Evidence for 24-hour posture management: A scoping review

Introduction:

People with complex physical disabilities unable to change their position independently are at risk of developing postural deformities and secondary complications. 24-hour posture management is needed to protect body structure. With inconsistencies in current service provision, this research aimed to scope the evidence for a 24-hour posture management approach.

Method:

A scoping review was conducted using four health and social science databases. Inclusion and exclusion criteria were applied; further papers were included through citation chaining.

Results:

The evidence for 24-hour posture management was often low quality due to the complications of completing robust research studies in this complex specialty. However, many professionals in the field agree that a 24-hour approach to postural care is essential.

Conclusion:

There is a need for clear national policy and guidance relating to postural care and scope for development of dedicated posture management services. Current NHS service provision is variable and inconsistent. Lack of postural care is a safeguarding and human rights issue. Specialist training and research in postural care within the Occupational Therapy profession is required to raise awareness of the role Occupational Therapists can play in preventing postural deformities and other secondary complications through providing good postural care.

Current clinical practice in 24-hour postural management and the impact on carers and service users with severe neurodisability

Introduction

The clinical benefits of 24-hour postural management are widely recognised by occupational therapists, but little is known about its impact on service users and carers or whether clinical practice is consistent across regions. The aim of this research was to investigate the use of 24-hour postural management by occupational therapists and to explore its impact on service users with neurodisability and their carers.

Methods

Quantitative and qualitative methods were employed in two phases: (a) online survey with 96 occupational therapists across one UK region, with data analysed by descriptive statistics and correlations; (b) focus groups with service users and/or carers ( n = 9), with data analysed by thematic analysis.

Results

Findings showed moderate positive correlation between frequency of use and (a) all key intervention skills and (b) knowledge of night-time positioning ( p < 0.001). Moderate positive correlations were found between level of training and (a) assessment skills and (b) knowledge of night-time positioning ( p < 0.001). The overarching theme from focus groups was ‘reliance on individualised equipment’, with overwhelming frustration from lack of support, loss of identity, equipment cost, insufficient focus on preventative strategies and accessibility issues.

Conclusion

A clinical practice guideline, including training, is crucial to direct practice. Providers must engage with service users and carers to address their frustrations.

Wheelchair and seating assistive technology provision: a gateway to freedom

Aim: The meaning of wheelchair and seating assistive technology and the impact inappropriate provision has on people's lives from a service user's perspective within an Irish context is highlighted. There is a dearth in evidence examining the process of wheelchair and seating provision and the interconnectedness between satisfaction, performance and participation from an equality and human rights perspective. The purpose if the study is to investigate wheelchair service users' perspectives of wheelchair and seating provision in Ireland.Method: This is a mixed-methods study with an exploratory sequential design that includes two phases. During phase one, wheelchair service users were invited to take part in qualitative in-depth semi-structured interviews, which were thematically analysed and formed part of a larger ethnographic study involving multiple stakeholders in sustainable wheelchair and seating provision strategy development. In phase two, an online Survey Monkey questionnaire was distributed to obtain a wider overview of wheelchair service provision from a wheelchair service users perspective. Data obtained from the closed questions and content analysis for open comments was analysed descriptively for this phase.Results: Eight wheelchair service users agreed to participate in the interviews and 273 responded to the online survey. Thematic analysis and questionnaire frequency and content analysis revealed the vital meaning of wheelchair and seating assistive technology provision. However, bottlenecks within the system affect daily living, with qualitative data highlighting the obstruction to experiences of independent living from initial appointment to wheelchair breakdowns during daily life.Conclusion: Appropriate wheelchair and seating assistive technology provision is a basic human right, supported by the essential and embodied nature of the wheelchair as demonstrated through the wheelchair service users' perspective throughout this study. These findings highlight the impact of ad-hoc services on individual freedoms and how the overall pace of the system affects a person's ability to organise their time as an equal member of the community across the lifespan. A national review of wheelchair and seating assistive technology provision services is called for, giving consideration to access to services, assessment and delivery, follow up and management, education and training.IMPLICATIONS FOR REHABILITATIONWheelchair and seating assistive technology provision as a basic human right is misunderstood.Appropriate wheelchair and seating assistive technology provision should be provided to meet this primary need as a pre-requisite for survival.Every aspect of the wheelchair and seating provision process impacts on occupational performance, equality of opportunity and community mobility. Wheelchair and seating assistive technology professionals and providers have a responsibility to review their practice and service provision systems.

Evaluation of the multidimensional effects of adaptive seating interventions for young children with non-ambulatory cerebral palsy

PURPOSE

To investigate the short-term effectiveness of the first adaptive seating system received by children with non-ambulatory cerebral palsy (CP) who are classified as level IV or V according to the Gross Motor Function Classification System.

