There's a really good PT in McKinney, Jimmy Armentrout, and I think a 5:00 is the last appt he takes. Also James (can't remember his last name) at Allen Sports & Spine in the Raintree building does later appointments. I used to know of a really good PT at Allen PT but she has recently left and haven't heard any good things at all about her replacement. Some also do early morning appts too like at 7. No matter where you decide to go, I would make sure that his PT practices manual therapy. Specifically, that means they do little modalities like heat and ultrasound that studies have not found to be beneficial in the long run. Instead, they use manual techniques that will strengthen and stabilize specific sections of the spine that are weak. Sorry, I am a PT and have had bad experiences with PT's that provide mainly feel good remedies instead of manual therapy.
