Abstract
OBJECTIVES Individuals with lower-limb amputations (LLA) often have deficits in balance and community walking ability. As a result, people with LLA are often sedentary. The aim of this study was to explore perceptions of physical activity from the perspective of people with LLA. METHODS A qualitative descriptive study situated within an interpretive research paradigm was conducted. Semistructured interviews were held by telephone or in person with adults living with major LLAs recruited from rehabilitation hospitals and advertisements on social media. Individuals were included if they were age 18 years and older with a major LLA. Purposive sampling was used to ensure variation by sex, cause, and level of amputation. RESULTS Thirty-three people with LLA participated (22 men/11 women; median age 63 years). The majority of individuals had a unilateral, transtibial amputation (∼50% dysvascular LLA). Three main themes were developed to characterize participants' perceptions of physical activity: (1) physical activity is perceived as important but can be challenging after amputation; (2) physical activity has physical and mental health benefits; and (3) physical activity is a means to maintain independence and engagement in community and social life. CONCLUSIONS Obtaining the perspectives of individuals with LLA about physical activity helps us understand how they think about it, what motivates them, and how we can optimize physical activity levels. Future research is needed to evaluate the effectiveness of interventions to enhance physical activity in this population.

Johansson R, Jensen L, Barnett CT, Rusaw DF. Quantitative methods used to evaluate balance, postural control, and the fear of falling in lower limb prosthesis users: A systematic review. Prosthet Orthot Int 2023; 47:586-598. [PMID: 37318276 DOI: 10.1097/pxr.0000000000000250] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 04/23/2023] [Indexed: 06/16/2023]
Abstract
Problems with balance, postural control, and fear of falling are highly prevalent in lower limb prosthesis users, with much research conducted to understand these issues. The variety of tools used to assess these concepts presents a challenge when interpreting research outcomes. This systematic review aimed to provide a synthesis of quantifiable methods used in the evaluation of balance, postural control, and fear of falling in lower limb prosthesis users with an amputation level at or proximal to the ankle joint. A systematic search was conducted in CINAHL, Medline, AMED, Cochrane, AgeLine, Scopus, Web of Science, Proquest, PsycINFO, PsycArticles, and PubPsych databases followed by additional manual searching via reference lists in the reviewed articles databases. Included articles used quantitative measure of balance or postural control as one of the dependent variables, lower limb prosthesis users as a sample group, and were published in a peer-reviewed journal in English. Relevant assessment questions were created by the investigators to rate the assessment methods used in the individual studies. Descriptive and summary statistics are used to synthesize the results. The search yielded (n = 187) articles assessing balance or postural control (n = 5487 persons in total) and (n = 66) articles assessing fear of falling or balance confidence (n = 7325 persons in total). The most used test to measure balance was the Berg Balance Scale and the most used test to measure fear of falling was the Activities-specific Balance Confidence scale. A large number of studies did not present if the chosen methods were valid and reliable for the lower limb prosthesis users. Among study limitations, small sample size was common.

Abstract
INTRODUCTION AND IMPORTANCE Chronic calcaneal osteomyelitis is a challenging condition associated with high relapse rates, requiring a multidisciplinary approach and various therapeutic options for effective management. We report a very rare case of a pyogenic osteomyelitis of the os calcis presented as a bone abscess. CASE PRESENTATION A diabetic male patient presented with chronic osteomyelitis of the calcaneus in the form of bone abscess with a cavity of 6*5 cm. After pus evacuation and debridement of the cavity, gentamycin-impregnated polymethylmethacrylate cement was used to locally assist in controlling the infection and to assure mechanical support. Antibiogram-based oral antibiotic was administrated for 6 weeks. At final follow-up, the patient could walk without any assistance and was able to raise his body on the operated heel, with no signs of infection. CLINICAL DISCUSSION This case illustrates successful conservative surgical treatment of calcaneal abscess using antibiotic-impregnated cement for mechanical support and local infection control. CONCLUSION Incorporating antibiotic-impregnated cement into conservative foot surgeries for deeply embedded calcaneal abscesses provides effective infection control, mechanical support, and functional preservation, leading to successful treatment outcomes.

Abstract
This study aims to highlight recent research work on topics around prosthetic feet through a scientometric analysis and historical review. The most cited publications from the Clarivate Analytics Web of Science Core Collection database were identified and analyzed from 1 January 2000 to 31 October 2022. Original articles, reviews with full manuscripts, conference proceedings, early access documents, and meeting abstracts were included. A scientometric visualization analysis of the bibliometric information related to the publications, including the countries, institutions, journals, references, and keywords, was conducted. A total of 1827 publications met the search criteria in this study. The related publications grouped by year show an overall trend of increase during the two decades from 2000 to 2022. The United States is ranked first in terms of overall influence in this field (n = 774). The Northwestern University has published the most papers on prosthetic feet (n = 84). Prosthetics and Orthotics International has published the largest number of studies on prosthetic feet (n = 151). During recent years, a number of studies with citation bursts and burst keywords (e.g., diabetes, gait, pain, and sensor) have provided clues on the hotspots of prosthetic feet and prosthetic foot trends. The findings of this study are based on a comprehensive analysis of the literature and highlight the research topics on prosthetic feet that have been primarily explored. The data provide guidance to clinicians and researchers to further studies in this field.

