Evaluation of Interoception, Fatigue, and Upper and Lower Extremity Functional Capacity in Multiple Sclerosis Patients With Good and Poor Sleep Quality

Summary

Multiple sclerosis (MS) is a chronic disease of the central nervous system associated with a wide range of motor and non-motor symptoms. Sleep disturbances, fatigue, altered interoceptive perception, and impairments in upper and lower extremity functional capacity are commonly observed in individuals with MS. Decreased sleep quality may exacerbate fatigue and negatively affect daily activities and independence. Therefore, examining the relationships between sleep quality, interoception, fatigue, and extremity functional capacity is essential for effective disease management and the preservation of quality of life in individuals with MS. The aim of this study is to compare interoception, fatigue, and upper and lower extremity functional capacity between individuals with MS who have good and poor sleep quality and to evaluate the relationships among these variables. By comparing MS patients based on sleep quality, this study seeks to clarify the impact of sleep quality on interoceptive processes, fatigue levels, and functional capacity.
