The Functional Mobility Scale (FMS).

We devised a new Functional Mobility Scale (FMS) to describe functional mobility in children with cerebral palsy, as an aid to communication between orthopaedic surgeons and health professionals. The unique feature of the FMS is the freedom to score functional mobility over three distinct distances, chosen to represent mobility in the home, at school and in the wider community. We examined the construct, content, and concurrent validity of the FMS in a cohort of 310 children with cerebral palsy by comparing the FMS to existing scales and to instrumented measures of physical function. We demonstrated the scale to be both valid and reliable in a consecutive population sample of 310 children with cerebral palsy seen in our tertiary referral center. The FMS was useful for discriminating between large groups of children with varying levels of disabilities and functional mobility and sensitive to detect change after operative intervention.

A systematic review of measures of activity limitation for children with cerebral palsy

This systematic review critically appraises the literature on the psychometric properties and clinical utility of evaluative activity limitation outcome measures used for children with cerebral palsy (CP). The search strategy yielded 29 articles for eight outcome measures that met the inclusion criteria for the review. The Gross Motor Function Measure and Activities Scale for Kids were found to have sound psychometric properties in most areas. Reliability was found to be adequate for all tools. For the CP population, further examination of some aspects of validity is required for the Child Health Questionnaire (CHQ), Functional Assessment Questionnaire (FAQ), Functional Mobility Scale (FMS), Pediatric Evaluation of Disability Inventory, Pediatric Outcomes Data Collection Instrument (PODCI), and the Functional Independence Measure for Children. The FAQ, CHQ, FMS, and PODCI were found to require further examination for responsiveness. Clinical utility of the measures varied. The FMS was the only one to differentiate between function in the home, school, and community and to consider different assistive devices. These findings suggest that a range of measures is required to evaluate activity, and assessment should be tailored to the individual needs of children with CP.

The Functional Mobility Scale: ability to detect change following single event multilevel surgery.

The aim of this study was to examine the ability of the Functional Mobility Scale (FMS) to detect change in children with cerebral palsy (CP) undergoing single event multilevel surgery (SEMLS). A retrospective study was conducted of gait laboratory records and video assessments for a consecutive sample of children with CP aged 4 to 18 years who were managed by multilevel surgery. FMS ratings and Gross Motor Function Classification System (GMFCS) levels were recorded preoperatively and at regular postoperative time points. The sample comprised 66 children (32 females, 34 males) with spastic diplegia, GMFCS Levels I (n=18), II (n=24), and III (n=24). The mean age at surgery was 10 years (SD 2y 6mo, range 6–16y). For each FMS distance (5, 50, and 500m) odds ratios showed significant deterioration in mobility at 3 and 6 months postoperatively. Mobility then improved to baseline levels by 12 months and improved further by 24 months postoperatively. GMFCS level remained stable throughout most of the postoperative period for children classified as GMFCS Level III preoperatively but not for children classified as Levels I or II. The FMS was found to be a clinically feasible tool for quantifying change after SEMLS in children with CP.

Reliability of the Functional Mobility Scale for Children with Cerebral Palsy.

ABSTRACT This study examined inter-rater reliability of the Functional Mobility Scale (FMS) for children with cerebral palsy (CP) and the presence of rater bias. A consecutive sample of 118 children with CP, 2–18 years old (mean 10.3 years, SD 3.6), was recruited from a hospital setting. Children were classified using the gross motor function classification system (GMFCS) with 13 in Level I, 49 in Level II, 44 in Level III, and 12 in Level IV. Each child was independently scored on the FMS by two raters. Raters were randomly assigned from a sample of 44 orthopaedic surgeons, hospital-based physiotherapists, and community-based physiotherapists. Quadratic weighted kappa coefficients for mobility ratings varied from 0.86 to 0.92 for the three distances, indicating substantial chance corrected agreement. Levels of agreement were similar when administering the scale in person and by telephone, suggesting that the FMS can be administered by either method. There was a tendency for surgeons to rate mobility higher than physiotherapists, however, only one of the comparisons was statistically significant. The FMS is a reliable tool that can be used by clinicians to assess mobility in children with CP.

A Systematic Review of Common Physiotherapy Interventions in School-Aged Children with Cerebral Palsy

ABSTRACT This systematic review focused on the common conventional physiotherapy interventions used with children with cerebral palsy (CP), aged 4 to 18 years, and critically appraised the recent evidence of each of these interventions using the Oxford Centre for Evidence-Based Medicine Levels of Evidence. The search strategy yielded 34 articles after inclusion and exclusion criteria were applied. The investigated physiotherapy interventions included strength and functional training, weight-supported treadmill training (WBSTT), and neurodevelopmental treatment (NDT). A category of treatment dosage was also included. Strength training was the most studied intervention with significant improvements found in the strength of selected muscle groups using dynamometry, with fewer studies showing significant improvement in function. Functional training showed improvements in gross motor function, endurance, and temperospatial measures, such as gait speed and stride length. Nonsignificant trends of improvement on the Gross Motor Function Measure (GMFM) and gait velocity were found for WBSTT by a few studies with low levels of evidence (case series). Of three studies that evaluated NDT, one high-level evidence study, i.e., randomized controlled trial (RCT) found significant improvements on the GMFM. All studies reviewing treatment dosage had high levels of evidence (RCTs), yet found no significant differences for different intensities of treatment. These results indicate that the levels of evidence for physiotherapy interventions, particularly strengthening and to a lesser extent functional training, in school-aged children with CP has improved; however, further high-level evidence is needed for other interventions.

