The Effect of Inspiratory Muscles Fatigue on Postural Control in People With and Without Recurrent Low Back Pain

After inspiratory muscles fatigue (IMF), control subjects use a rigid proprioceptive postural control strategy, rather than the normal “multisegmental” control, which is similar to people with low back pain (LBP). This results in decreased postural stability. These results suggest that IMF might be a factor in the high recurrence rate of LBP.
