A scoping review of digital fabrication techniques applied to prosthetics and orthotics: Part 1 of 2-Prosthetics.

BACKGROUND: Traditionally, the manufacture of prostheses is time-consuming and labor-intensive. One possible route to improving access and quality of these devices is the digitalizing of the fabrication process, which may reduce the burden of manual labor and bring the potential for automation that could help unblock access to assistive technologies globally. OBJECTIVES: To identify where there are gaps in the literature that are creating barriers to decision-making on either appropriate uptake by clinical teams or on the needed next steps in research that mean these technologies can continue on a pathway to maturity. STUDY DESIGN: Scoping literature review. METHODS: A comprehensive search was completed in the following databases: Allied and Complementary Medicine Database, MEDLINE, Embase, Global Health Archive, CINAHL Plus, Cochrane Library, Web of Science, Association for Computing Machinery, Institute of Electrical and Electronics Engineers, and Engineering Village, resulting in 3487 articles to be screened. RESULTS: After screening, 130 lower limb prosthetic articles and 117 upper limb prosthetic articles were included in this review. Multiple limitations in the literature were identified, particularly a lack of long-term, larger-scale studies; research into the training requirements for these technologies and the necessary rectification processes; and a high range of variance of production workflows and materials which makes drawing conclusions difficult. CONCLUSIONS: These limitations create a barrier to adequate evidence-based decision-making for clinicians, technology developers, and wider policymakers. Increased collaboration between academia, industry, and clinical teams across more of the pathway to market for new technologies could be a route to addressing these gaps.

Exploring the patient experience and perspectives of taking part in outcome measurement during lower limb prosthetic rehabilitation: a qualitative study.

PURPOSE: Outcome measurement provides clinicians, services and funders with useful information. However, little is known about the experience of participating in outcome measurement during lower limb prosthetic rehabilitation from the patient's perspective. MATERIALS AND METHODS: Thirty-two participants who underwent lower limb amputation within 5 years, and had experience of taking part in outcome measurement during prosthetic rehabilitation, were recruited from UK limb fitting centers and social media. Data were collected using focus groups and interviews and analysed using reflexive thematic analysis. RESULTS: Four themes were identified. (1) How does participating in outcome measurement make me feel? (2) Do the outcome measures used in routine clinical care capture an accurate picture of my recovery? (3) Who is outcome measurement for? and (4) are prosthetic services measuring what is meaningful? These themes suggest outcome measurement is not a neutral activity for patients following lower limb amputation. CONCLUSIONS: Harnessing the positive impacts of measuring outcomes could be used for motivation, to support adjustment and recovery, to improve communication and to support shared decision-making. This could make outcome measurement more meaningful and patient-centered. However, there may be potential for patients to respond negatively to outcome measures and clinicians should consider their impact on psychosocial factors.

Outcome measurement in prosthetic rehabilitation can provide clinicians, service providers and funders with important information.Adopting a patient-centred approach could make the process more meaningful and therefore beneficial for patients themselves.Measuring what is important to patients by considering a holistic approach beyond physical domains may make outcome measurement more meaningful.Patient centred approaches may include talking to patients about outcome measurement, using it to support motivation, goal setting and decision-making, as well as exploring outcome ranges to account for, or even capture variability.However, the potential for negative responses should not be overlooked, and clinicians should consider the psychosocial impact of outcome measurement on this patient group, especially when using performance-based measures.

Exploring meaningful outcome domains of recovery following lower limb amputation and prosthetic rehabilitation: the patient's perspective.

