3 principles of stabilization of training |
|
Definition
conscious activiation and control of key muscles of trunk and pelvic girlde must be achieved before trunk stabilization can be progressed training initially in mid positoin (neutral) lessens risk of adverse stress on injured structures too much resistance on a weakened muscle can be inhibitory, causing loss of control and substitution |
