Interventional
Description of intervention(s) / exposure
Circadin melatonin 2mg prolonged release tablet is be taken orally after food and 1-2 hours prior to going to bed.

Comparator / control treatment
The control formulation matched active treatment for appearance and size consisting of Mannitol (106mg), Acacia (11mg) and Pure icing sugar (106mg). Both treatments were encapsulated in identical two-piece gelatin capsules and dispensed in identical containers, containing 30 capsules.

Outcomes
Primary outcome [1] 268985 0
Sleep onset latency
Timepoint [1] 268985 0
Mean sleep onset latency (minutes) will be measured continuously throughout the trial and over the 10 week period via Actigraphy. Sleep onset latency will be averaged over the baseline period and after each intervention period, respectively.
Primary outcome [2] 297319 0
Sleep quality: Sleep quality will be determined by global scores from the Pittsburgh sleep quality index (PSQI) questionnaire. The PSQI requires participants to subjectively rate their sleep quality in the previous month and will be used to determine treatment efficacy.
Timepoint [2] 297319 0
Sleep quality will be assessed pre and post baseline, and at the end of each treatment period. Consistent with other measures, sleep quality will be first assessed at baseline (week 0). The second takes place at the end of the baseline run-in period (week 2). The third at the end of treatment one (Week 6). The fourth at the end of treatment two (week 10).
Secondary outcome [1] 276753 0
Depression and Anxiety will be assessed with the use of paper and pen Hospital Anxiety and Depression Scale (HADS).
Timepoint [1] 276753 0
Depression and Anxiety will be assessed at four time points. The first takes place on their baseline assessment (week 0). The second takes place at the end of the baseline run-in period (week 2). The third at the end of treatment one (Week 6). The fourth at the end of treatment two (week 10).
Secondary outcome [2] 276754 0
General health and well being will be assessed with the use of a papper and pen questionnaire namely the SF-36 Health Related Quality of Life Questionnaire (SF-36).
Timepoint [2] 276754 0
General health and Well being will be assessed at four time points. The first takes place on their baseline assessment (week 0). The second takes place at the end of the baseline run-in period (week 2). The third at the end of treatment one (Week 6). The fourth at the end of treatment two (week 10).
Secondary outcome [3] 320715 0
Mean sleep efficiency (%) determined by actigraphy.

Daytime sleepiness as measured by the Epworth Sleepiness Scale (ESS)
Timepoint [4] 320716 0
ESS scores will be collected pre and post baseline and at the end of each treatment intervention, respectively. Consistent with other measures, ESS scores will be first assessed at baseline (week 0).

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Rehabilitation physicians and allied health staff will be responsible for approaching and informing ABI participants with sleep disturbance of the study. All participants will need to seek approval from their treating rehabilitation physician in order to participate in the study. Suitable candidates will be referred to a research assistance to determine study eligibility. Individuals meeting preliminary eligibility will be referred for a sleep physician consultation to further determine eligibility. Individuals meeting eligibility criteria will be encouraged to discuss participation with family, friends and other doctors not involved in the study before consenting.
The rehabilitation physician will be responsible for writing the treatment scripts (i.e., melatonin and placebo), but is blinded to treatment. Treatment randomization will be computer generated and recorded by the pharmacist not involved or associated with the study, with randomization sealed in opaque envelopes. Each envelope will indicate the order of treatment and the pharmacist not associated with the study will allocate treatment accordingly.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization was conducted by a researcher independent of the study, not involved with recruitment, testing or analysis. Block randomization was used (block size of 4) and six possible balanced permutations for assignment to the two conditions were each assigned an integer from one to six. Treatment conditions were assigned and sealed in an envelope ("M" for Melatonin first and "P" Placebo first). Participant codes were sequentially allocated as participants enrolled and treatments were dispensed by a pharmacist not affiliated with the study. Participants were randomized to receive melatonin or placebo treatment first at the end of the baseline period.

Summary
Brief summary
Sleep disturbance occurs in a significant proportion of the Acquired Brain Injury (ABI) population. Traumatic Brain Injury, a type of ABI, has been associated with reduced sleep quality, more night-time awakenings and longer sleep onset latency's. Recent research has shown that TBI patients have significantly lower endogenous concentrations of melatonin in the evening as compared to healthy controls. Melatonin is a naturally occurring hormone in the body which is intricately involved in the regulation of sleep and more importantly with the timing of sleep. Specifically, recent work has shown that this reduced concentration of melatonin was related to reduced rapid eye movement sleep and that these patients had more arousals during the evening. In light of recent work which provides evidence that a prolonged release melatonin formula is efficacious in treating age-related insomnia in individuals who also have decreased bodily concentrations of melatonin, it is hypothesized that melatonin will reduce the time taken to sleep and will improve sleep quality in ABI patients. The current study will implement a randomized, placebo-controlled crossover study with the aim of recruiting 80 participants. ABI patients who report sleep disturbance post injury will be eligible to participate. As this is a crossover design every participant will receive both the placebo and active melatonin treatments. If melatonin therapy is successful in reducing latency to sleep and improved sleep quality this could substantially improve the quality of life of individuals with ABI. As melatonin is a naturally occurring hormone relatively devoid of side-effects, its use to treat sleep disturbance could be implemented into clinical practice.
