Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: In addition to the control treatment, people allocated to intervention will also receive verbal exercise counselling and support from a physiotherapist over the phone, supplemented by written information about arthritis and the importance of exercise, exercise instructions, links to video clips and/or referral to community exercise services/facilities. Resources will be provided in hard copy via the post. Access to exercise video clips and exercise instructions will be provided via the internet, using the study website. Five to ten telephone calls (45 min duration for initial call, 20 min duration per subsequent call) will be provided over 6 months. Calls will occur in weeks 2, 4, 8, 13 & 21 of the 26 week intervention period. The physiotherapist will use as few or as many of the five additional phone calls as they deem appropriate per individual participant and will schedule these at a mutually agreed upon time. Together with the participant, the physiotherapist will devise a specific strengthening program, as well as a plan to increase general physical activity levels. The content and intensity of the strengthening exercise program will be determined by the physiotherapist in discussion with the participant. In subsequent calls, the physiotherapist will monitor progress, adjust the program and goals and provide support by increasing participant knowledge and understanding, motivation, confidence and self-efficacy for exercise. Physiotherapist will be trained in, and will use best practice principles for supporting behaviour change, when delivering the intervention. Adherence to the intervention will be monitored by a) recording the number of telephone calls the participant participated in; b) asking participants to self-rate their overall adherence to both the strengthening exercises and the general physical activity plan at 6 and 12 month follow up and; c) asking participants to record their use of community exercise facilities/services.

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)
The person who will determine if a potential participant is eligible for inclusion in the trial will be unaware, when this decision is made, to which group the participant will be allocated. Another researcher will access the randomisation schedule which will be concealed in a password protected database.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be by random permuted blocks and stratified by gender. Participants allocated to the intervention group will also be randomly allocated to one of eight trial physiotherapists.
Masking / blinding

Type of endpoint/s
Efficacy
Statistical methods / analysis
Primary endpoints are changes in pain and function at 6 months. There may be clustering effects due to people treated by the same therapist. We assume the eight therapists will treat the same number of people and an intra-cluster correlation of 0.05. We also assume a between-participant SD of 2.2 for pain and 11.6 for function, and a baseline to 6-month correlation in scores of 0.29 and 0.51 respectively. We wish to detect an effect size of 0.5. These assumptions, together with ANCOVA adjusted for baseline scores and clustering, require 70 people per arm for pain and 54 per arm for function with 80% power. Allowing for 20% attrition, we will recruit 175 people. Comparative analyses between groups will use intention-to-treat. Multiple imputation will be used to account for missing data. For continuous data, differences in mean change will be compared with linear regression random effects modelling adjusted for baseline and physiotherapist clustering. For binary and ordinal outcomes, random effects logistic and proportional odds models will be used, respectively.
