Description of intervention(s) / exposure
Participants were blinded and randomly assigned into one of two interventions, either a ‘yoga inclusive management program’ - Group A or an ‘active control standard care program’ - Group B. All participants were offered Standard self-care management for myofascial pain. This was done by a discussion on self-care management strategies and by providing an email copy of ‘Immediate management of Temporomandibular disorders’ document (Table 1).
Participants in Group A were provided a yoga mat and taught in groups (no more than 5) simple yoga activities to be performed daily for 30 minutes. The group then demonstrated to the instructor standardised activities which included 15 minutes of active physical yoga exercises, 15 minutes of breathing exercises and meditation. The activities included an initial warm-up exercise; a short sequence of 9 to 12 movements (sun salutation); 4 sustained yoga postures; breathing exercises; and a brief period of focused attention. A summary of exercise routines for each yoga session is presented in tables 2, 3 and 4. Further details and particulars of the yoga exercises are presented in appendix 1. Yoga sessions were conducted by a trained yoga instructor (with minimum 3 years’ experience) in a lecture room at 3 locations in Sydney: at the Westmead Centre for Oral Health (WCOH), at the Sydney Dental Hospital (SDH), and at The University of Sydney Camperdown Campus (USYD). Each participant was seen twice weekly by a researcher for 30 minutes and were instructed and reviewed on the daily activities. Participant adherence with the treatment was assessed with a self-report daily diary (appendix 3). Participants were emailed a copy of the session routines outlining the sequence of yoga exercises after they attended the sessions for weeks 1, 2, 3 and 4. This was done to assist them in practicing the yoga exercise at home. The total duration of this yoga intervention was 28 days.

Comparator / control treatment
The comparator group in our study was an ‘active control standard care program’ - Group B. Group B participants were provided with an un-heated heat pack (Head and Neck terry towel, Chattanooga group Inc., NSW, Australia) and a pedometer (SW 200 Yamax, YAMASA TOKEI KEIKI CO., LTD. Tokyo, Japan). They were instructed on the use and functions of the pedometer and on completing a daily walking task in an unobstructed and clean space for 15 minutes and on the application of the un-heated heat pack to the neck and masticatory muscles for 15 minutes. Participants then demonstrated these activities correctly. This sham treatment was to reduce the effect of differences in appointment duration and instructors interaction between the two groups.
These sessions were conducted by a researcher and administered as a group session (group of no more than 5 participants) at 3 locations in Sydney: at the Westmead Centre for Oral Health (WCOH), at the Sydney Dental Hospital (SDH), and at The University of Sydney Camperdown campus (USYD). Walking sessions was performed in an open space and application of unheated heat pack in a lecture room at the above locations. Each participant was seen twice weekly by a researcher for 30 minutes and were instructed and reviewed on the daily activities. Participant adherence with the treatment was assessed with a self-report daily diary. Participants were emailed a copy of the session routines outlining the sequence of walking exercises after they attended the sessions (table 5). This was done to assist them in practicing the active control program at home. The comparator group performed their program for the total duration of the study i.e. 28 days.

Other design features
Blinding was preserved from allocation concealment until the first activity (yoga/active control) session. Keeping the study participants unaware of the assigned intervention until the end of the study could not be successfully implemented in the yoga group. It is to be noted that participants in Group A were unaware of the activities in Group B and vice versa.

Statistical methods / analysis
For the outcome criteria, per protocol approach was used. Age, gender and all other outcome measures were analysed using Independent t-test or Mann Whitney test for continuous variables and chi square test for categorical variables to assess the similarities and differences between the two intervention groups at baseline.
Calculating assessment values for primary and secondary outcomes: The change in each outcome measure, except the clinical parameters, between the baseline and day 14 and between baseline and at the end of the study were calculated. The change in clinical parameters between beginning and end of the study were calculated.
To determine the effectiveness of intervention, individual changes were calculated, and the group means of the changes were analysed using the Mann Whitney test for all jaw muscle pain outcome measures. All data were expressed as mean, median, Standard Deviation and percentiles (25,75). Statistical analyses were conducted using SPSS for Windows (version 19: SPSS Inc, Chicago, Illinois, USA).
For the post study feedback, descriptive statistics were used and p values were calculated from independent t test.

Summary
Brief summary
Background & Aim:
Myofascial pain or jaw muscle pain is a common orofacial pain resulting in impairment of jaw function, and high health-care costs. It is most common in the 20–40-year age range. The aim of this study is to evaluate the feasibility, acceptability, and effectiveness of yoga in adult students experiencing myofascial pain.
Methods:
Subjects were recruited from a university student population and invited to learn more about the study through advertisements by email. Those interested were provided a jaw health screening questionnaire and if self-reporting facial pain they were invited for clinical examination to confirm orofacial myofascial pain (using standardised Research diagnostic criteria for Temporomandibular disorders [RDC/TMD]). 25 students with diagnoses of myofascial pain volunteered for this double-blind randomized controlled study. Participants undergoing other management for facial pain and TMDs were excluded. Participants were randomized to one of two interventions, either a yoga inclusive management programme or an active control standard care programme. Both groups received the intervention for 28 days. The outcome measures analysed were the change in pain intensity on an 11-point numerical rating scale and change in pain location and distribution using digitalized pain mapping software. Jaw mobility, oral health related quality of life and cognitive factors related to the participant’s understanding of pain were determined at baseline, at 14 days and at the end of 28 days. Change in outcome measures between baseline and (outcome points) were analyzed using Mann- Whitney test.
Hypothesis
That there will be a statistically significant difference in the treatment benefits between a yoga exercise inclusive management program as compared to active control standard care for the management of jaw muscle pain.
