Effects of Functional Upper Limb Task-Based Training on Initial Embodiment and Neuromuscular Control Efficiency of Supernumerary Robotic Limb : Pilot Study
This study investigated the effects of a complex activities of daily living (ADL)-based training program on muscle activation, task performance, and embodiment during the use of a supernumerary robotic limb (SRL). Five healthy adults participated in a single-group pre-post intervention study using a SRL system. Muscle activation was assessed by surface electromyography of the finger flexor (RMS_F) and finger extensor (RMS_E) muscles during a visual stimulus-based control task. Task performance was evaluated using a dynamic ball-catching task, and embodiment was assessed using an embodiment questionnaire. Data were analyzed using paired t-tests. Following the intervention, RMS_F significantly decreased from 72.20±11.71 to 33.50±6.05 (p=.002), and RMS_E significantly decreased from 71.10±24.82 to 41.55±12.16 (p=.024). Ball-catching success rate significantly increased from 34.80±7.77% to 61.33±8.81% (p<.001). Significant improvements were observed in embodiment questionnaire items related to ownership, visual matching, and proprioceptive matching (p<.05), whereas no significant change was found in tool perception (p=.162). These findings suggest that complex ADL-based training can improve neuromuscular efficiency, task performance, and embodiment during SRL use, supporting the potential application of SRLs in rehabilitation and human augmentation.
