Impact of Core Performance on Functional Parameters in Multiple Sclerosis

Optimal trunk control relies on somatosensory, motor and musculoskeletal integrity, which is often damaged in multiple sclerosis (MS). Researches on postural control in people with MS (PwMS) have revealed that reduced somatosensory conduction may adversely affect some functions. PwMS have increased postural sway in upright posture than healthy people. They move closer and slower when reaching out or taking a step. Trunk controls are weak and postural responses are delayed. The activation of core muscles is very important for an effective trunk control. Because the core region is considered a kinetic link that facilitates the transfer of torque and angular momentum between the upper and lower extremities during body movements. The decrease in core stability affects both trunk control and the quality of limb movements due to the kinetic chain in the body. There are a limited number of studies in the literature showing that core stability is reduced in PwMS. Our knowledge about the effects of this reduction on function in PwMS is very limited.
