Limb Prosthesis

The precise positioning design of upper limb prostheses is important for patients with upper limb disability. In this study, we propose an upper limb prosthesis with a negative pressure design. Mechanical analysis is performed to obtain the force and moment equilibrium equations. Then, the individual discipline feasible method is performed to decouple the original problem into a three-sub-discipline problem. A minimum of three shoulder straps of tension is obtained during optimization using the Isight harness scheme. The prosthetic socket can be firmly attached to the human body. Further experiments verify that the proposed device meets the basic requirements of wearing.

Background. There is a lack of studies on adjustment to upper limb prosthesis with large representative samples that would compare different prosthesis types and use standardised outcome measures. Hence, we wanted to assess satisfaction with, and level of adjustment to, an upper-limb prosthesis among people after an upper limb amputation in our country. Material and methods. We conducted a cross-sectional descriptive study. The TAPES-R questionnaire was mailed to 431 patients identified from electronic health records at national specialist outpatient clinics for rehabilitation of people after upper limb amputation. Results. 191 patients (44%) responded and were subsequently ascertained to be a representative sample of the population of upper limb amputees in our country. Univariate analyses and multiple regression models indicated that, on average, overall satisfaction is lower among those who have received their current prosthesis more recently, women might be more satisfied with prosthesis than men, above-elbow amputees experience more activity restrictions than those with amputation at a lower level, patients with amputated fingers or palm are more satisfied with the prosthesis than others, and so are those who had amputation following an accident as compared to other reasons. Conclusion. We reliably identified some systematic factors, but it is individual factors and experience that largely determine adjustment to and satisfaction with a prosthesis following an upper limb amputation.

The purpose of the elbow lock incorporated in an artificial arm is discussed and the difficulties encountered in the operation of purely mechanical devices are outlined. An electrically driven locking mechanism has been built which is controlled by the electromyogram (e.m.g.) of the surviving muscles in the upper arm. Hybrid technology is ideally suited to the construction of the associated electronic circuitry and to many similar applications now being considered in attempts to improve the performance of upper-limb prostheses.

ABSTRACT Objective: To establish reference values for the Unsupported Upper Limb EXercise (UULEX) test, which measures peak arm exercise capacity, in healthy adults in Brazil. Methods: This was a cross-sectional study, involving presumably healthy individuals ≥ 30 years of age who completed questionnaires and underwent spirometry. All of the individuals underwent two UULEX tests 30-min apart. The outcome measure was the maximum time (in min) to completion of the test. Results: We included 100 individuals between 30 and 80 years of age. The mean test completion time was 11.99 ± 1.90 min among the women and 12.89 ± 2.15 min among the men (p = 0.03). The test completion time showed statistically significant correlations with age (r = −0.48; p < 0.001), gender (r = 0.28; p = 0.004), body mass index (BMI, r = −0.20; p = 0.05), and height (r = 0.28; p = 0.005). Linear regression analysis showed that the predictors of UULEX completion time were age (p = 0.000), BMI (p = 0.003), and gender (p = 0.019), which collectively explained 30% of the total variability. The mean UULEX completion time was 6% lower for the women than for the men. Conclusions: The present study was able to establish reference values for the UULEX test in healthy adults in Brazil. The values were influenced by age, gender, and BMI.

Objective: To estimate the prevalence of SARS-CoV-2 antibodies in an asymptomatic population in the state of Sergipe, Brazil. Methods: This cross-sectional study with stratified sampling (sex and age) includeD serological immunofluorescent tests for IgM and IgG on samples from 3 046 asymptomatic individuals. Sample collection was performed in wet-markets of the 10 most populous cities of Sergipe, Brazil. Exclusion criteria included symptomatic individuals and health workers. The presence of comorbidities was registered. Results: Of the 3 046 participants, 1 577 (51.8%) were female and 1 469 (48.2%) were male; the mean age was 39.76 (SD 16.83) years old. 2 921 tests were considered valid for IgM and 2 635 for IgG. Of the valid samples, 347 (11.9% [CI 10.7%–13.1%]) tested positive for IgM and 218 (8.3% CI 7.2%–9.4%]) tested positive for IgG. Women over 40 had the highest prevalence for IgM (group C, p=0.006; group D p=0.04). The capital Aracaju displayed the highest prevalence for both antibodies; 83 (26.3% [CI 21.6%-31.6%]) tested positive for IgM and 35 (14.6% [CI 10.4%-19.7%]) for IgG. The most prevalent comorbidities were hypertension (64/123 individuals) and diabetes (29/123). Conclusions: A high prevalence of SARS-CoV-2 antibodies was found among asymptomatic persons in Sergipe. Women over 40 showed the highest rates. The capital, Aracaju, displayed the highest seroprevalence. Surveys like this one are important to understand how the virus spreads and to help authorities to plan measures to control it. Repeated serologic testing are required to track the progress of the epidemic.

