[Contribution of physical and rehabilitation medicine to primary care medicine]. / Apport de la médecine physique et de réadaptation à la médecine de premier recours.

Physical and rehabilitation medicine (PRM) is an independent medical specialty, little known in Switzerland. This specialty, strongly linked to the holistic approach of the International Classification of Functioning, will be increasingly solicited by the epidemiology of disability and the imperatives of "ageing better". Its skills in prescribing human and material resources for rehabilitation provide added value in terms of loss of autonomy. Based on a biopsychosocial model, PRM has a high role to play in prevention and primary healthcare, as well as in the management and prevention of the consequences of functionally limiting diseases. There are, however, financial (pricing) and demographic (lack of representation) obstacles to effective action on behalf of the population and the healthcare system.

La médecine physique et de réadaptation (MPR), discipline indépendante, est peu connue en Suisse. Cette spécialité, liée à l'approche holistique de la classification internationale du fonctionnement, sera de plus en plus sollicitée par l'épidémiologie du handicap et les impératifs du « vieillir mieux ¼. Ses compétences de prescription des moyens humains et matériels en réadaptation apportent une plus-value sur la perte d'autonomie. Basée sur un modèle biopsychosocial, la MPR trouve sa place dans la prévention et les soins de santé primaires ainsi que dans la prise en charge et la prévention des conséquences des maladies induisant une limitation fonctionnelle. Il existe toutefois des obstacles financiers (tarification) et démographiques (insuffisance de représentation) pour une action efficace au service de la population et du système de santé.

Reduction in pain-related fear is not associated with improvement in spinal biomechanics but with decrease in movement-evoked pain in patients with chronic low back pain.

BACKGROUND AND AIMS: While a causal relationship between pain-related fear and spinal movement avoidance in patients with chronic low back pain (CLBP) has frequently been postulated, evidence supporting this relationship is limited. This study aimed to test if decreases in pain-related fear or catastrophizing were associated with improvements in spinal biomechanics, accounting for possible changes in movement-evoked pain. METHODS: Sixty-two patients with CLBP were assessed before and after an interdisciplinary rehabilitation program (IRP). Pain-related fear was assessed with general and task-specific measures. Lower and upper lumbar angular amplitude and velocity as well as paraspinal muscle activity were recorded during five daily-life tasks to evaluate spinal biomechanics. Relationships were tested with multivariable linear regression analyses. RESULTS: The large decreases in pain-related fear and catastrophizing following the IRP were scarcely and inconsistently associated with changes in spinal biomechanics (< 3% of the models reported a statistically significant association). Results remained comparable for activities inducing more or less fear, for specific or general measures of pain-related fear, and for analyses performed on the entire population or limited to subgroups of patients with higher levels of task-specific fear. In contrast, reductions in task-specific pain-related fear were significantly associated with decreases in movement-evoked pain in all tasks (r = 0.26-0.62, p ≤ 0.02). CONCLUSION: This study does not support an association between pain-related fear and spinal movement avoidance. However, it provides evidence supporting a direct relationship between decreased pain-related fear and decreased movement-evoked pain, possibly explaining some mechanisms of the rehabilitation programs.

Impact of early sports specialisation on paediatric ECG.

Athletes of pediatric age are growing in number. They are subject to a number of risks, among them sudden cardiac death (SCD). This study aimed to characterize the pediatric athlete population in Switzerland, to evaluate electrocardiographic findings based on the International Criteria for electrocardiography (ECG) Interpretation in Athletes, and to analyze the association between demographic data, sport type, and ECG changes. Retrospective, observational study of pediatric athletes (less than 18 years old) including medical history, physical examination, and a 12-lead resting ECG. The primary focus was on identification of normal, borderline, and abnormal ECG findings. The secondary observation was the relation between ECG and demographic, anthropometric, sport-related, and clinical data. The 891 athletes (mean 14.8 years, 35% girls) practiced 45 different sports on three different levels, representing all types of static and dynamic composition of the Classification of Sports by Mitchell. There were 75.4% of normal ECG findings, among them most commonly early repolarization, sinus bradycardia, and left ventricular hypertrophy; 4.3% had a borderline finding; 2.1% were abnormal and required further investigations, without SCD-related diagnosis. While the normal ECG findings were related to sex, age, and endurance sports, no such observation was found for borderline or abnormal criteria. Our results in an entirely pediatric population of athletes demonstrate that sex, age, and type of sports correlate with normal ECG findings. Abnormal ECG findings in pediatric athletes are rare. The International Criteria for ECG Interpretation in Athletes are appropriate for this age group.

