“…In general, spinal pathologies such as radiculopathy [1] and degenerative spinal disease [5] may cause a delay in neural signal transfer, and this can result in a longer DRT. Although only the right leg is involved in a braking procedure, several reports demonstrated a prolonged DRT before and after surgical interventions of the left lower extremity in total hip replacement [6,8], total knee replacement [7,9,10], anterior cruciate ligament reconstruction [11,12], selective nerve root blocks [1] and lumbar disc surgery [3]. Liebensteiner et al [5] showed an influence of primary lumbar fusion on DRT in patients with chronic lumbar back pain.…”

“…Brake response time (BRT) (also referred to as driving reaction time by some authors [7-9]) is one of the most important factors responsible for driving safety [9,10]. BRT has been investigated in the context of various orthopedic treatments [6,8,9,11-13]. …”

BackgroundAlthough the numbers of total knee arthroplasty (TKA) are increasing, there is only a small number of studies investigating driving safety after TKA. The parameter 'Brake Response Time (BRT)' is one of the most important criteria for driving safety and was therefore chosen for investigation.The present study was conducted to test the hypotheses that patients with right- or left-sided TKA show a significant increase in BRT from pre-operative (pre-op, 1 day before surgery) to post-operative (post-op, 2 weeks post surgery), and a significant decrease in BRT from post-op to the follow-up investigation (FU, 8 weeks post surgery). Additionally, it was hypothesized that the BRT of patients after TKA is significantly higher than that of healthy controls.Methods31 of 70 consecutive patients (mean age 65.7 +/- 10.2 years) receiving TKA were tested for their BRT pre-op, post-op and at FU. BRT was assessed using a custom-made driving simulator. We used normative BRT data from 31 healthy controls for comparison.ResultsThere were no significant increases between pre-op and post-op BRT values for patients who had undergone left- or right-sided TKA. Even the proportion of patients above a BRT threshold of 700 ms was not significantly increased postop. Controls had a BRT which was significantly better than the BRT of patients with right- or left-sided TKA at all three time points.ConclusionThe present study showed a small and insignificant postoperative increase in the BRT of patients who had undergone right- or left-sided TKA. Therefore, we believe it is not justified to impair the patient's quality of social and occupational life post-surgery by imposing restrictions on driving motor vehicles beyond an interval of two weeks after surgery.

“…The effect of total hip replacement on reaction times suggests a delay of eight weeks, 4 and a similar period is recommended following total knee replacement. 5 In order for reaction times to recover following anterior cruciate ligament reconstruction a period of six weeks is recommended, 6,7 and following knee arthroscopy the period is one week, 8 which is similar to that after inguinal hernia surgery. 9 However, there are very few studies of patients with right lower-limb immobilisation that provide empirical data upon which to give evidence-based advice.…”

The purpose of this study was to investigate the effects of right leg restriction at the knee, ankle or both, on a driver's braking times. Previous studies have not investigated the effects of knee restriction on braking performance. A total of 23 healthy drivers performed a series of emergency braking tests in a driving simulator in either an above-knee plaster cast, a below-knee cast, or in a knee brace with an increasing range of restriction. The study showed that total braking reaction time was significantly longer when wearing an above-knee plaster cast, a below-knee plaster cast or a knee brace fixed at 0°, compared with braking normally (p < 0.001). Increases in the time taken to move the foot from the accelerator to the brake accounted for some of the increase in the total braking reaction time. Unexpectedly, thinking time also increased with the level of restriction (p < 0.001). The increase in braking time with an above-knee plaster cast in this study would increase the stopping distance at 30 miles per hour by almost 3 m. These results suggest that all patients wearing any lower-limb plaster cast or knee brace are significantly impaired in their ability to perform an emergency stop. We suggest changes to the legislation to prevent patients from driving with lower-limb plaster casts or knee braces.
