1. Neck rigidity

When the nerves that control the neck muscles are stimulated, the neck muscles will produce spasmodic contraction accompanied by pain, resulting in neck stiffness and limited movement.

2. Kerning's sign is

also known as Klinefelter's sign, which is characterized by traction of the sciatic nerve and pain during hip flexion experiments after stimulation of the lumbosacral nerve roots.
