Control group
Active

Outcomes
Primary outcome [1] 291646 0
To assess the effectiveness of the stretching diaphragm technique in patients diagnosed of chronic low back pain by comparing the results obtained in the expiratory peak flow with those obtained before the intervention.We used a spirometer.
Timepoint [1] 291646 0
Immediately after the intervention.
Primary outcome [2] 291647 0
To assess the effectiveness of the stretching diaphragm technique in patients diagnosed of chronic low back pain by comparing results obtained in the distance finger-floor technique with those obtained before the intervention. We used the fingertip-to-floor distance (FFD) test.
Timepoint [2] 291647 0
Immediately after the intervention
Secondary outcome [1] 307221 0
Low back pain is assessed using a Visual Analogue Scale (VAS) for the subjective perception of pain and compared with the results obtained before the intervention.
Timepoint [1] 307221 0
Immediately after the intervention
Secondary outcome [2] 307222 0
To assess the effectiveness of the stretching diaphragm technique in patients diagnosed of chronic low back pain by comparing results obtained Modified Schober test with those obtained before the intervention.
Timepoint [2] 307222 0
Immediately after the intervention.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Sealed opaque envelopes
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The allocation was determined by the election of cards of colors. Each patient shuffled the cards and randomly picked one of them upside down. All cards were different. The red and green colors indicated that the patient would be part of the study group while the cards yellow and purple corresponded to the control group.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
