Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be screened via telephone during their initial telephone call to determine eligibility. All screening questionnaires are listed in a booklet separate to the assessment booklet.

If the volunteer is determined to be eligible for the study, they will be asked to attend an initial group session where they and 7 others will fill out the baseline assessment booklet. Upon completion of the assessment booklet they will be assigned a sealed opaque envelope from a randomly generated sequence that contains the treatment code and allocates them to either receive the tai chi intervention or continue with their usual care and join the wait-list control.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The allocation sequence will be generated using the random number function in excel. The treatment codes will be placed in consecutively numbered sealed opaque envelopes. Participants will be allocated to treatment by selecting the next envelope in sequence.
Masking / blinding
