- University of Wisconsin, Milwaukee
- Brief Summary
This proposed study will evaluate whether a novel nonpharmacological intervention, Breathing Room, can improve lung function in the target population of older adults. Therefore, the primary aim of this pilot is to examine the effect of Breathing Room on inspiratory muscle strength, spirometry confirmed ventilatory function (Forced Expiratory Volume in one second (FEV1), Forced Vital Capacity (FVC) and FEV1/FVC), functional status, posture, physical activity, and lower respiratory infection rates.
- Detailed Description
Restrictive ventilatory patterns (RVPs) contribute to two prevalent problems in older adults: 1) the development of pneumonia and other lower respiratory infections; and 2) declining endurance for physical activity. The Breathing Room was developed as an exercise activity designed to open the thoracic cage, increase strength of the muscles of respiration with inspiratory muscle trainers, and optimize the breathing technique.
This will be a pretest-posttest design in which the outcomes are measured at baseline, and at two weeks and four weeks post start of Breathing Room intervention. Breathing Room classes will be held 3 times a week for 4 weeks (2 group classes, 1 individual reinforcement of Inspiratory Muscle Training \[IMT\] homework). The IMT homework includes 3 days 5 cycles of 5 breaths, each cycle followed by 2-minute rest. The IMT will be also utilized during the 2 group classes.
The group classes will be conducted with a maximum of 5 participants in each group. Data on inspiratory muscle strength, spirometry confirmed ventilatory function (Forced Expiratory Volume in one second (FEV1), Forced Vital Capacity (FVC) and FEV1/FVC), functional status, posture, and physical activity will be collected. Infection rate data for each resident for 4 months following completion of Breathing Room will be also collected.

- Primary Outcome Measures
Name Time Method Change in inspiratory muscle strength At baseline, after 2 weeks intervention, after 4 weeks intervention MicroRPM Respiratory Pressure Meter will be used to assess changes in inspiratory muscle strength pre and post intervention. The sniff nasal inspiratory pressure (SNIP) scores will be recorded pre and post intervention.
Change in functional capacity At baseline, after 2 weeks intervention, after 4 weeks intervention The 6 Minute Walk Test will be used to assess the change in functional capacity and endurance pre and post intervention. The distance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity.
Change in grip Strength At baseline, after 2 weeks intervention, after 4 weeks intervention A JAMAR hand dynamometer will be used to assess changes in grip strength pre and post intervention. Measurements will be recorded using participants' dominant and non-dominant hand and repeated 3 times to determine maximum grip strength.
Change in forced vital capacity (FVC) At baseline, after 2 weeks intervention, after 4 weeks intervention Spirometry testing will be performed using the MicroLoop battery operated portable spirometer to assess changes in forced vital capacity (FVC) pre and post intervention
Change in forced expiratory volume in one second (FEV1) At baseline, after 2 weeks intervention, after 4 weeks intervention Spirometry testing will be performed using the MicroLoop battery operated portable spirometer to assess changes in forced expiratory volume in one second (FEV1) pre and post intervention
Change in forced expiratory volume in one second/forced vital capacity (FEV1/FVC) ratio At baseline, after 2 weeks intervention, after 4 weeks intervention Spirometry testing will be performed using the MicroLoop battery operated portable spirometer to assess changes in forced expiratory volume in one second/forced vital capacity (FEV1/FVC) ratio pre and post intervention
Chane in kyphosis index At baseline, after 2 weeks intervention, after 4 weeks intervention The flexicurve method will be used to measure the change in the kyphosis index pre and post intervention. To calculate the flexicurve kyphosis index, the apex kyphosis height (B) is divided by the length of the entire thoracic curve (X) and then multiplied by 100 (B/X × 100).
The flexicurve ruler, which is a malleable band of metal covered with plastic and approximately 60 cm in length, will be used. The ruler can be bent in only one plane and retains the shape to which it is bent. The subject will be instructed to stand up straight and as tall as possible, and the flexicurve ruler will be aligned to the spine from C7 to T12. The ruler will be then placed flat on paper and its outline will be traced.
