The wall hamstring stretch for sciatica relief is most appropriate for those who are not experiencing other acute pain. This video illustrates the steps and modifications for the wall hamstring stretch.
This is the wall hamstring stretch.
This is an advanced stretch good for pain or injury. This is best for the end phases of healing and physical therapy and is not suitable for those in acute pain.
You are gonna begin by lying down on your back with one leg straight up against a wall or a couch. Your stabilizing leg can be bent or if its comfortable, begin to straighten that leg.
Now if achieving this stretch is difficult you can start with a microbend in your leg and slowly work your way into straightening your leg.
You can also begin with your seat further away from the wall, resting your leg at a height that's comfortable for you. And once that becomes easier for you, you can slowly move your seat closer to the wall.
