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 ▲]

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.

Le développement des activités sportives augmente la fréquence des lésions musculo-squelettiques de l’adolescent. Ces lésions dépendent non seulement du mécanisme mais également de l’âge du sportif et de sa maturation osseuse, particulièrement des noyaux d’ossification. Les aphophysoses, ostéochondroses ou ostéodystrophies se manifestent par une douleur au niveau de l’insertion tendineuse sur le noyau d’ossification secondaire en croissance. Elles sont souvent provoquées par des contraintes en traction-cisaillement chez des enfants sportifs entre 3 et 16 ans. L’excès pondéral constitue également un facteur de risque. La guérison spontanée s’observe généralement après trois à 12, voire 18 mois d’évolution. La maladie de Sever est l’ostéodystophie du pied la plus fréquente ; elle touche le noyau postérieur du calcanéum, qui apparaît entre sept et dix ans et qui fusionne à la fin de la puberté (16–18 ans) et sur lequel s’insèrent le tendon d’Achille et le court fléchisseur plantaire. Les contraintes en traction et compression (réception de saut) sont importantes à ce niveau surtout chez les sportifs de sept à 15 ans pratiquant diverses impulsions (basket-ball, volley-ball, saut en longueur. . . ). La talalgie se manifeste lors de la pratique sportive. La douleur est bilatérale dans 60% des cas. Il faut rechercher des troubles de statique plantaire (pieds creux) régulièrement associés à la maladie de Sever. Le bilan radiologique reste souvent décevant et peu spécifique. Le diagnostic différentiel doit s’établir avec une tendinopathie achilléenne, une fracture du calcaneus, un kyste osseux, un ostéome ostéoïde, une ostéomyélite ou une éventuelle enthésopathie (spondylarthropathie). La base du traitement est le repos sportif en phase algique, l’usage de la cryothérapie, le port de talonnettes amortissantes ou encore la prise temporaire d’AINS (ibuprofène). Au niveau du genou, l’apophysose de croissance la plus fréquente est la maladie d’Osgood-Schlatter qui est plus fréquente chez les adolescents pratiquant des sports de sauts. Au niveau du bassin tous les noyaux d’ossifications peuvent être atteints et même être le site de fractures-avulsions lors de contractions musculaires excessives ou brutales car le cartilage de croissance présente une faiblesse locale par rapport aux structures musculo-tendineuses. L’ostéochondrite disséquante correspond à un noyau osseux séparé du corps de l’os et recouvert de cartilage normal ; localisée à la partie supéromédiale du talus ou au niveau des condyles fémoraux. Elle est souvent asymptomatique, voire entraine une discrète limitation douloureuse de la mobilisation mais entraine une douleur à la palpation locale. Elle nécessite cependant un traitement adéquat. En cas de lésion peu ou pas évolutive, une surveillance radiologique (IRM / arthroscanner) est suffisante. Chez le très jeune adolescent une immobilisation plâtrée de six semaines permettrait la fusion du noyau (au niveau du dôme talien). L’arthroscopie sera justifiée en cas de séquestre osseux afin de l’extraire, et ce, avec de bons résultats postopératoires. L’ostéosynthèse d’un noyau volumineux peut être également indiquée, les résultats restant plus aléatoires. En conclusion, la pathologie traumatique ou microtraumatique de l’adolescent sportif n’est pas rare et ne doit jamais être négligée. Toute douleur exige une exploration radiologique comparative afin de poser un diagnostic précis et d’entreprendre un traitement adéquat, le plus souvent conservateur. [less ▲]

Study Design Clinical measurement study. Background The Victorian Institute of Sports Assessment–Patellar tendinopathy questionnaire (VISA-P), originally developed in English, assesses the severity of patellar tendinopathy symptoms. No French version of the questionnaire exists. Objectives The aim of our study was to translate the VISA-P in French and verify its psychometric properties. Methods The translation and cultural adaptation were performed according to international recommendations in six steps: initial translation, translation merging, back translation to the original language, expert committee to reach a pre-final version, test of the pre-final version, and expert committee appraisal of a final version. Afterwards, the psychometric properties the final French version (VISA-PF) were assessed in 92 subjects, divided into three groups: pathological subjects (n = 28), asymptomatic subjects (n = 22) and sports-risk subjects (n = 42). Results All members of the expert committee agreed with the final version. On a scale ranging from 0 to 100 (asymptomatic subject), the average scores of the VISA-PF obtained were 53 (± 17) for the pathological group, 99 (± 2) for the healthy group and 86 (± 14) for the sports-risk group. The test-retest reliability of the VISA-PF was excellent and good internal consistency. Correlations between the VISA-PF and diverging validity of the SF-36 were low and the correlation coefficient values measured between the VISA-PF scores and converged items of the SF-36 were higher. Conclusion The VISA-PF is understandable, valid and suitable for French-speaking patients with patellar tendinopathy. [less ▲]

