The objective of this study will be to investigate the additional effect of pain neuroscience education program compared to a craniocervical manual therapy and exercises program for pain intensity and disability in patients with temporomandibular disorders (TMD). This study will be a randomized controlled trial comprising a sample of 148 participants. Subjects between 18 and 55 years, both genders, will undergo a screening process to confirm painful TMD by the Research Diagnostic Criteria (RDC/TMD), and then the volunteers will be randomized into two groups (G1: pain neuroscience education + craniocervical manual therapy and exercises vs. G2: craniocervical manual therapy and exercises). The volunteers will be recruited at the dentistry clinic. The intervention will be administered twice a week for 6 weeks by a single therapist lasting 1 h per session. The primary outcome will be pain intensity and disability and the secondary outcomes will be pain self-efficacy, kinesiophobia, and global perceived effect of improvement. The participants will be assessed immediately after the last session and at one- and three-month follow-ups. All statistical analyses will be conducted following intention-to-treat principles, and the treatment effects will be calculated using linear mixed models. The results of this study may contribute to understand the additional effect of pain neuroscience education intervention on TMD patients submitted to manual therapy and exercise.

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.

Background: Hip and knee muscle weaknesses have been associated with the onset of anterior knee pain (AKP). Therefore, the understanding of how squats exercises can be performed in order to optimize the electrical activity of these muscles is relevant for physical therapy treatments., Objective: To compare the electromyographic activity of patella and pelvic stabilizers during traditional squat and squat associated with isometric hip adduction or abduction in subjects without AKP., Methods: Electromyography signals were captured using double-differential electrodes at the vastus medialis obliquus (VMO), vastus lateralis obliquus (VLO), vastus lateralis longus (VLL) and gluteus medium (GMed) in 15 healthy and sedentary women during squats exercises: traditional and associated with hip adduction and hip abduction with load of 25% of body weight. Linear mixed models with significance level of 5% were used for data analysis., Results: Squat associated with hip adduction and abduction produced electromyographic activity of GMed of 0.47 (0.2) and 0.59 (0.22) respectively, while conventional squat produced an electromyiographic activity of 0.33 (0.27). The higher VMO activity was 0.59 (0.27) during the isometric contraction in the squat associated with hip adduction. The higher VLO activity was 0.60 (0.32) during isometric contraction in the squat associated with hip abduction., Conclusion: Squat exercise associated with hip adduction increased VMO muscle activity as well as the activity of GMed activity.
