Introduction: The Anterior Knee Pain Scale (AKPS) is a questionnaire used to examine the subjective symptoms, such as the functional limitations and the anterior knee pain. First developed in English, this questionnaire has since been translated and validated into several languages. The aims of the study were to translate and cross-culturally adapt the AKPS into French and to evaluate the reliability and validity of this translated version of the questionnaire. Methods: The translation part was articulated in six stages, according to international guidelines: (i) two initial translations from english to french; (ii) synthesis of the two translations; (iii) backward translations into the original language; (iv) expert committee to compare the backward translations with the original questionnaire (v) pre-final version testing and (VI) expert committee appraisal. To validate the French AKPS questionnaire, we assessed its validity, reliability and floor/ceiling effects. To do this, volunteer patients from Belgium and France, with patellofemoral pain syndrome were asked to answer the french version of the AKPS questionnaire at baseline and after 7 days, as well as the generic SF-36 questionnaire. Results: The AKPS questionnaire was translated without any major difficulties. A total of 101 subjects aged 34.49 ± 11.38 years on average were included in this study. Among them, 58.4% were women. Results indicated an excellent test-retest reliability (intraclass coefficient correlation of 0.97, 95% CI 0.96 - 0.98), a high internal consistency (Cronbach’s alpha of 0.87), a consistent construct validity (high correlations with the SF-36 questionnaire were found with domains related to physical function (r = 0.80), physical role (r = 0.70), pain (r = 0.64)) and low or moderate correlations with domains related to mental health (r = 0.26), vitality (r = 0.32), social function (r = 0.41)). Moreover, no floor/ceiling has been found. Conclusion: A valid AKPS french questionnaire is now available and can be used with confidence to better assess the disease burden associated with femoropatellar syndrom. It was successfully cross-culturally adapted into French. [less ▲]

Introduction: Patellar Tendinopathies (PT) represent a very frequent disorder which incidence can reach 30-50% among jumping sports. This trouble is often rebel to classical treatment. Objective: To compare the efficacy of a single injection of RPR to a double infiltration of HA at one week interval. Patients/Methods: Thirty-three patients suffering from PT were enrolled into the study and split into two randomized groups . Eighteen patients (Group 1) have received one PRP injection and the other fifteen subjects (Group 2) received two HA infiltrations. Pain and functionality of the knee were evaluated before injection (T0), 6 weeks (T2) and 3 months (T3) after injections: pain with VAS and pressure algometer, algofunctional scores with IKDC and VISA-P questionnaires, ultrasound, isokinetic evaluation (quadriceps contractions : concentric 60°/sec (C60), concentric 240°/sec (C240), excentric 30°/sec (E30) and VAS during testing). Results: At baseline, difference existed only between groups for algometer, tendon thickness and axial hypoechoic area. In both groups, VAS, algometer, IKCD, VISA-P, VAS for isokinetic testing C60, C240 and E30 were significantly improved at T2 and T3 compared to T0. Comparison between the 2 groups showed no difference excepted for algometer, tendon thickness (T2, T3) and axial hypoechoic area (T2). Discussion and conclusions: There existed a similar improvement of the symptoms in both groups. PRP has already shown its efficacy in PT. HA should probably be a new therapeutic opportunity in this indication. Nevertheless, it should better, for further studies, to include a more homogeneous population and a longer follow-up period of time. [less ▲]

Introduction : Le syndrome fémoro-patellaire est l'un des problèmes du genou les plus fréquemment rencontrés. Il se caractérise par une douleur antérieure du genou dans les activités mettant en charge l'articulation fémoro-patellaire. Le Kujala Anterior Knee Pain Scale (Kujala AKPS) est un questionnaire utilisé pour évaluer les symptômes subjectifs, telles que les limitations fonctionnelles et la douleur antérieure du genou. Le questionnaire a déjà été traduit et validé en turc, en portugais brésilien, en persan, en chinois, et en néerlandais. Le but de cette étude est de traduire ce questionnaire en français afin d'en évaluer sa fiabilité et sa validité. Matériel et méthode : La traduction et l’adaptation interculturelle du questionnaire ont été réalisées selon les recommandations internationales comprenant 6 étapes : traduction initiale, synthèse des traductions, traduction de retour vers la langue d’origine, comité d'experts, test de la version pré-finale et approbation du comité d'experts. Une fois la version française obtenue, les participants (n=101) ont rempli 2 fois le Kujula AKPS à un intervalle de 7 jours, et le Short Form Health Survey (SF-36) afin d'en évaluer les propriétés psychométriques (la cohérence interne, la fidélité test-retest et la validité de construit). Résultats : Le Kujula AKPS montre une fidélité test-retest élevée pour le score total (ICC 0,97). La traduction française possède une cohérence interne élevée (0,87). Le Kujula AKPS 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 (MH, SF et VT). Il n’y a pas d’effet plancher et plafond. Conclusion : La version française du questionnaire Kujula AKPS étant facilement compréhensible, elle semble avoir une bonne adaptation interculturelle. Cette étude a démontré que le Kujula AKPSF est fiable et valide pour les patients francophones souffrant d'un syndrome rotulien. [less ▲]

