“…The quality of being distinct of motor imagery was to converge the excitability of spinal motor neuron and improve motor performance [13]. And, our previous study [42] reported that motor imagery might improve expeditiousness. It is considered that the composite for kinesthetic and visual motor imagery might be improving quality of being distinct of motor imagery.…”

Motor imagery can be helpful for the therapeutic approach for the patients who have difficulty in the actual motion. This chapter explains the following important six points for getting high-effective motor imagery based on the neuroscience. First, excitability of spinal motor neuron was increased by motor imagery. However, adding effect on breathing state, both expiration and inspiration phase on the relax respiration, does not influence the excitability of spinal motor neuron. Also, motor imagery increased the excitability of spinal motor neuron and cardiac sympathetic nerve activity. However, vividness of motor imagery was to converge a degree. Motor practice before motor imagery was important. Motor practice was appropriate for 30 s using intermittent visual feedback, and for doing motor imagery, time enough was 1 min. Adding motor imagery method was a recommended composite for kinesthetic and visual motor imagery. Unfortunately, motor imagery has few effects for the other hand. Therefore, motor imagery should be done on the ipsilateral side from the previous motor practice.

“…Then, they were asked to practice the pinching movement repeatedly for 30 s while quickly adjusting to 50% MVC by referring to the display of the digital pinch meter. For the practice session, 6 sequences were set up with an interval of 5 s during which the participants had to adjust to 50% MVC within a maximum of 5 s. After adjustment for 50% MVC, the participants had to decompress and prepare for the next sequence by performing 6 repetitions in 30 s, which was enough practice 6 . In pinch task 1, the participants were instructed to adjust to 50% MVC as quickly as possible while observing the display.…”

“…Moreover, upper limb function in patients with poststroke hemiparesis was improved after a combination of physical therapy and MI 5 . In our previous study 6 , we compared precision pinch force control after MI in healthy participants. Our previous study compared the pinch force deviation from the specified target value between before and after MI.…”

Kinesthetic motor imagery (KMI) involves imagining the feeling and experience of movements. We examined the effects of KMI, number visualizing, and KMI with number visualizing on the excitability of spinal motor neurons and a behavioral outcome measure in a pinch force task. Healthy participants (13 men and 8 women; mean age: 24.8 ± 5.5 years) were recruited. We compared the F-waves of the left thenar muscles after stimulating the left median nerve at the wrist during each motor imagery condition after a practice session. The KMI condition consisted of imagining muscle contraction, the number visualizing condition consisted of imagining the pinch force increasing numerically, and the KMI with number visualizing consisted of alternating between the KMI and imagining the pinch force increasing numerically. Before and after motor imagery, the time required to adjust to the target pinch force was compared. The time required to adjust the pinch force was shorter in the KMI with number visualizing condition than in the KMI and number visualizing conditions. There was no difference in the F/M amplitude ratio between each MI strategy condition, indicating the excitability of spinal motor neurons. Numerical information helped to improve the ability of participants to perform KMI.
