RESUMO
OBJECTIVE: To explore the relationship between sociodemographic, clinical, and neurophysiological variables and health-related quality of life (HR-QOL) of patients with phantom limb pain. METHODS: This is a cross-sectional analysis of a previous clinical trial. Univariate and multivariate linear and logistic regression analyses were used to model the predictors of HR-QOL. We utilized a sequential modeling approach with increasing adjustment levels, controlling for age and sex, and other relevant clinical variables (time since amputation, level of amputation, and pain). HR-QOL was assessed by the SF-36 Health Survey and its eight subdomains. RESULTS: We analyzed baseline data from 92 patients with lower-limb amputations. They were mostly male (63%), 45.2 ± 15.6 years, with a mean time since amputation of 82.7 ± 122.4 months, and an overall SF-36 score of 55.9 ± 21.5. We found an association between intracortical facilitation in the affected hemisphere (ICF), gabapentin usage, and HR-QOL. ICF is a predictor of better HRQOL, whereas gabapentin usage was associated with a poorer HR-QOL, with the main model explaining 13.4% of the variance in the outcome. For the SF-36 subdomains, ICF was also a positive predictor for social functioning, bodily pain, and vitality, while medication usage was associated with lower scores in mental health, general health perception, bodily pain, and vitality. CONCLUSION: We found firsthand two new independent predictors of HR-QOL in individuals with PLP, namely, the neurophysiological metric ICF and gabapentin usage. These results highlight the role of the motor cortex excitability in the HR-QOL and stress the need for treatments that favor the neuroplastic adaptation after amputation, for which ICF may be used as a possible marker.
RESUMO
BACKGROUND: Critical limb ischemia represents an advanced stage of peripheral arterial disease. Angioplasty improves blood flow to the limb; however, some patients progress irreversibly to lower limb amputation. Few studies have explored the predictive potential of biomarkers during postangioplasty outcomes. AIM: To evaluate the behavior of endothelial progenitor cells in patients with critical limb ischemia, in relation to their postangioplasty outcome. METHODS: Twenty patients with critical limb ischemia, candidates for angioplasty, were enrolled. Flow-mediated dilation, as well as endothelial progenitor cells (subpopulations CD45+/CD34+/CD133+/CD184+ and CD45+/CD/34+/KDR[VEGFR-2]+ estimated by flow cytometry) from blood flow close to vascular damage, were evaluated before and after angioplasty. Association with lower limb amputation during a 30-day follow-up was analyzed. RESULTS: Endothelial progenitor cells were related with flow-mediated dilation. A higher number of baseline EPCs CD45+CD34+KDR+, as well as an impaired reactivity of endothelial progenitor cells CD45+CD34+CD133+CD184+ after angioplasty, were observed in cases further undergoing major limb amputation, with a significant discrimination ability and risk (0.75, specificity 0.83 and RR 4.5 p < 0.05). CONCLUSIONS: Endothelial progenitor cells were related with endothelial dysfunction, whereas a higher baseline number of the subpopulation CD45+CD34+KDR+, as well as an impaired reactivity of subpopulation CD45+CD34+CD133+CD184+ after angioplasty, showed a predictive ability for major limb amputation in patients with critical limb ischemia.

Background and Aim: Knowledge translation processes are necessary for improving patients' and communities' health outcomes. The aim of this study was to systematically develop evidence-based recommendations for people over 16 years of age who are in risk for or have suffered a lower limb amputation for medical reasons (vascular, diabetes mellitus) or trauma (civilian or military trauma) in order to improve function, quality of life, decrease complications and morbidity. Methods: Following the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach we developed a Clinical Practice Guideline (CPG) for lower limb amputees with funding from the Ministry of Health in Colombia and participation of a multidisciplinary group. We included patients' preferences. Based on the scope, purposes and objectives the questions were elaborated with the PECOT strategy. The evidence search was performed for each question in the main databases: Cochrane Library, Embase and PubMed, without time limit or language restriction. Teams were formed with thematic experts and clinical epidemiologists to review the clinical studies, describe the evidence, and evaluate the quality of the body of evidence with the GRADE methodology. The recommendations were made according to the judgments proposed by the GRADE working group. We conducted a stakeholder's dialogue as a mechanism for the external validation of the guideline implementation. Results: The CPG included 43 recommendations related to the diagnosis, surgical treatment, rehabilitation, prescription and adaptation of the prosthesis. They were strong in favor 37.2, weak in favor 53.5, strong against 2.3, Weak against 7.0%. Quality of evidence was high in 0, moderate in 11.6, low in 58.1, and very low 30.2%. Discussion: In 93% of the recommendations, the quality of the evidence was between low and very low. This is why it was so important to validate and discuss each recommendation with an expanded multidisciplinary group. The research group identified 25 interventions and five milestones to be prioritized in the implementation and in the stakeholder's dialogue participants identified opportunities and barriers for implementation of recommendations. Conclusion: It is necessary to develop a national policy for implementation strategies of CPG recommendations that promotes the necessary arrangements for the provision of services for diagnosis, treatment, and rehabilitation of individuals with amputations.

