The experimental group (EXP Group) is going to follow a programme of stabilisation through specific therapeutic exercises of the lumbopelvic centre. Two weekly sessions will be programmed for 12 weeks, making a total of 24 sessions. Each sesión will have a duration of 60 minutes, the first 5 minutes for a warm-up and the last 10 for a cool-down phase of active stretching. All patients will start learning how to activate the abdominal muscles in the first training session. The exercise progression will be adapted according to the capacity of each patient, considering their pain levels. The exercices will be made in 1 to 3 series of among 8 and 15 repetitions and the isometric contractions for 5 to 10 seconds. The rests between series will be of 30 seconds, and between exercies of 2-3 minutes.

Additionally to the core exercises previously exposed in Group EXP, Group MT will lay on the stretcher first, where the physiotherapist will work on a manual therapy thrust. The patient will receive an impulse technique in lateral decubitus position, with high velocity and low range on both sides.

The experimental group plus kinesio tape (KT Group) will go previously through physiotherapy, where a kinesio tape band will be applied (kinesio tape "Nondolens" 5cm x 5cm black color), in Y technique, by applying the KT base in neutral position of the lumbar spine without any tension on the tape.

All patients will start learning how to activate the abdominal muscles in the first training session. The exercise progression will be adapted according to the capacity of each patient, considering their pain levels. The exercises will be made in 1 to 3 series of among 8 and 15 repetitions and the isometric contractions for 5 to 10 seconds. The rests between series will be of 30 seconds, and between exercises of 2-3 minutes.

The Oswestry (ODI) test will be made to all participants at three months. The results of this scale will provide the necessary information to know the degree of symptomatology of the patient and will therefore help in the planification and procedure to the patient. That is why, it has been established that all participants in Stage 1 of the test are subsidiaries to make all the treatment modes of the study (manual therapy and exercise). This way, we are able to rise the homogeneity that imposes a diagnostic label such as the chronic low back pain.

The mostly used questionnaire to evaluate kinesiophobia is the TKS (Tampa Kinesiophobia Scale) questionnaire, which we will use to measure which is the fear to movement of patients of low back pain. This scale includes work related lesions, lesions due to repetitive effort, relapses and the avoidance-fear. The questionnaire is composed of 17 items in which there is a differentiation between the negative an positive elements.

This questionnaire will be filled in based on a Likert scale which ranges between 0 and 5, being 0 never and 5 always. The total punctuation ranges between 17 and 68, the higher the rate, the higher the degree of kinesiophobia.
