NCT02429752

Brief Summary

The goal of this study is to identify if there is a significant prevalence of abnormal respiratory patterns in a sample of patients with low back pain (LBP), and if the presence of abnormal respiratory patterns are predictive of rehabilitation outcomes in this population. In addition, the investigators will assess the response to inspiratory muscle training (IMT) for a subgroup of subjects that maintain abnormal breathing patterns after 1 month of physical therapy. Patients seeking physical therapy for LBP within the Uhealth system will be recruited. The first phase of this study will be observational. A comprehensive assessment of their respiratory function will be performed at the beginning of their therapy and after 1 month of therapy. Subjects that demonstrate abnormal respiratory patterns after 1 month of therapy will be offered the opportunity to participate in the second phase of the study in which they will receive 1 month of inspiratory muscle training (IMT). The respiratory assessment will then be repeated at the end of the IMT training program.

Outcome Measures

Primary Outcomes (1)

  • Change in baseline value of breath-by-breath gas analysis

    Measure of breathing pattern and respiratory gases at rest and with activity

    baseline, after 1 month of therapy, after 2 months of IMT

Secondary Outcomes (5)

  • Number of Participants improved on the Oswestry Disability Index

    baseline, after 1 month of therapy, after 2 months of IMT

  • Number of Participants improved on the Numeric Pain Rating Scale

    baseline, after 1 month of therapy, after 2 months of IMT

  • Change in baseline value of Maximal inspiratory pressure

    baseline, after 1 month of therapy, after 2 months

  • Change in baseline value of sustained maximal inspiratory pressure

    baseline, after 1 month of therapy, after 2 months

  • Change in baseline value of maximal expiratory pressure

    baseline, after 1 month of therapy, after 2 months

Study Arms (1)

Inspiratory Muscle Training

EXPERIMENTAL

Subjects will receive 8 weeks of IMT

Other: Inspiratory muscle training

Interventions

Subjects that demonstrate unresolved BPD's upon reassessment after PT treatment, will have the option to participate in the second phase of the study. These subjects will be scheduled twice a week to receive IMT using the RT2 device and software program. The IMT protocol uses biofeedback to train at a specific percentage of MIP and SMIP for each inspiratory effort.
