Cardiorespiratory fitness in persons with lower limb amputation.

The aim of this study is to gain insight in the cardiorespiratory fitness of persons with lower limb amputation (LLA) during rehabilitation, and in potential factors influencing their cardiorespiratory fitness. We performed a retrospective cohort study using data from cardiopulmonary exercise tests. Included participants were adults with LLA. Main outcome was cardiorespiratory fitness expressed as O 2 peak (ml/min/kg) and was directly determined using breath-by-breath gas analysis. O 2 peak was compared to reference values for able-bodied controls. Multivariate regression analysis was performed to investigate potential factors related to O 2 peak in persons with LLA. Potential factors were age, BMI adjusted, gender, level of amputation, aetiology of amputation, unilateral/bilateral, type of ergometry and use of beta blockers. Data of 74 participants with LLA are presented; 84% male (n = 62), mean age 58.9 (SD 11.6), mean BMI 26.7 (SD 5.6), 44 participants have a LLA above the knee, 30 below the knee. Overall O 2 peak was lower in persons with LLA compared to reference values for able-bodied controls, with mean O 2 peak for the total LLA group of 14.6 ±â€…4.1 ml/kg/min. In the multivariate regression analysis, only age was a significant predictor for lower O 2 peak (regression coefficient: -0.15, 95% CI [0.23-0.069], r 2  = 0.166). These results indicate that the cardiorespiratory fitness in persons with LLA is low, while they actually need more energy to walk and perform other daily activities. Cardiorespiratory fitness is not closely associated with the analysed demographic or clinical factors and will have to be determined on an individual basis for use in daily practice.

A scoping review on nutritional intake and nutritional status in people with a major dysvascular lower limb amputation.

PURPOSE: To systematically review literature on nutritional intake, nutritional status and nutritional interventions, and to study their association with short- and long-term clinical outcomes in people with a major dysvascular lower limb amputation. METHODS: PubMed, Ovid, CINAHL, and The Cochrane Library were searched. Studies were included if nutritional intake, nutritional status, or nutritional interventions in people with a major dysvascular lower limb amputation were analyzed. RESULTS: Of the 3038 unique papers identified, 30 studies were included. Methodological quality was moderate (1 study) or weak (29 studies). Limited information was available on nutritional intake (2 studies) and nutritional interventions (1 study). Nutritional intake and nutritional status were assessed by diverse methods. The percentage of people with a poor nutritional status ranged from 1% to 100%. In some studies, measures of poor nutritional status were associated with adverse short- and long-term clinical outcomes. CONCLUSIONS: The percentage of people with a poor nutritional status is inconclusive in the major dysvascular lower limb amputation population, because of the heterogeneity of the assessment methods used. Some included studies reported a negative association between poor nutritional status and clinical outcomes. However, these results should be interpreted with caution, because of the limited quality of the studies available. Studies high in methodological quality and high in hierarchy of evidence are needed.IMPLICATIONS FOR REHABILITATIONThe proportion of people with a poor nutritional status in the major dysvascular lower limb amputation population is inconclusive.Poor nutritional status seems to affect clinical outcomes negatively.More uniformity in assessment of malnutrition in the major dysvascular lower limb amputation population is needed.

Perceptions, Experiences, Barriers and Facilitators Regarding Nutritional Intake of Patients with Chronic Limb Threatening Ischemia: A Qualitative Study.

BACKGROUND: Patients with chronic limb threatening ischemia (CLTI) are at high risk for amputation and other cardiovascular adverse events. Nutrition-related symptoms and malnutrition are common in the CLTI population, and lead to worse clinical outcomes. Understanding of the factors influencing nutritional intake is required to determine whether optimization of nutritional intake in this population requires interventions. Therefore, this study aimed to describe perceptions and experiences on nutrition of patients with CLTI, and to identify perceived barriers and facilitators influencing their nutritional intake. METHODS: In this phenomenological qualitative study, individual semi-structured, face-to-face interviews were conducted with patients with CLTI who lived independently. Interviews were transcribed verbatim, and reflexive thematic analysis was performed. RESULTS: Twelve participants were interviewed. Five themes were generated: (1) lack of nutritional risk perception, (2) role of nutrition for health, functioning, and surviving, (3) multiple factors influencing nutritional intake, (4) limited nutritional advice, and (5) no intention to change current nutritional intake. CONCLUSIONS: Patients with CLTI perceive nutritional intake as a necessity to survive and function. Patients express limited risk perception regarding adequate nutritional intake and undernutrition. Nutritional intake is mainly based on non-health-related factors, as habits and taste, and multiple barriers hinder nutritional intake. Patients received no or only limited nutritional advice. Together this leads to an expressed lack of intention to change nutritional intake. Findings of this study stress the urgency for patient-centered nutritional support, to increase nutrition-related knowledge and motivation, to prevent or treat undernutrition, and may improve clinical outcomes in patients with CLTI.

