This single-group pretest-posttest study examined the immediate effects of a single session of integrated soft tissue relaxation, combining instrument-assisted soft tissue mobilization (IASTM) and manual release techniques, on pulmonary function, resting breathing pattern, trumpet-playing acoustic performance, and perceived exertion in experienced trumpet players.
Brass players experience sustained high respiratory and orofacial muscle load. Fifteen healthy adult trumpet players with at least 5 years of playing experience completed baseline assessments, received one 15-20 min session of integrated soft tissue relaxation targeting the perioral, cervicothoracic, intercostal, diaphragmatic, and abdominal regions (IASTM combined with manual release; intensity 3-6 on a 0-10 participant-rated pressure scale), and repeated the same assessments immediately afterwards. Outcomes were forced pulmonary function and resting breathing pattern (CHEST HI-801 spirometer), acoustic features of four standardized playing tasks (automated pYIN-based analysis), and rating of perceived exertion (Borg 6-20).
This study was approved by the Institutional Review Board of Fu Jen Catholic University (C113180) on July 14, 2025, and data collection took place on September 10-17, 2025. The study was registered retrospectively after completion. Maximal inspiratory and expiratory pressures were listed in the approved protocol but could not be measured because the measurement module was unavailable during the data collection period.
National Taipei University of Nursing and Health Sciences is the lead sponsor of 124 studies on the registry; 23 are open to participants now.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

A single 15-20 min session of IASTM combined with manual release applied in a top-to-bottom sequence to the perioral, cervicothoracic, shoulder girdle, intercostal, diaphragmatic, and abdominal regions.
Other: Integrated soft tissue relaxation (IASTM + manual release)
Delivered by one trained practitioner according to a written protocol. Pressure was applied during exhalation and eased during inhalation, with intensity titrated to a participant-reported pressure of 3-6 on a 0-10 scale.
