Adds ZERO lifting power to your legs. Too much "slack" in the springs, before engagement.
This brace adds virtually ZERO lifting power to your legs. I have ALS and was looking for something to prevent "kick out" of the knee. This ain't it. Even with both springs, the performance was zero. No difference. The "slack" in the design means that your knee already bends perhaps 20% before the springs engage. This is a great idea, but extremely poor performance. DO NOT BUY this thinking you are going to be able to life more. The springs are so weak, I doubt a 10 year old would even notice them. Sorry, just being honest. The springs are too weak and the "slack zone" makes these useless for people with weak knees who want support to stand.