PURPOSE: There is currently no consensus regarding what outcome domains to measure following lower limb prosthetic rehabilitation. Prosthetic users have a unique insight into important outcome domains, little is currently known about their critical viewpoint. MATERIALS AND METHODS: A total of 37 participants who underwent lower limb amputation in the last five years were recruited from UK limb fitting centres and social media. Data were collected using focus groups and interviews and analysed using reflexive thematic analysis. RESULTS: Five themes were identified. 1) The ability to participate in important activities, 2) how participants were able to undertake these activities, i.e., independently, with ease, safely and with minimal equipment. 3) A comfortable, easy-to-use prosthesis, 4) the importance of managing pain and finally, 5) adjusting and accepting their new normal. These five themes, or outcome domains, did not exist in isolation, but appeared to interact with each other, contributing to, or inhibiting the participant's holistic sense of recovery. CONCLUSIONS: Understanding important outcome domains that define what recovery means to people following amputation can help to inform domain consensus, as well as direct the focus of rehabilitation. Domain consensus would guide the selection of measurement tools that evaluate prosthetic interventions in a meaningful way.IMPLICATIONS FOR REHABILITATIONThere is currently no consensus around which outcome domains should be measured following prosthetic rehabilitation.Outcome domains of importance from a patient's perspective focus on participation in important activities, prosthesis comfort, pain management, and acceptance of their new normal.Identifying these domains can help direct the focus of rehabilitation as well as inform outcome measurement practice.The interrelated nature of these domains suggests the need for a physical and psychosocial multi-domain approach to outcome measurement in prosthetic rehabilitation, with patient priorities at its centre.

Footwear characteristics and foot problems in community dwelling people with stroke: a cross-sectional observational study.

PURPOSE: To explore footwear characteristics and foot problems in community dwelling people with stroke as most research to date focused on the general elderly population. METHODS: Thirty people with mild to moderate stroke (nine men, mean age 68, mean time since onset 67 months) attended a single session to assess footwear and foot problems using established podiatry foot (wear) and ankle assessments. RESULTS: Most participants wore slippers indoors (n = 17, 57%) and walking shoes outdoors (n = 11, 37%). Over half wore unsupportive ill-fitting shoes indoors and 47% of outdoor shoes fitted badly. All participants had foot problems (mean 6.5 (3.1), 95% CI: 5.4-7.7), including impaired single limb heel raise (93%), reduced range of movement (77%), sensation (47%), and muscle strength (43%). Many had foot-pain, hallux valgus (both 50%), or swollen feet (40%). Foot problems were associated with reduced balance confidence, activity, and community participation (all p < 0.05). A greater proportion of fallers (13/16) than non-fallers (4/14) reported foot problems (p = 0.029). CONCLUSIONS: Many community-dwelling people with stroke wore poorly fitting shoes; all had foot problems. Foot problems were linked to reduced mobility. Finding more effective pathways to support people with stroke to select supportive, well-fitting indoor and outdoor footwear is indicated.Implications for rehabilitationPeople with stroke often wear unsupportive ill-fitting shoes and experience foot problems.Assessment of foot problems and footwear advice should be considered during stroke rehabilitation particularly when interventions target fall prevention or improvements in balance and mobility.Information on appropriate footwear and signposting that new shoe purchases should include measuring feet to ensure a good fit is recommended.

From outcome measurement to improving health outcomes after lower limb amputation-A narrative review exploring outcome measurement from a clinical practice perspective.

Outcome measurement is essential to understand the impact of clinical interventions and the performance of services. Despite national and professional body encouragement, and successful examples of system level outcome measurement within some health care settings, many barriers still exist preventing outcome measurement from becoming embedded in clinical practice. This paper presents a narrative review which aims to describe the state of the outcome measurement evidence base in prosthetic rehabilitation, as applied in clinical practice, with a view to identifying areas for future work aimed at making outcome measurement in prosthetic rehabilitation a meaningful reality. A literature search of four databases was undertaken, following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis principals appropriate to narrative reviews, and using the search terms outcome, measur*, tool, scale, instrument, prosthe*, amput* and limb loss. A total of 1116 papers were identified. Following screening 35 papers, focusing on four main themes, were included in the review. Themes were: 1) What outcome domains should be measured? 2) How can these outcome domains be measured? 3) What are the barriers to outcome measurement? and 4) What can be learnt from examples of ROM in prosthetic rehabilitation? Findings suggest that successful outcome measurement is multifaceted. Understanding and embedding value at every step appears to be key to success. Addressing the questions of 'what' outcome domains to measure and 'how' to measure them, may help establish consensus. Routine outcome measurement practice at the clinical level should ensure data collection is valuable to clinical practice, makes use of information technology solutions and has organisational engagement.

