Electromyographic (EMG) research on individuals with low back pain suggests the rectus abdominis exhibits which of the following traits?
A. Stronger in trunk flexion than extension, decreased recruitment during stair climbing, A and an inability to differentiate between transverse abdominis and rectus abdominis activation during the abdominal drawing-in maneuver (ADIM)
B. Weaker in trunk flexion than extension, increased recruitment during stair climbing, and can easily differentiate and recruit the rectus abdominis during the abdominal drawing-in maneuver (ADIM)
C. Stronger in trunk flexion than extension, decreased recruitment during stair climbing, and can easily differentiate and recruit the rectus abdominis during the abdominal drawing-in maneuver (ADIM)