Are patients with hypermobile Ehlers-Danlos syndrome or hypermobility spectrum disorder so different?

Diagnosing hypermobile Ehlers-Danlos syndrome (hEDS) remains challenging, despite new 2017 criteria. Patients not fulfilling these criteria are considered to have hypermobile spectrum disorder (HSD). Our first aim was to evaluate whether patients hEDS were more severely affected and had higher prevalence of extra-articular manifestations than HSD. Second aim was to compare their outcome after coordinated physical therapy. Patients fulfilling hEDS/HSD criteria were included in this real-life prospective cohort (November 2017/April 2019). They completed a 16-item Clinical Severity Score (CSS-16). We recorded bone involvement, neuropathic pain (DN4) and symptoms of mast cell disorders (MCAS) as extra-articular manifestations. After a standardized initial evaluation (T0), all patients were offered the same coordinated physical therapy, were followed-up at 6 months (T1) and at least 1 year later (T2), and were asked whether or not their condition had subjectively improved at T2. We included 97 patients (61 hEDS, 36 HSD). Median age was 40 (range 18-73); 92.7% were females. Three items from CSS-16 (pain, motricity problems, and bleeding) were significantly more severe with hEDS than HSD. Bone fragility, neuropathic pain and MCAS were equally prevalent. At T2 (20 months [range 18-26]) 54% of patients reported improvement (no difference between groups). On multivariable analysis, only family history of hypermobility predicted (favorable) outcome (p = 0.01). hEDS and HDS patients showed similar disease severity score except for pain, motricity problems and bleeding, and similar spectrum of extra-articular manifestations. Long-term improvement was observed in > 50% of patients in both groups. These results add weight to a clinical pragmatic proposition to consider hEDS/HSD as a single entity that requires the same treatments.

[Plantar fasciitis: update 2021]. / Aponévropathie plantaire : mise au point 2021.

Plantar heel pain affects 4 to 9% of the population and is a common reason for consultation. Plantar fasciitis is the most frequent cause. Its diagnosis is essentially clinical, possibly supported initially by combination of X-ray/ultrasound. Ultrasound is the modality of choice to confirm the diagnosis. The prognosis is favorable, but the evolution can be long. Its management should be structured in a progressive manner, based on therapeutic education and physical measures. These simple measures have the highest level of evidence of effectiveness and should be implemented before proposing, sometimes too early, second-line therapies.

Les talalgies plantaires touchent 4 à 9 % de la population et sont un motif fréquent de consultation en médecine générale et en médecine du sport. L'aponévropathie plantaire en est la cause la plus fréquente. Son diagnostic est essentiellement clinique, éventuellement complété en première intention par le couple radiographie/échographie. Cette dernière est l'examen de choix permettant de confirmer le diagnostic. De pronostic favorable, sa durée d'évolution peut être longue. Sa prise en charge doit être structurée de façon progressive en s'appuyant sur l'éducation thérapeutique et des mesures physiques. Ces mesures simples montrent le niveau de preuve d'efficacité le plus élevé et doivent impérativement être mises en place avant de proposer, parfois trop précocement, des thérapeutiques de seconde intention.

"Minimal clinically important difference" estimates of 6 commonly-used performance tests in patients with chronic musculoskeletal pain completing a work-related multidisciplinary rehabilitation program.

