Question

Which muscles are typically overactive in the lower crossed syndrome that was described by Prof. Janda?

A) Gluteus maximus and hamstrings
B) Rectus abdominis and hip flexors
C) Erector spinae and quadratus lumborum
D) Rhomboids and serratus anterior

Answer 1

The erector spinae and quadratus lumborum muscles are typically overactive in the lower crossed syndrome described by Prof. Janda.

Step-by-step explanation:

The muscles typically overactive in the lower crossed syndrome, as described by Professor Janda, are the erector spinae and the quadratus lumborum. This condition is characterized by an anterior tilt of the pelvis, an increased curvature of the lumbar spine, and tightness in the aforementioned muscles along with the hip flexors. Conversely, the abdominal muscles and gluteus maximus tend to be underactive and weakened in individuals with lower crossed syndrome.
