A quantitative analysis of optimum design for rigid ankle foot orthoses: The effect of thickness and reinforcement design on stiffness

BACKGROUND

An ankle foot orthosis (AFO) which is prescribed to be rigid should only deform a small amount to achieve its clinical goals. Material thickness and the design of reinforcing features can significantly affect AFO rigidity, but their selection remains based on anecdotal evidence.

OBJECTIVES

To quantify the effect of these parameters on AFO stiffness and to set the basis for quantitative guidelines for the design optimisation of rigid AFOs.

STUDY DESIGN

Experimental and computational study.

METHODS

A polypropylene AFO was produced according to UK standard practice and its stiffness was experimentally measured for 30Nm of dorsiflexion. Its geometry and mechanical characteristics were utilised to create a finite element (FE) model of a typical AFO prescribed to be rigid. Following validation, the model was used to quantify the effect of material thickness and reinforcement design (i.e., reinforcement placement, length) on stiffness. A final set of AFO samples was produced to experimentally confirm key findings.

RESULTS AND CONCLUSIONS

For a specific AFO geometry and loading magnitude, there is a thickness threshold below which the AFO cannot effectively resist flexion and buckles. FE modelling showed that stiffness is maximised when reinforcements are placed at the anterior-most position possible. This key finding was also experimentally confirmed. The stiffness of an AFO reinforced according to standard practice with lateral and medial ribbing was 4.4 ± 0.1 Nm/degree. Instructing the orthotic technician to move the ribbings anteriorly increased stiffness by 22%. Further stiffening is achieved by ensuring the reinforcements extend from the footplate to at least two-thirds of the AFO's total height.

Exploration of the representation of the allied health professions in senior leadership positions in the UK National Health Service

BACKGROUND

Allied health professionals (AHPs) are an important group within the National Health Service (NHS) in the UK and make up a large portion of the workforce. Investment in AHP leadership is believed to lead to improvements in patient care, resource use, collaboration and innovation. This study aims to assess the current state of AHP strategic leadership within the NHS.

METHODS

A freedom of information (FOI) request was sent to all NHS Trusts and health boards (HBs) within the UK NHS. The questions focused on the AHP workforce, with a particular interest in the chief AHPs (or equivalent roles) working in an NHS setting. Analysis of the FOI used a range of descriptive statistics.

RESULTS

Of the 217 Trusts/HBs contacted, responses were received from 160 (74%). The majority (81%) reported that they employed a Chief AHP or equivalent role, with only 14% of these having a position on the Trust/HB executive board. There were 50 different job titles reported as the titles for the chief AHP or equivalent roles: with director of AHPs (18.6%), lead AHP (13.9%) and chief AHP (11.6%) being the most reported titles. The results identified an inequity of representation of AHP professions within senior AHP leadership; with most of these roles (70%) held by physiotherapists and occupational therapists.

CONCLUSION

Changes in AHP strategic leadership are needed to address the inequities identified in this study. Addressing these issues is required to enable inclusive leadership, which is crucial to improve the contribution of AHPs to healthcare.

The national profile of the prosthetic and orthotic workforce in the UK: Sociodemographics and employment characteristics

BACKGROUND

Prosthetists and orthotists (POs) are essential members of the health care workforce and one of the United Kingdom's (UK's) allied health professions. There is a paucity of information on their demographics, which is essential for the development of the profession. To fill this void, this study has attempted to comprehensively explore the sociodemographics and work-related characteristics of the entire workforce.

METHODS

Data were collected in 2022 through multiple sources, including surveys of POs, private companies employing POs, and freedom of information requests to National Health Service Trusts/Health Boards and higher education institutes offering programs leading to registration as a prosthetist/orthotist.

RESULTS

The workforce survey had 641 respondents (74% response rate). The estimated national ratio of POs per million population was 13, with all bar of the 12 regions below the World Health Organization minimum recommendation of 15 POs per million population. Most of the survey respondents were female (47.6%) and younger than male respondents, were British (75.8%), and in the White ethnic group (74.3%). Most of them were employed by private companies (59.9% vs. 31.4% employed by the National Health Service) and had clinical duties (94%), permanent contracts (90%), worked full-time (75%), and treated a wide range of clinical conditions.