BACKGROUND: Functional tests are widely used to measure performance in patients with chronic musculoskeletal pain. Our objective was to determine the Minimal Clinically Important Differences (MCID) for the 6-min walk test (6MWT), the Steep Ramp Test (SRT), the 1-min stair climbing test (1MSCT), the sit-to-stand test (STS), the Jamar dynamometer test (JAM) and the lumbar Progressive Isoinertial Lifting Evaluation (PILE) in chronic musculoskeletal pain patients. METHODS: A single-center prospective observational study was conducted in a rehabilitation center. Patients with upper-limb, lower-limb or neck/back lesions were included over a period of 21 months. We used the anchor-based method as a reference method, supplemented by the distribution-based and opinion-based approaches, to determine the MCIDs. RESULTS: 838 chronic musculoskeletal pain patients were included. The estimation method and thelesion location had a significant influence on the results. MCIDs were estimated at +75m and +60m for the 6MWT (lower-limb and neck/back lesions, respectively), +18 steps for the 1MSCT (lower-limb and neck/back lesions) and +6kg for the JAM (upper limb lesions). The anchor-based method could not provide valid estimations for the three other scales, but distribution and opinion-based methods provided rough values of MCIDs for the SRT (+39w to +61w), the STS (-5 sec to -7 sec) and the PILE (+4kg to +7kg). CONCLUSION: The above MCID estimations for the 6MWT, 1MSCT and JAM can be used in chronic musculoskeletal pain patients participating in vocational multidisciplinary rehabilitation programs or in therapeutic trials. The use of specific anchors might give better estimations of MCIDs for the three other scales in future research.

[Leg pain : differential diagnosis and treatment]. / Douleurs de la jambe : diagnostic différentiel et traitement.

Acute or chronic leg pain is a common reason for consultation. It is not a specific symptom and several potential causes have to be considered. Both functional and vital prognosis can be engaged. The diagnosis is often based on patient history and clinical examination, whereas the overuse of complementary investigations can lead to confusion. A good knowledge of anatomy, as well as the different etiologic entities, is essential to evaluate acute or chronic leg pain and to guide the diagnostic and therapeutic strategies.

Les douleurs aiguës ou chroniques de la jambe sont un motif fréquent de consultation. Il s'agit d'un symptôme souvent peu spécifique et plusieurs étiologies sont à considérer. Le pronostic fonctionnel du membre ainsi que le pronostic vital peuvent être engagés. Le diagnostic repose souvent sur l'anamnèse et l'examen clinique, alors que la multiplication d'examens complémentaires peut augmenter la confusion diagnostique. Une bonne connaissance de l'anatomie de la jambe, ainsi que des différents cadres étiologiques est indispensable à l'évaluation de ces douleurs et permet de guider la démarche diagnostique et thérapeutique.

[Place of interdisciplinary treatments in chronic low back pain]. / Place du traitement interdisciplinaire intensif dans la lombalgie chronique.

The treatment of chronic lumbar pain patients needs a global interdisciplinary approach when traditional conservative treatments do not fulfil their aims. One of the most efficient ways to proceed is using an interdisciplinary treatment program, including physiotherapeutic measures, occupational therapy and psychological support for 3 weeks. It is important that people in conflicts with insurances companies should be excluded from these treatments. It is also important that the reconditioning should continue over a long term to have a sustainable result.

La prise en charge de la lombalgie chronique nécessite une approche globale interdisciplinaire quand les approches traditionnelles n'apportent pas l'effet escompté. Une des manières les plus efficaces d'y arriver est par le biais de groupes de rééducation fonctionnelle durant 3 semaines. Ces approches englobent une prise en charge physique, ergothérapeutique et psychologique. Ces groupes permettent souvent de relancer des situations complexes, si d'autres conflits ­ comme par exemple, des conflits assécurologiques ­ sont absents. Il reste aussi important de poursuivre un reconditionnement sur le long terme pour avoir un résultat durable.

[What do we know about the exercise-related transient abdominal pain ?] / Que sait-on sur le « point de côté ¼ lié à l'effort ?

