Test-Retest Reliability and Construct Validity of the German Translation of the Gait Outcome Assessment List (GOAL) Questionnaire for Children with Ambulatory Cerebral Palsy.

The Gait Outcome Assessment List (GOAL) is a patient or caregiver-reported assessment of gait-related function across different domains of the International Classification of Functioning, Disability, and Health (ICF) developed for ambulant children with cerebral palsy (CP). So far, the questionnaire is only available in English. The aim of this study was to translate the GOAL into German and to evaluate its reliability and validity by studying the association between GOAL scores and gross motor function as categorized by the gross motor function classification system (GMFCS) in children with cerebral palsy (CP). The GOAL was administered to primary caregivers of n = 91 children and adolescents with CP (n = 32, GMFCS levels I; n = 27, GMFCS level II; and n = 32, GMFCS level III) and n = 15 patients were capable of independently completing the whole questionnaire (GMFCS level I). For assessing test-retest reliability, the questionnaire was completed for a second time 2 weeks after the first by the caregivers of n = 36 patients. Mean total GOAL scores decreased significantly with increasing GMFCS levels with scores of 71 (95% confidence interval [CI]: 66.90-74.77) for GMFCS level I, 56 (95% CI: 50.98-61.86) for GMFCS level II, and 45 (95% CI: 40.58-48.48) for GMFCS level III, respectively. In three out of seven domains, caregivers rated their children significantly lower than children rated themselves. The test-retest reliability was excellent as was internal consistency given the GOAL total score. The German GOAL may serve as a much needed patient-reported outcome measure of gait-related function in ambulant children and adolescents with CP.

German translation of the caregiver priorities and child health index of life with disabilities questionnaire: test-retest reliability and correlation with gross motor function in children with cerebral palsy.

We aimed to translate the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) questionnaire into German and to evaluate its reliability and validity by studying the association between CPCHILD scores and gross motor function as measured by the gross motor function classification system (GMFCS) in children with cerebral palsy (CP). The original CPCHILD questionnaire and manual were translated and back translated. It was administered to primary caregivers of persons with CP (GMFCS levels III-V) and was completed a second time 2 weeks after the first to measure test-retest reliability (n = 17). Primary caregivers of 68 children with CP; GMFCS level III (n = 14), level IV (n = 28), and level V (n = 26) completed the questionnaire. Mean total CPCHILD scores across GMFCS levels were 67.1 ± 14.9 for GMFCS level III, 56.6 ± 11.8 for level IV, and 44.3 ± 12.9 for level V. Good correlation (r = - 0.56) was observed between GMFCS and total scores test-retest reliability showed intraclass correlation coefficients between 0.4 and 0.9. The German CPCHILD yielded similar test-retest reliability and score distributions across the GMFCS level as the original version. The best correlations were observed for domains that are close to the functional deficits.

Influence of the percutaneous myofasciotomy on gait of children with spastic cerebral palsy - A short term, retrospective controlled analysis.

BACKGROUND: One of the primary causes in children with cerebral palsy (CP) leading to gait disorders is an increased muscle tone which may secondary result in a shortening of the muscle fascia. Percutaneous myofasciotomy (pMF) is a minimal-invasive surgical intervention correcting the shortened muscle fascia and aims to extend the range of motion. RESEARCH QUESTION: What is the effect of pMF on gait in children with CP three months and one year post-OP? METHODS: Thirty-seven children (f: n = 17, m: n = 20; age: 9,1 ± 3,9 years) with spastic CP (GMFCS: I-III, bilateral (BSCP): n = 24, unilateral (USCP): n = 13) were retrospectively included. All children underwent a three dimensional gait analysis with the Plug-in-Gait-Model before (T0) and three months after pMF (T1). Twenty-eight children (bilateral: n = 19, unilateral: n = 9) underwent a one-year follow-up-measurement (T2). Differences in the Gait Profile Score (GPS), kinematic gait data, gait-related functions and mobility in daily living were statistically analyzed. Results were compared to a control group (CG) matched in age (9,5 ± 3,5 years), diagnosis (BSCP: n = 17; USCP: n = 8) and GMFCS-level (GMFCS I-III). This group was not treated with pMF but underwent two gait analyses in twelve months. RESULTS: The GPS improved significantly in BSCP-pMF (16,46 ± 3,71° to 13,37 ± 3,19°; p < .0001) and USCP-pMF (13,24 ± 3,27° to 10,16 ± 2,06°; p = .003) from T0 to T1 with no significant difference between T1 and T2 in both groups. In CG there was no difference in the GPS between the two analyses. SIGNIFICANCE: PMF may in some children with spastic CP improve gait function three months as well as for one-year post-OP. Medium and long-term effects, however, remain unknown and further studies are needed.