CONCLUSIONS

The national UK prosthetist and orthotist ratio falls below the recommended international standards. The versatility and broad skill set of POs highlight their crucial role in multidisciplinary teams. Establishing a centralized prosthetist and orthotist workforce database system is recommended for data-driven strategic planning.

The UK prosthetic and orthotic workforce: current status and implications for the future

BACKGROUND

Prosthetists and orthotists (POs) are the smallest of the 14 allied health profession (AHP) workforces within NHS England. Obtaining data on the workforce has always been challenging due to this information being held across different organisations. An understanding of the prosthetic and orthotic (P&O) workforce is essential to ensure that it is adequately equipped to meet the evolving needs of users of P&O services. The study aims to estimate the size and composition, for the first time, of the UK P&O workforce and P&O service provision.

METHODS

To gather the required information, two surveys (one for the UK P&O workforce and one for UK P&O private company) and two freedom of information (FOI) requests [one for all NHS Trusts and Health Boards (HB) in the UK and one for the higher education institutes in the UK offering programmes leading to registration as a PO were developed and distributed from September to December 2022.

RESULTS

The P&O workforce survey received a 74% response rate (863 POs) and 25 private companies reported employing one or more P&O staffing groups. From the FOI requests, 181 of a potential 194 Trusts/Health Boards and all four higher education institutions responded. The study indicated a total of 1766 people in the UK P&O workforce, with orthotists and orthotic technicians representing the largest percentage of the workforce at 32% and 30%, respectively. A greater percentage of prosthetists (65%) and orthotists (57%) were employed by private companies compared to the NHS. Only 34% of POs stated that they "definitely" planned to remain in the workforce for the next 5 years. The current UK PO employment levels are 142 to 477 short of the World Health Organisation's (WHO) recommendation.

CONCLUSIONS

The low job satisfaction amongst many POs and the projected increase in the number of people who will require prosthetic and/or orthotic care in the UK are challenges for future UK P&O services. Strategies are required to create a sustainable and resilient workforce that can meet the needs of a changing healthcare landscape.

Non-Invasive Assessment of Back Surface Topography: Technologies, Techniques and Clinical Utility

(1) Background: Frequent exposure to ionising radiation is often used to determine the diagnosis of adolescent idiopathic scoliosis (AIS), a lateral curvature of the spine in those aged between 10 and 18 years, and a treatment plan according to Cobb angle. This narrative review outlines the clinical utility of surface topography (ST), a radiation-free imaging modality. (2) Methods: Publicly available databases were searched to yield literature related to ST. Identified articles were classified based on the equipment used and in order of how it was developed, i.e., historical, recent developments, and state-of-the-art developments. (3) Conclusions: ST is a reliable cost-effective non-invasive technique that provides an alternative to radiation-based imaging to aid with the diagnosis and potential screening of AIS. Several scanning methods are available, which allows ST to be used in several clinical environments. Limitations of inter-reliability and differences of apparatus resulting in variations of data have been noted through this narrative review.

The challenge of service planning and development without adequate data: The case for orthotic services

The UK National Health Service (NHS) employs a group of 14 separate allied health professions. Prosthetics and orthotics are the smallest of these professions. Although small, orthotics is integral to many clinical care pathways and has shown to provide an essential impact on a range of clinical conditions in the health service priority lists. Previous reports acknowledged the lack of data on the UK prosthetic and orthotic workforce, appointment outcomes and cost and the service users accessing such services and thus the challenges that it poses for effective service delivery. There is still a paucity of relevant data or initiatives to support the service provision. The work within this paper has taken the first step to address this gap, presenting a summary of the information relating to appointments and costs, and provides a discussion on the implications of variations across the NHS orthotic services within England in terms of spend, staffing and skill mix for orthotic services and service users and the need for further data on service users and the UK prosthetic and orthotic workforce.

Do UK Allied Health Professionals (AHPs) have sufficient guidelines and training to provide telehealth patient consultations?

OBJECTIVES

The COVID-19 pandemic caused a rapid shift to remote consultations. United Kingdom (UK) NHS Allied Health Professional (AHP) services may have been unprepared for telehealth implementation. This study explored these services' organisational readiness regarding telehealth guidelines implementation and staff training.

