[Translation, Adaptation, Reliability and Validity of the German Version of the Prosthesis Mobility Questionnaire 2.0 (PMQ) on Patients with Major Lower Limb Amputation]. / Übersetzung und transkulturelle Adaptation des Prosthesis Mobility Questionnaire 2.0 (PMQ) ins Deutsche und dessen Reliabilität und Validität bei Patienten mit Majoramputation der unteren Extremität.

PURPOSE: The aim of this prospective validation study was to translate the Prosthesis Mobility Questionnaire 2.0 (PMQ) into German based on a guideline, following by psychometric testing for its validity and reliability using classical test theory. METHODS: The PMQ was translated into German according to ISPOR guidelines using double forward and double backward translations, finalized by pilot testing (N=10). Subsequently, assessment of the validity and reliability was performed from March 2020 to August 2020 on N=61 patients with unilateral lower limb amputation. Construct validity was determined by using the German version of the Locomotor Capabilities Index-5 (LCI-5-D), the Rivermead Mobility Index (RMI), the Timed up and go Test (TUG), and K-levels. Cronbach's alpha was calculated to check internal consistency and discriminatory power was determined by item correlations. Test-retest reliability was calculated using ICC (2,1). Based on the ICC, the minimum detectable difference (MDC) was calculated. RESULTS: The translation process required small changes after the pilot test. The validation study was performed on N=61 patients (56.59±13.16 years, m/f=38/23). A mean PMQ of 26.23±8.89 points was achieved. Ceilings or floor effects for total score did not appear. Construct validity showed strong positive correlations to LCI-5-D (r=0.74, p<0.001), RMI (r=0.63 p<0.001) as well as k-levels (r=0.61 p<0.001) and moderate negative correlation to TUG (r=- 0.49, p<0.001). Internal consistency was excellent with Cronbach's alpha=0.95). All items showed a value greater than r=0.40 for item-to-total score correlation. Test-retest reliability was excellent with an ICC (2,1)=0.98 with a timespan between T0 and T1 of 3.2±2.83 days. Based on this results, the MDC was 3.40 points. CONCLUSION: The German version of the Prosthesis Mobility Questionnaire 2.0 is a valid, reliable patient reported outcome measure (PROM) for measuring mobility and functional ability of patients with exoprosthesis due to unilateral lower limb amputation. It can be used for a German-speaking population.

"Fit for work and life": an innovative concept to improve health and work ability of employees, integrating prevention, therapy and rehabilitation.

OBJECTIVES: To set up a comprehensive health programme for employees, with needs-based allocation to preventive and rehabilitative measures; and to evaluate the effects of the programme on work ability and sick leave. DESIGN: Prospective single-group observational study. METHODS: Employees of a university hospital were invited to participate in needs-based interventions of preventive or rehabilitative character. Allocation followed screening questionnaires, anamnesis and clinical examination. The selection of a preventive or rehabilitative measure appropriate to the needs of the patient followed screening questionnaires, anamnesis and clinical examination. Preventive offers can include back training courses, water gymnastics or stress management exercises. Rehabilitative measures can include 3-6 weeks in- or outpatient rehabilitation or one week intensive outpatient rehabilitation. The main outcome parameters were work ability and sick leave duration. RESULTS: At this time of the project included 1,547 participants, who applied voluntarily to enter the programme. The mean age of participants was 44.3 years (standard deviation (SD) 10.3 years), and 72.0% were female. Needs-based allocation to a prevention (n=1,218) or a rehabilitation group (n=329) was effective, and enabled formation of 2 groups with different needs. Overall, more than half of the employees participating in the programme reported sick leave within the last 3 months. Participants in the preventive measures group reported significantly lower duration of sick leave than those in the rehabilitation group. Employees in the rehabilitation group had significantly lower work ability (Work Ability Index (WAI) 30.4 vs 36.6), but higher effects at 6-month follow-up (WAI 33.4 (standardized effect size (SES) 0.51) vs 37.9 (SES 0.17)). In the prevention group mean sick leave reduced significantly from 1.9 to 1.3 weeks (p < 0.001) during the previous 3-month period, whereas in the rehabilitation group it reduced from 2.7 to 1.5 (p < 0.001) weeks. CONCLUSION: Implementation of the comprehensive health programme was successful, using the multimodal infrastructure of a university hospital. Allocation to suitable interventions in occupational health programmes following screening, anamnesis and clinical examination is an appropriate way to meet participants' needs. The programme resulted in improved work ability and less sick leave.

