Analysis of pain, functional capacity, muscular strength and balance in young women with Patellofemoral Pain Syndrome

Abstract

Introduction: Patellofemoral Pain Syndrome (PFPS) is associated with anterior knee pain, changes in functional capacity, balance and muscle strength disorders. Objective: To quantify pain, functional capacity, strength in quadriceps (Q), gluteus medium (GM), hip external rotator (ER) muscles and balance in sedentary women with PFPS. Methods: Twenty sedentary women, aged 18 to 25 years, were divided into two groups: PFPS (N=10) and control group (N=10). All the volunteers answered the items of the Visual Analogue Scale (VAS), the Lysholm Knee Score Scale, the Anterior Knee Pain Scale (AKPS), and the Lower Extremity Functional Scale (LEFS). The participants performed the following tests: maximal voluntary isometric contraction measured by dynamometry; postural balance using the Star Excursion Balance Test (SEBT) and a force platform. Statistical analyses were performed using the Shapiro Wilk test, the Mann Whitney U test and Spearman's correlation coefficient. Data were submitted to SPSS 20 software. Results: The PFPS group presented greater pain, balance impairment and higher average velocity of oscillation; however, no differences were observed in Q, GM and RE muscle strength and in balance analyzed by SEBT. Conclusion: Women with PFPS exhibited

Is Postural Control Affected in People with Patellofemoral Pain and Should it be Part of Rehabilitation? A Systematic Review with Meta-analysis

“…Subgroup and meta-regression analyses did not indicate potential sources of heterogeneity (Additional file 7 ). Overall postural stability (15 studies [ 24 , 26 , 27 , 57 , 86 – 90 , 92 , 95 , 98 , 99 , 101 , 102 ] ): Moderate level evidence indicated that there is no difference between people with and without PFP for overall balance (SMD 0.38, 95% CI − 0.05–0.82; Fig. 4 and Table 1 ).…”

“…Meta-regression indicated that age is not a source of heterogeneity (Additional file 7 ). Posteromedial (PM) postural stability (4 studies [ 85 , 95 , 96 , 98 ] ): Moderate level evidence indicated a very large and non-significant effect for lower reach during SEBT PM in people with PFP (SMD 1.22, 95% CI − 0.59–3.02; Fig. 5 and Table 1 ).…”

“…7 and Table 1 ). ML CoP Velocity (6 studies [ 58 , 87 , 88 , 91 , 95 , 100 ] ): Moderate level evidence indicated a moderate and non-significant effect for greater ML CoP velocity in people with PFP compared to controls (SMD 0.67, 95% CI − 0.20–1.55; Fig. 8 and Table 1 ).…”

Tratamento da síndrome da dor patelofemoral com treinamento neuromuscular: Uma breve revisão

“…A incidência nos Estados Unidos está entre 3% e 6%, a característica principal do PFPS é a dor na região anterior do joelho, que se intensifica quando o joelho é flexionado durante as atividades de levantamento de peso. A dor da PFPS, geralmente piora quando o indivíduo permanece sentado por período prolongado ou quando desce de escadas (Zamboti, et al, 2017).…”

“…O tratamento da PFPS inclui repouso, um curto uso de anti-inflamatórios não esteroidais e fisioterapia direcionada ao fortalecimento dos músculos flexores do quadril e joelho. A bandagem patelar kinesio pode fornecer alívio adicional da dor de curto prazo; entretanto, as evidências são insuficientes para apoiar seu uso rotineiro (Zamboti, et al, 2017).…”
