ABSTRACT

BACKGROUND: Children with idiopathic toe-walking, a common pediatric condition, walk some or all of the time on their toes. This condition often causes parental concern, with repeated medical contacts and a range of interventions including stretching, casts, injection of botulinum toxin A, and surgical procedures. The purpose of this cohort study was to document the natural history of this condition. METHODS: In a population-based cohort of 1,401 healthy 5.5-year-old Swedish children, we found the prevalence of idiopathic toe-walking to be approximately 5% (63 of 1,401). Of the 63 children who had ever been a toe-walker, 26 still were at the age of 5.5 years and were followed in the current study at 8 and 10 years of age. At the 8-year follow-up, parents were asked by telephone whether their child had received any treatment or diagnosis since the 5.5-year assessment, as well as to what extent (approximately 25%, 50%, 75%, or 100% of the time) the child still walked on the toes. At the visit when the children were 10 years of age, their parents were asked the same questions. All 26 children also underwent a neurological examination and an orthopaedic examination focusing on the lower extremities. RESULTS: At 8 years of age, 6 of 26 children had ceased toe-walking, and by the age of 10 years, 50 (79%) of the original 63 patients had spontaneously ceased toe-walking. Idiopathic toe-walking did not result in contractures of the triceps surae. One subgroup of children displayed early contracture of the ankle and should thus not be considered idiopathic toe-walkers. Four of the children who still toe-walked at the age of 10 years demonstrated some neurodevelopmental comorbidity. CONCLUSIONS: By the age of 10 years, 79% of the children who have ever been a toe-walker spontaneously develop a typical gait, without intervention or contractures of the ankle dorsiflexion. The diagnosis of short tendo Achilles should be retained as a separate diagnosis as there is a subset of children with this entity who should be treated early in childhood. Neurodevelopmental comorbidities are common among those who continue to toe-walk. LEVEL OF EVIDENCE: Prognostic Level I.

ABSTRACT

BACKGROUND: There are many treatments for idiopathic toe-walking, including casts with or without injection of botulinum toxin A. Combined treatment with casts and botulinum toxin A has become more common even though there have been few studies of its efficacy and safety problems. Our aims were to conduct a randomized controlled trial to test the hypotheses that combined treatment with casts and botulinum toxin A is more effective than casts alone in reducing toe-walking by patients five to fifteen years of age, and that the treatment effect correlates with the extent of coexisting neuropsychiatric problems. METHODS: All patients who had been consecutively admitted to the pediatric orthopaedics department of our institution because of idiopathic toe-walking between November 2005 and April 2010 were considered for inclusion in the study. Forty-seven children constituted the study population. The children were randomized to undergo four weeks of treatment with below-the-knee casts either as the sole intervention or to undergo the cast treatment one to two weeks after receiving injections of botulinum toxin A into the calves. Before treatment and three and twelve months after cast removal, all children underwent three-dimensional (3-D) gait analysis. The severity of the idiopathic toe-walking was classified on the basis of the gait analysis, and the parents rated the time that their child spent on his/her toes during barefoot walking. Passive hip, knee, and ankle motion as well as ankle dorsiflexor strength were measured. Before treatment, all children were evaluated with a screening questionnaire for neuropsychiatric problems. RESULTS: No differences were found in any outcome parameter between the groups before treatment or at three or twelve months after cast removal. Several gait-analysis parameters, passive ankle motion, and ankle dorsiflexor strength were improved at both three and twelve months in both groups, even though many children still demonstrated some degree of toe-walking. The treatment outcomes were not correlated with coexisting neuropsychiatric problems. CONCLUSION: Adding botulinum toxin-A injections prior to cast treatment for idiopathic toe-walking does not improve the outcome of cast-only treatment.

