Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The treatments will be carry out during 2 sessions a week/ 3 weeks and there will be 1 check-up 1 month after the last session (total duration of the study: 7 weeks). To develop this study 2 professional will be needed (both professionals are physiotherapists):
- The first professional (P1) will do the selection the sample and the evaluation.
- The second professional (P2) will do the randomisation into 2 groups and the treatment.

The treatments will be:
Each patient will be randomly assigned one of two treatments. Both groups will receive the same Manual Therapy Program by the second professional (physiotherapist with more than 5 years experience).

The Manual Therapy Program has duration of 30 minutes.
- Passive mobilizations: 2 sets of 10 flexion mobilizations, 10 extensions, 10 abductions, 10 adductions, 10 internal rotations and 10 external rotations.
- Massage with movement: massage at muscles of low back pain from craneal to caudal while the patient makes an active anterior flexion (3 times).
- Passive stretching: physiotherapist takes both patient´s legs and she does a flexion in order to approximate the knees of the patient to his breast (3 times of 1 minute).
- Pressure release: at myofascial trigger points of quadratus lumborum (3 cycles each point with a maximum of three).

Active exercises: patient lies in a pad with knees´s flexion. 10minutes.
- Patients make little steps from right to left (lateroflexion). 1 set of 10 times.
- Patients drop his legs to both sides (rotation). 1 set of 10 times.
Active exercises: patient in cuadrupedia.5 minutes.
- Cat-horse: take the whole column to flexion and extension respectively. 1 set of 10 times.

All exercises have a comfortable intensity without pain, just muscular tension.
The difference between groups will be that one of them will additionally receive a neuromuscular bandage at the end of the session (after the treatment and the exercises).
.
Neuromuscular bandage will be placed by a physiotherapist at paraspinal low back muscles: 2 vertical strips without tension and one transversal strip with 50% of tension. Patients have to make an active anterior flexion to place it and thy have to keep it during 4 days.

Comparator / control treatment
Control group will have the same Manual Therapy Program but they will receive a false neuromuscular bandage.

This tape bandage haven´t the properties of the neuromuscular bandage, It is not elastic and his application has no tension. On the other hand .the strips have the same place in both groups.
Control group
Placebo

Statistical methods / analysis
Since no previous studies that allowed us to determine the sample size of the study, a pilot study with 11 patients in each group was performed. We used the mean and standard deviation of the primary outcome (improvement in pain) in the control group , the average was 6,636 (1,566 DT) and at the case group was 8 (DT 1,183) . Under these conditions the effect size or standardized mean difference (Cohen's d) was equal to 1.03038. We used Gpower program and we considered an alpha error of 0.05 and 80% of power, the sample size required was 26 subjects (13 in each group) .

The statistical tests we have chosen are:

A Friedman test and a Dunn test: to see the difference between the initial and final average of each variable in the same group.
A t-student test for independent samples: to see the difference between the initial and final average of each variable between groups.
