1 Exploring the Clinical Course of Neck Pain in Physical Therapy: A Longitudinal Study 
David M. Walton, PhD, Yaara Eilon-Avigdor, MClSc, Michael Wonderham, MClSc, Piotr Wilk, PhD  Archives of Physical Medicine and Rehabilitation  Volume 95, Issue 2, Pages (February 2014) DOI: /j.apmr Copyright © 2014 American Congress of Rehabilitation Medicine Terms and Conditions

2 Fig 1 Mean trajectories for each of (A) NDI and (B) NRS. Solid line, estimated curve; dashed line, observed curve. Archives of Physical Medicine and Rehabilitation  , DOI: ( /j.apmr ) Copyright © 2014 American Congress of Rehabilitation Medicine Terms and Conditions

3 Fig 2 (A) Curves representing the 3 latent class trajectories in the NDI data. Solid line, worsening group (14.5%); dashed line, rapid improvement group (19.6%); dotted line, slow improvement group (65.8%). (B) Curves representing the 2 latent class trajectories in the NRS data. Solid line, stable group (47.9%); dashed line, improving group (52.1%). Note that in both cases, data have been centered around 0 (mean value – baseline mean) for descriptive purposes. See text for descriptions of slope.