MATERIALS AND METHODS

A trained clinical assessor examined 20 children with non-ambulatory CP (mean age: 4.5 years) for their trunk control ability in static, active, and reactive tasks using the Segmental Assessment of Trunk Control. Their primary caregivers were also interviewed about their child's activity and participation using the Paediatric Evaluation of Disability Inventory Computer - Adaptive Test in daily activity and social/cognitive domains and Family Impact of Assistive Technology Scale for Adaptive Seating in child and family functioning domains. Data for each measure were collected 3 times: at baseline (pre-intervention) and then 6 weeks and 3 months after children received their first adaptive seating system.

RESULTS AND CONCLUSION

The static and active trunk control scores between baseline and 6 weeks, and baseline and 3 months significantly improved. Daily activity scaled scores significantly improved between baseline and 3 months, and 6 weeks and 3 months. Significant, large gains in child and family functioning overall were detected between baseline and 6 weeks, and baseline and 3 months. These findings provide emerging evidence of multidimensional effects associated with the introduction of a first adaptive seating system into the lives of young children with non-ambulatory CPIMPLICATIONS FOR REHABILITATIONThe introduction of an adaptive seating system into the wheelchair of children with non-ambulatory cerebral palsy may be associated with short-term gains in body function, activities, participation and aspects of the child's environment.

Postural asymmetry in non-ambulant adults with cerebral palsy: a scoping review

PURPOSE

Non-ambulant adults with cerebral palsy are vulnerable to development of postural asymmetry and associated complications. The primary aim of this scoping review was to identify postural deformities in non-ambulant adults with cerebral palsy.

MATERIALS AND METHODS

Comprehensive searches were undertaken in EMBASE, CINAHL, AMED, Cochrane, Psych INFO, and Joanna Briggs (1986-Jan 2017), supplemented by hand searching. Two reviewers independently extracted data using a customised tool focusing on study design, participant characteristics, postural descriptors, measurement tools, and interventions.

RESULTS

From 2546 potential records, 17 studies were included. Variability in populations, reporting methodology, and measurement systems was evident. Data suggest more than 30% of this population have hip migration percentage in excess of 30%, more than 75% experience "scoliosis", and more than 40% demonstrate pelvic obliquity. Estimates ranged from 14% to 100% hip and 32% to 87% knee contracture incidence. Conservative interventions were infrequently and poorly described.

CONCLUSION

Many non-ambulant adults with cerebral palsy experience postural asymmetry associated with windswept hips, scoliosis, pelvic obliquity, and limb contracture. Options for non-radiographic monitoring of postural asymmetry should be identified, and conservative interventions formally were evaluated in this population. Implications for rehabilitation The common postural asymmetries of windswept hips, scoliosis, pelvic obliquity, and limb contracture require standardised clinical measurement. Radiography is most commonly used to monitor postural asymmetry in this population, but standardised positioning is not applied and may not be feasible indicating a need for alternate methods and rigorous documentation. The Posture and Postural Ability Scale may be considered for use in the management of body shape in adults with CP.

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.

A systematic review of interventions for children with cerebral palsy: state of the evidence

AIM

The aim of this study was to describe systematically the best available intervention evidence for children with cerebral palsy (CP).

METHOD

This study was a systematic review of systematic reviews. The following databases were searched: CINAHL, Cochrane Library, DARE, EMBASE, Google Scholar MEDLINE, OTSeeker, PEDro, PsycBITE, PsycINFO, and speechBITE. Two independent reviewers determined whether studies met the inclusion criteria. These were that (1) the study was a systematic review or the next best available; (2) it was a medical/allied health intervention; and (3) that more than 25% of participants were children with CP. Interventions were coded using the Oxford Levels of Evidence; GRADE; Evidence Alert Traffic Light; and the International Classification of Function, Disability and Health.

RESULTS

Overall, 166 articles met the inclusion criteria (74% systematic reviews) across 64 discrete interventions seeking 131 outcomes. Of the outcomes assessed, 16% (21 out of 131) were graded 'do it' (green go); 58% (76 out of 131) 'probably do it' (yellow measure); 20% (26 out of 131) 'probably do not do it' (yellow measure); and 6% (8 out of 131) 'do not do it' (red stop). Green interventions included anticonvulsants, bimanual training, botulinum toxin, bisphosphonates, casting, constraint-induced movement therapy, context-focused therapy, diazepam, fitness training, goal-directed training, hip surveillance, home programmes, occupational therapy after botulinum toxin, pressure care, and selective dorsal rhizotomy. Most (70%) evidence for intervention was lower level (yellow) while 6% was ineffective (red).

