The present case study illustrates the case of a 47-year-old female (Ms X) with primary progressive Multiple Sclerosis (MS) who presented with central post-stroke pain (CPSP) over her left shoulder and underwent acupuncture treatment (AT) since she appeared irresponsive to conventional treatment. The aim of this case study is to explore the effectiveness of acupuncture as a complimentary treatment in improving central neurogenic pain in MS patients affected by CPSP. AT lasted six weeks, some modification of the conventional AT points was required to ensure continuity and safety of the treatment plan. In fact, Ms X suffered from gingivitis that led to hypersensitivity of her left upper limb (UL) to acupuncture needling; moreover, she experienced sensation loss in her legs as a result of post-stroke complications. The outcome showed that the subject's shoulder range of motion (ROM), Disabilities of the Arm, Shoulder and Hand (DASH) score and pain improved remarkably, enabling Ms X to resume post-stroke rehabilitation and reduce her analgesic intake.
