“…While both studies showed significant increases, there was no significant difference between the exercise types (p=0.82). Increased insertion length is a phenomenon often associated with an increase in muscle volume [27], which is supported by the results reported here. A weak inverse relationship was noted between initial insertion length and insertion length change (R 2 =-0.17), which echoes the relationship seen in fibre angle change The mean insertion ratio (i.e., insertion length/patella length expressed as a percentage) increased by 6.15% ±9.89 in the OCKE group, and by 7.97% ±4.91 in the CCKE group.…”

“…Jan et al, [27] reported smaller VMO fibre angle in PFPS patients relative to controls, though there is wide variation. The findings reported here tend to support the suggestion by Khoshkhoo et al, [18] that a simple ultrasound screening test could be employed in clinic to identify patients with a low initial fibre angle, for whom VMO strengthening exercises might be most effective.…”

“…The ultrasound technique used in this study followed the method that has been validated and described in several previous studies [18,[25][26][27][28][29]. Participants were positioned supine on the examination couch; a pillow was placed under the ankles to immobilise the lower limbs.…”

“…The application of ultrasound in investigations into skeletal muscle architecture has been demonstrated in multiple studies (e.g., [23,24]). The method used here has been validated [25], and has been used in previous investigations into the VMO [18,[26][27][28][29].…”

Background: Recent discussions have compared the use of closed-chain and open-chain kinetic exercises in the management of patellofemoral pain. Literature shows disparity over the preferred method. While the clinical effectiveness of the two different approaches has been compared, there is no information in the literature on the effect of these exercise types on the vasti muscles of the thigh. This study compared the impact of open-chain and closed-chain exercise regimes on the architecture of the vastus medialis oblique. Methods: Vastus medialis oblique architecture was measured using ultrasound in 23 young, asymptomaticvolunteers. Matched subjects were then assigned to one of two six-week exercise programmes, using either closed-chain or open-chain kinetic exercises. Results: Both groups showed a significant increase in mean vastus medialis oblique fibre angle, (from 70.27° to 74.5° [OCKE] of both open-chain and closed-chain exercises. However, no significant difference was found between the two groups. Conclusions:The results of this study suggest that both open-chain and closed-chain exercise regimes have an equal effect on the architecture of the vastus medialis oblique after six weeks of exercise therapy.

“…The distal oblique fibres are thought to play a pivotal role in the kinematics and alignment at the patellofemoral joint (Berry et al , 2008, Fagan and Delahunt, 2008, Lin et al , 2008 and physiological or biomechanical dysfunction of this muscle are reported to contribute to patellofemoral pain (PFP) (Lankhorst et al , 2012). Recent research has used RUSI to assess the pennation angle of these oblique muscle fibres in cadaveric specimens (Engelina et al , 2012) and assess muscle volume in individuals with PFP (Lin, Lin, 2008, Jan et al , 2009. There is, however, a need to assess the validity of RUSI measurements of vastus medialis (VM).…”

Stokes, M. (2014) "Validity of measuring distal vastus medialis muscle using rehabilitative ultrasound imaging versus magnetic resonance imaging". Manual Therapy, 19(3) pp259-263The final, fully proofed and peer-reviewed journal article is available from the publisher online, via the following link: http://www.sciencedirect.com/science/article/pii/S1356689X14000137 Objective: This study aimed to validate RUSI against MRI for the linear measurements of the distal fibres of vastus medialis muscle in the thigh.Twelve healthy male participants were recruited from a local university population. The distal portion of their right vastus medialis was imaged with the participant in long-sitting, using MRI and RUSI whilst the leg was in extension and neutral hip rotation. Cross sectional area (CSA) and three linear measures were taken from the MRI and compared with the same linear measures from RUSI.Statistical analysis included comparison of MRI and RUSI measures using the paired t-test and correlation using intra-class correlation coefficients (ICC 3,1).Mean differences between the linear measures taken from the MRI and RUSI were -0.5mm to 2.9mm (95% confidence intervals -0.6 to 8.3mm), which were not statistically different (p>0.05) and were highly correlated (ICCs3,1 0.84-0.94). Correlations between the three linear measurements and muscle CSA ranged from r=0.23 to 0.87, the greatest being muscle thickness. Multiplying the linear measures did not improve the correlation of 0.87 found for muscle thickness.Linear measures of vastus medialis depth made using RUSI were shown to be as valid as using MRI.Muscle thickness measures using RUSI could be used within an objective assessment of this muscle.
