Yes, it is possible to gain range of motion for up to a year after the injury. The largest gains will be seen in the first three months, but with proper use of your splint and a well-guided stretching program supervised by a physical or occupational therapist, you will continue to progress. You can discuss with your physician or therapist the best protocol to use at this point in your rehabilitation. There are many choices that vary in the length of time you wear your splint and the extent of the stretch force applied.
