Aim:~The aim is to identify differences in quality of rest as reflected by clinical evaluation, pulse rate, motor activity and autonomic balance between the optimized resting environment (ORE) and the standard resting environment (SR).~Method: A Randomized controlled time-series study. Randomization to either SR or ORE for each of the 9 resting periods during a three-day recording session. A period of three days will allow collection of sufficient data. This will also allow the analysis to take the random effects of time and weekday into account. Outcome measures will be differences in mean heart rate during daytime resting periods, aggregated measures of heart rate variability and proportion of resting minutes according to accelerometry.
This study investigates whether an individually designed environment can support and improve the quality of daytime resting periods in in-hospital neurorehabilitation of patients suffering severe acquired brain injury.~The effect of a individually optimized resting environment will be tested against a standard resting environment.
