title: Efficacy of lumbar mobilization on postpartum low back pain in Egyptian females: A randomized control trial.
abstract: BACKGROUND
  Low back pain (LBP) is a common complaint in the postnatal period. Physiotherapy has many techniques to apply for such cases.
  
  
  OBJECTIVE
  To investigate the effect of central postero-anterior (PA) lumbar mobilization on muscle activity in postpartum LBP.
  
  
  METHODS
  Forty-five females with chronic LBP at least three months postnatal. Participants divided randomly and equally into three groups. Group A (Study group) received PA lumbar mobilization plus traditional treatment which consisted of Ultrasonic and Infra-red. Group B (Placebo group) received placebo mobilization plus traditional treatment. Group C (Control group) received traditional treatment only. All patients received 3 sessions/week for 4 weeks. Pain intensity, functional disabilities and Surface EMG for recording para spinal muscle activity were measured before and after intervention. Statistical analysis was done by ANOVA and paired t-test.
  
  
  RESULTS
  Central PA mobilization showed a significant reduction (P< 0.05) in the average surface EMG activity of the erector spinae musculature compared with the other groups as well as improvement in functional ability and reduction in pain intensity.
  
  
  CONCLUSIONS
  A central PA mobilization significantly reduced pain intensity and surface EMG activity of erector spinae musculature as well as improvement in functional ability in mechanical low back pain in postnatal females.
