Outcomes
Primary outcome [1] 288123 0
Forced expiratory volume in one second. This will be assessed using a spirometer to measure the volume of air forcibly exhaled in one second.
Timepoint [1] 288123 0
baseline and repeated at 1 minute, 10 minutes, 20 minutes and 30 minutes following the manual therapy
Primary outcome [2] 288124 0
Maximal voluntary ventilation. This will be assessed using a spirometer to measure the volume of air exhaled during repetitive maximal inhalation and exhalation over 15 seconds.
Timepoint [2] 288124 0
baseline and repeated at 1 minute, 10 minutes, 20 minutes and 30 minutes following the manual therapy
Secondary outcome [1] 299458 0
Forced vital capacity. This will be assessed using a spirometer to measure the volume of air that can forcibly exhaled after a maximum inhalation.
Timepoint [1] 299458 0
baseline and repeated at 1 minute, 10 minutes, 20 minutes and 30 minutes following the manual therapy

Study design
Purpose of the study
Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be recruited from advertisement at the the Murdoch University campus.

Individuals interested in study participation will contact one of co-investigators and be scheduled for an appointment. At that time, the potential participants will complete a screening questionnaire to identify their status on all selection criteria. Eligible individuals will be provided with a research ethics information letter and consent form and be provided with the opportunity to have any questions or concerns addressed by a study co-investigator.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Not applicable
Masking / blinding
Open (masking not used)

Intervention assignment
Single group
Other design features
This study will use a pretest-posttest within subjects design involving repeated measures in the post-intervention period. Measures of pulmonary function will be obtained at baseline and repeated at 1 minute, 10 minutes, 20 minutes and 30 minutes following the manual therapy intervention.

Summary
Brief summary
The aim of this study is to examine for differences in pulmonary function before and after the application of manual therapy to the thoracic spine and thorax (i.e., chest wall). We hypothesize that pulmonary function will improve following the application of manual therapy and that the improvement will be sustained throughout the post-intervention period.
