Development of an evidence-based clinical algorithm for practice in hypotonia assessment: a proposal.

BACKGROUND: Assessing muscle tone in children is essential during the neurological assessment and is often essential in ensuring a more accurate diagnosis for appropriate management. While there have been advances in child neurology, there remains much contention around the subjectivity of the clinical assessment of hypotonia, which is often the first step in the diagnostic process. OBJECTIVE: In response to this challenge, the objective of the study is to develop and validate a prototype of a decision making process in the form of a clinical algorithm that will guide clinicians during this assessment process. METHODS: Design research within a pragmatic stance will be employed in this study. Multi-phase stages of assessment, prototyping and evaluation will occur. These will include processes that include a systematic review, processes of reflection and action as well as validation methods. Given the mixed methods nature of this study, use of NVIVO or ATLAS-ti will be used in the analysis of qualitative data and SPSS for quantitative data. RESULTS: Initial results from the systematic review revealed a paucity of scientific literature that documented the objective assessment of hypotonia in children. The review identified the need for more studies with greater methodological rigor in order to determine best practice with respect to the methods used in the assessment of low muscle tone in the paediatric population. CONCLUSIONS: It is envisaged that this proposal will contribute to a more accurate clinical diagnosis of children with low muscle tone in the absence of a gold standard. We anticipate that the use of this tool will ultimately assist clinicians towards moving to evidenced based practice whilst upholding best practice in the care of children with hypotonia.

Accessibility for persons with mobility impairments within an informal trading site: A case study on the markets of Warwick, South Africa.

BACKGROUND: There are a number of informal trading sites across cities in sub-Saharan Africa, of which the markets of Warwick is one example. Since the informal economy is an important contributor to a city's economy as well as a source of employment, it is important for these sites to be accessible for all persons. Whilst the South African government has put structures in place to identify and remove environmental barriers in order to meet the individual needs of persons with mobility impairments and improve their quality of life, persons with mobility impairments still face barriers and restricting environments that prevent them from participating in society and its social and economic activities. OBJECTIVES: This case study aimed at exploring accessibility within the markets of Warwick for persons with mobility impairments by an ergonomic assessment, augmented by voices of participants within the market. METHOD: A qualitative, instrumental, single case study design was utilised with purposive sampling of the markets of Warwick as the study setting. Multiple sources of data were gathered, such as semi-structured interviews, direct observations of an environmental survey supported by photographs, and the authors' review of relevant documents. Transcriptions were analysed using NVivo 10 software programme with inductive coding. RESULTS: Whilst policies have been in place since 1996 to adjust infrastructure, the markets of Warwick still remain inaccessible to persons with mobility impairments and do not meet the standardised infrastructural design. CONCLUSION: The findings of this study may offer a significant understanding of the complexity of accessibility within an informal trading site and create an awareness of the limitations this has for persons with mobility impairments. Additionally, these findings may assist in effecting a positive change in terms of the infrastructure of the Markets and in continuous advocating for the rights of persons with all disabilities.

Consensus on hypotonia via Delphi process.

OBJECTIVES: To generate consensus on the assessment of hypotonia in the pediatric population, more specifically with respect to the clinical characteristics and first line tests and methods to be used to assess these characteristics. METHODS: Consensus methodology was used. A sample of experts was recruited based on specific inclusion criteria. A two-round Delphi process was conducted electronically, which was based on a prior literature appraisal and survey amongst a cohort of clinicians. An a priori threshold margin error of 70 ± 5 % was pre-determined, with Cronbach's α measuring the level of internal consistency. RESULTS: The 2-round iteration was useful in establishing consensus on clinical characteristics and tests /methods in the assessment of low muscle tone in the pediatric population (2-5 y age band). Twenty-four clinical characteristics, organized into 11 clusters were determined as relevant for inclusion. For each characteristic, one test (as a first line assessment method) had been identified with consensus after two rounds. Additionally, consensus on the importance of collateral sources was determined. The ranking order of importance of characteristics however revealed variations. CONCLUSIONS: The results of this study have displayed that Delphi, if executed with available guidelines, may be a useful technique in moving towards consensus on issues that may be contentious and have assisted in providing initial data to move towards consensus on the assessment of hypotonia in children.
