Effectiveness of physical therapy interventions for children with cerebral palsy: A systematic review

BackgroundTo assess the effectiveness of physical therapy (PT) interventions on functioning in children with cerebral palsy (CP).MethodsA search was made in Medline, Cinahl, PEDro and the Cochrane library for the period 1990 to February 2007. Only randomized controlled trials (RCTs) on PT interventions in children with diagnosed CP were included. Two reviewers independently assessed the methodological quality and extracted the data. The outcomes measured in the trials were classified using the International Classification of Functioning, Disability and Health (ICF).ResultsTwenty-two trials were identified. Eight intervention categories were distinguished. Four trials were of high methodological quality. Moderate evidence of effectiveness was established for two intervention categories: effectiveness of upper extremity treatments on attained goals and active supination, and of prehensile hand treatment and neurodevelopmental therapy (NDT) or NDT twice a week on developmental status, and of constraint-induced therapy on amount and quality of hand use. Moderate evidence of ineffectiveness was found of strength training on walking speed and stride length. Conflicting evidence was found for strength training on gross motor function. For the other intervention categories the evidence was limited due to low methodological quality and the statistically insignificant results of the studies.ConclusionDue to limitations in methodological quality and variations in population, interventions and outcomes, mostly limited evidence on the effectiveness of most PT interventions is available through RCTs. Moderate evidence was found for some effectiveness of upper extremity training. Well-designed trials are needed especially for focused PT interventions.

The HTA Core Model: A novel method for producing and reporting health technology assessments

OBJECTIVES The aim of this study was to develop and test a generic framework to enable international collaboration for producing and sharing results of health technology assessments (HTAs). METHODS Ten international teams constructed the HTA Core Model, dividing information contained in a comprehensive HTA into standardized pieces, the assessment elements. Each element contains a generic issue that is translated into practical research questions while performing an assessment. Elements were described in detail in element cards. Two pilot assessments, designated as Core HTAs were also produced. The Model and Core HTAs were both validated. Guidance on the use of the HTA Core Model was compiled into a Handbook. RESULTS The HTA Core Model considers health technologies through nine domains. Two applications of the Model were developed, one for medical and surgical interventions and another for diagnostic technologies. Two Core HTAs were produced in parallel with developing the model, providing the first real-life testing of the Model and input for further development. The results of formal validation and public feedback were primarily positive. Development needs were also identified and considered. An online Handbook is available. CONCLUSIONS The HTA Core Model is a novel approach to HTA. It enables effective international production and sharing of HTA results in a structured format. The face validity of the Model was confirmed during the project, but further testing and refining are needed to ensure optimal usefulness and user-friendliness. Core HTAs are intended to serve as a basis for local HTA reports. Core HTAs do not contain recommendations on technology use.

Effectiveness of upper and lower limb casting and orthoses in children with cerebral palsy: an overview of review articles.

Autti-Rämö I, Suoranta J, Anttila H, Malmivaara A, Mäkelä M: Effectiveness of upper and lower limb casting and orthoses in children with cerebral palsy: An overview of review articles. Am J Phys Med Rehabil 2006;85:89–103. The objective of this overview is to summarize from systematic reviews the evidence on the effectiveness of using upper and lower limb casting or orthoses in children with cerebral palsy. We used computerized bibliographic databases to search for systematic reviews without any language restrictions. Identification, selection, quality assessment, and data extraction were performed independently by two investigators. Of the 40 identified reviews, 23 were selected for closer consideration, and five reviews met the inclusion criteria. The quality of existing systematic reviews and original studies included in our reviews varied widely. The following evidence was found: (1) casting of lower limbs has a short-term effect on passive range of movement; (2) orthoses that restrict ankle plantar flexion have a favorable effect on an equinus walk, but the long-term clinical significance is unclear; (3) evidence on managing upper limb problems with casting or splinting in children with cerebral palsy is inconclusive. Our conclusion is that there is a paucity of evidence from primary studies on the use of orthoses in children with cerebral palsy. More original, well-designed research is needed.

Effectiveness of Physiotherapy and Conductive Education Interventions in Children with Cerebral Palsy : A Focused Review

Anttila H, Suoranta J, Malmivaara A, Mäkelä M, Autti-Rämö I: Effectiveness of physiotherapy and conductive education interventions in children with cerebral palsy: a focused review. Am J Phys Med Rehabil 2008;87:478–501. We conducted a criteria-based appraisal of systematic reviews on the effectiveness of physiotherapy and conductive education interventions in children with cerebral palsy (CP). Computerized bibliographic databases were searched without language restriction up to August 2007. Reviews on trials and descriptive studies were included. Two reviewers independently identified, selected, and assessed the quality of the reviews using the criteria from the Overview Quality Assessment Questionnaire complemented with decision rules. Twenty-one reviews were included, six of which were of high methodological quality. Altogether, the reviews included 23 randomized controlled trials and 104 observational studies on children with CP. The high-quality reviews found some evidence supporting strength training, constraint-induced movement therapy, or hippotherapy, and insufficient evidence on comprehensive physiotherapy and occupational therapy interventions. Conclusions in the other reviews should be interpreted cautiously, although, because of the poor quality of the primary studies, most reviews drew no conclusions on the effectiveness of the reviewed interventions. Reviews on complex interventions in heterogeneous populations should use rigorous methods and report them adequately, closely following the Quality of Reporting of Meta-Analyses recommendations.

