To better understand the development and natural course of neuro-musculoskeletal pain in the immediate post-OHS period, this prospective longitudinal study assessed the prevalence and degree of pain and shoulder disability, and areas of pain pre- and post-OHS. Usual medical, nursing, and physiotherapy care was provided including early extubation, education, walking, sitting out of bed, and upper, lower limb, and trunk exercises from day 1 post-operation. Of 114 elective patients who provided consent, 98 subjects were surveyed preoperatively, and at week 6 and week 12 post-OHS.
