An exercise mat, a video connection and a carefully taught breathing cue may be enough to extend part of back-pain rehabilitation beyond the clinic, according to a small randomized trial testing two respiratory strategies alongside core-stability exercise.
Hui Zou and colleagues at Beijing Sport University and two Chinese rehabilitation research centers enrolled 54 people with chronic nonspecific low-back pain in an assessor-blinded study. Their trial, published online July 14 in Disability and Rehabilitation, compared diaphragmatic breathing, an abdominal drawing-in maneuver and core exercise without added breathing instruction.
All three groups completed a four-week hybrid program combining supervised and remotely delivered rehabilitation. Researchers measured pain and disability as the primary outcomes, with additional assessments of movement-related fear, quality of life, perceived recovery, proprioception and postural balance. Participants were followed for three months.
Both breathing groups reported greater short-term improvements in pain and functional disability than participants who performed core-stability exercise alone. Some effects remained at the three-month follow-up.
The breathing groups also showed greater improvements in movement-related fear, perceived recovery, proprioception and balance under eyes-closed conditions. The trial found no significant difference between diaphragmatic breathing and abdominal drawing-in, suggesting that neither method should be treated as the single correct pattern for every patient.
Diaphragmatic breathing emphasizes coordinated movement of the diaphragm, abdomen and lower rib cage. The abdominal drawing-in maneuver asks the patient to gently activate deeper abdominal muscles while limiting substitution by larger trunk muscles.
Both strategies were integrated with progressive exercise. The study therefore does not show that breathing alone treats chronic back pain. It tests whether respiratory and trunk-control instruction can add value to a rehabilitation program that already includes movement.
The physiological reasoning involves the diaphragm’s dual role. In addition to drawing air into the lungs, it contributes to pressure regulation and trunk stability. Abdominal muscles also participate in breathing and spinal control. Pain, guarding and fear of movement may disturb that coordination during exercise.
The trial did not establish that one abnormal breathing pattern causes chronic pain. Instead, it asked a more practical question: can patients learn to coordinate breathing and movement in a program delivered partly at home?
That hybrid format matters. Rehabilitation often includes periodic appointments followed by independent practice. A technique that works only while a clinician is physically correcting every movement has limited reach. Remote instruction may allow patients to continue a structured program while reducing travel and scheduling barriers.
The results also fit a broader, though still developing, evidence base. A 2025 systematic review and meta-analysis of breathing exercises for chronic nonspecific low-back pain examined diaphragmatic, slow, deep and forced-exhalation techniques. The variety of methods and treatment durations illustrates why breathing should be considered a rehabilitation component rather than one standardized intervention.
The new trial remains preliminary. Dividing 54 participants among three groups leaves relatively few people in each comparison, and a four-week intervention cannot establish long-term effectiveness. Researchers will need to determine whether the added improvements persist, whether participants continue using the skills correctly and which patients are most likely to benefit.
Adherence is particularly important in remote care. A participant can attend an online session without reproducing a movement or breathing cue as intended. Future trials should report how exercise quality was monitored and whether better performance at home was associated with better clinical outcomes.
The findings should not encourage people with unexplained or persistent back pain to replace assessment with a breathing routine. Back pain can have many causes, and symptoms such as progressive weakness, loss of bladder or bowel control, fever or major trauma require appropriate medical attention.
For clinicians, the useful result is flexibility. Some patients may coordinate movement more naturally with diaphragmatic breathing, while others may respond to a focused abdominal cue. The trial suggests either can be integrated into hybrid care without declaring one method universally correct.
The next test is transfer: whether respiratory-motor coordination learned on an exercise mat remains available when a patient lifts, walks, works or returns to recreation. That is where a breathing cue becomes functionally valuable—and where the added coaching time will ultimately have to justify itself.