AbstractState of the art upper limb prostheses offer up to six active DoFs (degrees of freedom) and are controlled using different grip patterns. This low number of DoFs combined with a machine-human-interface which does not provide control over all DoFs separately result in a lack of usability for the patient. The aim of this novel upper limb prosthesis is both offering simplified control possibilities for changing grip patterns depending on the patients’ priorities and the improvement of grasp capability. Design development followed the design process requirements given by the European Medical Device Directive 93/42 ECC and was structured into the topics mechanics, software and drive technology. First user needs were identified by literature research and by patient feedback. Consequently, concepts were evaluated against technical and usability requirements. A first evaluation prototype with one active DoF per finger was manufactured. In a second step a test setup with two active DoF per finger was designed. The prototype is connected to an Android based smartphone application. Two main grip patterns can be preselected in the software application and afterwards changed and used by the EMG signal. Three different control algorithms can be selected: “all-day”, “fine” and “tired muscle”. Further parameters can be adjusted to customize the prosthesis to the patients’ needs. First patient feedback certified the prosthesis an improved level of handling compared to the existing devices. Using the two DoF test setup, the possibilities of finger control with a neural network are evaluated at the moment. In a first user feedback test, the smartphone based software application increased the device usability, e.g. the change within preselected grip patterns and the “tired muscle” algorithm. Although the overall software application was positively rated, the handling of the prosthesis itself needs to be proven within a patient study to be performed next. The capability of the neural network to control the hand has also to be proven in a next step.

Objective: To compare serum Anti Müllerian Hormone (AMH) levels in infertile women with and without endometriosis, and to determine the mean levels of serum AMH in every stage of endometriosis. Method: We performed a cross-sectional study. Sixty-eight subjects who have undergone laparoscopy and fulfilled both inclusion and exclusion criteria are recruited consecutively. They are divided into two groups, namely group with endometriosis and without endometriosis. Blood samples are taken from each subject before laparoscopy, where serum AMH levels are then measured. The difference in mean levels of each group are tested with Mann-Whitney test. Result: The mean levels of serum AMH were significantly lower in the endometriosis group than those in the group without endometriosis (2.30 1.8 ng/ml vs 3.75 2.13 ng/ml; p=0.005). Using Kruskal-Wallis test, it was found that there was a statistically significant difference among endometriosis groups based on the severity of endometriosis. There was no significant difference in the mean serum AMH levels between the minimal-mild endometriosis group and without endometriosis group (p=0.34), but the mean levels of serum AMH were significantly lower in the moderate-severe endometriosis compare to the group without endometriosis (p

Background: As part of the process of improving prosthetic arms, it is important to obtain the opinions of the user population.Objectives: To identify factors that should be focused on to improve prosthesis provision.Study design: Postal questionnaire.Methods: The questionnaire was sent to 292 adults (aged 18 to 70 years) with upper-limb loss or absence at five centres (four in Europe) Participants were identified as regular attendees of the centres.Results: This questionnaire received a response from 180 users (response rate 62%) of different types of prosthetic devices. Responses showed that the type of prosthesis generally used was associated with gender, level of loss and use for work (Pearson chi-square, p-values below 0.05). The type of prosthesis was not associated with cause, side, usage (length per day, sports or driving) or reported problems. The findings did not identify any single factor requiring focus for the improvement of prostheses or prosthetic provision.Conclusions: Every part of the process of fitting a prosthesis can be improved, which will have an effect for some of the population who use their devices regularly. There is, however, no single factor that would bring greater improvement to all users.Clinical relevance Based on information gained from a broad range of prosthesis users, no single aspect of prosthetic provision will have a greater impact on the use of upper limb prostheses than any other. Efforts to improve the designs of prosthetic systems can cover any aspect of provision.

This review presents an analytical and comparative survey of upper limb prosthesis acceptance and abandonment as documented over the past 25 years, detailing areas of consumer dissatisfaction and ongoing technological advancements. English-language articles were identified in a search of Ovid, PubMed, and ISI Web of Science (1980 until February 2006) for key words upper limb and prosthesis. Articles focused on upper limb prostheses and addressing: (i) Factors associated with abandonment; (ii) Rejection rates; (iii) Functional analyses and patterns of wear; and (iv) Consumer satisfaction, were extracted with the exclusion of those detailing tools for outcome measurement, case studies, and medical procedures. Approximately 200 articles were included in the review process with 40 providing rates of prosthesis rejection. Quantitative measures of population characteristics, study methodology, and prostheses in use were extracted from each article. Mean rejection rates of 45% and 35% were observed in the literature for body-powered and electric prostheses respectively in pediatric populations. Significantly lower rates of rejection for both body-powered (26%) and electric (23%) devices were observed in adult populations while the average incidence of non-wear was similar for pediatric (16%) and adult (20%) populations. Documented rates of rejection exhibit a wide range of variance, possibly due to the heterogeneous samples involved and methodological differences between studies. Future research should comprise of controlled, multifactor studies adopting standardized outcome measures in order to promote comprehensive understanding of the factors affecting prosthesis use and abandonment. An enhanced understanding of these factors is needed to optimize prescription practices, guide design efforts, and satiate demand for evidence-based measures of intervention.