Tendinopathy is a major problem in medicine and sports traumatology. It is due, inter alia, to mechanical overload. It remains a challenge for the medical world to the extent that its frequent resistance to conventional treatments never promises the patient a favourable response following therapeutic management. The development of platelet-rich plasma (PRP) is a new hope when therapeutic treatments such as NSAIDs, corticosteroid injections, eccentric rehabilitation, shock waves, etc. have shown their limits. Furthermore, since January 2011, it is no longer included on the list of doping substances (http://www.wada-ama.org/). Indeed, platelets contain various growth factors (PDGF, TGF-β, FGF, VEGF, HGF, IGF-1) which participate to the tendon healing process. PRP is obtained by centrifugation of autologous blood to obtain a platelet concentration greater than that of the blood, which varies according to the production method. PRP also contains a variable amount of lymphocytes and erythrocytes that can have a detrimental effect on wound healing. Currently, there is no formal consensus regarding the production method or the biological composition of PRP. Many laboratory studies (in vitro and/or on animal) emphasize the acceleration of the healing tendon process after injection of PRP, each growth factor exerting a specific action during healing. PRP would cause the proliferation, migration and differentiation of cells derived from circulation, improving the initial phase of the tendon healing. This anabolic process initiates the type I collagen synthesis. Although currently the effectiveness of PRP on tendon healing in vitro or in animals seems to be confirmed, clinical studies are currently still controversial. In addition, there is still only a limited number of randomized and controlled studies reviewing PRP for treating tendinopathy. However, it seems that PRP can be efficient to treat lateral epicondylitis, patellar tendinopathies and plantar fasciitis, even if the level of proofs remains low. Up to now there is not enough proofs concerning the use of PRP to treat rotator cuff or Achilles tendinopathies. More randomized, controlled and blinded studies remain needed. In conclusion, experimentally, PRP, through the local release of various growth factors stimulates tendon healing. This therapy could optimize the healing of pathological human tendons. PRP should be analysed to see whether it improves tendon healing in both humans and animals through other randomized controlled trials. [less ▲]

Reasons to perform study. To assess lameness in animals, semi-objective scales are used. Video is sometimes used to enable blinding of the clinician. In addition, the assessment of pain is particularly difficult in animals since they cannot report their feelings. The interpretation of the reactions of the animals can be different between observers. A method to quantify pain is the measure of mechanical nociceptive thresholds (MNT), a method called algometry. Since synovitis is often linked to swelling of periarticular tissues and to synovial fluid effusion, palpation of the joint is also a useful test. The objectives of the current study were to assess in sheep whether (1) video assessment of lameness is in agreement with real observation; (2) algometry of the knee is correlated with lameness evaluation; (3) algometry is correlated with identification of swelling by palpation. Material and methods. The population of sheep enrolled in a controlled trial at the Ovine Research Center of UNamur was used for the current study. Results. There was a moderate inter-rater agreement (value of kappa was 0,41) between the experimenter who evaluated the ewes on site and the one who watched the videos. No significant correlation was identified between lameness scores and algometry. A negative correlation (algometry reactive threshold is lower when palpation score is higher) was identified between palpation scores and MNT (P<0.05). Discussion. Video assessment can be used in research to assess lameness. The experience of the observer must be taken into account. Algometry is not entirely valid since an adaptation or learning process seems to develop in sheep. [less ▲]

Intorduction: Some clinical series have evaluated the effect of platelet-rich plasma (PRP) in the treatment of jumper’s knee. Although it is possible that a single infiltrative administration may prove to be an effective treatment for this indication, most of the existing studies evaluated the effects of 2 or 3 successive infiltrations. Purpose: The aim of this study was to evaluate whether 2 infiltrations of PRP proves more effective than a single treatment. Methods: Twenty patients suffering from chronic jumper’s knee were enrolled into the study and split into two randomized groups (1 or 2 infiltrations of PRP, respectively). The 3-month follow-up evaluation consisted of VAS, IKDC and VISA-P scores, along with algometer, isokinetic and ultrasounds evaluations. After 1 year, subjects were contacted to define their functional evolution. Results: The concentration of the PRP used for each infiltration was similar in both groups, and contained no red or white cells. Results revealed no difference in treatment efficacy between the groups. Discussion and Conclusion: The comparison between 1 or 2 infiltrations of PRP did not reveal any difference between the 2 groups at short to mid term. A second closely-timed infiltration of PRP to treat jumper’s knees is not necessary to improve the efficacy of this treatment in the short term. A second infiltration should perhaps be envisaged later, but this remains to be demonstrated. [less ▲]