METHODS

A cross-sectional online survey exploring available telehealth guidelines and staff training was distributed among UK AHPs and AHP service managers between May and June 2021.

RESULTS

658 participants answered the survey (119 managers and 539 clinicians). Most services, in which telehealth was in place, had implemented telehealth guidelines (clinicians, 64%; managers, 82%), with most guidelines produced by the NHS staff who use them for their consultations. Most clinicians reported that guidelines had ambiguous areas (e.g., regarding protection from litigation and dealing with emergencies), whereas most managers reported the opposite opinion. Guidelines most frequently reported on appropriate telehealth technology and environment for staff and patients, while recommended consultation length and how to conduct telehealth with certain population groups were least reported. Clinicians lacked training in most telehealth aspects, while managers reported that staff training focused on telehealth software and hardware. For both clinicians and managers, training is needed on how to deal with emergencies during telehealth.

CONCLUSIONS

UK NHS AHP services are not fully equipped with clear and comprehensive guidelines and the skills to deliver telehealth. Vulnerable people are excluded from current guidelines, which may widen health inequalities and hinder the success of the NHS digital transformation. The absence of national guidelines highlights the need for uniform AHP telehealth guidelines.

Prescription practices for rigid ankle-foot orthoses among UK orthotists

OBJECTIVE

The purpose of this study was to investigate rigid ankle-foot orthosis (AFO) prescription practices for adult men among UK orthotists.

DESIGN

A cross-sectional study using a survey was distributed online to UK orthotists by the British Association of Prosthetists and Orthotists to its members and through social media and orthotic networks. The survey was completed between November 1, 2020, and November 29, 2020.

MAIN OUTCOME MEASURES

Descriptive statistics of survey results include information related to the material used, the thickness of the material, positive cast rectification, AFO reinforcement, footplate design, padding, strapping system, and height of AFO.

RESULTS

One hundred participants completed the survey, which equates to a response rate of 30.5% of the British Association of Prosthetists and Orthotists members targeted. A clear consensus emerged on the design of a bespoke rigid AFO for the hypothetical patient in this study, which is detailed as follows: 1) 4.5 mm copolymer polypropylene, 2) no additional reinforcement, 3) full-length footplate with mediolateral trimlines terminating behind the metatarsal heads, 4) 3-point correction with parallel sides, 5) padded VELCRO straps with D-rings at the calf and heel, 6) no forefoot or other additional strapping, 7) 3-mm PORON (international Ltd) padding at the malleoli, and 8) AFO height that finishes 2 cm below the fibular head.

CONCLUSIONS

This study has highlighted a consensus on AFO prescription/design among UK orthotists surveyed, based on the hypothetical patient described in this study.

The potential impact of allied health professional telehealth consultations on health inequities and the burden of treatment

BACKGROUND

The COVID-19 pandemic resulted in a rapid shift to remote consultations. The study aimed to explore the prevalence of telehealth consultations amongst allied health professional (AHP) services in the UK National Health Service (NHS), and the potential impact on health inequities and burden of treatment for patients.

METHODS

Cross-sectional online survey. Participants were practising UK registered AHP and/or AHP service manager in an NHS/social care/local authority service. Data was collected between May - June 2021.

RESULTS

658 participants took part in this study, including 119 AHP service managers, managing a total of 168 AHP services, and 539 clinicians. 87.4% of clinicians and 89.4% of services represented were using telehealth consultations as a method of delivering healthcare, the majority reported their services were planning to continue using telehealth post COVID-19 restrictions. Participants reported a lack of technological skills for patients as the most prevalent barrier affecting the patient's ability to conduct a telehealth consultation, followed by a lack of technology for patients. These were also reported as the biggest disadvantages of telehealth for patients. The majority of clinicians reported a reduction in the cost of parking/transport to attend hospital appointments as a patient benefit of telehealth consultations. Reported benefits for clinicians included saving travel time/costs and allowing flexible working, while benefits to the AHP service included patient flexibility in how their appointments are conducted and reducing the potential exposure of staff to communicable diseases.