Past the tipping point: a qualitative study of the views and experiences of men with haemophilia regarding mobility, balance, and falls.

PURPOSE: The life expectancy of people with haemophilia is increasing due to improved medical care. This improvement is accompanied by the co-morbidities of ageing, which include musculoskeletal degeneration and the associated effect on proprioception and balance. This study aims to explore the views and everyday experiences of those living with haemophilia regarding this. MATERIALS AND METHODS: Nine people with moderate or severe haemophilia aged 43-58 years participated in semi-structured interviews and thematic analysis was used to examine the data. RESULTS: Participants described pain and reduced movement in joints as a result of repeated bleeds, which caused problems with mobility and balance. Constant vigilance of their surroundings together with the potential consequences of bleeds caused continual worry. Participants were resourceful in their strategies to cope with the effects of haemophilia, to reduce pain and to minimise the risk of falling. However, participants felt stigmatised because of their condition. CONCLUSION: People with haemophilia have difficulties with their mobility and balance that can increase their risk of falling. Healthcare professionals need to understand and address the physical and psycho-social factors that contribute to the risk of falls. A multi-disciplinary approach to devise effective strategies to counteract and monitor the risk of falls would be useful.Implications for RehabilitationHealthcare professionals should identify movements that are fearful and work on ways to increase confidence and ability to perform these.Healthcare professionals need to identify the recovery strategies used to maintain balance and build these movements into home exercise programmes.Effective pain reduction strategies, both pharmacological and non-pharmacological, need to be investigated and optimised.Footwear choice has implications for both pain reduction and balance and should be discussed in routine reviews.Optimising vision would maximise visual input to aid balance.

Co-creation and User Perspectives for Upper Limb Prosthetics.

People who either use an upper limb prosthesis and/or have used services provided by a prosthetic rehabilitation centre, experience limitations of currently available prosthetic devices. Collaboration between academia and a broad range of stakeholders, can lead to the development of solutions that address peoples' needs. By doing so, the rate of prosthetic device abandonment can decrease. Co-creation is an approach that can enable collaboration of this nature to occur throughout the research process. We present findings of a co-creation project that gained user perspectives from a user survey, and a subsequent workshop involving: people who use an upper limb prosthesis and/or have experienced care services (users), academics, industry experts, charity executives, and clinicians. The survey invited users to prioritise six themes, which academia, clinicians, and industry should focus on over the next decade. The prioritisation of the themes concluded in the following order, with the first as the most important: function, psychology, aesthetics, clinical service, collaboration, and media. Within five multi-stakeholder groups, the workshop participants discussed challenges and collaborative opportunities for each theme. Workshop groups prioritised the themes based on their discussions, to highlight opportunities for further development. Two groups chose function, one group chose clinical service, one group chose collaboration, and another group chose media. The identified opportunities are presented within the context of the prioritised themes, including the importance of transparent information flow between all stakeholders; user involvement throughout research studies; and routes to informing healthcare policy through collaboration. As the field of upper limb prosthetics moves toward in-home research, we present co-creation as an approach that can facilitate user involvement throughout the duration of such studies.

The trouble with footwear following stroke: a qualitative study of the views and experience of people with stroke.

