Case studies involve utilizing a distinct research approach. They are often confused with case reports, case series, cases used in rounds, and cases without control groups or baseline measures. The case study approach can provide a way to investigate broad chiropractic issues, policies, or practices in their real settings. Case study research designs are appropriate in both clinical and nonclinical settings. They require good conceptual skills not elaborate equipment; extensive “thinking” time but not sophisticated statistical analysis; and, a well-designed case study protocol but no control groups or randomized trials.
