BackgroundConservative treatment in the adolescent idiopathic scoliosis (AIS) population is based on individual proprioceptive and motor control training. Such training includes physiotherapeutic scoliosis-specific exercises (PSSEs) stimulating the individual capacity to perceive and control his/her posture, particularly the shape of the spine. However, limited knowledge about basic proprioception capability in AIS patients is reported in the literature.Questions(1) How do AIS patients, who did not receive any previous specific postural education treatment, perceive their posture and 3D spine shape? Are they able to modify their posture and 3D spine shape correctly through an instinctive self-correction (ISCO) maneuver? (2) Are posture and ISCO maneuver ability gender dependent in AIS patients? (3) Do AIS patients present different posture and spine shape characteristics as well as different ISCO ability compared with the healthy young adult population?MethodsCross-sectional observational study. 132 (75 females, 57 males) AIS patients’ posture and 3D spine shape have been measured comparing indifferent orthostasis (IO) (neutral erect posture) to ISCO using a non-ionizing 3D optoelectronic stereophotogrammetric approach. Thirteen quantitative biomechanical parameters described the AIS patients body posture. The statistical analysis was performed using a multivariate approach to compare genders in IO, ISCO, and AIS patients vs. healthy young adults–previously published data (57 females, 64 males).ResultsMales (87.7%) and females (93.3%) of AIS patients were unable to modify posture and 3D spine shape globally. AIS patients gender differences were found in IO, ISCO, and the comparison vs. healthy young adults. When changes occurred, subjects could not focus and control their posture globally, but only in a few aspects at a time.ConclusionSelf-correction maneuver producing an improvement in body posture and spine shape is not instinctive and must be trained. In such characteristics, AIS patients are not so dissimilar to healthy young adults. Sagittal plane control is the highest, but ISCO in AIS patients led to worsening in this plane. Control at the lumbar level is neglected in both genders. Such outcomes support the necessity of customized PSSEs to treat AIS patients. The 3D stereo-photogrammetric approach is effective in quantitatively describing the subject’s posture, motor control, and proprioception.

Abstract Background: This study aims to evaluate the effects of bracing on the Cobb’s angle (CA) and spinopelvic parameters in adolescent idiopathic scoliosis (AIS) patients. Methods: A total of 51 AIS patients who received bracing treatment between January 2018 and August 2019 were retrospectively analyzed. The pro-bracing and in-bracing radiographs were analyzed with regard to the spinopelvic parameters. The CA, pelvic coronal obliquity angle (PCOA), thoracolumbar kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), sagittal vertical angle (SVA) and coronal vertical angle (CVA) were measured. Results: The mean age at the initiation of bracing was 13.6 ± 1.5 years. The mean pro-bracing CA was 24.0° ± 6.3°. There were no statistically significant differences between pro-bracing and in-bracing measurements of SVA and CVA. However, there were statistically significant differences between the pro-bracing and in-bracing measurements of the CA, PCOA, TLK, LL, PT and SS. A significant correlation was observed between PT variation and TLK variation in the sagittal plane. In the coronal plane, the PCOA variation was correlated to pro-bracing PCOA. Conclusion: Bracing effects of AIS can be extended to the pelvis. The pelvis should retro-rotate correspondingly to TLK hypokyphosis on sagittal plane, whereas in coronal plane, pelvic obliquity was improved independently.

Abstract BackgroundAlthough Lenke classification analyses the sagittal plane as (+), N, and (-), it does not consider it in the choice of treatment, and it has limitations with overall thoracic kyphosis (TK). To investigate the importance of TK for treatment preference in patients with Lenke 5C adolescent idiopathic scoliosis (AIS) by comparing radiological outcomes of the patients who underwent selective fusion (SF) or nonselective fusion (NSF). MethodsThirty-two patients with Lenke type 5C AIS were included and then divided into two groups as per the fusion procedure used in the surgical treatment. SF group including 17 patients (15 females; mean age = 16 years, age range, 14–21) with normal TK and NSF group including 15 patients (11 females; mean age = 17 years, age range, 13–26) with thoracic hyper-kyphosis. Thorocolumbar/lumbar (TL/L) Cobb, thoracic (T) Cobb, TK and lumbar lordosis (LL) were measured on standing spine radiographs preoperatively and at the final follow-up. The correction rates (CR) of each radiographic parameter were calculated.ResultsNo significant differences were observed in the mean CR of all radiographic parameters, except TK and LL correction rates. The mean CR of TK was significantly higher in NSF group (-17% [range, -100–69]) than in SF group (67% [range, 9–100]) (p = 0.000). Likewise, the mean CR of LL was found significantly higher in NSF group (12.47% [range, -100–51]) than in SF group (-2.41% [range, -75–47]) (p = 0.036).ConclusionIn patients in whom Lenke's sagittal modifier is N, SF can be performed efficiently. NSF should be preferred in those with Lenke's sagittal modifiers (+) as TK can be better controlled with NSF.Level of Evidence: 3

This paper describes the design and control architecture of a novel Wheelchair-mounted Robot for Active Postural Support (WRAPS). The WRAPS is a robotic exoskeleton that allows limited degrees-of-freedom (DOFs) of the trunk relative to the pelvis. There are three DOFs in the sagittal plane of the human body and one in lateral bending. The work is motivated by the needs of individuals with impaired trunk motor control, who currently rely on the use of passive and predominantly static supports to maintain a static posture. These devices can be overly restrictive and inhibit the user in their activities of daily living (ADLs). The WRAPS is capable of supporting a human user within their active range of torso motion. It has the potential to assist users in their ADLs while encouraging a dynamic range of healthy postures.