Exercise-related transient abdominal pain or « side stitch ¼ is a very common problem among athletes, whatever their level of participation. This pain may be present in different areas of the abdomen, even in the shoulder, usually well localized, and described as cramping or stabbing depending on the severity. The etiology is still debated, with many possible theories. It is a benign problem but other pathologies, often more severe, must be excluded in case of any atypical presentation. There are simple preventive measures recommended. This pain usually disappears within minutes by slowing or stopping the effort and / or using different methods without scientific validation until now.

La douleur abdominale transitoire liée à l'effort ou « point de côté ¼ est un problème fréquemment rencontré chez les sportifs, qu'ils soient débutants ou confirmés. Cette douleur peut être présente dans différentes zones de l'abdomen, voire même les épaules, le plus souvent bien localisée, décrite comme une crampe ou « coup de couteau ¼ selon la sévérité. L'étiologie est encore débattue, avec de multiples théories possibles. Il s'agit d'un problème bénin mais d'autres pathologies, souvent plus graves, doivent être exclues devant toute présentation atypique. Il existe des mesures préventives simples à conseiller. Cette douleur disparaît généralement en quelques minutes en ralentissant ou stoppant l'effort et / ou à l'aide de différentes méthodes, sans validation scientifique à ce jour.

A study of the 200-metre fast walk test as a possible new assessment tool to predict maximal heart rate and define target heart rate for exercise training of coronary heart disease patients.

OBJECTIVE: To develop a new predictive model of maximal heart rate based on two walking tests at different speeds (comfortable and brisk walking) as an alternative to a cardiopulmonary exercise test during cardiac rehabilitation. DESIGN: Evaluation of a clinical assessment tool. SETTING: A Cardiac Rehabilitation Department in France. SUBJECTS: A total of 148 patients (133 men), mean age of 59 ±9 years, at the end of an outpatient cardiac rehabilitation programme. MAIN MEASURES: Patients successively performed a 6-minute walk test, a 200 m fast-walk test (200mFWT), and a cardiopulmonary exercise test, with measure of heart rate at the end of each test. An all-possible regression procedure was used to determine the best predictive regression models of maximal heart rate. The best model was compared with the Fox equation in term of predictive error of maximal heart rate using the paired t-test. RESULTS: Results of the two walking tests correlated significantly with maximal heart rate determined during the cardiopulmonary exercise test, whereas anthropometric parameters and resting heart rate did not. The simplified predictive model with the most acceptable mean error was: maximal heart rate = 130 - 0.6 × age + 0.3 × HR200mFWT (R(2) = 0.24). This model was superior to the Fox formula (R(2) = 0.138). The relationship between training target heart rate calculated from measured reserve heart rate and that established using this predictive model was statistically significant (r = 0.528, p < 10(-6)). CONCLUSIONS: A formula combining heart rate measured during a safe simple fast walk test and age is more efficient than an equation only including age to predict maximal heart rate and training target heart rate.

Changes in spinal motor behaviour are associated with reduction in disability in chronic low back pain: A longitudinal cohort study with 1-year follow-up.

