“…The CSA of lumbar multifidus was compared using MRI and RUSI at vertebral levels from L2 to S1 and no significant differences were found, despite differences in position for imaging (Hides, Richardson, 1995). Measures of cervical multifidus muscle from C4 to C6 was also shown to be valid for thickness (R 2 = 0.42 to 0.64) but not for CSA (R 2 = 0.11 to 0.39) or width (R 2 = 0.16-0.69) (Lee, Tseng, 2007). The small CSA of the muscle (approximately 1 cm 2 ) may have amplified errors, thus influence the accuracy of measurements.…”

“…Several studies have reported RUSI as a valid method for measuring the size of muscles when compared to MRI, including; the lumbar multifidus (Hides et al , 1995), cervical multifidus (Lee et al , 2007), abdominals (Hides et al , 2006), trapezius (O'Sullivan et al , 2009), quadriceps (Walton et al , 1997, Reeves, Maganaris, 2004, Thomaes et al , 2012 and anterior hip muscles (Mendis et al , 2010). A systematic review of 13 studies on the validity of using RUSI compared with MRI or computed tomography (CT) concluded that RUSI can provide valid measurements of skeletal muscles (Pretorius and Keating, 2008).…”

“…In earlier studies, muscle size, shape, and symmetry, and the change in these parameters during activity compared to a resting state, were studied using ultrasound to describe reference values or capture abnormalities due to muscle atrophy or hypotrophy (Rezasoltani et al, 2002;Kristjansson et al, 2004;Rankin et al, 2005;Lee et al, 2007Lee et al, , 2009Fernández-De-Las-Peñas et al, 2008). However, the ultrasound technique cannot be used as a direct measure of activity and recruitment.…”

“…Traditional grey scale ultrasound, which has been used in previous studies of neck muscles (Rezasoltani et al, 1998(Rezasoltani et al, , 1999(Rezasoltani et al, , 2002Kristjansson, 2004;Rankin et al, 2005;Fernández-De-Las-Peñas et al, 2008;Jesus et al, 2008;Lee et al, 2009), provides information about anatomical landmarks and structural information about the tissue. Dorsal (Lee et al, 2007(Lee et al, , 2009) and ventral (Jesus et al, 2008) neck muscles have been studied using changes in muscle thickness or cross-sectional area (CSA) as an indication of muscle activity. Lee et al (2007Lee et al ( , 2009) studied the CSA of the multifidus muscle during rest and isometric head extension, finding that ultrasound can detect changes in multifidus during contraction, with acceptable reliability.…”
