Living with limb loss: everyday experiences of “good” and “bad” days in people with lower limb amputation

The impact of a customized aesthetic prosthetic leg cover on social interaction cues and attitudes in the general UK population: Two experimental studies

OBJECTIVES

To explore the impact of an aesthetic prosthetic leg cover on attitudes toward individuals with lower-limb amputation and associated social interaction cues among the general UK population.

STUDY DESIGN

Two novel experimental methodologies.

METHODS

In study 1, participants (n = 188) viewed 1 of 3 images of an individual: (1) wearing a traditional stem prosthetic, (2) wearing an aesthetic leg cover, or (3) as a nonamputee. They then completed an attitude scale and rated the personality of the individual using the 10-item Big Five Inventory. Study 2 (n = 31) used eye tracking and facial expression software to explore gaze and facial arousal when viewing 1 of 9 manipulated videos of the same individual talking about 3 different scenarios.

RESULTS

In study 1, the aesthetic leg cover led to significantly higher ratings of agreeableness than stem and nonamputee images and significantly higher ratings of extraversion than the nonamputee image. Attitudes toward an individual with a prosthesis did not significantly differ depending on which image they viewed and were generally positive. In study 2, all participants focused mainly on the individual's face regardless of scenario topic or leg condition, although participants focused more around the leg cover in more active contexts.

CONCLUSIONS

Customized aesthetic leg covers may help individuals living with amputation to be perceived more positively in social situations. These experimental methodologies could be extended to explore the differential impact of context, functionality, and activity of specific types of customized aesthetic prosthetics and could help inform shared decision-making processes in clinical settings.

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.

Resources, relationships, and resilience: The psychosocial experiences of women with lower limb absence during pregnancy and postpartum

BACKGROUND

There is limited research on the unique needs of women with lower limb absence (LLA) during pregnancy and postpartum. The lack of information can negatively impact women's physical and emotional experiences.

OBJECTIVE

The purpose of this study is to explore the psychosocial experiences of individuals with LLA through the pregnancy and postpartum periods, and to provide information to women and health care providers (HCPs) on what they can expect.

METHODS

Semi-structured interviews were conducted with 19 women with LLA who had been pregnant in the previous 10 years. Interviews were analyzed using thematic analysis.

RESULTS

Participants experienced uncertainty due to a lack of information and limited resources related to pregnancy and LLA. While most women had strong support networks including family, other mothers with LLA and HCPs, some women faced stigma or judgement from HCPs and people in their social networks. Some women had periods where they struggled mentally due to a temporary loss of independence. Despite these challenges, they demonstrated tremendous resilience and noted that their ability to adapt helped them to navigate the difficulties they experienced in the perinatal period (PNP).

CONCLUSION

There is an immediate need to fill the 'information gap' about pregnancy and LLA. We recommend the development of support networks, informational guidelines, and further education for HCPs to better support women with LLA through the PNP. Further research is warranted to gain a better understanding of the mental health experiences of women with LLA in the PNP.

Experiences of persons with lower limb amputation after prosthetic rehabilitation in Ghana: A qualitative inquiry

BACKGROUND

Lower limb amputations (LLAs) have long been associated with physical, social, and psychological consequences. Individuals with LLAs have challenges with mobility and often become isolated from their social networks. Disability rehabilitation technologies such as prosthetic devices are used to improve the mobility capabilities of lower limb amputees. To improve clinical outcomes, feedback from the prosthetic users is a key element to consider.

OBJECTIVES

The study sort to explore the experiences of lower-limb prosthetic users after prosthetic rehabilitation in a prosthetic and orthotic rehabilitation center in the Eastern Region of Ghana.

STUDY DESIGN

This study adopted an exploratory descriptive qualitative study design.

METHODS

A purposive sampling technique and semistructured interview guide was used to interview 17 participants by the first author. The social model of disability underpinned the study. Lower-limb prosthetic users (≥18 years) with unilateral LLA attending outpatient follow-up at a prosthetic and orthotic rehabilitation center were recruited. The interviews were audio recoded, transcribed verbatim, and analyzed using the procedure for thematic content analysis by Braun and Clarke (2013).

