Q

True or false

If a herniated disc leads to motor issues such as weakness, then the disc is only causing minimal pressure on the spinal cord.

A

False

Minimal pressure on the spinal cord can lead to sensory issues. However, more pressure is required to experience motor issues on top of the sensory issues.

Q

True or false

MOST (not all) patients with disc bulge have more pain and symptoms with flexion, but are relieved with extension

A

True

Because the anterior compressive forces on the disc during flexion pushes the nucleus pulposus more posteriorly, compressing the neuronal structures more , while extension relieves them

78
Q

True loss of neck passive ROM accompanied by signs of acute inflammation or muscle spasm.
