  This is the first meta-analysis to quantify the risk factors for NSCLBP in nurses. Being female, married, working night shifts, overweight, working at least 10 years and dissatisfied with work are risk factors. High-quality prospective studies are required to validate the findings of this study.

  Myofascial Pain Syndrome causes disability in daily life activities and despite all efforts, it continues to be a challenge, perpetuating suffering, overloading services and costs. New treatment options need to be tested.
 
  We aimed to quantify the rESWT short-term analgesic effect and identify the predictors of success through comparing results achieved in MPS and Articular Pain (AP).
 
  Retrospective cohort study of 1,580 patients with Myofascial Pain Syndrome or Articular Pain underwent two weekly radial Extracorporeal Shock-wave Therapy sessions. The pain intensity was measured by Visual Analog Scale before and one week after the end of the treatment (3 weeks).
 
  The therapy decreases pain by 62.50% (p< 0.0001), with a high success rate (91.59%) and a low worsening of baseline conditions rate (2.1%). The best recommendation is for patients with intense myofascial pain (Visual Analog Scale ⩾ 70mm), using high shock-wave frequency (⩾ 15 Hz).
 
  Two rESWT sessions promote pain relief, with a high success rate and low rates of treatment abandonment and worsening. The best results are obtained in myofascial pain patients with high pain intensity, treated with high-frequency dosage.

  New training methods are constantly used to improve the ability of skeletal muscles to develop strength.
 
  The aim of the present study was to investigate the effect of half-squat training with free weights and flywheel device on isokinetic knee muscle strength for well-trained amateur soccer players.
 
  Forty eight players were randomly divided into three groups (n= 16 each) Desmotech Training group (DT), Free Weight Training group (WT) and one Control Group (CON). DT and WT performed an eight-week half-squat training program, with two sessions per week. The DT group performed training with a flywheel device. Isokinetic concentric-eccentric strength assessments of the knee extensors-flexors muscle groups were performed at different angular velocities (60, 180 and 240∘/s).
 
  The eight-week training program improved all the isokinetic joint moment indicators examined in the DT and WT groups (p< 0.01). The DT group achieved higher performances at all the isokinetic parameters examined, however, without statistically significant differences to the WT group.
 
  Flywheel-based exercise is an effective training method and is suggested to be used to strengthen the lower limbs of soccer players.

  Sarcopenia has been found to affect the postoperative outcomes of lumbar surgery. The effect of sarcopenia on the clinical outcomes in patients who underwent stand-alone lateral lumbar interbody fusion (LLIF) has not yet been examined.
 
  To investigate whether sarcopenia affects the Oswestry Disability Index (ODI) and visual analog scale (VAS) score for back pain following single-level stand-alone LLIF.
 
  Patients who underwent a single level stand-alone LLIF for lumbar diseases were retrospectively investigated. Sarcopenia was defined according to the diagnostic algorithm recommended by the Asian Working Group for Sarcopenia. Patients were divided into the sarcopenia (SP) and non-sarcopenia (NSP) group. Univariate analysis was used to compare with regards to demographics and clinical outcomes. Multivariate logistic regression was performed to elucidate factors predicting poor clinically improvement.
 
  Sixty-nine patients were enrolled, with 16 and 53 patients in the SP and NSP group respectively. In the SPafter stand-alone LLIF.
  The cervical flexion relaxation phenomenon (FRP) is a myoelectric silence of neck extensor muscles which occurs after a certain degree of flexion. Impaired flexion relaxation can impose the vertebral structures to excessive loading resulting from the persistence of muscular contraction.
 
  This study aimed to investigate the incidence or absence of FRP in cervical erector spinae (CES) and upper trapezius muscles in patients with chronic neck pain (CNP).
 
  Twenty-five patients with CNP and 25 healthy volunteers were recruited. They accomplished cervical flexion and extension from a neutral position in four phases in the sitting position. The surface electromyography activity of both CES and upper trapezius muscles was recorded in each phase. Cervical flexion and extension movements were simultaneously measured using an electrogoniometer.
 
  FRP in CES was observed in 84% and 36% of healthy subjects and CNP patients, respectively. Flexion relaxation ratio (FRR) in CES was lower in CNP patients than in healthy subjects (mean diff = 1.33; 95% CI 0.75-1.91) (P< 0.001). Only in CNP patients, FRR in right erector spinea was significantly higher than that in the left erector spinea (P= 0.04).
 
  FRP incidence in CNP patients was less than in healthy subjects. Moreover, this phenomenon begins later in CNP patients than in healthy subjects indicating prolonged activity of CES muscles during flexion in the CNP group. The difference between FRR in the right and left sides of erector spinea muscles can result in CNP.
