Effects of a new sensory re-education training tool on hand sensibility and manual dexterity in people with multiple sclerosis.

OBJECTIVE To describe and evaluate the effects of a new home-based sensory re-education training tool on hand sensibility and manual dexterity in people with MS experiencing upper limb sensory deficits. METHODS Twenty-five people with relapsing-remitting MS (18 women), mean age 50.6 years (SD = 11.4), volunteered to participate. Participants were initially assigned to a 7-week control phase followed by a 3-week home-based sensory re-education phase. Measurements used were the nine-hole peg test, the two point discrimination test, the monofilaments test and the functional dexterity test. Measurements were collected at baseline, following the control phase and at the end of the trial. RESULTS Participants demonstrated an improvement in the nine-hole peg (26.8 (SD = 3.5) vs. 22.6 (SD = 3.2); mean difference (95% CI) 4.9 (0.9, 7.1), P = 0.03) and functional dexterity tests (38.6 (SD = 4.4) vs. 33.8 (SD = 4.9); mean difference (95% CI) 4.8 (1.8, 7.0); P = 0.02) at the end of the sensory re-education phase compared to the end of the control phase. No differences were observed as to the monofilaments and two-point discrimination tests. CONCLUSIONS Sensory re-education training does not affect the level of sensory impairment in the hand but may lead to improvement in select measures of manual dexterity.
