A 10-Week Program of Combined Hippotherapy and Scroth’s Exercises Improves Balance and Postural Asymmetries in Adolescence Idiopathic Scoliosis: A Randomized Controlled Study

Introduction: The most frequent type of spine abnormality throughout adolescence was adolescent idiopathic scoliosis (AIS). Hippotherapy improved posture, balance and gait of different musculoskeletal conditions. Therefore, this study aims to see how hippotherapy combined with Schroth exercises affected postural asymmetry and dynamic balance in AIS compared to traditional physiotherapy (Schroth exercises) alone. Materials and methods: In this randomized controlled trial, fifty-two patients with AIS (10–18 years, 37 girls and 15 boys) participated. They were arbitrarily allocated into two groups: experimental (19 female/8 male; aged 14.74 ± 1.79 years; Cobb angle 18.59 ± 2.66 degrees) and control (18 female/7 male; aged 15.04 ± 1.81 years; Cobb angle 19.32 ± 2.69 degrees) groups. Both groups received Schroth exercises for 10 weeks, three days/week. The experimental group additionally received hippotherapy training. Pre-treatment and post-treatment assessment for the scoliotic, kyphotic angle, pelvic obliquity, pelvic torsion and vertical spinal rotation and the anteroposterior, mediolateral and overall stability indices were assessed using the formetric system 4D and Biodex Balance System, respectively. Results: After intervention, both groups illustrated significant improvements in all examined variables (p < 0.05). The experimental group illustrated significant improvements in scoliotic angle, kyphotic angle, pelvic obliquity, pelvic torsion and vertical spinal rotation and the stability indices compared to the control group (p < 0.05). Conclusion: In adolescence idiopathic scoliosis, hippotherapy training combined with Schroth exercises improves posture asymmetry and balancing ability more effectively than Schroth exercises alone.

Temperature Distribution of Selected Body Surfaces in Scoliosis Based on Static Infrared Thermography

The purpose of the research was to assess the usefulness of thermography as a complementary method in musculoskeletal dysfunction, with particular emphasis on scoliosis. The children, aged 7–16, were classified into one of two groups: the study group—children with scoliosis (n = 20), and the reference group—healthy children (n = 20). All children underwent anthropometric tests, body mass index determination, four pictures each with a FLIR T1030sc HD thermal imaging camera, and measurement of spinal rotation with a scoliometer (Gima, Italy). There is a temperature differential (about 4 °C) within the upper and lower body in children. In healthy children, differences in temperature of contralateral areas of the body do not exceed 0.5 °C. Thermography is a useful and noninvasive method of assessing muscular tension disbalance in the course of scoliosis. In the case of scoliosis, the areas of the body with a significant thermal asymmetry of the surface are the upper back, thighs, and back of the lower legs. Due to the high positive correlation of the spinal rotation angle with the amount of thermal asymmetry, the areas that should be subjected to a detailed thermal assessment in the supplementary diagnosis of scoliosis using thermovision are the upper back, chest, thighs, and back of the lower legs.

The effects of rotation on radiological parameters in the spine

Background Vertebral rotation in straight spines or in spines with small scoliosis may potentially affect measurement of radiological parameters in both the frontal and sagittal plane. This is important, since it could lead to potential misdiagnosis of scoliosis and other clinical consequences, and until now, this has not been examined. Purpose To examine the effect of axial vertebral rotation of the spine on measurement of common radiological parameters. Material and Methods Reconstructions from computed tomography scans of 40 consecutive included and anonymized patients with straight spines or small scoliosis. Fourteen sagittal and coronal reconstructions covering the whole pelvis and spine were executed. Radiographic parameters in both the frontal and sagittal plane were measured blinded and separately by three doctors. These parameters were evaluated for inter-rater reliability using intraclass correlation coefficient and mixed model analysis for the effects of rotation. The parameters were also analyzed sub-stratified according to “Lenke's classification” and 15 sub-categories of thoracic and lumbar Cobb's angle (CA). Results Vertebral rotation in general does not have any significant effects in both the frontal and sagittal plane. However, there are significant effects on CA and spinopelvic radiologic parameters in extreme rotation or for larger scoliosis. Inter-rater reliability was very good to good. Conclusion In conclusion, axial spinal rotation does not influence common radiological parameters in the frontal and sagittal plane, except in cases of extreme rotation or large scoliosis for selected parameters; thus, this does not lead to potential misinterpretation in scoliosis diagnosis, treatment, or research.

THREE-DIMENSIONAL GAIT ANALYSIS AS A POTENTIAL AND QUANTIFIABLE MEASUREMENT IN THE CLINICAL EVALUATION OF ANKYLOSING SPONDYLITIS

The present study aimed to investigate the potential clinical value of three-dimensional gait analysis (3D-GA) system in evaluating ankylosing spondylitis (AS). Thirty-one patients with AS from September 2010 to August 2011, with 32 involved and 30 uninvolved lower limbs, were enrolled. Data of spatio-temporal parameters (step and stride length, velocity and cadence), time parameters (stance, single stance, double stance and swing phases) and kinematics parameters associated with spinal mobility (spinal lateral bending, spinal forward bending and spinal rotation) were analyzed by 3D-GA system, as well as curative effects of biologic therapy. Compared with normal values, AS patients showed decreased step and stride length ([Formula: see text]), increased cadence, longer swing and single stance phases ([Formula: see text]) and shorter stance and double stance phases ([Formula: see text]) in uninvolved lower limbs. In AS patients, reduced step length, stride length, velocity and cadence, shorter swing and single stance phases, longer stance and double stance phases ([Formula: see text]), increased lateral bending angle and decreased spinal rotation ([Formula: see text]) were detected by 3D-GA in involved lower limbs compared with uninvolved ones. In the 16 patients with decreased levels of ESR and CRP and improved ASAS scores after biology therapy, increased step length, stride length, velocity and cadence of the involved lower limbs were detected by 3D-GA ([Formula: see text]), as well as improved spinal mobility ([Formula: see text]). Hence, we concluded that 3D-GA has great potential value of clinical application for assessing and monitoring AS.

In-vitro Kinematic Testing of Porcine Cervical Spine: A Rotational Manipulation Model

Although spinal manipulation is widely used in the management of neck and pain, its exact mechanisms and biomechancial effects are not clear. A porcine model was used to study the relative movements of intervertebral joints under spinal rotation maneuvers with different input angular displacements and thrust velocities. Ten porcine spines (C2/4) were fixed and mounted in a material testing machine. Rotational maneuvers with different input angular displacements (0.8, 1.5, 2 and 3°) and thrust velocities (0.1 – 200°/s) were applied to C2 with C4 fixed. Angular displacement induced at the adjacent level was measured and expressed as percentage of the applied angular displacement. For all the tested conditions, angular deformation at the adjacent level could not be avoided when an angular thrust was applied to the target level. The percentage of the angular displacement induced at the adjacent level was found to be dependent on both the input angular displacement and thrust velocity. If rapid thurst of manipulation is used to direct the input energy and motion at the target level with minimal interference at the adjacent levels, the applied angular displacement should not be too large and the thrust velocity should be within a medium velocity range.
