from the Mexican government:This is very late. However, when I was studying to find words for grasp in terms of IEP, occupational therapy. I see they use the word presa. At first I thought it was that the sight translated with google translate or something was incorrect. However, I seen seen it in more than one location. "Presa" meaning a type of grasp (agarre o pinza). Tal vez jale es de pull. If so, then it could be the skill of grasping when pulling.