Surgical Techniques of, and Outcomes after, Distal Muscle Stabilization in Transfemoral Amputation: A Systematic Review and Narrative Synthesis.

BACKGROUND: Distal muscle stabilization, such as myodesis (suturing muscles to bone) or myoplasty (suturing agonistic-antagonistic muscles together), can aid residual limb stabilization, provide a good soft-tissue covering, and increase rehabilitation potential. However, surgical practice varies due to scant clinical data. The aim of this review is to summarize and evaluate the literature regarding techniques and associated outcomes of distal muscle stabilization in transfemoral amputation (TFA). METHODS: A systematic review and narrative synthesis was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Resources, including observational studies, nonobservational scientific papers, conference proceedings, and textbooks, detailing techniques of TFA distal muscle stabilization were identified from standard medical repositories and library search. A supplementary search of YouTube and Google was undertaken to identify additional resources. Quality assessment was undertaken using Risk Of Bias In Nonrandomized Studies-of Interventions; Authority, Accuracy, Coverage, Objectivity, Date, Significance; and modified-Discern tools. RESULTS: Forty seven resources were identified, including 17 journal articles, 17 textbooks, 5 educational websites/eBooks, 5 videos, 2 online presentations, and 1 webpage. Thirty seven described myodesis, 11 described myoplasty, and 6 described closure without distal muscle stabilization. Eight observational studies presented outcome data for 302 TFAs. No studies comparing closure with or without distal muscle stabilization were identified. All papers describing myodesis secured the adductors to the femur, and most also secured the quadriceps and/or hamstrings to this complex. Number of femoral drill holes varied from 1 to 6. Early wound complications occurred in 17% of amputations, whereas myodesis failure occurred in 9.5%. Prosthetic fitting rates were 73% and, where reported, 100% of patients maintained neutral femoral alignment. CONCLUSIONS: Distal muscle stabilization, particularly myodesis, is a commonly described technique for TFA, although operative techniques are heterogenous. There is a paucity of outcome data, and no studies comparing it to closures without distal muscle stabilization. However, these low-quality data suggest wound healing rates are equivalent to TFA without distal muscle stabilization while demonstrating improvement to patients' rehabilitation potential.

LONG-STANDING COMPLEX REGIONAL PAIN SYNDROME-TYPE I: PERSPECTIVES OF PATIENTS NOT AMPUTATED.

Objective: Complex Regional Pain Syndrome type I (CRPS-I) is an often intractable regional pain syndrome, usually affecting limbs in which amputation may be a final resort. Not all patients are suited for amputation.This retrospective case series with explorative interviews aims to gain insight in the quality of life in those who have been denied an amputation and their functioning with CRPS-I. Patients and methods: Between 2011 and 2017, 37 patients were denied an amputation. Participants were interviewed regarding quality of life, treatments received since their outpatient clinic visit and their experiences at our outpatient clinic. Results: A total of 13 patients participated. Most patients reported improvements in pain, mobility and overall situation. All patients received treatments after being denied an amputation, with some reporting good results. Many felt they had no part in decision making. Of the 13 participants 9 still had an amputation wish. Our participants scored worse in numerous aspects of their lives compared with patients with an amputation from a previous CRPS-I study of us. Conclusion: This study shows that amputation should only be considered after all treatments have been tried and failed, since most participants reported improvements in aspects of their functioning over time.

Lisfranc and Chopart amputation: A systematic review.