Introduction : Platelet-rich plasma injections are a recent treatment for chronic tendinopathies. However, this theraeutic remains controversed in litterature. Up to now, there is no prognosis factors identified to predict a good evolution after injection of PRP. Purpose: The aims of this study were to evaluate the effect of PRP injection followed by a standardized reeducation protocol among patients suffering from different tendinopathies and to determine the good prognosis factors, if any. Methods : 51 patients suffering from different tendinopathies and refractory to conventional physiotherapy were treated with a PRP injection. Prior to the injection, a blood sample was drawn and some biological parameters (glycemia, cholesterol level, …). A pain assessment was then made using a visual analog scale (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 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. Discussion and Conclusions : A PRP injection followed by a program of eccentric rehabilitation positively affects the algo-functional scores of patients with tendinopathie who were refractory to conventional physiotherapy, whatever their initial biological parameters.

INTRODUCTION: Very strenuous exercises can be performed on an isokinetic dynamometer in order to evaluate the resistance to fatigue of different muscular groups. Good cardiac function is necessary in order to perform these very intensive exercises; otherwise an acute myocardial dysfunction could theoretically appear in predisposed patients. PURPOSE: Our study aimed to observe the cardiovascular impact (by biological point of view) of maximal intense isokinetic eccentric and concentric protocols performed by a population of sedentary young men. METHOD: Resting (T0) and post-exercise (just after (T1), 3 hours (T2) and 24 hours after the exercise (T3)) blood samples were taken in 2 populations of young sedentary men: 12 subjects (22.5±1.15 yo) for the eccentric protocol and 18 subjects (22.4±2.6 yo) for the concentric protocol. These subjects performed an intense maximal isokinetic exercise of the quadriceps muscles involving 30 knee flexions–extensions for each leg. We evaluated markers of cardiovascular risk (highly sensitive troponin T (hs-TnT), N-Terminal Brain natriuretic peptide (NT-proBNP), myoglobin (MYO)), of inflammation (highly sensitive C-reactive protein (hsCRP)), muscle damage (creatine kinase (CK)) and of oxidative stress (myeloperoxidase (MPO), lipidic peroxides (POXL), reduced (GSH) and oxidised glutathione (GSSG)). Haemodynamic parameters were measured continuously using a Portapres, and respiratory parameters were measured using a Sensormedics Vmax 29C. RESULTS: All the physiological parameters measured presented statistically significant changes. For the eccentric exercise, no significant modification in cardiac (NT-proBNP, hs-TNT) and inflammation (hsCRP) biomarkers was observed. However, a significant increase for CK (T3), MYO (T2), MPO (T1), POXL (T1), GSSG (T3) and ratio GSH/GSSG (T2-T3) was shown. For the concentric exercise, the results showed significant increases for the CK (T1-T2-T3), MYO (T1-T2), GSH/GSSG (T1). Evolutionary trends were also observed for the following biomarkers: NT-proBNP (T1-T2-T3), MPO (T2), and GSSG (T4). DISCUSSION and CONCLUSIONS: No modification in cardiac biomarkers was observed after the maximal eccentric isokinetic exercise but some variations can be observed for these biomarkers after the concentric exercise. However, these changes do not exceed the reference values in healthy subjects. We were thus able to prove that the exercise could be performed without any risk to cardiac function in young sedentary subjects. Nevertheless, a significant level of oxidative stress was induced by both exercises. [less ▲]

Introduction: Literature is scarce concerning the effectiveness of high dose radial extracorporeal shock wave therapy (ESWT). Therefore, the aim of this study was to investigate its effectiveness on pain, function and pressure pain threshold in patients with chronicplantar fasciitis (PF). Materials and Methods: Patients with a diagnosis of chronic (pain lasting for more than 3 months) uni- or bilateral PF with a history of failed conservative treatment were included. After a 6-week control period during which no treatment occurred, a 2-week treatment period followed by a three weeks of rest (cicatrization phase) was provided. The treatment period consisted of three radial ESWT sessions (2000 impulses of 10 Hz frequency per session with an energy flux density of 0,275mJ/mm2) separated by a one-weekinterval. Patient assessments (pain intensity, foot function and pressure pain threshold (PPT) at the site of maximum local tenderness disability) were conducted at baseline, after the 6-week control phase (pre-treatment) and at the end of the cicatrization phase (post-treatment). Results: Thirty patients (19 women (63.3%)) with chronic PF and a mean age of 51.9±11 years were included in the present study. No drop-out occurred throughout the study period. No changes were observed at the pre-treatment assessment session except for pain intensity which decreased slightly but significantly (P<0.05). At the post-treatment session, highly significant (P<0.001) and clinically meaningful changes occurred for pain intensity (-34%), foot function score (-60%) and PPT (+68%). Conclusions: The present study suggests that high dose radial ESWT is a feasible and effective way to quickly and significantly decrease pain and disability in most patients with chronic PF.

