What causes gluteal nerve damage?

Is the superior gluteal nerve motor or sensory?
The superior gluteal nerve is a motor branch of the sacral plexus that arises from the posterior divisions of the L4, L5, and S1 anterior roots. On its way, it passes through the greater sciatic foramen accompanied by the superior gluteal artery and vein.