Sawers A, Fatone S. After scaling to body size hip strength of the residual limb exceeds that of the intact limb among unilateral lower limb prosthesis users. J Neuroeng Rehabil 2023; 20:50. [PMID: 37098570 PMCID: PMC10131313 DOI: 10.1186/s12984-023-01166-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Accepted: 03/30/2023] [Indexed: 04/27/2023] Open
Abstract
BACKGROUND Hip muscles play a prominent role in compensating for the loss of ankle and/or knee muscle function after lower limb amputation. Despite contributions to walking and balance, there is no consensus regarding hip strength deficits in lower limb prosthesis (LLP) users. Identifying patterns of hip muscle weakness in LLP users may increase the specificity of physical therapy interventions (i.e., which muscle group(s) to target), and expedite the search for modifiable factors associated with deficits in hip muscle function among LLP users. The purpose of this study was to test whether hip strength, estimated by maximum voluntary isometric peak torque, differed between the residual and intact limbs of LLP users, and age- and gender-matched controls. METHODS Twenty-eight LLP users (14 transtibial, 14 transfemoral, 7 dysvascular, 13.5 years since amputation), and 28 age- and gender-matched controls participated in a cross-sectional study. Maximum voluntary isometric hip extension, flexion, abduction, and adduction torque were measured with a motorized dynamometer. Participants completed 15 five-second trials with 10-s rest between trials. Peak isometric hip torque was normalized to body mass × thigh length. A 2-way mixed-ANOVA with a between-subject factor of leg (intact, residual, control) and a within-subject factor of muscle group (extensors, flexors, abductors, adductors) tested for differences in strength among combinations of leg and muscle group (α = 0.05). Multiple comparisons were adjusted using Tukey's Honest-Difference. RESULTS A significant 2-way interaction between leg and muscle group indicated normalized peak torque differed among combinations of muscle group and leg (p < 0.001). A significant simple main effect of leg (p = 0.001) indicated peak torque differed between two or more legs per muscle group. Post-hoc comparisons revealed hip extensor, flexor, and abductor peak torque was not significantly different between the residual and control legs (p ≥ 0.067) but torques in both legs were significantly greater than in the intact leg (p < 0.001). Peak hip abductor torque was significantly greater in the control and residual legs than the intact leg (p < 0.001), and significantly greater in the residual than control leg (p < 0.001). CONCLUSIONS Our results suggest that it is the intact, rather than the residual limb, that is weaker. These findings may be due to methodological choices (e.g., normalization), or biomechanical demands placed on residual limb hip muscles. Further research is warranted to both confirm, expand upon, and elucidate possible mechanisms for the present findings; and clarify contributions of intact and residual limb hip muscles to walking and balance in LLP users.

SENSORS (BASEL, SWITZERLAND) 2023; 23:1880. [PMID: 36850475 PMCID: PMC9964846 DOI: 10.3390/s23041880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 02/01/2023] [Accepted: 02/06/2023] [Indexed: 06/18/2023]
Abstract
Amputation has a big impact on the functioning of patients, with negative effects on locomotion and dexterity. In this context, inertial measurement units represent a useful tool in clinical practice for motion analysis, and in the development of personalized aids to improve a patient's function. To date, there is still a gap of knowledge in the scientific literature on the application of inertial sensors in amputee patients. Thus, the aim of this narrative review was to collect the current knowledge on this topic and stimulate the publication of further research. Pubmed, Embase, Scopus, and Cochrane Library publications were screened until November 2022 to identify eligible studies. Out of 444 results, we selected 26 articles focused on movement analysis, risk of falls, energy expenditure, and the development of sensor-integrated prostheses. The results showed that the use of inertial sensors has the potential to improve the quality of life of patients with prostheses, increasing patient safety through the detection of gait alteration; enhancing the socio-occupational reintegration through the development of highly technologic and personalized prosthesis; and by monitoring the patients during daily life to plan a tailored rehabilitation program.

Abstract
PURPOSE There is a lack of high-quality evidence about the effects of exercise or physical activity interventions for adults with lower limb amputations (LLAs). A planning meeting involving stakeholders (i.e., people with LLA, community advocates, health care providers, researchers) was organized to identify key research priorities related to exercise and physical activity for people with LLAs. METHODS We used a collaborative prioritized planning process with a pre-meeting survey and 2-day virtual meeting that included: identification and prioritization of challenges or gaps; identification and consolidation of solutions; and action planning. This process integrated a modified Delphi approach, including anonymous feedback in two surveys. RESULTS Thirty-five stakeholders participated. Six challenges related to exercise and physical activity for people with LLA were prioritized. One solution was prioritized for each challenge. After consolidation of solutions, participants developed five research action plans for research including: developing an on-line interface; developing and evaluating peer-support programs to support physical activity; examining integration of people with LLA into cardiac rehabilitation; development and evaluation of health provider education; and determining priority outcomes related to physical activity and exercise. CONCLUSIONS This collaborative process resulted in an action plan for amputation research and fostered collaborations to move identified priorities into action.IMPLICATIONS FOR REHABILITATIONLower limb amputations impact mobility leading to lower levels of physical activity.There are research gaps in our understanding of the effects of exercise or physical activity interventions for adults with lower limb amputations.Through a collaborative planning process, participants prioritized research directions on physical activity and exercise for people with LLA to advance research in the field.Action plans for research focused on developing online resources, peer support, cardiac rehabilitation for people with LLA, health provider education and determining priority outcomes related to physical activity and exercise.