BACKGROUND: Lisfranc and Chopart amputations are historically controversial procedures. To obtain evidence for the pros and cons we performed a systematic review to analyze wound healing, the need for re-amputation at a higher level, and ambulation after a Lisfranc or Chopart amputation. METHODS: A literature search was performed in 4 databases (Cochrane, Embase, Medline, and PsycInfo), using database-specific search strategies. Reference lists were studied to include relevant studies that were missed in the search. Of the 2881 publications found, 16 studies could be included in this review. Excluded publications concerned editorials, reviews, letters to the editor, no full text available, case reports, not meeting the topic, and written in a language other than English, German, or Dutch. RESULTS: Failed wound healing occurred in 20% after Lisfranc amputation, in 28% after modified Chopart amputation, and 46% after conventional Chopart amputation. After Lisfranc amputation, 85% of patients were able to ambulate without prosthesis for short distances, and after modified Chopart 74%. After a conventional Chopart amputation, 26% (10/38) had unlimited household ambulation. CONCLUSIONS: The need for re-amputation because wound healing problems occurred most frequently after conventional Chopart amputation. All 3 types of amputation levels do, however, provide a functional residual limb, with the remaining ability to ambulate without prosthesis for short distances. Lisfranc and modified Chopart amputations should be considered before proceeding to a more proximal level of amputation. Further studies are needed to identify patient characteristics to predict favorable outcomes of Lisfranc and Chopart amputations.

User-relevant factors influencing the prosthesis use of persons with a transfemoral amputation or knee-disarticulation: A meta-synthesis of qualitative literature and focus group results.

OBJECTIVE: Persons with a transfemoral amputation or knee-disarticulation are heavily reliant on an adequate set of components for their prosthesis. To improve the process of adjusting the specific prosthetic properties to the expectations of the prosthesis users, it is of importance to first identify which factors have an influence on prosthesis use. Therefore, we aimed to identify factors that influence prosthesis use in adults with a transfemoral amputation or knee-disarticulation. METHODS: A qualitative meta-synthesis was conducted by searching five databases (last update January 20th 2022). Studies were considered eligible if they contained qualitative data about adult persons with a transfemoral amputation or knee-disarticulation with experience in using a prosthesis and focused on the users' opinions. All eligible studies were independently screened by two reviewers. The results sections of the included studies were entered in Atlas.ti software (v8) and coded using the framework approach. The quality of the included studies was assessed using the Critical Appraisal Skills Program (CASP) qualitative research checklist. Results of the meta-synthesis were validated with prosthesis users (n = 8) in a focus group. RESULTS: Out of 5757 articles, 14 studies were included. An overview of seven themes ('prosthesis related'; 'rehabilitation, costs and prosthetist'; 'mental'; 'physical'; 'social'; 'activities and participation' and 'walking') containing 84 factors was created. Ten factors were added during the focus group, resulting in an overview of 94 factors that may influence the prosthesis use of lower-limb prosthesis users. Participants would like more user-involvement from the rehabilitation team. The development of a patient decision aid could help this process in the future. CONCLUSION: The large number of factors demonstrates that there is a great variety between prosthesis users and the factors that influence their prosthesis use. Therefore, it is important to take individual preferences into account for the selection of a new prosthesis.

Functional recovery after reduced pediatric fractures of the forearm with respect to perceived limitations, common post-traumatic symptoms, range of motion, and dexterity: a prospective study.

PURPOSE: Studies on functional recovery after pediatric forearm fractures are scarce. Outcome measures are usually (retrospectively) incorporated to compare treatments. How these parameters recover has only rarely fallen within the scope. Aim was to provide insight into "normal recovery" by evaluating how limitations, post-traumatic symptoms, range of motion (ROM) and dexterity recuperate. MATERIALS AND METHODS: Prospective observational study regarding children 4 and 18 years with a reduced forearm fracture. Limitations, post-traumatic symptoms, ROM, and dexterity were evaluated 6 weeks, 3 and 6 months post-trauma. ROM of the unaffected side was used as a baseline. RESULTS: Of 54 participants 25.9% and 5.9% perceived limitations after 3 respectively 6 months. Pain, swelling and hypertrichosis were common symptoms. Movements distal from the elbow were restrained 6 weeks post-trauma. Supination and palmar flexion were most affected, followed by dorsal flexion and pronation. Palmar flexion and pronation were still affected after 3 months and associated with treatment invasiveness. Dexterity was diminished at 6 weeks only. CONCLUSIONS: Mild limitations are common. Further investigation of the association between pain, reduced sensitivity and hypertrichosis with treatment invasiveness is warranted. Regarding ROM supination, pronation, palmar and dorsal flexion should be incorporated in future studies. Dexterity is an unsuitable outcome measure.IMPLICATIONS FOR REHABILITATIONThis study relates to monitoring recovery from pediatric forearm fractures.Physicians ought to realize that one in four children experience limitations preceding 3 months post-trauma, in which case involvement of a hand therapist should be considered.Pain, swelling and especially hypertrichosis are common post-traumatic symptoms in children and should on itself not immediately raise concerns for complex regional pain syndrome (CRPS).To assess recovery of range of motion measuring pronation, supination, dorsal, and palmar flexion is sufficient.

