examples of traumatic brain injury
fractures, bleeds, contusion
With the client placed
supine, passive flexion of
the neck causes
involuntary flexion of the
knee and hips.
Brudzinski’s sign
Damage to the spinal cord causes permanent changes in strength, sensation, and
other body functions below the site of the injury

With the client placed supine
and the hip flexed, the knee
cannot be completely
extended due to pain.
