Summary: The reliability and validity of the WitMotion sensor device in evaluating cervical proprioception were analyzed in this study, and a cheaper, more convenient, and more practical testing tool was explored. The results showed that the intra- and inter-rater reliability of the WS device were higher than that of the LPD for certain cervical movements, while the LPD showed higher reliability for other movements. The validity of both the WS device and LPD in measuring joint position error was moderate to good.

Summary: In this study, we investigate the dynamics of one-dimensional and two-dimensional solitons in chiral magnetic materials and propose an elastic restorative force model to explain skyrmion deformations. The results show that the deformations of skyrmions are related to local imbalances of gyrotropic forces, and the limits on skyrmion compactness impede their ability to reach the velocity regime where relativistic effects occur.

Summary: This study developed a comprehensive score system (CSS) that considers clinical, neurophysiological, and neuroradiological data to predict outcome in patients with cervical spondylotic myelopathy undergoing surgery. The CSS model showed good accuracy in predicting outcomes and supporting surgeons' decisions for surgery candidates.

Summary: This paper proposes a new finger motion detection method based on optical fiber Bragg grating (FBG) with polyimide substrate, which monitors the deformation around the forearm caused by finger motion. Through tests, it is verified that FBG with polyimide substrate has good response characteristics and applicability. The experimental results show that this method can effectively detect static gestures and has good repeatability.

Summary: This multicenter prospective study aimed to investigate the impact of ossification spread on cervical spine function and quality of life in patients with cervical OPLL. The study found that a higher neck VAS score and a larger number of bridge formations of OPLL in the whole spine were significant predictors of adverse outcomes related to cervical spine function.

Summary: Introducing the shape anisotropy of a skyrmion is an alternative strategy for controlling the skyrmion Hall effect. An elliptical skyrmion shows anisotropic motion under the applied driving force. The study of an elliptical skyrmion induced by uniaxial in-plane magnetic anisotropy reveals that the skyrmion Hall angle can reach 90° with optimized parameters.

Summary: The proposed sensor utilizes magnetic elastomer material deformation and changes in magnetic field amplitude and direction for measurements. The sensor design is simple and reliable, suitable for a wide range of rotational speeds. Components of the sensor structure include magnetic elastomer coating, magneto-resistive linear field sensor, and microprocessor unit for calibration and control.

Summary: This study compared the radiologic outcomes and alignment changes of different fusion devices in the treatment of cervical spondylotic myelopathy. The results showed that the use of the Zero-profile (ZP) device had a lower rate of postoperative dysphagia and adjacent segment disease (ASD) compared to the cage-plate (CP) construct in anterior cervical diskectomy and fusion (ACDF). However, as the last follow-up time increased, the ZP group showed greater changes in cervical alignment.

Summary: This study investigated the length of hospital stay required for ADL recovery in patients undergoing two-stage corrective fusion surgery for ASD. Factors such as age, estimated glomerular filtration rate, age-adjusted Charlson comorbidity index, and preoperative pelvic incidence were found to be associated with the length of hospital stay. In conclusion, after >50 days, patients' ADL performance reached the level needed to return home, with age and frailty-related indices being the main factors affecting the length of hospital stay.

Summary: The study showed that concomitant foraminotomy in cervical laminoplasty increases the incidence of upper limb palsy, potentially due to thermal nerve damage. Patients in the foraminotomy group also had a higher proportion of preoperative upper-limb muscle weakness and were more likely to experience early-onset upper limb palsy postoperatively.

Summary: This study compared the short-term radiographical and clinical outcomes of posterior lumbar interbody fusion with different types of cages. The results showed that at 6 months postoperatively, patients with a three-dimensional porous titanium alloy cage had lower rates of vertebral endplate cyst formation and cage subsidence compared to those with a titanium-coated poly-ether-ether-ketone cage. However, there were no differences in fusion rates and surgery effectiveness between the two groups at both 6 months and 1 year postoperatively.
