PURPOSE: This study aimed to improve the effectiveness of orthotic treatment for the patients with AIS using the three-dimensional clinical ultrasound (3D CUS) method in which the optimal location of pressure pad of spinal orthosis was determined with the assistance of ultrasound image analysis.
METHODS: By means of 3D CUS method, the spinous process angle (SPA) could be traced and used as a clinical parameter to estimate the Cobb's angle in order to determine the location of pressure pad. Twenty-one patients (test group) and 22 patients (control group) were recruited to the ultrasound-assisted fitting method and the conventional fitting method, respectively. All the measurements were done by a blinded observer.
RESULTS: The intra-rater reliability of using 3D CUS to measure SPA was found >0.9 [ICC (3,3) = 0.91, p < 0.05]. In the test group, 13 out of 21 patients were required to adjust the location of pressure pad in order to achieve the largest curvature correction. The mean immediate in-brace corrections (Cobb's angle measured from radiographs) of the test group (mean thoracic curve correction: 10.3°, mean lumbar curve correction: 10.1°) were found significantly higher (p < 0.005) than that of the control group (mean thoracic curve correction: 4.6°, mean lumbar curve correction: 6.0°). The results showed that the ultrasound-assisted fitting method of spinal orthosis was effective and beneficial to 62 % of the patients in this study.
CONCLUSIONS: The 3D CUS could be considered as an effective, non-invasive and fast assessment method to scoliosis, especially in enhancing the effectiveness of orthotic treatment and its applications could also be further extended to other spinal deformities.