CONCLUSIONS

The current large-scale implementation of telehealth in NHS AHP services may increase disparities in health care access for vulnerable populations with limited digital literacy or access. Consequently, there is a danger that telehealth will be considered inappropriate and thus, underutilised, negating the potential benefits of sustainability, patient empowerment and the reduction in the burden of treatment.

Exploration of implementation, financial and technical considerations within allied health professional (AHP) telehealth consultation guidance: a scoping review including UK AHP professional bodies' guidance

OBJECTIVES

The COVID-19 pandemic has resulted in a shift to remote consultations, but telehealth consultation guidelines are lacking or inconsistent. Therefore, a scoping review was performed to chart the information in the articles exploring telehealth for the UK allied health professionals (AHPs) and compare them with the UK AHP professional bodies' guidelines.

DESIGN

Scoping review following Aksey and O' Malley methodological framework.

DATA SOURCES

CINHAL and MEDLINE were searched from inception to March 2021 using terms related to 'telehealth', 'guidelines' and 'AHPs'. Additionally, the UK AHP professional bodies were contacted requesting their guidelines.

STUDY SELECTION

Articles exploring telehealth for patient consultations, written in English and published in peer-reviewed journal or guidelines available from UK AHP professional bodies/their websites were considered eligible for review.

DATA EXTRACTION

One reviewer extracted data concerning three overarching domains: implementation, financial and technological considerations.

RESULTS

2632 articles were identified through database searches with 21 articles eligible for review. Eight guidelines were obtained from the UK AHP professional bodies with a total of 29 included articles/guidelines. Most articles were published in the last two years; there was variety in telehealth terminology, and most were developed for occupational therapists, physiotherapists and speech and language therapists. Information was lacking about the assessment of telehealth use and effectiveness, barriers and limitations, the logistical management, the family's and caregiver's roles and the costs. There was lack of clarity on the AHPs' registration requirements, costs and coverage, and legal aspects.

CONCLUSION

This study identified gaps in current guidelines, which showed similarities as well as discrepancies with the guidance for non-AHP healthcare professionals and revealed that the existing guidelines do not adequately support AHPs delivering telehealth consultations. Future research and collaborative work across AHP groups and the world's leading health institutions are suggested to establish common guidelines that will improve AHP telehealth services.

The emergence of telehealth in orthotic services across the United Kingdom

COVID-19 has impacted the National Health Service provision, creating urgency for departments to adapt and adopt new ways of delivering healthcare. The purpose of this service evaluation was to determine the emergence of telehealth in orthotic services across the UK in response to COVID-19. A survey exploring telehealth use was distributed online to orthotists approximately 6 months after the first peak of COVID-19 in the UK. It gathered information on telehealth prevalence, allocated appointment length and waiting times, clinician access to technology and clinicians' opinions on the efficacy of telehealth. The survey received 77 responses with over 90% of respondents reporting using telehealth. Most reported that they expected telehealth to remain part of the service, post COVID-19. Thematic analysis produced two main themes: the impact of COVID-19 and challenges still to overcome. Findings suggest that the pandemic has resulted in a backlog of patients waiting for an orthotic appointment, with services currently understaffed and lacking resources. For telehealth to be effective orthotists must have access to appropriate technology and training on how to use telehealth platforms, be provided with appropriate guidance on which patients are appropriate for telehealth consultations and given appropriate appointment times to enable safe and effective care.

How has the COVID-19 pandemic affected orthotic services in the United Kingdom?

BACKGROUND

COVID-19 has had a significant impact on the National Health Service in the United Kingdom (UK).

OBJECTIVE

This study aimed to determine the impact of COVID-19 on orthotic services in the United Kingdom.

STUDY DESIGN

Cross sectional survey.

METHODS

An online survey was distributed to UK orthotists approximately 6 months after the first peak of COVID-19. Descriptive statistics of results related to appointment waiting times, disruption of services, introduction of telehealth appointments, and clinicians' opinions on the impact of COVID-19 was completed.

RESULTS

Seventy-seven orthotists completed the survey, with many reporting that their service was closed or open only to inpatients/urgent patients at some point during the pandemic. There were substantial variation in appointment waiting times, time allocated per appointment, and increases in lead times for orthotic products across services. Over 90% reported using telehealth appointments. Results were comparable with previous research showing long appointment waiting times and indicated that the pandemic has added to this issue.

