Abstract

CONTEXT:

Scapular strength deficits have been linked to shoulder dysfunction.

OBJECTIVE:

To establish normative data on the scapulothoracic musculature in normal subjects using a handheld dynamometer.

DESIGN:

Descriptive normative data study.

SETTING:

Field research.

SUBJECTS:

172 subjects with varying levels of overhead activity.

METHODS:

A handheld dynamometer was used to test the upper, middle, and lower trapezius; rhomboids; and serratus anterior.

MAIN OUTCOME MEASURES:

A 2-factor ANOVA was performed for each of the muscles by activity level and unilateral ratio by activity-level analyses. Post hoc analysis included multiple pairwise comparisons, using the Dunn-Bonferroni correction method.

RESULTS:

Activity level did not significantly affect the unilateral ratios: Elevation:depression was 2.5:1, upward:downward rotation was 1.5:1, and protraction:retraction was 1.25:1. A rank order from strongest to weakest was established through significant comparisons.

CONCLUSION:

The unilateral ratios along with the rank order should be considered when discussing scapular rehabilitation protocols.
