Electromyographic Assessment of Functional Symmetry of Paraspinal Muscles during Static Exercises in Adolescents with Idiopathic Scoliosis

Table 2

Average values () of the ISBAM symmetry coefficient and results of the test of statistical significance (McNemar’s chi² test) of differences between the symmetry coefficient as measured “at rest” and symmetry coefficient as measured during individual symmetric and asymmetric exercises in subjects with C-shaped and S-shaped idiopathic scoliosis.
