Training Load, Pain Intensity, and Functioning Can Explain Injuries in Dancers: A Classification and Regression Tree (CART) Analysis.

Objective: To identify the biopsychosocial factors that explain injuries in dancers through use of a Classification and Regression Tree (CART) analysis.

Methods: Cross-sectional study performed with dancers over 18 years of age from dance schools in Brazil. Sociodemographic factors, pain intensity (numerical pain rating scale, NPRS), anxiety (Beck anxiety inventory, BAI), and functioning (WHO Disability Assessment Schedule 2.

Epidemiology and associated factors for CrossFit-related musculoskeletal injuries: a cross-sectional study.

Background: CrossFit® is usually composed of high intensity workout routines and is executed quickly, repetitively and with limited rest time. Previous studies have identified a high prevalence of injuries in CrossFit®. This study aimed to determine the prevalence of CrossFit-related musculoskeletal injuries and to identify potential associated factors.

BIOMECHANICAL DIFFERENCES IN BRAZILIAN JIU-JITSU ATHLETES: THE ROLE OF COMBAT STYLE.

Background: Brazilian Jiu-Jitsu (BJJ) athletes can be divided into two combat styles: pass fighters (PFs) and guard fighters (GFs). Flexibility of the posterior chain muscles is highly necessary in these athletes, especially in GFs. On the other hand, isometric strength of the trunk extensors is required in PFs.

Relationship between frontal plane projection angle of the knee and hip and trunk strength in women with and without patellofemoral pain.

Background: It is theorized that increased dynamic knee valgus relates to decreased hip posterolateral muscle strength.

Objective: The aim here was to assess the relationship between the frontal plane projection angle (FPPA) of the knee and hip and trunk muscle strength in women with and without patellofemoral pain (PFP).

Methods: The sample comprised 43 women: Patellofemoral Pain Group (PPG, n = 22) and Control Group (CG, n = 21).

Q-angle in patellofemoral pain: relationship with dynamic knee valgus, hip abductor torque, pain and function.

Objective: To investigate the relationship between the q-angle and anterior knee pain severity, functional capacity, dynamic knee valgus and hip abductor torque in women with patellofemoral pain syndrome (PFPS).

Methods: This study included 22 women with PFPS. The q-angle was assessed using goniometry: the participants were positioned in dorsal decubitus with the knee and hip extended, and the hip and foot in neutral rotation.

Anatomical glenohumeral internal rotation deficit and symmetric rotational strength in male and female young beach volleyball players.

Beach volleyball is a sport with a high demand of shoulder structures that may lead to adaptations in range of motion (ROM) and strength like in other overhead sports. Despite of these possible alterations, no study evaluated the shoulder adaptations in young beach volleyball athletes. The aim of this study was to compare the bilateral ROM and rotation strength in the shoulders of young beach volleyball players.

Does anterior knee pain severity and function relate to the frontal plane projection angle and trunk and hip strength in women with patellofemoral pain?

The aim of the present study was to determine the relationship between knee pain severity and function with the frontal plane projection angle (FPPA) and trunk and hip peak torque (PT) in women with patellofemoral pain (PFPS). Twenty-two women with PFPS were assessed. Knee pain severity (KPS) was assessed with an 11-point visual analog scale and function with an Anterior Knee Pain Scale.

The effects of exertion on the postural stability in young soccer players.

Objective: : Analyze the effects of physical exertion during a soccer match on the functional capacity and stability of the lower limbs of young soccer players.

Methods: : We analyzed 10 soccer players who underwent functional capacity assessment of the lower limbs by a Hop Test protocol and evaluation of the level of postural stability in the Biodex Stability System (Biodex, Inc., Shirley, NY) before and immediately after a friendly game lasting 45 minutes.

Manual therapy and therapeutic exercise in patient with symptomatic cervical spondylotic myelopathy: a case report.

Cervical spondylotic myelopathy (CSM) is caused by narrowing of the cervical spinal canal, although surgical decompression is an obvious indication for spinal cord stenosis, there are not enough data to determine that surgery is the most indicated intervention for milder forms. The purpose of the present case report was to describe the outcomes results of the physical therapy treatment with emphasis on manual therapy and therapeutic exercise for a patient with CSM. A 58-year-old male patient attended the physical therapy clinic due to pain and paresthesia in the upper and lower limbs.

Efficacy of graded activity versus supervised exercises in patients with chronic non-specific low back pain: protocol of a randomised controlled trial.

Background: Low back pain is a relevant public health problem, being an important cause of work absenteeism worldwide, as well as affecting the quality of life of sufferers and their individual functional performances. Supervised active physical routines and of cognitive-behavioral therapies are recommended for the treatment of chronic Low back pain, although evidence to support the effectiveness of different techniques is missing. Accordingly, the aim of this study is to contrast the effectiveness of two types of exercises, graded activity or supervised, in decreasing symptoms of chronic low back pain.

The effects of one-half of a soccer match on the postural stability and functional capacity of the lower limbs in young soccer players.

Objective: Most injuries occur during the final 15 minutes of each half of a soccer match, suggesting that physical exertion may influence changes in neuromuscular control and the body's ability to stabilize the joints of the lower extremities. The aim of this study was to analyze the effects of one-half of a soccer match on the functional capacity and stability of the lower limbs in young soccer players.

Methods: We analyzed 27 soccer players by evaluating the functional capacity of their lower limbs using the hop test protocol and their level of postural stability using the Biodex Stability System.

Glenohumeral range of motion in handball players with and without throwing-related shoulder pain.

Background: Overhead athletes are subject to adaptations in the shoulder including glenohumeral internal rotation deficit (GIRD). It has been documented that this alteration is more evident in overhead athletes with pain. Our objective was to compare glenohumeral rotation motion between symptomatic and asymptomatic handball players.

Comparison of hip rotation range of motion in judo athletes with and without history of low back pain.

This study compared hip rotation range of motion in judo athletes with and without a history of low back pain. Forty-two athletes (22 males) were divided into two groups: 21 with history of low back pain (HLBP) and 21 without history of low back pain (Control). Internal and external hip rotation range of motion in active and passive movement were measured using computed photogrammetry.
