Brief Summary:
Motor imagery is defined as a dynamic mental process of an action, without its real motor execution. Action observation evokes an internal, real-time motor simulation of the movements that the observer is perceiving visually. Both MI and AO have been shown to produce a neurophysiological activation of the brain areas related to the planning and execution of voluntary movement in a similar manner how the real action.

Official Title: Efficacy of an Intensive Exercise Program Combined With Training on Action Observation and Motor Imagery for Improving Lumbopelvic Motor Control and Strengthening Trunk Muscles: A Randomized Controlled Trial

Actual Primary Completion Date : May 30, 2018
Actual Study Completion Date : December 1, 2018

Arm Intervention/treatment
Experimental: Motor imagery
All the subjects in this group were informed of the procedure at the beginning of the intervention, which consisted of the following: in the first phase (the first week), all participants had to perform the same motor control exercises program than the control group, but previously, a mental practice based on kinesthetic mental motor imagery was performed. To reinforce the process of motor imagery, a video with the exercises was shown to the subjects before performing the mental practice. All subjects had to imagine that he/she was performing each exercise during 1 set of 12 repetitions prior to the real execution of this. During the second phase (the second and third week), subjects had to complete the set both imagining, with visual mental motor imagery, and actively performing the exercises.
Behavioral: motor imagery
All subjects had to imagine that he/she was performing each exercise during 1 set of 12 repetitions prior to the real execution of this. During the second phase (the second and third week), subjects had to complete the set both imagining, with visual mental motor imagery, and actively performing the exercises.

Experimental: Action observation

All the subjects in this group were informed of the procedure at the beginning of the intervention, which consisted of the following: in the first phase (the first week), all participants had to perform the same motor control exercises program than the control group, but prior to the real execution, a video was shown in third-person perspective. All subjects watched one person performing each exercise during 1 set of 12 repetitions. During the second phase (the second and third week), subjects had to perform actively the exercises while they watched the video.

All the participants also received a booklet with written information about the indications and exercises to be practiced at home to ensure that the training program was performed properly. Each week, participants received messages to remind and motivate them to undertake the exercise program daily.

Behavioral: Action observation
A video was shown in third-person perspective. All subjects watched one person performing each exercise during 1 set of 12 repetitions. During the second phase (the second and third week), subjects had to perform actively the exercises while they watched the video.

Active Comparator: Control group
The subjects in this group received an intensive training program based on stabilization exercises of lumbo-pelvic region, which are common exercises used in rehabilitation of patients with chronic non-specific low back pain.
Behavioral: Motor Control Exercises
The subjects were asked to perform 3 sets, of 10-12 repetitions each six exercise, with a total duration of approximately 30-35 minutes. The exercises program had to do it once a day, 6 days a week, for 3 weeks.




Primary Outcome Measures :
  1. Changes in the Right Lumbo-pelvic motor control [ Time Frame: 1 week and 3 weeks ]
    Lumbar motor control will be measured by a pressure biofeedback called Stabilizer TM. The measurement protocol in the following procedure; The patient should be supine position with the Stabilizer TM placed in the lumbar region with an initial pressure of 70 mmHg. Then, the patient will be asked to flex the hip and knee at 90 ° with one leg and then with the opposite one. It is a validated and reliable protocol for motor control of the lumbar region

  2. Changes in the Left Lumbo-pelvic motor control [ Time Frame: 1 week and 3 weeks ]
    Lumbar motor control will be measured by a pressure biofeedback called Stabilizer TM. The measurement protocol in the following procedure; The patient should be supine position with the Stabilizer TM placed in the lumbar region with an initial pressure of 70 mmHg. Then, the patient will be asked to flex the hip and knee at 90 ° with one leg and then with the opposite one. It is a validated and reliable protocol for motor control of the lumbar region


Secondary Outcome Measures :
  1. Perceived fatigue: changes in the Visual Analogue Scale-fatigue mid-intervention [ Time Frame: 1 week and 3 weeks. ]
    Perceived fatigue will be measured with Visual Analogue Scale (VAS). The VAS consists of a 100-mm line, the left side of which represents "no fatigue" whereas the right side represents "maximal fatigue"

  2. Changes in the trunk muscles strength [ Time Frame: 1 week and 3 weeks. ]
    The strength of the lumbar region will be measured by a foot dynamometer (Takei TM 5420). The patient should stand on the dynamometer platform with knees extended, elbows extended, hips bent and index fingers holding the bar at knee height. Starting from this position the subject will have to make a previous adjustment of contraction of the musculature of the lumbar region and must perform a movement of lumbar extension. Subjects should maintain contraction for 3 seconds. It is a valid and reliable test to measure the muscular strength of the lumbar region
