Aim Botulinum toxin type A (BoNT‐A) injections were used in the treatment of lower‐limb spasticity in children with cerebral palsy (CP). Anecdotal evidence suggests a reduction in pain after this treatment in children who had pain localized to a displaced hip joint. We report on our current clinical practice.
Method Twenty‐six children with non‐ambulant quadriplegic CP (Gross Motor Function Classification System level V) were assessed as having significant spasticity and pain at the hip level. Twelve were males and 14 females, with an age range of 2 to 19 years (mean age 11y 6mo, SD 4y 9mo). Ten had functional difficulties secondary to predominant spasticity and 16 had a mix of a high‐background peripheral tone with superimposed dystonia. Of the 26 children assessed, 10 had at least one hip which was dislocated and three had at least one hip which was subluxed. As part of their spasticity management programme they received targeted BoNT‐A injections to the adductor magnus, medial hamstrings and iliopsoas muscle groups. The Paediatric Pain Profile was used as the primary outcome measure.
Results All had highly significant improvement in their recorded pain profile scores measured at 3 months after treatment (p<0.001). There was equal efficacy in response to treatment in the children with subluxed or dislocated hips. In addition, families commented on improved quality of life for the children across several areas, including sleep, postural management, and activities of daily living.
Interpretation This report demonstrates that targeted BoNT‐A injections reduced pain in children with significant spasticity and pain at the hip level. They may also improve quality of life of non‐ambulant children with CP and a hip problem.
BackgroundThe evidence base to guide the pharmacological management of tone and abnormal movements in cerebral palsy (CP) is limited, as is an understanding of routine clinical practice in the UK. We aimed to establish details of motor phenotype and current pharmacological management of a representative cohort across a network of UK tertiary centres.MethodsProspective multicentre review of specialist motor disorder clinics at nine UK centres, collecting data on clinical features and pharmacological management of children and young people (CYP) with CP over a single calendar month.ResultsData were collected from 275 CYP with CP reviewed over the calendar month of October 2017. Isolated dystonia or spasticity was infrequently seen, with a mixed picture of dystonia and spasticity ± choreoathetosis identified in 194/275 (70.5%) of CYP. A comorbid diagnosis of epilepsy was present in 103/275 (37.4%). The most commonly used medications for abnormal tone/movement were baclofen, trihexyphenidyl, gabapentin, diazepam and clonidine. Medication use appeared to be influenced separately by the presence of dystonia or spasticity. Botulinum toxin use was common (62.2%). A smaller proportion of children (12.4%) had undergone a previous neurosurgical procedure for tone/movement management.ConclusionsCYP with CP frequently present with a complex movement phenotype and comorbid epilepsy. They have multiple therapy, medical and surgical management regimens. Future trials of therapeutic, pharmacological or surgical interventions in this population must adequately encompass this complexity in order to be translatable to clinical practice.