Amputation and prosthetics of the lower extremity: The 2020 Dutch evidence-based multidisciplinary guideline.

BACKGROUND: Lower-limb amputations are rare but debilitating events in the lives of affected persons. Treatment of persons with amputation inherently involves many different health care professions at different stages leading to and after an amputation. There are prevailing clinical questions within the work field related to different facets of care including peri/postoperative aspects, prosthetic components, rehabilitation treatment, and health care processes. OBJECTIVES: To provide an up-to-date multidisciplinary evidence-based guideline for health care professionals involved in the treatment of persons with lower-limb amputation in the Netherlands. METHODS: Identification of key questions in a focus group, systematic review of the evidence (up to March 2019, using Embase and MEDLINE databases), and weighing considerations, culminating in clinical recommendations. RESULTS: Twelve key questions were formulated. Recommendations of two key questions were upheld in line with the previous 2012 guideline. Ten systematic literature searches were performed, leading to the inclusion of 59 studies. CONCLUSION: A summary of evidence-based conclusions, considerations, and recommendations of the 2020 guideline is presented.

The Working Alliance Inventory's Measurement Properties: A Systematic Review.

Measurement properties of the Working Alliance Inventory (WAI) and its various translations and adaptations for specific target groups have been investigated for over 30 years. No systematic review analyzing studies on measurement properties of the WAI has been conducted to date. COnsensus-based Standards for the selection of health Measurements INstruments (COSMIN) were developed for conducting high-quality systematic reviews on measurement properties in a transparent and standardized way. Aim of this study was to systematically review studies on measurement properties of the WAI, and its adapted versions, within psychotherapy, and other healthcare contexts using COSMIN criteria. PsycINFO, Medline, and EMBASE were searched (1989-2021). In all phases of the review procedure, study selection, data extraction, risk of bias assessment, rating of the quality of measurement properties, and rating of the quality of evidence for measurement properties, disagreement between reviewers was resolved by discussion. Results on validity, internal structure, reliability, construct validity, and responsiveness were analyzed. In total 66 studies were included. In most studies, evidence for measurement properties was according to COSMIN criteria, insufficient, lacking, or conflicting. Content validity was rated insufficient because neither patients nor healthcare professionals were involved in the development and validation process. Hence evidence for content validity of the WAI is unknown. Conflicting evidence was found for structural validity. Evidence for internal consistency could not be established. Limited evidence was found for inter-rater reliability and convergent validity. Conflicting evidence was also found for test-retest reliability and divergent validity. COSMIN criteria exposed persistent problems in validation studies of the WAI. These findings may indicate that measurement properties of the WAI are not up to current standards, or that COSMIN criteria may be less appropriate for assessing measurement properties of the WAI, or it could indicate both. The results of this systematic review suggest that WAI outcomes should be interpreted with caution and further research is needed regarding the content validity and hypotheses development. For the future, the theoretical framework underlying the measurement of the working alliance needs to be studied in psychotherapy and other health contexts, and tested in methodologically sound studies.

Interobserver and intraobserver reliabilities of determining the ventilatory thresholds in subjects with a lower limb amputation and able-bodied subjects during a peak exercise test on the combined arm-leg (Cruiser) ergometer.

