Idiopathic toe walking: a kinematic and kinetic profile

Area of Science:

• Pediatric Orthopedics
• Neurology
• Biomechanics

Background:

• Idiopathic toe walking (ITW) is a common diagnosis in children, often diagnosed by exclusion.
• Differentiating ITW from mild spastic diplegia is crucial for appropriate management.

Purpose of the Study:

• To characterize idiopathic toe walking (ITW) using quantitative gait analysis.
• To determine if children with ITW can normalize their gait patterns.

Main Methods:

• Quantitative gait analysis was performed on 51 neurologically normal children diagnosed with ITW.
• Gait data were collected during self-selected toe-walking and attempted normal heel-toe walking.
• Datasets were compared to assess gait normalization and with historical controls.

Main Results:

• Significant kinematic and kinetic deviations at the ankle were observed in self-selected toe walking.
• All children exhibited disruption of ankle rockers and a plantar flexion bias.
• 17% normalized all gait variables, while 70% normalized some variables when attempting a heel-toe gait.

Conclusions:

• Quantitative gait analysis effectively distinguishes ITW from mild cerebral palsy.
• Kinematic and kinetic differences at the knee and ankle are key diagnostic indicators.
• The majority of children with ITW demonstrate an ability to normalize some gait parameters on demand.
