In a study published in 1997 in Physiotherapy Theory and Practice, not only
did we not find any correlation between muscle strength and posture
pre-intervention, but we strengthened weak muscles (abdominals) for eight
weeks (as well as prescribing full exercise programs intended to alter
pelvic tilt and lumbar lordosis) and found that after an intensive
eight-week course of PT (3x/week supervised with home program bid), posture
(pelvic tilt and lumbar lordosis) had not changed at all. We later studied
these variables dynamically using specially designed rigs for the Vicon
motion analysis system and again found no correlations between muscle
strength and posture dynamically (walking).
