Plain English Summary
Background and study aims
Having an acquired brain injury (stroke or traumatic) often results in difficulty with completing everyday tasks due to people having a decreased ability to use their arm effectively. This may often lead to a decreased quality of life and decreased independence in everyday activities. The aim of this study is to investigate how easy/difficult a therapy called Constraint Induced Movement Therapy (CIMT) is to deliver to patients and also to indicate if any improvements in their upper limb use occurs after using this therapy. It is hoped that this information will provide a better understanding of the therapy and show what further research is needed to be completed on the therapy.
Who can participate?
Both male and female patients, currently attending the Regional Acquired Brain Injury Unit (RABIU) in Musgrave Park Hospital are eligible to attend, providing they meet baseline arm movement requirements and upper limb treatment is a main therapy goal for the patient.
What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 (experimental) are given CIMT for one and a half hours a day, 5 days per week for 3 weeks. Those in group 2 (control) are given standard (Bobath based) therapy over the same time period. Arm function, psychological effects (for example, improvements in depression or anxiety) and adherence to the treatment are assessed for all participants before their treatment starts, on the last day of treatment and then 12 weeks later.
What are the possible benefits and risks of participating?
There are both potential benefits and risks of taking part in the study including improvement in the amount and quality of movement in the patients’ arm. One potential risk is an increase in the amount of pain due to overuse of the arm; this will however be closely monitored by the therapy team and the therapy will be stopped or adapted if this occurs.
Where is the study run from?
Regional Acquired Brain Injury Unit -Belfast Health and Social Care Trust (UK)

Constraint Induced Movement Therapy (CIMT) for acquired brain injury: a clinical feasibility RCT investigating CIMT versus a Bobath based upper limb intervention.
Despite its robust evidence, gaps remain within CIMT research. The majority of studies have been completed in controlled laboratory settings in the United States of America and clinical settings in Asian countries such as China, Thailand and Taiwan; both of which are not directly comparable to the United Kingdom (UK) National Health Service (NHS). Although similarities could be drawn between the clinical settings of the UK and Asia, many differences exist such as the higher level of private healthcare in Asia (WHO 2009). To our knowledge there has only been one registered CIMT trial within the UK which is currently exploring web based CIMT (LifeCIT: NCT01350453); none have been completed in the UK clinical setting. In addition there have been no trials reporting the use of a multi disciplinary therapy team (both physiotherapists and occupational therapists) to deliver CIMT as well as very few trials investigating CIMT with the traumatic brain injury (TBI) population; the majority of research to date has focused on the stroke population. The aim of this current study was to address these research gaps and apply CIMT in the UK NHS clinical setting with both the stroke and traumatic brain injury population.
