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

Objetivo: Verificar a influência da SDPF na qualidade de vida, funcionalidade e dor de mulheres jovens. Métodos: A amostra foi composta por 20 participantes, com idades entre 19 e 24 anos, distribuídas em grupo SDPF (N=10) e controle (N=10). Estas responderam ao questionário Medical Outcome Study 36-item Short Form (SF36) de qualidade de vida, “Anterior Knee Pain Scale” (AKPS) para análise da funcionalidade e escala visual analógica (EVA). Para análise estatística utilizou-se os testes Shapiro Wilk, t Student e Correlação de Pearson, com o SPSS® 20. Resultados: No grupo com SDPF encontrou-se pior qualidade de vida, em específico para capacidade funcional (p=0,000), aspectos físicos (p=0,005), dor (p=0,000) e aspectos emocionais (p=0,031) do questionário SF-36. Também houve diferenças de funcionalidade (p=0,000) e dor (p=0,000) avaliadas em mulheres jovens. No grupo SDPF foi estabelecida forte correlação entre funcionalidade (AKPS) e capacidade física (r=0,874), dor (r=0,771), vitalidade (r=0,771) e saúde mental (r=0,743). Para o grupo controle, a AKPS apresentou forte correlação somente com o estado geral de saúde (r=0,715). Conclusão: Mulheres jovens com SDPF apresentam menor qualidade de vida, tanto para os domínios físicos como para os emocionais; pior funcionalidade e maior dor. Estes fatores devem ser considerados na avaliação e reabilitação de mulheres com SDPF, incluindo as mais jovens.

Objective: To investigate the reliability, internal consistency and validity of the Brazilian Portuguese version of the University of California San Diego Shortness of Breath Questionnaire (UCSD SOBQ) in patients with interstitial lung disease (ILD). Methods: Patients with ILD completed the questionnaire at three different time points, one week apart, with the assistance of two independent assessors. Intra- and inter-rater reliability were analysed via the intraclass correlation coefficient (ICC). Internal consistency was assessed with the Cronbach's alpha coefficient. For the validity analysis, associations between variables were assessed with Spearman's or Pearson's correlation coefficient. Results: Thirty patients with ILD (idiopathic pulmonary fibrosis, connective tissue disease-associated pulmonary fibrosis, sarcoidosis, asbestosis or non-specific interstitial pneumonia) were included (15 men; mean age, 59 ± 10 years; DLCO: 46 [33-64] % predicted). UCSD SOBQ scores showed excellent agreement and internal consistency in the intra-rater analysis (ICC: 0.93 [0.85-0.97]; Cronbach alpha: 0.95) and in the inter-rater analysis (ICC: 0.95 [0.89-0.97]; Cronbach alpha: 0.95), as well as correlating significantly with dyspnoea (as assessed by the Medical Research Council scale; r = 0.56); Medical Outcomes Study 36-item Short-Form Health Survey domains bodily pain, general health, vitality and physical functioning (-0.40 = r = -0.74); six-minute walk distance (r = -0.38); and quadriceps muscle strength (r = -0.41). Conclusions: The Brazilian Portuguese version of the UCSD SOBQ is valid, is reliable and has internal consistency in patients with ILD in Brazil.
