In-toeing and Gait Problems in Children (Gait Analysis)

Intoeing means a child's toes turn towards the body's midline when walking or running. Families often describe feet "pointing inwards" or "catching each other when running". It is a common reason for consultation, with no underlying disease in the great majority.

Intoeing is not a single problem; it may arise at three different levels. Common causes are forward rotation of the thighbone at the hip (femoral anteversion), inward twisting of the shinbone below the knee (tibial torsion) and inward curvature of the forefoot (metatarsus adductus). Examination identifies the responsible level, and this distinction affects the expected course.

A child's gait matures over years. A new walker has a wide stance, short steps and unstable balance; foot alignment is also still developing. An appearance considered normal in a two-year-old may therefore require assessment in an eight-year-old.

Intoeing itself is usually painless and does not limit the child. Assessment is recommended in the following situations:

• Intoeing on only one side or a marked difference between sides
• Associated pain, limping, frequent falls and easy fatigue
• The deformity does not become less noticeable with age and may even increase
• A child who always walks on tiptoe or never puts their heel on the ground
• Regression in walking ability and inability to do things previously possible
• Other delays in strength, balance, speech or motor development

The three main causes typically occur at different ages, helping families understand what to expect.

Assessment starts by observing the child walking and running. Hip inward and outward rotation, lower-leg alignment and foot shape are then measured individually while the child is lying down. These measurements indicate the level causing intoeing. Muscle strength, joint flexibility, reflexes and the spine are also assessed because some gait disorders arise from the muscles or nervous system rather than bone alignment.

X-rays are often unnecessary for typical intoeing. Imaging is requested for one-sided cases, associated pain and limping, suspected hip disease or marked bowing of the legs. Assessment for families coming from Ordu and the surrounding area is planned in one visit; measurements are recorded at the first examination and compared with the same measurements at follow-up.

Gait analysis examines a child's walking step by step. Its basic form is clinical gait assessment: the child walks and runs over a set distance while stride length, the sequence of foot contact, knee and hip movement and trunk balance are observed. Video may be recorded and reviewed in slow motion if needed.

More advanced computerised gait analysis is available at specially equipped centres, producing numerical data from motion cameras, pressure platforms and muscle activity measurements. It is not necessary for every child; it is generally useful for complex gait disorders associated with neuromuscular disease and for surgical planning.

Gait analysis aims to identify the anatomical source of a finding and measure change over time, not to sell a device. Clinical assessment and regular review are usually sufficient for simple in-toeing.

This is the question families ask most often. For the commonest forms of in-toeing, the initial approach is regular monitoring rather than treatment. In most children, the finding decreases with growth and maturation of bone alignment. Sport, running and play are not restricted during this period.

There is no strong scientific evidence that insoles or products described as 'orthopaedic shoes' correct twisting of the bones or rotation of the femur. Insoles may reduce symptoms in specific situations such as painful flexible flat feet, pressure-distribution problems or a painful area within the foot. The aim is to treat the symptoms rather than the appearance.

For questions about foot shape, see flat feet; for big-toe deviation, see hallux valgus.

Sitting with both legs folded to the sides in a 'W' shape is common in children with increased femoral rotation. Although there is no conclusive evidence that this position causes intoeing, encouraging sitting cross-legged or with the legs extended forwards is a harmless recommendation.

Shoes that support the heel, have flexible soles and do not squeeze the foot are sufficient; expensive specialist products are unnecessary. Cycling, swimming and running are encouraged to support muscle development and balance. In the absence of significant symptoms, an annual review is sufficient for most children; attending the same centre helps measurements to be compared.
