[Impingement and kinesiology]

During physical activity, especially in sport, repeated and/or exaggerated movements may lead to different impingements. Rupture, luxation, and tendon insertion injuries are seen after mobilization in the acute phase, but the goal of this paper is to analyze chronic impingements. It is possible to see the consequences of these impingements in all the musculoskeletal structures but, in relation to movement, three groups can be described. In the first, there is chronic compression and percussion between two structures; in the second there is entrapment and friction, and in the third, there is distraction. These impingements are frequent and are seen in all people, but particular movements during sport can increase their frequency.
