They have had me strapping/tapping my knee. Just over the top of the knee cap and tapping it so it pushed the knee cap over slightly. This did help a lot at work as I am on my feet all day....(work in construction) up and down ladders/scaffold etc.
But it feels like I can not fully activate the right quad, like on leg extensions at light weight I can notice that feeling/pain over the knee cap region.
Does it ache at random times? Like sitting in the car etc
Cheers
