In this study we aimed to characterize muscle composition of the medial gastrocnemius in children with spastic cerebral palsy (SCP) using quantitative ultrasound.Forty SCP, aged 4-14 years, participated study. Children were grouped according gross motor function classification system (GMFCS I-V) and compared a cohort age- gender-matched, typically developing (TD; n = 12). Ultrasound scans taken gastrocnemius. Images then characterized grayscale statistics determine mean echo intensity (EI)...
This study aimed to track alterations in muscle volume for 6 months children with cerebral palsy (CP) after the first exposure botulinum neurotoxin A (BoNT-A), a commonly used focal spasticity treatment.Eleven ambulant (eight males, three females) spastic CP, mean age 8 years 10 (SD 3y 1mo) participated. Participants received injections affected gastrocnemius. The of gastrocnemius, soleus, tibialis anterior, and hamstrings was measured using magnetic resonance imaging. Muscle normalized bone...
Aim To determine if neuromuscular electrical stimulation ( NMES ) applied to the ankle dorsiflexors during gait improves muscle volume and strength in children with unilateral spastic cerebral palsy CP ). Method Thirty‐two (15 females, 17 males; mean age 10y 8mo, range 5y 5mo–18y 1mo) a Gross Motor Function Classification System of level I or II were randomly assigned either 8‐week daily treatment group control (usual conventional treatments). Outcomes at week 8 (post‐ 14 (carryover)...
Botulinum toxin A (BoNTA) is routine treatment for hypertonicity in children with cerebral palsy (CP).This single-blind, prospective, cross-sectional study of 10 participants (mean age 11 years 7 months) was done to determine the relationship between muscle histopathology and BoNTA treated medial gastrocnemius CP. Open biopsies were taken from vastus lateralis (control) during orthopedic surgery.Neurogenic atrophy seen 6 4 months 3 post-BoNTA. Type 1 fiber loss type 2 predominance...
The purpose of this study was to determine the orthotic and therapeutic effects daily community applied FES ankle dorsiflexors in a randomized controlled trial. We hypothesized that children receiving eight-week treatment would demonstrate gait spasticity as well better mobility balance skills compared controls not FES. This trial involved 32 (mean age 10 yrs 3 mo, SD mo; 15 females, 17 males) with unilateral spastic cerebral palsy Gross Motor Function Classification System I or II randomly...
Abstract Background: A delay in the diagnosis of developmental dislocation hip has many long‐term consequences. This retrospective study was undertaken order to establish an incidence late‐presenting Western Australia, and investigate possible causes for missed diagnoses. Method: Data were collected retrospectively from 1 January 31 December 2010. Theatre records searched operative descriptions including words ‘arthrogram hip’, ‘EUA ‘closed reduction ‘open hip’ ‘spica’. Medical checked...
The aim of this paper is to determine whether daily functional electrical stimulation (FES) effective in improving self-perceptions individually identified mobility performance problems children with unilateral spastic cerebral palsy (USCP). We hypothesized that receiving 8 weeks FES treatment would have higher scores for self-perceived and satisfaction on the Canadian Occupational Performance Measure (COPM) priorities than not FES.
In this study we aimed to determine the lower limb morphological characteristics of skeletal muscle ambulant children with spastic cerebral palsy (CP) and typically developing (TD) children.Seventeen diplegic CP (10 boys 7 girls, 5-12 years age, Gross Motor Function Classification System [GMFCS] level I or II) 19 TD (8 11 5-11 age) underwent T1-weighted MRI. Morphological triceps surae, including volume, anatomical cross-sectional area, length, subcutaneous adipose tissue, were digitally...
Introduction This audit aimed to increase understanding of the long-term outcomes evidence-based medical and surgical interventions improve gross motor function in children adolescents with Cerebral Palsy.Methods Retrospective a birth cohort (2000–2009) attending tertiary service Western Australia.Results The comprises 771 patients aged 8 17 years. Percentage receiving no Botulinum Toxin treatments each Gross Motor Functional Classification System level was: I: 40%, II: 26%, III: 33%, IV:...
Management of common childhood spiral tibial fractures, known as toddler's has not significantly changed in recent times despite the availability immobilisation devices controlled ankle motion (CAM) boots. We compared standard therapy with these on quality-of-life measures.A prospective randomised trial, comparing an above-knee plaster Paris cast (AK-POP) a CAM boot children aged 1-5 years proven or suspected fractures presenting to tertiary paediatric ED Perth, Western Australia, between...
Abstract Background Children with severe disability often develop osteoporosis and have an increased risk of fracture. In Rett syndrome, the prevalence fracture is four times greater than in general population, femur commonly affected. This study used qualitative methods to investigate regaining mobility within 12 months following femoral syndrome parent caregiver experiences. Methods Caregivers ( n = 14) cases registered Australian Syndrome Database a daughter were recruited if their...
A 14-year-old girl with cerebral palsy presented for bilateral lower limb surgery spasticity. lumbar epidural catheter was sited under general anaesthesia on the third attempt and used intra-operatively good effect. local anaesthetic infusion postoperative analgesia but noted to be leaking dressing a patchy, unilateral block. The therefore removed second day. Following discharge, patient progressively developed new back leg pain which she re-admitted seven weeks later. This investigated...
Currently, our knowledge of standard data for muscle morphology in children is largely limited to the 1969 article by Brooke and Engel (BE). In 2016, we reported normal from vastus lateralis biopsies ambulant with cerebral palsy (CP). This report compares biopsy results against BE value criteria.Single-blind prospective cross-sectional study design.Results taken CP were according morphometry light electron microscopy; however, only 5 10 fulfilled criteria.This short highlights requirement...
<h3>Background and aims</h3> Distal forearm fractures are a common injury of childhood. They traditionally treated in plaster Paris back slab (POP) referred for orthopaedic follow up. Evidence shows these may be removable splints without A pathway splinting such with fabric metal was introduced our department. Aims were to reduce return trips hospital up decreasing disruption families, free medical nursing time ultimately produce an economic benefit the hospital. <h3>Methods</h3> control...
The combination of the Ponseti method with functional treatment produces better results and may reduce need for surgery. objective this study was to assess impact manipulation a congenital equinovarus clubfoot performed before correction by method. This cohort children <5 years treated followed over minimum period 1 year. Each foot according parameters were as follows: age, gender, concept previous treatment, manipulation, degree deformation Pirani score, laterality deformation, number casts...
