The purpose of the study is to analyze the effects of a mat Pilates intervention on the postural alignment and balance of breast cancer women receiving hormone therapy. A two-arm randomized clinical trial included 34 breast cancer survivors divided randomly between a mat Pilates group (n = 18), that performed 16 weeks of mat Pilates exercises, and a control group (n = 16), who were invited to maintain their daily routine activities and received three educational sessions. Data collection occurred at baseline and at post-intervention time. The postural alignment was assessed using the Postural Assessment Software (SAPO) and the balance was assessed by the MINIBESTest. When the two-way ANOVA was performed on postural alignment results, a significant statistical difference was found in the angle between acromions and the anterior-superior iliac spines of the mat Pilates group (p = 0.036). When compared to the post-intervention period, the mat Pilates method had an improved horizontal alignment of the anterior-superior iliac spines (p = 0.039) and vertical alignment of the acromion head on the right side (p = 0,016). Also, the participants of the Pilates group showed a significant statistical difference in the balance (p = 0.034). The control group had an improved vertical trunk alignment on the left side (p = 0,048). The control group and the mat Pilates method group improved in some aspects, however the mat Pilates method was effective in improving the postural alignment and the balance of breast cancer survivors receiving hormone therapy and may be recommended in oncological rehabilitation as a type of complementary therapy.

Influence of exercises on patellar height in women with patellofemoral pain syndrome.

Acta Ortop Bras 2014 ;22(2):82-5

Universidade de São Paulo, Faculdade de Medicina de Ribeirão Preto, Ribeirão Preto, SP, Brazil, Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo, Ribeirão Preto, SP, Brazil.

Objective: To evaluate the patellar height of volunteers with and without patellofemoral pain syndrome (PPS) during maximal voluntary isometric contraction (MVIC) in open kinetic chain (OKC) and closed kinetic chain (CKC) exercises.

Methods: Twenty healthy women, and nineteen women with patellofemoral pain syndrome were evaluated and subjected to nuclear magnetic resonance imaging during rest and MVIC in OKC and CKC at 15°, 30°, and 45° knee flexion. The patellar height was assessed by the K-Pacs program,using the Insall-Salvati index. For each exercise and knee position, patellar height was measured three times and the procedure was repeated after seven days.

Results: These data did not confirm our hypothesis that OKC exercises promote increased patellar height.

Conclusion: Patellar height is not associated with PPS and suggests that CKC exercises lead an increased patellar height during knee position at 15º and 45º flexion for the PPS group. Level of Evidence II, Comparative Prospective.

Contribution of the evaluation of the clinical signals in patients with patellofemoral pain syndrome.

Acta Ortop Bras 2013 Jul;21(4):198-201

Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo, Ribeirão Preto, SP, Brazil.

Objective: As patellofemoral pain syndrome (PFPS) is a common disorder characterized by multifactorial etiology and whose the most prevalent symptom is a diffuse pain, usually located on the retropatellar region, however, it also shows signs and symptoms that can be related as excessive subtalar pronation, external tibial torsion, patellar displacement alterations, painful range of motion of the knee, pain in the patellar borders, muscular tightness and changes in quadriceps angle (Q Angle), the objective of this work was to determine the frequency of these signs and symptoms associated to a previous knee pain questionnaire.

Methods: Thirty-nine sedentary female volunteers had been evaluated, divided in two groups, PFPS (19) and Control (20). These subjects were evaluated for signs and symptoms described above, in addition to pain assessment by questionnaire.

Results: The results demonstrated a high frequency of pain in six of the thirteen questions in relation to the control group.

Conclusion: According to these findings, we conclude that the functional evaluation of individuals with PFPS should consist of a previous knee pain questionnaire and an evaluation of the characteristic signs and symptoms for examination of the entire lower limb during static and functional situations. Level of Evidence II, Diagnostic Studies.

Correlation between trochlear groove depth and patellar position during open and closed kinetic chain exercises in subjects with anterior knee pain.

J Appl Biomech 2012 Jul;28(3):335-42

Program in Orthopedics, Traumatology and Rehabilitation, Ribeirão Preto School of Medicine, University of São Paulo, São Paulo, Brazil.

