STUDY DESIGN This was a cross-sectional study involving 229 healthy, back pain-free individuals. OBJECTIVES To examine the relationship between electromyographic manifestations of fatigue and endurance time during isometric contraction of the back extensors to fatigue. SUMMARY OF BACKGROUND DATA Despite the wide-spread use of electromyography to monitor muscle fatigue, its relationship with endurance time has not been well investigated. METHODS Using skin-surface electrodes… CONTINUE READING
