Relevance: LBP is common among tennis players. More than one third of professional tennis players reported LBP as reason for missing at least one tournament. As impaired lumbar motor functions have been associated with LBP, it appears particularly relevant to assess lumbopelvic movement control in tennis players. Methods: Twenty amateur tennis players (male, 22.9 ± 3.0 years) were included. Subjects were pooled into two groups: 10 players with chronic LBP (mean pain duration: 3.1 ± 2.6 years, pain severity score: 3.5/10 on a pain visual analogue scale) and 10 players without LBP. The Bent Knee Fall Out (BKFO) test was used to assess the players’ ability to control movement of lumbopelvic region. BKFO was performed in supine position and monitored by means of two pressure biofeedback units inflated to 40 mmHg and positioned under the lumbar spine of the participant. The reliability of this test has been previously assessed. Players were instructed to make an active abduction-external rotation movement of the hip (45°) without concomitant lumbopelvic movement of the pelvis and low back. Pressure modification (mmHg) was recorded, each side was assessed. Results: Tennis players with LBP had a worse lumbopelvic movement control than players without LBP both for dominant (9.0 mm Hg vs 3.4 mmHg, P<0.05) as well for the non-dominant side (9.1 mmHg vs 4.6 mmHg, P<0.05). Conclusions: Tennis players with LBP experience similar alterations of motor control as those observed in sedentary people with LBP. However, it remains unclear if these alterations are the cause of the consequence of chronic LBP. Implications: Further prospective studies should assess the cause or effect relationship and should determine whether motor control exercises are effective in tennis players with chronic LBP.

Objective: The purpose of this study is to assess the relevance of a technological innovation (Mi-Scan function, Compex company) offered by the range of rehabilitative and/ or sport oriented stimulators. This analysis examines the effectiveness to induce muscle contraction and the reproductibility of this function. Method: A comparison of electrically evoked torques of the quadriceps was performed with and without the aid of this function, both at submaximal and maximal stimulation intensity. Moreover, this function was studied several times under identical conditions (reproducibility study). Results: No superior efficacy has been found when using a system including the "Mi" function over a system that did not use this feature. Additionally, our results have highlighted a poor reproducibility of measurements obtained by the "Mi"sensor. Discussion: Important doubts must be made concerning the validity and reliability of this tool. [less ▲]
