Abstract
We conducted a prospective study in 46 consecutive patients mean age 489 years to determine driving reaction time DRT before and after surgery in patients with lumbar disc herniation Of the patients 23 had leftside radiculopathy and 23 rightside radiculopathy Driving reaction time as well as back and leg pain were evaluated preoperatively on the day of discharge from hospital and at the 5week followup examination FU 31 healthy subjects were tested as controlsSignificant improvement in DRT was seen for both patient samples p 005 For patients with a rightside radiculopathy preoperative DRT was 664 ms median IQR 241 which was reduced to 605 ms median IQR 189 immediately postoperatively and to 593 ms median IQR 115 at FU For patients with a leftside radiculopathy DRT was 675 ms median IQR 247 preoperatively 638 ms median IQR 242 postoperatively and 619 ms median IQR 162 at FU Pain was moderately correlated to DRT Control subjects had a driving reaction time of 487 median IQR 116 which differed significantly from patients at all three testing times p 0001Our data indicate a positive effect of the surgery on driving ability Therefore we would suggest that for both patient samples it is safe to continue driving after hospital discharge However patients have to be informed about increased DRT caused by radiculopathy already before surgery
