Measurement of Changes in Chest Mobility and Pulmonary Functions in Relation to Stroke Patients’ Positions

Abstract

[Purpose] The purpose of this research was to study the changes in chest mobility and pulmonary functions in relation to stroke patients’ situation. [Methods] Twenty stroke patients participated in this experiment. Measurements were taken in the supine position, 45° sitting position leaning against a surface, and 90° sitting positions, in a random order. Chest mobility (during rest, during maximal inspiration, and during maximal expiration) in each position was evaluated using a tape measure, and pulmonary functions (vital capacity, inspiratory capacity, tidal volume, inspiratory reserve volume, expiratory reserve volume) were evaluated using a spirometer. [Results] The results show a significant differences in chest circumference during maximal inspiration for chest mobility between supine and sitting at 90°, and significant differences in tidal volume and vital capacity for the pulmonary functions among the three positions. [Conclusion] In conclusion, changing a stroke patient’s position produce changes in chest mobility and pulmonary functions. The greatest change occurred in the 90? sitting position. Presumably, ventilation is affected by gravity, The results will provide objective data for establishing stroke positions for stroke patients performing respiratory exercises.
