Trends and advancements in shoulder biomechanics research.

The 12th International Shoulder Group (ISG) Conference was held at Mayo Clinic in Rochester, Minnesota, USA, from August 12-13, 2018, and was hosted by Dr. Melissa (Missy) Morrow of Mayo Clinic and Dr. Meghan Vidt of Pennsylvania State University. This conference was held as a satellite conference to the annual 2018 American Society of Biomechanics Conference. This Editorial accompanies the Special Issue of the Journal of Electromyography and Kinesiology, and contains a selection of the work presented during the 12th Meeting of the ISG. Fourteen full-length articles describe advancements in shoulder research relevant to both basic science and clinical outlets. The work presented herein spans the research areas of methodology, mechanistic understanding, and clinical management. These areas are synergistic and equally important to propel the field forward and enhance impact. These manuscripts reinforce the dedication of the ISG and its members and showcase the ongoing drive toward translational application of these concepts across the common themes of rotator cuff, muscle, wheelchair & ergonomics, and methods & modeling. Highlights of each of the special issue publications are described within the context of the current trends in shoulder research and areas for further advancement.
