Abnormal Walking
The normal child begins to walk at 12 to 14 months of age. Initially it is normal for the child to walk with a wide-based, externally rotated gait, taking numerous short steps. The gait then undergoes orderly stages of development. Walking velocity, step length and the duration of the single-limb stance increase with age and the number of steps taken per minute decreases. A mature gait pattern is well established by about 3 years of age, and the gait of a seven-year-old child resembles that of an adult. A normal mature gait cycle consists of the stance phase, during which the foot is in contact with the ground and the swing phase, during which the foot is off the ground.
Description | Potential causes | |
Antalgic gait | Due to pain on the affected side. May present with limp or non-weight bearing.A stiff jointed gait may result from arthritis. |
|
Trendelenberg gait | Results from hip abductor muscle weakness. Whilst weight-bearing on ipsilateral side, the pelvis drops on contralateral side (rather than rising as is normal).With bilateral hip disease - a waddling "rolling sailor" gait can be seen (with hips, knees and feet externally rotated). Can also be secondary to painful hip conditions. |
|
Circumduction gait("peg leg") | Due to excessive hip abduction as the leg swings forward creating a semi-circular movement of the leg. |
|
Waddling gait | A wide based gait with lumbar lordosis suggests proximal muscle weakness. |
|
Spastic gait | Stiff walking and the foot is seen to be inverted and dragged along. Often accompanied by flexion of upper limbs. |
|
Ataxic gait | Instability and alternating between a narrow to wide base of gait. |
|
Toe-walking gait ("equinus") | Walking on tip-toe with lack of heel contact. |
|
High Steppage gait | Abnormal foot posture with toes pointing down. Foot drop due to loss of dorsiflexion. |
