ABSTRACT
Objective@#We evaluated the efficacy of a newly-developed spinal orthoses (V-LSO) by comparing the stabilizing effect, abdominal pressure, and comfort of 3 different semirigid LSOs (classic LSO, V-LSO, and CybertechⓇ ) during various body movements. @*Methods@#Thirty healthy volunteers (23∼47 years, 24 males, 6 females) were selected. A dual inclinometer measured the range of motion (ROM) while the participants performed flexion/extension and lateral flexion of the lumbar spine with 3 LSOs.The LSO’s pressure on the abdominal surface was measured using 9 pressure sensors while lying, sitting, standing, flexion/extension, lateral flexion, axial rotation, and lifting a box. Comfort and subjective immobilization were analyzed by a questionnaire. @*Results@#V-LSO had a statistically significant effect on flexion over CybertechⓇ . No significant differences were noted during extension and lateral flexion between the 3 LSOs. The abdominal pressure showed no significant differences while supine. While sitting, standing, and lifting a box, the mean abdominal pressure for V-LSO were significantly higher than those for Cybertech Ⓡ . During lumbar flexion, the mean abdominal pressures for classic LSO and V-LSO were significantly higher than that of CybertechⓇ . For extension, lateral flexion and axial rotation, the abdominal pressure for V-LSO was significantly higher than those of classic LSO and CybertechⓇ . In the subjective analysis, V-LSO and CybertechⓇ scored best for comfort. @*Conclusion@#The V-LSO and CybertechⓇ were more comfortable than the classic LSO, and hence, may have improved compliance with decreased discomfort. V-LSO may be superior to the other LSOs in restricting lumbar movement and increasing intraabdominal pressure.
