RT Journal Article SR Electronic T1 Assessment of Physical Functioning: A Conceptual Model Encompassing Environmental Factors and Individual Compensation Strategies JF Physical Therapy JO Phys Ther FD American Physical Therapy Association SP 705 OP 714 DO 10.2522/ptj.20080213 VO 89 IS 7 A1 Tomey, Kristin M. A1 Sowers, MaryFran R. YR 2009 UL http://jcore-reference.highwire.org/content/89/7/705.abstract AB Commonly studied physical functions include activities such as walking and climbing stairs.

This article presents a new conceptual model for assessment of relevant physical functioning while accounting for habitual environmental factors and compensation strategies.
