“…Cross-sectional studies have reported more consistent evidence for decreased hip abduction, extension and external rotation strength (Rathleff et al, 2014), along with a delayed and shorter duration of gluteal muscle activity during functional tasks (Barton, Balachandar, Lack, & Morrissey., 2014), in people with PFP. In addition, emerging evidence indicates rate of force development in females with PFP may also be slower when compared to asymptomatic females (Nunes, Barton, & Serrão, 2017), suggesting that muscle function variables in addition to strength should be of interest to those delivering PFP rehabilitation. Consistent with quadriceps findings, hip muscle weakness is reported to exist in older (15e19 y/o) but not younger (12e16 y/o) adolescents with PFP (Rathleff, Baird, et al, 2013).…”

“…Additionally, the majority of previous studies appear to focus on neuromuscular or strength-endurance prescription, despite stating a focus on strength in their titles (Lack et al, 2015). Considering possible deficits in strength (Rathleff et al, 2014) and muscle power (Nunes et al, 2017), we encourage clinicians to assess each patient for specific muscle function deficits, and prescribe a specific progressive resistance training program accordingly. Where necessary, design of an appropriate programme should aim to use accepted exercise prescription principles (Fig.…”

Patellofemoral pain (PFP) is one of the most prevalent conditions within sports medicine, orthopaedic and general practice settings. Long-term treatment outcomes are poor, with estimates that more than 50% of people with the condition will report symptoms beyond 5 years following diagnosis. Additionally, emerging evidence indicates that PFP may be on a continuum with patellofemoral osteoarthritis. Consensus of world leading clinicians and academics highlights the potential benefit of delivering tailored interventions, specific to an individual's needs, to improve patient outcome. This clinical masterclass aims to develop the reader's understanding of PFP aetiology, inform clinical assessment and increase knowledge regarding individually tailored treatment approaches. It offers practical application guidance, and additional resources, that can positively impact clinical practice.

“…However, the bridge test with unilateral knee extension is a quasi-static test and we evaluated isometric strength with the muscles at lengths similar to the muscles' lengths assumed during the bridge test. Future studies should investigate the relationship between core stability and different muscle functions, such as concentric and eccentric strength, 35 power, rate of force development 36 and endurance. Second, our sample had different levels of physical activity, which may influence the relationship between core muscles' strength and core stability.…”

Background: A better understanding about the relationship between trunk and hip muscles strength and core stability may improve evaluation and interventions proposed to improve core stability. Objectives: To investigate if trunk and hip muscles strength predict pelvic posterior rotation during the bridge test with unilateral knee extension. Methods: This is a cross-sectional study. Sixty-one healthy individuals of both sexes (age, 28 ± 6.4 years, weight, 66.5 ± 10.9 kg, height, 167 ± 9.5 cm) performed the bridge test with unilateral knee extension. The pelvic posterior rotation during the bridge test was obtained with two-dimensional video analysis. Isometric strength of the trunk extensors and rotators, and hip abductors, external and internal rotators and extensors were measured with a handheld dynamometer. Multiple linear regression analysis was performed to identify if the strength variables could explain the pelvic posterior rotation during the test. Results: Muscle strength predicted pelvic posterior rotation during the bridge test (r = 0.54; p = 0.003). Strength of the trunk rotators (p = 0.045) and hip internal rotators (p = 0.015) predicted reduced magnitude of pelvic posterior rotation during the bridge test, and strength of the hip extensors (p = 0.003) predicted increased magnitude of pelvic posterior rotation.

“…This can potentially be achieved by considering the acquisition of additional ultrasound measurements. An MT measurement of gluteus maximus has previously been acquired in elderly females (Ikezoe et al 2011), females with hip osteoarthritis (Fukumoto et al 2014), and physically active females (Nunes et al 2018). The larger muscle size in recreationally active males was a limitation to the acquisition of this measurement in the current study as the ultrasound probe could not achieve good quality images of the deep aponeurosis of gluteus maximus.…”

PurposeThis study aimed to identify a safe, rapid, and accessible method of estimating muscle volume of key lower limb muscle groups to reduce the time-demand of acquiring this measurement and potentially facilitate its application as a clinical monitoring tool.MethodsUnilateral MRI images were acquired from the 12th thoracic vertebrae to the base of the foot in 18 recreationally active males. Panoramic B-mode ultrasound images were acquired from the same leg at the mid-hip, 25%, 50%, and 75% of thigh length, and 25% of shank length. Body mass, height, limb lengths, and circumferences at the sites corresponding to the ultrasound images were acquired. A single investigator manually analysed all images. Regression analyses were conducted to identify models for estimating volume of the hip extensor, knee extensor and flexor, and ankle plantarflexor muscle groups.ResultsModels were developed for estimating hip extensor (SEE = 8.92%, R2 = 0.690), knee extensor (SEE = 5.24%, R2 = 0.707) and flexor (SEE = 7.89%, R2 = 0.357), and ankle plantarflexor (SEE = 10.78%, R2 = 0.387) muscle group volumes. The hip and knee extensor models showed good potential for generalisation. Systematic error was observed for the knee flexor and ankle plantarflexor models.ConclusionsHip extensor, knee extensor and flexor, and ankle plantarflexor muscle group volumes can be estimated using B-mode ultrasound images and anthropometric measurements. The error shown for each of the models was sufficient to identify previously reported differences in muscle volume due to training or injury, supporting their clinical application.
