Experimental Evaluation of Technical Gesture Analysis in Para-Standing Tennis

This pilot study investigates the use of wearable inertial sensors for technical gesture analysis in Para-Standing Tennis (PST), an emerging discipline involving athletes with physical impairments competing in a standing position. Forehand and backhand strokes were analyzed in two PST athletes with different impairment profiles using sensors mounted on the wrist and racquet. Acceleration and angular velocity signals were compared to assess the biomechanical information provided by the two sensing locations. Results showed that wrist- and racquet-mounted sensors capture different but complementary aspects of stroke execution, enabling the identification of distinct movement strategies associated with different impairment profiles. These preliminary findings support the potential of wearable sensors for objective biomechanical assessment in PST .