RESULTS

Participants reported injuries and tingling in their residual limb. Internal stigma resulting from negative comments and labeling from the public were reported. Prosthetic users experienced empathy and being treated as weaklings by their family/peers. Participants avoided relationships because of recurrent rejection, embarrassment, fear of sexual abuse, and exploitation. As a coping method, some participants chose to isolate themselves to avoid humiliation and public disgrace. Other coping mechanisms included watching television, listening to music, conversing with others, ignoring criticism, and having faith in God.

CONCLUSION

Participants' narrative in this study gave insight into the varied lived experiences on the individual level, family/peer level, and the coping mechanisms used. Challenges relating to discomfort from the prosthesis, internal stigma, relationship avoidance, and altered sexual life should be given much attention and used in implementing initiatives to improve clinical outcomes.

Lower limb prosthesis users' perceptions of everyday life-A phenomenographic study

INTRODUCTION

A lack of understanding of personal experiences related to limb amputation and prosthetic use limits the extent to which clinicians involved in rehabilitation can support and advise their clients in a person-centered consultation. The objective of this qualitative study was to explore the personal experience of daily life as a lower limb prosthesis user.

METHODS

Fifteen lower limb prosthesis users participated in individual semistructured interviews. Transcripts were analyzed using a phenomenographic approach.

RESULTS

The extent to which prosthesis users were able to adjust to their impairment and move on with their life was influenced by social interactions with other prosthesis users, access to relevant information about prosthetic solutions that may benefit them, and finding a balance between desired activities and their physical and/or cognitive capacity.

CONCLUSIONS

After a period of existential adjustment, prosthesis users described themselves as living active, fulfilling lives. This was facilitated to a large extent by social interactions with other prosthesis users and access to information they perceived as relevant. Social media plays a particularly important role in establishing connections with other prosthesis users and is perceived as a useful source of information.

Narrative Experiences of Individuals with Lower Limb Amputation: A Qualitative Study

Aim: The present study aimed to determine the narrative experiences of individuals undergoing lower limb amputation. Method: This study was a qualitative study conducted using the phenomenological pattern. Using purposive sampling, 13 individuals with lower limb amputation were selected and interviewed. Data were collected using semi-structured interviews and analyzed using the content analysis method. Results: The mean age of the 13 individuals was 51.17 ± 8.7 years. Five of the individuals were female and eight of them were male. A main theme and four sub-themes were identified. This main theme together with sub-themes were Dead End (Process of Loss, Negative Feelings, Change, Adapting to New Life). The individuals expressed mostly negative feelings and thoughts while also emphasizing the rehabilitation process (positive sides). Conclusions: Individuals with lower limb amputations stated there were positive factors affecting the rehabilitation process while emphasizing negative thoughts and feelings during the amputation process. These results can be used in planning for training, counseling and therapeutic interviews to protect the psychosocial health of individuals with lower limb amputation.

Veteran Perspectives on Phantom Limb Pain and Non-Drug Interventions

Background

Phantom limb pain (PLP) commonly occurs post-amputation and can negatively affect the daily functioning of persons with amputation. Best practices for medication and non-drug management remain unclear.

Objective

To better understand the PLP experience and patients' familiarity with treatments, phone interviews were conducted at the Minneapolis Veterans Affairs Regional Amputation Center in Veterans with amputations.

Methods

Fifty Veteran participants (average age 66, 96% male) with lower limb amputation were recruited for phone-based data collection of patient-reported outcomes (ie, demographics using the Trinity Amputation and Prosthesis Experience Scales-Revised (TAPES-R) and pain experience using the Phantom Phenomena Questionnaire) to characterize the population and a semi-structured interview. Notes taken during interviews were analyzed using the Krueger and Casey constant comparison analysis method.

Results

Participants had an average of 15 years since amputation, and 80% reported PLP as identified with the Phantom Phenomena Questionnaire. Investigators identified several core themes from the qualitative interviews including 1) high variability in the experience of PLP, 2) acceptance and resilience, and 3) PLP treatment perceptions. The majority of participants reported trying common non-drug treatments with none endorsed consistently as highly effective.

