Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation involved contacting the holder of the allocation schedule who was not involved in participant recruitment and not in contact with prospective participants.

A block randomisation for 3 arms (Pilates + exercises; yoga + exercises and Exercises only) generated in advance of recruitment for the target sample size, using the website http://www.randomization.org, and held by an investigator not involved in the recruitment process. Upon enrollment, the allocation was requested and emailed to study personnel involved with participants.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation using the website http://www.randomization.org

Statistical methods / analysis
Analysis of Variance for changes in primary and secondary outcomes

Correlational analysis of potentially explanatory variables and primary and secondary outcomes

Calculation of effect size using G*Power 3 (Faul, Erdfelder, Lang & Buchner, 2007) has taken into account a comparison of changes from before to after the intervention using dependent differences tests as well as differences between independent groups. Three previous studies reviewed (Rydeard et al, 2007; Cramer et al, 2013; Ezar et al, 2012) do not show clear differences in effect sizes noted for pain in change from baseline following yoga and Pilates interventions (ES range from 2.8 – 3.6 reductions in pain) compared to differences in changes in pain noted between treatment and exercise control groups (ES range from 1.0 – 2.5 more reduction in intervention compared to control groups). When comparing changes in a treatment versus control group, a sample size of 17 in each group would be required to detect a difference in change between groups of ES = 1 (the smallest effect reported in the above studies), assuming a level of significance of 0.05, and statistical power of 80%. To allow for withdrawal from the study and non-compliance, an initial sample size of 20 per group is sought. A sample of 19 in each intervention group would also provide sufficient power to detect changes from pre- to post-intervention of ES = 0.7 using the above assumptions, much smaller than those effects reported in the above studies.