Abstract
Objective To explore the effectiveness of (active) lifestyle interventions for the health of people with a lower limb amputation in order to offer effective interventions during rehabilitation that may improve physical and psychosocial functioning of people with lower limb amputation. Data Sources PubMed, CINAHL and Embase were searched from inception to February 2021. Study Selection Inclusion criteria were (1) (quasi-)randomized controlled trial; (2) minimum of 10 participants with a lower limb amputation; (3) lifestyle intervention focusing on physical activity, smoking habits, alcohol use, nutrition, and/or stress management; (4) focus on health outcomes; (5) participants older than 18 years; (6) studies in Dutch, German, or English; and (7) primary research. Title, abstract, and full-text screening and quality assessment were performed by 2 independent assessors. Data Extraction Of 2460 studies identified, 13 studies were included in this review. Two studies were of moderate methodological quality, 2 studies were of medium quality, and 9 studies were of poor quality. Data Synthesis Lifestyle interventions in the included studies focused on physical activity and stress management. These interventions seemed effective for improving physical fitness, walking capacity, changes in body mass, quality of life, and intensity of physical activity. Conclusion Lifestyle interventions focusing on physical activity and stress management seem effective for improving physical and psychosocial functioning of people with a lower limb amputation. However, the findings should be interpreted with caution given the limited methodological quality of the included studies. Future research should evaluate the effectiveness of interventions on nutrition, smoking habits, and alcohol use and the effectiveness of combined interventions in people with a lower limb amputation.

Abstract
PURPOSE The purpose of this study was to explore the barriers and facilitators to physical activity from multiple stakeholder perspectives including individuals with LLA and health professionals. MATERIALS AND METHODS A qualitative descriptive study situated within an interpretive research paradigm was conducted. Semi-structured interviews were held with individuals with LLA recruited from rehabilitation hospitals in a metropolitan city in Canada. Health professionals with experience in amputation care were recruited from across Canada. Data were analysed using codebook thematic analysis. RESULTS Thirty-three individuals with LLA and eighteen health professionals participated. Six themes were generated which represent the perceived barriers and facilitators to physical activity. Themes including Informal and Formal Supports, Availability of and Access to Community Resources, and Fit and Function of the Prosthesis were perceived by many individuals as facilitators, while acting as a barrier for others depending on an individual's circumstances. CONCLUSIONS These findings provide us with a basis of understanding from which we can begin addressing barriers to physical activity for individuals with LLA, in support of developing patient-centred interventions and physical activity programs for this population. IMPLICATIONS FOR REHABILITATIONIrrespective of amputation etiology, individuals who have lower limb amputation experience several barriers to engaging in physical activity.Many system-level barriers to physical activity exist for people with lower limb amputation, which include lack of availability and access to community resources and specialised prostheses conducive to physical activity participation.A participatory approach engaging both patients and rehabilitation professionals can address the patient-provider discordance with respect to a patient's motivation and attitude towards physical activity participation by creating a supportive environment conducive to behaviour change.The development of future, patient-centered interventions, and physical activity programs for individuals with lower limb amputation must consider fear of falling as a prominent barrier to physical activity and devise potential strategies to address this barrier, by setting realistic and actionable goals.

Abstract
Background: The rapidly increasing use of wearable technology to monitor free-living ambulatory behavior demands to address to what extent the chosen outcome measures are representative for real-world situations. This scoping review aims to provide an overview of the purpose of use of wearable activity monitors in people with a Lower Limb Amputation (LLA) in the real world, to identify the reported outcome measures, and to evaluate to what extent the reported outcome measures capture essential information from real-world ambulation of people with LLA. Methods: The literature search included a search in three databases (MEDLINE, CINAHL, and EMBASE) for articles published between January 1999 and January 2022, and a hand-search. Results and conclusions: 98 articles met the inclusion criteria. According to the included studies’ main objective, the articles were classified into observational (n = 46), interventional (n = 34), algorithm/method development (n = 12), and validity/feasibility studies (n = 6). Reported outcome measures were grouped into eight categories: step count (reported in 73% of the articles), intensity of activity/fitness (31%), type of activity/body posture (27%), commercial scores (15%), prosthetic use and fit (11%), gait quality (7%), GPS (5%), and accuracy (4%). We argue that researchers should be more careful with choosing reliable outcome measures, in particular, regarding the frequently used category step count. However, the contemporary technology is limited in providing a comprehensive picture of real-world ambulation. The novel knowledge from this review should encourage researchers and developers to engage in debating and defining the framework of ecological validity in rehabilitation sciences, and how this framework can be utilized in the development of wearable technologies and future studies of real-world ambulation in people with LLA.

Deutsch JE, Gill-Body KM, Schenkman M. Updated Integrated Framework for Making Clinical Decisions Across the Lifespan and Health Conditions. Phys Ther 2022; 102:6497836. [PMID: 35079823 DOI: 10.1093/ptj/pzab281] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 09/16/2021] [Accepted: 10/26/2021] [Indexed: 11/13/2022]
Abstract
The updated Integrated Framework for Clinical Decision Making responds to changes in evidence, policy, and practice since the publication of the first version in 2008. The original framework was proposed for persons with neurological health conditions, whereas the revised framework applies to persons with any health condition across the lifespan. In addition, the revised framework (1) updates patient-centered concepts with shared clinical decision-making; (2) frames the episode of care around the patient's goals for participation; (3) explicitly describes the role of movement science; (4) reconciles movement science and International Classification of Function language, illustrating the importance of each perspective to patient care; (5) provides a process for movement analysis of tasks; and (6) integrates the movement system into patient management. Two cases are used to illustrate the application of the framework: (1) a 45-year-old male bus driver with low back pain whose goals for the episode of care are to return to work and recreational basketball; and (2) a 65-year-old female librarian with a fall history whose goals for the episode of care are to return to work and reduce future falls. The framework is proposed as a tool for physical therapist education and to guide clinical practice for all health conditions across the lifespan.

