Summary

A new shoulder activity scale was developed to measure how often patients engage in physical activities. This tool demonstrates excellent reliability and validity for predicting shoulder disorder outcomes.

Area of Science:

Orthopedics
Rehabilitation Medicine
Sports Medicine

Background:

Existing shoulder assessment tools primarily measure pain and function, neglecting patient activity levels.
Patient activity level is a crucial factor influencing the outcomes of shoulder disorders.
A validated measure of shoulder activity is needed to predict patient prognosis.

Purpose of the Study:

To develop a brief, easily administered measure of shoulder activity.
To assess the reliability and validity of the newly developed shoulder activity scale.
To establish the scale's utility in predicting outcomes for shoulder disorders.

Main Methods:

The shoulder activity scale was developed using established principles: item generation, reduction, pretesting, and reliability/validity testing.
The scale comprises five activities rated on a five-point frequency scale (0-4 points).
Additional questions assess participation in contact and overhead sports.

Main Results:

The developed activity scale demonstrated excellent reliability and construct validity.
The scale is quick to complete, facilitating its use in clinical settings.
The scale effectively measures shoulder activity frequency.

Conclusions:

The new shoulder activity scale is a reliable and valid tool for assessing patient activity levels.
This scale can be used alongside existing outcome measures to define patient cohorts.
Shoulder activity level, as measured by this scale, can serve as a prognostic factor in shoulder disorders.
