The work presents the exploration of the feasibility of two forms of biofeedback to obtain a within-session reduction of the Soleus stretch reflex with conditioning. First, we explored the feasibility of gamification and second, the feasibility of combined game- and impedance-based biofeedback.

In short, we showed feasibility of EMG-, game-based biofeedback within the operant conditioning paradigm, which calls for further research on gamification of conditioning paradigms to obtain improved participant motivation and engagement, while achieving long-term conditioning effects. Contrarily, the use of impedance-, game-based biofeedback did not result in a feasible conditioning paradigm, thus the time-intensiveness and slow learning curve of the conditioning paradigm remain an open challenge.
