The previous two tests use the weight of the legs as the resistive load. The forearm plank test, also referred to as a prone bridge, has been theorized to be more functional because it provides for assessment of endurance during an activity requiring simultaneous activation of the entire anterior muscular chain (Bliss and Teeple, 2005). This lower back holding time does not differ between coal miners with a past history of low back pain and those without. Trunk extensor-to-flexor muscles imbalances are major contributors to the etiology of back pain (Moffroid, 1997).
