Despite the importance to patients of driving, no well-established guideline exists to help either the patient or the physician determine when it is safe for the patient to return to driving. Previous studies have recommended 6 weeks postoperatively before patients can return to driving safely. Several scientific studies have found the nationally recommended safe brake time standard to be 1.25 sec (1,250 msec), looking at brake reaction time (BRT) in all types of patients, surgical and nonsurgical.
This is a prospective study assessing BRT after individuals are placed in various forms of immobilization (controlled action motion [CAM] boot, surgical shoe). The study also tested whether BRT is different when using the left foot to brake, with immobilization of the right foot.
All 29 male and 71 female participants in this study (mean age, 35.49 years) were capable of driving and were not currently being treated for any foot or ankle conditions. No differences were found regarding age, sex, and use of assistive devices. The mean BRT while wearing a CAM boot was 713 msec, while using the left foot to brake (CAM boot on the right foot) was 593.86 msec, and while wearing a surgical shoe was 626.32 msec.
Although most of the study participants were below the nationally recommended safe brake time standard, it was found that not all of the participants fell within these parameters.
尽管驾驶对患者很重要，但目前尚无完善的指南来帮助患者或医生确定患者何时可以安全恢复驾驶。先前的研究建议术后6周患者才能安全恢复驾驶。几项科学研究发现，全国推荐的安全制动时间标准为1.25秒（1250毫秒），该标准适用于所有类型的患者，包括接受手术和未接受手术的患者，观察其制动反应时间（BRT）。
这是一项前瞻性研究，评估个体在接受各种形式的固定（可控动作运动[CAM]靴、手术鞋）后的BRT。该研究还测试了右脚固定时用左脚制动时BRT是否不同。
本研究的所有29名男性和71名女性参与者（平均年龄35.49岁）均能够驾驶，且目前未因任何足部或踝部疾病接受治疗。在年龄、性别和辅助设备使用方面未发现差异。穿着CAM靴时的平均BRT为713毫秒，用左脚制动（右脚穿CAM靴）时为593.86毫秒，穿着手术鞋时为626.32毫秒。
尽管大多数研究参与者低于全国推荐的安全制动时间标准，但发现并非所有参与者都在这些参数范围内。