INTERPRETATION

Evidence supports 15 green light interventions. All yellow light interventions should be accompanied by a sensitive outcome measure to monitor progress and red light interventions should be discontinued since alternatives exist.

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.

Patient and equipment profile for wheelchair seating clinic provision

PURPOSE

To characterise the provision of wheelchair seating both pre- and post-clinical intervention and compare and contrast the two largest diagnostic groups.

METHOD

The case notes of those attending a wheelchair seating clinic for adults over a defined period were reviewed retrospectively. A classification system was devised that delineates between the complexity and type of equipment to gain a better understanding of provision.

RESULTS

146 patients were included; mean age 45 years (SD 16); 53.4% male. The two most prevalent primary medical diagnoses were cerebral palsy (CP) and multiple sclerosis (MS); 48.6% and 20.5%, respectively. The MS group, in comparison to the CP group, were significantly more likely to be older, new to seating provision, have been seen more recently, have a powered wheelchair, self-propel their manual wheelchair, have low rather than high complexity equipment and have their equipment changed following assessment.

CONCLUSIONS

The equipment classification system will allow results from different studies to be readily compared. The results for those with CP and MS reflect the respective stable and progressive nature of these conditions. Referrals for those with MS should be prioritised. Wheelchair seating users with MS should be reassessed ∼18 months after provision.

IMPLICATIONS FOR REHABILITATION

A detailed classification of wheelchair seating equipment based on a recognised standard vocabulary, such as the one proposed, is required to gain a better understanding of provision. Wheelchair seating equipment budget and staffing levels should reflect the diagnostic make up of a service's patient population. Referrals for people with MS should be prioritised as their current wheelchair seating provision is more likely not to be meeting their needs. People with MS should have a clinical review 18 months after wheelchair seating provision.

Validation of the relation between the type and amount of seating support provided and Level of Sitting Scale (LSS) scores for children with neuromotor disorders

OBJECTIVES

To assess the construct validity of the Level of Sitting Scale (LSS) by examining the relationship between LSS scores and the type and amount of seating supports.

METHODS

Secondary analysis of the data for 114 children ≤18 years, with neuromotor disorders who participated in a responsiveness study of the Seated Postural Control Measure.

RESULTS

A significant inverse relationship (Spearman rho = -0.42, p < 0.05) was found between LSS scores and amount of seating support provided. Statistically significant differences were also revealed between LSS levels of sitting ability (p < 0.004) and pelvic, thigh, trunk and head seating components and type of seating system, using Kruskal-Wallis test.

CONCLUSION

This study provides evidence of construct validity for the LSS in use as a discriminative measure of sitting ability in children with neuromotor disorders. Further validation is justified. Clinically intuitive associations between sitting ability and seating interventions were confirmed.

Botulinum toxin assessment, intervention and aftercare for paediatric and adult drooling: international consensus statement

Many individuals with neurological problems or anatomical abnormalities of the jaw, lips or oral cavity may drool, which can impact on health and quality of life. A thorough evaluation of the patient's history, examination of the oral region by a speech pathologist and, in individuals over 3 years, a dental examination is warranted. Questionnaires with established validity such as the Drooling Impact Scale are useful assessment tools. A hierarchical approach to treatment is taken from least invasive therapies, such as speech pathology, to more invasive, such as injection of botulinum neurotoxin type-A (BoNT-A) into the salivary glands (parotid and submandibular). The wishes of the individual and their carer are crucial considerations in determining the suitability of the intervention for the patient. In the presence of dysphagia and cerebral palsy (CP), careful assessment is required prior to the injection of BoNT-A. Favourable responses to intervention include a reduction in the secretion of saliva and in drooling, as well as psychosocial improvements. BoNT-A is usually well tolerated, although potential side effects should be discussed with the patient and carer.

Night-Time Positioning for Children with Postural Needs: What is the Evidence to Inform Best Practice?

This paper presents the findings of a review of the literature concerning the assessment and provision of night-time positioning for children with postural needs. The aim of the review was to source and evaluate the evidence available for the efficacy of current treatments and to establish best practice.

There is a small but growing body of evidence demonstrating that night-time positioning is beneficial to children with postural needs when used within a child and family centred 24-hour postural management programme. Children and families need timely assessment and provision of equipment, together with appropriate training and support to learn to use night-time positioning equipment effectively.

Occupational therapists have a distinct role in the assessment and provision of night-time positioning equipment and need to be both skilled in assessment and knowledgeable about postural management and the equipment available. This review of literature suggests that further research is required to strengthen the evidence for the efficacy of night-time positioning equipment and to guide therapists in best practice.