CONCLUSIONS

The pandemic has had a significant impact on orthotic services with face-to-face appointments largely reserved for urgent patients and inpatients, and services going through stages of closing and reopening, alongside the introduction of telehealth to ensure less urgent patients could continue to access orthotic care. Future service evaluation studies are required to further assess how orthotic services have been affected by the pandemic and the effectiveness of recovery plans.

Ankle Foot Orthoses: Standardisation of terminology

The term Ankle Foot Orthosis (AFO) has been standardised and defined by the International Organization for Standardisation which offers general terms for external orthoses, describing terms relating to external orthoses including the abbreviation AFO. These standards relate to functional deficiencies including a description of the person to be treated with an orthosis, clinical objectives of treatment, and functional requirements of the orthosis and offers categorisation and description of external orthoses and orthotic components using the aforementioned standards. However, it is important to point out that these definitions and standardisations only apply to the term "AFO". Yet the terms used to describe the different types of AFOs have not been standardised and defined.

Does user perception affect adherence when wearing biomechanically optimised ankle foot orthosis - footwear combinations: A pilot study

STUDY DESIGN

Pilot study.

BACKGROUND

Ankle foot orthoses (AFOs) and footwear combination (FC) is a commonly prescribed medical device given to children with cerebral palsy (CP) in an attempt to improve their gait. Biomechanically optimising the AFO-FC often requires large adaptations to the sole of the user's footwear. There is currently a dearth of literature regarding the user's perception of wearing biomechanically optimised AFOs and adapted footwear and whether their perception affects their adherence to orthotic treatment.

OBJECTIVE

This study aimed to investigate perception and adherence to wearing an AFO and FC the participants were asked to wear as part of their orthotic prescription. In particular, whether the visibly modified footwear affected the user's adherence to the orthotic treatment.

METHODS

Questionnaire devised for the purpose of this study.

RESULTS

All five participants responded to the questionnaire; reporting a high number of positive responses in relation to function, including; an improvement in the way they walked, improved balance and fewer falls. Conversely, there was a high level of negative responses regarding aesthetics, with all participants reporting they did not like the cosmesis of their AFO-FCs. They were conscious that the modification to their footwear was noticeable and therefore different from their peers, yet they adhered to the treatment and in some cases increased the wearing time.

CONCLUSIONS

This pilot set of questions indicated that cosmesis is an important factor for children who wear AFOs and adapted footwear. It can be concluded that the impact of the adapted AFO-FC on the participants' function outweighed their opinion on the cosmesis of the device.

CLINICAL RELEVANCE

It is vital to understand how orthotic prescriptions affect user adherence. Orthotic prescriptions which are not utilised by the user result in a failed treatment intervention, regardless of the scientific application underpinning them.

The effect of tuning ankle foot orthoses-footwear combinations on gait kinematics of children with cerebral palsy: A case series

STUDY DESIGN

Case series.

BACKGROUND

AFOs are a commonly prescribed medical device given to children with cerebral palsy (CP) in an attempt to improve their gait. The current literature is equivocal on the effects AFOs have on the gait of children with CP. The vast majority of AFOs issued are not subject to AFO-FC tuning. There are emerging studies investigating the effects tuning AFO-FCs has on the gait of children with CP. However, the research is limited, and there is a lack of quantitative data.

OBJECTIVE

To compare the kinematics of tuned versus non-tuned gait in children with CP.

METHODS

Gait analysis assessment of five children aged between 7-11 years with a diagnosis of CP (one hemiplegic and four diplegic participants, two female, three male, with a Gross Motor Functional Classification System (GMFCS) of 2) at a Gait Analysis Laboratory.

RESULTS

In comparison to barefoot and non-tuned gait, walking with a tuned AFO-FC produced improvements in several key gait parameters. Including hip flexion and extension, posterior pelvic tilt and knee extension. Results also indicated that the type of gait pattern demonstrated by the participant affected the outcomes of tuning.

CONCLUSIONS

Tuning the AFO-FC of children with CP has the potential to improve hip function, pelvic function, knee extension in stance phase and knee flexion during swing phase and that a non-tuned AFO-FC can potentially decrease hip function, posterior pelvic tilt and increase knee extension.

