without compromising ongoing treatments. However, fatigue is a major obstacle to adherence to a regular PA. Systematic rest is an aggravating factor of fatigue. This is why only well-designed and conducted PA programs will help a person to start intelligently activity again (i.e., programs involving evaluation, programming, individualization in their design, and adapted support and monitoring in their implementation, all framed by a qualified professional). We will develop latest recommendations for the management of fatigue by PA and innovative indications for optimal programs.

E-mail address: [email protected] (R. Souron) Objective It has been recently proposed the use of vibration as a neuromuscular rehabilitation technique. A recent study showed significant strength improvement after 14 days of local vibration training on the Achilles tendon. An improvement of the motor drive from the cortical level has been proposed to be one of the mechanisms involved. The aim of the current study was to assess the effects of an 8-week local vibration training (24 sessions of 1 h each) on: – the maximal voluntary contraction (MVC); – the cortical voluntary activation (VATMS) assessed using transcranial magnetic stimulation (TMS) technique for the tibialis anterior (TA) muscle. Material/patients and methods Forty-four healthy subjects (n = 22 for both training and control groups) participated in this study. Force measurements were performed during voluntary isometric dorsiflexion with knee and ankle angles fixed at 120 and 90◦ , respectively. During MVCs, the use of TMS allowed VATMS assessment as follow: VATMS = (1 – [SITMVC/ERT] × 100) where SITMVC is the superimposed twitch evoked during MVC, and ERT the estimated resting twitch determined by linear regression of the relation between SIT amplitude evoked when TMS was delivered at 100, 75 and 50% MVC and voluntary force. This relation was then extrapolated and the y-intercept was interpreted as the ERT amplitude. Results MVC was increased after the 8 weeks of local vibration training (+10.2 ± 11.6%, P = 0.0001). VATMS was also significantly increased (+4.9 ± 9.2%, P = 0.002). No significant variation was reported for the control group neither for MVC (P = 0.73) or VATMS (P = 0.99). Discussion–conclusion Local vibration training appears as an effective method to induce corticospinal adaptations. Thus, such a technique may have a practical relevance for preventive and/or rehabilitation intervention. Keywords Vibrations; Rehabilitation; Corticospinal adaptation

E-mail address: [email protected] (S. Mandigout) Objective The aim of this work is to compare the evaluation/measurement of the daily energy expenditure related to physical activity with the use of different actimeters currently available. Material/patients and methods Twenty-four young healthy adults voluntarily participate in this study. Energy expenditure related to the realization of daily physical activities was assessed during 24 hours with three accelerometers (Actigraph GT3X-BT, Actical and Stayhealthy RT6) and with a pedometer (ONStep Geonaute). Subjects were asked to wear the three devices simultaneously at the hip in accordance with manufacturers’ recommendations. Results Statistical analysis highlights that energy expenditure values provided by each of the four actimeters are significantly different from each other. Discussion–conclusion Overall, the results of this comparative study point out an important disparity of daily energy expenditure values provided by each of the four tested actimeters. While the recent technological development and progress in the field of new information and communication technologies and actimetry offer a real opportunity of ambulatory evaluation of physical activity and energy expenditure, further development and validation studies are still required in order to consider an utilization of these solutions in clinical routine.

Chronic pain and activity: Avoidance, pacing. . . or persistence? Franc¸ois Luthi Clinique romande de réadaptation, département de l’appareil locomoteur, Sion, Switzerland E-mail address: [email protected] Objective Activity behaviour patterns influence the development and perpetuation of musculoskeletal pain. Three major patterns have been observed in chronic pain patients: avoidance, pacing and persistence (also labelled “overdoing”, “confronting” or “endurance” pattern). Material/patients and methods Relationships between these patterns and clinical outcomes remain inconclusive. Associations between pain, disability, depressive symptoms, and poor selfefficacy have been consistently demonstrated for the avoidance model. In contrast, studies examining the two others patterns are scarce and show conflicting results. Persistence characterized by higher and more fluctuating levels of activity were also believed to be related to poor outcomes due to overuse. Nevertheless, the few studies available found that persistence may either be functional or dysfunctional depending upon association with activity avoid-
