Background: Sample size calculations are performed to ensure sufficient power, which reduces the probability of Type II error. Therefore, performing these calculations can help ensure that the findings obtained are both reliable and meaningful. Our objective was to review the reporting of sample size calculations among randomized controlled trials (RCTs) evaluating motor function post stroke. Methods: A comprehensive literature search until the end of 2016 was conducted with the following inclusion criteria: RCT study design, stroke population of u226550%, participants of u226518 years of age, with participants receiving an intervention targeting motor function. Studies of safety and feasibility were excluded. Sample size data and its calculation were extracted. Methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) tool. Descriptive statistics and t-tests (p
