Predictability of the Ability to Perform an Emergency Stop After Surgery for Inguinal Hernia

December 28, 2020 updated by: University Hospital Tuebingen
Several studies exist on patient performance in drive simulators especially around and after surgery. Recommendations concerning the ability to drive after inguinal hernia are scarce and so far do not offer conclusive results. Aim of the study is to analyse reaction time and foot transfer time (together brake response time) and brake force in a brake simulator before and after scheduled inguinal hernia surgery (Liechtenstein procedure).

  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Braking after inguinal hernia surgery
Cohort testing of driving performance in a brake simulator in patients before and after scheduled inguinal hernia surgery
Other: Braking performance in a brake simulator
Braking performance is tested in a real middle size car cabin to simulate ergonomic conditions of driving a car. This testing cabin has been equipped with customised equipment to allow measurement of reaction time, foot transfer time, brake response time and brake force.