Abstract
The demand has increased for evidence regarding the effectiveness and value of prosthetic and orthotic rehabilitation interventions. Clinicians and managers are under pressure to provide treatment recommendations and demonstrate effectiveness through outcomes. It is often assumed that rehabilitation interventions, including the provision of custom-made and custom-fit orthotic and prosthetic devices, are beneficial to patients. Assessing the value of orthotic and prosthetic services has become more critical to continue to ensure equitable access to needed services. Health economics and outcomes research methods serve as tools to gauge the value of prosthetic and orthotic rehabilitation interventions. The purpose of this article is to provide an overview of the current need of health economics and outcomes research in orthotics and prosthetics, to introduce common economic methods that assist to generate real-world evidence, and to discusses the potential value of economic methods for clinicians and clinical practice.

Mobile App (WHEELS) to Promote a Healthy Lifestyle in Wheelchair Users With Spinal Cord Injury or Lower Limb Amputation: Usability and Feasibility Study. JMIR Form Res 2021; 5:e24909. [PMID: 34379056 PMCID: PMC8386360 DOI: 10.2196/24909] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Revised: 03/01/2021] [Accepted: 05/08/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Maintaining a healthy lifestyle is important for wheelchair users' well-being, as it can have a major impact on their daily functioning. Mobile health (mHealth) apps can support a healthy lifestyle; however, these apps are not necessarily suitable for wheelchair users with spinal cord injury or lower limb amputation. Therefore, a new mHealth app (WHEELS) was developed to promote a healthy lifestyle for this population. OBJECTIVE The objectives of this study were to develop the WHEELS mHealth app, and explore its usability, feasibility, and effectiveness. METHODS The WHEELS app was developed using the intervention mapping framework. Intervention goals were determined based on a needs assessment, after which behavior change strategies were selected to achieve these goals. These were applied in an app that was pretested on ease of use and satisfaction, followed by minor adjustments. Subsequently, a 12-week pre-post pilot study was performed to explore usability, feasibility, and effectiveness of the app. Participants received either a remote-guided or stand-alone intervention. Responses to semistructured interviews were analyzed using content analysis, and questionnaires (System Usability Score [SUS], and Usefulness, Satisfaction, and Ease) were administered to investigate usability and feasibility. Effectiveness was determined by measuring outcomes on physical activity, nutrition, sleep quality (Pittsburgh Sleep Quality Index), body composition, and other secondary outcomes pre and post intervention, and by calculating effect sizes (Hedges g). RESULTS Sixteen behavior change strategies were built into an app to change the physical activity, dietary, sleep, and relaxation behaviors of wheelchair users. Of the 21 participants included in the pilot study, 14 participants completed the study. The interviews and questionnaires showed a varied user experience. Participants scored a mean of 58.6 (SD 25.2) on the SUS questionnaire, 5.4 (SD 3.1) on ease of use, 5.2 (SD 3.1) on satisfaction, and 5.9 (3.7) on ease of learning. Positive developments in body composition were found on waist circumference (P=.02, g=0.76), fat mass percentage (P=.004, g=0.97), and fat-free mass percentage (P=.004, g=0.97). Positive trends were found in body mass (P=.09, g=0.49), BMI (P=.07, g=0.53), daily grams of fat consumed (P=.07, g=0.56), and sleep quality score (P=.06, g=0.57). CONCLUSIONS The WHEELS mHealth app was successfully developed. The interview outcomes and usability scores are reasonable. Although there is room for improvement, the current app showed promising results and seems feasible to deploy on a larger scale.

Foot Ankle Surg 2021; 27:598-605. [PMID: 32830053 DOI: 10.1016/j.fas.2020.07.014] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Revised: 07/11/2020] [Accepted: 07/31/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND Infected diabetic foot ulcers (DFU) complicated with calcaneal osteomyelitis are a real challenge for limb preservation. Very few alternatives to amputation are available, mainly the resection of a part or the totality of the calcaneal bone. Calcanectomies were advanced as limb-sparing procedures in patients with heel osteomyelitis. However, there is a lack of pooled quantitative evidence on their efficacy and complications. OBJECTIVES The present systematic review and meta-analysis was conducted to determine the primary outcome of healing rates following partial (PC) and total calcanectomies (TC) in treating calcaneal osteomyelitis due to diabetic heel ulcers. Additionally, secondary outcomes such as secondary TC following PC, secondary below knee amputation (BKA), mortality and the change in the ambulation status were analyzed. METHODS Medline, Scopus, Web of science, Cochrane Library and Google Scholar were searched since inception. All types of study design were included. Single case report studies and studies reporting osteomyelitis due to other etiologies than DFU were excluded. RESULTS Twenty studies met the inclusion criteria comprising 295 patients with 300 calcanectomies (270 PC and 30 TC). With a mean follow-up period of 29.3±17.7 months, the weighted results were as follows: a) the osteomyelitis healing rate was of 80% (95% CI=0.728 to 0.861, I2=48.3%), b) the rate of secondary total calcanectomy was of 5.4% (95% CI=0.022 to 0.097, I2=7.5%), c) the rate of secondary BKA was of 17.1% (95% CI=0.111 to 0.241, I2=50.6%) with no difference between subgroups of TC and PC, and d) the combined mortality rate of both calcanectomies was of 13.4% (95% CI=0.064 to 0.224, I2=73.6%); however, significant higher mortality was found following TC compared to PC (p<0.0001). CONCLUSION Partial and total calcanectomies were found to yield very good healing rates with acceptable complication frequencies. When compared to the reported outcomes of below and above-knee amputations in the literature, calcanectomies could be fairly considered as good alternatives to above ankle amputations.

