Skin problems of the stump and hand function in lower limb amputees:A historic cohort study

The aim of this study was to investigate the relationship between liner-related skin problems of the stump in patients with a lower limb amputation and impaired hand function. Sixty patients who were treated in a rehabilitation hospital from 1998-2006 were included in an historic cohort study. Data were collected concerning the amputation, skin problems of the stump, co-morbidity, hand function, the prosthesis, liner use and mobility score. The study population consisted of 50 trans-tibial and 10 knee disarticulation amputees, 43 male and 17 female, with a mean age of 62.3 years. The majority (63%) had a vascular reason for amputation. Blisters, folliculitis, rash and surface wounds on the stump were operationalized as being liner related. In patients with an impaired hand function, 70% had experienced liner-related skin problems of the stump, whereas 32% of the patients with a normal hand function had experienced skin problems (p=0.035). This study shows that impaired hand function poses an increased risk for skin problems in the amputation stump in patients with a lower limb amputation and liner use in their prosthesis.</p

Feasibility and short-term effects of Activity Coach+:a physical activity intervention in hard-to-reach people with a physical disability

Purpose: Existing physical activity interventions do not reach a considerable proportion of physically disabled people. This study assessed feasibility and short-term effects of Activity Coach+, a community-based intervention especially targeting this hard-to-reach population. Methods: Feasibility was determined by reach, dropouts, and compliance with the protocol. Physical activity was measured with the Activ8 accelerometer and the adapted SQUASH questionnaire. Health outcomes were assessed by body composition, blood pressure, hand grip force, 10-metre walk test, 6-minute walk test, and the Berg Balance Scale. The RAND-36, Exercise Self-Efficacy Scale, Fatigue Severity Scale, and IMPACT-S were administered. Measurements were performed at baseline and after 2 and 4 months. Changes over time were analysed by Friedman tests. Results: Twenty-nine participants enrolled during the first 4 months, of whom two dropped out. Intervention components were employed in 86–100% of the participants. Physical activity did not change after the implementation of Activity Coach+. Body mass index (p = 0.006), diastolic blood pressure (p = 0.032), walking ability (p = 0.002), exercise capacity (p = 0.013), balance (p = 0.014), and vitality (p = 0.049) changed over time. Conclusions: Activity Coach + is feasible in a community setting. Indications for effectivity of Activity Coach + in hard-to-reach people with a physical disability were found.Implications for rehabilitation Activity Coach + was able to reach physically disabled people living in community, a population that is assumed hard-to-reach. Activity Coach + was feasible in a population of persons with a physical disability that was heterogeneous with respect to age and (severity of) disability. The current study provides the first indications for the beneficial health effects of Activity Coach + in hard-to-reach people with a physical disability

The assessment of efforts to return to work in the European Union

Background: Assessment of efforts to promote return-to-work (RTW) includes all efforts (vocational and non-vocational) designed to improve the work ability of the sick-listed employee and increase the chance to return to work. Aim of the study was to investigate whether in 13 European countries these RTW efforts are assessed and to compare the procedures by means of six criteria. METHODS: Data were gathered in the taxonomy project of the European Union of Medicine in Assurance and Social Security and by means of an additional questionnaire. RESULTS: In seven countries RTW efforts are subject of the assessment in relation to the application for disability benefits. Description of RTW efforts is a prerequisite in five countries. Guidelines on the assessment of RTW efforts are only available in the Netherlands and no countries report the use of the ICF model. Based on the results of the additional questionnaire, the assessor is a social scientist or a physician. The information used to assess RTW efforts differs, from a report on the RTW process to medical information. A negative outcome of the assessment leads to delay of the application for disability benefits or to application for rehabilitation subsidy. Conclusion: RTW efforts are assessed in half of the participating European countries. When compared, the characteristics of the assessment of RTW efforts in the participating European countries show both similarities and differences. This study may facilitate the gathering and exchange of knowledge and experience between countries on the assessment of RTW efforts

