Medical Outcomes Study SF-36: Physical functioning subscale score (Z-score)
Description

The subscale score is based on 10 items from the Medical Outcomes Study Short Form 36 (SF-36). A high score suggests the participant "performs all types of physical activities including the most vigorous without limitations due to health". Ware JE and Sherbourne CD, 1992 (PubMed ID: 1593914)