[PMID: 33909881 DOI: 10.1093/ptj/pzab115] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2020] [Revised: 02/08/2021] [Accepted: 03/31/2021] [Indexed: 01/09/2023]
Abstract
OBJECTIVE After amputation, people with lower-limb loss (PLL) face challenges to regain their previous physical activity level. Assessing the scope of evidence regarding physical activity in PLL can identify sources of evidence and gaps within the literature that can influence amputation-related research, outcome assessment choices, and wellness activities. The purpose of this scoping review was to map the evidence regarding steps per day as a physical activity measure for PLL. Specific aims were to (1) identify research designs, (2) catalog population subgroups, (3) document steps per day measurement methods, and (4) provide descriptive data for steps per day in PLL. METHODS The MEDLINE, CINAHL, Embase, Web of Science, and AMED databases; and the Journal of Prosthetics and Orthotics archive were searched without language or time limits. Exclusion criteria included no PLL subjects, not peer-reviewed, and no direct step count measure. Inclusion criteria allowed any sample size, nonprosthetic use, and self-reported step count. As a scoping review, only descriptive statistics were compiled, and no methodologic quality assessment was performed. RESULTS Twenty-one articles using crossover (8), cohort (4), cross-section (8), and case-study (1) designs were included that reported accelerometer (19) or pedometer (2) data. Studies often mixed amputation etiologies (15/21) and most (13/21) excluded transfemoral amputations. Studies primarily examined people with transtibial amputations (81.2%) and people at independent community walking levels (Medicare functional classifications: K3 = 49.2%, K4 = 36.3%). All 21 studies had fewer than 100 participants, and overall included 515 subjects (343, 66.6% male), mean (SD) age 53.2 (22.1) years. Mean (SD) number of pooled steps per day for PLL was 5087 (2998): 5929 (3047) for transtibial amputations and 3553 (2030) for transfemoral amputations. CONCLUSIONS Most PLL have low activity levels compared with the 10,000 steps per day generally recommended or 6000 common in people with diabetes. Research with larger samples, defined subgroups, and data along the recovery continuum would enhance knowledge of physical activity level in PLL. IMPACT This scoping review has identified gaps in the research related to steps per day as a measure of physical activity in people with lower-limb loss to guide future research. LAY SUMMARY People with lower-limb loss take fewer steps per day than suggested for general health. Increasing steps per day may be a useful goal for this population, and this study is a first step in improving knowledge of physical activity levels in people with lower-limb loss.

Abstract
BACKGROUND Physical function is a common target of rehabilitation intervention to improve disability and physical activity after dysvascular lower-limb amputation (LLA); yet, the influence of psychosocial factors on physical activity is unclear. OBJECTIVE To identify psychosocial factors with potential to influence clinically relevant measures of physical activity, physical function, and disability in light of participants' narratives. DESIGN Convergent mixed-methods. SETTING General community. PARTICIPANTS Twenty participants with dysvascular LLA were enrolled if their most recent LLA was at least 1 year prior, they were ambulating independently with a prosthesis, and were between 45 and 88 years old. INTERVENTION Not applicable. MAIN OUTCOME MEASURES Quantitative data included physical activity (activPAL; steps/d), physical function (Timed Up-and-Go; TUG), and disability (World Health Organization Disability Assessment Schedule 2.0; WHODAS 2.0). Qualitative data were collected via semistructured interviews. RESULTS Higher steps/d was moderately correlated with better TUG time (r = -.58, P < .01), but was not correlated with WHODAS 2.0 score (r = -0.18; P > .10). Qualitative analysis of interviews, using an inductive, team-based, phenomenological approach, identified four themes: (1) perceptions of their prosthesis, (2) fear during mobility, (3) influence of LLA on life activities, and (4) positive outlook within social interactions. Mixed-methods analysis used an iterative approach to interpret and describe how psychosocial factors influence physical activity in four exemplar cases. CONCLUSIONS Physical activity in people with dysvascular LLA results from an interaction among perceptions of their prosthesis, fear during mobility, influence of LLA on life activities, and positive outlook within social interactions. The overlapping nature of these themes suggests that interventions targeting psychosocial factors may be associated with improved physical activity, physical function, and subsequent disability after dysvascular LLA.

Abstract
BACKGROUND Ambulatory individuals with lower-limb amputation perform a variety of locomotor activities, but the step count distribution of these activities is unknown. OBJECTIVE To describe a novel method for activity monitoring and to use it to count steps taken while walking straight ahead on level ground, turning right and left, up and down stairs, and up and down ramps. STUDY DESIGN This is an observational study. METHODS A portable instrument to record leg motion was placed on or inside the prosthetic pylon of 10 individuals with unilateral transtibial amputations. Participants first walked a defined course in a hospital environment to train and validate a machine learning algorithm for classifying locomotor activity. Participants were then free to pursue their usual activities while data were continuously collected over 1-2 d. RESULTS Overall classification accuracy was 97.5% ± 1.5%. When participants were free to walk about their home, work, and community environments, 82.8% of all steps were in a straight line, 9.0% were turning steps, 4.8% were steps on stairs, and 3.6% were steps on ramps. CONCLUSION A novel activity monitoring method accurately classified the locomotion activities of individuals with lower-limb amputation. Nearly 1 in 5 of all steps taken involved turning or walking on stairs and ramps.

