PowerCranks as an ACL rehabilitation tool

When it comes to rehabilitation of ACL problems when and how one can use the various lower extremity muscles will depend upon your specific problem or on the type of surgical repair you have had. Rehab of an injured ACL, that does not require surgery is substantially different than the issues involved in rahabilitation following surgery. If you are trying to rehab from a "simple" injury and trying to prevent further damage the PowerCranks can be used without much worry with the goal being to get the muscles around the knee being balanced and strong. The toughest one to train here is, usually, the hamstrings. PowerCranks do a particularly good job at training this muscle.

If you are post-surgical repair, while the general goal is to strengthen and balance all of the muscles around the knee (something the PowerCranks do extremely well) sometimes, depending upon the specifics of the surgical proceedure, exercising the hamstring muscles must be delayed until enough healing has occurred. Since using PowerCranks force the use of the hamstrings be sure to coordinate PowerCranks use with your doctor/therapist. Once it is ok to use the hamstrings, PowerCranks can, again, be particularly effective at helping you to achieve your goal more quickly and more easily.

The nice thing about rehabilitation using PowerCranks is one knows when the legs are again equal and balanced. If an athlete, when the rehab is over usually little has been lost in running ability and many report actually being able to run faster than before their injury.

Check out the video in which many users discuss what using the cranks were able to do for them or their clients following injury.

" I think they're great for recruiting hamstrings in my post-op ACL patients, and I like using them during bike fittings to illustrate proper spinning."

"I began using Powercranks in 2001 as a rehab tool and after trying to resolve an Illiacus/Psoas strain that just would not heal and strengthen with regular rehab methods. I noticed significant improvements in pedaling mechanics, strength and power. I am convinced that Powercranks work and am glad I can recommend them to clients."
Coach Rob Swan
