Trapezius jerk is an example of deep tendon reflex
The finger is placed over the trapezius muscle parallel to the spine
Then strike the index linger placed on the trapezius muscle
Slight elevation the shoulder can be seen.There is exaggerated reflex in pyramidal tract lesion
Trapezius Jerk Innervation
Trapezius jerk is supplied by spinal segment C3,C4
Abnormality in Trapezius jerk
It is exaggerated in corlicospinal tract lesion above C3
Commonly seen in patients with cervical spondylosis
Examination of upper-extremity deep tendon reflex may be helpful in planning the appropriate levels for surgical decompression in patients with multilevel spondylosis and myelopathy