Conclusion

More research is needed to inform identification and implementation of clinical best practices for non-drug interventions for PLP and understand the factors that influence engagement in non-drug interventions. The participants in this study were largely male, so these results may not be generalizable to females.

The Development and Pilot Study of a Multiple Criteria Decision Analysis (MCDA) to Compare Patient and Provider Priorities around Amputation-Level Outcomes

Background. Patients with chronic limb-threatening ischemia who are facing a lower-limb amputation often require a transmetatarsal amputation (TMA) or a transtibial amputation (TTA). A TMA preserves more of the patient's limb and may provide better mobility but has a lower probability of primary wound healing relative to a TTA and may result in additional amputation surgeries. Understanding the differences in how patients and providers prioritize key outcomes may enhance the amputation decisional process. Purpose. To develop and pilot test a multiple criteria decision analysis (MCDA) tool to elicit patient values around amputation-level selection and compare those with provider perceptions of patient values. Methods. We conducted literature reviews to identify and measure the performance of criteria important to patients. Because the quantitative literature was sparse, we developed a Sheffield elicitation framework exercise to elicit criteria performance from subject matter experts. We piloted our MCDA among patients and providers to understand tool acceptability and preliminarily assess differences in patient and provider priorities. Results. Five criteria of importance were identified: ability to walk, healing after amputation surgery, rehabilitation intensity, limb length, and prosthetic/orthotic device ease. Patients and providers successfully completed the MCDA and identified challenges in doing so. We propose potential solutions to these challenges. The results of the pilot test suggest differences in patient and provider outcome priorities. Limitations. The pilot test study enrolled a small sample of providers and patients. Conclusions. We successfully implemented the pilot study to patients and providers, received helpful feedback, and identified solutions to improve the tool. Implications. Once modified, our MCDA tool will be suitable for wider rollout.

Highlights

Patients and providers have successfully completed our MCDA, and patients feel the MCDA may be useful in clinical practice.We encountered several methodologic challenges and identified approaches to ease participant burden.When data are sparse, using the Sheffield elicitation framework is helpful in creating a performance matrix, although patients relied largely on their amputation experiences to complete the exercise. Blinding the alternatives may help patients better understand the process.

A review of user needs to drive the development of lower limb prostheses

Background

The development of bionic legs has seen substantial improvements in the past years but people with lower-limb amputation still suffer from impairments in mobility (e.g., altered balance and gait control) due to significant limitations of the contemporary prostheses. Approaching the problem from a human-centered perspective by focusing on user-specific needs can allow identifying critical improvements that can increase the quality of life. While there are several reviews of user needs regarding upper limb prostheses, a comprehensive summary of such needs for those affected by lower limb loss does not exist.

Methods

We have conducted a systematic review of the literature to extract important needs of the users of lower-limb prostheses. The review included 56 articles in which a need (desire, wish) was reported explicitly by the recruited people with lower limb amputation (N = 8149).

Results

An exhaustive list of user needs was collected and subdivided into functional, psychological, cognitive, ergonomics, and other domain. Where appropriate, we have also briefly discussed the developments in prosthetic devices that are related to or could have an impact on those needs. In summary, the users would like to lead an independent life and reintegrate into society by coming back to work and participating in social and leisure activities. Efficient, versatile, and stable gait, but also support to other activities (e.g., sit to stand), contribute to safety and confidence, while appearance and comfort are important for the body image. However, the relation between specific needs, objective measures of performance, and overall satisfaction and quality of life is still an open question.

Conclusions

Identifying user needs is a critical step for the development of new generation lower limb prostheses that aim to improve the quality of life of their users. However, this is not a simple task, as the needs interact with each other and depend on multiple factors (e.g., mobility level, age, gender), while evolving in time with the use of the device. Hence, novel assessment methods are required that can evaluate the impact of the system from a holistic perspective, capturing objective outcomes but also overall user experience and satisfaction in the relevant environment (daily life).

Sex and gender differences in quality of life and related domains for individuals with adult acquired lower-limb amputation: a scoping review

PURPOSE

To understand what is known about sex and gender differences in quality of life (QoL) and related domains for individuals with an adult acquired lower limb amputation (LLA).

