Cover Story: Muscle-specific fatigue can be measured using twitch electrical stimulation and changes in muscle acceleration. As the muscle fatigues, the reduced force of muscle contractions corresponds to decreases in the size of the twitch accelerations. The figure shows representative acceleration values (resultant vector) for a participant at 2, 4, and 6 Hz. The advantage of this test is that it can be performed using an inexpensive triaxial accelerometer, and it does not require force transducers that would be difficult to place on the lower back. The large reductions in muscle-specific endurance of the lower back muscles in healthy adults suggest a target for therapy to reduce lower back pain and dysfunction. View this paper.