Assessment of rehabilitation needs in patients after COVID-19: Development of the COVID-19-rehabilitation needs survey.

OBJECTIVE: COVID-19 can result in a broad spectrum of dysfunctions, some of which may persist for long periods, requiring long-term rehabilitation. A comprehensive screening tool is therefore necessary to identify these needs. To date, no data exist on satisfaction with medical and therapeutic interventions for COVID-19 in terms of quality and quantity. The aim of this study is to develop a survey for use with COVID-19 patients during and after the end of the acute phase of the disease. METHODS: Following the definition of dimensions by a group of experts, and a literature search, proven survey instruments were searched for suitable items. In addition, specific questions were developed based on symptoms, and answer options were created with regard to to the complexity of the questions. RESULTS: The COVID-19 Rehabilitation Needs Survey (C19-RehabNeS) consists of the established 36-item Short Form Survey (SF-36) together with the newly developed COVID-19-Rehabilitation Needs Questionnaire (C19-RehabNeQ) (11 further dimensions, respectively 57 items). CONCLUSION: C19-RehabNeS is a comprehensive survey to assess functional limitations and rehabilitation needs during and after infection with SARS-CoV-2 (COVID-19). The strength of this survey is that it combines the assessment of important rehabilitation needs with assessment of satisfaction with the health services, treatment and therapy during the pandemic (C19-RehabNeQ) and assessment of patients' quality of life (SF-36). The C19-RehabNeS survey also enables collection of systematic information on patients with Post-COVID-19 syndrome (Long-COVID-19).

Teaching functioning, disability and rehabilitation to first year medical students.

BACKGROUND: Many patients have disabilities; it is therefore essential that medical education includes comprehensive teaching on disability and rehabilitation. In 2006 Hannover Medical School implemented an introductory course in the curriculum for medical students, on how to communicate with persons with disability and the need for rehabilitation. The course, entitled "Introduction to medicine", has the main goals of teaching the strategy and systematic approach of medicine to solving patients' problems. METHODS: This paper describes the content, methods and outcomes of 1 of the 4 main themes of the "Introduction to medicine" course; the theme "Pain and disability", which is covered in the second week of the course. RESULTS: Evaluation of the "Pain and disability" module found that students' ratings for the category "patient involvement" were very high (93%), whereas their ratings for the category "examination of student knowledge" were low. The overall rating of the module was "good" (10.8 out of 15 points), but not "very good". CONCLUSION: The concept of the "Pain and disability" module is feasible and successful, even though it is scheduled early in the first year of the curriculum and approximately 350 students participate. Factors related to this success are: a mixture of teaching knowledge, supporting students' understanding, and applying communication and physical examination skills.

Preoperative femoral abduction angle correlates with initial postoperative lateral hip pain after transcutaneous osseointegrated prosthetic system (TOPS) in transfemoral amputees.

PURPOSE: To analyse whether a preoperative femoral abduction angle (FAA) correlates with postoperative initial lateral hip pain (LHP) in above-knee amputees (AKA) treated with transcutaneous osseointegrated prosthetic system (TOPS). METHODS: Pre- and postoperative long-leg radiographs of eighteen unilateral AKA (mean age 51.55y ± 12.16) were retrospectively measured. FAA was measured on both sides. Pain intensity of LHP was measured by numeric rating scale (NRS) preoperatively and every week for four weeks from the first day of weight loading. Pearson's r was calculated for correlation. Furthermore, odds ratio for LHP ≥ 5/10 NRS and relative FAA > 13° was calculated. RESULTS: FAA significantly decreased in the postoperative period (pre/post. 15.33° ± 4.22; p < 0.001). Median LHP was 0/10 NRS (min.0, max.3) preoperatively and 4/10 NRS (min.2, max. 7, p < 0.001) postoperatively after first loading. Interestingly, it decreased within four weeks to a median of 0.5/10 NRS (min.0, max. 3) without intervention. A strong correlation was seen on the amputated side between preoperative FAA and LHP after loading (r = 0.835, p < 0.001), as well as the relative FAA to LHP after loading (r = 0.732, p < 0.001) and between the gap of pre- to postoperative FAA and LHP. Odds ratio for LHP ≥ 5/10 and relative FAA > 13° was 6.4 (95%CI = 0.55; 74.89). CONCLUSION: The preoperative FAA strongly correlates with postoperative LHP. Surgeons should be aware of high risk of LHP that can limit prosthetic training. High preoperative FAAs should be realised in the decision meeting of TOPS implantation and pre-rehabilitative reduction of the FAA should be taken into consideration.

