Master Sgt. Stephanie A. Martinez, 379th Expeditionary Medical Operations Squadron physical therapy assistant, works with U.S. Army Sgt. Karl Hawthorne, Combined Air Operations Center air defense communications and tactics specialist, on muscular strengthening exercises using stretch bands July 28, 2016, at Al Udeid Air Base, Qatar. The physical therapy clinic here sees approximately 300 patients a month, and while service members don't require a referral from their Primary Care provider before a visit, the condition should impact ones job performance before making an appointment.
