A Descriptive Cross-Sectional Study of Manipulative Dexterity on Different Subtypes of Multiple Sclerosis.

PMID 32425718WHAT IT FOUND
People with relapsing-remitting, primary progressive and secondary progressive MS all showed poor hand dexterity.
Subtype differences were not clear except on one hand test. A hand test predicted up to 21.8% of how able participants felt in daily tasks.
Key findings
01Patients with relapsing-remitting, primary progressive and secondary progressive MS had lower hand dexterity scores than normative data, and the primary progressive group had the lowest values.
02Differences between MS subtypes were not statistically significant except for the Purdue Pegboard Test.
03The Purdue Pegboard Test predicted up to 21.8% of self-perceived ability in daily tasks, while self-perception did not correlate significantly with other dexterity tests.

What it does not show
Only 30 of 35 recruited participants were analysed, and the MS subtype groups were unbalanced, so comparisons between subtypes are limited. Participants were volunteers recruited by convenience sampling from MS care centres in Madrid, Spain. The sample was restricted to people aged 25 to 60, with no recent flare-ups, no cognitive decline, and an Expanded Disability Status Scale score of six or lower, so the findings may not apply to older adults, people in relapse, people with cognitive decline, or people with more severe disability. The study measured participants at one time point, so it cannot show that hand test scores caused differences in self-perception or function.
The easy way to misread this
Do not read the lowest primary progressive scores as proof that this subtype causes worse hand dexterity. The study did not find significant subtype differences except on the Purdue Pegboard Test, and only 30 participants were analysed.
