"Your double-blind RCT needs feminism": an argument for engaging critical theory in quantitative rehabilitation research.

Equitable and inclusive rehabilitation research requires the researcher to consider variables which are neglected in the positivist paradigm. We argue that critical theory can equip researchers with a lens to better address injustices within rehabilitation research. We provide a series of recommendations for researchers to engage critical theory at each stage of the PICO model of clinical trials.IMPLICATIONS FOR REHABILITATIONCommon assumptions in quantitative rehabilitation research (i.e., positivism) can limit the utility of research findings to rehabilitation patients.Equitable, diverse, and inclusive participant samples in research better reflect the diversity of real world rehabilitation patients, helping us better serve these populations.Critical theory can help researchers and clinicians identify and avoid interventions that may cause harm to rehabilitation patients.Research and practice that prioritize concepts of "normalcy" (i.e., "normal gait," "normal behaviours") may perpetuate negative concepts of disability and further marginalize the individuals that our interventions aim to serve.