ABSTRACT

BACKGROUND: Idiopathic toe-walking (ITW) is a condition in which otherwise healthy children walk on their toes. The diagnosis is a diagnosis of exclusion. The aim of this study was to elucidate the occurrence of neuropsychiatric symptoms among 5- to 13-year-old children with ITW. METHODS: Fifty-one consecutive children (31 boys, 20 girls) with a mean age of 9 years and 1 month were referred to a pediatric orthopaedic unit for ITW. Evaluations included assessments by a pediatric orthopaedic surgeon and a pediatric neurologist and the parents were asked to complete the Five to Fifteen questionnaire, a validated screening tool for neuropsychiatric problems. The study cohort was compared with an age-matched normative group previously described. RESULTS: In the study group, the percentage of children scoring above the 90th percentile, indicating difficulties, were for the different domains; motor skills 39.0%, executive functions 17.6%, perception 25.5%, memory 23.5%, language 23.5%, learning 25.9%, social skills 25.5%, and emotional/behavioural problems 21.6%. CONCLUSIONS: Children with ITW as a group displayed more neuropsychiatric problems than a normative group of age-matched children. These findings merit future larger studies. Furthermore, when children with ITW are referred for orthopaedic or neurological assessment, a structured neuropsychiatric history is advisable and further neuropsychiatric investigations should be considered. LEVEL OF EVIDENCE: II.

ABSTRACT

BACKGROUND: Children walking on their toes instead of with a typical gait, without evidence of an underlying medical condition, are defined as idiopathic toe-walkers. The prevalence of idiopathic toe-walking is unknown. METHODS: A cross-sectional prevalence study of 5.5-year-old children (n = 1436) living in Blekinge County, Sweden, was performed at the regular 5.5-year visit to the local child welfare center. Children were assessed for a history of toe-walking or whether they still walked on their toes. Additionally, all 5.5-year-old children (n = 35) admitted to the clinic for children with special needs in the county were assessed. RESULTS: Of the 1436 children in the cohort (750 boys, 686 girls), 30 children (2.1%, 20 boys and 10 girls) still walked on their toes at age 5.5 years and were considered as active toe-walkers. Forty children (2.8%, 22 boys and 18 girls) had previously walked on their toes but had stopped before the 5.5-year visit and were considered as inactive toe-walkers. At age 5.5 years, the total prevalence of toe-walking was 70 (4.9%) of 1436. For children with a neuropsychiatric diagnosis or developmental delay, the total prevalence for active or inactive toe-walking was 7 (41.2%) of 17. CONCLUSIONS: This study establishes the prevalence and- early spontaneous course of idiopathic toe-walking in 5.5-year-old children. At this age, more than half of the children have spontaneously ceased to walk on their toes. The study confirms earlier findings that toe-walking has a high prevalence among children with a cognitive disorder.

ABSTRACT

BACKGROUND: Numerous recommendations have been made for treating idiopathic toe-walking (ITW), but the treatment results have been questioned. The purpose of this study was to investigate whether botulinum toxin A (BTX) improves the walking pattern in ITW as examined with 3-D gait analysis. PARTICIPANTS AND METHODS: A consecutive series of 15 children (aged 5-13 years) were enrolled in the study. The children underwent a 3-D gait analysis prior to treatment with a total of 6 units/kg bodyweight Botox(®) in the calf muscles and an exercise program. The gait analysis was repeated 3 weeks and 3, 6, and 12 months after treatment. A classification of toe-walking severity was made before treatment and after 12 months. The parents rated the perceived amount of toe-walking prior to treatment and 6 and 12 months after treatment. RESULTS: Eleven children completed the 12-month follow-up. The gait analysis results displayed a significant improvement, indicating decreased plantarflexion angle at initial contact and during swing phase and increased dorsiflexion angle during midstance at all post-treatment testing instances. According to the parents' perception of toe-walking, 3/11 children followed for 12 months had ceased toe-walking completely, 4/11 decreased toe-walking, and 4/11 continued toe-walking. After 6-12 months, the toe-walking severity classification improved in 9 of the 14 children for whom data could be assessed. CONCLUSIONS: A single injection of BTX in combination with an exercise program can improve the walking pattern in children with ITW seen at gait analysis, but the obvious goal of ceasing toe-walking is only occasionally reached.