Abstract
The L Test is a clinical mobility test used in patients after lower limb amputation. To assess dynamic balance, it should be performed with fast walking speed. Its measurement properties in the initial prosthetic training phase are not known yet. The objective of the study was to establish intra- and interrater reliability, concurrent and discriminant validity, minimal detectable change, effect size between the rehabilitation time points and ceiling effect of the L Test with fast walking speed in patients after lower limb amputation in initial prosthetic training phase. The study included 36 inpatients aged 19-86 years who were provided with a prosthesis for the first time. They were assessed repeatedly with the L Test, Ten-meter Walk Test and 6-min Walk Test. The intra- (ICC3, k = 0.94) and interrater reliability (ICC2, k = 0.96) of the L Test were excellent. Correlations with the walking tests were very good (r = 0.75-0.86). Regression analysis with respect to the level of lower limb amputation showed a linear relationship with other variables (R2 = 0.55). Influences of age, cause of lower limb amputation and walking aid were statistically significant. The L Test was responsive to change after two weeks of prosthetic training (Cohen's d = 1.21). No ceiling effect was identified. The L Test with fast walking speed is a feasible, reliable, valid, and responsive measure of basic mobility skills in patients after lower limb amputation in the initial prosthetic training phase.

Abstract
OBJECTIVE The objectives of this study were to describe sitting, standing, and stepping patterns for people with lower limb amputation (LLA) and to compare sitting, standing, and stepping between people with dysvascular LLA and people with traumatic LLA. METHODS Participants with dysvascular or traumatic LLA were included if their most recent LLA was at least 1 year earlier, they were ambulating independently with a prosthesis, and they were between 45 and 88 years old. Sitting, standing, and stepping were measured using accelerometry. Daily sitting, standing, and stepping times were expressed as percentages of waking time. Time spent in bouts of specified durations of sitting (<30, 30-60, 60-90, and >90 minutes), standing (0-1, 1-5, and >5 minutes), and stepping (0-1, 1-5, and >5 minutes) was also calculated. RESULTS Participants (N = 32; mean age = 62.6 [SD = 7.8] years; 84% men; 53% with dysvascular LLA) spent most of the day sitting (median = 77% [quartile 1 {Q1}-quartile 3 {Q3} = 67%-84%]), followed by standing (median = 16% [Q1-Q3 = 12%-27%]) and stepping (median = 6% [Q1-Q3 = 4%-9%]). One-quarter (median = 25% [Q1-Q3 = 16%-38%]) of sitting was accumulated in bouts of >90 minutes, and most standing and stepping was accrued in bouts of <1 minute (standing: median = 42% [Q1-Q3 = 34%-54%]; stepping: median = 98% [Q1-Q3 = 95%-99%]). Between-etiology differences included proportion of time sitting (traumatic: median = 70% [Q1-Q3 = 59%-78%]; dysvascular: median = 79% [Q1-Q3 = 73%-86%]) and standing (traumatic: median = 23% [Q1-Q3 = 16%-32%]; dysvascular: median = 15% [Q1-Q3 = 11%-20%]). CONCLUSION Participants had high daily volumes of long durations of sitting. Further, these individuals accumulated most physical activity in bouts of <1 minute. IMPACT High levels of sedentary behavior and physical inactivity patterns may place people with LLA at greater mortality risk relative to the general population. Interventions to minimize sedentary behaviors and increase physical activity are potential strategies for improving poor outcomes of physical therapy after LLA.

Abstract
OBJECTIVE The objective was to assess the impact of a prosthesis and the timing of prosthesis receipt on total direct healthcare costs in the 12-mo postamputation period. DESIGN Data on patients with lower limb amputation (n = 510) were obtained from a commercial claims database for retrospective cohort analysis. Generalized linear multivariate modeling was used to determine differences in cost between groups according to timing of prosthesis receipt compared with a control group with no prosthesis. RESULTS Receipt of a prosthesis between 0 and 3 mos post lower limb amputation yielded a reduced total cost by approximately 0.23 in log scale within 12 mos after amputation when compared with the no-prosthesis group. Despite the included costs of a prosthesis, individuals who received a prosthesis either at 4-6 mos postamputation or 7-9 mos postamputation incurred costs similar to the no-prosthesis group. CONCLUSION Earlier receipt of a prosthesis is associated with reduced spending in the 12 mos postamputation of approximately $25,000 compared with not receiving a prosthesis. The results of this study suggest that not providing or delaying the provision of a prosthesis increases costs by about 25%.

Abstract
Purpose of review To summarize outcome measurement research among adults with lower-limb loss (LLL) for clinicians. Recent findings Houghton Scale, Prosthetic Evaluation Questionnaire-mobility subscale (PEQ-m), Prosthetic Limb Users Survey of Mobility (PLUS-M™), Activities-Specific Balance Confidence Scale (ABC), Amputee Mobility Predictor (AMP), Comprehensive High-Level Activity Mobility Predictor, Four Square Step Test (FSST), Narrowing Beam Walking Test (NBWT), L Test, 10 Meter Walk Test (10MWT), and 6 Minute Walk Test (6MWT) are appropriate for evaluating individual patient changes post-LLL. Post-LLL, Socket Comfort Score, Patient-Specific Functional Scale, Patient-Reported Outcomes Measurement Information System 29-Item Profile, Timed Up and Go, and 2 Minute Walk Test may be more appropriate for evaluating groups. Minimal detectable change is available for 15/20 reviewed measures. Many measures differ between mobility levels. Summary Quick, reliable measures for evaluating patient functional change include ABC, PEQ-m, PLUS-M™, FSST, and L Test; when resources allow, NBWT, 10MWT, 6WMT and AMP may be considered.

Technology for monitoring everyday prosthesis use: a systematic review. J Neuroeng Rehabil 2020; 17:93. [PMID: 32665020 PMCID: PMC7362458 DOI: 10.1186/s12984-020-00711-4] [Citation(s) in RCA: 37] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Accepted: 06/23/2020] [Indexed: 01/08/2023] Open
Abstract
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.

