Brief 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.

Outcome Measures

Primary Outcomes (5)

• Motor control ability

  The subjects will stand on Y-balance kit with their dominant leg and reach their non-dominant legs to anterior, posterolateral and posteromedial direction following the tempo with 5 sec forward and 5 sec backward in sequence. The subjects will practice 4 times first to familiarize the test procedure, then the final three measurements were collected and normalized with subjects' lower limb length for statistical analysis.

  pre-intervention

• Cortico-muscular coherence

  The investigator will place 64-leads EEG on subjects' head and bipolar surface EMG(MP150, BIONOMADIX; BIOPAC, Systems, Inc.) on subjects' internal oblique abdominis, gluteus medius, gluteal maximus and adductor longus. The investigator will collect the signals and process them into cortico-muscular coherence as the functional connection between cortex and muscle during motor control task.

  pre-intervention

• Task-related spectral power

  The investigator will collect the EEG signals from subjects during the intervention, and the signals will be band-pass filtered (3-60 Hz) and processed with power spectrum density analysis to calculate frequency power at alpha (8-12 Hz) and beta (13-30 Hz) bands. The training data will be normalized with resting values to determine task-related synchronization or desynchronization, which represent the cortical activation changes during training.

EXPERIMENTAL

The subjects will perform the exercise mentally with video for 1 set and physically with supervision of investigator for 2 sets, 3 sets totally, 10 reps for 1 set.

Other: combine physical training and motor imagery with action observation

Interventions

motor imagery with action observation OTHER

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.
