A review of user needs to drive the development of lower limb prostheses. J Neuroeng Rehabil 2022; 19:119. [PMCID: PMC9636812 DOI: 10.1186/s12984-022-01097-1] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 10/25/2022] [Indexed: 11/08/2022] Open
Abstract
Abstract
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).

PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2021; 9:e3920. [PMID: 35028257 PMCID: PMC8751770 DOI: 10.1097/gox.0000000000003920] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Accepted: 09/10/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND Outcomes after traumatic major lower extremity amputation (MLEA) have focused on surgical complications, despite the life-altering impact on patients. With advances in the surgical management of MLEA, a heightened need for consistent reporting of patient-centered outcomes (PCO) remains. This meta-analysis assesses articles for the prevalence and methods of PCO reporting among traumatic MLEA studies. METHODS An electronic database search was completed using Ovid MEDLINE for studies published between 2000 and 2020. Studies were included that reported any outcome of traumatic MLEA. Weighted means of outcomes were calculated when data were available. The prevalence of PCO was assessed in the categories of physical function, quality of life (QOL), psychosocial, and pain. Trends in PCO reporting were analyzed using Pearson's chi-squared test and analysis of variance when appropriate. RESULTS In total, 7001 studies were screened, yielding 156 articles for inclusion. PCO were evaluated in 94 (60.3%) studies; 83 (53.2%) reported physical function and mobility outcomes, 33 (21.2%) reported QOL and satisfaction measures, 38 (24.4%) reported psychosocial data, and 43 (27.6%) reported pain outcomes. There was no change in prevalence of PCO reporting when comparing 5-year intervals between 2000 and 2020 (P = 0.557). CONCLUSIONS Optimization of function and QOL following traumatic MLEA has become a cornerstone of surgical success; however, only 60% of studies report PCO, with no trend over the last two decades suggesting improvement. As healthcare progresses toward patient-centered care, this inconsistent means of reporting PCO calls for improved inclusion and standardization of instruments to assess function, QOL, and other patient-focused measures.

Abstract
BACKGROUND Amputation is a life-changing event accompanied by challenges for the affected person with time-dependent depression often used to quantify its level of impact on their psychological well-being. There are varied factors that contribute to this and its persistence. The aim of this study was to explore the experiences over time of people with diabetes and/or peripheral vascular disease following an amputation and the impact on their psychological well-being. OBJECTIVES To develop an understanding of the experience of living with an amputation and a chronic condition in order to help clinicians identify those in need of counselling support. STUDY DESIGN A qualitative study utilising an iterative approach in line with the philosophy of interpretive phenomenology. METHODS Six participants who had experienced a lower limb amputation associated with peripheral vascular disease/diabetes were interviewed on two occasions (baseline and 4 months). An interpretative phenomenological approach was utilised for both data collection and analysis. RESULTS For these participants, amputation was part of the chronology of their chronic disease. It was the individual's variable experience of health which impacted their psychological well-being rather than the length of time since amputation. CONCLUSIONS The multivariable experience of amputation means that individually tailored counselling/psychological support is recommended. CLINICAL RELEVANCE An understanding of how the experience of living with an amputation and a chronic condition may change over time will help clinicians to identify the ongoing need for counselling support.

Abstract
BACKGROUND A structured, multidisciplinary approach in the rehabilitation process after amputation is needed that includes a greater focus on the involvement of both (para)medics and prosthetists. There is considerable variation in prosthetic prescription concerning the moment of initial prosthesis fitting and the use of replacement parts. OBJECTIVES To produce an evidence-based guideline for the amputation and prosthetics of the lower extremities. This guideline provides recommendations in support of daily practice and is based on the results of scientific research and further discussions focussed on establishing good medical practice. Part 2 focuses on rehabilitation process and prosthetics. STUDY DESIGN Systematic literature design. METHODS Literature search in five databases and quality assessment on the basis of evidence-based guideline development. RESULTS An evidence-based multidisciplinary guideline on amputation and prosthetics of the lower extremity. CONCLUSION The best care (in general) for patients undergoing amputation of a lower extremity is presented and discussed. This part of the guideline provides recommendations for treatment and reintegration of patients undergoing amputation of a lower extremity and can be used to provide patient information. CLINICAL RELEVANCE This guideline provides recommendations in support of daily practice and is based on the results of scientific research and further discussions focussed on establishing good medical practice.