Disabil Rehabil 2019; 41:3141-3150. [PMID: 30261758 PMCID: PMC6437000 DOI: 10.1080/09638288.2018.1492031] [Citation(s) in RCA: 29] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2017] [Revised: 05/21/2018] [Accepted: 06/19/2018] [Indexed: 10/28/2022]
Abstract
Purpose: Identifying factors associated with physical activity after dysvascular lower limb amputation (LLA) could provide targets for improving rehabilitation outcomes. The purpose of this meta-synthesis was to identify modifiable factors that may influence physical activity after LLA, a condition characterized by amputation in the setting of older age, diabetes mellitus (DM), and/or peripheral artery disease (PAD).Methods: A systematic search of the literature identified qualitative studies exploring the perceptions of physical activity in people with lower limb amputation, older age, DM, or PAD. Qualitative rigor was assessed using the McMaster University's Guidelines for Qualitative Review. Meta-synthesis was undertaken to analyze the findings of included studies.Results: Fourteen studies of variable methodological quality were included for analysis. Three overarching factors that may influence physical activity after LLA emerged: 1) educational experiences and motivation, 2) support and self-efficacy, and 3) special concerns after lower limb amputation (e.g., prosthesis, equipment, and environment).Conclusions: Physical activity after LLA is influenced by relationships among health understanding, motivation, support, and self-efficacy in the presence of disability. Themes from this meta-synthesis can be used to develop and test behavior-based interventions to improve physical activity after LLA.Implications for rehabilitationPhysical activity participation after dysvascular lower limb amputation is complicated by the presence of chronic conditions, severe disability, and unaddressed psychosocial factors.Addressing a patient's self-efficacy, social support, motivation, and understanding during physically focused rehabilitation may improve participation in physical activity after dysvascular lower limb amputation.Rehabilitation professionals can address self-efficacy, motivation, and understanding by using collaborative, empathetic communication strategies known to enhance a patient's sense of support.

Abstract
BACKGROUND Regular moderate-to-vigorous-intensity physical activity results in health benefits in people with diabetes. No study has observed the moderate-to-vigorous-intensity physical activity typically performed by people with diabetes-related foot ulcers (DFU) in their everyday free-living environments. We observed the bouts, and accumulated time, spent doing moderate-to-vigorous-intensity physical activity in cases with DFU compared with diabetes-related peripheral neuropathy (DPN) and diabetes (DM) controls over a one-week period. METHODS This was a secondary analysis of a cross-sectional case-control study. Participants wore a multisensor device for >5 days (>22 hours per day). Primary outcomes included the number, duration (minutes) and intensity (metabolic equivalent tasks [METs]) of bouts of moderate-to-vigorous-intensity physical activity (defined as at least >3 METs for >10 consecutive minutes). Secondary outcomes included the total accumulated times spent doing moderate-to-vigorous-intensity physical activity (>3 METs) and doing sedentary-intensity activity (<1.5 METs). DFU subgroups with minor amputations and nonremovable offloading devices were also analyzed. RESULTS Overall, 15 DM, 23 DPN, and 27 DFU participants were included. All groups recorded similar low median daily numbers (0.33, 0.29, 0.25 numbers, respectively), duration (15, 17, 14 minutes), and intensity of daily bouts of moderate-to-vigorous-intensity physical activity (4.1, 4.3, 3.9 METs) (all, P > .1). Median accumulated daily time spent doing moderate-to-vigorous-intensity physical activity was also similar (40, 37, 36 minutes; P > .8). Those with DFU had more mean accumulated daily time spent doing sedentary-intensity activity (796 minutes) compared to DPN (720 minutes; P < .05), but not compared to DM (728 minutes; P < .08). DFU subgroups with minor amputations had more median accumulated daily time spent doing moderate-to-vigorous-intensity physical activity (66, 28 minutes; P < .05) and less mean time doing sedentary-intensity activity (745, 837; P < .05) than those without amputations. CONCLUSIONS People with DFU performed similar low numbers of daily bouts of moderate-to-vigorous-intensity physical activity to controls, but spend more time doing sedentary-intensity activities. Interventions that gradually increase the moderate-to-vigorous-intensity physical activity in people with DFU should be investigated.

Abstract
Introduction: Calcaneal osteomyelitis is an uncommon and challenging condition. In this systematic review we aim to analyse the outcomes from concomitant use of bone debridement and soft tissue management for patients diagnosed with calcaneal osteomyelitis. Materials & Methods: A complete computerised and comprehensive literature search of Pubmed and Cochrane database was undertaken from January 2000 to October 2018. During the review, studies were screened for information about the surgical and antimicrobial treatment, the complications, the reinfection rate and the functional outcome of patients with calcaneal osteomyelitis. Results: Of the 20 eligible studies included, seven (35%) described bone treatment only, six (30%) soft tissue treatment only, five (25%) soft tissue and bone treatment, and two (10%) focused on prognostic factors and differences in outcomes between diabetic and non-diabetic patients. In the studies with bone treatment only, infection recurrence ranged from 0 to 35% and the amputation rate from 0 to 29%. If soft tissue coverage was also needed, both the reinfection rate and amputation rate ranged from 0 to 24%. Studies presenting the functional status generally showed preservation or even improvement of the preoperative ambulatory status. Conclusion: Calcaneal osteomyelitis is difficult to treat. A multidisciplinary approach involving orthopaedic surgeons, plastic surgeons and infectious disease physicians is preferred. The heterogenicity of studies has hindered the development of agreed treatment protocols, which would be useful in clinical practice.

