Lumbopelvic Movement Control: Effect of Injury History, and the Role of Cortical Control and Its Practical Application 2

Restoration of Lumbopelvic Movement Control: Effect of Injury History, and the Role of Cortical Control and Its Practical Application(2)

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: motor imagery with action observation; The subjects will perform the exercises mentally for 3 sets with video, 10 reps for 1 set.	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.
Experimental: physical training; The subjects will perform the exercise physically for 3 sets with supervision of investigator, 10 reps for 1 set.	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.
Experimental: combine physical training and motor imagery with action observation; 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; 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	immediately after the intervention
