29 Cards in this Set
- Front
- Back
Base (step) width |
Distance between the 2 ft (normal 5-10cm) Wider base - suspect pathology that results in Poor blance With increase speed base decreases to 0 and might even cross over |
|
Step length |
Distance btwn contact points on opposite fees (~72cm) |
|
Stride length |
Linear distance in plan if progress between successive foot to floor contact of same foot (~144cm) Decreases with age, pain and fatigue |
|
Cadence |
Total number of full cycles taken within given amount of time |
|
Lateral pelvic shift durning gait |
Side to side movement of pelvis durning gait Normal 2-5cm Increases if feet are further apart |
|
Vertical pelvic shift of gait |
Keep COG from moving up and down more than 5cm during gait High point: mid stance Low point: inital contact |
|
Stride length |
Linear distance between successive foot to floor contact of same foot (144cm) |
|
Pelvic rotation |
Lessen angle of femur with the floor and therefore lengthens femur |
|
3 reasons for Abnormal gait |
1. Pathology or 8njury of specific join/structure 2. Compensation for injury or pathology in other joint or structure 3. Compensation for 8njury or pathology in opposite limb |
|
Antalgic gait |
"normal" limp (painful gait) Self protection |
|
Arthrogenic gait |
Stiff hip or knee Results from stiffness, laxity or deformity May be painful may not be Pelvis must be elevated by exaggerate plantar flexion if opposite ankle and circumduction of stiff leg |
|
Ataxic gait |
Poor sensation it lack of muscle coordination Tendency towards poor balance and broad base Gait all is irregular, jerky, weaving E.g. cerebellar ataxia and sensory ataxia
|
|
Cerebellar ataxia |
Lurch or stagger gait (all movements exaggerated) |
|
Sensory ataxia |
Feet slap the ground, patient watches feet while walking |
|
Contracture gait |
Occur if immobilization has been prolonged or pathology of joint/structure has not been properly taken care of Hip flexor, knee flexor or plantar flexion contracture |
|
Hip flexion contracture gait |
Increase lordosis, extension of trunk combined with knee flexion to get foot off the ground |
|
Knee flexion contracture |
Excessive ankle dorsiflexion from late swing to early stance in uninvolved leg Early heel raise in terminal stance on involve stide |
|
Plantar flexion contracture gait |
Knee hyperextension in mid stance on affected leg, forward bending of trunk in mid stance to terminal stance of affected side |
|
Equinus gait |
Toe waking Weight bearing Primarily on lateral edge of foot. WB on injuried foot decreased. Pelvis and femur are laterally rotates to compensate for foot medial rotation |
|
Gluteus maximus gait |
Patient thrust posteriorly at heel strike to main hip extension of stance let Gait invokes backward lurch of trunk Present when gluteus maximus is weak |
|
Trendelenburg gait |
Aka gluteus medius gait (due to weakness) Excessive lateral pelvic list "Chorus girl swing" Positive Trendelenburg sign Remember the "sound side sags" |
|
Trendelenburg sign |
Contralateral pelvis drops due to ispilateral abductors not able able to stabilize or prevent drop |
|
Parkinsonian gait |
Neck, trunk and knee flex CHaracterized by shuffling or short rapid steps Arms stiff Durning gait patents leans forward and walks progressively faster |
|
Plantar flexor gait |
Plantar flexor unable to function - lack of LL jt. Stability - decreased/absent push off - stance phase decreased - shorter step length on unaffected side |
|
Psoatic limp |
-paitents with hip pathologies - weak reflex inhibition of psoas major - difficulty in swing through - may have exaggerated trunk/pelvic movement , - hip external rotation, flexion and adduction |
|
Quadriceps avoidance gait |
- Severe injury to quad (compensate with trunk and LL) - Forward flexion if trunk and strong ankle plantar flexion cause knee to hypertension |
|
Scissor gait |
- Result of spastic paralysis of hip adductors - Causes knees to draw together to leg swing with great effort |
|
Short leg gait |
Result of one leg shorter than the other -lateral shift to affected side (limp) - supination of foot on affected side - joints on unaffected side may demestrate exaggerat d flexion |
|
Steppage gait |
Aka Drop foot - weka or paralyzed dorsiflexion mucles - knee lifted higher. - at initial contract foot slaps ground (drop foot) |
