Real-time ultrasound image classification for spine anesthesia using local directional Hadamard features.
Injection therapy is a commonly used solution for back pain management. This procedure typically involves percutaneous insertion of a needle between or around the vertebrae, to deliver anesthetics near nerve bundles. Most frequently, spinal injections are performed either blindly using palpation or under the guidance of fluoroscopy or computed tomography. Recently, due to the drawbacks of the ionizing radiation of such imaging modalities, there has been a growing interest in using ultrasound imaging as an alternative. However, the complex spinal anatomy with different wave-like structures, affected by speckle noise, makes the accurate identification of the appropriate injection plane difficult. The aim of this study was to propose an automated system that can identify the optimal plane for epidural steroid injections and facet joint injections. ⋯ A real-time machine learning system based on the local directional Hadamard features extracted by the sequency-ordered Hadamard transform for detecting the laminae and facet joints in ultrasound images has been proposed. The system has the potential to assist the anesthesiologists in quickly finding the target plane for epidural steroid injections and facet joint injections.

Women wearing high-heeled shoes have been considered to be more characterizing beauty, self-assurance and elegance. However, while maintaining the body on this type of support base, women with increased heel height often complain that wearing high-heeled shoes causes them to experience low back pain. The aim of the present study was to morphologically assess the effect of high-heel use on the static sagittal profile of the spino-pelvic structure. ⋯ The present study revealed that wearing high-heeled shoes can lead to increased LL and an uneconomic body position. This finding may help explain why some women complain that wearing high-heeled shoes causes them to experience low back pain.

OBJECT Patient satisfaction scores have become a common metric for health care quality. Because satisfaction scores are right-skewed, even small differences in mean scores can have a large impact. Little information, however, is available on the specific factors that play a role in satisfaction in patients with spinal disorders. ⋯ Composite satisfaction scores were lower among patients who had severe disability than among those with mild to moderate disability (median [interquartile range]: 91.7 [83.7-96.4] vs 95.8 [91.0-99.3], respectively; p = 0.0040). Patients who received a recommendation against surgery reported lower satisfaction scores than those who received a recommendation for surgery (91.7 [83.5-95.8] vs 95.8 [88.5-99.8]; p = 0.0059). CONCLUSIONS High self-assessment of disability and a surgeon's recommendation against surgical intervention are associated with lower satisfaction scores in patients with spinal disorders.

Randomized Controlled Trial Multicenter Study Comparative StudyThe effect of changing movement and posture using motion-sensor biofeedback, versus guidelines-based care, on the clinical outcomes of people with sub-acute or chronic low back pain-a multicentre, cluster-randomised, placebo-controlled, pilot trial.
The aims of this pilot trial were to (i) test the hypothesis that modifying patterns of painful lumbo-pelvic movement using motion-sensor biofeedback in people with low back pain would lead to reduced pain and activity limitation compared with guidelines-based care, and (ii) facilitate sample size calculations for a fully powered trial. ⋯ Individualised movement retraining using motion-sensor biofeedback resulted in significant and sustained improvements in pain and activity limitation that persisted after treatment finished. This pilot trial also refined the procedures and sample size requirements for a fully powered RCT. This trial (Australian New Zealand Clinical Trials Registry NCT01572779) was equally funded by dorsaVi P/L and the Victorian State Government.
