Abstract
The evolution of evidence based practice in health care has produced an emphasis on documenting the effectiveness of interventions used in neurologic rehabilitation. This paper describes the methods of single system designs as one approach to address the demands of evidence based practice. Single system designs include a wide range of strategies that are practice based and practitioner oriented. The designs provide an alternative to traditional experimental approaches requiring the random assignment of a large number of subjects to treatment and no treatment (control) groups. The characteristics of single system designs include the repeated assessment of individualized outcome measures for single patients or small groups of patients treated as a single unit. The designs can be used to monitor patient improvement over time and to demonstrate relationships between intervention and outcome measures for specific patients. Data analysis focuses on the presentation and interpretation of patterns of responses over time. The emphasis in single system data analysis is on the clinical significance of individual change versus the statistical significance of comparisons between groups. The advantages and limitations of single system designs are discussed, and the argument is made that these designs can contribute to the evolving knowledge base in neurologic rehabilitation.
