Dear Editor:

It was with great interest that we read the recent article

by Shanley et al titled ‘‘Shoulder Range of Motion Measures

as Risk Factors for Shoulder and Elbow Injuries in

High School Softball and Baseball Players.’’1 We were

somewhat confused by some of the results and feel that

additional clarification might help with comparison to the

current literature and for planning future studies.

The overall upper extremity injury rate is reported as

2.5 injuries per 1000 athlete-exposures (AEs). It is further

reported that the upper extremity injury rate for pitchers

was 1.1 per 1000 AEs and 1.4 per 1000 AEs for nonpitchers.

This is confusing. How can the overall injury rate be

substantially higher than the injury rate for either pitchers

or nonpitchers? The overall injury rate should approximate

the average of the injury rate between pitchers and

nonpitchers, likely lying closer to that of nonpitchers given

that there were substantially more nonpitchers in the

study (195 nonpitchers vs 51 pitchers).
