“…This result is contrary to the findings of previous studies and our hypothesis. Previous authors found decreased torque in hip extension, hip abduction, 18,26 knee extension, 27 and hip external rotation 18 as compared with control participants. We expected to find many differences in hip and knee strength, so it is interesting that we found none.…”

“…In our study, the PFP cohort scored higher on the AKPS than other cohorts of PFP participants, showing they had less pain during daily activities. 25,26 Because many differences have been noted between the sexes for this condition, we focused our study on women, who have a higher incidence of PFP. 1 Although no differences in isometric muscle strength were present, women with PFP had increased activity of the VMO, decreased activity of the GMax and BicFem, less kneeflexion excursion, greater hip internal-rotation moment, and less time to peak trunk flexion and lateral flexion during the landing phase of the DVJ.…”

Context Patellofemoral pain (PFP) is one of the most prevalent knee conditions observed in women. Current research suggests that individuals with PFP have altered muscle activity, kinematics, and kinetics during functional tasks. However, few authors have examined differences in lower extremity biomechanics in this population during the drop-vertical jump (DVJ). Objective To determine how lower extremity electromyography, kinematics, and kinetics during a DVJ and lower extremity isometric strength differed between women with and those without PFP. Design Cross-sectional study. Setting Laboratory. Patients or Other Participants Fifteen healthy women (age = 20.23 ± 1.39 years, height = 169.32 ± 5.38 cm, mass = 67.73 ± 9.57 kg) and 15 women with PFP (age = 22.33 ± 3.49 years, height = 166.42 ± 6.01 cm, mass = 65.67 ± 13.75 kg). Intervention(s) Three trials of a DVJ. Main Outcome Measure(s) Surface electromyography, kinematics, and kinetics were collected simultaneously during a DVJ. Lower extremity strength was measured isometrically. Independent-samples t tests were performed to assess group differences. Results Normalized muscle activity in the vastus medialis (healthy group = 120.84 ± 80.73, PFP group = 235.84 ± 152.29), gluteus maximus (healthy group = 43.81 ± 65.63, PFP group = 13.37 ± 13.55), and biceps femoris (healthy group = 36.68 ± 62.71, PFP group = 11.04 ± 8.9) during the landing phase of the DVJ differed between groups. Compared with healthy women, those with PFP completed the DVJ with greater hip internal-rotation moment (0.04 ± 0.28 N/kg versus 0.06 ± 0.14 N/kg, respectively) and had decreased knee-flexion excursion (76.76° ± 7.50° versus PFP = 74.14° ± 19.85°, respectively); they took less time to reach peak trunk flexion (0.19 ± 0.01 seconds versus 0.19 ± 0.02 seconds, respectively) and lateral trunk flexion (0.12 ± 0.07 seconds versus 0.11 ± 0.04 seconds, respectively). Conclusions During the DVJ, women with PFP had increased hip internal-rotation moment and decreased knee-flexion excursion with less time to peak trunk flexion and lateral flexion. Muscle activation was increased in the vastus medialis but decreased in the gluteus maximus and biceps femoris. This suggests that altered motor-unit recruitment in the hip and thigh may result in changes in biomechanics during a DVJ that are often associated with an increased risk of injury.

“…Poor adherence to exercise-based interventions are also reported in adolescents with PFP due to factors such as school commitments, time constraints and boredom with the program [ 12 , 19 , 20 ]. Adolescents with PFP also typically report pain in both knees, with up to 79% reporting bilateral symptoms of PFP compared to 43% of adults with PFP [ 21 ]. This bilateral nature may increase the time commitment of prescribed exercise therapy [ 12 , 21 ].…”

“…Adolescents with PFP also typically report pain in both knees, with up to 79% reporting bilateral symptoms of PFP compared to 43% of adults with PFP [ 21 ]. This bilateral nature may increase the time commitment of prescribed exercise therapy [ 12 , 21 ]. Given adolescents with PFP do not demonstrate reduced muscular capacity, and their adherence to prescribed exercise therapy may be reduced, alternative treatment options that focus on patellofemoral joint load reduction may be more advantageous within this population.…”

Background There are limited evidence-based treatment options for adolescents with patellofemoral pain (PFP). Flat, flexible footwear have been shown to reduce patellofemoral joint loading and pain in adults with PFP. The efficacy of this intervention in adolescents with PFP is not established. The primary aim of this study is to determine the feasibility of conducting a large-scale randomised controlled trial (RCT) of the effect of flat, flexible school footwear, when compared to traditional school footwear, in adolescents with PFP. The secondary aim is to describe changes in self-reported outcome measures for adolescents with PFP while wearing flat, flexible footwear when compared to traditional school shoes. Methods Twenty-four adolescents with PFP will be recruited from the community. Following baseline assessment, participants will be randomly allocated to receive either (i) flat, flexible school footwear or, (ii) traditional school footwear. Participants will wear the shoe as per school requirements throughout a 12-week intervention period. Feasibility will be assessed with (i) ≥ 75% adherence to allocated shoe wear of their total weekly school wear time, (ii) a recruitment rate of one participant per fortnight, and (iii) a dropout rate of ≤ 20%. Patient reported outcome measures will describe changes in knee pain, function, quality of life and global rating of change at 6 and 12 weeks. Descriptive statistics will be used for the primary outcomes of feasibility. Discussion This study will determine the feasibility of conducting a large scale RCT evaluating the effect of flat, flexible school shoes for adolescents with PFP. A full-scale study will guide evidence-based management of adolescent PFP. Trial registration Australian New Zealand Clinical Trials Registry reference: ACTRN12621001525875, Date registered: 9th November 2021.

“…Se suele tener en cuenta como primera opción la terapia basada en la realización de ejercicios, sin embargo el 62% de los adolescentes con dolor femoropatelar siguen teniendo síntomas tras un año de tratamiento con ejercicios (13). Las ortesis plantares pese al amplio abanico de funciones que realizan hay poca documentación acerca de su eficacia estructural y funcional (14).En el caso del dolor femoropatelar, se cree que este control de la bóveda plantar es clave para frenar la rotación interna de la tibia y el fémur y también la pronación del pie. Con esto se reduce el estrés provocado por los impactos entre la rótula y el fémur (15).…”

Objetivo: El objetivo principal de este trabajo es analizar la evidencia científica en relación a la efectividad de los soportes plantares para tratar el dolor femoropatelar.Material y métodos: Se realizó una búsqueda bibliográfica en cuatro bases de datos (Pubmed, Cochrane, Science Direct y Dialnet). Los términos empleados en la búsqueda fueron: patelofemoral pain syndrome, treatment, orthoses y orthotics. Se tuvieron en cuenta los artículos de los últimos 15 años que hablaran de soportes plantares a medida y prefabricados, que no combinaran las plantillas con otra terapia y que no fueran revisiones sistemáticas.Resultados: Se revisó un total de 10 artículos al completo. Tanto las ortesis a medida como las prefabricadas obtuvieron buenos resultados, aunque a largo plazo fueron mejores las plantillas a medida.Conclusión: Los soportes plantares son una buena alternativa al tratamiento del síndrome de dolor patelofemoral.
