Brief Summary

Recent research has found that there is moderate evidence for the use of breathing exercises for treating chronic, non-specific low back pain. Researchers have found that there were significant improvements in pain and quality of life in those suffering with low back pain who completed a breathing program intervention. Researchers also found that healthy individuals had higher pain thresholds and tolerance following deep and slow breathing exercises.

There are numerous formats of breathing interventions, some interventions that have been used with individuals with chronic, non-specific low back pain include: deep breathing, yoga breathing, resisted inspiration, and breathe holding. There is moderate evidence to suggest the use of these interventions for managing chronic low back pain Another common breathing format is Equal-Ratio Breathing. This format requires an individual to inhale and exhale with the same duration while gradually increasing the duration of both. This breathing format can be easier for patients to perform given the simplicity of the equal inhalation to exhalation ratio.

This research is being done because Equal-Ratio Breathing has yet to be studied in individuals with chronic low back pain.

Conditions

Chronic Low Back Pain

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Equal Breathing

Group Type: EXPERIMENTAL

Equal Breathing

Intervention Type: OTHER

• Blood pressure recorded at baseline, immediately pre- and post-trial
• Maximum Tolerable Breathing Ratio: Test run to determine the maximum tolerable time for inhalation and exhalation.
• PRESSURE TOLERANCE: Pressure algometer device used to determine pain pressure tolerance. It will be applied to the first dorsal interosseous and deltoid, and pain pressure tolerance will be measured and recorded. Pressure will be applied at 1kg per second until the patient indicates that the pressure has become painful. Pain pressure tolerance will be performed 3 times at each anatomical location and an average will be determined for each location.
• TRIAL: Participants will begin 5 minutes of Equal Breathing at their maximum tolerable equal breathing ratio that was previously determined. Immediately after 5 minutes of breathing, the pain pressure tolerance will be measured using pressure algometry
