  1. Pathomechanics of Gait and Dynamic Postures part I Dr .Manal Radwan Salim Lecturer of Physical Therapy Pharos University

  2. COMMON GAIT ABNORMALITIES A. Antalgic Gait. B. Lateral Trunk bending. C. Functional Leg-Length Discrepancy. D. Increased Walking Base. E. Inadequate Dorsi flexion Control. F. Excessive Knee Extension.

  3. COMMON GAIT ABNORMALITIES Cont.:A. Antalgic Gait -Gait pattern in which stance phase on affected side is shortened -Corresponding increase in stance on unaffected side -Common causes: OA, tendinitis

  4. COMMON GAIT ABNORMALITIES cont.:B.Lateral Trunk bending’Trendelenberg gait Usually unilateral, if Bilateral = waddling gait Common causes: A. Painful hip B. Hip abductor weakness C. Leg-length discrepancy D. Abnormal hip joint

  5. COMMON GAIT ABNORMALITIES Cont.:C.Functional Leg-Length Discrepancy Swing leg: longer than stance leg: Causes dicussed in details in muscle weakness 4 common compensations: A. Circumduction B. Hip hiking C. Steppage D. Vaulting

  6. COMMON GAIT ABNORMALITIES Cont.:D. Increased Walking Base • Normal walking base: 5-10 cm • Common causes: • Deformities • Abducted hip • Valgus knee • Instability • Cerebellar ataxia • Proprioception deficits

  7. COMMON GAIT ABNORMALITIES Cont.: E. Inadequate Dorsiflexion Control • In stance phase (Heel contact – Foot flat): Foot slap • In swing phase (mid-swing): Toe drag • Causes: • Weak Tibialis Ant. • Spastic plantarflexors

  8. COMMON GAIT ABNORMALITIES:F. Excessive knee extension Loss of normal knee flexion during stance phase Knee may go into hyperextension Genu recurvatum: hyperextension deformity of knee Common causes: Quadriceps weakness (mid-stance) Quadriceps spasticity (mid-stance) Knee flexor weakness (end-stance) * * *
