I've seen Dr Penner for a few years now when my lower back acts up. It used to be incapacitating for days, and now it's just a one day annoyance. His advice on exercises, and his sure hands have made the difference.
One important thing: he is willing to honestly discuss what's just a theory and what's proven, and admits what might not work. Additionally, his explanations of how the body protects old injuries and winds up atrophying the minor muscles makes a lot of sense...and leads to useful exercise regimes.
