Cet article évalue l'adaptabilité inter-pays d'une échelle de mesure de l'innovativité des consommateurs pouvant s'appliquer à divers domaines spécifiques de la consommation (Goldsmith et Hofacker, 1991). Cette échelle a été développée, testée et validée aux Etats-Unis uniquement. L'adaptabilité de l'instrument à d'autres contextes est évaluée dans le domaine spécifique du cinéma, à travers l'étude de ses propriétés psychométriques dans trois pays (Canada, France et Israël). Les implications théoriques, méthodologiques et managériales de cette évaluation sont discutées.

The aim of this study was to assess the effects in humans of early (2 weeks) and delayed (6 weeks) isokinetic strength training in the recovery of muscle strength following an arthroscopic partial meniscectomy. The peak torque developed in the quadriceps and hamstrings and the torque developed at a knee angle of 1.05 rad were evaluated in 16 subjects, pre-operatively (pre-op), and 2, 6, and 10 weeks post-operatively (post-op), on an isokinetic device at four different velocities (1.05, 2.09, 3.14, and 4.19 rad · s-1). The fatigue characteristics of the muscles were evaluated by having the subject perform 15 maximal contractions at 3.14 rad · s-1. Training was done on the same device (three times a week for 1–2 months), beginning either 2 or 6 weeks post-op. A repeated measures analysis of variance demonstrated a time effect but no differences between groups and no interactions. Torques developed by the knee flexors and extensors were significantly smaller 2 weeks post-op than pre-op, at all velocities tested. Torques developed in the quadriceps recovered to their pre-op values by 6 weeks, and further gained significantly in strength from 6 to 10 weeks. Quadriceps torques remained weaker than the contralateral side at 10 weeks. Hamstrings torques were either higher or similar to pre-op values by 6 weeks, and demonstrated increases from 6 to 10 weeks post-op at 1.05 and 4.19 rad · s-1 only. Total work and average power developed by the quadriceps and hamstrings during the fatigue protocol changed with time in a similar manner to torque. However, contrary to quadriceps torque, these indices of fatigue were fully recovery by week 10. In conclusion, training in the early stages following arthroscopic meniscectomy does not appear to improve the recovery of strength and the importance of timing of the training stimulus is suggested. Moreover, the results emphasize the need to include a control group when investigating the role of exercise training in the recovery of muscle function.