[Factors Influencing Access to Follow-Up Rehabilitation]. / Einflussfaktoren auf den Zugang in die Anschlussrehabilitation (AR/AHB).

PURPOSE: Identification of patient-related influencing factors on access to follow-up rehabilitation METHODS: Partially standardized, written survey of patients between the ages of 18 and 65 in 3 acute hospitals in Hanover, who were assigned to one of the following six defined indication groups on the basis of their diagnosis: (1) surgically treated bone fractures, (2) knee and hip endoprosthesis, (3) malignant disease from visceral surgery, (4) heart disease without surgical intervention, (5) heart disease with surgical intervention, and (6) stroke. In addition to personal information (such as age and gender) personal rehabilitation goals, rehabilitation motivation, disease processing, functioning, state of health, the knowledge of right to request and suffrage and the personal desire to start a follow-up rehabilitation were raised. RESULTS: Of the 1,227 patients surveyed, 42.5% received follow-up rehabilitation. The percentages between the groups of diagnoses varied widely and were lowest after conservatively treated heart disease (3.2%) and highest after knee and hip joint replacement (98.1%). Including cases with a follow-up rehabilitation relevant diagnosis (n=1,000), the proportion of persons with rehabilitation increased to 51.7% (p<0.001). Reasons for an untreated follow-up rehabilitation were in rare cases the rejection by the payer (0.7%), the rejection by the patient (1.6%) or the lack of rehabilitation ability (3.3%). However in most cases the application remained without further differentiation (28.5%). The most important factor influencing follow-up rehabilitation access were diagnosis. Compared to knee- and hip endoprosthesis, the patients from other relevant diagnosis groups had a much lower chance to start a follow-up rehabilitation (OR from 0,01 up to 0,07; p<0,001). The desire of the patient showed the second most and significant influence to get follow-up rehabilitation (OR=8.18; p<0.001). CONCLUSIONS: The diagnosis was identified as the most important criterion for follow-up rehabilitation access. No measurable factors of functioning seem to have a big influence. Therefore, the individual doctor's decision to submit an application is of particular importance. Especially because of the low level of medical knowledge on the indication catalog of the German pension insurance, the medical treatment based on professional experience as well as the lack of further education possibilities (Gottschling-Lang, 2016), it can be assumed that the follow-up rehabilitation is less standardized and systematic. In order to ensure a need-based patient care, assessment procedures should be established and the training and continuing education of physicians should be supplemented with the topic of follow-up rehabilitation.

The IASP classification of chronic pain for ICD-11: functioning properties of chronic pain.

Physical, mental, and social well-being are part of the concept of health according to the World Health Organization, in addition to the absence of disease and infirmity. Therefore, for a full description of a person's health status, the International Classification of Functioning, Disability and Health (ICF) was launched in 2001 to complement the existing International Classification of Diseases (ICD). The 11th version of the ICD (ICD-11) is based on so-called content models, which have 13 main parameters. One of them is functioning properties (FPs) that, according to the WHO, consist of the activities and participation components of the ICF. Recently, chronic pain codes were added to the 11th edition of the ICD, and hence, a specific set of FPs for chronic pain is required as a link to the ICF. In addition, pain is one of the 7 dimensions of the generic set of the ICF, which applies to any person. Thus, assessment and management of pain are also important for the implementation of the ICF in general. This article describes the current consensus proposal by the International Association for the Study of Pain (IASP) and the International Society of Physical and Rehabilitation Medicine (ISPRM) for a specific set of FPs of chronic pain, which will have to be empirically validated in a next step. The combined use of ICD-11 and ICF is expected to improve research reports on chronic pain by a more precise and adequate coding, as well as patient management through better diagnostic classification.

