They report that the highest muscle activity was displayed in the frontal plane at 60 degrees of shoulder abduction (90.5 %), while overall muscle activity tended to be greater at
all planes of motion at 60 degrees.
Further, muscle activity tended to be similar between
planes of motion at the same shoulder elevation.

This kind

plane of motion, the rotator cuff — which is supposedly responsible for directing rotational movements
at the shoulder — never gets activated.
Keuchle et al. (2000) also reported that the deltoid moment arms were all close to zero in all

at maximal external rotation all three deltoid muscles show some positive moment arm lengths.