BACKGROUND: The need to improve spinal motor behaviour in chronic low back pain (CLBP) rehabilitation remains unclear. The objective of this study was to test if changes in spinal motor behaviour were associated with changes in disability after an interdisciplinary rehabilitation program (IRP) in patients with CLBP. METHODS: Seventy-one patients with CLBP participating in an IRP were included. Spinal motor behaviour was assessed with biomechanical (lumbar angular amplitude and velocity, erector spinae muscle activity and duration of the task), cognitive-emotional (task-specific fear [PRF]) and pain-related (movement-evoked pain [MEP]) measures during a lifting task before and after the IRP. Disability was measured before and after the IRP, and at 3-month and 1-year follow-ups. RESULTS: After adjusting for confounders, changes in disability were significantly associated with MEP changes (ß adj. = 0.49, p < 0.001) and PRF changes (ß adj. = 0.36, p = 0.008), but not with changes in any of the biomechanical measures. MEP at the end of IRP was also associated with disability at 3 months (ß adj. = 0.37, p = 0.001) and 1 year (ß adj. = 0.42, p = 0.01). Biomechanical measures at the end of the IRP were not associated with disability, except for the duration of the task that was significantly associated with reduction of disability at 3 months (ß non-adj = 0.5, p < 0.001). CONCLUSIONS: Pain-related and cognitive-emotional measures of spinal motor behaviour were associated with reduction in disability following an IRP. Future research is needed to further investigate causal relationships between spinal motor behaviour and disability. SIGNIFICANCE STATEMENT: This study supports a multidimensional understanding and analysis of spinal motor behaviour, integrating the cognitive-emotional, pain-related and biomechanical domains. It also supports the consideration of spinal motor behaviour as a potentially important treatment target in chronic low back pain management. Moreover, it suggests that reducing movement-evoked pain and task-specific fear may have more influence on disability than changing lumbar amplitude, lumbar angular velocity or erector muscle activity, which may have important implications for rehabilitation.

Clinical Applications of Virtual Reality in Musculoskeletal Rehabilitation: A Scoping Review.

(1) Background: VR is based on a virtual world that creates sounds effects and videos that replace the real environment. Arising literature shows VR efficacy in the field of neurological rehabilitation (NR) and that its use is also taking a place in musculoskeletal rehabilitation (MSR), as a treatment of various disorders that cause disability and chronic pain. (2) Aim: We discuss the role of VR in MSR, presenting its use and development on acute and chronic musculoskeletal disorders, based on the most recent literature. (3) Design and Methods: Literature searches were conducted in the databases Pubmed and Medline up to 30 September 2023. The PRISMA-Scr Checklist was followed. (4) Results: A total of 51 records were included. The analysed studies were conducted within a variety of populations, musculoskeletal disorders, settings, and VR technologies. Only a few studies could statistically affirm the efficacy of VR in MSR, as mentioned for the rehabilitation of the upper limb. Nevertheless, the observed trend is an improvement of the global perceived effect compared to traditional rehabilitation. (5) Conclusion: VR allows for the personalisation of treatment with an adaptable treatment platform, which may improve the participation of the patient and increase acceptability and adherence to long-term rehabilitation programs. We provide recommendations and suggestions for future research and use of VR in musculoskeletal rehabilitation.

Short-term effects on heart rate variability of occipito-mastoid suture normalization in healthy subjects.

Occipito-mastoid structure normalization (OMSN) is an osteopathic manipulative treatment aimed at reducing tension around the jugular foramen, where cranial nerves IX, X, and XI exit the skull. The purpose of this study was to observe how heart rate variability (HRV), a marker of autonomic cardiac regulation, was modulated after an OMSN vs. a sham technique (SHAM). Pre- and post-intervention HRV was analyzed in two randomly chosen groups of 15 participants (OMSN vs. SHAM group). HRV was collected in the supine position 5 min before and 5 min after a 10-min application of either OMSN or SHAM. The time and group effect was analyzed using a two-way ANOVA. Independently from group intervention, a significant time effect induced increased HRV. No group effect differences were observed. Multiple comparisons for time and group interaction showed that the root mean square of successive differences (RMSSD), a vagally mediated HRV variable, increased to a greater extent for the OMSN group (p = 0.03) than for the SHAM group. However, both OMSN and SHAM techniques had a significant effect on HRV. Compared to a SHAM technique, OMSN had a significant effect on HRV vagally related metric RMSSD in the short term. We conclude that 10 min of OMSN may be used to induce a short-term influence on parasympathetic autonomic nervous system modulations.

Development and Validation of Short Forms of the Pain Catastrophizing Scale (F-PCS-5) and Tampa Scale for Kinesiophobia (F-TSK-6) in Musculoskeletal Chronic Pain Patients.

