Mobility in persons with lower extremity amputations and influencing factors: Using the International Classification of Functioning, Disability and Health to quantify expert views

Development of a Core Outcome Set for users and funders of lower-limb prosthetic interventions (PI-COS): a step to inform the benefits measured in prosthetic health economic evaluations

PURPOSE

Little is known about the outcomes that are most important to prosthesis users and funders. A Prosthetic Interventions Core Outcome Set (PI-COS) will help researchers and practitioners measure outcomes that are the most important to prosthesis users and funders.

MATERIALS AND METHODS

Prosthesis users and funders rated the importance of 121 International Classification of Functioning, Disability, and Health (ICF) second-level categories using a two-round Delphi survey. A Consensus Meeting using the nominal group technique resolved rating differences between groups. The ICF second-level categories were ranked according to importance and a K-Means Cluster Analysis helped establish the PI-COS.

RESULTS

65 users and 8 funders completed the Delphi surveys, followed by a Consensus Meeting. 26 ICF second-level categories were considered important to prosthesis users and funders and a PI-COS of 14 ICF second-level categories drawn predominantly from five ICF chapters was established: Sensory Functions and Pain (b2), Neuromusculoskeletal and Movement-related Functions (b7), General Tasks and Demands (d2), Mobility (d4), and Products and Technology (e1).

CONCLUSIONS

The PI-COS describes the outcomes that are most important to prosthesis users and funders. The PI-COS can help focus on the most important outcome measures in clinical practice and research, including future prosthetic health economic evaluations.

Development of the ECLIPSE model of meaningful outcome domains following lower limb amputation and prosthetic rehabilitation, through systematic review and best fit framework synthesis

BACKGROUND

Little is known about which outcome domains characterise meaningful recovery following prosthetic rehabilitation and should be measured. Our previous qualitative work developed a conceptual model of outcome domains which are meaningful to patients. This qualitative synthesis aims to develop that model by exploring views and experiences of recovery captured in the limb loss literature, and use these to produce a second iteration of the model describing outcome domains of importance following prosthetic rehabilitation from the patient's perspective.

METHODS

Systematic searches were conducted using CINAHL, Psychinfo and Web of Science from 2011 to early 2023. Studies with a qualitative design focusing on views and experiences of lower limb prosthetic users were eligible for inclusion. Quality was assessed using the CASP tool. 'Best Fit' framework synthesis was used to synthesise the evidence and develop the conceptual model.

RESULTS

40 studies were included, describing the experiences of 539 participants. Data supported the pre-existing conceptual model and led to development of four of the five domains. The newly named ECLIPSE model describes meaningful outcome domains as 1) Being able to participate in important activities and roles, 2) Participating in the way I want to, 3) My prosthesis works for me, 4) If I am in pain, I can manage it, and 5) I am able to accept my new normal. Studies came from 15 countries showing good coverage of high-income settings. Few participants from low-and-middle-income countries were included, it is unclear if the ECLIPSE model describes outcome domains of importance in these settings.

CONCLUSIONS

This synthesis provides a rigorous foundation for understanding outcome domains of importance following lower limb prosthetic rehabilitation from the patient's perspective. The ECLIPSE model is an accessible representation of recovery which could direct rehabilitation programmes, as well as inform the evaluation of prosthetic care through the selection of outcome measures.

Leveraging Digital Workflows to Transition the Orthotics and Prosthetics Profession Toward a Client-Centric and Values-Based Care Model

The orthotics and prosthetics (O&P) profession has a history of responding to market demands in a reactive rather than proactive manner. This has created significant impacts including shrinkage in scope of practice and constraint in remuneration for professional services due to a fee-for-device third party payer system. Rapid changes in technology and healthcare combined with an outdated device-centric reimbursement system are creating unprecedented challenges that threaten sustainability of the O&P profession. Hence, a reassessment of the value of O&P care, and the O&P workflow process is necessary to inform an update to the value proposition and practice model for sustainability. This article reviews key factors contributing to the current state of O&P, and potential solutions involving an update in practitioner competencies, and the care delivery model (from device-centric to client-centric and values-based). Updates could be achieved by leveraging the use of digital workflows that increase efficiencies and enhance the value of clinical outcomes. Eventually, these updates could enable the O&P profession to elevate the value proposition that aligns with its most important stakeholders: client-patients and third-party reimbursement agencies in a rapidly changing technology and healthcare landscape.

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.

Identifying and linking prosthetic outcomes to the ICF framework: a step to inform the benefits measured in prosthetic health economic evaluations

PURPOSE

Prosthetic research seems focused on measuring gait-related outcomes that may not adequately measure real-world benefits of prosthetic interventions. Systematically cataloguing a comprehensive range of outcomes is an important steppingstone towards developing a holistic way to measure the benefits of prosthetic interventions for future health economic evaluations. The purpose of this research was to identify and catalogue the outcomes measured in lower-limb prosthetic research using the International Classification of Functioning, Disability, and Health (ICF) framework and a custom clinical framework, and thereby describe the existing research focus and identify evidence gaps.