Objectives Patellar and calcaneal tendinopathies remain very common musculoskeletal disorders in athletes. The Victorian Institute of Sports Assessment – Patellar and – Achilles (VISA-P and VISA-A), English questionnaires developed respectively to assess the severity of patellar and calcaneal tendinopathies. The purpose of our study was to validate a French version of these questionnaires. Materials and methods The French translation and intercultural adaptation of the VISA-P and the VISA-A are made according to international recommendations. For these adaptations, 92 (VISA-P) and 116 (VISA-A) subjects were recruited and divided into 3 groups (pathological, asymptotic and sporting risk), in order to test these psychometric properties. All these subjects also had to answer to the MOS SF-36 for the validity of construct. Results The mean VISA-PF scores were 99 for the healthy people, 53 for patients with patellar tendinopathy and 86 for the athletes. The VISA-PF shows excellent reliability with an inter-class correlation coefficient of 0.99. The internal consistency was 0.9 (Cronbach's alpha). The VISA-PF shows low correlations with the divergent sub-scales of the SF-36 and moderate correlations with the convergent sub-scales of the SF-36. The mean VISA-AF scores were 99 in the healthy group, 59 in the pathological group, and 94 in the group of athletes. The VISA-AF shows excellent reliability with an inter-class correlation coefficient of 0.99. The internal consistency was 0.92 (Cronbach's alpha). The VISA-AF shows low correlations with the divergent sub-scales of the SF-36 and moderate correlations with the convergent sub-scales of the SF-36. No floor and ceiling effects were detected during the evaluation of the two questionnaires. Conclusion The French versions of the VISA-P and VISA-A questionnaires are therefore French comprehensible adaptation, reliable and adapted to French-speaking patients suffering from patellar or calcaneal tendinopathies.

Aims The aim of this study was to evaluate the impact of “VeinoPlus Sport” on amateur soccer players’ recovery after an intense physical activity (2 drills). Method We proceeded to a comparative study between two devices: “VeinoPlus Sport” and “TENS” (used as a control system) on a population of 20 players (average age 17,1±0,8). Under identical conditions each player used the two devices during two separate sessions (called group “VeinoPlus Sport” and group “TENS”). The players performed an intense effort following the YoYo test concept. Four blood samples were taken from each participant and a Myotest evaluation was performed: one before the test, one just after the first intense effort, another after a short recovery time following the first effort, and the last one right after the second intense effort. For statistical analysis, we used the Anova algorithm of the “StatPlus” system and a Scheffé test. Results With both devices, we observed a significant elevation of lactate, HCO3− ions, and myoglobin as time progressed. The analysis of other blood parameters did not show any significant evolution in the course of the testing. The “VeinoPlus Sport” group, after the session, expressed feeling lighter and more fit than usual following an intense physical activity. They did not suffer any pain, tiredness, nor diminishment of strength. The same observation was made with the “TENS” group with the exception that some players felt a bit of soreness in their thigh and calf areas. In general, all participants admitted preferring the use of recovery machines instead of natural recovery. At the same time, none expressed any preferences between either of the devices. Conclusion The main asset of this study resided in the highlighting of minor differences as no way significant between the two machines tested on the chosen population. The “TENS” shows similar results as the “VeinoPlus Sport” even if a slight preference for the latter was expressed. Both devices permitted an equal or even better performance in the second drill in comparison to the first drill. [less ▲]

Some clinical series have evaluated the effect of platelet-rich plasma (PRP) in the treatment of proximal patellar tendinopathy. Although it is possible that a single infiltrative administration may prove to be an effective treatment for this indication, most of the existing studies evaluated the effects of two or three successive infiltrations. The aim of this study was to evaluate whether two infiltrations of PRP proves more effective than a single treatment. DESIGN: Prospective, randomized and comparative study of level 2. METHODS: Twenty patients suffering from chronic proximal patellar tendinopathy were enrolled into the study and split into two randomized groups (one or two infiltrations of PRP, respectively). The 3-month follow-up evaluation consisted of VAS, IKDC and VISA-P scores, along with algometer, isokinetic and ultrasounds evaluations. After 1 year, subjects were contacted to define their functional evolution. RESULTS: The concentration of the PRP used for each infiltration was similar in both groups, and contained no red or white cells. Results revealed no difference in treatment efficacy between the groups. CONCLUSIONS: The comparison between one or two infiltrations of PRP did not reveal any difference between the two groups at short to mid term. A second closely-timed infiltration of PRP to treat proximal patellar tendinopathies is not necessary to improve the efficacy of this treatment in the short term. [less ▲]