Dynamic Standing Exercise using the Innowalk Device in Patients with Genetic and Acquired Motor Impairments.

OBJECTIVE: For individuals with motor impairments, dynamic standing has been proposed as an opportunity for regular daily physical activity. The aim of this study was to analyse patient characteristics, indications, intensity of usage, desired objectives and outcomes of dynamic standing in daily clinical practice in order to form the basis for research regarding this treatment option. SETTING: Data were analysed from standardized questionnaires completed prospectively before supply of a home-based medical device for dynamic standing (Innowalk; Made for Movement GmbH, Langenhagen, Germany) and at the time of individual adaptations. PARTICIPANTS: In a retrospective chart analysis, records of 46 patients (50% cerebral palsy; 50% diverse syndromes) were evaluated. INTERVENTION: The Innowalk had been prescribed for either home-based use (n = 31), in therapeutic institutions (n = 8), or other settings (n = 7). Dynamic standing was performed for 10-30 min as a single session (n = 8) or for 20-60 min 11 [4-21] weeks in 36 patients. RESULTS: Improvements were found for: passive assisted motion (79%), stimulation of intestinal functions (71%), body stability (64%), joint mobility (56%), secure means of allowing supine position (52%), and revision of abnormal motion patterns (48%). CONCLUSION: Thus, this systematic approach shows usage patterns, indications, desired goals and clinical outcome of dynamic standing in daily clinical practice and forms the basis for the design of a prospective, randomized controlled trial.

Treatment failures and complications in patients with Blount disease treated with temporary hemiepiphysiodesis: a critical systematic literature review.

This systematic review sums up the state of knowledge about complications and reasons for failure when children with Blount disease are treated with temporary hemiepiphysiodesis. Twelve studies meet the inclusion criteria. The main reported obstacles were under correction and the poor predictability of the amount of correction that was obtainable. Obese patients with severe deformity are the most challenging groups of patients in the treatment of angular deformities. Patients with Blount disease require a careful evaluation regarding the deformity, age, body weight, and social background to reach the optimal treatment strategy. If hemiepiphysiodesis fails, osteotomy remains the preferred salvage procedure. LEVEL OF EVIDENCE: IV.

Does hip displacement influence health-related quality of life in children with cerebral palsy?

OBJECTIVE: To evaluate the association of hip lateralisation with health-related quality of life (HRQL) in children with cerebral palsy (CP) using the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD(®)) questionnaire. METHODS: We assessed n = 34 patients (mean age: 10.2 years, SD: 4.7 years; female: n = 16) with bilateral CP and Gross Motor Function Classification System (GMFCS) Level III-V using the CPCHILD(®) questionnaire. Hip lateralisation was measured by Reimer`s migration percentage (MP). RESULTS: There was an association between both, MP and GMFCS with CPCHILD(®) total score. Stratified analyses did not suggest interaction of the association between MP and CPCHILD(®) total score by GMFCS level. After adjustment for GMFCS level, we found a significant linear decrease of CPCHILD(®) total score of -0.188 points by 1% increment in MP. CONCLUSIONS: There was an association between MP and HRQL, which could not be explained by the GMFCS level.