Lengthening and transfer of hamstrings for a flexion deformity of the knee in children with bilateral cerebral palsy: TECHNIQUE AND PRELIMINARY RESULTS

Between July 2000 and April 2004, 19 patients with bilateral spastic cerebral palsy who required an assistive device to walk had combined lengthening-transfer of the medial hamstrings as part of multilevel surgery. A standardised physical examination, measurement of the Functional Mobility Scale score and video or instrumented gait analysis were performed pre- and post-operatively. Static parameters (popliteal angle, flexion deformity of the knee) and sagittal knee kinematic parameters (knee flexion at initial contact, minimum knee flexion during stance, mean knee flexion during stance) were recorded. The mean length of follow-up was 25 months (14 to 45). Statistically significant improvements in static and dynamic outcome parameters were found, corresponding to improvements in gait and functional mobility as determined by the Functional Mobility Scale. Mild hyperextension of the knee during gait developed in two patients and was controlled by adjustment of their ankle-foot orthosis. Residual flexion deformity > 10 degrees occurred in both knees of one patient and was treated by anterior distal femoral physeal stapling. Two children also showed an improvement of one level in the Gross Motor Function Classification System.

Does parent report measure performance? A study of the construct validity of the Functional Mobility Scale

Aim  Parental report is often relied on to measure performance of activities in children with cerebral palsy (CP). This study examined whether the Functional Mobility Scale (FMS) accurately reflects performance of mobility in children with CP.

Interventions in Pediatric Chronic Fatigue Syndrome/Myalgic Encephalomyelitis: A Systematic Review

PURPOSE A range of interventions have been used for the management of Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) in children and adolescents. Currently, debate exists as to the effectiveness of these different management strategies. The objective of this review was to synthesize and critically appraise the literature on interventions for pediatric CFS/ME. METHOD CINAHL, PsycINFO and Medline databases were searched to retrieve relevant studies of intervention outcomes in children and/or adolescents diagnosed with CFS/ME. Two reviewers independently selected articles and appraised the quality on the basis of predefined criteria. RESULTS A total of 24 articles based on 21 studies met the inclusion criteria. Methodological design and quality were variable. The majority assessed behavioral interventions (10 multidisciplinary rehabilitation; 9 psychological interventions; 1 exercise intervention; 1 immunological intervention). There was marked heterogeneity in participant and intervention characteristics, and outcome measures used across studies. The strongest evidence was for Cognitive Behavioral Therapy (CBT)-based interventions, with weaker evidence for multidisciplinary rehabilitation. Limited information exists on the maintenance of intervention effects. CONCLUSIONS Evidence for the effectiveness of interventions for children and adolescents with CFS/ME is still emerging. Methodological inadequacies and inconsistent approaches limit interpretation of findings. There is some evidence that children and adolescents with CFS/ME benefit from particular interventions; however, there remain gaps in the current evidence base.

Reliable Classification of Functional Profiles and Movement Disorders of Children with Cerebral Palsy

ABSTRACT Objective: To examine the inter-rater reliability of the Communication Function Classification System (CFCS), Bimanual Fine Motor Function (BFMF), Surveillance of Cerebral Palsy in Europe (SCPE) classification tree, and Gross Motor Function Classification System (GMFCS) in children with cerebral palsy (CP) and periventricular white matter injury (PWMI) aged 4–11 years. Method: Twenty children were assessed by two raters using the four tools, in addition parents undertook ratings on the Manual Ability Classification System (MACS). Kappa statistics were used to calculate the level of agreement between raters’ classifications. Results: Participants comprised 12 males and 8 females with CP and PWMI, mean age 8 years 1 month (standard deviation 2 years 3 months). Inter-rater reliability across the four tools was 0.98 (CFCS, BFMF, and GMFCS) and 0.84 (SCPE). Implications: These findings suggest that these four tools are reasonably robust to inter-rater variability supporting their routine use along with the MACS in clinical and research applications.

Video gait analysis for ambulatory children with cerebral palsy: Why, when, where and how!

PURPOSE This paper outlines the application of video gait analysis (VGA) for children with cerebral palsy (CP) when full instrumented three dimensional gait analysis (3DGA) is either not indicated or not available. SCOPE Gait analysis is an important part of the assessment of ambulant children with CP for diagnosing gait deviations and for evaluating change. Many regard 3DGA as the most informative method of assessing gait, however, it is not always accessible, practical, or feasible and the detail obtained is not always indicated. VGA in conjunction with other carefully selected outcome measures can provide a comprehensive gait assessment in situations where 3DGA is not available or not indicated. Indications for VGA use include: documenting change in gait pattern over time, frequent monitoring in the rehabilitation phase following treatments and interventions (including surgery, spasticity management, serial casting and intensive therapy), monitoring orthotic changes, and for very young children and those with behavioural/cognitive issues that preclude them from cooperating with a 3DGA. Simple and inexpensive VGA systems can be set up in most settings. In an effort to make the process more objective and reliable a number of observational gait scales have been developed. Of these the Edinburgh Gait Score (EGS) has the strongest psychometric properties and is the most comprehensive by including both the coronal and the sagittal planes. CONCLUSION While 3DGA remains an important part of complex clinical decision-making, there is also an increasingly important role for VGA. Guidelines need to be developed for its use within the field of gait analysis.
