- Abstract
- A compliant brace (EDGES) promoting spastic elbow relaxation was designed to investigate the potentialities
of pseudoelastic NiTi in orthotics. By exploiting its peculiar characteristics, EDGES could improve
elbow posture without constraining movements and thus avoiding any pain to the patient. A commercial
Ni50.7-Ti49.3 alloy heat treated at 400 !C 1 h + WQ was selected for this application. A prototype of EDGES
was assembled with two thermoplastic shells connected by polycentric hinges. Four 2-mm-diameter NiTi
bars were encastred in the upper-arm shell and let slide along tubular fixtures on the forearm. Specially
designed bending tests demonstrated suitable moment-angle characteristics. Two post-stroke subjects (aged
62 and 64, mild elbow flexors spasticity) wore EDGES for 1 week, at least 10 h a day. No additional
treatment was applied during this period or the following week. A great improvement (20!±5!) of the
resting position was observed in both patients as early as 3 h after starting the treatment. Acceptability was
very good. A slight decrease in spasticity was also observed in both subjects. All the effects disappeared
1 week after discontinuation. EDGES appears to be a good alternative to traditional orthoses in terms of
acceptability and effectiveness in improving posture, especially whenever short-term splinting is planned. (literal)
