“…15,38 In addition, hip eccentric torque has been associated with functional capacity and pain level in females with PFPS. 33 Although males and females with PFPS showed diminished hip external rotation eccentric torque, only females with PFPS demonstrated increased hip internal rotation during the single-leg squat. Souza and Powers 43 reported that the greater hip internal rotation motion occurring during running in women with PFPS was associated with diminished hip muscle performance, especially hip extension endurance.…”

Study Design Controlled laboratory study using a cross-sectional design. Objectives To determine whether there are any differences between the sexes in trunk, pelvis, hip, and knee kinematics, hip strength, and gluteal muscle activation during the performance of a single-leg squat in individuals with patellofemoral pain syndrome (PFPS) and control participants. Background Though there is a greater incidence of PFPS in females, PFPS is also quite common in males. Trunk kinematics may affect hip and knee function; however, there is a lack of studies of the influence of the trunk in individuals with PFPS. Methods Eighty subjects were distributed into 4 groups: females with PFPS, female controls, males with PFPS, and male controls. Trunk, pelvis, hip, and knee kinematics and gluteal muscle activation were evaluated during a single-leg squat. Hip abduction and external rotation eccentric strength was measured on an isokinetic dynamometer. Group differences were assessed using a 2-way multivariate analysis of variance (sex by PFPS status). Results Compared to controls, subjects with PFPS had greater ipsilateral trunk lean (mean ± SD, 9.3° ± 5.3° versus 6.7° ± 3.0°; P = .012), contralateral pelvic drop (10.3° ± 4.7° versus 7.4° ± 3.8°; P = .003), hip adduction (14.8° ± 7.8° versus 10.8° ± 5.6°; P<.0001), and knee abduction (9.2° ± 5.0° versus 5.8° ± 3.4°; P<.0001) when performing a single-leg squat. Subjects with PFPS also had 18% less hip abduction and 17% less hip external rotation strength. Compared to female controls, females with PFPS had more hip internal rotation (P<.05) and less muscle activation of the gluteus medius (P = .017) during the single-leg squat. Conclusion Despite many similarities in findings for males and females with PFPS, there may be specific sex differences that warrant consideration in future studies and when clinically evaluating and treating females with PFPS.

“…Powers et al 15 , suggest that the functional ability in people with PFPS is related to a higher quadriceps torque, given that the extensor torque was the only predictor of gait functioning, with a higher torque related to an improvement in the characteristics of the steps. In addition, Nakagawa et al 19 , found that the higher the knee eccentric extensor torque, the higher the functional capacity and the lower the pain intensity reported by the individuals with PFPS during the study's last week. Therefore, both the restoration of the strength of the muscle involved with knee functioning, especially the quadriceps, and the affected limb's regained capacity are important for the individual's recovery 24 .…”

“…The signs and symptoms of this syndrome are exacerbated especially during the performance of functional activities, among which we highlight the movements of going up and down the stairs and inclined surfaces 15,16 , which could result in the modification of locomotive patterns. Even so, this is a strategy adopted by these individuals in order to reduce muscle strain and, consequently, the pain [17][18][19] . These modifications in locomotive patterns may lead to alterations in the muscle strength of lower limbs, especially the quadriceps, given that this muscle is considered the knee's primary stabilizer during walking, especially during response to the load applied to it.…”

“…Some studies have been performed in order to evaluate the torque of knee flexors and extensors using isokinetic dynamometry on individuals with patellofemoral pain, but they differ in relation to test speed and contraction type 15,[18][19][20][21][22][23] . Some of these studies have associated the higher torque of knee flexors and extensors to a higher functional capacity in individuals with PFPS 15,19,24 .…”

“…Some of these studies have associated the higher torque of knee flexors and extensors to a higher functional capacity in individuals with PFPS 15,19,24 . In addition, only the study by Duffey et al, which evaluated the work of knee flexor and extensor muscles in individuals with PFPS, has been found to the present day.…”

Este estudo visou determinar a influência da Síndrome da Dor Patelofemoral (SDPF) sobre o pico de torque e trabalho da musculatura flexora e extensora do joelho, além de avaliar a dor e funcionalidade de sujeitos com a disfunção. Participaram 52 sujeitos do gênero feminino, 23 com SDPF e 29 clinicamente saudáveis similares em idade, estatura e massa corporal. A avaliação isocinética foi realizada no modo concêntrico para os flexores e extensores do joelho nas velocidades de 60 e 180°/s. Também foi aplicada a Escala Visual Numérica antes e após cada velocidade do teste isocinético e o questionário de Kujala. Os dados foram analisados pela estatística descritiva e inferencial (testes U de Mann-Whitney, Wilcoxon e t independente) com nível de significância de α=0,05. O Grupo com Síndrome da Dor Patelofemoral (GSDPF) apresentou menor pontuação (p=0,01) no questionário de Kujala (75,7±12,3 pontos) em relação ao Grupo Controle (GC) (100±0,0 pontos), além de menor pico de torque, tanto em 60 como 180°/s, dos flexores (0,82±0,24 Nm/kg; 0,51±0,22 Nm/kg) e extensores (1,85±0,48 Nm/kg; 1,13±0,44 Nm/kg) do joelho, bem como menor trabalho total dos extensores do joelho a 180°/s (6,46±2,54 J/kg) e 60°/s (9,42±3,27 J/kg). Além disso, foi observado aumento da dor do GSDPF após a avaliação isocinética a 180°/s (0,9 cm) e 60°/s (2,3 cm). Os resultados evidenciaram que sujeitos com SDPF possuem menor capacidade funcional e menor pico de torque e trabalho dos flexores e extensores do joelho, sugerindo que o fortalecimento desta musculatura deve ser considerado na reabilitação destes sujeitos.
