My response will be very similar to my reply with the rotator cuff query. 🙂
The great thing about RevInMo is that we have a framework where we can objectively work with someone based on their movement and function rather than a medical diagnosis. Sure, they might have sciatica, but it can arise from a number of things.
Without knowing or seeing this person, my fallback is always going to be:
– How do they move?
– In what exercises do they move well, and why?
– In what exercises are they restricted, and why?
– How do they respond to movement?
For more of a cookie-cutter approach, identify which Essential is most needed, have them perform that Essential-based sequence every day for 2 weeks, and then reassess. Perhaps one of the Pelvic Floor Sequences and add in the Slant Board Series somewhere in there.
