Functional limitation or loss for VA purposes is simply what you can and cannot do as a result of your injuries. You should be as specific as possible when answering questions about your VA functional loss or limitation in your C&P exam or personal statement with examples such as cannot pick up my child; cannot ride a bike; cannot lift, squat,
or drive a car. The following are common examples of functional limitations for joint conditions:
Activities in daily living (severe cases)
Additional limitations due to side effects of medications
Unable to drive a vehicle for long periods
Be sure to list these and explain them on your VA documents and statements such as the QTC questionnaires or DBQs in order to get higher ratings. The more explanation, the better.
