Translational Neurorehabilitation Research in the Third World
What Barriers to Trial Participation Can Teach Us?
Background and Purpose—Most stroke rehabilitation studies have been performed in high-income countries. The aim of this study was to identify the main barriers for patient inclusion in a research protocol performed in Brazil.
Methods—We evaluated reasons for exclusion of patients in a pilot, randomized, double-blinded clinical trial of stroke rehabilitation. Descriptive statistical analysis was performed.
Results—Only 5.6% of 571 screened patients were included. Recurrent stroke was responsible for exclusion of 45.4% of potentially eligible patients.
Conclusions—Recurrent stroke represented a big barrier to enroll patients in the protocol. External validity of rehabilitation trials will benefit from definition of study criteria according to regional characteristics of patients, including rates of recurrent stroke.
