Physical Activity Implementation Guide
1.0.0 - STU Release 1 United States of America flag

This page is part of the U.S. Physical Activity IG (v1.0.0: STU 1.0) based on FHIR R4. This is the current published version. For a full list of available versions, see the Directory of published versions

Resource Profile: PA Observation - EVS, Strength Days/Week

Official URL: http://hl7.org/fhir/us/physical-activity/StructureDefinition/pa-observation-strength-days-per-week Version: 1.0.0
Standards status: Trial-use Maturity Level: 2 Computable Name: PAObservationStrengthDaysPerWeek

A profile for observations that capture a patient’s average days per week of muscle-strengthening physical activity.

This is the final Base Measure used by this implementation guide. It can also be compared to national guidelines based on age to assess patient physical activity level.