METHODS

A computer-assisted literature search of four online databases was completed. Articles were included if they incorporated sex or gender as part of their data analysis with a focus on QoL-related domains. Data were analyzed using descriptive numerical analysis and thematic analysis.

RESULTS

One hundred and eleven articles were included in this review. Women were under-represented across studies, with most of the participants being men. No articles described the inclusion of trans or non-binary persons. Differences by sex or gender were reported by 66 articles. Articles reporting on gender seldom provided descriptions of how gender was defined. Overall, women/females seemed to have worse outcomes in terms of prosthesis-related outcomes, mental health, and return to occupations.

CONCLUSION

Articles included in this review were not clear with how gender was defined. In order for more targeted interventions that account for sex and gender differences, studies need to be more forthcoming about how they use and define gender. Future research should seek to include gender non-conforming participants to identify additional needs.Implications for rehabilitationSex and gender are important constructs that influence outcomes following lower limb amputation.Rehabilitation professionals should consider sex and gender-specific outcomes when tailoring programs to ensure ethical clinical care.

Amputation-specific and generic correlates of participation among Veterans with lower limb amputation

Participation in valued interpersonal and community activities is a key component of rehabilitation for Veterans with amputation. The purpose of this study was to identify specific factors that promote or inhibit participation to inform development of interventions that may facilitate participation in desired life activities. A convenience sample of 408 Veterans with at least one lower limb amputation and who had received outpatient care from the Regional Amputation Center (RAC) completed a mailed survey. Participation was measured using the Community Participation Indicators (CPI) Importance, Control, and Frequency scales and the Patient Reported Outcome Measurement Information System (PROMIS) Ability to Participate in Social Roles and Satisfaction with Social Participation scales. Multiple imputation procedures were used to address missing data. Correlates of participation were examined through multiple linear regression. A total of 235 participants completed the survey, a response rate of 58%. Levels of participation, measured with the PROMIS instruments, were 43.2 (SD = 8.1) for Ability and 46.4 (SD = 8.6) for Satisfaction. Regression analyses found robust amputation-specific correlates for participation, including body image and balance confidence. Generic (non-amputation specific) correlates for participation included depression and pain interference. Development of treatment approaches and devices that can address body image, balance confidence, pain, and mental health concerns such as depression have the potential to enhance the participation and rehabilitation of Veterans with lower limb amputation.

"I Wish I Could Have My Leg": A Qualitative Study on the Experiences of Individuals With Lower Limb Amputation

Amputation is commonly regarded as a lifesaving procedure. However, the loss of a body part can lead to permanent disability that can impact patients physically, psychologically, and socially. The aim of this study was to describe and understand the perspectives of patients with lower limb amputation (LLA) about their condition. The study uses a descriptive phenomenological design. Data were collected from 12 patients. The researchers conducted interviews using semi-structured questions. MAXQDA was used for qualitative software support in managing the interview data. Data were transcribed. The participants were aged 61.3 ± 10.8 years. Three themes emerged from the qualitative data: (i) losing control over one's own life, (ii) dreams versus the realities of life, and (iii) future perceptions. Most of the participants emphasized that they face undesirable experiences in their post-amputation lives. The findings of the present study provide novel insight into how individuals subjectively experience life after LLA.

A qualitative study examining prosthesis use in everyday life in individuals with lower limb amputations

BACKGROUND

Lower limb amputation (LLA) is a life-changing event that affects functional mobility and participation in everyday life. Prostheses provide individuals with LLA the opportunity to improve mobility and quality of life; however, existing literature suggests that there is underuse of prostheses.

OBJECTIVES

The purpose of this study is to describe how individuals with major LLA use their prosthesis in everyday life and describe barriers and facilitators that influence prosthesis use.

STUDY DESIGN

A qualitative descriptive methodology was used.

METHODS

Ten community dwelling adults (>18 years) with unilateral major LLAs (transtibial, transfemoral, and knee disarticulation) attending outpatient follow-up at a specialized rehabilitation center were recruited. Participants were purposively sampled for variation in prosthesis use and level of amputation. One-on-one semistructured in-depth interviews were conducted in person or by telephone. The interviews were audio recorded, transcribed verbatim, and analyzed inductively using thematic analysis.

