Background: The lateral elbow tendinopathy is a common injury in tennis players and physical workers. The Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire was specifically designed to measure pain and functional limitations in patients with lateral epicondylitis (tennis elbow). First developed in English, this questionnaire has since been translated into several languages. Objectives: The aims of the study were to translate and cross-culturally adapt the PRTEE questionnaire into French and to evaluate the reliability and validity of this translated version of the questionnaire (PRTEE-F). Methods: The PRTEE was translated and cross-culturally adapted into French according to international guidelines. To assess the reliability and validity of the PRTEE-F, 115 participants were asked twice to fill in the PRTEE-F, and once the Disabilities of Arm, Shoulder and Hand questionnaire (DASH) and the Short Form Health Survey (SF-36). Internal consistency (using Cronbach’s alpha), test-retest reliability (using intra-class correlation coefficient (ICC), Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC)), and convergent and divergent validity (using the Spearman’s correlation coefficients respectively with the DASH and with some sub scales of the SF-36) were assessed. Results: The PRTEE was translated into French without any problems. PRTEE-F showed a good test-retest reliability for the overall score (ICC 0.86) and for each item (ICC 0.8-0.96) and a high internal consistency (Cronbach’s alpha = 0.98). The correlation analyses revealed high correlation coefficients between PRTEE-F and DASH (convergent validity) and, as expected, a low or moderate correlation with the divergent subscales of the SF-36 (discriminant validity). There was no floor or ceiling effect. Conclusions: The PRTEE questionnaire was successfully cross-culturally adapted into French. The PRTEE-F is reliable and valid for evaluating French-speaking patients with lateral elbow tendinopathy. [less ▲]

Purpose The Victorian Institute of Sport Assessment – Achilles tendinopathy questionnaire (VISA-A) evaluates the clinical severity of Achilles tendinopathy. The aim of this study was to translate the VISA-A into French and to study the reliability and validity of this French version, the VISA-AF. Method The VISA-A was translated into French to produce the VISA-AF using a validated methodology in six steps. Thereafter, several psychometric properties of this French version such as test–retest reliability, internal consistency, construct validity and floor and ceiling effects were evaluated. Therefore, we recruited 116 subjects, distributed into 3 groups: pathological patients (n¼31), at-risk athletes (n¼63) and healthy people (n¼22). Results The final version of the VISAAF was approved by an expert committee. On a scale ranging from 0 to 100, the average scores of the VISA-AF obtained were 59 (± 18) for the pathological group, 99 (± 1) for the healthy group and 94 (± 7) for the at-risk group. The VISA-AF shows excellent reliability, low correlations with the discriminant subscales of the SF-36 and moderate correlations with the convergent subscales of the SF-36. Conclusions The French version of the VISA-A is equivalent to its original version and is a reliable and valid questionnaire for French-speaking patients with Achilles tendinopathy. [less ▲]

Background : The aims of this study were to evaluate the effect of a single PRP injection followed by a standardized reeducation protocol among patients suffering from different tendinopathies, but otherwise healthy, and to determine the biomarkers that constitute good prognosis factors, if any. Methods : 48 patients suffering from different tendinopathies and refractory to conventional physiotherapy were treated with a single PRP injection. Prior to the injection, a blood sample was drawn and some biological parameters (glycemia, cholesterolemia,...) were measured. A pain assessment was then made using a Visual Analog Scale of pain (VAS) and a pressure algometer. The same assessment was carried out after 6 weeks and 12 weeks when possible. Results : There is an overall significant improvement in VAS score at the end of the 12 weeks follow- up. However, no correlation was found between the evolution of the clinical scores and the biological parameters measured. Conclusion: A PRP injection followed by a program of eccentric rehabilitation positively affects the algo-functional scores of patients with tendinopathies who were refractory to conventional physio- therapy, whatever the initial values of the measuured biological parameters.