Purpose: Chronic pain is a complex phenomenon. Understanding its multiple dimensions requires the use of a combination of several patient-reported outcome measures (PROMs). However, completing multiple PROMs is time-consuming and can be a burden for patients. The objective of our study was to simultaneously reduce the French versions of the Pain Catastrophizing Scale (PCS) and Tampa Scale for Kinesiophobia (TSK) questionnaires to enable their use in an ambulatory and clinical settings. Patients and Methods: We conducted a clinical study between May 2014 and August 2020 in our rehabilitation center. 1428 chronic musculoskeletal pain patients (CMSP) were included. The originality of our approach is that the reduction method included qualitative as well as quantitative analyses. The study was divided into two parts: 1) reduction of the questionnaires (n=1363) based on internal consistency (item-to-total correlation), principal component analysis (item loadings), Rasch analysis (infit/outfit), floor and ceiling effect (quantitative analyses) and expert judgment of items (qualitative analysis), and 2) validation of the reduced questionnaires (n=65), including test-retest reliability (intraclass correlation coefficient [ICC]), homogeneity (Cronbach α), criterion validity (Pearson correlation [r] with the long-version score), determination of the pathological cutoff and Minimal Clinically Important Difference (MCID). The two full-length questionnaires include 30 items in total. Results: The reduction resulted in a 5-item PCS (score 0-20) and 6-item TSK (score 0-24). Psychometric properties of the reduced questionnaires were all acceptable as compared with other version (α=0.89 and 0.71, ICC=0.75 and 0.60, r=0.86 and 0.70, MCID=2 and 2 for PCS and TSK, respectively) while keeping the structure and coherence of the long versions. Conclusion: The two reduced versions of the PCS and TSK can be used in CMSP patient. As their administration only requires a few minutes, they can be implemented in outpatient consultation as well as in clinical settings.

Simple clinical tools improve ability-to-work predictions for individuals 3-24 months after upper limb injury.

BACKGROUND: Despite numerous previous studies, predicting the ability to work (ATW) after an upper limb injury (ULI) remains difficult for those still not working 3-24 months after their initial injury. OBJECTIVES: We aimed to identify simple prognostic characteristics that were associated with the long-term ATW for individuals who remained unable to work several months after the accident that caused their ULI. METHODS: A single-center prospective observational study in a rehabilitation center in the French-speaking part of Switzerland. We included participants who were 18-60 years old, still unable to work because of persistent pain/disability 3-24 months after an ULI, and who were referred to our rehabilitation center for a 1-month intensive interdisciplinary treatment. Data were collected on personal characteristics, body function/structure variables, activity limitations/participation restrictions, and environmental factors. Participants' evolution during rehabilitation was assessed using functional tests/questionnaires and the 7-level self-reported Patient's Global Impression of Change (PGIC) assessment at discharge. Participant outcomes after 1 year were categorized as either able (ATW>0%) or unable (ATW=0%) to work. The best prognostic characteristics were selected by logistic regression analysis. RESULTS: Among the 317 participants, 202 (64%) had an ATW>0% at 1 year. A grip strength ≥16 kg (Jamar Hand Dynamometer score - affected side) and "(I) do not take pain medicine" were independent predictors. Overall, 96% (26/27) of participants with these 2 characteristics had an ATW>0% at 1 year. The simultaneous absence of these characteristics predicted an unfavorable prognosis in 50% (59/119) of participants. For those who also had a positive PGIC score then 100% (25/25) of participants with these 3 characteristics had an ATW>0%; for those without, only 42% (19/45) had an ATW>0%. CONCLUSIONS: Grip strength (≥16 kg) and not taking pain medicine are favorable prognostic factors for an ATW after an ULI. Their absence is associated with a poor ATW prognosis for half of people with ULI and should alert caregivers to risk of long-term absenteeism ("red flags"). Including data from a PGIC further improves the ATW prediction. We recommend that these 3 criteria be systematically evaluated.

Poststroke disposition and associated factors in a population-based study: the Dijon Stroke Registry.

