Summary

Hip motor control ability is an important parameter for preventing sport injuries in lower limbs, and the training of hip motor control can enhance the lower extremity movement performance. Previous studies have demonstrated the benefits of motor imagery with action observation (AOMI) on motor control and muscle strength improvements, which also revealed that AOMI combined with physical training (AOMI-PT) can lead to better outcomes than physical training (PT) alone. Besides, monitoring the neurophysiological changes of brain activation and the functional connection to the peripheral muscular activation after training helps to understanding the mechanisms on the training effects. Therefore, the aim of this study is to compare (1) the cortical control mechanisms between 3 types of motor control training strategies; and (2) the effects of 3 types of motor control training on hip motor control performance in healthy subjects.

Detailed description

Hip motor control ability is an important parameter for preventing sport injuries in lower limbs, and the training of hip motor control can enhance the lower extremity movement performance. Previous studies have demonstrated the benefits of motor imagery with action observation (AOMI) on motor control and muscle strength improvements, which also revealed that AOMI combined with physical training (AOMI-PT) can lead to better outcomes than physical training (PT) alone. Besides, monitoring the neurophysiological changes of brain activation and the functional connection to the peripheral muscular activation after training helps to understanding the mechanisms on the training effects. Therefore, the aim of this study is to compare (1) the cortical control mechanisms between 3 types of motor control training strategies; and (2) the effects of 3 types of motor control training on hip motor control performance in healthy subjects. The investigators will recruit 45 healthy subjects and compare the effect of three types of motor control training (physical training, motor imagery with action observation, physical training combined motor imagery with action observation) on Y balance test performance, cortico-muscular coherence (CMC), and task-related spectral power (TRSP) changes. Due to only few studies about the issue, we will recruit extra 15 healthy athletes for pilot study to investigate the reliability of the research measurements and refine the protocols. Chi squared test is used to examine the group differences such as gender, dominant side and activity level. The 2-way mixed analysis of variance (ANOVA) will be used to compare the intervention effect on motor control test and CMC between groups. One-way repeated measures ANOVA will be used to investigate the neurophysiological changes on brain activation during AOMI training, and the changes of AOMI-PT and PT group will be compared by independent t-test. The alpha level was set at 0.05.

Interventions

Type	Name	Description
OTHER	motor imagery with action observation	Standing clamshell exercise with elastic band, sliding, and Romanian deadlift exercise will be instructed to the subjects with video, and they will practice each exercise for 3 times in physical to familiarize with the program. Then, the subjects will mentally simulate each exercise with video 10 times for a set, 3 sets totally. With 2 min interval between each sets, it will take approximately 8 minutes to finish each movement. It will also take 3 min for resting between each program.
OTHER	physical training	Standing clamshell exercise with elastic band, sliding, and Romanian deadlift exercise will be instructed to the subjects with video, and they will practice each exercise for 3 times in physical to familiarize with the program. Then, the subjects will physically perform each exercise with supervision of investigator 10 times for a set, 3 sets totally. With 2 min interval between each sets, it will take approximately 8 minutes to finish each movement. It will also take 3 min for resting between each program.
