slump / SLR

I have a patient who is a competitive surf ski paddler. He has had gluteal pain for two weeks. His main problem is neural tension and therefore a positive slump and half SLR. He thus cannot sit properly on the ski as this requires a slump like position. I am basically brainstorming for ways to improve slump / SLR. Anyone got some good ideas

u can try giving stretch to piriformis muscle this may improve the symptom

lengthen gluteals and lumbar extensors. increase internal hip joint rotation and then teach him how to ski proerly. he shouldn't be in a slump position? maybe he needs to move his foot pedals, change his padel length or get a new ski?