Abstract
Background Traumatic arm amputations can be treated with replantation or surgical formalization of the stump with or without subsequent prosthetic fitting. In the literature, many authors suggest the superiority of replantation. This systematic review compared available literature to analyze whether replantation is functionally and psychologically more profitable than formalization and prosthetic fitting in patients with traumatic arm amputation. Methods Functional outcome and satisfaction levels were recorded of patients with amputation levels below elbow, through elbow, and above elbow. Results Functional outcomes of 301 replantation patients and 172 prosthesis patients were obtained. In the replantation group, good or excellent functional scores were reported in 39% of above elbow, 55% of through elbow, and 50% of below elbow amputation cases. Nearly 100% of patients were satisfied with the replanted limb. In the prosthesis group, full use of the prosthesis was attained in 48% of above elbow and in 89% of below elbow amputation patients. Here, 29% of patients elected not to use the prosthesis for reasons including pain and functional superfluity. In both replantation patients and prosthesis wearers, a below elbow amputation yielded better functional results than higher amputation levels. Conclusions Replantation of a traumatically amputated arm leads to good function and higher satisfaction rates than a prosthesis, regardless of the objective functional outcome. Sensation and psychological well-being seem the two major advantages of replantation over a prosthesis. The current review of the available literature shows that in carefully selected cases replantation could be the preferred option of treatment.

The relationship between prosthesis use, phantom pain and psychiatric symptoms in male traumatic limb amputees. Compr Psychiatry 2015; 59:45-53. [PMID: 25764906 DOI: 10.1016/j.comppsych.2014.10.018] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2014] [Revised: 10/23/2014] [Accepted: 10/27/2014] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVES The purpose of this study was to identify psychiatric symptoms by comparing male patients with traumatic leg amputations (LAs) with healthy controls and to determine the association between these psychiatric symptoms and phantom pain and prosthesis use characteristics. METHODS One hundred four volunteers, 51 LA patients (group 1) and 53 healthy controls (group 2) were included. Demographic data including age, height, weight, time since amputation, duration of prosthesis use, and Satisfaction with Prosthesis Questionnaire scores were recorded. Phantom pain was measured a visual analog scale (VAS). Psychiatric symptoms were measured using the Symptom Checklist-90-R, Beck Depression Inventory, Pittsburgh Sleep Quality Index, Rosenberg Self-Esteem Scale, and State-Trait Anxiety Inventory. Correlations were determined between time since amputation, duration of prosthesis use and satisfaction with prosthesis questionnaire scores and psychiatric scale scores. RESULTS Amputee patients had higher phobic anxiety, state anxiety, trait anxiety and sleep disturbance scores (p<0.05) than the controls. No difference was determined in terms of psychiatric symptoms between the phantom pain and no phantom pain groups (p>0.05). There were significant negative correlations between time since amputation, duration of prosthesis use, duration of daily prosthesis use, and satisfaction with prosthesis questionnaire scores and psychiatric symptoms. CONCLUSIONS Apart from anxiety (state, trait or phobic) and disturbed sleep, other psychiatric symptoms in amputee patients undergoing lengthy prosthetic rehabilitation may not differ from those of healthy controls. The presence and severity of phantom pain appear to be unrelated to general psychiatric symptomatology. Length of time since amputation, length of prosthesis use, daily length of prosthesis use and prosthesis satisfaction are negatively correlated with general psychiatric symptoms. These characteristics must be borne in mind in psychiatric and prosthetic rehabilitation.

Abstract
Phantom limb pain (PLP) is a form of chronic neuropathic pain that responds poorly to treatment interventions derived from the neuroanatomic understanding of pain and analgesia. Several new psychological and behavioral treatments that have proven more effective have been explained by invoking neural plasticity as their mechanism of action. Other novel treatments that are based on an "energy medicine" model also appear to be quite effective, especially when addressing the psychological trauma of the amputation itself, a factor that is generally overlooked in the standard surgical approach to limb amputation. A speculative trauma/energy model for the etiology of PLP is proposed. This model is developed in some detail, and its utility in explaining several anomalous aspects of PLP, as well as the clinical efficacy of energy therapies, is outlined. This model is proposed as a step in the development of simple and effective energy/trauma treatment protocols for this widespread and largely treatment-resistant disorder.

