Table 2 Mean and standard deviations (SD) of differential value of muscle onset time between with and without ADIM in each group (n = 40)

From: Effect of abdominal drawing-in maneuver during hip extension on the muscle onset time of gluteus maximus, hamstring, and lumbar erector spinae in subjects with hyperlordotic lumbar angle

  LHLA (n = 20) LNLA (n = 20) Significance
HAM (ms) -0.07 ± 0.27 0.09 ± 0.22 NS
GM (ms) -0.53 ± 0.47 0.16 ± 0.61 P <0.01
LES (ms) 0.01 ± 0.38 0.04 ± 0.55 NS
  1. ADIM, Abdominal drawing-in maneuver; LHLA, Lumbar hyper lordotic angle; LNLA, Lumbar normal lordotic angle; HAM, Hamstring; GM, Gluteus maximus; LES, Lumbar erector spinae.
