..Normal values for rotation in flexion or extension cannot be established until the source of the device-dependent difference is identified...

..Consideration of the severity of concomitant LBP in LDH may assist in establishing realistic patient expectations before the surgery...

..The whiplash patients appeared either unable or unwilling to drive the cervical spine into this region of high muscle activity, possibly because they were restricted by existing pain or fear of pain...

..We examined whether the outcome of surgery for LDS varied depending on the predominant baseline symptom and the treatment administered [decompression with fusion (D&F) or decompression alone (D)]...
