Nerves and Muscle function

post #1 of 3
Thread Starter 
So I've been working with this physical therapist for a couple of weeks now. One of the first things they did was to get my Big toe flexor muscles to work. It was like my body couldn't figure out which muscles to muse to flex it. They did this by applying pressure to muscle ends (insertion points maybe?)in my toe. This week they figured out that my Transverse abdominis (spelling probably wrong) wasn't engaging properly. Again pressure points on muscle ends. Seems to make it engage better. To me this is pretty amazing stuff. Anybody familiar with these techniques? How does this stuff work?

Nord, I did not reply to this earlier, because I did not know what you were in physical therapy for. Can I assume this is in reference to the problem you had with your SI joint? Did this reult in nerve dammage to the foot?

A split second PRIOR to ANY sort of movement, the transverse abdominus muscle will activate in healthy individuals. In the case of leg movement, if it does not activate before foot strike, the SI joint will be unstable. This can cause back problems. It can also cause knee or foot problems. An unstable SI will cause a misalignment of the femur, leading to a disaterous chain of events.

A good example of people who have an underactive transverse: observe skiers poling on flat terrain. If there is too much torso movement their transverse is possibly malfunctioning, and they are prime candidates for back, knee, foot or shoulder problems.

Take a look at the kinetic chain thread: http://www.epicski.com/cgi-bin/ultim...&f=11&t=000105

Muscles, based on feedback from the nervous system create movement.

As to how your PT stimulated the transverse by stimulaing the foot, since I'm not a PT myself, I'm not sure. Maybe you should ask? [img]smile.gif[/img]

I not sure it's really nerve damage. It may be that my nervous system has "forgotten" how to activate certain muscles. I broke an ankle a while ago and had scar tissue in the area where the nerve passes through to the toe. The same toe has also been frostbite so it could have been that also. I'm seeing a Physical therapist about my knee. The therapist is working through the whole kinetic chain. Toes, ankle, knee, hip, SI, Low back and Trunk to eliminate problems.

The general theory of activating the muscle is that the muscle sends signals to the brain when manipulated in certain ways. This simulation causes the brain to send signals to the muscles re-establishing activation of the muscles.
