Multi-adjustable chairs for children with disabilities

The International Classification of Functioning, Disability and Health provides a Model for Adaptive Seating Interventions for Children with Cerebral Palsy

Children with severe types of cerebral palsy use adaptive seating systems to encourage function and assist in delaying the development of deformity. These systems are often assessed for and provided by occupational therapists. However, there has been no unifying policy or theoretical basis on which these systems are provided and research evidence is lacking, with studies tending to be small and non-controlled.

The International Classification of Functioning, Disability and Health (World Health Organisation 2001a,b) aims to establish a common language for clinical practice as well as research, while bringing together the opposing social and medical models of health care delivery. This paper suggests that the ICF model is an ideal theoretical basis for adaptive seating system assessment and provision, given that these systems often conflict between the medical model of reducing or delaying impairment of body functions and structures and the social model of children and families accessing life and environmental situations through mobility and seating equipment.

The paper considers all the domains of the ICF with regard to the current literature. It concludes that using the model in the context of providing adaptive seating gives occupational therapists both a powerful tool for communicating with children and families as well as managers and a basis for evaluating practice.

Clinical tools that measure sitting posture, seated postural control or functional abilities in children with motor impairments: a systematic review

OBJECTIVE

To identify and critically appraise clinical measurement tools used to assess sitting posture, seated postural control or functional abilities for children with motor impairment who are candidates for seating interventions.

DATA SOURCES

Searches were run in 15 electronic databases along with hand searching. The search included articles published in English to December 2011.

REVIEW METHODS

Key terms included: posture, sitting, sitting posture, seated posture, seated postural control, sitting position, seating, wheelchair(s), outcome and assess(ment). The PRISMA statement was followed with inclusion criteria set a priori. Two reviewers independently screened titles, reviewed abstracts and identified full-text articles that met criteria. Data extraction included tool description and clinical utility. Two quality-rating scales were used to evaluate conduct of the studies and psychometric properties of the tools.

RESULTS

Of the 497 titles found in the search, 29 full-text articles met the inclusion criteria and 19 tools were identified. Tools represented all components of the International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY), with emphasis on body structure and function and activity components. Evidence supporting reliability and validity varied, with small sample sizes influencing quality ratings. Evidence of the tools' reliability was more prevalent than evidence of the tools' validity. Only four tools reported on responsiveness, an important consideration for evaluating change. Little information on clinical utility was provided.

CONCLUSION

Although a number of tools are available, evidence supporting their use for seating interventions is limited, as is the evidence supporting the strength of their measurement properties. Few tools address participation, environmental factors or the child's and family's perspective.

Buggy-to-wheelchair progression for children with cerebral palsy: Parents’ and therapists’ opinions

Some children with cerebral palsy (CP) are transported in buggies until they master the skills of ambulation. Many never learn to walk and progress from a buggy to a wheelchair as a means of maximizing their independence and improving their motor and functional skills. Therapists and parents often hold conflicting views as to why a child may not be progressed to a wheelchair from a buggy.

A study was undertaken to explore the opinions of health professionals and parents concerning this problem. A questionnaire for each cohort (therapists n=17; parents n=28) was constructed containing 10 identical but general questions. Results obtained were analysed individually for each cohort and then compared to see if there was any concordance between them. Both groups believed the main factors preventing change were: transport problems making wheelchair travel difficult; inadequate housing; poorer manoeuvrability of the wheelchair compared with the buggy; and a lack of information about progressing to a wheelchair. Statistical analysis showed no correlation between how parents and therapists responded. A multilingual handbook for therapists and parents needs to be produced detailing the pros and cons of buggy-to-wheelchair progression.

A comparison between parents?? and therapists?? views of their child??s individual seating systems

Children with cerebral palsy are often prescribed adaptive seating systems for use in their wheelchairs for the purposes of improving posture and to help prevent the development of long-term deformity. However, clinical experience indicates that parents and the therapists who advocate the use of these systems do not always agree about the wheelchairs. This study discusses the development of questionnaires for both parents and therapists to measure differences in their opinions about the wheelchairs. The questions were developed through clinical experience, validation was through interviews to discuss topics important to the participants, and repeated application of the questionnaire ensured consistency. The reliability of the questions appears satisfactory and the interview responses demonstrate that the questions selected are important to both groups of stakeholders. However, it was found that parental concerns over their children's seating systems concentrated on functional and day-to-day management issues, whereas therapist concerns focused on technical issues and postural management. Both groups of stakeholders agreed that the questionnaires would be a useful precursor to attending a seating clinic appointment, as it could aid communication between the parent and provider and improve the efficiency and satisfaction of such an appointment. It appears the questionnaire has potential as an outcome measurement tool.