Abstract
BACKGROUND Surgical procedures for calcaneal osteomyelitis are partial calcanectomy (PC), total calcanectomy (TC), and below-knee amputation (BKA). With calcaneal osteomyelitis, limb-saving surgery was described to have secondary BKA rates of 4% to 20%, while secondary amputation rates after BKA are unknown. The aim of this study was to describe and compare overall revision and secondary amputation rates for each surgical option in our institution's cohort and to identify risk factors for secondary amputation. METHODS Fifty patients treated between 2002 and 2017 were included. Revisions, secondary amputations, and possible risk factors for secondary amputation and overall revision were statistically analyzed. RESULTS Minor revisions rates were 57.1% in PCs, 100% in TCs, and 27.8% in BKAs. Secondary amputation was performed in 28.6% of the PCs, in 50% of the TCs, and in 5.6% of the BKAs. No statistically significant differences between overall revision and secondary amputation rates were found. C-reactive protein values greater than 5 mg/L at the index procedure were significantly associated with overall revision while we could not identify risk factors for secondary amputation. CONCLUSION This study represents the largest group of patients treated for calcaneal osteomyelitis in the literature. In limb-preserving surgical options, secondary BKA rates are higher than previously known. Primary BKA is a procedure with a low reamputation rate of 5.6%. PC can be considered, with 28.6% needing more proximal amputation. In TC, all patients underwent revision surgery and 50% had to undergo secondary BKA. Therefore, we hesitate to consider total calcanectomy as a surgical option in calcaneal osteomyelitis anymore. LEVEL OF EVIDENCE Level IV, case series.

Abstract
BACKGROUND People with dysvascular lower limb amputation (LLA) achieve one-third of the recommended steps per day and experience severe disability. Although physical function improves with rehabilitation after dysvascular LLA, physical activity remains largely unchanged, and factors contributing to limited daily step count are unknown. OBJECTIVES To identify factors that contribute to daily step count after dysvascular LLA. DESIGN Cross-sectional, secondary data analysis. SETTING Outpatient rehabilitation facilities. PARTICIPANTS Fifty-eight patients with dysvascular major LLA (age: 64 ± 9 years, body mass index: 30 ± 8 kg/m2 , male: 95%, transtibial LLA: 95%). METHODS Data were collected by a blinded assessor after dysvascular LLA. Candidate explanatory variables included (1) demographics, (2) LLA characteristics, (3) comorbidities and health behaviors, and (4) physical function. Variables with univariate associations with log steps/day (transformed due to non-normality) were included in a multiple linear regression model using backward elimination to identify factors that explained significant variability in log steps/day. PRIMARY OUTCOME MEASURE The primary outcome, daily step count, was measured with accelerometer-based activity monitors worn by participants for 10 days. RESULTS Participants took an average (± SD) of 1450 ± 1309 steps/day. After backward elimination, the final model included four variables explaining 62% of the overall daily step count (P < .0001): 2-minute walk distance (32%), assistive device use (11%), cardiovascular disease (10%), and pre-amputation walking time (11%). CONCLUSIONS Average daily step count of 1450 steps/day reflects the lowest category of sedentary behavior. Physical function, cardiovascular disease, and pre-amputation walking time explain 62% of daily step count after dysvascular LLA. Although physical rehabilitation commonly focuses on improving physical function, interventions to increase daily step count after dysvascular LLA should also consider chronic disease and health behaviors that predate LLA.

Abstract
Background The use of mobile devices in clinical research has advanced substantially in recent years due to the rapid pace of technology development. With an overall aim of informing the future use of mobile devices in interventional clinical research to measure primary outcomes, we conducted a systematic review of the use of and clinical outcomes measured by mobile devices (mobile outcomes) in observational and interventional clinical research. Method We conducted a PubMed search using a range of search terms to retrieve peer-reviewed articles on clinical research published between January 2010 and May 2016 in which mobile devices were used to measure study outcomes. We screened each publication for specific inclusion and exclusion criteria. We then identified and qualitatively summarized the use of mobile outcome assessments in clinical research, including the type and design of the study, therapeutic focus, type of mobile device(s) used, and specific mobile outcomes reported. Results The search retrieved 2,530 potential articles of interest. After screening, 88 publications remained. Twenty-five percent of the publications (n = 22) described mobile outcomes used in interventional research, and the rest (n = 66) described observational clinical research. Thirteen therapeutic areas were represented. Five categories of mobile devices were identified: (1) inertial sensors, (2) biosensors, (3) pressure sensors and walkways, (4) medication adherence monitors, and (5) location monitors; inertial sensors/accelerometers were most common (reported in 86% of the publications). Among the variety of mobile outcomes, various assessments of physical activity were most common (reported in 74% of the publications). Other mobile outcomes included assessments of sleep, mobility, and pill adherence, as well as biomarkers assessed using a mobile device, including cardiac measures, glucose, gastric reflux, respiratory measures, and intensity of head-related injury. Conclusion Mobile devices are being widely used in clinical research to assess outcomes, although their use in interventional research to assess therapeutic effectiveness is limited. For mobile devices to be used more frequently in pivotal interventional research – such as trials informing regulatory decision-making – more focus should be placed on: (1) consolidating the evidence supporting the clinical meaningfulness of specific mobile outcomes, and (2) standardizing the use of mobile devices in clinical research to measure specific mobile outcomes (e.g., data capture frequencies, placement of device). To that aim, this manuscript offers a broad overview of the various mobile outcome assessments currently used in observational and interventional research, and categorizes and consolidates this information for researchers interested in using mobile devices to assess outcomes in interventional research.