RESULTS

The experiences of individuals with major LLA were organized into three overarching themes: everyday experiences using a prosthesis, extrinsic factors influencing prosthesis use, and intrinsic factors influencing prosthesis use. These themes, and their associated subthemes, highlight how individuals use their prosthesis and the various factors perceived to act as barriers and facilitators to prosthesis use in everyday life.

CONCLUSIONS

These findings provide valuable insight into the everyday experiences of individuals with LLA and can be used to implement strategies to optimize prosthesis use.

AAAPT Diagnostic Criteria for Acute Neuropathic Pain

OBJECTIVE

Acute neuropathic pain is a significant diagnostic challenge, and it is closely related to our understanding of both acute pain and neuropathic pain. Diagnostic criteria for acute neuropathic pain should reflect our mechanistic understanding and provide a framework for research on and treatment of these complex pain conditions.

METHODS

The Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) public-private partnership with the U.S. Food and Drug Administration (FDA), the American Pain Society (APS), and the American Academy of Pain Medicine (AAPM) collaborated to develop the ACTTION-APS-AAPM Pain Taxonomy (AAAPT) for acute pain. A working group of experts in research and clinical management of neuropathic pain was convened. Group members used literature review and expert opinion to develop diagnostic criteria for acute neuropathic pain, as well as three specific examples of acute neuropathic pain conditions, using the five dimensions of the AAAPT classification of acute pain.

RESULTS

AAAPT diagnostic criteria for acute neuropathic pain are presented. Application of these criteria to three specific conditions (pain related to herpes zoster, chemotherapy, and limb amputation) illustrates the spectrum of acute neuropathic pain and highlights unique features of each condition.

CONCLUSIONS

The proposed AAAPT diagnostic criteria for acute neuropathic pain can be applied to various acute neuropathic pain conditions. Both the general and condition-specific criteria may guide future research, assessment, and management of acute neuropathic pain.

Investigation of Orthopedic Prosthesis Socket Management after Transfemoral Amputation by Expert Survey

Prosthesis treatment requires the close interaction of different actors. In fitting prostheses to patients, special attention is given to the manufacturing of the socket. The continuous development of the technologies involved in the fitting and optimization of prostheses is shown in the literature. The assessment of orthopedic technicians and their influence in the process is thus far largely unexplored. Ten orthopedic technicians were interviewed about the socket fitting process after transfemoral amputation. The research goal was to clarify the socket treatment process with regards to the German context. The results showed that the orthopedic technicians focussing on the patient during the fitting process. This study underlines the importance of interaction and empathy. Volume fluctuations are decisive within the treatment process and are interactively influenced by various factors. Furthermore, the research emphasizes the need for appropriate assistive technologies and the potential for the further development of existing systems.

The comprehensive lower limb amputee socket survey: Reliability and validity of the persian version

BACKGROUND

The Comprehensive Lower limb Amputee Socket Survey (CLASS) is a self-reported measure developed to assess prosthetic socket fit in individuals with lower limb amputation.

OBJECTIVE

To assess the reliability and validity of the Persian version of the CLASS.

STUDY DESIGN

Cross-sectional and repeated-measures.

METHODS

We evaluated the translation and back translation of the CLASS and made the required changes according to expert committee feedback. Then, we recruited 124 participants with unilateral lower limb amputation (89.5% men). Internal consistency was analyzed with Cronbach's alpha and test-retest reliability using intra-class correlation coefficients. Convergent construct validity was assessed by comparing the CLASS scores with the Persian version of the Trinity Amputation and Prosthesis Experience Scales (TAPES) scores. In addition, known groups construct validity was assessed by comparing CLASS scores between groups with different causes and levels of amputation.

RESULTS

Cronbach's alpha coefficient represented a very good internal consistency for all domains of the Persian CLASS (ranged from 0.86 to 0.92). The intra-class correlation coefficient for test-retest reliability for the Persian CLASS was good to excellent (ranged from 0.73 to 0.97). There was a significant correlation between the subscales of the Persian CLASS and satisfaction subscales of the Persian TAPES (p < 0.001). There was significant difference between comfort subscale of the Persian CLASS scores by level of amputation.

CONCLUSION

The Persian CLASS is a reliable and valid measure for evaluating prosthetic socket fit.

