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.

Index of fatigue quadriceps in soccer athletes after anterior cruciate ligament reconstruction.

Objective: The present study aimed to evaluate the muscle fatigue of the quadriceps muscle in high-performance soccer players undergoing (anterior cruciate ligament) ACL reconstruction.

Methods: We evaluated 17 high-performance soccer players from three professional soccer teams of a state in Brazil from August 2011 to July 2012. All subjects were evaluated between 5.

Correlation between clinical tests and electroneuromyography for the diagnosis of leprosy neuropathy.

Background: In leprosy, sensory function of nerves is evaluated with monofilaments test and the motor function with voluntary muscle test, however electroneuromyography is considered as the gold-standard tool.

Objectives: This study aimed: i) to evaluate the correlation between clinical tests and electroneuromyography for the diagnosis of leprosy neuropathy; and ii) to identify the prevalence of leprosy neuropathy and the most compromised peripheral nerves in leprosy.

Methods: We analysed the data from a nested case-control study that identified 166 patients diagnosed with leprosy neuropathy confirmed by electromyography.

Concurrent validity of the pressure biofeedback unit and surface electromyography in measuring transversus abdominis muscle activity in patients with chronic nonspecific low back pain.

Background: The Pressure biofeedback unit (PBU) is an assessment tool used in clinical practice and research aimed to indirectly analyze the transversus abdominis (TrA) muscle activity. The concurrent validity of the PBU in a clinically relevant sample is still unclear.

Objective: The purpose of this study was to evaluate the concurrent validity and diagnostic accuracy of the PBU in measuring TrA muscle activity in patients with chronic nonspecific low back pain.

Reproducibility of the pressure biofeedback unit in measuring transversus abdominis muscle activity in patients with chronic nonspecific low back pain.

The Pressure Biofeedback Unit (PBU) is often used by clinicians and researchers to indirectly evaluate transversus abdominis (TrA) muscle activity. The purpose of this study was to evaluate the inter and intra-examiner reproducibility of the PBU in measuring TrA muscle activity in fifty patients with chronic nonspecific low back pain. This study was performed using a test-retest design with a seven day interval.