Abstract
INTRODUCTION Lower limb amputation (LLA) is life-changing surgery. Shorter residual limbs are known to place greater physiological strain on patients than longer residual limbs; however, there is ongoing debate as to whether through-knee amputations are preferable to above-knee amputations. This analysis aims to resolve this question by systematically collecting and pooling published and unpublished data on this subject. METHODS An exhaustive search of Medline, Embase and Recal databases was made for outcome studies of patients with lower limb amputations following trauma. Studies concerned with amputations of the upper limb or foot and ankle were excluded as were papers reporting outcomes in a population of mixed trauma and non-trauma patients. Authors of studies published in the last 10 years were contacted for unpublished details. Patients were then divided, according to amputation height, into four groups: below-knee amputation (BKA), through-knee amputation (TKA), above-knee amputation (AKA) and bilateral amputation. The primary outcome measure was Physical Component Score (PCS) of the short-form-36 measure of quality of life and secondary outcomes were pain, employment, ability to walk 500m and proportion of time that prosthesis is worn. RESULTS As many as 27 studies were included, representing a total of 3105 patients, 1855 with a BKA, 104 with a TKA, 888 with an AKA and 258 bilateral amputees. There was progressive and significant lowering of PCS (worsening outcomes) as unilateral amputation height became more proximal from BKA to TKA and AKA. A significantly greater proportion of patients with a BKA or a TKA were able to walk 500m than those with an AKA or bilateral amputation (p=0.0035). However, patients with a TKA wore their prosthesis significantly less, and had significantly more pain than those with an AKA. CONCLUSION This study describes the impact of LLA of different levels on patients' lives. The results indicate that patients with a TKA have a better physical quality of life than those with an AKA and, therefore, support the surgical strategy of maintaining maximum length and performing TKA in preference to AKA, where possible.

Abstract
BACKGROUND The study aim was to determine the outcome, in relation to military service in UK military combat amputees. PATIENTS AND METHODS Casualties were assessed at mean 2.4 years after injury and graded by a Functional Activity Assessment (FAA) ranging from 1 (fully fit) to 5 (unfit all duties) to score vocational functional outcome. ISS were calculated and the patients were categorised as having unilateral or multiple amputations. The Short Form-36 Health Survey (SF-36) was completed. RESULTS Of the 52, 8 patients had left the forces by medical discharge, with 44 continuing to serve. 33 of the 44 had returned to work. 50 patients had FAA grades and were at least 7.6 months post-injury. No patients were graded as FAA1, 8 as FAA2, 18 as FAA3, 19 as FAA4 and 5 as FAA5. There was a trend for the FAA score to increase with injury severity, as measured by ISS i.e. vocational functional outcome was worse with more severe injuries, although this did not reach statistical significance (p=0.095). Multiple amputee patients had significantly higher FAA grades (p<0.001) and were all FAA 4 or 5. Of the 33 patients who had returned to work, 8 were FAA2, 12 FAA3 and 12 FAA4. The mean SF-36 scores for Physical Component Summary (PCS) increased significantly from 36.4 to 43.4 (p=0.001) with rehabilitation, while Mental Component Summary (MCS) was 53.0 and remained similar at 53.6 (p=0.987). MCS scores were similar in these patients to the normal population, 50 (SD 10). CONCLUSIONS This study is the first to report the outcomes, with regards to return to work, of the UK military amputees injured in Afghanistan and Iraq Soldiers are surviving more severe and complex injuries than before and the majority are able to return successfully to military work. SF-36 PCS scores improve significantly with rehabilitation, and while MCS scores remain constant, the initial assessments are comparable with a normal population.

Abstract
Post-Traumatic Stress Disorder has been identified as one of the most commonly occurring mental illnesses in combatants. This study was conducted to determine the prevalence of Post-Traumatic Stress Disorder among soldiers who had undergone amputation of a lower or an upper limb or sustained a spinal cord injury in the battlefield, and to compare the prevalence among these categories. The research presented seeks to increase the awareness of this condition among those treating war casualties so that appropriate treatment choices could be made to address them. The study was carried out in 2009 at a rehabilitation centre for combatants of war. Data were collected from 96 male army veterans between the ages of 18-49 years using a pre-tested self-administered questionnaire based on the Diagnostic and Statistical Manual of Mental Disorders, the Impact of Event Scale and the PTSD symptom scale. Soldiers with injuries sustained at least four weeks prior to the study were selected by a convenience sampling technique. Soldiers with multiple injuries, head injuries or those diagnosed with psychiatric disorders were excluded. The results revealed that 41.7% of the study population was compatible with the diagnosis of Post-Traumatic Stress Disorder. Within the three groups, 42.5% of the lower limb amputees, 33.3% of the upper limb amputees and 45.7% of the participants with spinal cord injury had symptoms compatible with Post-Traumatic Stress Disorder. There was no difference between the prevalence among the different injury categories considered. This study highlights the need to pay more attention in providing psychological care as a part of the overall health management of injured combatants. Early preparation of soldiers for stressors of war and screening for and proper management of Post-Traumatic Stress Disorder will improve the overall outcome of rehabilitation.