Mobility with a lower limb prosthesis: experiences of users with high levels of functional ability

PURPOSE

The Prosthetic Limb Users Survey of Mobility (PLUS-M) is a self-report item bank designed to measure the abilities with which people with lower limb amputation perform physical activities. Although PLUS-M includes items that span a range of mobility, additional items are needed to accurately measure mobility of highly active prosthesis users, such as athletes and service members with lower limb amputation. The aim of this study was to understand mobility in highly active lower limb prosthesis users to inform the development of new items for the PLUS-M item bank.

METHODS

Focus groups were conducted with active, lower limb prosthesis users from across the USA. In-person and online focus groups were conducted by a trained facilitator using a semi-structured guide. Focus group transcripts were reviewed and coded by two researchers. Thematic analysis was used to identify important experiences across participants.

RESULTS

Twenty-nine participants took part in four focus groups. Three resultant themes were identified: mobility after amputation, mobility characteristics, and healthcare providers and systems.

CONCLUSIONS

Identified themes inform clinician and researcher understanding of mobility in highly active lower limb prosthesis users. The results of this study will be used to inform development of high-activity items for the PLUS-M item bank.Implications for rehabilitationParticipants described engagement in high-level activities as a learning process that included elements such as equipment challenges and modifications, pain and injury, and the need to trust the prosthetic limb.Participants with lower limb amputation who use prostheses identified mobility characteristics, such as postural changes, terrain, and obstacles, that influenced their ability to perform high-level activities.High-level mobility characteristics identified in these focus groups can be integrated into a revised version of the Prosthetic Limb Users Survey of Mobility to assess mobility in active adults and athletes with amputation.Rehabilitation professionals play an important role in facilitating access to specialized prosthetic components and training that can help patients achieve their mobility goals and potential.

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.

Pain issues in the victims with lower-limb amputation: 10 years after the 2008 Sichuan earthquake

PURPOSE

To study the prevalence, intensity, and bothersomeness of amputation-related pain and further to identify the potential risk factors in the victims with lower-limb amputation 10 years after the 2008 Sichuan earthquake.

METHODS

In the cross-sectional study, 66 victims with lower-limb amputation were recruited. The Prostheses Evaluation Questionnaire was used to document the prevalence, intensity, and bothersomeness of amputation-related pain. The bivariate relationships between amputation-related pain and each of demographic characteristics were analyzed.

RESULTS

Majority of the enrolled lower-limb amputees (90.9%) reported to have one or more types of amputation-related pain. The intensity and bothersomeness of amputation-related pain were considered as severe in nearly 40% of these post-earthquake victims. The potential demographic risk factors associated with the prevalence, intensity, and bothersomeness of amputation-related pain were identified, including the age, lower level of education, marital status, employment, and comorbidity.

CONCLUSIONS

The pain coming from phantom limb, residual limb, non-amputated limb, and back was found persistent in the lower-limb amputees 10 years after the 2008 Sichuan earthquake. The findings of this study could provide useful reference for optimization of post-disaster rehabilitation strategies to alleviate chronic pain in the victims following lower-limb amputation.Implications for RehabilitationThe pain coming from phantom limb, residual limb, non-amputated limb, and back was found persistent in the victims with lower-limb amputation 10 years after the 2008 Sichuan earthquake.Continuous post-earthquake assessment and management of amputation-related pain should be taken into consideration for the victims with lower-limb amputation.The comorbidity should be effectively and efficiently controlled for the victims with lower-limb amputation due to its association with the intensity and bothersomeness of amputation-related pain.

Technology for monitoring everyday prosthesis use: a systematic review

BACKGROUND

Understanding how prostheses are used in everyday life is central to the design, provision and evaluation of prosthetic devices and associated services. This paper reviews the scientific literature on methodologies and technologies that have been used to assess the daily use of both upper- and lower-limb prostheses. It discusses the types of studies that have been undertaken, the technologies used to monitor physical activity, the benefits of monitoring daily living and the barriers to long-term monitoring, with particular focus on low-resource settings.

METHODS

A systematic literature search was conducted in PubMed, Web of Science, Scopus, CINAHL and EMBASE of studies that monitored the activity of prosthesis users during daily-living.