BACKGROUNDS: The aim of this study was to assess the relationship between the level of ambulatory physical activity, measured by physical activity tracker, and the clinical components of physical frailty, among nursing home residents. METHODS: We proceeded in 3 steps: (1) Validation of the physical activity tracker (i.e. the Pebble): 24 volunteer adults walked on a treadmill. The number of steps recorded by the Pebble worn by the subjects was compared with the number of steps counted by the investigators, by means of the Intra-class correlation coefficients (ICC). (2) Measurement of ambulatory physical activity, using the Pebble trackers, over a 7-day period. (3) Relationship between the results obtained with the Pebble trackers (step 2) and subjects' clinical characteristics, linked to physical frailty. RESULTS: ICC data, showed that the reliability of the Pebble was better when it was worn at the foot level (ICC ranged from 0.60 to 0.93 depending on the tested speed). Gait speed is also an important determinant of the reliability, which is better for low gait speed. On average, the 27 nursing home residents included in the second step of this study walked 1678.4+/-1621 (median=1300) steps per day. Most physical components of frailty measured in this study were significantly different between subjects who walked less than 1300 steps per day and those who were more active. CONCLUSION: This study showed that nursing home residents have a poor ambulatory physical activity, assessed using a physical activity tracker, which is associated with poorer physical performances and higher disability.

Background A specific self-administrated health-related quality of life questionnaire for sarcopenia, the Sarcopenia and Quality Of Life (SarQoL®), has been recently developed. This questionnaire is composed of 55 items translated into 22 questions and organized into seven domains of quality of life. The objective of the present work is to evaluate the psychometric properties (discriminative power, validity, reliability, floor and ceiling effects) of the SarQoL® questionnaire. Methods Sarcopenic subjects were recruited in an outpatient clinic in Liège, Belgium and were diagnosed according to the algorithm developed by the European Working Group on Sarcopenia in Older People. We compared the score of the SarQoL® between sarcopenic and non-sarcopenic subjects using a logistic regression after adjustment for potential confounding variables. Internal consistency reliability was determined using Cronbach’s alpha coefficient; construct validity was assessed using convergent and divergent validities. Test–retest reliability was verified after a two-week interval using the intra-class correlation coefficient (ICC). At last, floor and ceiling effects were also tested. Results A total of 296 subjects with a median age of 73.3 (68.9–78.6) years were recruited for this study. Among them, 43 were diagnosed sarcopenic. After adjustment for potential confounding factors, the total score and the scores of the different dimensions of the SarQoL® questionnaire were significantly lower for sarcopenic than for non-sarcopenic subjects (54.7 (45.9– 66.3) for sarcopenic vs. 67.8 (57.3 – 79.0) for non sarcopenic, OR 0.93 (95%CI 0.90–0.96)). Regarding internal consistency, the Cronbach’s alpha coefficient was 0.87. The SarQoL® questionnaire data showed good correlation with some domains of the Short-Form 36 (SF-36) and the EuroQoL 5-dimension (EQ-5D) questionnaires and with the mobility test. An excellent agreement between the test and the retest was found with an ICC of 0.91 (95% CI 0.82–0.95). At last, neither floor nor ceiling effects were detected. Conclusions The SarQoL® questionnaire is valid, consistent, and reliable and can therefore be recommended for clinical and research purposes. However, its sensitivity to change needs to be assessed in future longitudinal studies. [less ▲]

