This animates a stucked sarcomere in a muscle -- it looks a bit like a stucked rusty spring. I am amazed that the Wikipedia about sarcomere mentions no word about treatments to open the stucked sarcomeres.
what kind of treatments exist to open stucked sarcomeres or a lot of stucked sarcomeres?
can a acupuncture-style treatment i.e. a small metal needle open up a closed sarcomere or a bunch of them by stimulating the blood flow?