Purpose: Foot problems and suboptimal footwear are risk factors for falls among the elderly. Footwear choice may, therefore, be important for people with balance impairment following stroke, but little is known about their experience. This study explored foot problems experienced following stroke, factors influencing footwear choices and views of footwear in use.Methods: Semi-structured interviews with 15 people with stroke, purposively sampled from respondents to a screening survey.Results: Participants typically experienced impaired mobility with balance problems and felt at risk of falling. Stroke related foot problems, including altered sensation, edema, and foot drop, predominantly on the stroke affected side, influenced footwear priorities. Footwear choices prioritized comfort, security, and convenience, sometimes in tension with concern about appearance. Challenges included choosing appropriate indoor footwear and finding shoes to accommodate their orthoses and edema. Participants highlighted perceived lack of footwear advice from health care professionals and variable experience of shoe shopping.Conclusions: Foot problems, as well as gait and balance impairment, have implications for footwear priorities following stroke, but people felt unsupported in making healthy footwear choices. Health care professionals could be trained to routinely deliver footwear assessment and advice and facilitate referrals to podiatrist, when appropriate.Implications for rehabilitationFoot problems, as well as gait and balance impairment, have implications for footwear priorities following stroke.People with stroke perceive a lack of professional advice about footwear and feel unsupported making healthy footwear choices.Health care professionals could be trained to routinely deliver an initial footwear assessment and advice as part of stroke rehabilitation.A greater transparency and knowledge of referral pathways into podiatry services for Health care professionals and patients would give access to specialist advice where appropriate.

Experiences of mobility for people living with rheumatoid arthritis who are receiving biologic drug therapy: implications for podiatry services.

BACKGROUND: Despite significant advancements in new treatment modalities for rheumatoid arthritis with biological therapies, foot complications remain a disabling and common feature of the disease. In this study the aim was to explore and describe the personal experiences of people with rheumatoid arthritis in receipt of biologic treatments in a bid to understand the impact of this form of medication on their mobility. METHODS: An interpretative phenomenological analysis (IPA) was undertaken to explore in depth the individual experience of rheumatoid disease through personal accounts of the patient journey spanning both 'before' and 'after' the instigation of biologic therapy. A purposive sampling strategy was adopted and in-depth semi structured interviews used to facilitate rich, detailed interview data exploring the lived experiences of individuals undertaking biological therapy and the changes to mobility experienced as a result. Thematic analysis was employed with an IPA framework to identify key meanings, and report patterns within the data. RESULTS: Five people with rheumatoid arthritis participated in the study. The mean disease duration was 20.2 years (range: 6 -32) and all were being treated with biologic therapies. Four key themes emerged from the data: 1) Life before biologic treatment, depicted in accounts as a negative experience characterised by painful and disabling symptoms and feelings of hopelessness. 2) Life with biologic treatment, often experienced as a life changing transition, restoring function and mobility and offering renewed hope. 3) Sense of self, in which the impact of rheumatoid disease and the subsequent changes arising from biologic therapy reveal a profound impact on feelings of personal identity both pre and post biologic therapy; an effect of footwear on self-image emerges as a dominant sub theme; 4) Unmet footcare needs were evident in the patient narrative, where the unrelenting if diminished impact of foot pain on mobility was viewed in the context of problematic access to foot health services. CONCLUSION: Whilst the findings from this study mirror those within the existing literature, which report improvements in physical function related to biological therapy, foot problems clearly remained an unremitting feature of life for patients with rheumatoid disease, even when in receipt of biologics.

A survey exploring self-reported indoor and outdoor footwear habits, foot problems and fall status in people with stroke and Parkinson's.

