Thigpen, Charles A., et al. "Head and shoulder posture affect scapular mechanics and muscle activity in overhead tasks." Journal of Electromyography and kinesiology 20.4 (2010): 701-709.
Forward head and rounded shoulder posture (FHRSP) is theorized to contribute to alterations in scapular kinematics and muscle activity leading to the development of shoulder pain. However, reported differences in scapular kinematics and muscle activity in those with forward head and rounded shoulder posture are confounded by the presence of shoulder pain. Therefore, the purpose of this study was to compare scapular kinematics and muscle activity in individuals free from shoulder pain, with and without FHRSP. Eighty…

Salomoni, Sauro, et al. "Reduced maximal force during acute anterior knee pain is associated with deficits in voluntary muscle activation." PloS one 11.8 (2016): e0161487.
Although maximal voluntary contraction (MVC) force is reduced during pain, studies using interpolated twitch show no consistent reduction of voluntary muscle drive. The present study aimed to test if the reduction in MVC force during acute experimental pain could be explained by increased activation of antagonist muscles, weak voluntary activation at baseline, or changes in force direction. Twenty-two healthy volunteers performed maximal voluntary isometric knee extensions before, during, and after the effects of hypertonic (pain)…

Hall, Leanne, et al. "Immediate effects of co-contraction training on motor control of the trunk muscles in people with recurrent low back pain." Journal of electromyography and kinesiology 19.5 (2009): 763-773.
Although deficits in the activation of abdominal muscles are present in people with low back pain (LBP), this can be modified with motor training. Training of deep abdominal muscles in isolation from the other trunk muscles, as an initial phase of training, has been shown to improve the timing of activation of the trained muscles, and reduce symptoms and recurrence of LBP. The aim of this study was to determine if training of the trunk muscles in a non-isolated manner can restore motor control of these muscles in people with LBP. Ten…

Marshall, P., and B. Murphy. "The validity and reliability of surface EMG to assess the neuromuscular response of the abdominal muscles to rapid limb movement." Journal of Electromyography and Kinesiology 13.5 (2003): 477-489.
The transversus abdominus muscle (TrA) has been demonstrated to be active prior to rapid movements of the upper and lower limbs. This activity is termed feed forward motivation. The lack of feed-forward activation for TrA has been demonstrated in subjects with low back pain. The measures used for investigation of TrA function have been fine-wire needle EMG. This limits the practical application of TrA study due to the cost and level of specialisation required for this technique. The objective of the current study was to investigate the validity…
