NCT00629850

Brief Summary

The purpose of this study is to determine if the use of a respiratory resistance trainer will increase respiratory muscle strength, improve sleep quality and improve quality of life in individuals with spinal cord injury. Hypothesis: Use of the respiratory resistance trainer will improve respiratory muscle strength, improve sleep quality, and improve quality of life among individuals with spinal cord injury.

Outcome Measures

Primary Outcomes (3)

  • Number of Participants With Improvement in Sleep Quality.

    Improvement in sleep quality as defined by: less fragmented sleep, lower apnea hypopnea index (AHI), respiratory disturbance index (RDI) after device use.

    10 weeks

  • Change in Maximum Voluntary Ventilation Using Pulmonary Function Device

    Pulmonary function device measures flow rate in liters per minute over a period of at least 12 seconds.

    10 weeks

  • Change in Negative Inspiratory Force Using a Pressure Manometer

    10 weeks
