“…For example, the angle in the Test EX-A is 0° (participants’ body is parallel to the floor) while in the Test EX-B, the angle is 45°; the angle in the Test FL-A is 60°, while in the Test FL-B, the angle is 45°; in the Test LM-A, the angle is approximately 20°, while in Test LM-B, the angle is 45°. Different angles described above cause a very different low back loading demands and torques that potentially affect the holding times in each testing position ( Tuff, Beach & Howarth, 2020 ).…”

“…One of the most reliable and frequently used endurance tests are tests proposed by McGill ( McGill, Childs & Liebenson, 1999 ; McGill, 2016 ). However, many authors have emphasized that the endurance of other muscles such as hip and shoulder muscles can contribute to the performance of above mentioned endurance tests ( Pagé, Dubois & Descarreaux, 2011 ; McGill, 2016 ; Tuff, Beach & Howarth, 2020 ; Castro-Piñero et al, 2021 ; Juan-Recio et al, 2022 ). Therefore, some of those testing positions are not suitable for some groups of participants ( e.g.…”

“…Furthermore, the body position angle of inclination, as well as the type of the kinetic chain (open vs . closed) differs between the tests and therefore can affect the muscle activation and holding times ( Tuff, Beach & Howarth, 2020 ).…”

“…The difference in low back loading demands of the open- and closed-chain variations of some tests on the Roman chair were already studied. Authors wanted to determine if the recommended alternative 45° inclination angle for the open-chain testing position (when testing on the Roman chair) are a suitable approximation of the low back loading demands of the closed-chain testing position (when testing with tests proposed by McGill) ( Tuff, Beach & Howarth, 2020 ). For the lateral trunk muscles Tuff, Beach & Howarth (2020) obtained 45° inclination angle for the open-chain side bridge provides a suitable approximation of the low back lateral bend reaction moment in the closed-chain side bridge.…”

Background Adequate trunk muscle endurance is considered to be an important indicator of good low back stability; therefore, its assessment is needed when determining an individual’s risk for back pain. Optimal tests to assess each trunk muscle group separately are difficult to find. The objective of this study was to verify if two groups of trunk muscle endurance tests (standard and alternative) show comparable results in terms of muscle endurance ratios, holding times and rated perceived effort to perform each test. Methods The study was designed as a quasi-experimental repeated-measures design. There was a single group of participants who took part in two different trunk muscle endurance testing. Sixty-eight healthy adult volunteers, aged 20–45 years (31.9 ± 7.2 years), without recent musculoskeletal injury or disorder participated in the study. All participants finished the study. Trunk muscle endurance tests as tested on the Roman chair (B tests) were compared with standard tests as suggested by McGill (A tests). Each group of tests consisted of an endurance test for trunk extensors, trunk flexors, and lateral trunk muscles for left and right side. The order of tests’ performances was randomly assigned to each participant, whereby a participant did perform A and B tests in the same order. In each test of A and B the holding time was recorded and a perceived effort in each test performance was also assessed by participants. Post testing performance the four ratios of trunk muscles endurance comparison were calculated for each group of tests to determine if there is a good or poor ratio between muscles. Results of each participant were compared for trunk muscle endurance ratio calculations, holding times and rated perceived effort for A and B tests. Results Results showed comparable trunk muscle endurance ratios in the three ratios observed, except for the flexors:extensors ratio (AFL:EX: 1.2 (IQR: 0.7–1.6) vs. BFL:EX: 0.6 (IQR: 0.3–0.8); p < 0.001). As compared to A tests, holding times were significantly longer in B tests for the extensors (AEX: 125.5 s (IQR: 104.8–182.8 s) vs. BEX: 284.0 s (IQR: 213.0–342.3 s); p < 0.001) and lateral trunk muscles (AL-LM: 61.0 s (IQR: 48.3–80.8 s) vs. BL-LM: 131.5 s (IQR: 95.5–158.5 s); AR-LM: 63.5 s (IQR: 45.8–77.3 s) vs. BR-LM: 113.0 s (IQR: 86.3–148.8 s); p < 0.001), both were also rated as slightly easier to perform in the extensors (ARPE-EX: 13 (IQR: 12.0–14.0) vs BRPE-EX: 11 (IQR: 10.0–13.0); pRPE-EX < 0.001) and lateral muscles testing (ARPE-LM: 14.0 (IQR: 12.3–15.8) vs. BRPE-LM: 13.0 (IQR: 12.0–15.0); pRPE-LM = 0.001). Conclusions A and B tests are comparable in three of four trunk muscle endurance ratios, while longer holding times and lower perceived effort to perform were observed in most of the B tests. The Roman chair tests could be used as an alternative to standard tests.

“…As a result of this condition, there is a lack of coordination or muscle imbalance between these muscles during activity, and inappropriate movement patterns would be created (32,33). Restriction of spinal movement in people with low back pain may also decrease balance in these people, because with the motor restriction in the spine during the balance tests, the spine cannot perform the necessary movements and the person may have an impaired balance (34).…”

RESUMEN.El dolor anterior de rodilla es una condición que afecta a pacientes adolescentes y adultos jóvenes, siendo una de las consultas más comunes y desafiantes para el cirujano de rodilla. La gran cantidad de diagnósticos diferenciales, lo convierten en un síndrome particular, que solo presentan en común la presencia de dolor retro o peripatelar agravado por al menos una actividad que cargue la articulación en flexión. Desde un punto de vista fisiopatológico, debe considerarse una lesión por sobrecarga, donde la unidad estructural del tejido se encuentra dañada o excedida su capacidad de respuesta reparadora. El diagnóstico es clínico. Las imágenes debiesen reservarse para un grupo particular de pacientes. La intervención precoz es fundamental para lograr resultados favorables. El tratamiento conservador es el estándar de oro y se basa en un manejo multimodal validado por consensos internacionales. Basados en una categorización por clínica e imágenes, podemos tener una guía de aquellos cuadros que son susceptibles de manejo quirúrgico. El objetivo de la intervención es reducir el estrés articular. La presente revisión define un algoritmo simplificado de estudio y manejo en dolor anterior de rodilla.Palabras clave: dolor anterior de rodilla, síndrome dolor patelofemoral, adolescentes, diagnóstico, tratamiento. ABSTRACT.Anterior knee pain is a common condition that affects adolescent and young adult patients, being one of the most challenging consultations for a knee surgeon. The large number of distinct diagnoses makes it a peculiar syndrome, the only similarities being the presence of retro or peripatellar pain aggravated by at least one activity that loads the joint in flexion. From a pathophysiological perspective, an overuse injury should be considered, where the structural unit of the tissue is damaged or its capacity for reparative response is exceeded. The diagnosis is clinical. Images should be reserved for a particular group of patients. Early intervention is essential to achieve favorable results. Conservative treatment is the gold standard and it is based on multimodal management validated by international consensus. Based on a categorization by clinic and images, we can have a guide to those etiologies that are susceptible to surgical management. The goal of the intervention is to reduce joint stress. The present review defines a simplified algorithm for the study and management of anterior knee pain.
