot

Stance phase 60%
Swing phase 40%


Stages of Stance Phase

Initial Contact (heel strike)
Load response (foot flat)
Midstance (single-leg stance)
Terminal Stance (heel off)
Pressing (toe off)


Stages of Swing Phase

Initial swing
Terminal Swing (deceleration)

Swing phase makes up 40% of the gait cycle


If the Hamstrings are weak during Terminal Swing:

Heel strike may be excessively harsh to lock the knee in EXT

(S1-S2 N root lesion)


If the Ankle Dorsiflexors are weak in Midswing:

Person would have steppage gait = hip flxs excessively so the toes can clear the ground


If the hip flexors are weak in Initial Swing phase:



The trunk mms thrust the pelvis forward to provide forward movement to leg


What structure provide the most stability in the lower limb during Swing Phase?

The Pelvis and hip provide the most stability

This phase is a non weight bearing, open kinetic chain
