Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Health coaching via telephone to support a physiotherapist provided physical activity program. The intervention phase will last 6 months.

Health coaching: Three health coaches will provide the telephone coaching for the study. The health coaches will all have a qualification and experience in nursing and will have been trained in health coaching by Health Change Australia. Participants will be called a minimum of 6 times and a maximum of 12 times during the 6-month treatment phase. The health coach will determine how many additional telephone coaching sessions are needed based on the participant’s preferences, their confidence and their success in achieving the desired behaviour changes. The duration of telephone coaching sessions are expected to average around 20 mins with considerable variability. The initial calls are likely to be longer (up to 45 mins) with call duration reducing over the treatment phase.

Physiotherapy: Each participant will visit the physiotherapist five times, and each session will last for 30 minutes. The treatment program will include three components:
1. Structured exercises to address presenting impairments
2. Increasing overall levels of physical activity
3. Information and education

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 they will be allocated. Allocation will be concealed in opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation stratified by physiotherapist. The physiotherapist will be determined according to geographical location.
Masking / blinding