BACKGROUND Classification criteria are recommended for diseases that lack highly specific biomarkers in order to improve homogeneity in clinical research. Since imaging evidence of lumbar spinal stenosis (LSS) or lumbar disc herniations (LDH) may not be associated with symptoms, clinical classification criteria based upon patient symptoms and physical examination findings are required. This study sought to develop a set of criteria identifying patients with neurogenic claudication (NC) caused by LSS and patient with radicular pain (RP) caused by LDH. This abstract reports the results concerning NC caused by LSS. METHODS Phase 1: Nineteen spine specialists (clinicians and researchers) from 8 countries participated in a Delphi process, using an internet program, to rank symptoms and signs which suggest LSS as the cause of NC or DH as the cause of RP. Phase 2: Nineteen different spine specialists (surgeons and non-surgeons) from 5 countries recruited patients during office visits and classify them with a high degree of confidence as having with either: 1) NC caused by LSS 2) RP caused by LDH or 3) non-specific low back pain (NSLBP) with non-specific leg pain radiation. Patients completed survey items and specialists documented examination signs. Signs and symptoms present in ≥ 10 patients were analyzed by using Generalized Estimating Equations (GEE). Patients with NC caused by LSS or NSLBP served as controls. Items with p<0.1 in univariate analysis were entered in the multivariate analysis. A score to predict NC caused by LSS was developed based on the coefficient of the GEE, and used to obtain a ROC curve and the associated area under the curve (AUC). RESULTS A list of 46 clinical signs and 28 patient-reported symptoms were selected by the group of spine specialists during the 1st phase. For the 2nd phase, 209 patients with high confidence in the diagnosis were included 63 NC caused by LSS, 89 RP caused by DH, and 57 NSLBP with non-specific leg pain radiation. Items which predicted NC with a p-value <0.1 included age >60, bilateral leg pain, leg pain relieved by sitting, leg pain decreased by leaning or flexing, positive30 seconds extension test, negative straight leg raise test. The score had an AUC of 0.91, and the cutoff to obtain a specificity of 92.1% resulted in a sensitivity of 80.0%. CONCLUSION An international collaboration of surgeon and non-surgeon spine specialists produced a set of diagnostic criteria with high specificity and sensitivity for identifying patients with NC caused by LSS. Using this set could improve the quality of basic science and clinical research in this field by improving homogeneity within groups of patients. [less ▲]

Contexte: L’épicondylite latérale est une blessure commune chez les joueurs de tennis et les travailleurs physiques pour qui il existe un questionnaire en anglais qui en évalue la sévérité. Le questionnaire « Patient-Rated Tennis Elbow Evaluation » (PRTEE) mesure la douleur et l’incapacité fonctionnelle du coude chez les patients souffrant d’une épicondylite latérale. Le questionnaire a déjà été traduit en suédois, en turc, en québécois, en italien, en néerlandais et en grec. Objectifs : Le but de cette étude est de traduire et de réaliser une adaptation interculturelle du questionnaire PRTEE en français et d’en évaluer sa fiabilité et sa validité. Matériel et Méthodes : Le PRTEE a été adapté interculturellement en français selon les lignes directrices internationales. Les participants (n=115) ont rempli le PRTEE-F, deux fois avec un intervalle de 30 minutes, le questionnaire Disabilities of Arm, Soulier and Hand (DASH), et le Short Form Health Survey (SF-36) pour évaluer la fiabilité et la validité du PRTEE-F. La cohérence interne (avec l’alpha de Cronbach), la fidélité test-retest (avec la corrélation intra-classe (ICC)) et la validité de construit (avec le coefficient de corrélation de Spearman). Résultats : Le PRTEE-F montre une fidélité test-retest bonne pour le score total (ICC 0,83) et pour les différents items (ICC 0,71-0,9). La traduction française possède une cohérence interne élevée (0,98). La corrélation entre le PRTEE-F et le DASH est forte pour le score total (rs=0,92, p<0.001), pour le sous-total symptomatique (rs=0,86, p<0.001) et fonctionnel (rs=0,93, p<0.001). Le PRTEE-F possède une corrélation forte avec une partie des sous-échelles convergentes du SF-36 (PF, RP et BP). Il y a une corrélation faible ou modérée avec les sous-échelles divergentes du SF-36 (REm, MH, SF et VT). Il n’y a pas d’effet plancher et plafond. Conclusion : La version française du questionnaire PRTEE a été adaptée interculturellement avec succès, et cette étude a montré que le PRTEE-F est fiable et valide pour évaluer les patients francophones souffrant d’une épicondylite latérale.