The effectiveness of a population-based skin cancer screening program: evidence from Germany.

In this paper, we analyze how a nationwide population-based skin cancer screening program (SCS) implemented in Germany in 2008 has impacted the number of hospital discharges following malignant skin neoplasm diagnosis and the malignant melanoma mortality rate per 100,000 inhabitants. Our panel data, drawn from the Eurostat database, cover subregions in 22 European countries, measured at the lowest nomenclature of territorial units for statistics (NUTS) level for 2000-2013. Applying fixed effects methods, we find a significantly positive and robust effect of the German SCS on the number of patients diagnosed with malignant skin neoplasm. However, the program does not significantly influence the melanoma mortality rate. This finding conflicts with the decreased melanoma mortality rate found for the pilot SCS program in northern Germany. Our results indicate that Germany's nationwide SCS program is effective in terms of a higher diagnosis rate for malignant skin neoplasms and thus may contribute to an improvement in the early detection of skin cancer.

Hannover model for the implementation of physical and rehabilitation medicine teaching in undergraduate medical training.

As any patient may require rehabilitation and physical therapies, all physicians need to acquire at least a basic knowledge of Physical and Rehabilitation Medicine (PRM). In 2005 PRM teaching was implemented in all phases of the curriculum for medical students in Germany. The curriculum includes, among others, the following topics: principles of rehabilitation; the model of the International Classification of Functioning, Disability and Health (ICF); principles and effects of physiotherapy and occupational therapy; indications and contraindications for PRM interventions. Teaching of PRM topics is implemented from the first week in all phases of the curriculum, as: (i) lectures in the module "Introduction to Medicine (Propaedeuticum)"; (ii) a cross-sectional course entitled "Rehabilitation, Physical Medicine and Naturopathic Treatment (RPMN)"; (iii) single lectures on PRM in other fields; (iv) elective mandatory courses on the social model of rehabilitation, balneology, and others; and (v) the option to choose PRM as a subject for practical training. All modules are evaluated regularly by the students. Global ratings of the module "Propaedeuticum" were good, and of the cross-sectional course "RPMN" very good. The advanced part of the practical training was rated highly by the students. In conclusion, the implementation of teaching of PRM and other rehabilitation topics in undergraduate medical education is a successful concept that fulfils the criteria for education in medical school set out by the American Association of Academic Physiatrists.

Prospective investigation into the influence of various stressors on skin impedance.

BACKGROUND: The control mechanisms during general anesthesia include circulation parameters and vegetative reactions. A possible way to quantify vegetative reactions is to measure the impedance of the skin. An activation of the eccrine sweat glands via sympathetic sudomotor fibers induces a secretion of sweat, which generates a drop in skin impedance. The aim of the present study was to investigate the influence which different stressors and measurement electrodes have upon skin impedance. MATERIAL AND METHOD: The changes in skin impedance and were measured after application of various stimuli (T1 value at rest, T2 acoustic stimulus, T3 visual stimulus, T4 tactile stimulus, T5 pain stimulus, T6 Valsalva manoeuvre, T7 forced inspiration/expiration). About 62 awake subjects underwent four standardized test sequences, during which several types of electrodes and recording sites (palmarly, plantarly) were explored. RESULTS: All physiological (T6-T7) and external stimuli (T2-T5) led to significant changes in skin impedance (14.9 +/- 18.2 kOmega) and heart rate. These changes happened independently of BMI, gender and measurement electrode types. The time it took to react to the stimuli was significantly shorter for palmar applications than that obtained from plantar sites. The reaction times were as follows: palmarly 1.2 +/- 0.5 seconds for solidgel electrodes and 1.15 +/- 0.5 seconds for hydrogel electrodes, plantarly 2.3 +/- 1.0 seconds for solidgel electrodes and 2.21 +/- 1.2 seconds for hydrogel electrodes. The forced inspiration and expiration manoeuvres generated greater variations in skin impedance than did pain stimulus and acoustic stimulus. Measurements that were performed with solidgel electrodes revealed significantly greater average decreases in skin impedance following exposure to a stimulus. CONCLUSION(S): External, but primarily also physiological stressors, generate direct and reproducible variations in skin impedance. Solidgel ECG electrodes should be used for all measurements.
