With hip dysplasia, you are probably going to have a big focus on strength/reactivation/coordination to maintain hip joint integrity.
There are no exercises when done carefully and mindfully are inherently dangerous. We have had other people use the program with hip dysplasia who never encountered any problems. With that said, any exercise can be done 1) too fast 2) with excessive force 3) beyond one’s current comfortable range of motion.
Do your best to be conservative and patient. Comfort is the goal.
Focus on creating strength and stability around the hip joint. Stretching should be slow and gentle, never forcing end ranges or stretching through painful / pinching feelings. If pinching is experienced, practice a gentle contraction of the targeted muscles to help re-center the hip and create more stability.
Many people with the dysplasia diagnosis tend to be hyperflexible in the hips. If that is the case, you will want to focus on the strengthening /re-education portion of the program and spend comparatively little time on the stretching and tissue work.