The first (VT1) and second ventilator (VT2) (anaerobic) thresholds are used to individually prescribe exercise training programs. The purpose of this research was to analyze inter- and intraobserver reliabilities of determining VT1 and VT2 in subjects with lower limb amputation (LLA) and able-bodied (AB) subjects during a peak exercise test on the arm-leg (Cruiser) ergometer. Previously published data of exercise tests on the Cruiser ergometer of subjects with LLA ( n = 17) and AB subjects ( n = 30) were analyzed twice by two observers. The VT1 and VT2 were determined based on ventilation plots. Differences in determining the VT1 and VT2 between the observers for the first and second analyses were analyzed. To quantify variation in measurement a variance component analysis was performed. Bland-Altmann plots were made, and limits of agreement were calculated. The number of observations in which thresholds could not be determined differed significantly between observers and analysis. Variation in VT1 between and within observers was small (0-1.6%) compared with the total variation, for both the subjects with an LLA and AB subjects. The reliability coefficient for VT1 was more than 0.75, and the limits of agreement were good. In conclusion, based on the results of this study on a population level, VT1 can be used to prescribe exercise training programs after an LLA. In the current study, the determination of VT2 was less reliable than VT1. More research is needed into the clinical application of VT1 and VT2 during a peak exercise test on the Cruiser ergometer.

More than half of persons with lower limb amputation suffer from chronic back pain or residual limb pain: a systematic review with meta-analysis.

PURPOSE: The aim of this study is to systematically review and critically assess the methodological quality of literature regarding prevalence, characteristics and factors influencing pain, other than phantom limb pain (PLP) in persons with lower limb amputation (LLA). MATERIALS AND METHODS: A systematic review was performed (PROSPERO CRD42019138018). Literature was searched using PubMed, EMBASE, PsycINFO, and PEDro. Studies were included if describing pain other than PLP at least three months after amputation. For residual limb pain (RLP) and back pain, a meta-regression was performed. RESULTS: Fifty-one studies were included in which predominantly young males with a unilateral traumatic amputation using a prosthesis were investigated. Pooled prevalence of RLP was 0.51 (95% CI 0.40-0.62) with a positive association with presence of back pain (p = 0.044) in the univariate meta-regression. Pooled prevalence of back pain was 0.55 (95% CI 0.45-0.64), with a positive association of time since amputation (p < 0.001) and co-occurrence of RLP (p = 0.050). CONCLUSIONS: Back pain and RLP are common after LLA. The prevalence of back pain was positively associated with the presence of RLP, and vice versa. Future studies should give more attention to other chronic pain types, to persons with a diabetic or vascular cause of amputation, and to pain-related interference.Implications for RehabilitationBoth back pain and residual limb pain occur in more than 50% of persons with lower limb amputation (LLA), and both pain types are positively associated.Clinicians should be aware that chronic pain is common after LLA and can have a significant impact on the functioning of persons with LLA.Future research on this topic should give more attention to other chronic pain types, to persons with a diabetic or vascular cause of amputation, and to pain-related interference.

Fitting transtibial and transfemoral prostheses in persons with a severe flexion contracture: problems and solutions - a systematic review.

PURPOSE: In persons with a hip or knee flexion contracture ≥25°, fitting a prosthesis is said to be difficult. This systematic review aims to assess the evidence for fitting of a prosthesis in persons with a severe contracture (≥25°) after a lower limb amputation. METHOD: PubMed, Embase, Scopus, CINAHL, and Orthotics & Prosthetics Virtual Library databases were searched from inception to December 2019, using database specific search terms related to amputation, prosthesis, and contracture. Reference lists of included studies were checked for relevant studies. Quality of the included studies was assessed using the critical appraisal checklist for case reports (Joanna Briggs Institute). RESULTS: In total, 13 case studies provided evidence for fitting of a prosthesis in more than 63 persons with a transtibial amputation and three with a transfemoral amputation, all of whom had a hip or knee flexion contracture ≥25°. Some studies found a reduction in contractures after prosthesis use. CONCLUSIONS: Several techniques for fitting a prosthesis in case of a flexion contracture ≥25° were found. Contracture reduction occurred in some cases and was possibly related to prosthesis use. Fitting a transtibial or transfemoral prosthesis in persons with a lower limb amputation with a severe flexion contracture is possible.IMPLICATIONS FOR REHABILITATIONThis study provides information on prosthesis prescriptions and adaptations for persons with a transfemoral and transtibial amputation with a flexion contracture ≥25°.The fitting of bent prostheses is not limited by prosthetic components and techniques.Parallel to the use of bent prostheses, it is also important to treat the contracture.

Participants' unspoken thoughts and feelings negatively influence the therapeutic alliance; a qualitative study in a multidisciplinary pain rehabilitation setting.

