She sounds more like a chiropractor. Perhaps this calls for a new thread.
Not so much a chiropractor as a remedial masseur or therapist. These are sort of extreme sports masseurs and fill the gap between physiotherapy and normal sports massage. I go from time to time to a Dutch guy who has a practice in Kendal and it's not for the faint hearted.
One particular issue was 'over-developed hip flexors' from 'bent riding which manifest as tight hip joints and a rather unfortunate tendency to exacerbate my back problems. A sports massage wouldn't really do much for hip flexors as they're deep muscles and a bit tricky to massage directly. But stretching is another matter and the remedial masseur, after a thorough warm up, usually stretches the muscles through an almost unbelievable range (I am naturally hyper mobile, given to doing the splits and walking about in 'the crab' - upward bow, if you do yoga - as a youngster) with my feet ending up behind my head. It's not entirely painless as anyone who practices deep stretching will know - there's a fine line between getting the maximum benefit and hurting yourself. But the results are immediate and long-lasting.
I tend to think remedial therapists like this are very under-used in this country where 'massage' is usually a pathetically gentle stroking with nice smelling oil and candles lit about the room for relaxation, and practiced by beauticians with a very inadequate knowledge of physiology. Having trained as a sports masseur and practiced in the past, I know what sports and remedial masseurs should know and be able to do and, if you haven't actually got an injury but a chronic problem which could result in one, they're the best place to go - usually a good deal cheaper than a fully fledged physio.
