Design outcomes

Primary

Measure	Time frame
1. Shoulder isometric external rotation strength (measured with a handheld dynamometer [HHD]) after 18 weeks 2. Internal rotation range of motion after 18 weeks	—

Secondary

Measure	Time frame
1. Isometric ER strength by HHD at weeks 6 and 12 2. IR ROM at weeks 6 and 12 3. Isometric muscular strength by HHD in IR at weeks 6, 12 and 18 4. ER/IR isometric ratio at weeks 6, 12 and 18 5. Isokinetic ER and IR, concentric at 60 and 300°/sec and eccentric at 60°/sec, both absolute values and the functional deceleration ratio (FDR) ERecc/IRcon at 60°/sec at 18 weeks 6. IR at weeks 6, 12 and 18 7. Total rotational ROM at weeks 6, 12 and 18	—
