This group (near Stanford with other locations) has some effective methods to help clients reduce pain or discomfort and improve physical ability.

The Balance Center - http://www.balancecenter.com/overview.htm

I am not afilliated, but have known several people to go through their program with life changing results.

As I understand it:

They have traveled around the world studying populations of people which have a low incident of back pain and old-age disability [1]. They observed those groups to have posture and movement habits that are subtly different from populations having a high incident of such problems. Their effective training program improves clients comfort and ability by teaching them the habits observed in the low-pain low-disability groups.

[1] area's similar to a Blue Zone - https://en.wikipedia.org/wiki/Blue_Zone - but apparently chosen for prevelence of comfort and ability instead of simply highest age.
