Information on the therapeutic value of S-shaped scoliosis rehabilitation. Material. The study focused on one subject of 21 years old, diagnosed with dorso-lumbar scoliosis, lumbar spine rotated in the axis and asymmetrical pelvis; the patient has been complaining of pains in the lumbar area for more than a year. The tests and procedures used: measurement with the plumb line, Adam's forward bend test; circling of spinal apophyses; thoracic and hemithoracic perimeters; drawing of scapular and pelvic anatomical reference points; drawing of the Rhombus of Michaelis; measuring of leg length; examination of spine mobility (articular examination, muscular examination) and radiography. Results. Highlighting the changes in the thoracic perimeters indicators and the differences of the right lower limb length as a result of the asymmetrical global deformation entailed by the changes of spine curves. Determination of the scoliosis severity by comparing the vertical line of left thoracic distance and right lumbar distance with the normal values. Increase of spine mobility at cervical and dorso-lumbar level, improvement of muscle deficiency and elimination of pain in lumbar area. Conclusions. By early application of the specific and non-specific kinetic means and observance of the principles of effort progressivity and treatment individualization, very good results are obtained, which confirm the proposed hypothesis.

“…In this method, reconstruction was performed, and the complete spine data were projected to obtain the coronal image. It was reported that the FUPI can greatly decrease the processing time (15.07 ± 0.03 s for FUPI vs. 130.31 ± 35.07 s for the conventional method) 28 . However, this method is still an off‐line imaging method and cannot be used in a situation where immediate feedback is needed.…”

Real‐time 3D ultrasound has gained popularity in many fields because it can provide interactive feedback to help acquire high‐quality images or to conduct timely diagnosis. However, no comprehensive study has been reported on such an imaging method for scoliosis evaluation due to the complexity of this application. Meanwhile, the use of radiation‐free assessment of scoliosis is becoming increasingly popular. This study developed a real‐time 3D ultrasound imaging method for scoliosis assessment based on an incremental imaging method. In vivo experiments involving 36 patients with scoliosis were performed to test the performance of the proposed method. This new imaging method achieved a mean incremental frame rate of 82.7 ± 11.0 frames/s. The high repeatability of the intra‐operator test (intraclass correlation coefficient [ICC] = 0.92) and inter‐operator test (ICC = 0.91) demonstrated that the new method was very reliable. The result of spinous process angles obtained by the new method was linearly correlated (y = 0.97x, R2 = 0.88) with that obtained by conventional 3D reconstruction. These results suggested that the newly developed imaging method can provide real‐time ultrasound imaging for scoliosis evaluation while preserving the comparative image quality of the conventional 3D reconstruction method.

“…With a non‐planar re‐slicing approach, where the skin surface is the reference for a slicing plane, the VPI method obtains an averaged intensity of all voxels of the volumetric image at a specified depth to form an image in the coronal plane. Jiang et al., 10 developed a 9‐times faster coronal image generation approach than original VPI method by skipping the unnecessary 3D reconstruction and directly mapping the B‐mode images and their corresponding positional data. Another method suggested by Vo et al., 11 creates the 3D spine reconstruction compounded from segmented bony features, which allows them to choose the plane of maximum curvature for coronal image projection.…”

Background Ultrasound (US) imaging for scoliosis assessment is challenging for a non‐experienced operator. The robotic scanning was developed to follow a spinal curvature with deep learning and apply consistent forces to the patient's back. Methods Twenty three scoliosis patients were scanned with US device both, robotically and manually. Two human raters measured each subject's spinous process angles on robotic and manual coronal images. Results The robotic method showed high intra‐ (ICC > 0.85) and inter‐rater (ICC > 0.77) reliabilities. Compared with the manual method, the robotic approach showed no significant difference (p < 0.05) when measuring coronal deformity angles. The mean absolute deviation for intra‐rater analysis lies within an acceptable range from 0 to 5° for the minimum of 86% and maximum 97% of a total number of the measured angles. Conclusions This study demonstrated that scoliosis deformity angles measured on ultrasound images obtained with robotic scanning are comparable to those obtained by manual scanning.
