User Requirements of the Neurorehabilitation Ecosystem for Sustained Therapy (NEST): an Integrated Home-based Rehabilitation Tool

After stroke, patients often experience a reduced arm-function. This function can partly be regained during a long and intensive rehabilitation. However, due to the ageing population and the increasing stroke cases, there is not enough time and money for this long and intensive rehabilitation in a rehabilitation center. Home-based rehabilitation could offer a solution to this problem. Currently, a new home-based rehabilitation system is being developed, named the Neurorehabilitation Ecosystem for Sustained Treatment (NEST). This system consists of three different components: an app, in which games can be played; a smartwatch which monitor the arm function of the patient and a virtual coach which will motivate the patient. However, this system is still being developed and it is unknown whether it meets the user requirements.

Therefore, the goal of this study is to identify factors for NEST to maximize usability, acceptance and usefulness by stroke patients, therapists and caregivers in the home situation. We conducted a qualitative focus group study, with 5 patients, 5 caregivers and 5 therapists in each of the three centers in Italy, Spain and the Netherlands. In each of the three centers, 3 focus groups or interviews will take place; one with patients, one with caregivers and one with therapists. First an introduction will be given in which the participants will see a video of NEST. Then questions about the systems will be asked. In total this will take 2 hours with a 30-minute break for patients. The main objective of this study is to get a list with factors that NEST needs to fulfill in order for it to be used by patients, caregivers and therapists. This will come out of an inductive thematic analysis from the focus groups.
