About this study

Official title: Investigating the Effects of Soft Tissue Mobilization on Respiratory Muscle Function and Playing Performance in Trumpet Players

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.

Read the detailed description

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.

  4. Peak Expiratory Flow (PEF)

    PEF in liters per second (L/s), measured with a CHEST HI-801 spirometer.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

  5. Maximal Voluntary Ventilation (MVV)

    MVV in liters per minute (L/min), measured with a CHEST HI-801 spirometer.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

  6. Resting Tidal Volume

    Tidal volume during quiet breathing in liters (L), measured with a CHEST HI-801 spirometer.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

  7. Resting Respiratory Rate

    Respiratory rate during quiet breathing in breaths per minute, measured with a CHEST HI-801 spirometer.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

  8. Ventilatory Reserve

    Ventilatory reserve in percent (%), calculated by the CHEST HI-801 spirometer from resting minute ventilation relative to MVV.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

Secondary outcomes (8)

  1. Standard Deviation of Fundamental Frequency During Sustained Note

    Standard deviation of the fundamental frequency in hertz (Hz) during a sustained G4 note, extracted with automated pYIN-based acoustic analysis.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

  2. Mean Fundamental Frequency During Sustained Note

    Mean fundamental frequency in hertz (Hz) during a sustained G4 note, extracted with automated pYIN-based acoustic analysis.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

  3. Lowest Attainable Pitch

    Lowest fundamental frequency in hertz (Hz) reached during a descending pitch-range task.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

  4. Maximal loudness

    Peak sound level in decibels relative to full scale (dBFS) during a G major arpeggio played at maximal controllable loudness.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

  5. Highest Attainable Pitch (Hz)

    Highest fundamental frequency in hertz (Hz) reached during an ascending pitch-range task.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

  6. Highest Attainable Pitch (MIDI Semitones)

    Highest pitch reached during the ascending pitch-range task, converted to MIDI semitone units.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

  7. Rating of perceived exertion

    Rating of perceived exertion on the Borg 6-20 scale (minimum 6, maximum 20; higher scores indicate greater perceived exertion, i.e., a worse outcome), rated immediately after a high-register melody task.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

  8. Sustained-note duration

    Duration in seconds (s) of a sustained G4 note played as long as possible.

    Measured: Baseline (immediately before) and immediately after the single intervention session (same day)

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Forced Vital Capacity (FVC) (time frame: Baseline (immediately before) and immediately after the single intervention session (same day)). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07904858.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
