Few research in multiple sclerosis (MS) has focused on physical
rehabilitation of upper limb dysfunction, though the latter strongly influences
independent performance of activities of daily living.
Upper limb rehabilitation
technology could hold promise for complementing traditional MS therapy.
Consequently, this pilot study aimed to examine the feasibility of an 8-week
mechanical-assisted training program for improving upper limb muscle strength and
functional capacity in MS patients with evident paresis. METHODS: A case series
was applied, with provision of a training program (3x/week, 30 minutes/session),
supplementary on the customary maintaining care, by employing a
gravity-supporting exoskeleton apparatus (Armeo Spring). Ten high-level
disability MS patients (Expanded Disability Status Scale 7.0-8.5) actively
performed task-oriented movements in a virtual real-life-like learning
environment with the affected upper limb. Tests were administered before and
after training, and at 2-month follow-up. Muscle strength was determined through
the Motricity Index and Jamar hand-held dynamometer. Functional capacity was
assessed using the TEMPA, Action Research Arm Test (ARAT) and 9-Hole Peg Test
(9HPT). RESULTS: Muscle strength did not change significantly. Significant gains
were particularly found in functional capacity tests. After training completion,
TEMPA scores improved (p = 0.02), while a trend towards significance was found
for the 9HPT (p = 0.05). At follow-up, the TEMPA as well as ARAT showed greater
improvement relative to baseline than after the 8-week intervention period (p =
0.01, p = 0.02 respectively). CONCLUSIONS: The results of present pilot study
suggest that upper limb functionality of high-level disability MS patients can be
positively influenced by means of a technology-enhanced physical rehabilitation program.
