About this study
Official title: New Back. Analysis of the Acute and Chronic Effects of a Program of Body and Postural Work Through "Xiaxi Aligns Your Health"
Progressive deformity from the optimal spinal curvatures is a degenerative disorder related to progressive ageing that affects an increasing number of adults. This is one of the main affectations on the health of adults, being its cause multifactorial. That is why a totally effective intervention has not yet been found that allows obtaining a substantial improvement in all the adults who suffer from it. However, certain physical programs that include mind-body work have been effective, but research is limited and the results are inconclusive. For this reason, this research arises, in which a training protocol has been designed using an instrument called Xiaxi with which the body-mind work is prioritized.
The aims of this study were: 1) to evaluate the effects of a 12-weeks Xiaxi® exercise program on the sagittal spinal disposition and hamstring extensibility of adults, and 2) to determine whether the weekly training frequency influenced the changes found on sagittal spinal disposition and hamstring extensibility with Xiaxi® training program.
The present investigation is composed of two data collections that will be carried out before and after a twelve-week intervention. Two intervention groups and a control group make up the sample, with one of the intervention groups attending Xiaxi training once a week and the other intervention group twice a week. The control group will only attend the measurements, but will not participate in the intervention.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Xiaxi intervention programBehavioural
The Xiaxi sessions will follow the same structure in both intervention groups. First of all, 8-minute warm-up where the participants will work on: postural awareness; active static stretching of the pectoral, hamstring and psoas muscles; and mobility. The main part will include the following blocks of content during the 12 weeks of intervention (46 minutes will be spent on this part in each session): breathing; mobility; active and dynamic static stretching of the tonic muscles with effects on the spine dynamic; strength of the phasic muscles with effects on the spine dynamic, alternating upper limb, lower limb and core; postural awareness; and passive static stretching of the tonic muscles with effects on the spine dynamic. The cool down will be similar in each session (6 minutes) and will focus on: postural awareness and passive static stretching of the pectoral, hamstring and psoas muscles.
| Study group | Role | What they receive |
|---|---|---|
| Experimental group who trained one day a week | Experimental | This intervention group will attend a weekly sixty-minute training session with the Xiaxi machine during the twelve weeks of the intervention. The sessions will include flexibility and strength-resistance work, as well as postural awareness. Receives: Behavioral: Xiaxi intervention program |
| Experimental group who trained two days a week | Experimental | This intervention group will attend two weekly sixty-minute training sessions with the Xiaxi machine during the twelve weeks of the intervention. The sessions will include flexibility and strength-resistance work, as well as postural awareness. Receives: Behavioral: Xiaxi intervention program |
| Control Group | No intervention | They will not attend any type of intervention. They will continue to perform their daily activities without intervention. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Sagittal spinal curvature in relaxed standing
The thoracic angle, lumbar angle and pelvic tilt will be measured with the subject in a standing position, adopting the usual and daily position. The unit of measurement will be the same, using the grades achieved.
Measured: Up to 12 weeks
Sagittal spinal curvature in active alignment in standing
The thoracic angle, lumbar angle and pelvic tilt will be measured with the subject in a standing position, but in this case the subject will be asked to rectify the arrangement of the spine to be as straight as possible. The unit of measurement will be the same, using the grades achieved.
Measured: Up to 12 weeks
Sagittal spinal curvature in relaxed sitting
The thoracic angle, lumbar angle and pelvic tilt will be measured with the subject in a seated position, maintaining a habitual, everyday position. The unit of measurement will be the same, using the grades achieved.
Measured: Up to 12 weeks
Sagittal spinal curvature during Macrae & Wright test
The thoracic angle, lumbar angle and pelvic tilt will be measured with the subject performing the Macrae \& Wright test, in which the subject will be asked to perform maximum trunk flexion from a seated position. The unit of measurement will be the same, using the grades achieved.
Measured: Up to 12 weeks
Sagittal spinal curvature during sit and reach test.
The thoracic angle, lumbar angle and pelvic tilt will be measured with the subject performing the sit and reach test, in which the subject will be asked to perform a maximum trunk flexion from a seated position and with the soles of the feet resting on a box, keeping the knees fully extended during the same, to push a ribbon the maximum distance through the box. The unit of measurement will be the degrees of the curvatures of the back, as well as the distance reached in the test.
Measured: Up to 12 weeks
Sagittal spinal curvature during toe touch test
The thoracic angle, lumbar angle and pelvic tilt will be measured with the subject performing the toe touch test. In this test, the subject will be asked to perform a maximum trunk flexion in which he/she will try to reach the maximum possible distance from a standing position on a box. The knees will be kept fully extended during the test and an attempt will be made to reach the feet, and this distance may be exceeded if necessary. The unit of measurement will be the degrees of the curvatures of the back, as well as the distance reached in the test.
Measured: Up to 12 weeks

Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Sagittal spinal curvature in relaxed standing (time frame: Up to 12 weeks). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06042218, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2023; AzTrials last refreshed its copy on 26 Oct 2026.
