They are, 1. Now I have used the terms of restraint, knowingly, unlawfully and serious bodily injury. The word restraint means confinement, abridgement or limitation.
Restraint involves hinderance, confinement or restriction of liberty.
You will note that I have used the term unlawful. The term serious bodily injury means bodily injury which creates a substantial risk of death or which causes serious permanent disfigurement or protracted loss or impairment of the functions of any bodily member or organ. If, however, after a consideration of all of the evidence you find that the State has failed to prove each and every element of the offense beyond a reasonable doubt, your verdict must be not guilty.
