- Nerve Compression: Pressure on the peroneal nerve, which governs dorsiflexion, can cause foot drop. Tight shoes, injuries, or anatomical issues may cause this compression.
- Nerve injuries: Knee or lower leg trauma might damage the peroneal nerve, causing foot drop.
- Neurological Disorders: Stroke, MS, and spinal cord injuries can impair brain-foot muscle connections.
- Muscle problems: Muscular dystrophies and other muscle problems can weaken foot muscles, causing foot drop.
- Sciatica, which branches into the peroneal nerve, can cause foot drop.
Symptoms:
Difficulty elevating the front half of the foot while walking, resulting in dragging or slapping.
Avoiding stumbling by raising the knee or swinging the leg.
