Effectiveness of Static Quadriceps Stretching in Individuals With Patellofemoral Joint Pain

Abstract

This study confirms the effectiveness of a 3-week static stretching regimen for enhancing quadriceps flexibility and knee joint function, but fails to demonstrate a statistical relationship between quadriceps flexibility and the severity of knee pain and joint dysfunction in a PJPS population.

Alongamento muscular segmentar melhora função e alinhamento do joelho de indivíduos com síndrome femoropatelar: estudo preliminar

“…Resultados semelhantes foram encontrados por Alaca et al (3) , que realizaram exercícios isocinéticos para fortalecimento e alongamento muscular de membros inferiores e também avaliaram a capacidade funcional pela escala de contagem de Lysholm. Peeler e Anderson (7) obtiveram melhora da intensidade da dor e da capacidade funcional em pacientes com SFP após três semanas de alongamento muscular segmentar do músculo quadríceps femoral, porém utilizaram formas de avaliação dessas variáveis diferentes das adotadas no presente estudo.…”

“…Este desequilíbrio desencadeia mau alinhamento patelar, dor e, consequentemente, diminuição da propriocepção (6) . A alteração da sensação de posição articular (SPA) pode também estar relacionada com a diminuição da flexibilidade, pois o encurtamento muscular promove um mau alinhamento patelar desencadeando dor (7) . Porém, ainda não há estudos na literatura que comprovem a eficácia do alongamento muscular na melhora da propriocepção.…”

Does Quadriceps Atrophy Exist in Individuals With Patellofemoral Pain? A Systematic Literature Review With Meta-analysis

“…Of these, 2 were randomized controlled trials 11,41 and 8 were cross-sectional studies (TABLE 3). 1,10,20,22,26,29,32,40 The primary aim of 5 studies was to assess quadriceps muscle size.…”

“…10,22,26,29,40 The remaining studies measured quadriceps muscle size as anthropometric data or as a secondary measurement of impairment associated with PFP. 1,11,20,32,41 The data from 7 studies were included in meta-analyses, as they reported the mean and standard deviation of the size of the quadriceps musculature. 10,20,22,26,29,40,41 Two studies reported the proportion of participants with quadriceps atrophy, 1,32 and therefore were not included in the meta-analyses.…”

One further study was not included in the meta-analyses because this study required quadriceps atrophy for a diagnosis of PFP 11 and selecting a subgroup of patients with PFP based on quadriceps atrophy as a criterion for diagnosis might introduce bias.…”
