Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Non-invasive transcranial magnetic stimulation will be delivered in a protocol called theta burst stimulation. This protocol involves a 2 second train of low intensity stimuli, repeated every 10 seconds for 192 seconds (600 stimuli in total). This protocol will be delivered prior to an upper limb physiotherapy session, 5 days per week for 2 weeks. Each physiotherapy session will be one-on-one with a registered physiotherapist, last approximately 45 minutes, and will be tailored to the individual's needs and goals.

Comparator / control treatment
Sham theta burst stimulation of ipsilesional primary motor cortex prior to each therapy session. A special 'sham' stimulation coil is used, which makes the same sound but does not produce any magnetic stimulation.
Control group
Placebo

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)
Participants will be enrolled by the lead investigator, and their details passed to an associate investigator who will be responsible for randomising them using a minimisation procedure described below. The associate investigator will be responsible for delivering the theta burst stimulation (TBS) intervention, and is the only person who will know which intervention (treatment or control) they are delivering. Participants and all other investigators will remain blinded to allocation, and allocation is concealed from all other investigators.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomised using custom software to minimise differences between the treatment and control groups in age, time since stroke, and corticospinal tract integrity.
Masking / blinding
Blinded (masking used)