PURPOSE: This study aimed to explore factors that influence participants' perceptions of the therapeutic alliance with healthcare professionals; their participation in the alliance; and their commitment to treatment in a multidisciplinary pain rehabilitation setting. MATERIALS AND METHODS: A qualitative research-design was used and 26 participants in a multidisciplinary pain rehabilitation program were interviewed in-depth. RESULTS: Initially, participants reported to be satisfied with their healthcare professionals. After deeper reflection on the therapeutic alliance, several unspoken thoughts and feelings and relational ruptures emerged. Almost all participants mentioned a history of disappointing and fragmented healthcare, and they reported on how this affected their cognitions, perceptions, and beliefs about the current program. Participants felt insufficiently empowered to voice their concerns and regularly chose to avoid confrontation by not discussing their feelings. They felt a lack of ownership of their problems and did not experience the program as person-centered. CONCLUSIONS: Several factors were found that negatively influence the quality of therapeutic alliance (agreement on bond) and efficacy of the treatment plan (agreement on goals and tasks). To improve outcomes of pain rehabilitation, healthcare professionals should systematically take into account the perceptions and needs of participants, and focus more on personalized collaboration throughout the program offered.Implications for rehabilitationDifferences in perceptions and experiences of pain, together with differences in beliefs about the causes of pain, negatively influence the therapeutic alliance.When participants and healthcare professionals operate from different paradigms, it is important that they negotiate these differences.From the perspective of participants, a clear-cut organization of healthcare that encourages collaboration is required.It is important to focus on personalized collaboration from the start and during treatment, and to recognize and discuss disagreement on diagnosis and treatment plans.During this collaboration, healthcare professionals should systematically take into account the perceptions and needs of the participants.

Learning self-care skills after spinal cord injury: a qualitative study.

BACKGROUND: People with a recent spinal cord injury (SCI) often follow intensive rehabilitation. Learning appropriate self-care, deal with their impairments and prevent secondary health conditions (SHCs), is highly important during rehabilitation. To date it is not clear how self-care skills are taught to people with SCI. The objective of this study was to understand how people with SCI experienced the learning of appropriate self-care skills during inpatient rehabilitation, including the role of the rehabilitation team. METHODS: Individual semi-structured interviews were conducted with 15 people with SCI, recently discharged from initial inpatient rehabilitation. Interviews were audio-taped, transcribed and analyzed thematically. RESULTS: Two main themes and seven sub-themes were identified. Participants stated that the contribution of the rehabilitation team to learning self-care, including prevention of SHCs, was mostly made by optimizing opportunities to learn through experience. For preventing SHCs, education and lessons learned from the professionals during therapy and the formal educational program, was experienced as especially important. Further, the motivational attitude of the professionals which participants found stimulating and was based on respect, combined with their positive contribution as one team, were seen as essentials elements for learning appropriate self-care. However participants did not recognize the contribution of the nursing staff as part of their rehabilitation, although it was seen as very important. An important aspect of the participants' own contribution was challenging oneself to learn self-care. This was done in different ways by the participants. Further, their own mental adjustment was considered important in the learning process. The gaining of confidence was by most participants seen as personal characteristic, although they also recognized the importance of the team effort and the experiences they underwent. CONCLUSIONS: Learning appropriate self-care was mostly done through experience, by challenging themselves, and making use of the opportunities given by the members of the rehabilitation team. The same strategies used by the rehabilitation team to teach people with SCI to perform appropriate self-care, were also helpful for the participants to gain confidence. Explicit attention for self-care training as an important goal in SCI rehabilitation may strengthen the nursing staff's role and stimulate interdisciplinary working.

The association between body mass index and skin problems in persons with a lower limb amputation: an observational study.

