Aggravating activities in chronic low back ache are not specifically directional !!!

Classifiable self reported aggravating activities in chronic low back ache are: aggravation in flexion, extension or unilateral bending. Wand BM et al tried to find do the self-reported aggravating activities of people with chronic non-specific low back pain move the spine in a consistent direction? In an observational study they found there is no evidence for the existence of a consistent direction of spinal movement during the self-reported aggravating activities of people with chronic non-specific low back pain. Participants in this study were described as demonstrating a directional pattern if all three self-reported aggravating activities moved the spine in the same direction.

Result of the study by Wand BM et al:
In their study over 148 participants with three classifiable aggravating activities they found:
1. Only 47 (32%) demonstrated a directional pattern. And out of them
2. 46 (98%) demonstrated a flexion pattern and
3. 1 (2%) an extension pattern.
They have also asserted the observed incidence of a directional pattern in the three self-reported aggravating activities of the 148 participants (32%) was no different from what would have been expected by chance.
