BACKGROUND: ROBiGAME project aims to implement serious games on robots to rehabilitate upper limb (UL) in stroke patients. The serious game characteristics (target position, level of assistance/resistance, level of force) are adapted based on the patient’s assessment before and continuously during the game (measuring UL working area, kinematics and muscle strength). OBJECTIVE: To develop an UL robotic motor assessment protocol to configure the serious game. METHODS: 32 healthy subjects and 20 stroke patients participated in the study. Subjects were clinically assessed (UL length and isometric force) and using a robot. The robot assessment consisted of the patient’s UL working area (WA), the UL isometric and isokinetic force in three directions and the UL kinematics during a pointing task toward targets placed at different distances. RESULTS: The WA and the UL isometric force were moderately to highly correlated with clinical measures (respectively ρ = 0.52; p = 0.003, ρ = 0.68–0.73; p < 0.001). Ratios between the UL isokinetic force generated on three directions were established. The velocity and straightness indexes of all subjects increased when subjects had to reach to targets placed more distantly (r = 0.82–0.90; ρ = 0.86–0.90 respectively; p < 0.001). AUTHOR COPY CONCLUSIONS: This protocol can be integrated into a serious game in order to continuously configure the game charac- teristics
