How often should your client fill out the LEFS or UEFI?

The correct answer is that clients should fill out the Lower Extremity Functional Scale (LEFS) or the Upper Extremity Functional Index (UEFI) every 4 weeks. This timeframe is deemed appropriate because it allows for enough time to accurately assess changes in a client’s functional abilities and progress in their corrective exercise program. Monitoring at this interval provides sufficient data points to make informed decisions about necessary adjustments to the program, ensuring it remains effective and aligned with the client's rehabilitation or fitness goals.

Additionally, assessing functionality every 4 weeks strikes a balance, providing a regular check-in without being burdensome or overly frequent. It helps track progress without overwhelming the client with constant assessments, which can lead to "assessment fatigue." Regularly revisiting these scales enables trainers to gather meaningful insights into trends of improvement or stagnation, facilitating timely modifications to the exercise plan.