CLINICAL RELEVANCE

Whilst AFO-FC tuning has been recommended for routine clinical practice, there still remains a paucity of research on the kinematic effects of using a tuned AFO-FC compared to a non-tuned. This paper provides a comparison of kinematics on children with CP, during barefoot, non-tuned and tuned AFO-FC walking with a view to inform clinical practice.

Cross-sectional survey of orthotic service provision in the UK: does where you live affect the service you receive?

OBJECTIVE

To investigate the quantity and quality of orthotic service provision within the UK.

DESIGN

Cross-sectional survey obtained through freedom of information request in 2017.

SETTING

National Health Service (NHS) Trusts/Health Boards (HBs) across the UK.

MAIN OUTCOME MEASURES

Descriptive statistics of survey results, including information related to finance, volume of appointments, patients and orthotic products, waiting times, staffing, complaints, outcome measures and key performance indicators.

RESULTS

Responses were received from 61% (119/196) of contacted Trusts/HBs; 86% response rate from Scotland (12/14) and Wales (6/7), 60% (3/5) from Northern Ireland and 58% (98/170) from England. An inhouse service was provided by 32% (35/110) of responses and 68% (74/110) were funded by a block contract. Long waiting times for appointments and lead times for footwear/orthoses, and large variations in patient entitlements for orthotic products across Trusts/HBs were evident. Variations in the length of appointment times were also evident between regions of the UK and between contracted and inhouse services, with all appointment times relatively short. There was evidence of improvements in service provision; ability for direct general practitioner referral and orthotic services included within multidisciplinary clinics. However, this was not found in all Trusts/HBs.

CONCLUSIONS

The aim to provide a complete UK picture of orthotic service provision was hindered by the low response rate and limited information provided in some responses, with greater ability of Trusts/HBs to answer questions related to quantity of service than those that reflect quality. However, results highlight the large discrepancies in service provision between Trusts/HBs, the gaps in data capture and the need for the UK NHS to establish appropriate processes to record the quantity and quality of orthotic service provision. In addition to standardising appointment times across the NHS, guidelines on product entitlements for patients and their lead times should be prescribed to promote equity.

A scoping literature review of studies assessing effectiveness and cost-effectiveness of prosthetic and orthotic interventions

Purpose: Approximately 1.5% of the world's population (∼100 million people) need a prosthesis/orthosis. The objective of the study was to establish an overview of the literature that has examined prosthetic and orthotic interventions with a view to inform policy development.Methods: Fourteen databases were searched from 1995-2015. Studies reporting primary research on the effectiveness or cost-effectiveness of prosthetic and orthotic interventions were examined. Metadata and information on study characteristics were extracted from the included studies.Results: The searches resulted in a total of 28,958 articles, a focus on studies with the words "randomized" OR "randomized" OR "cost" OR "economic" in their citation reduced this total to 2644. Research has predominantly been conducted in Australia, Canada, Germany, Netherlands, UK and USA. A total of 346 randomized controlled trials were identified, with only four randomized controlled trials examining prosthetic interventions. The majority of research examined lower limb orthoses in the adult population and used a wide range of outcome measures.Conclusions: While various international organizations have highlighted the value of providing prosthetic and orthotic services, both to the user and society as a whole, the availability of scientific research to inform policy is limited. Future structured evaluation of prosthetic and orthotic interventions/services is warranted to inform future policy developments.Implications for rehabilitationResearch into prosthetic and orthotic interventions has grown substantially in the last 20 years, with most of this research conducted in a small number of countries and focusing on the use of lower limb orthotics in adult populations.Research to date has utilized an extensive range of outcome measures, the development of agreed standardized sets of outcomes would allow comparison and combination of results in future research.This study highlights the need for further research in this area, especially studies which examine the cost-effectiveness of prosthetic and orthotic provision.

Do research papers provide enough information on design and material used in ankle foot orthoses for children with cerebral palsy? A systematic review

OBJECTIVES

The purpose of this article is to determine how many of the current peer-reviewed studies of ankle foot or-thoses (AFOs) on children with cerebral palsy (CP) have included adequate details of the design and material of the AFO, to enable the study to be reproduced and outcomes clearly understood.

