Changes in actigraphy metrics associated with PROMIS measures after orthopaedic surgery.

Aim: This study examined the feasibility of integrating actigraphy devices into orthopaedic surgical settings to assess the concurrent validity between objective actigraphy data and PROMIS measures. Additionally, the association between changes in actigraphy data and longitudinal changes in PROMIS measures was examined.

Methods: Data were collected from 17 participants using actigraphy devices the week prior to and after orthopaedic surgery from 02/2019 to 03/2020.

Theory and empiricism: A comment on "Interrogating the environmental affordances model" by Pamplin and colleagues.

We strongly support efforts to generate, rigorously test, and falsify hypotheses derived from the Environmental Affordances (EA) Model of Health Disparities, as originated by the late Dr. James S. Jackson (1940-2020).
