Das

100

Maximum PF into DF (concentric ant tib) 

Peak knee flexion occurs, uniquely timed for optimal clearance of the foot 

Hip: flexes- assists foot clearance 

Initial swing 

200

Ankle dorsiflexion controlled by eccentric contraction of the soleus muscle

knee extends

vastus medialis, intermedius, and lateralis stabilize the knee until the ground reaction force passes anterior to the knee joint 

hip continues to extend 

Midstance 

300

Initial contact on one foot to initial contact of the other foot 

Step length

400

Audible slap at initial contact

Foot slap 

500

Usually from spasticit5y, bilateral hip adduction 

Scissoring gait 

It

100

Ankle: neutral dorsiflexion 

Knee: minimal flexion 

Hip: about 30 deg flexion 

Gluteus maximus and hamstrings control hip

hamstrings prevent knee hyperextension (eccentric) 

Anterior tib and quads initiate the loading response (eccentric) 

Initial contact 

200

Ankle: begins to PF eccentric ant tib positions ankle in neutral 

Knee: extension from eccentric hamstrings decelerate the forward swing of the thigh; quads become active to assist with control of the knee 

Hip: minimal movement noted 

Terminal swing 

300

Distance between feet in the frontal place 

Base of support 

400

Lateral deviation of swing 

Circumduction 

500

Uncoordinated, not-smooth

Ataxic gait 

For

100

Ankle: PF 

knee: flexing to about 45 deg at toe-off 

Hip: begins to flex, concentric hip flexors, primarily the iliopsoas; rectus femoris muscle is active to augment hip flexion at faster walking speeds 

Pre-swing 

200

Initial contact of one foot to initial contact of the same foot 

Stride 

300

1. Head to toe or toe to head 

2. look at all body segments 

3. be systematic 

4. be consistent 

5. only report what is observed! (Make no assumptions) 

Observational gait analysis rules 

400

Hip, knee, ankle flex, hip adduction 

Crouched gait 

500

Avoiding weight bearing on one limb 

Antalgic gait 

This

100

Ankle: DF - concentric ant tib 

Knee: extending by INERTIAL forces without muscle activity 

Hip: concentric flexion 

Mid swing 

200

Toeing in/out 

Step angle 

300

Hip drop in midstance

Trendelenburg 

400

Elevation of pelvis during swing 

Hip hiking 

Section

100

Forward progression of the tibia is slowed/stopped and further increase in dorsiflexion is limited 

ankle DF decreases by concentric contraction of the gastrocnemius and soleus 

knee moves from relative extension to increasing flexion during terminal stance 

hip continues to extend 

Terminal stance 

200

Hip controlled through concentric glut max, glut min and hamstring coming into extension

Knee flexes 15 deg to absorb shock 

eccentric quad to control knee flexion 

Forefoot lowers to the ground through eccentric anterior tib 

Loading response 

300

Distance between midline and step in frontal plane 

Step width 

400

Lack of DF during swing
