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.