Reliability of Clinician Rated Physical Effort Determination During Functional Capacity Evaluation in Patients with Chronic Musculoskeletal Pain

Introduction Functional capacity evaluation (FCE) can be used to make clinical decisions regarding fitness-for-work. During FCE the evaluator attempts to assess the amount of physical effort of the patient. The aim of this study is to analyze the reliability of physical effort determination using observational criteria during FCE. Methods Twenty-one raters assessed physical effort in 18 video-recorded FCE tests independently on two occasions, 10 months apart. Physical effort was rated on a categorical four-point physical effort determination scale (P-ED) based on the Isernhagen criteria, and a dichotomous submaximal effort determination scale (S-ED). Cohen's Kappa, squared weighted Kappa and % agreement were calculated. Results Kappa values for intra-rater reliability of P-ED and S-ED for all FCE tests were 0.49 and 0.68 respectively. Kappa values for inter-rater reliability of P-ED for all FCE tests in the first and the second session were 0.51, and 0.72, and for S-ED Kappa values were 0.68 and 0.77 respectively. The inter-rater reliability of P-ED ranged from kappa = 0.02 to kappa = 0.99 between FCE tests. Acceptable reliability scores (kappa > 0.60, agreement a parts per thousand yen80 %) for each FCE test were observed in 38 % of scores for P-ED and 67 % for S-ED. On average material handling tests had a higher reliability than postural tolerance and ambulatory tests. Conclusion Dichotomous ratings of submaximal effort are more reliable than categorical criteria to determine physical effort in FCE tests. Regular education and training may improve the reliability of observational criteria for effort determination

Mortality, Reamputation, and Preoperative Comorbidities in Patients Undergoing Dysvascular Lower Limb Amputation

Background: Historically, mortality rates after major lower limb amputations (LLAs) have been very high. However, there are inconsistencies regarding the risk factors. The reamputation rate after major LLAs is largely unknown. The aim of this study is to report the 30-day and 1-year mortality and 1-year reamputation rates after major LLA and to identify potential risk factors.Methods: An observational cohort study in which all patients undergoing dysvascular major LLA in 2012-2013 in 12 hospitals in the northern region of the Netherlands is included.Results: Of total 382 patients, who underwent major LLA, 65% were male and the mean age (standard deviation [SD]) was 71.9 +/- 12.5 years. Peripheral arterial disease was observed in 88% and diabetes mellitus (DM), in 56% of patients. No revascularization or prior LLA on the amputated side was observed among 26%, whereas 56% had no minor or major LLA on either limb before the study period. The 30-day and 1-year mortality rates were 14% and 34%, respectively. Patients aged 75-84 and &gt;85 years had 3-4 times higher odds of dying within 1 year. Transfemoral amputations (odds ratio [OR], 2.2), history of heart failure (OR, 2.3), myocardial infarction (OR, 1.7), hemodialysis (OR, 5.7), immunosuppressive medication (OR, 2.8), and guillotine amputations (OR, 5.1) were independently associated with 1-year mortality. Twenty-six percent underwent ipsilateral reamputation within 1 year, for which no risk factors were identified.Conclusions: The mortality rate in the first year after major LLA is high, particularly among those undergoing transfemoral amputations, which is likely to be indicative of more severe vascular disease. Higher mortality among the most elderly patients, those with more severe cardiac disease and who underwent hemodialysis reflects the frailty of this population. Interestingly, DM, revascularization history, and prior minor or major LLA were not associated with mortality rates.</p

Staying at work with chronic nonspecific musculoskeletal pain:a qualitative study of workers' experiences

