Description of intervention(s) / exposure
Exercise Programme:
Participants randomized to the exercise programme will visit the Massey University recreation centre, twice a week, for 8 weeks to take part in a group focused exercise session. Each exercise session will last 90 mins, incorporating 30 mins of aerobic exercise (treadmill, cycle ergometer) and 60 mins of balance based exercises. The balance exercises will include resistance exercise, core-stability, control, postural exerices, flexibility etc. Participant’s progression will be monitored over the course of the programme. Heart rate, blood pressure and perceived exertion will be monitored at rest, during the session and following the session. The group exercises will be supervised by the principal investigator (lecturer in exercise prescription and 8 years expereince of working with patient populations) and postgraduate MSc research scholars who have more than three years of practical experience of working with patient populations.

Comparator / control treatment
The control condition will complete identical assessment procedures as those randomized to the exercise programme. However, those randomized to the control condition at the completion of the baseline assessment will receive normal care during the 8 week exercise programme. No additional supportive strategies are implemented in the 8 weeks following the TIA for those randomized to the normal care condition. As such, normal care enables patients to visit their general practitioner, physiotherapists and hospital (i.e., for check-ups) as and when the patient feels that it is needed or requested.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The Stroke Department at Wellington Hospital receives referrals for all those with possible TIA in the Region. Referrals are received via telephone, fax or e-mail from General Practitioners, the Emergency Department and Paramedics. All referrals are reviewed within 2 working days by a specialist physician and appropriate diagnostic tests undertaken, as per the NZ TIA guidelines. Between 6 and 10 referrals are seen each week. Those in whom a diagnosis of TIA/Non-disabling stroke is reached will be invited to participate. Following the baseline assessments participants will be randomized to the exercise programme or to the control group. Randomization will the occur via 'allocation concealment'. Allocation concealment will occur via sealed opaque envelopes which will be sequentially numbered.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computerised sequence generation The randomization sequence will be generated using the following internet source (http://www.randomizer.org/form.htm). The randomization sequence (i.e. A = Exercise; B = Control) will be placed in a sequentially numbered envelope (from 1-30) based on the derived sequence generated by the website

Summary
Brief summary
Recent research has demonstrated that balance and balance confidence is impaired after stroke, limiting independence in activities of daily living (i.e., cooking, shopping, walking, etc). When symptoms of stroke resolve within 24 hours it is known as a Transient Ischaemic Attack (TIA; ‘mini’ stroke). To date, research is yet to identify whether balance and/or balance confidence is impaired in patients following a TIA. Anecdotal evidence from the study CEN/10/10/046 revealed that balance may be impaired in TIA patients. TIA patients mentioned that they received substantial functional benefits from exercises aimed at improving balance after completing an 8 week exercise intervention. However, the degree to which a balance-based exercise intervention positively influences balance performance and confidence has not been established. Therefore, the purpose of this investigation is to identify whether balance is actually impaired in TIA patients. Previous research has demonstrated that balance training exercises improves balance performance and confidence after stroke. Providing balance impairments are found in TIA patients, this investigation also aims to identify the effects of a balance-based exercise intervention on balance performance and confidence.
