Please give me examples of how muscles in the upper extremity can be “rebalanced” by orthopedic surgery?
Two common problems in cerebral palsy are muscles over-working and muscles under-working. Over working would include increased tone or spasticity. Spastic or high tone muscles can be weakened by surgically sectioning (cut) some of the fibers so they cannot pull as strongly. Under working would include flaccidity, weakness or low tone. Some muscles under work so much that they do not fire at all. Finding a less needed muscle that is working well and moving a part of that working muscle to the weak area can help important muscles that are weak.
