Spinal manipulation and modulation of pain sensitivity in persistent low back pain: a secondary cluster analysis of a randomized trial

Table 7 Within changes in regional pressure pain threshold [kPa, 0–100] for each latent profile derived cluster faceted by segment allocation after spinal manipulation

Cluster group	Treatment allocation	Baseline to Post-SM	Baseline to Follow-up
Sensitized	Pain segment group	146 (68:224)*	118 (40:196)*
	Stiff segment group	93 (3:183)*	84(−6:174)
Not Sensitized	Pain segment group	87 (31:143)*	78 (22:135)*
	Stiff segment group	18(−37:73)	26(− 30:81)

Within mean changes (95% confidence intervals) from baseline to post-SM and follow up, respectively, in the two groups derived from latent profile analysis for each allocated SM segment group
