Standard cervical thoracic orthoses outperformed comparable devices for restricting neck motion
Researchers found adjustable cervical orthoses provided outcomes comparable to standard devices for restricting neck motion in all three anatomical planes, while modular cervical thoracic orthoses provided poorer outcomes compared with their standard counterpart devices, according to the results of a this study.
Researchers compared the effectiveness of adjustable cervical orthoses (CO) and modular cervical thoracic orthoses (CTO) with standard devices in restricting neck motion. The researchers studied the devices in vivo in 27 healthy participants across prescribed loading levels ranging from 0.5 Nm to 2 Nm. The CO devices included the Vista collar and Vista multipost collar (Aspen Medical Products), and the modular CTOs included the Vista TS, Vista TS with multipost, and Vista TS4 with multipost (Aspen Medical Products). The standard devices included the Aspen collar and Aspen CTO (Aspen Medical Products).
According to the researchers, the Aspen CTO provided the best performance in terms of restricting movement and the adjustable COs provided the worst overall performance. The Aspen CTO was significantly more effective at motion restriction in both sagittal and frontal planes under loading more than 1.5 Nm compared with modular CTOs. Modular CTOs outperformed adjustable COs in most cases, but were comparable to the standard CO.
Researchers concluded modular CTOs showed worse performance compared with their standard counterpart, the Aspen CTO, whereas adjustable COs showed performance comparable to their standard counterpart, the Aspen collar. – by Robert Linnehan
