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 ▲]

Purpose. Firstly, to examine whether heart rate (HR) can be predicted based on the Borg-scale for perceived exertion in patients with chronic low back pain (CLBP) and secondly, to assess changes in HR, Borg-scores and workload to study the relevance of a stepwise increase of workload based on the Borg-score and HR. Methods. Ninety-nine patients with CLBP and a mean disability-score (Roland Morris Disability Questionnaire) of 13.8 (SD = 3.7) participated in a 10-week aerobic training programme (20 min, 3 times/week). HR, ratings of perceived exertion (RPE), and workload were monitored. Prior to treatment, patients completed questionnaires on pain, disability, and several psychological factors (catastrophizing, kinesiophobia, and depression). Results. The original Borg-equation (i.e. 'HR = Borg x 10') appears accurate in predicting HR on a group-level. Pain-related and psychological factors were not significantly related to the accuracy of the Borg equation. Whereas mean workload increased significantly (from 93.8 (SD = 29.9) to 129.5 W (SD = 39.7), p < 0.001) throughout the training programme, HR increased only slightly (from 130.2 (SD = 13.5) to 139.2 (SD = 13.9) bpm; p < 0.001) and Borg-scores remained stable (from 13.2 (SD = 1.9) to 13.3 (SD = 1.8); p = 0.48). Conclusions. The capability of the Borg-scale to accurately predict HR appears moderate. However combined with measuring HR, it results in a relevant and efficient method for training CLBP patients in clinical practice. [less ▲]
