Leg Extension Isometrics For ACL Rehab

But if you're doing an isometric leg extension between 60 and 90° of knee flexion at up to 80% intensity in this paper, there is zero strain on the ACL. So there's no reason to not implement these isometric leg extensions as early as possible. And there's a lot of ways that you can do it. You could do it with the leg extension machine where you have the machine maxed out in weight so the person can't move it. You can use, you know, some variation of like sitting on the edge of the plinth if you're at a PT clinic and maybe like a gate belt and a towel for comfort. Um, but there there's a lot of options for doing this and I think yeah, you could do them as quickly as possible. And there's other research showing right that because this is zero straight on the ACL, this is less than walking. doing mini squats. This is less than all of the daily activities that you're doing.
