Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is performed by a physiotherapist.
The experimental group will be the placement of the blocks, 5 minutes in flexion and 5 minutes en extension. The base of the blocks are placed on the hip joints and the tips of the blocks towards the navel to bring the pelvis to flexion. To carry the pelvis to extension the base of the blocks is placed on the iliac crests and the tips towards the pubis.
The treatment is administered once in each participant.
The control group will remain without intervention for 10 minutes lying on the stretcher in the prone position. Once the study for the control group was concluded, the same treatment as that applied to the experimental group was obtained.
With the technique of blocks we intend to normalize the movements of the iliac crests, L4, L5 and sacrum and reduce the pain that is directly related by joints, ligaments, muscles and nerves.
The tests of orthopedic strength of the pyramidal muscles, gluteal medius, gluteus maximus and psoas-iliac according to Daniels will be used as diagnostic maneuvers. They will be measured with the force dynamometer by performing 3 repetitions of each test and obtaining the average value. The duration of each test will be 5 seconds.
The tests will be performed before and after the placement of the Dejarnette blocks and one week later of placement of the bloks.

Summary
Brief summary
The purpose of this study is to decrease the perception of low back pain and to improve the maximum strength of the lumbar muscles.
The hypotheses of the study are:
- Following treatment with Dejarnette blocks for 10 minutes, there is a significant increase in maximal strength of the pyramidal, gluteus medius, gluteus maximus and psoas-iliac muscles bilaterally.
- Following the treatment with Dejarnette blocks for 10 minutes, there is a significant increase in mean strength performed during the 5 second test before and after treatment of the pyramidal, gluteus medius, gluteus maximus and psoas-iliac muscles bilaterally.
- After treatment with Dejarnette blocks for 10 minutes, there is an improvement in the perception of immediate local pain using Visual Analogue Scale (VAS).
- After a week of treatment with Dejarnette blocks for 10 minutes, there is an improvement in local pain perception using Visual Analogue Scale (VAS).
- After one week of treatment with Dejarnette blocks for 10 minutes, there is an improvement in the perception of low back pain using the Roland Morris Questionnaire.
