MTS total score and MTS shoulder score also decreased in the active compared to the sham condition, and these changes approached significance at discharge (MTS total: P = 0.0616, t = 1.945, Welch’s t -test, sham = –0.49 ± 0.38, active = –1.60 ± 0.50; MTS shoulder: P = 0.051, U = 88.5, Mann-Whitney U-test, sham = –0.25 ± 0.24, active = –0.72 ± 0.25; Figure 3B ).
