Description of intervention(s) / exposure
Intervention: Muscle Energy Technique

Muscle Energy Technique is a gentle manual therapy technique used by manual therapists (osteopaths, physiotherapists, chiropractors, myotherapists) around the world. The goal of the technique is to lengthen hypertonic muscles and improve range of motion of joints in the body.

Essential elements of the manual technique involve the following steps:
- Practitioner puts the muscle to be treated on stretch
- Patient is instructed to contract the specific muscle in a specific direction for 3-5 seconds
- Practitioner resists the movement in a controlled fashion for 3-5 seconds
- Patient is instructed to stop contracting the muscle. In this period the practitioner further stretches the muscle slowly to a new resting length
- Repeat this muscle contraction 3-5 times.

The positions that the participant may be positioned in- supine, prone, sidelying, seated. The regions that will be treated include: neck, back (upper and lower), rib cage and associated muscles.

Materials provided to patients: Participants may be shown an A4 page of images depicting the types of positions that the participant may be asked to be in and the type of application of technique. The materials can be accessed from the researcher and intervention provider.

The intervention provider is a registered Osteopath with Australian Healthcare Practitioner Regulation Agency (AHPRA).

Mode of delivery- 'hands on' from the intervention provider. The intervention is provided to the individual participant for up to 15 minutes prior to the Pulmonary Rehabilitation session.

The location of the intervention sessions will be at he Austin Hospital in the physiotherapy department. The intervention will be applied in a private room next to the exercise room. In the room is a hospital bed that can be moved electronically.

The intervention is applied concurrently with Pulmonary Rehabilitation, over 8 weeks. The intervention is applied prior to the exercise session for up to 15 minutes (maximum) in week 1,2,3,5,6 and 7 (total of 6 intervention sessions over the 8 week program). There is no intervention applied in week 4 and 8. The frequency of the application of the intervention is once per week for up to 15 minutes. This is one-on-one with the person administering the intervention. The person administering the intervention is an AHPRA registered osteopath.

The intervention is semi-standardised. This means that each individual participant is assessed in the same regions (i.e neck left/ right, upper and lower back left/ right) and then the intervention is applied tailored to the individual findings. Individual findings will not change the type of intervention applied. It will only change the regions treated. For example, if the findings require the positioning of the upper extremity in a certain position, but the individual is unable to lift their arm to the required position, the intervention is able to be modified in terms of treating another region, or in another position. Individual findings also means that treatment (intervention) is applied to a finding, and regions are not treated unnecessarily.

The intervention has not currently been modified during the study. No intervention adherence or fidelity was assessed as there have been no modifications.

Strategies used to monitor participant adherence include an individualised session attendance check list given to the participant at baseline; where the dates of intervention have been negotiated and discussed between the researcher and the individual, and written on the checklist for the individual to take home.

Outcomes
Primary outcome [1] 305028 0
The primary outcome of the trial is feasibility. This will be assessed via a phone call conversation at week 12 (four weeks after completion of the exercise program) by one of the research team who has had no contact with the individual. Feasibility will be assessed by asking participants questions relating to the acceptability of the intervention and implementation of a manual technique protocol within an established pulmonary rehabilitation program. This is a composite outcome, The addition of focus groups at the completion of the trial is the other way we will capture feasibility of the intervention in terms of acceptability of intervention (by participants) and implementation of the intervention (from a participant and staff viewpoint). Focus groups will be conducted with the participants and the staff members who have been involved in the trial. There will be three focus groups for participants, and one focus group for physiotherapy department staff who are involved in the trial. A written feedback schedule was also added to capture any staff members who were unable to attend the staff focus groups.
Timepoint [1] 305028 0
Participants will still receive a phone call at week 12 (12 weeks post commencement of the intervention).

The focus groups will be conducted after the trial is completed for the participants and after data collection is completed with staff.

Statistical methods / analysis
The number of participants required is based on convenience sampling at the site, after considering the number of potentially eligible participants. The local site PR program assesses approximately 200 new patients annually, 50 per cent of whom have a diagnosis of COPD. There is an expected attrition rate of 20 per cent based on experience from previous PR studies at the hospital.

We anticipated that approximately 20 per cent of people undertaking PR would be eligible and consent to participate in this feasibility study and expected an attrition rate of approximately 20 per cent. Based on the available data, a convenience sample size of 26 participants was calculated to be recruited in one year (full-time recruitment). Allowing for a 20 per cent attrition rate and no replacement of dropouts, a sample size of 33 participants was determined, all of whom were allocated to a single intervention group.

Statistical methods involve: Characteristics of participants, feasibility outcomes of acceptability and safety in terms of adverse events will be calculated using descriptive statistics. Analysis of outcome data from baseline, mid-treatment, end of treatment and follow up will be made using within-person analysis over the time points

Assumptions for normality will be checked prior to analysis. Both per-protocol (PP) and intention-to-treat (ITT) analyses will be performed. For ITT analysis, multiple imputation method is used for missing data. All variables from Week 0 and Week 12 were included in the imputation model. There will be 20 imputations performed. Multiple imputation pattern analysis will be conducted to evaluate for monotonicity and to identify any random pattern to the missing data.

Paired t-tests will be used to compare normally distributed data for outcomes measured at Weeks 0 and 8, Weeks 0 and 12, and Weeks 8 and 12. Non-normally distributed data will be evaluated at those same time points using a Wilcoxon signed-rank test.

A one-way repeated measure (ANOVA) will be used to assess any differences over the three time points of Weeks 0, 8 and 12 for inspiratory capacity (IC) and HRQoL questionnaires (CAT questionnaire and CRQ-SAI). A PP analysis was conducted for these measures. An additional ITT analysis will be conducted for IC because it was measured both pre- and post-MET sessions across the duration of PR, and it directly relates to one of the research questions regarding changes in IC.

Effect size for a future larger RCT will be calculated using Cohen’s d effect size utilising IC. Sample size will be estimated for a power set to 80%, and significance level of 0.05.