Quality of Reporting of Randomized, Controlled Trials in Cerebral Palsy

OBJECTIVES. In conducting reviews on the effectiveness of physiotherapy interventions on children with cerebral palsy, the assessment of trials can be hampered by problems in reporting. Therefore, we set out to evaluate trial reporting by using the Consolidated Standards of Reporting Trials (CONSORT) statement recommendations. METHODS. Randomized, controlled trials published in 1990 or later were identified in literature searches for reviews on the effectiveness of physiotherapy interventions on children with cerebral palsy. Two independent reviewers evaluated the trial reporting by using a modified 33-item Consolidated Standards of Reporting Trials checklist. RESULTS. We identified 15 randomized, controlled trials. Almost half (48%) of the applicable items were reported adequately. Inadequate reporting was found in the following items: outcome measures, sample-size determination, details of the sequence generation, allocation concealment and implementation of the randomization, success of assessor blinding, recruitment and follow-up dates, intention-to-treat analysis, precision of the effect size, co-interventions, and adverse events. CONCLUSIONS. Only a small number of sufficiently reported trials were found. Because nearly all items had been described in at least 1 article, high-quality reporting seems feasible. Assessment of trials depends on appropriate reporting, and poor reporting jeopardizes judgments on the clinical implications. Authors of randomized, controlled trials are encouraged to follow the Consolidated Standards of Reporting Trials criteria. There is a clear need to improve the quality of reporting of trials in this field.

Lymphoedema therapy in breast cancer patients - a systematic review on effectiveness and a survey of current practices and costs in Finland

Background. This study systematically evaluates the effects and harms of physiotherapy methods and explores current treatment practices and costs in relation to lymphoedema in breast cancer patients in Finland. Material and methods. A systematic review of randomized controlled trials (RCTs) on physiotherapy interventions for breast cancer patients with lymphoedema. A postal survey to lymph therapists, a telephone and register survey for therapy costs. Results. We identified 14 RCTs, of which two had moderate and the others high risk of bias. There was moderate evidence that compression bandages decreased lymphoedema, and that pneumatic pumps had no effect on lymphoedema. In Finland lymph therapy practice is a combination of manual lymph drainage (MLD), compression bandages, therapeutic exercises and guidance for self-treatment, with an annual average cost of EUR 799 per patient. Conclusions. Compression bandages are likely to reduce upper limb lymphoedema in breast cancer patients. Evidence on other physiotherapy methods and their combinations is limited due to the poor quality of the trials. No evidence was found on any outcomes other than upper limb volume. We call for well-designed trials with patient-related outcomes on the effectiveness of MLD, guidance and therapeutic exercises.

Testing the HTA Core Model: Experiences from two pilot projects

OBJECTIVES The aim of this study was to analyze and describe process and outcomes of two pilot assessments based on the HTA Core Model, discuss the applicability of the model, and explore areas of development. METHODS Data were gathered from HTA Core Model and pilot Core HTA documents, their validation feedback, questionnaires to investigators, meeting minutes, emails, and discussions in the coordinating team meetings in the Finnish Office for Health Technology Assessment (FINOHTA). RESULTS The elementary structure of the HTA Core Model proved useful in preparing HTAs. Clear scoping and good coordination in timing and distribution of work would probably help improve applicability and avoid duplication of work. CONCLUSIONS The HTA Core Model can be developed into a platform that enables and encourages true HTA collaboration in terms of distribution of work and maximum utilization of a common pool of structured HTA information for national HTA reports.

Ethical Issues of Obesity Surgery—a Health Technology Assessment

New surgical technologies may challenge societal values, and their adoption may lead to ethical challenges. Despite proven cost-effectiveness, obesity (bariatric) surgery and its public funding have been questioned on ethical arguments relating to, for example, the self-inflicted or non-disease nature of obesity. Our aim was to analyze the ethical issues relevant to bariatric surgery. A comprehensive health technology assessment was conducted on bariatric surgery for morbid obesity using the EUnetHTA method, including a fully integrated ethical analysis. The ethical arguments suggesting that obesity should not be surgically treated because it is self-inflicted were rejected. Medicalization of obesity may have both positive and negative effects that impact the various stakeholders differently, thus being difficult to balance. Informing bariatric surgery patients and actively supporting their autonomy is exceptionally important, as the benefits and harms of both obesity and bariatric surgery are complex, and the outcome depends on how well the patient understands and adheres to the life-long changes in eating habits required. Justice considerations are important in organizing surgical treatment of obesity, as the obese are discriminated against in many ways and obesity is more common in socioeconomically disadvantaged populations who might have problems of access to treatments. Obesity should be treated like other diseases in health care, and obesity surgery rationed like other cost-effective treatments. Positive actions to ensure patient autonomy and just access to surgical treatments may be warranted.
