Trunk control: The essence for upper limb functionality in patients with multiple sclerosis

We found that patients with MS would present impaired upper-limb movement and decreased trunk control with high correlation between them, even in RRMS and in the very mild form of the disease. Identifying trunk control deficits provides better insight into dexterous difficulties of patients with MS and allows a more targeted neurorehabilitation focusing on upper limbs. In future studies, it would be of interest to examine the prognostic value of trunk control and upper-limb functionality in patients with MS using a longitudinal approach.