RESULTS

Sixty lower-limb studies and 9 upper-limb studies were identified for inclusion in the review. The first studies in the lower-limb field date from the 1990s and the number has increased steadily since the early 2000s. In contrast, the studies in the upper-limb field have only begun to emerge over the past few years. The early lower-limb studies focused on the development or validation of actimeters, algorithms and/or scores for activity classification. However, most of the recent lower-limb studies used activity monitoring to compare prosthetic components. The lower-limb studies mainly used step-counts as their only measure of activity, focusing on the amount of activity, not the type and quality of movements. In comparison, the small number of upper-limb studies were fairly evenly spread between development of algorithms, comparison of everyday activity to clinical scores, and comparison of different prosthesis user populations. Most upper-limb papers reported the degree of symmetry in activity levels between the arm with the prosthesis and the intact arm.

CONCLUSIONS

Activity monitoring technology used in conjunction with clinical scores and user feedback, offers significant insights into how prostheses are used and whether they meet the user's requirements. However, the cost, limited battery-life and lack of availability in many countries mean that using sensors to understand the daily use of prostheses and the types of activity being performed has not yet become a feasible standard clinical practice. This review provides recommendations for the research and clinical communities to advance this area for the benefit of prosthesis users.

Qualitative analysis of resilience characteristics of people with unilateral transtibial amputation

BACKGROUND

Resilience characteristics are a significant factor in the highly variable rehabilitation outcomes for people in middle age or later with transtibial amputation.

OBJECTIVE

The purpose of this study was to describe resilience characteristics meaningful to people with transtibial amputation in middle age or later, who use a prosthesis.

METHODS

Semi-structured interviews were conducted, audio recorded, and transcribed with eighteen participants. Interview transcripts were coded and analyzed using a directed content analysis approach, guided by Charney's theory of resilience and Connor-Davidson Resilience Scale scores.

RESULTS

Five main resilience characteristics (themes) were identified: coping skills, cognitive flexibility, optimism, skill for facing fear, and social support. Participants with higher resilience scores generally described effective use of coping skills, cognitive flexibility, optimism, skills in facing fears, and social support to attain meaningful goals. In contrast, participants with lower resilience scores discussed passive coping strategies, cognitive rigidity, general pessimism, avoidance of activities due to fear, or social support limitations.

CONCLUSION

Coping skills, cognitive flexibility, optimism, skills for facing fear, and social support were identified as meaningful resilience characteristics for people with transtibial amputation in middle age or later. These characteristics can be targeted and enhanced using resilience interventions. Future research should consider these characteristics when designing and testing rehabilitation focused resilience interventions for people with TTA.

'It's . . . forward-focused': Experiences of a mobility clinic for people with limb loss

BACKGROUND

Mobility clinics are designed to extend gait and mobility training beyond rehabilitation programmes. No research has been undertaken into participants' experiences of attending these multidisciplinary, experience-based clinics. Research in this area is needed to ensure clinics meet intended goals, including understanding the motivation and experience of attendees. Insights may improve mobility clinics and inform strategies to encourage greater participation.

OBJECTIVES

To explore the motivation of people with limb loss to attend a mobility clinic, the experience of participation and their perception of the clinic's benefits.

STUDY DESIGN

Qualitative methodology, naturalistic enquiry.

METHODS

Semi-structured interviews were conducted with nine clinic attendees during the clinic. Interviews were transcribed verbatim, data thematically analysed and emergent themes underwent member checking.

RESULTS

Three themes emerged from the data: facing the challenge captured how participants' have adapted to amputation, valuing peers highlights the important role of peers in learning and support and improving mobility described the ongoing quest to improve mobility.

CONCLUSION

The mobility clinic was attractive to those who liked challenges and was an invaluable source of learning for those wishing to improve their mobility. Future clinics should ensure that peer education is supported, and activities cater for a range of skills and fitness levels.

CLINICAL RELEVANCE

Findings of this study indicate that those who attended the mobility clinic liked to challenge themselves. Participation with peers was an important source of learning and support. Those participants who had previously attended a mobility clinic reported improvements in their overall daily function.
