Video protocol – donning and doffing times
pain
Starting and preparing the RobExReha system included the activation of the system and HoloLens, the connection of the HoloLens to the robot, donning the elbow brace onto the patient’s arm and connecting it to the robot flange, weighing of the arm as well as preparation and donning of the HoloLens. This collectively took a median of 293 s (range 173–452 s). The two most time-consuming steps of the starting procedure were donning the HoloLens, which took a median of 49 s (10–151 s), and donning of the elbow brace, which took a median of 47 s (40–100 s).Termination and doffing of the RobExReha system included a pain assessment, disconnecting the brace from the robot and doffing of the brace and HoloLens. In total, this took a median of 67.5 s (29–114 s). Doffing the HoloLens took a median of 17.5 s (13–37 s). Disconnecting the brace from the robot was perceived as easy, which was reflected by the median disconnection time of 12 s (6–28 s).
