Camptocormia, which is rarely observed in patients with PD described the extreme forward-bending trunk position known as bent spine syndrome, a condition in which the trunk flexes abnormally when standing or walking but disappears in the supine position. This clinical case includes a 73 year-old male patient diagnosed with PD and sleep bruxism bruxism, presenting Camptocormia, symptoms of tremor, back pain, rigidity, bradykinesia, postural instability, limited mouth opening, decreased facial expression, and fatigue. Width of the mouth opening, mobility, functionality, range of motion, fatigue severity, language, speech and swallowing functions, and quality of life were evaluated before and after treatment. In this study, a detailed evaluation of the patient and a physiotherapeutic treatment protocol were created and performed along with pharmacological treatment focused on diminishing pain, improving mouth opening, swallowing functions and the tone of facial muscles, decreasing tone of abdominal muscles and stretching abdominal fascia, strengthening of the back extensor muscles and core muscles, and improving balance.eninfo:eu-repo/semantics/openAccessCamptocormiaPhysiotherapyRehabilitationParkinson DiseaseBruxismArticle1510210610.4328/ACAM.22384WOS:001413459700013Q40000-0003-4710-9540
