AB  - Action observation (AO) and motor imagery (MI) are potential methods to improve 
      various motor functions. AO and MI facilitate corticospinal excitability. 
      Additionally, the combination of AO and MI (AO + MI) facilitates greater 
      corticospinal excitability than AO alone. However, it is unclear whether AO + MI 
      facilitates the excitability of spinal motor neurons better than AO alone. Thus, 
      in this study, we compared the excitability of spinal motor neurons between 
      AO + MI and AO conditions using F-waves. We recruited healthy adult volunteers 
      (n = 31) for F-wave analysis. We recorded F-waves during relaxation to determine 
      the baseline level (Rest), followed by measurement during AO and AO + MI. To 
      counterbalance the order effect, 15 participants performed AO first, while the 
      others performed AO + MI first. F-wave persistence was significantly increased 
      during AO and AO + MI compared to Rest. The F-wave/M-wave amplitude ratio was 
      significantly increased during AO + MI compared to Rest. The present results 
      suggest that the combination of AO and MI facilitates the excitability of spinal 
      motor neurons compared to Rest, whereas AO alone does not.
