Description of intervention(s) / exposure
Chronic Asthma Sufferers who qualified for this study were randomly allocated to three groups, A, B and C. Groups A attended treatment centers and only group A receive 3 spinal manipulative therapy sessions per week for up to 6-weeks, in one of 19 treating centers within NSW. Randomly allocated control participants in group B also attended treating centers and participated in all assessments criteria but did not receive any spinal manipulative therapy for 6-weeks. Assessment included interviews with attending clinician, palpation of the spine (hands on assessment of spinal motion only), completed questionnaires and submitted salivary samples. However, Group C participants provided all salivary samples and questionnaire for the same period of 6-weeks from home.

Spinal manipulative therapy involves the use of hands on techniques to articulate vertebral joints. Specifically this chiropractic technique involved a high velocity low amplitude thrust delivered in a desired direction to restore joint motion. On average a treatment session would be between 15 and 20 minutes.

Outcomes
Primary outcome [1] 2705 0
Changes in baseline cortisol and Immunoglobulin A (IgA) levels were analysed from salivary samples
Timepoint [1] 2705 0
Salivary samples collected on Tuesdays, Thursdays and Sundays at 8AM and 8PM. Salivary samples were collected for 14 weeks from each participant.
Secondary outcome [1] 4564 0
All participants completed a Depression Anxiety Stress Scale (DASS), a wellness questionnaire (SF-36) and an Asthma global questionnaire.
Timepoint [1] 4564 0
These were administered at the beginning of the trial (day1 week 1), at day 1 week 7 and at day 7 week 14.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation was concealed from all decisions as to what group a participant is likely to be in by independently using a central computer based randomisation process.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer based random number generator was used to allocate participants into the three Asthma groups. Participants were allocated into three parallel groups (groups A, B and C). Group A received the treatment while groups B and C acted as controls.
Masking / blinding
Blinded (masking used)

Intervention assignment
Parallel
Other design features
Subjects were instructed that their treatment program will consist of 14 weeks of participation and at various times throughout the fourteen weeks they will receive a variety of manipulative interventions. They were not aware of when they will receive the SMT. Effectively both groups A and B believed that they will receive SMT, however, group A was the only group that did. As such participants were masked. However, the clinicians who delivered the therapy itself were not blinded simply due to the nature of this type hands on of manual therapy, effectively a single blind study design.