The purpose of this study was to correlate the trochlear shape and patellar tilt angle and lateral patellar displacement at rest and maximal voluntary isometric contraction (MVIC) exercises during open (OKC) and closed kinetic chain (CKC) in subjects with and without anterior knee pain. Subjects were all women, 20 who were clinically healthy and 19 diagnosed with anterior knee pain. All subjects were evaluated and subjected to magnetic resonance exams during OKC and CKC exercise with the knee placed at 15, 30, and 45 degrees of flexion. The parameters evaluated were sulcus angle, patellar tilt angle and patellar displacement using bisect offset. Pearson's r coefficient was used, with p < .05. Our results revealed in knee pain group during CKC and OKC at 15 degrees that the increase in the sulcus angle is associated with a tilt increase and patellar lateral displacement. Comparing sulcus angle, patellar tilt angle and bisect offset values between MVIC in OKC and CKC in the knee pain group, it was observed that patellar tilt angle increased in OKC only with the knee flexed at 30 degrees. Based on our results, we conclude that reduced trochlear depth is correlated with increased lateral patellar tilt and displacement during OKC and CKC at 15 degrees of flexion in people with anterior knee pain. By contrast, 30 degrees of knee flexion in CKC is more recommended in rehabilitation protocols because the patella was more stable than in other positions.

Analysis of patellar stabilizers muscles and patellar kinematics in anterior knee pain subjects.

J Electromyogr Kinesiol 2011 Feb 6;21(1):148-53. Epub 2010 Oct 6.

Traumatology and Rehabilitation Program, Ribeirão, Preto School of Medicine, University of São Paulo, USP, Brazil.

Patella stabilizer muscle response and patellar kinematics were evaluated in 19 women with anterior knee pain (AKP) and 20 healthy women during maximum voluntary isometric contraction (MVIC) with the knee positioned at 15°, 30° and 45° flexion during open (OKC) and closed (CKC) kinetic chain exercises. Patellar kinematics was evaluated through patellar tilt and displacement, and the electrical activity of patellar stabilizers through the root mean square normalized during MVIC and OKC with the knee at 90° flexion. Data revealed that the vastus medialis oblique muscle (VMO) was more active in the control group compared to the AKP group during OKC exercises with the knee at 45° flexion. However, no difference in the patellar kinematics was observed between these groups; nevertheless, the correlation between these parameters also showed, with the knee at 45° flexion, that lateral patellar tilt increase was associated with a reduction in the activity of lateral patellar stabilizers in the control group and with an increase in the VMO activity in the AKP group. In conclusion, electrical activity is an important factor in evaluating AKP and in AKP treatment evolution.

Evaluating patellar kinematics through magnetic resonance imaging during open- and closed-kinetic-chain exercises.

J Sport Rehabil 2010 Feb;19(1):1-11

Ribeirão Preto School of Medicine, University of São Paulo, Brazil.

Purpose: To evaluate patellar kinematics of volunteers without knee pain at rest and during isometric contraction in open-and closed-kinetic-chain exercises.

Methods: Twenty individuals took part in this study. All were submitted to magnetic resonance imaging (MRI) during rest and voluntary isometric contraction (VIC) in the open and closed kinetic chain at 15 degrees, 30 degrees, and 45 degrees of knee flexion. Through MRI and using medical e-film software, the following measurements were evaluated: sulcus angle, patellar-tilt angle, and bisect offset. The mixed-effects linear model was used for comparison between knee positions, between rest and isometric contractions, and between the exercises.

Results: Data analysis revealed that the sulcus angle decreased as knee flexion increased and revealed increases with isometric contractions in both the open and closed kinetic chain for all knee-flexion angles. The patellar-tilt angle decreased with isometric contractions in both the open and closed kinetic chain for every knee position. However, in the closed kinetic chain, patellar tilt increased significantly with the knee flexed at 15 degrees. The bisect offset increased with the knee flexed at 15 degrees during isometric contractions and decreased as knee flexion increased during both exercises.

Conclusion: VIC in the last degrees of knee extension may compromise patellar dynamics. On the other hand, it is possible to favor patellar stability by performing muscle contractions with the knee flexed at 30 degrees and 45 degrees in either the open or closed kinetic chain.
