COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
Osteopathic treatment: Rotation sitting impulse technique of the dorso-lumbar junction bilaterally
technique of high velocity, low amplitude in the dorso-lumbar junction known in osteopathy as "Fryette modified technique for dysfunction in T12 ERS." The aim of the technique is to increase lung volumes by restoring mobility at this level, where the diaphragmatic pillars are originated.
Subject Position: Sitting, hands placed like lift-off technique. Therapist position: forward to a side of the subject.
Contacts: pectoral contact on the outside of the upper side of the subject, locking the trunk. The previous hand contact on the back of the shoulder encircling the trunk of the subject and the elbow raised to rest his forehead. The back hand takes a pisiform contact ulnar border of the hand on the nested facet of T12
The technique is administered on a single occasion, but bilaterally
The duration of the tecnique is less than a minute (30 seconds approximately)

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The method of allocation concealment used wwas central randomsation by computer.
Subjects were randomly assigned to study groups using a table of random numbers generated by a computer, once it was found that the subject met the inclusion and exclusion criteria for participation in the study.
6 sequences encoded characters (A, B) replacing the random numbers, in which A represents the experimental group and B represents control group were used. The randomization sequence was guarded at all times by the principal investigator.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomization using a randomisation table generated by a computer
Masking / blinding

Statistical methods / analysis
To calculate the sample size formula for estimating proportions was used. The study population was 63,566 subjects (estimated from prevalence data of 4.4% between the ages 18-44 years in Madrid population). An error of 13.5% and a confidence interval of 95% was assumed. The formula for calculating the sample size has the following mathematical expression:

k(2) * P *Q 1,96(2) * 0,5 * 0,5
n = --------------- = -------------------------- = 52,71 ˜ 52
e(2) 0,135(2)

k = constant for 95% = 1.96
P = proportion of individuals that possess the property of the population = 0.5
Q = 1 - P = 1 to 0.5
e = MPE = 13.5%
Therefore, the appropriate sample size for the study was 52 subjects.

Statistical analysis was performed using SPSS version 19.0 program. There has been a statistical description of the bulk sample, and one each of the study groups. The Kormogorov-Smirnov test was used to verify whether or not data fit a normal distribution.
In the intragroup analysis, as proof of hypothesis testing for comparing scores pre-intervention and post-intervention Student t test for related samples was performed for both GE and GC. For the intergroup analysis, the Student t test for independent samples, where the differences between the post-intervention measures were contrasted minus pre-intervention between GE and GC measures. A confidence interval of 95%, so that is considered statistically significant values are those established as p <0.05

Brief summary
Objectives: To assess the possible variations of FVC, FEV1, FEV1/FVC ratio, PEF and MiniAQLQ quality of life questionnaire after the application of the rotation sitting impulse technique of the dorso-lumbar junction in asthmatic subjects.

Hypothesis: The application of the rotation sitting impulse technique of the dorso-lumbar junction in asthmatic subjects produces statistically significant changes on spirometric values for forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC ratio, peak expiratory flow (PEF) and MiniAQLQ quality of life questionnaire.
