Foot Drop
Foot Drop
Foot drop is a gait abnormality in which the front part of the foot cannot be lifted due to weakness or paralysis of the muscles that control dorsiflexion. Rather than a condition in itself, foot drop is a sign of an underlying neurological, muscular, or anatomical issue. An ankle foot orthosis (AFO) can restore near-normal gait, prevent tripping and falls, and dramatically improve independence and quality of life.
Common Causes of Foot Drop
- Stroke, causing muscle weakness on one side of the body (hemiplegia)
- Multiple sclerosis (MS) affecting motor nerve pathways
- Peroneal nerve injury from knee or hip fracture, surgery, or compression
- Herniated lumbar disc or spinal stenosis at L4–L5
- Charcot-Marie-Tooth disease and other hereditary neuropathies
- Cerebral palsy affecting lower limb motor control
- Polio and post-polio syndrome
Common Symptoms:
- Dragging the toes when walking, causing tripping
- Steppage gait — exaggerated lifting of the knee to clear the foot
- Slapping the foot against the ground with each step
- Weakness or numbness on the top of the foot and shin
- Difficulty going up stairs or walking on uneven ground
- Increased risk of falls
How Is Foot Drop Treated?
- Ankle foot orthosis (AFO) to assist dorsiflexion during the swing phase
- Physical therapy to strengthen remaining dorsiflexor muscles
- Functional electrical stimulation (FES) devices
- Orthotics and adaptive footwear
- Surgical correction of the underlying nerve or tendon issue
- Tendon transfer surgery in chronic cases
- Treatment of the underlying neurological condition
How an AFO Helps Foot Drop:
An ankle foot orthosis holds the foot at a 90-degree angle relative to the leg, preventing the toe from dragging during the swing phase of gait. This simple mechanical correction restores a near-normal walking pattern, reduces energy expenditure, and dramatically lowers fall risk. RCAI manufactures a range of AFOs — from flexible thermoplastic designs for mild foot drop to solid AFOs for complete dorsiflexion loss — each custom-fitted to the patient's anatomy and functional needs, and handcrafted at our St. Petersburg, Florida facility.