BACKGROUND: Obesity is common in persons with a lower limb amputation, an amputation can also lead to further weight gain. Data regarding the prevalence of obesity in the Dutch population with a lower limb amputation are lacking. Furthermore, the impact of obesity on skin problems of the residual limb and the need of prosthetic repairs is unknown. The aim of this study was to determine the prevalence of obesity in Dutch persons with a lower limb amputation and to investigate the relationship between body weight, body mass index and skin problems of the residual limb and the frequency of prosthetic repairs. METHODS: A survey was performed among adults with a unilateral lower limb amputation due to any cause, and who are user of a prosthesis. The survey consisted of measurement of the subjects' body height and weight, a questionnaire which assessed self-reported skin problems in the previous month and factors potentially associated with these skin problems, and assessment of the frequency of visits to the orthopedic workshop. RESULTS: In total, 413 persons were enrolled. Of them, 39% (95 % confidence interval 35;44) were overweight and 28% (95% confidence interval 24;33) were obese. A total of 77% (95% confidence interval 73;81) reported one or more skin problems in the past month. Body weight and body mass index were neither associated with the presence of skin problems in general nor with the number of prosthetic repairs. Persons with severe skin problems had a slightly lower body mass index (26.6 kg/m2 vs. 28.0 kg/m2, p = 0.012). Persons with skin problems were younger than those without (difference in means 6.0 years (95% confidence interval 3.0;8.9)). CONCLUSIONS: Our findings show that obesity is common in the Dutch ambulant population with a lower limb amputation, with a prevalence being higher than in the general Dutch adult population. However, its negative impact on the presence of skin problems and the frequency of prosthetic repairs may be limited.

Cycling in people with a lower limb amputation.

BACKGROUND: To evaluate cycling participation and identify barriers and facilitators related to cycling participation in people with a lower limb amputation (LLA) in the Netherlands. METHODS: A questionnaire was sent to adults with a LLA between March and August 2019 to obtain information regarding prosthesis, individual's characteristics, amputation, cycling barriers and facilitators, and prosthetic satisfaction. The questionnaires were distributed via 8 orthopedic workshops, post and were given directly. To find cycling predictors, variables associated with cycling (p < 0.1) were entered into a logistic regression analysis. Non-significant variables were removed manually. RESULTS: Participants (n = 207, 71% males) had a mean age of 62.0 ± 13.0 years. The most frequent level of amputation was transtibial (42%), and trauma was the most frequent cause of amputation (43%). After the LLA, 141 participants (68%) cycled for recreation (80%), physical fitness (74%), and transport (50%). In the past six months, cyclists cycled for recreation (79%) and transport (66%). Most cycled less than once a day. Recreational cyclists cycled alone (75%) for a median duration of 45 min or 14 km per ride. Cyclists with a transportation purpose usually cycled to go shopping (80%) or to visit friends (68%), with a median duration of 20 min or five kilometers per ride. Cyclists reported more facilitators (median (IQR) = 5 (3, 7) than non-cyclists 0 (0, 3). The majority of cyclists reported a positive attitude toward cycling (89%) and cycled because of health benefits (81%). A dynamic foot (odds ratio: 5.2, 95% CI 2.0, 13.3) and a higher number of facilitators (odds ratio: 1.3, 95% CI 1.2, 1.5) positively predicted cycling, whereas the presence of other underlying diseases (odds ratio: 0.4, 95% CI 0.2, 0.9) negatively predicted cycling (R2: 40.2%). CONCLUSION: In the Netherlands, the majority of adults cycled after a LLA, mainly for recreational purposes. A dynamic foot, a higher number of facilitators, and no other underlying diseases increases the likelihood of cycling after a LLA. The results suggest that personal motivation and a higher mobility level could be the key to increasing cycling participation. Future research should determine the association between motivation, mobility levels, and cycling with a LLA.

Psychological factors during rehabilitation of patients with Achilles or patellar tendinopathy: a cross-sectional study.

OBJECTIVE: to examine psychological factors during rehabilitation of patients with Achilles or patellar tendinopathy as well as the association between psychological factors and tendinopathy severity, sport participation, and satisfaction with activity level and tendon function. DESIGN: cross-sectional study. SETTING: online survey platform. PARTICIPANTS: 119 patients (mean age: 44 years (SD 14)) diagnosed with Achilles or patellar tendinopathy. MAIN OUTCOME MEASURES: A range of patient-reported psychological and outcome measures were recorded. Multivariate regression analyses were performed to establish the association between each psychological factor and outcome measures, adjusted for relevant confounders. RESULTS: Psychological readiness and confidence to return to sports (I-PRRS) and pain catastrophizing (PCS) were significantly associated with tendinopathy severity (modified VISA), sport participation(OSTRC-O), and satisfaction. Kinesiophobia (TSK) and the importance to patients of returning to pre-injury activity level were significantly associated with sports participation and satisfaction. CONCLUSION: The current study provides evidence of impairments in psychological factors during rehabilitation of patients with Achilles and patellar tendinopathy. Most investigated psychological factors were associated with tendinopathy severity, function, participation, and satisfaction. Physical therapists should recognize patients with lack of psychological readiness to return to sports and also patients with kinesiophobia or catastrophizing thoughts when experiencing pain.

