In a previous role, I led a research project focused on evaluating the effectiveness of a new physical therapy protocol for patients with chronic lower back pain. We conducted a randomized controlled trial involving 100 participants. The results showed a significant reduction in pain and improved functional mobility in the intervention group compared to the control group. This study contributed to the evidence base supporting the use of this protocol in clinical practice.

I prioritize ethical integrity by adhering to all relevant guidelines and regulations, such as those set by the Institutional Review Board (IRB). I ensure informed consent is obtained from all participants, maintain confidentiality, and avoid any potential conflicts of interest. Regular communication with the IRB and transparent reporting of study methods and results are also key practices I follow.

Effective recruitment strategies include leveraging community partnerships, utilizing social media, and offering incentives such as gift cards or participation in a raffle. To retain participants, I maintain clear and consistent communication, provide regular updates on the study progress, and ensure participants feel valued and informed about their role in the research. Personalized follow-ups and addressing any concerns promptly also help in retaining participants.

I use validated tools and standardized protocols for data collection to ensure accuracy and reliability. Data is entered into secure databases and regularly backed up. For analysis, I employ statistical software such as SPSS or R, following a pre-defined analysis plan. I also conduct regular quality checks to identify and correct any discrepancies, ensuring the integrity and validity of the data.

During a study on post-operative rehabilitation, we encountered a higher-than-expected dropout rate due to patient complications. To adapt, we revised our recruitment criteria to include only patients with a lower risk of complications and increased our follow-up frequency. We also provided additional support resources to participants. These changes helped us maintain the study's integrity and achieve our research objectives.