BACKGROUND AND PURPOSE: The organization of poststroke care will be a major challenge in coming years. We aimed to assess hospital disposition after stroke and its associated factors in clinical practice. METHODS: All cases of stroke from 2006 to 2010 were identified from the population-based Stroke Registry of Dijon, France. Demographic features, risk factors, and prestroke treatments were recorded. Admission stroke severity was assessed using the National Institutes of Health Stroke Scale score. At discharge, we collected dementia, disability using the modified Rankin Scale, length of stay, and hospital disposition (home, rehabilitation, convalescent home, and nursing home). Multivariate analyses were performed using logistic regression models to identify associated factors of postdischarge disposition. RESULTS: Of the patients with 1069 stroke included, 913 survived acute care. Among them, 433 (47.4%) returned home, whereas 206 (22.6%) were discharged to rehabilitation, 134 (14.7%) were admitted to a convalescent home, and 140 (15.3%) to a nursing home. Old patients, those under anticoagulants before stroke, those with severe stroke on admission, severe disability at discharge, dementia, or prolonged length of stay were less likely to return home. Moreover, advanced age, severe initial stroke, severe disability at discharge, and dementia were associated with admission to convalescent and nursing homes rather than rehabilitation centers. CONCLUSION: This population-based study demonstrated that postdischarge destinations are associated with several factors. Our findings may be useful to establish health policy concerning the organization of poststroke care.

Construction and pilot assessment of the Upper Limb Assessment in Daily Living Scale.

OBJECTIVE: The upper limb function of hemiplegic patients is currently evaluated using scales that assess physical capacity or daily activities under test conditions. The present scale, the Upper Limb Assessment in Daily Living (ULADL) Scale, was developed to explore the subjective and objective functional capacities of such patients in a proximal to distal sequence. METHODS: A group of experts constructed a scale addressing 17 upper limb functions (five active passive and 12 active) which could be explored by a questionnaire (Q) and a test (T). Reproducibility, internal consistency, concurrent validity (Rivermead Motor Assessment (RMA)) and learning effect were estimated in a multicentre study. RESULTS: 49 stroke patients were each rated three times within 7 days by a total of 21 physicians, yielding a total of 142 ratings. The ULADL took 16±8 min to complete compared with 9±5 min for the RMA. Cronbach's alpha coefficient was 0.95 for Q and 0.97 for the practical tests (T). The global Q and T scores, and in particular the global Q score, were slightly higher at the second rating. The intra-rater intraclass correlation coefficient (ICC) was 0.65 (95% CI (0.44 to 0.79)) for Q and 0.97 (0.95 to 0.98) for T, and the inter-rater ICC was 0.95 for both Q and T. The Bland and Altman method showed good intra- and inter-rater reliability with no systematic trend. Correlation coefficients for ULADL versus RMA were >0.80 for both Q and T. CONCLUSIONS: The ULADL Scale has good psychometric properties and can explore patients with different degrees of upper limb impairment.

Cognitive assessment scale for stroke patients (CASP): A multicentric validation study.

BACKGROUND: The Mini Mental State Examination and Montreal Cognitive Assessment are commonly used as short screening batteries for assessing cognitive impairment after stroke. However, aphasia or hemispatial neglect may interfere with the results. For this reason, we developed the Cognitive Assessment scale for Stroke Patients (CASP), which takes these conditions into consideration and previously demonstrated its superiority over these scales in terms of feasibility. OBJECTIVES: Our goal was to verify the psychometric properties of the (original) French version of the CASP. METHODS: We included 201 patients with a recent first hemispheric stroke and 50 controls. Stroke patients were examined 4 times (visit 1 [V1] to visit 4 [V4]) in the subacute post-stroke phase. The structural validity of the CASP was studied by principal factorial analysis, convergent validity by comparison with several variables including a comprehensive neuropsychological assessment, divergent validity by comparison with the total score between stroke patients and controls, and sub-scores between right and left stroke. Internal consistency, reproducibility and sensitivity to change were assessed. We propose the Minimal Clinically Important Difference (MCID) value and a pathological threshold as well as a threshold to predict cognitive change between V1 and V4. RESULTS: Of the 201 participants included (63% male; mean [SD] age 63 [13] years), CASP data were available for 199/150/133/93 at V1/V2/V3/V4, respectively. CASP has a one-dimensional structure. The hypotheses of convergent/divergent validities were confirmed. Internal consistency was good and reliability excellent. Responsiveness was small to moderate, but the MCID could still be estimated. We discuss the choice of a pathological threshold and a predictive threshold of V1 over V4. CONCLUSIONS: CASP has good psychometric properties for screening cognitive impairment in the subacute post-stroke phase, which is consistent with its Italian and Korean versions. It can be used for patients with severe motor aphasia or left hemispatial neglect but not in case of severe oral comprehension or visual impairment.

