Impact of load expectations on neuromuscular and postural strategies during a freestyle lifting task in individuals with and without chronic low back pain.

However, although mean quadriceps sEMG activity seem to increase with heavier load expectations compared to lighter load expectation (Mean lighter load expectations = 0.87 ± 0.39; Mean heavier load expectations = 0.89 ± 0.40), results did not reach statistical significance (F(1,44) = 3.55, p = 0.066, η 2 p = 0.07).
