Several muscle diseases are traditionally named after the topography of muscle affection. Attention to the involvement of the axial musculature, however, is scarce, possibly due to the difficulties in assessing strength in these muscles compared with muscles of the limbs and face. Consequently, the involvement of the axial musculature is largely unexplored in muscle diseases [1]. Recently, several magnetic resonance imaging (MRI) studies have described significant involvement of the paraspinal musculature in patients with facioscapulohumeral dystrophy (FSHD) [2], and limb-girdle muscular dystrophy (LMGD) types R1 [3], R2 [4] and R3 [3, 5]. However, no