Short term high-intensity interval training in patients scheduled for major abdominal surgery increases aerobic fitness.

BACKGROUND: Prehabilitation may improve postoperative clinical outcomes among patients undergoing major abdominal surgery. This study evaluated the potential effects of a high-intensity interval training (HIIT) program performed before major abdominal surgery on patients' cardiorespiratory fitness and functional ability (secondary outcomes of pilot trial NCT02953119). METHODS: Patients were included before surgery to engage in a low-volume HIIT program with 3 sessions per week for 3 weeks. Cardiopulmonary exercise and 6-min walk (6MWT) testing were performed pre- and post-prehabilitation. RESULTS: Fourteen patients completed an average of 8.6 ± 2.2 (mean ± SD) sessions during a period of 27.9 ± 6.1 days. After the program, [Formula: see text]O2 peak (+ 2.4 ml min-1 kg-1, 95% CI 0.8-3.9, p = 0.006), maximal aerobic power (+ 16.8 W, 95% CI 8.2-25.3, p = 0.001), [Formula: see text]O2 at anaerobic threshold (+ 1.2 ml min-1 kg-1, 95%CI 0.4-2.1, p = 0.009) and power at anaerobic threshold (+ 12.4 W, 95%CI 4.8-20, p = 0.004) were improved. These changes were not accompanied by improved functional capacity (6MWT: + 2.6 m, 95% CI (- 19.6) to 24.8, p = 0.800). CONCLUSION: A short low-volume HIIT program increases cardiorespiratory fitness but not walking capacity in patients scheduled for major abdominal surgery. These results need to be confirmed by larger studies.

Determining the minimal clinically important difference for the six-minute walk test and the 200-meter fast-walk test during cardiac rehabilitation program in coronary artery disease patients after acute coronary syndrome.

OBJECTIVE: To estimate the minimal clinically important difference (MCID) for the 6-minute walk test (6MWT) and the 200-m fast-walk test (FWT) in patients with coronary artery disease (CAD) during a cardiac rehabilitation program. DESIGN: Prospective study using distribution- and anchor-based methods. SETTING: Outpatients from a cardiac rehabilitation unit. PARTICIPANTS: Stable patients with CAD (N=81; 77 men; mean±SD age, 58.1±8.7y) enrolled 31±12.1 days after an acute coronary syndrome (ACS). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: 6MWT and 200-m FWT results before and after an 8-week cardiac rehabilitation program and at the 6th and 12th sessions. Patients and physiotherapists who supervised the training were asked to provide a global rating of perceived change in walking ability while blinded to changes in walk test performances. RESULTS: Mean change in 6MWT distance (6MWD) in patients who reported no change was -6.5m versus 23.3m in those who believed their performance had improved (P<.001). This result was consistent with the MCID determined by using the distribution method (23m). Considering a 25-m cutoff, positive and negative predictive values were 0.9 and .63, respectively. Conversely, there was no difference in 200-m FWT performance between these 2 groups (0.1 vs -1.4s, respectively). There was poor agreement with the physiotherapist's perceived change. CONCLUSIONS: The MCID for 6MWD in patients with CAD after ACS was 25m. This result will help physicians interpret 6MWD change and help researchers estimate sample sizes in further studies using 6MWD as an endpoint.