BACKGROUND: Ill-fitting shoes have been implicated as a risk factor for falls but research to date has focused on people with arthritis, diabetes and the general older population; little is known about people with neurological conditions. This survey for people with stroke and Parkinson's explored people's choice of indoor and outdoor footwear, foot problems and fall history. METHODS: Following ethical approval, 1000 anonymous postal questionnaires were distributed to health professionals, leads of Parkinson's UK groups and stroke clubs in the wider Southampton area, UK. These collaborators handed out survey packs to people with a confirmed diagnosis of stroke or Parkinson's. RESULTS: Three hundred and sixty three completed surveys were returned (218 from people with Parkinson's and 145 from people with stroke). Most respondents wore slippers indoors and walking shoes outdoors and considered comfort and fit the most important factors when buying footwear. Foot problems were reported by 43 % (95 % confidence intervals 36 to 52 %; stroke) and 53 % (95 % confidence interval 46 to 59 %; Parkinson's) of respondents; over 50 % had never accessed foot care support. Fifty percent of all respondents reported falls. In comparison to non-fallers, a greater proportion of fallers reported foot problems (57 %), with greater proportions reporting problems impacting on balance and influencing choice of footwear (p < 0.01) in comparison to non-fallers in each case. Forty-seven percent of fallers with foot problems had not accessed foot care support. CONCLUSIONS: Many people with stroke and Parkinson's wear slippers indoors. A high percentage of these individuals reported both foot problems and falls impacting on footwear habits and choice of footwear; however many did not receive foot care support. These findings highlight that further exploration of footwear and foot problems in these populations is warranted to provide evidence based advice on safe and appropriate footwear to support rehabilitation and fall prevention.

Exploring positive adjustment in people with spinal cord injury.

This study explored adjustment in people with spinal cord injury; data from four focus groups are presented. Thematic analysis revealed four themes, managing goals and expectations, comparison with others, feeling useful and acceptance, showing participants positively engaged in life, positively interpreted social comparison information and set realistic goals and expectations. These positive strategies show support for adjustment theories, such as the Cognitive Adaptation Theory, the Control Process Theory and Response Shift Theory. These results also provide insight into the adjustment process of a person with spinal cord injury and may be useful in tailoring support during rehabilitation.

Attitudes and beliefs that predict older people's intention to undertake strength and balance training.

Many older people refuse to participate in programs of strength and balance training (SBT), limiting their effectiveness for falls prevention. To persuade older people to take up SBT, we need to know whether their intention to undertake SBT is motivated by the perceived threat of falling or the perceived suitability and benefits of SBT. A survey of 558 people aged 60 to 95 years assessed intention to undertake SBT, as well as measures of threat appraisal (concern about falling, perceived risk, and consequences of falling) and coping appraisal (perceived benefits and appropriateness for them of undertaking SBT). Intention to undertake SBT was much more closely related to all elements of coping appraisal than to threat appraisal. The elements of coping appraisal included the belief that it has multiple benefits and is associated with a positive social identity, and the feeling that family, friends, and doctors would approve of taking part.

Effectiveness of primary care-based vestibular rehabilitation for chronic dizziness.

BACKGROUND: Dizziness is a very common symptom and is usually managed in primary care. Vestibular rehabilitation for dizziness is a simple treatment that may be suitable for primary care delivery, but its effectiveness has not yet been determined. OBJECTIVE: To evaluate the effectiveness of nurse-delivered vestibular rehabilitation in primary care for patients with chronic dizziness. DESIGN: Single-blind randomized, controlled trial. SETTING: 20 general practices in southern England. PATIENTS: 170 adult patients with chronic dizziness who were randomly assigned to vestibular rehabilitation (n = 83) or usual medical care (n = 87). INTERVENTION: Each patient received one 30- to 40-minute appointment with a primary care nurse. The nurse taught the patient exercises to be carried out daily at home, with the support of a treatment booklet. MEASUREMENTS: Primary outcome measures were baseline, 3-month, and 6-month assessment of self-reported spontaneous and provoked symptoms of dizziness, dizziness-related quality of life, and objective measurement of postural stability with eyes open and eyes closed. RESULTS: At 3 months, improvement on all primary outcome measures in the vestibular rehabilitation group was significantly greater than in the usual medical care group; this improvement was maintained at 6 months. Of 83 treated patients, 56 (67%) reported clinically significant improvement compared with 33 of 87 (38%) usual care patients (relative risk, 1.78 [95% CI, 1.31 to 2.42]). LIMITATIONS: Psychological elements of the therapy may have contributed to outcomes, and the treatment may be effective only for well-motivated patients. CONCLUSIONS: Vestibular rehabilitation delivered by nurses in general practice improves symptoms, postural stability, and dizziness-related handicap in patients with chronic dizziness.