BACKGROUND: Many people with chronic nonspecific musculoskeletal pain (CMP) have decreased work ability. The majority, however, stays at work despite their pain. Knowledge about workers who stay at work despite chronic pain is limited, narrowing our views on work participation. The aim of this study was to explore why people with CMP stay at work despite pain (motivators) and how they manage to maintain working (success factors). METHODS: A semi-structured interview was conducted among 21 subjects who stay at work despite CMP. Participants were included through purposeful sampling. Interviews were audio-recorded, transcribed verbatim, and imported into computer software Atlas.ti. Data was analyzed by means of thematic analysis. The interviews consisted of open questions such as: "Why are you working with pain?" or "How do you manage working while having pain?" RESULTS: A total of 16 motivators and 52 success factors emerged in the interviews. Motivators were categorized into four themes: work as value, work as therapy, work as income generator, and work as responsibility. Success factors were categorized into five themes: personal characteristics, adjustment latitude, coping with pain, use of healthcare services, and pain beliefs. CONCLUSIONS: Personal characteristics, well-developed self-management skills, and motivation to work may be considered to be important success factors and prerequisites for staying at work, resulting in behaviors promoting staying at work such as: raising adjustment latitude, changing pain-coping strategies, organizing modifications and conditions at work, finding access to healthcare services, and asking for support. Motivators and success factors for staying at work may be used for interventions in rehabilitation and occupational medicine, to prevent absenteeism, or to promote a sustainable return to work. This qualitative study has evoked new hypotheses about staying at work; quantitative studies on staying at work are needed to obtain further evidence

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

Grip strength is strongly associated with height, weight and gender in childhood:a cross sectional study of 2241 children and adolescents providing reference values

QuestionWhat are reference values for grip strength in children and adolescents based on a large and heterogeneous study population? What is the association of grip strength with age, gender, weight, and height in this population?DesignCross-sectional study.ParticipantsParticipants were recruited from schools in the northern provinces of the Netherlands. The study included healthy children and adolescents ranging in age from 4 to 15 years.Outcome measuresAll children had their height (cm) and weight (kg) measured and were allowed a total of four attempts using the Jamar hand dynamometer: twice with each hand. Grip strength scores (kg) were recorded for the dominant and non-dominant hands.ResultsThe study population comprised 2241 children and adolescents. Reference values for both genders are provided according to age and dominance. Grip strength shows a linear and parallel progression for both genders until the age of 11 or 12, after which grip strength development shows an acceleration that is more prominent in boys.ConclusionThere is a significant difference in grip strength with each ascending year of age in favour of the older group, as well as a trend for boys to be stronger than girls in all age groups between 4 and 15 years. Weight and especially height have a strong association with grip strength in children

Physical activity in children with Juvenile Idiopathic Arthritis compared to controls

BACKGROUND: To compare physical activity (PA) in children with juvenile idiopathic arthritis (JIA) with controls and to analyse the effect of disease specific factors on PA in children with JIA treated according to current treatment regimes. METHODS: PA was measured with a 7-day activity diary and expressed as physical activity level (PAL). Moderate to vigorous physical activity (MVPA) (hours/day) and sedentary time (hours/day) was determined. In children with JIA, medication, the number of swollen and/or painful joints, disease activity, functional ability, pain and well-being was determined. Multivariate regression analysis was performed to analyze differences in PA between JIA and controls, adjusted for influences of age, gender, season, Body Mass Index (BMI) and to analyze predictors of PA in JIA patients. RESULTS: Seventy-six children with JIA (26 boys and 50 girls, mean ± SD age 10.0 ± 1.4 years) and 131 controls (49 boys and 82 girls, mean ± SD age 10.4 ± 1.2 years) participated in this study. Children with JIA had a significantly lower PAL (0.10, p = 0.01) corrected for age, BMI, gender and season. They spent less time in MVPA (0.41 h/day, p = 0.06) and had a significantly higher mean time spent in sedentary activities (0.59 h/day, p 0.02) compared to controls. The activity level of children with JIA was related to age, gender, season, feeling of well-being and pain. CONCLUSION: Children with JIA have a lower PAL, spent less time in MVPA and spent more time on sedentary activities compared to controls despite current medical treatment and PA encouragement. TRIAL REGISTRATION: Data of the children with JIA are from the Rheumates@work study ISRCTN92733069
