Slap gait, also known as steppage gait, is a walking pattern characterized by the foot slapping the ground due to weakness in the muscles that lift the front part of the foot (dorsiflexors). This weakness causes the individual to lift their leg higher than normal to avoid dragging the toes, and then the foot slaps down onto the floor.
Causes of Slap Gait
The primary cause of slap gait is weakness or paralysis of the foot and ankle dorsiflexors. Common underlying conditions include:
- Nerve damage: This can be caused by conditions such as peroneal nerve palsy, sciatica, or diabetic neuropathy.
- Muscle disorders: Muscular dystrophy and other muscle-related diseases can weaken the dorsiflexor muscles.
- Spinal cord issues: Conditions affecting the spinal cord, such as spinal stenosis or multiple sclerosis, may lead to slap gait.
Characteristics of Slap Gait
- Foot Drop: The front part of the foot droops downwards.
- High Stepping: The person lifts their leg higher than normal when walking.
- Foot Slap: The foot slaps audibly against the ground upon contact.
