How effective is an evidence-based exercise intervention in individuals with patellofemoral pain?
2021, Physical Therapy in SportCitation Excerpt :The American College of Sports Medicine outlined that a training outlined above is recommended for novice training (American College of Sports, 2009). Compared to participants with PFP in previous studies, the participants with PFP in this study produced higher isometric quadriceps strength (Duvigneaud, Bernard, Stevens, Witvrouw, & Van Tiggelen, 2008; Dvir et al., 1990; Oliveira, Saad, Felício, & Grossi, 2014; Rathleff et al., 2013; Van Tiggelen, Witvrouw, Coorevits, Croisier, & Roget, 2004). Thus, the participants with PFP in this study appeared to be stronger than subjects in previous studies and the strength endurance training was very likely not demanding enough to improve quadriceps strength.
Ultrasonographic assessment of quadriceps and patellar tendon thicknesses in patients with patellofemoral pain syndrome
2019, Acta Orthopaedica et Traumatologica TurcicaCitation Excerpt :Quadriceps muscle is among the most important supporting structures of the patellofemoral joint. Observational studies have reported decreased quadriceps torque in subjects diagnosed with PFPS.4,8–10 A recent meta-analysis has demonstrated a significant relationship between quadriceps atrophy and presence of PFPS, when compared with the asymptomatic extremity and a healthy control group.11
Patellofemoral Pain
2016, Physical Medicine and Rehabilitation Clinics of North AmericaCitation Excerpt :Quadriceps muscle weakness has long been implicated in PFP. Observational studies have reported an association between reduced quadriceps torque19–21 and volume20,22 in patients with PFP. A recent meta-analysis further established a significant correlation between quadriceps atrophy and PFP, both when compared with the asymptomatic limb and when compared with a distinct control group.23
Maximality of shoulder external rotation effort in patients presenting with work related injury: The clinical applicability of the DEC parameter
2013, Journal of Electromyography and KinesiologyCitation Excerpt :This situation has been observed on occasion and was related to either pain or apprehension (or both). Inasmuch as pain is concerned, a longer exposure to loads developed by contracting muscle/s, which invariably happens when the test velocity is lower (in this case 30°/s), has been previously associated with much diminished strength score in patello–femoral pain syndrome (Dvir et al., 1990). This mechanism may well operate in patients exerting maximal shoulder external rotation effort where pain where discomfort or apprehension could inhibit full expression of the involved muscles’ capacity.
Sit-to-stand movement in children with hemiplegic cerebral palsy: Relationship with knee extensor torque and social participation
2013, Research in Developmental DisabilitiesCitation Excerpt :Peak torque was defined as the largest torque achieved during the movement, which represents the ability to produce maximal strength, and average peak torque was defined as the average of all the peak torques from each trial. Data were normalized by body weight and multiplied by 100; N/KgX100 (Dvir et al., 1990). Kinematic analysis of STS movement was chosen to evaluate “activity” ICF domain.
