Foot Care for People with Cerebral Palsy: Spasticity, Equinus, and Orthotics

Foot Management in Cerebral Palsy: A Lifelong Consideration

Cerebral palsy (CP) — the spectrum of nonprogressive motor disorders resulting from early brain injury — affects foot function through upper motor neuron pathology that causes spasticity, weakness, and coordination dysfunction. The foot manifestations of CP vary by CP type (spastic, dyskinetic, ataxic) and distribution (hemiplegia, diplegia, quadriplegia), but equinus and associated foot deformities are nearly universal in spastic CP and require lifelong management. At Balance Foot & Ankle in Howell and Bloomfield Township, Michigan, we provide foot care for children and adults with CP in collaboration with neurology, physical therapy, and orthopedic surgery.

Equinus: The Most Common CP Foot Deformity

Equinus — plantarflexion deformity from spastic gastrocnemius-soleus complex — is the defining foot problem in spastic CP. The spastic calf prevents ankle dorsiflexion, causing toe-walking (if mild) or complete inability to achieve heel contact with the ground (if severe). True equinus (fixed contracture) must be distinguished from dynamic equinus (toe-walking that can be manually corrected to neutral) — the distinction affects treatment. Dynamic equinus responds to orthotics and Botox; fixed equinus requires serial casting, Botox, or surgical lengthening. Calf stretching (daily stretching programs, serial casting) prevents fixed contracture development in younger children. Solid AFOs (ankle foot orthoses) that maintain the ankle at neutral are the orthotic cornerstone for equinus management.

Associated Foot Deformities

CP-related foot deformities beyond equinus include: valgus hindfoot (heel turns outward — common in diplegia) requiring medial-lateral correction in AFO posting or subtalar joint-blocking orthotics. Varus hindfoot (heel turns inward — more common in hemiplegia). Planovalgus flat foot from the combined effects of spasticity and ligamentous laxity. Hallux valgus and toe deformities from intrinsic muscle imbalance. The deformity pattern evolves through childhood as the skeletal system grows under the influence of spastic muscle forces — regular monitoring and orthotic adjustment are necessary throughout growth.

Botox and Surgical Management

Botulinum toxin (Botox) injection to spastic calf muscles temporarily reduces spasticity, allowing better AFO tolerance, improved gait pattern, and more effective physical therapy — typically used in children to delay surgical intervention or bridge to the next growth phase. Surgical intervention is considered for fixed contractures not managed by conservative means, recurrent deformity, or function-limiting problems in appropriate candidates: gastrocnemius or Achilles lengthening for equinus, tendon transfers for varus or valgus imbalance, and bony procedures for structural correction in skeletal maturity.

Most Common Mistake We See

The most common mistake we see is: Wearing new orthotics all day from day one. Fix: break-in schedule of 2 hours on day one, adding 2 hours per day until full-day tolerance.