Introduction : La reconstruction du ligament croisé antéro-externe du genou est une chirurgie lourde qui est suivie d’une longue période de rééducation. Le retour au sport après cette opération reste toutefois un défi. Plus d’un tiers des athlètes est incapable de reprendre son activité au même niveau. La peur de subir un nouvel accident reste un obstacle majeur à cette reprise sportive et la persistance de déficits fonctionnels est la première cause de récidives de déchirure ligamentaire. Matériels et méthodes : Notre échantillon comprend dix sujets, cinq dans le groupe bénéficiant d’une réathlétisation précoce et cinq dans le groupe témoin. Le premier groupe réalise une séance de réathlétisation précoce hebdomadaire (à raison d’une fois par semaine et ce, durant six mois) associée à la rééducation en kinésithérapie durant une durée de six mois. Le deuxième groupe bénéficie uniquement de séances de kinésithérapie classique respectant un protocole bien défini du CHU de Liège. Nous avons choisi de réaliser, en pré-opératoire, dans les deux groupes, un test isocinétique. En post-opératoire (après six mois), les sujets des deux groupes ont réalisé dans l’ordre suivant : un test isocinétique, un questionnaire de KOOS et enfin des tests fonctionnels (Hop test). Les séances de réathlétisation et de kinésithérapie sont suivies selon un protocole spécifique respectant l’individualisation propre à chaque patient. Résultats : L’analyse des tests isocinétiques et du questionnaire de KOOS, nous a permis de constater des différences entre les deux groupes au niveau des valeurs chiffrées mais qui ne sont cependant pas significatives (P level= 0,07). Par contre, l’analyse des résultats obtenus dans les tests fonctionnels (tests de sauts en longueur évaluant la performance en distance) a montré des différences significatives (P level= 0,04 pour le single hop et le triple hop test, P level= 0,02 pour le cross over hop test) entre les deux groupes et celles-ci sont au bénéfice du groupe ayant bénéficié d’une réathlétisation précoce. Conclusion : Dans cette étude, nous constatons une amélioration globale des performances en faveur du groupe ayant bénéficié d’une réathlétisation précoce. Cependant lors de l’analyse statistique et ce surtout concernant dans le test isocinétique, peu d’éléments évoluent de manière significative voir aucun pour le questionnaire de KOOS. Le faible échantillonnage de cette étude préliminaire intervient certainement dans ce constat. [less ▲]

BACKGROUND: Regular physical activity is an important health factor, but intense physical stress can increase the risk of heart disease. OBJECTIVE: Our aim was to determine the potential cardiac repercussions of, and the oxidative stress resulting from a maximal eccentric isokinetic exercise and a 1-hour treadmill run at 75% ˙V O2 max (maximal exercise done 6 weeks before). METHODS: Twelve young sedentary healthy subjects randomly performed two tests separated by 6 weeks: 1) 3 sets of 30 maximal eccentric isokinetic contractions of the quadriceps; 2) a 1-hour running on treadmill at 75% ˙V O2 max. We drew blood samples just before each exercise (T1), and just after (T2), 3 hours after (T3), and 24 hours after (T4) the end of each exercise to measure cardiac and oxidative stress biomarkers. RESULTS: In the running group, we observed significant differences for myoglobin (T3: 145 ± 80 μg/L), creatinine kinase (T4: 593 ± 350 mg/L), oxidized glutathione (T2: 22 ± 15.6 μmol/L), and highly sensitive cardiac troponin T, (T3: 0.051 ± 0.038 ng/mL). In the isokinetic group, we observed significant differences for myoglobin (T3:1419 ± 2533 mg/L), creatine kinase (3303 ± 7159 mg/L), and oxidized glutathione (T4:24 ± 14 μmol/L). Between isokinetic exercise and running, we observed significant differences for uric acid (p < 0.05, running > eccentric), myoglobin (p < 0.05, ditto), NT-proBNP (p < 0.05, ditto), hsTnT (p < 0.01, ditto), and oxidized glutathione (p < 0.05). CONCLUSIONS: As cardiac biomarkers appear practically unmodified after the isokinetic exercise, despite the considerable oxidative stress, we suggest that the application of intense maximal eccentric isokinetic exercise, when indicated, should be safe for most patients including those whose cardiac status is unknown. On the other hand, the increase in cardiac biomarkers observed after running, could reflect leakage of these biomarkers from the cytosolic pool of cardiac cells, linked to membrane damage, rather than the result of a major injury and hence running is supposed to be a safe practice. However, since sudden death during running has been previously described, assesment of the cardiac biomarkers and a follow-up by a sport doctor is important especially if there is a cardiac family history.

Objectives: Over the past two decades, a large interest in cardiac marker elevations has developed in endurance sports events. The intense effort is not without risk. We aim to see if the relatively cardiospecific biomarkers could show the damage on cardiac muscle cells. Methods: Fourteen cyclists were recruited for an international race (177km). We studied the release of injury related cardiac markers, risk related cardiac markers, renal function markers and blood cytology. The subjects were submitted to three blood test: one before (T0), one just after (T1) and the last one 3 hours after the race (T3). Results: Blood cytology markers, namely erythrocytes, hemoglobin, hematocrit, and average hemoglobin concentration, were found to evolve in a similar way. Renal function markers, such as creatinin, cystatin C and uric acid, showed a post effort increase that might be related to renal blood flow depletion during exercise. Cardiac and muscular markers were all increased at T1. Conclusions: Physiological stress induced by an international cycling race certainly has consequences on cardiac muscle cells. Fortunately, those blood concentration variations are more representative of a transitional state, due to an imbalance created by an intense aerobic effort maintained during several hours, rather than an irreversible injury.

