Summary

The purpose of this study is to evaluate the intra-rater and inter-rater reliability of diaphragm thickness and excursion measurements by applying Rehabilitative Ultrasound Imaging (RUSI) in a diverse cohort of healthy women, including nulliparous and parous across varying age groups.

The diaphragm, which is primarily a respiratory muscle, is also considered to contribute to spinal stability. Utilizing RUSI, a non-invasive and cost-effective imaging modality, we intend to examine diaphragm parameters. Preliminary evidence highlights a potential link between diaphragm dysfunction and musculoskeletal conditions such as lumbopelvic pain. This research hypothesizes that understanding diaphragm behavior in different pathologies, including postpartum recovery and lower back pain, can contribute to tailored rehabilitation strategies, potentially benefiting a wide range of clinical conditions, and facilitating the assessment of intervention effectiveness. Additionally, this study addresses the lack of research on the diaphragm's role in postpartum rehabilitation and offers novel insights into its reliability, particularly within this demographic.

DIAGNOSTIC_TEST

Diagnostic Ultrasound Imaging of the diaphragm

In this reliability study, ultrasound imaging will be utilized by trained physiotherapists to assess diaphragm thickness and excursion. Participants will be positioned in a semi-recumbent position, while the scanning area will be marked with a surgical skin marker according to specific anatomical landmarks recommended, to ensure reproducibility of the procedure. Ultrasound probe will be placed at the zone of apposition to visualize the diaphragm through the liver window. Diaphragm thickness will be assessed during both full inhalation and exhalation, capturing images in B-mode to measure distance between the diaphragmatic pleura and peritoneal fascia. Diaphragm excursion will be assessed during tidal volume diaphragmatic breathing, using M-mode to track the craniocaudal displacement of the diaphragm during respiratory cycle. Data obtained will contribute to the evaluation of the reliability of diaphragm thickness and excursion measurements for potential future clinical applications.
