Abstract:
This retrospective study summarizes the range of knee extension forces associated with the manual muscle test grade of 5. The range of the forces (>560 Newtons) was large and encompassing of more than 86% of measurable forces. These findings help to explain the insensitivity of manual muscle testing and why it has such a profound ceiling effect.
