“…Furthermore, the reaction time results were in agreement with results present in existing literature. 7,29-33 These findings indicate that the in-house simulator produces data that are reliable and accurate.…”

Brake reaction time is a key component to studying driving performance and evaluating fitness to drive. Although commercial simulators can measure brake reaction time, their cost remains a major barrier to clinical access. Therefore, we developed open-source software written in C-sharp (C#) for measuring driving related reaction times, which includes a subject-controlled vehicle with straight-line dynamics and several testing scenarios. The software measures both simple and cognitive load based reaction times and can use any human interface device compliant steering wheel and pedals. Measures from the software were validated against a commercial simulator and tested for reproducibility. Further, experiments were performed using hand controls in both able-bodied and spinal cord injured patients to determine clinical feasibility for disabled populations. The software demonstrated high validity when measuring brake reaction times, showed excellent test-retest reliability, and was sensitive enough to determine significant brake reaction time differences between able-bodied and spinal cord injured subjects. These results indicate that the proposed simulator is a simple and feasible low-cost solution to perform brake reaction time tests and evaluate fitness to drive.

“…Brake response time is the amount of time elapsed between the appearance of a stimulus and when contact was made with a brake pedal. Total brake time was reported in six articles [13,26,28,30,48,60]. Total brake time is the amount of time elapsed between the appearance of a stimulus and when a brake pedal is fully depressed.…”

“…Total brake time is the amount of time elapsed between the appearance of a stimulus and when a brake pedal is fully depressed. Brake force was reported in four articles [30,39,60,64]. Upper extremity immobilization studies used driving abilities score, simulators, and standardized tracks [6,7,20,21].…”

“…Data showed that a step test was the best predictor of safety when correlated with total brake time after TKA [28]. Patients with THAs had normal brake response times, total brake times, and brake forces 2 to 8 weeks after right-sided procedures [15,23,30,39,53] and 1 to 8 weeks after left-sided procedures [15,30,39]. Driving measures such as brake response time, total brake time, and brake force were significantly impaired when a driver wore a right lower-extremity hard cast, aerated orthosis, controlled ankle-motion cast, short leg cast, above-or belowknee plaster cast, or ROM-restricting brace [10,48,60,63].…”

Background Patients often ask their doctors when they can safely return to driving after orthopaedic injuries and procedures, but the data regarding this topic are diverse and sometimes conflicting. Some studies provide observer-reported outcome measures, such as brake response time or simulators, to estimate when patients can safely resume driving after surgery, and patient survey data describing when patients report a return to driving, but they do not all agree. We performed a systematic review and quality appraisal for available data regarding when patients are safe to resume driving after common orthopaedic surgeries and injuries affecting the ability to drive.

“…For the specific experimental set-up used in this study, the reference BRT limit in healthy subjects was set at 600 ms (18,19); a value that allows various parameters that may affect BRT to be tested under highly controlled and reproducible conditions. Various studies have investigated the effect of surgical procedures.…”

Background: Fitness to drive a car has been investigated increasingly over recent years. However, most research has focussed on perioperative driving performance, and few data are available on how orthoses influence the ability to perform an emergency stop. This study investigated the effect of 4 common ankle braces (Kallassy ® , CaligaLoc ® , Air-Stirrup ® , ASO ® ) on reaction time, foot transfer time (together: brake response time) and brake force. The hypothesis was that wearing these braces on the right ankle impairs braking performance, specifically by increasing foot transfer time, but also by altering brake force. Methods: A car cabin was set up with measurement equipment to register reaction time, foot transfer time, brake response time and brake force under realistic spatial constraints. A crossover repeated measures design was used to test 30 healthy volunteers with and without each of the braces. Results: All 4 braces resulted in statistically significantly increased foot transfer time (p < 0.001), compared with measurements without a brace. Reaction time with a brace was significantly prolonged, with the exception of the Kallasy ® . Brake force was not statistically significantly impaired. Conclusion: This study demonstrates that ankle braces lead to impaired braking performance. Depending on the type of brace, a stopping distance increase of more than 1 m at 100 km/h can be expected.