METHODS

A thorough search of studies published in English was conducted in March 2015, with no restriction on dates, within all major databases using relevant phrases. These searches were then supplemented by tracking all key references from the appropriate articles identified.

STUDY SELECTION

The inclusion criteria were as follows: (1) population - children with CP; (2) intervention - AFOs; and (3) outcome measure. One reviewer extracted data regarding the characteristics of the included studies, with the extracted data checked for accuracy and completeness by a second reviewer. None of the studies reviewed gave adequate details of the AFOs. Only 3.6% (n = 2) of papers tested the stiffness. Many studies (54.5%) did not describe the material used nor the material thickness (72.7 %). None of them gave any clinical justification for the chosen design of AFO.

CONCLUSIONS

There is a clear paucity of detail regarding the design and material used in AFOs on studies involving children with CP. Such a lack of detail has the potential to affect the validity of the reported outcomes, the ability to reproduce the studies and may misinform clinical practice.

Ankle foot orthosis-footwear combination tuning: an investigation into common clinical practice in the United Kingdom

BACKGROUND

Ankle foot orthoses are used to treat a wide variety of gait pathologies. Ankle foot orthosis-footwear combination tuning should be routine clinical practice when prescribing an ankle foot orthosis. Current research suggests that failure to tune ankle foot orthosis-footwear combinations can lead to immediate detrimental effect on function, and in the longer term, it may actually contribute to deterioration.

OBJECTIVES

The purpose of this preliminary study was to identify the current level of knowledge clinicians have in the United Kingdom regarding ankle foot orthosis-footwear combination tuning and to investigate common clinical practice regarding ankle foot orthosis-footwear combination tuning among UK orthotists.

STUDY DESIGN

Cross-sectional survey.

METHODS

A prospective study employing a multi-item questionnaire was sent out to registered orthotists and uploaded on to the official website of British Association of Prosthetists and Orthotists to be accessed by their members.

RESULTS

A total of 41 completed questionnaires were received. The results demonstrate that only 50% of participants use ankle foot orthosis-footwear combination tuning as standard clinical practice. The most prevalent factors preventing participants from carrying out ankle foot orthosis-footwear combination tuning are a lack of access to three-dimensional gait analysis equipment (37%) and a lack of time available in their clinics (27%).

CLINICAL RELEVANCE

Although, ankle foot orthosis-footwear combination tuning has been identified as an essential aspect of the prescription of ankle foot orthoses, the results of this study show a lack of understanding of the key principles behind ankle foot orthosis-footwear combination tuning.

The effect of tuning ankle foot orthoses-footwear combination on the gait parameters of children with cerebral palsy

BACKGROUND

There are a wide variety of ankle foot orthoses used in clinical practice which are characterised by their design, the material used and the stiffness of that material. Changing any of these three components will alter the effect of the ankle foot orthosis on gait.

OBJECTIVES

The purpose of this article is to provide an overview on the available research on ankle foot orthosis-footwear combination tuning on the gait characteristics of children with cerebral palsy through a structured review.

STUDY DESIGN

Literature review.

METHODS

A thorough search of previous studies published in English was conducted within all major databases using relevant phrases without any limits for the dates. These searches were then supplemented by tracking all key references from the appropriate articles identified including hand searching of published books where relevant.

RESULTS

To date, there are 947 papers in the literature pertaining to the study of ankle foot orthosis. Of these, 153 investigated the use of ankle foot orthosis for children with cerebral palsy. All the studies included in this review were of a within-subjects design and the evidence levels were generally low.

CONCLUSIONS

The overall results suggested that ankle foot orthosis-footwear combination tuning has the potential to improve the kinematics and kinetics of gait in children with cerebral palsy. However, the review highlights a lack of well-designed and adequately powered studies. Clinical relevance While the research described in this article indicates an improvement in the gait of children with cerebral palsy following tuning of their ankle foot orthosis-footwear combination, there is still a paucity of research with quantitative data on the effects of kinematics and kinetics of ankle foot orthosis-footwear combination tuning, comparing untuned ankle foot orthosis-footwear combinations with tuned ankle foot orthosis-footwear combination. Furthermore, current research does not identify the effect of tuning on energy efficiency.