MATERIALS AND METHODS

A structured literature search identified systematic reviews of lower-limb prosthetic interventions. Reported outcomes were extracted from included studies and linked to the ICF- and clinical-frameworks.

RESULTS

Of the 1297 extracted outcomes, 1060 were linked to the ICF framework. Most outcomes linked to second- (63.8%) or third-level categories (33.4%), such as Gait Pattern Functions (b770, 49.8%). Most of these outcomes (31.2%) describe temporospatial, kinematic or kinetic gait measures as categorised by the clinical framework.

CONCLUSIONS

Lower-limb prosthetic research is focused on laboratory-based measures of gait. There are evidence gaps describing participation in real-world activities - important outcomes to inform policy and investment decisions that determine the prosthetic interventions available for people with limb-loss.Implications for rehabilitationCataloguing the outcomes used in prosthetic research to the International Classification of Functioning, Disability, and Health (ICF) allows important evidence gaps to be illuminated given the holistic description of function and disability.Establishing a comprehensive list of prosthetic outcomes, described using an internationally recognised framework with unified and consistent language, is an important steppingstone towards developing a core outcome set (COS) for prosthetic interventions and informing the benefits measured in future prosthetic health economic evaluations (HEEs).Being able to measure the benefits of a prosthesis that are most important to prosthesis users and funders has potential to fundamentally change future HEEs that influence funding policies, and ultimately the prostheses made available to people living with limb-loss.

Factors influencing the self-perceived mobility of active unilateral lower limb amputees assessed with the Prosthetic Mobility Questionnaire: a brief report

The Prosthetic Mobility Questionnaire (PMQ 2.0) represents a reliable solution for evaluating amputees' self-perceived mobility. The study aimed to evaluate the perceived mobility of middle-aged users with a traumatic amputation using the PMQ 2.0 and to assess the influence of age, stump and phantom limb pain, amputation level, time since amputation, and prosthesis use on it. Fifty subjects were recruited. The median value of the score was higher than previously published reference values, reflecting the 'active' mobility status of the sample. The hours of prosthesis use per day explained about 21% of the variance of the questionnaire score and was a significant predictor of perceived mobility. Reference values for the recently developed PMQ 2.0 survey and relative to active, traumatic amputees were reported. As prosthesis use was a significant predictor of the amputees' perceived mobility, prolonged use of the artificial limb should be always encouraged in clinical practice.

Electroencephalogram-based neurofeedback training in persons with stroke: A scoping review in occupational therapy

BACKGROUND

Neurofeedback training targets the relevant brain response under minimal stress. It could be a promising approach for the treatment of patients with brain injury.

OBJECTIVE

This review aimed to examine the existing literature to confirm the effectiveness of applied electroencephalogram (EEG)-based neurofeedback training in the area of occupational therapy for upper limb stroke rehabilitation.

METHOD

All relevant literature published until July 1, 2020 in five prominent databases (PubMed, CINAHL, PsycINFO, MEDLINE Complete, and Web of Science) was reviewed, based on the five-step review framework proposed by Arksey and O'Malley.

RESULTS

After a thorough review, a total of 14 studies were included in this review. Almost studies reported significant improvements as a result of EEG-based neurofeedback training, but this had not always account for the differences in effectiveness between groups. However, the results of these studies suggested that neurofeedback training was effective as compared to the traditional treatment and more effective in combination with EEG than that with simple equipment application.

CONCLUSION

This review demonstrated the effectiveness of the combination of occupational therapy and EEG-based neurofeedback training. Most of these treatments are intended for inpatients, but they may be more effective for outpatients, especially if customized to their requirements. Also, such explorations to assess the suitability of the treatment for patient rehabilitation will help reduce barriers to effective interventions. An analysis of the opinions of participants and experts through satisfaction surveys will be helpful.

The most important activities of daily functioning: the opinion of persons with lower limb amputation and healthcare professionals differ considerably

The aim of this study is to determine the 15 most important daily activities according to persons with lower limb amputation (LLA) and healthcare professionals. Persons with LLA (n = 125) and healthcare professionals (n = 44) filled in a questionnaire. Participants had to select 10 items out of a list of 40 items on the domains activity and/or participation. Selection criterion was what they considered to be most important to perform independently and order the selected 10 items from most to least important. Mean rank scores of the 15 highest scored items according to participants with LLA were compared with the mean rank scores given by professionals, using the Mann-Whitney U test with a Hochberg adjustment for multiple testing. Participants with LLA rated five activities as significantly more important compared to professionals: 'driving a car', 'bicycling', 'ascending/descending stairs', 'heavy exercise', and 'preparing meals'. Healthcare professionals rated four activities as significantly more important compared to persons with LLA: 'going to the toilet', 'getting in and out bed', 'walking around outdoors', and 'walking around indoors'. A significant difference in rating importance was present in 9 out of 15 activities between persons with LLA and healthcare professionals. This result makes it all the more clear how complex shared decision making can be and how important it is for healthcare professionals to communicate with the person with LLA.