BACKGROUND: The objective of this study was to assess the reliability of a hand-held dynamometer for isometric strength measurements among nursing home residents. METHODS: The isometric muscle strength of nursing home residents was assessed for eight different muscle groups, using a hand-held dynamometer, the MicroFET2 device. Strength measurements were performed at baseline and after 4 days by the same operator and after 8 days by a second operator. Intraclass coefficients (ICC) were computed to assess the relative reliability, whereas the minimal detectable change (MDC%) was calculated to assess the absolute reliability of the test-retest of the MicroFET2 used by one single operator or by two different ones. RESULTS: Thirty nursing home residents (75.0 +/- 11.2 years, 50% of women) were enrolled in this study. ICC of the test-retest with one single operator ranged from 0.60 (0.37-0.83) for the ankle extensors to 0.85 (0.74-0.95) for the elbow flexors. When considering the test-retest with two different operators, the ICC values ranged from 0.62 (0.41-0.84) for the ankle extensors to 0.87 (0.79-0.96) for the elbow extensors. For the absolute reliability, MDC% varies from 27.64 (elbow flexors) to 81.97 (ankle extensors) when performed in intra-observer. In interobserver condition, MDC%, respectively, varies from 24.38 (elbow extensors) 67.59 (ankle extensors). CONCLUSION: Using standardized protocol and standardized instructions to patients, a high relative and moderate absolute reliability was observed for all but ankle muscle groups, making this hand-held dynamometer a potential tool for research in the elderly population.

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 ▲]

AIM OF THE STUDY: The lack of traceability and monitoring of blood donors and transfused patients constitute a barrier to the most basic rules of haemovigilance and overall good transfusion practices. This study draws up an inventory of knowledge, attitudes and clinical practice of blood prescribers in Niamey. MATERIALS AND METHODS: A questionnaire was administered to 180 prescribers of blood products in Niamey in 2011. Questions were related to basic informations on blood transfusion and clinical use of blood. Analyses were performed using SAS 9.3 version. RESULTS: The sample consisted of 180 respondents from several professional categories: 51 physicians (28.33%), 10 medical students (5.56%), 84 nurses (46.67%), 15 anaesthesiologist assistant (8.33%) and 20 midwives (11.11%). Among these, 22.2% received training in blood transfusion safety. Half of the respondents (50.8%) got between 50 and 75% of correct answers, 45.8% got less than 50% correct while 3.35% scored more than 75% correct answers. The overall quality of responses was higher among physicians compared to other prescribers (P<0.0001); among respondents who received training in transfusion safety (P<0.0001); and among males (P=0.0306). For some items, subjects with more experience scored the best. CONCLUSION: The level of knowledge is still inadequate. More training in transfusion practices is necessary for prescribers of blood products. Accompanying measures to improve transfusion practice must be considered or strengthened through assessments, knowledge update/upgrade (regular, ongoing training) and establishment of active and motivated hospital transfusion committees.

Objectives: Predicting the post-dilution hematocrit is an important tool to avoid preventable anemia or unnecessary transfusion. Simplified empirical formulas currently used for such a prediction may lead to large errors. We aimed to improve the accuracy of these formulas by a better estimation of the dilution volume and the patient circulatory blood volume. Methods: We compared the estimation accuracy of two formulas, using fixed (formula A) versus estimated (formula D) dilution volume and patient circulatory blood volume for 100 cardiac interventions. The difference between predicted and measured HctT1 was considered as “good” if less than 0.5%, “moderate” between 0.5 and 2% and “poor” if higher than 2%. The influence of the body mass index (BMI) on patient blood volume estimation was explored by categorized groups’ comparison. Results: The mean difference between predicted and measured HctT1 differed significantly between formulas A and D. Formula A didn’t differ from HctT1 (p=0.19, IC95% [-0.89-0.18]), but a significant and higher underestimation was observed in the BMI⩽25 group compared to the other BMI groups (p<0.001). Formula D overestimated HctT1 (p<0.001, IC95% [1.01-1.93]) without a difference between the BMI groups. No difference was observed in their overall proportions of good (11 vs 10%), moderate (44 vs 46%) and poor predictions (47 vs 44%) (p=0.117). Conclusions: Formulas used for post-dilution hematocrit prediction lead to major estimation errors and a risk of inadequate transfusion practices. Estimations performed by experienced clinicians could not minimize these biases in all clinical cases as significant errors remain, with potential clinical impact. No estimation formula should be used as a hard tool for transfusing patients, but rather as a guide to predicting the probability of transfusion requirement. [less ▲]