RESUMO
OBJECTIVE: The purpose of this investigation was to assess participants' self-reported satisfaction with an adjustable, immediate fit transtibial prosthetic system as compared to their conventionally fabricated prosthetic device. DESIGN: A prospective study involving a two-week single-group pre-post intervention design. SETTING: Physical medicine and rehabilitation clinic of a university hospital. PARTICIPANTS: Adults (N=27) with transtibial limb loss. INTERVENTION: Participants were fit with the iFIT prosthetic system and instructed to wear it for a two-week evaluation period. MAIN OUTCOME MEASURE: A modified PEQ scale was completed on the participant's conventional prosthetic during the initial visit and the iFIT system after the two weeks. RESULTS: Twenty-seven persons with lower limb loss were enrolled. Three were lost to follow up leaving twenty-four subjects with completed data. Three subjects had recent amputations with no conventional device for comparison. The Modified PEQ scores were significantly higher for the iFIT prosthetic in comparison to their conventional device (29.18 [SD= 4.63] vs 23.82 [SD=6.38], p <0.01). Subjects were also found to perceive significantly better temperature control with the iFIT prosthetic system (4.19 [SD= 0.68] vs 2.97 [SD=1.02], p <0.001). Subjects did not report any skin breakdown, prosthetic issues, or falls. CONCLUSION: This immediate fit, adjustable transtibial prosthesis demonstrated significantly better patient satisfaction and temperature perception compared to conventional devices. These results are consistent with previous findings and further support the efficacy of an immediate fit adjustable transtibial prosthetic system. Longer term studies in the United States and internationally are underway to assess the durability and efficacy of this new prosthesis in different populations and settings.
RESUMO
BACKGROUND: The precise epidemiological evaluation of amputations is difficult. It is a serious public health and economic problem with a high death rate. The proportion of amputees with pre-amputation vascular status remains unknown. The main objective of our study was to evaluate the proportion of patients with lower limb amputation who had a pre-procedural vascular assessment. The secondary objectives were to evaluate the risk of amputation at the admission of these patients, estimate the incidence of amputations in Martinique, and to collect epidemiological data on this category of patients. MATERIAL AND METHODS: We conducted an epidemiological, retrospective, and observational study, over the year 2018 between January 01 and December 31, including all adults' patients who underwent an amputation of the lower limb at the university hospital center of Martinique. RESULTS: Among the 170 included patients, 79 (46%) patients had a major lower limb amputation. The incidence of amputations in 2018 was estimated at 48.9/100,000 inhabitants. The vascular assessment was performed for 110 (65%) patients. For the other 60 (35%) patients who did not have a vascular assessment, 53 (88%) had a severe infection. This assessment was significantly related to the amputation level: a vascular assessment was performed in 97 (70%) patients with below the knee amputation versus 13 (41%) patients with above the knee amputation (P<0.01). The WIfI classification system found a high risk of amputation for 152 (89%) of patients but also a benefit of revascularization ranked high for 138 (81%) of them. The origin of amputation was limb ischemia for 125 (68%) patients. CONCLUSION: A significant number of patients who underwent lower limb amputation did not have a pre-procedural vascular assessment. Many improvements in the health care are therefore to be implemented. The upcoming M@diCICAT project in Martinique will contribute in the improvement of patient management. The incidence of amputation in Martinique is considered high compared to other countries (French national incidence in 2003=24.8/100,000 inhabitants), and it seems to have remained stable since 2008. Our population is considered to be at high risk of amputation by the SVS-WIfI classification. This score seems adapted to anticipate the evolution of these patients and could be useful in daily practice.

