Is equinus related to CP?

Often — yes. Equinus develops in more than 50% of children with diplegic CP as a consequence of increased calf muscle tone. In these cases work with equinus runs in parallel with the core neuro-rehabilitation program — treating the deformity in isolation in a CP child is irrational. Equinus also occurs isolated (idiopathic toe walking) — here the approach is local.

In children under 6–7 years surgery is rarely needed: equinus responds well to conservative correction. Surgical Achilles tendon lengthening is an option for adolescents with a fixed form and ineffective conservative therapy. Whether surgery is needed is decided individually based on the examination findings.

Yes, as part of a comprehensive program. Biomechanical insoles with a heel lift offload the calf muscle, redistribute load, and help the child place the foot correctly. On their own insoles will not resolve equinus, but combined with stretching, orthoses, and (in CP) the core program they produce a meaningful functional shift.

Treatment of Equinus in Huizhou

Equinus foot is a common deformity in CP and idiopathic toe walking. At NeuroLife Huizhou we use a combined approach: modified Ponseti for myotonic correction of Achilles tendon shortening, custom biomechanical insoles for load redistribution, and 3D orthoses for severe cases. Often co-occurs with CP — we treat both conditions in parallel.

About the condition

What is Equinus Foot?

Equinus foot (pes equinus) is a deformity in which the foot is fixed in plantar flexion, and the child cannot fully place the heel on the floor. ICD-10 lists it under Q66.8 (other congenital foot deformities), but it is also common as an acquired form against a background of spasticity in CP. This is exactly why the approach depends on the cause of the deformity.

At NeuroLife Huizhou we distinguish three variants of approach:

Isolated idiopathic equinus (toe walking) without neurological disorders — the modified Ponseti method: a series of casts to gradually bring the foot to neutral at 5–7 day intervals, with a minimally invasive percutaneous Achilles tenotomy when needed;
Equinus on a background of CP spasticity — local correction (biomechanical insoles with a heel lift, nighttime orthoses, therapeutic massage, and physiotherapy) runs in parallel with the core neuro-rehabilitation program; correcting the deformity in isolation in a CP child is irrational;
Fixed severe forms in older children — surgical Achilles tendon lengthening at a specialized clinic, followed by a return to the recovery program.

The combined expertise of the Yuncheng Orthopedic Research Institute (Assoc. Prof. Liu Hejian) and the Huizhou neuro-rehabilitation team allows us to work with equinus at any level — from isolated toe walking to a severe form in tetraplegia. Early presentation and a systematic approach nearly always produce a functional result: the child places the heel down, walks without the characteristic abnormal gait, and can run.

Causes

Spasticity of the calf muscles and contractures in CP are the most common cause in children. Also: congenital Achilles tendon shortening (isolated or syndromal), idiopathic toe walking without neurological disorders, post-traumatic scar changes, neuromuscular diseases (SMA, DMD).

Symptoms

Toe walking, inability to lower the heel during walking and standing, restricted dorsiflexion at the ankle, asymmetric gait in unilateral forms, rapid fatigue, sometimes pain on activity. In CP children equinus is combined with other spastic patterns.

Diagnostics

Clinical examination with the Silverskiöld test to differentiate gastrocnemius vs soleus shortening, gait analysis (video) to assess kinematics, dorsiflexion range measurement. With a suspected neuromuscular component — neurological examination, EMG. In CP children — GMFCS staging.

Prognosis

With early initiation — a full functional result: the heel is placed on the floor, the child walks without limping. In CP children equinus is controlled but requires a regular maintenance program — without it spasticity returns. Neglected fixed forms in adolescents need surgery (open Achilles tendon lengthening) with subsequent extended recovery.