Background: The lateral elbow tendinopathy is a common injury in tennis players and physical workers. The Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire was created to measure pain and functional disabilities specifically reported in patient with lateral epicondylitis (tennis elbow). Developed in English, this questionnaire has since then been translated into several languages but not in French. Objectives: The aims of the study were to translate and cross-culturally adapt the PRTEE questionnaire into French and to evaluate the reliability and validity of this new version of the questionnaire (PRTEE-F). Methods: The PRTEE was cross-culturally adapted into French according to the international guidelines. To assess the reliability and validity of the PRTEE-F, 115 participants filled in the PRTEE-F twice, and the Disabilities of Arm, Shoulder and Hand questionnaire (DASH) and the Short Form Health Survey (SF-36) once. Internal consistency (with Cronbach’s alpha), test-retest reliability (with intra-class correlation (ICC)), convergent and divergent validity (by calculating the Spearman’s correlation coefficients with the DASH and some sub scales of the SF-36, respectively) were assessed. Results: The PRTEE was translated in French without problem. PRTEE-F showed a good test-retest reliability for the overall score (ICC 0.83) and for each items (ICC 0.71-0.9) and a high internal consistency (Cronbach’s alpha = 0.98). The correlation analyses revealed high correlation coefficients between PRTEE-F and DASH (good convergent validity) and, as expected, a low or moderate correlations with the divergent subscales of the SF-36 (discriminant validity). There was no floor or ceiling effect. Conclusions: The PRTEE questionnaire was successfully cross-culturally adapted into French the PRTEE-F is reliable and valid for evaluating the French-speaking patient with lateral elbow tendinopathy.

Objectives. While moderate exercise has beneficial effects on the cardiovascular system, consequences of a supra-physiological effort are not clear yet. In particular, the physiological consequences of ultramarathons need to be further documented. The aim of the study was to assess the changes of various cardiac biomarkers after a mountain ultra-marathon. Material and methods. Blood and urine samples were collected on 28 runners (17 men) participating to the Ultra-Trail du Mont Blanc (105km, total positive elevation: 5600 m) at 3 different times: before the race (Pre), within 1 h after the finish (Post) and 7 days after the finish (D+7). Several biomarkers involved in heart disease (coronary syndrome, heart failure and fibrosis) and in inflammation were assayed on different analyzers such a COBAS® (for CKMB,TnThs, NT-proBNP, H-FABP and CRPs) and KRYPTOR® (for Copeptin). ST2 was measured manually with the Presage kit from CRITICAL DIAGNOSTIC®. Results. Plasma levels of cardiac markers (CKMB, TnThs, NT-proBNP, copeptin, H FABP, ST2) and inflammation (CRPs) increased significantly at Post. Means values increased from Pre to Post as follows: 2.3 to 91.9 UI/L for CKMB (p<0.0001); 7.6 to 31.7 ng/L for TnThs (p<0.0001); 41.7 to 1190.5 ng/L for NT-proBNP, 4.2 to 22.9 pmol/L for copeptin (p=0.001); 3.6 to 107.8 ng/mL for H-FABP (p<0.0001), 29.7 to 126.2 ng/mL for ST2 (p<0.0001); 0.5 to 29.1 mg/L for CRPs (p<0.0001). With the exception of a few (H-FABP, ST2, CRPs) biomarkers in some subjects, all values were back to Pre values at D+7. Discussion-conclusion. Prolonged strenuous running exercise caused an elevation in cardiac biomarkers. Elevation in CK-MB levels lacks specificity for cardiac damage as runners have increased CKMB from skeletal muscles as well. Previous studies suggested that exercise induced TnThs elevation is a benign reversible physiologic phenomenon but this parameter, as well as H-FABP, could be a sign of ischemia. Different phenomena occurred such as stretch of myocytes causing an increase in pressure or volume and neurohormonal activation which can explain the Copeptine and NT-proBNP increase, while ST2 is a biomarker of cardiac remodeling and fibrosis. CRP is an acute phase compound that tends to increase following a strenuous and prolonged bout of exercise and/or muscular injury. As the values tended to return within the normal reference range values within 7 days after the race, our study suggests that there is no permanent structural damage at the myocardium level.