The calculation of symmetry in amputee gait is a valuable tool to assess the functional aspects of lower limb prostheses and how it impacts the overall gait mechanics. This paper analyzes the vertical trajectory of the body center of mass (CoM) of a group formed by transfemoral amputees and non-amputees to quantitatively compare the symmetry level of this parameter for both cases. A decomposition of the vertical CoM into discrete Fourier series (DFS) components is performed for each subject's CoM trajectory to identify the main components of each pattern. A DFS-based index is then calculated to quantify the CoM symmetry level. The obtained results show that the CoM displays different patterns along a gait cycle for each amputee, which differ from the sine-wave shape obtained in the non-amputee case. The CoM magnitude spectrum also reveals more coefficients for the amputee waveforms. The different CoM trajectories found in the studied subjects can be thought as the manifestation of developed compensatory mechanisms, which lead to gait asymmetries. The presence of odd components in the magnitude spectrum is related to the asymmetric behavior of the CoM trajectory, given the fact that this signal is an even function for a non-amputee gait. The DFS-based index reflects this fact due to the high value obtained for the non-amputee reference, in comparison to the low values for each amputee.

BACKGROUND: During the rehabilitation phase, physical exercise is a key element that requires an assessment of the best alternatives for application since the pre-prosthetic phase (PPF) for an accurate prescription. Therefore, the assessment of fitness for health (FFH) shall be included in the initial rehabilitation process. OBJECTIVE: To develop a FFH evaluation battery (Evam1) for pre-prosthetic unilateral lower-limb amputees (PPULLA). METHOD: A descriptive study of the theoretical construction and validation of a FFH evaluation battery based on a review of international literature for tests that measure amputee physical capability. RESULTS: During the scientific literature review, no batteries designed with this goal were found. We therefore designed a battery that was assembled of five tests for anthropometry, aerobic capacity, strength and flexibility. Combined leg and arm cycloergometrics, isokinetic dynamometry, and flexi test are the most reliable tests for the corresponding assessment of each component. CONCLUSIONS: PPF is of great importance, since the basic physical capabilities are altered due to long immobilization and hospitalization periods, inadequate postures, alteration of basic daily activities, and decrease in participation in sports, recreational, and work activities. This is a fundamental proposal, given that the procedures for FFH assessment of PPULLA have been rarely addressed, thus limiting the information on assessment methods, processes and/or tests established for these procedures.

We characterized physical activity (PA) and its relation to physical function and number of comorbidities in people with diabetes and transtibial amputation (AMP), people with diabetes without AMP, and nondisabled adults without diabetes or AMP. Twenty-two individuals with type 2 diabetes mellitus (DM) and transtibial amputation (DM+AMP), 11 people with DM, and 13 nondisabled participants were recruited for this cross-sectional cohort study. Measures included PA volume and intensity, a Timed Up and Go test, a 2-min walk test, and number of comorbidities. The nondisabled group performed greater amounts of PA than the DM group, who performed greater amounts of PA than the DM+AMP group. PA was related to physical function in the DM group and in the DM+AMP group, whereas no such relationship existed in the nondisabled group. PA was not related to number of comorbidities in any group. These findings suggest the ability to walk may affect overall performance of PA. Alternately, PA may alleviate walking problems. This possibility is of interest because issues with walking may be modifiable by improved levels and intensity of PA. PA's lack of relation to number of comorbidities suggests that factors beyond multiple morbidities account for group differences in PA.

Little evidence exists to support the presence of differences in spatiotemporal gait parameters and ambulation ability between those individuals with traumatic and nontraumatic lower-limb amputation (LLA). We conducted an exploratory study of 81 male Veterans with unilateral amputation to quantify differences in spatiotemporal gait parameters and ambulatory mobility between Veterans with traumatic and nontraumatic LLA. Furthermore, we identified variables that significantly contributed to the explanation of variability in modified 2-min walk test distance. All participants completed the modified 2-min walk test and a spatiotemporal gait analysis using an instrumented walkway during a routine physical therapy visit. Veterans with nontraumatic LLA walked significantly shorter mean distances during a modified 2-min walk test than Veterans with traumatic LLA. Variables identified as significant contributors to modified 2-min walk test variability were amputated limb stance time, amputated limb step length, and percentage of the gait cycle spent in double support. These findings demonstrate that differences in spatiotemporal gait parameters and ambulatory mobility exist between Veterans with traumatic and nontraumatic LLA and identify important spatiotemporal parameters of gait contributing to this decline. These parameters should be considered as targets for intervention and future investigation.
