MCA plot of point clouds with hierarchical cluster analysis. Four cluster solution for the M. trapezius left (A), the M. trapezius right (B) and the M. levator scapulae right (D); three cluster solution for the M. levator scapulae (C) due to the limited number of identified complementary diagnostic criteria. (The four cluster solution subsumed two individuals with opposite coordinates on dimension 1, because they shared the rare yes-category for muscular weakness.) Dim1: dimension 1; Dim2 = dimension 2
