Physical activity participation according to the pyramidal, sensory, and cerebellar functional systems in multiple sclerosis.

The objective of the study was to examine the differences in physical activity participation with the pyramidal, cerebellar, and sensory functional systems in people with multiple sclerosis (PwMS). This cross-sectional study included 289 PwMS with a median EDSS of 2.0 (range 0-6.5) and a mean disease duration of 6.8 (SD = 8.4) years. The Godin leisure-time exercise questionnaire (GLTEQ) assessed physical activity participation. The sample was divided into seven groups according to the pyramidal, cerebellar, and sensory functional system scores derived from the EDSS data. Additionally, PwMS were divided into three physical activity subgroups (active, moderately active, and insufficiently active). Furthermore, PwMS were categorized into four levels of disability based on their global Expanded Disability Status Scale (EDSS) score [very mild (0-1.5), mild (2.0-3.5), moderate (4.0-5.5), and severe (6.0-6.5)]. In the physical activity subgroups, 159 (55.0%) were classified as insufficiently active, 59 (20.4%) as moderately active, and 71 (24.6%) as active. Pyramidal, cerebellar, and sensory impairments were demonstrated in 134 (46.4%), 73 (25.3%), and 85 (29.4%) patients, respectively. No differences were found for the GLTEQ scores for all seven functional system groups (P value = 0.168). As for the EDSS disability subgroups, the percentage of active patients (moderately at least) were 60%, 45.8%, 36.5%, and 15.4%, for the very mild, mild, moderate, and severe subgroups, respectively. This study found that participation in leisure-time physical activity is independent from the pyramidal, cerebellar, and sensory functional systems in PwMS.
