Acquired brain injury (ABI) presents unique challenges that make rehabilitation difficult to standardize. The development of best-practice principles has been hindered by limited access to adequate sample sizes and appropriate comparison groups in patients with ABI within a clinical, rehabilitation environment (National Institute of Health 1998). Further, there remains a need for more prospective studies, and a more uniform approach to standardized assessment and outcome measures (New Zealand Guidelines Group 2006). As a result, a consensus on optimal models of care for patients with ABI has been elusive.
