“…The Italian study only provided the duration of education in years, with a range from 5 to 14 years of formal education. In our study, patients with basic education levels would be at risk of worse adaptation to fitting, and consequently, of lower levels of quality of life and satisfaction [6,15].…”

“…The employment status of the subjects was another factor included in all the studies, except the one carried out in the Netherlands [6,9,11,15]. In all cases, most of the subjects were unemployed, which is not surprising considering the respondents' ages and their disability.…”

“…The most frequent indication of amputation is lower limb ischemia after having tried several revascularizations; the most frequent comorbidities are: diabetes mellitus (DM) (80.6%), coronary ischemic pathology (66.2%) and hypertension arterial (HTA) (68.2%) [5]. As Rubio et al and Miller et al [5,6] concluded, the diabetic population has a risk of suffering from a lower limb amputation between 10 and 30 times higher than the population that does not suffer from it.…”

Background: To identify the sociodemographic variables independently related to the different dimensions of the Prosthesis Evaluation Questionnaire (PEQ). Methods: An observational, cross-sectional study was conducted, with a sample of 61 Spanish vascular amputees (Valencia, Spain). Included in this study are the results of the PEQ and explanatory-sociodemographic variables, as well as a descriptive and analytic analysis. Results: Gender differences were observed in “appearance” and “perception of appearance” (significantly higher levels for men). Older patients tended to have worse scores in “utility”, “frustration”, “social burden” and “deambulation”. More favorable scores were obtained for those residing in rural areas in “social burden” and “deambulation”. Educational level had a positive correlation with scores. Conclusion: Gender, age, place of residence, and educational level could be considered determinants of the quality of health related to prosthesis adaptation in vascular amputees. Clinical relevance: Knowing the influential variables in the process of prosthetization will allow better adaptation and an improvement in the quality of life.

“…The quantitative findings reported here provide foundation knowledge (ie, identify psychosocial factors related to disability) to support the development and testing of rehabilitation interventions for people within this specific group. Data collection and analysis procedures for this study were informed by prior qualitative and quantitative research focused on the influence of psychosocial factors on rehabilitation outcomes after LLA 19‐22 …”

“…Common psychosocial targets include self‐efficacy, social support, and motivation. Specifically for people with LLA, self‐efficacy is associated with physical activity and disability, and social support by family, friends, and peers is consistently recommended to facilitate adaptation after LLA 2,19,20 . Motivation has also been implicated as a potential psychosocial target to improve physical activity after dysvascular LLA 21 .…”

Background Interventions targeting psychosocial factors may improve rehabilitation outcomes for prosthesis users after lower‐limb amputation (LLA), but there is a need to identify targeted factors for minimizing disability. Objective To identify psychosocial factors related to disability for prosthesis users after LLA in middle age or later. Design Cross‐sectional study. Setting General community. Participants Participants with LLA (N = 122) were included in this cross‐sectional study if their most recent LLA was at least 1 year prior, they were ambulating independently with a prosthesis, and they were between 45 and 88 years old. Interventions Not applicable. Main Outcome Measures Disability, the primary outcome, was measured using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS). Candidate psychosocial variables included self‐efficacy, social support, and motivation, measured using the Self‐Efficacy of Managing Chronic Disease questionnaire (SEMCD), Multidimensional Scale of Perceived Social Support questionnaire (MSPSS), and modified contemplation ladder (mCL), respectively. The hypothesis was that greater self‐efficacy, social support, and motivation would be associated with lower disability when controlling for covariates. Results The covariate model, including etiology, age, sex, U.S. military veteran status, LLA characteristics, time since LLA, medical complexity, and perceived functional capacity, explained 66.1% of disability variability (WHODAS 2.0). Backward elimination of candidate psychosocial variables stopped after removal of motivation (P = .10), with self‐efficacy (P < .001) and social support (P = .002) variables remaining in the final model. The final model fit was statistically improved (P < .001) and explained an additional 6.1% of disability variability when compared to the covariate model. Conclusions Greater self‐efficacy and social support are related to lower disability after LLA. Findings suggest there may be a role for interventions targeting increased physical function, self‐efficacy, and social support for ambulatory prosthesis users after LLA in middle age or later, especially when complicated by multiple chronic conditions.

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.
