Abstract
We present a system capable of providing visual feedback for ergometer training, allowing detailed analysis and gamification. The presented solution can easily upgrade any existing ergometer device. The system consists of a set of pedals with embedded sensors, readout electronics and wireless communication modules and a tablet device for interaction with the users, which can be mounted on any ergometer, transforming it into a full analytical assessment tool with interactive training capabilities. The methods to capture the forces and moments applied to the pedal, as well as the pedal's angular position, were validated using reference sensors and high-speed video capture systems. The mean-absolute error (MAE) for load is found to be 18.82 N, 25.35 N, 0.153 Nm for Fx, Fz and Mx respectively and the MAE for the pedal angle is 13.2°. A fully gamified experience of ergometer training has been demonstrated with the presented system to enhance the rehabilitation experience with audio visual feedback, based on measured cycling parameters.

Abstract
BACKGROUND AND PURPOSE A suboptimal number of ischemic stroke patients eligible for thrombolysis actually receive it, partly because of extended inhospital delays. We developed a comprehensive program designed for emergency unit staff and evaluated its effectiveness for reducing intrahospital times and improving access to thrombolysis. METHODS We conducted a randomized stepped-wedge controlled trial in 18 emergency unit. The sequentially implemented training intervention, targeting emergency physicians and nurses, was based on specifically designed videos and interactive simulation workshops on intrahospital management optimization. The effectiveness was assessed on intrahospital times and thrombolysis proportion. During the study period, all consecutive patients with confirmed ischemic stroke and no contraindications to thrombolysis were included. RESULTS A total of 328 patients were enrolled in the control group and 363 in the intervention group. Mean age was 73.6 years. Overall thrombolysis proportion was 34.2% in the intervention group versus 25.6% in the control group (adjusted odds ratio, 1.42; 95% confidence interval, 1.01-2.01), thrombolysis proportion within 4 hours 30 minutes almost doubled (adjusted odds ratio, 1.9; 95% confidence interval, 1.32-2.73). Although imaging-to-stroke unit time was significantly decreased in the intervention group (39 versus 53 minutes; P=0.03), median door-to-imaging and door-to-needle times were not different between groups (P=0.70 and P=0.40, respectively). CONCLUSIONS An interactive and multifaceted training program targeting emergency professionals was significantly associated with an increased access to thrombolysis, especially within 4 hours and 30 minutes.