Longitudinal study evaluating a seating system using a sacral pad and kneeblock for children with cerebral palsy

PURPOSE

Adaptive seating systems using sacral pads and kneeblocks are commonly used throughout the UK with children with complex motor disorders to improve their posture and stability in sitting. We sought to evaluate how effective these systems are for a group of children with cerebral palsy.

METHOD

A six-visit trial was performed to examine whether this combination controls pelvic and hip positioning. Twenty-three children with cerebral palsy aged 7 - 14 years participated (11 females and 12 males). The kneeblocks (active intervention) were removed for a period in the middle of the trial. Force exerted through the kneeblock, pressure exerted on the sacral pad and postural alignment was measured for change.

RESULTS

Statistically significant differences before and after kneeblock removal were found for force at the kneeblock, but no difference was found in pressure at the sacral pad. No statistically significant correlations between force and pressure or posture were found.

CONCLUSION

The results indicate that seating systems using a sacral pad and kneeblock may not improve overall posture but may improve hip position in children with cerebral palsy.

Management of seating posture of children with cerebral palsy by using thoracic-lumbar-sacral orthosis with non-rigid SIDO frame

PURPOSE

To investigate the effects of a special seating device: Thoracic-lumbar-sacral orthosis with non-rigid SIDO frame (TLSO-SIDO) in non-ambulant children with cerebral palsy.

METHOD

A prospective study with matched pairs (the same subject pre- and post-intervention) was carried out. A comparison of the lateral view of thoracic-lumbar spine X-ray before and after TLSO-SIDO application was made. The assessment of changes in daily activities, posture was recorded by questionnaires. A total of 47 children with cerebral palsy at a mean age of 53.2 months +/- 30.1 SD were involved in the study; 15 (35.71%) of the 42 children showed significant problems in feeding at the beginning of the study period, they were identified as a special subgroup with feeding difficulties.

RESULTS

The mean pre-TLSO-SIDO thoracic kyphosis was 53.7 +/- 16.2 in Cobb angle, while the post-TLSO-SIDO thoracic kyphosis was 47.2 +/- 12.1. The lumbar lordosis was 21.3 +/- 13 and in the TLSO-SIDO 17.8 +/- 11.9. The majority of the children have shown improvement in the feeding items and in posture (trunk, head and extremities). The overall satisfaction of the parents with the TLSO-SIDO was very good, namely 3.972 +/- 0.796 on the 5-point analogue scale. We did not find a direct correlation with the improvement in the separate items and the overall satisfaction.

CONCLUSION

It is extremely difficult to measure the effect of the postural management on the development of children with cerebral palsy. According to the results of the study, regular application of the TLSO-SIDO in children with spastic cerebral palsy had a beneficial effect on feeding problems and on posture.

The JCM Moonlite Sleep System: Assisting in the provision of 24-hour postural support

Children and adults with mobility problems often suffer with contraction of unused muscles, which can consequently pose a risk to joint stability. Both contraction and joint instability can be extremely painful, leading to among other issues, poor quality of sleep. Although seating provision attempts to maintain appropriate posture during the day, suitable equipment provision must also be considered for the night. Sleep systems aim to provide appropriate support, promote postural symmetry and increase quality of sleep.

This article discusses the Moonlite Sleep System, manufactured by JCM. It describes the features and benefits of the system and summarizes client feedback to date.

Therapist's influence on the design of Invacare's Flo-Tech Solution Xtra

The trend for inclusive design appears to becoming stronger, and an area that clinicians are urged to participate in. Combining clinical and technical expertise can often be a demanding challenge and this paper looks to show the results of how a modular postural cushion was designed and evaluated by Invacare Ltd. The Flo-Tech Solution Xtra modular system was conceived through joint collaboration between manufacturer and therapists following discussion and demand from NHS wheelchair services (WCS) in the UK. Concept, rationale and design of the cushion are discussed from a clinical perspective, which underpins the manufacturing process from conception through to the finished product. The seating system was designed to address the postural requirements primarily of the neurological population and consequently the cushion underwent clinical trial at the Royal Hospital of Neuro-Disability, Putney, London.

Seven subjects were identified as suitable for the evaluation by the postural team at Putney and three were trialed independently by Invacare Ltd. The main focus of this study was identifying and meeting the individual's therapeutic aims of posture and pressure through using the Solution Xtra. Even though the study size was small and the results subjective in nature, there was an overall favourable outcome of using the modular system as a seating intervention, and it was also rated highly by the clinicians involved.
