Low Back PainNCT01541020
Inspiratory Resistive Loading and Proprioceptive Postural Control
An observational study of Low Back Pain and Respiratory Loading, run by KU Leuven at 1 site in Belgium.
Trial summary
Proprioceptive weighting changes may explain differences in postural control performance. In addition, the respiratory movement has a disturbing effect on postural balance. Postural balance seems to be impaired in individuals with respiratory disorders. Read more about this study

About this study
Official title: Inspiratory Resistive Loading and Proprioceptive Postural Control in Healthy Individuals and Individuals With Recurrent Low Back Pain
Proprioceptive weighting changes may explain differences in postural control performance. In addition, the respiratory movement has a disturbing effect on postural balance. Postural balance seems to be impaired in individuals with respiratory disorders. Besides the essential role of respiration, the diaphragm may also play an important role in the control of the trunk and postural balance. Deficits in proprioception are found in a subgroup of patients with low back pain. In addition, disorders of respiration have been identified as strongly related to low back pain.
The aim of the study is to clarify whether loading of the inspiratory muscles has a negative effect upon proprioceptive postural control in healthy individuals and individuals with recurrent low back pain.

| Healthy individuals | Not described | |
| Individuals with low back pain | Not described |
What is being measured
The primary outcome is the main question the study is designed to answer.
Proprioceptive postural control
Center of pressure displacement (force plate) in standing in response to local muscle vibration on ankle and back muscles to specifically detect the role of proprioception in postural control.
Measured: 1 year
Secondary outcomes (3)
Back muscle oxygenation
Near infrared spectroscopy: tissue oxygenation index (TOI) and haemoglobin
Measured: 1 year
Kinematics
piezoresistive accelerometers
Measured: 1 year
Respiratory muscle force
maximal inspiratory pressure - maximal expiratory pressure
Measured: 1 year

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?
Proprioceptive postural control (time frame: 1 year). 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 NCT01541020, which also lists 1 linked publication.
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.