Pre-operative rehabilitation in lower-limb amputation patients and its effect on post-operative outcomes.

Major lower-limb amputation (LLA) is a life-changing event associated with poor post-operative physical and psychological functioning and decreased quality of life. The general physical condition of most LLA patients prior to surgery is already significantly deteriorated due to chronic peripheral vascular disease often in combination with diabetes. Pre-operative rehabilitation (also called 'pre-rehabilitation') is an increasingly common strategy used in multiple patient populations to improve patients' physical and mental condition prior to surgery, thus aiming at improving the post-operative patient outcomes. Given the positive effects of post-surgical outcomes in many patient populations, we hypothesize that pre-operative rehabilitation will improve post-operative outcomes after LLA. To test this hypothesis, a literature search of PubMed, EMBASE, EBSCOhost, Web of Science and ScienceDirect was performed to identify studies that investigated the impact of a pre-operative rehabilitation therapy on post-operative outcomes such as length of hospital stay, mobility, physical functioning, and health related quality of life. No time restrictions were applied to the search. Only articles published in English were included in the selection. Two studies satisfied the eligibility criteria for inclusion in the review, one qualitative and one quantitative study. The quantitative study reported a beneficial effect of pre-rehabilitation, resulting in post-operative mobility (at least indoor ambulation) in 63% of the included LLA patients. There is a need for prospective clinical studies examining the effect of pre-rehabilitation on post-operative outcomes to be able to confirm or reject our hypothesis. Although the hypothesis seems plausible, evidence is lacking to support our hypothesis that pre-operative rehabilitation will improve post-operative outcomes in patients with LLA. The qualitative study indicated that integrating pre-rehabilitation in the care for LLA patients seems to be limited to a selected group of dysvascular patients, but at this stage cannot be advised based on current evidence even in this subgroup. Further research is needed to clarify whether such an intervention prior to amputation would be a useful and effective tool for optimizing post-operative outcomes in LLA patients.

Enhancing our conceptual understanding of state and trait self-efficacy by correlational analysis of four self-efficacy scales in people with spinal cord injury.

BACKGROUND: Self-efficacy is an important determinant of adjustment following spinal cord injury. Self-efficacy is defined as the belief that one can successfully execute behavior required to produce the desired outcomes. In its original conceptualization, self-efficacy refers to the confidence that people have in their ability to accomplish specific tasks and behaviors within a specific context. Over the years these situation specific aspects have been unconfined and multiple constructs of self-efficacy have been proposed. The most common is a division in trait and state self-efficacy. Another used division that is utilized is between general, domain-specific and task-specific self-efficacy. The scientific support for these constructs is to date still unclear. The objective of this study was to enhance the understanding of the self-efficacy construct by comparing four self-efficacy scales designed to measure three aspects of self-efficacy (general versus domain-specific versus task-specific) in people with spinal cord injury. METHODS: Dutch and Australian adults with spinal cord injury (N = 140) completed four frequently used self-efficacy scales; the Moorong Self-efficacy Scale, General Self-efficacy Scale, University of Washington Self-efficacy Scale and a Self-care Self-efficacy Scale approximately 6 months after their inpatient rehabilitation. Pearson correlations examined inter-relationships between the scales. RESULTS: Hypothesized strong correlations between scales measuring similar aspects of self-efficacy were found (correlations 0.50-0.65). However, the hypothesized weak to moderate correlations between scales measuring diverging aspects of self-efficacy were only partly found (correlations 0.31-0.74), with 7 out of 12 correlations being strong instead of moderate. CONCLUSIONS: The expected distinctions between the three aspects of self-efficacy was not demonstrated. All four scales measure a common latent construct, most likely general self-efficacy aspects. Further research is necessary to find ways to improve the measurement of domain-specific and task-specific aspects of SE, so that they are sensitive enough to capture change over time, and thus enhance clinical outcomes of people with SCI as they adjust to their disability.
