A Tool to Estimate Risk of 30-day Mortality and Complications After Hip Fracture Surgery: Accurate Enough for Some but Not All Purposes? A Study From the ACS-NSQIP Database
CONCLUSION: The models of mortality and complications we developed may be accurate enough for some uses, especially personalizing informed consent and shared decision-making with patient-specific risk estimates. However, the high false discovery rate suggests the models should not be used to restrict access to surgery for high-risk patients. Deciding which measures of accuracy to prioritize and what is "accurate enough" depends on the clinical question and use of the predictions. Discrimination and calibration are commonly used measures of overall model accuracy but may be poorly suited to certain clinical questions and ap...

Myoelectric Elbow-Wrist-Hand Orthosis for an Adolescent with Hemiparesis: A Case Report
Discussion This case report presents insights on why the patient was not as proficient and interested in using the orthosis at home and school. Recommendations to address these issues include peer modeling, community outings, early intervention, and the use of family-centered approaches. Future studies are also suggested to further understand MEWHO use and the considerations for successful orthotic management in this group of patients.

Early and ultra-early surgical decompression for acute spinal cord injury: bracing for the winds of change
ConclusionThis is a call for hospital systems to swiftly restructure spinal services in order to meet the need for early, and possibly ultra-early, spinal decompression in aSCI cases in the near future.

Machine learning-driven identification of novel patient factors for prediction of major complications after posterior cervical spinal fusion
ConclusionWe report an ensemble ML model for prediction of major complications and readmission after posterior cervical fusion with a modest risk prediction advantage compared to LR and benchmark ML models. Notably, the features most important to the ensemble are markedly different from those for LR, suggesting that advanced ML methods may identify novel prognostic factors for adverse outcomes after posterior cervical fusion.

Slacklining and stroke: A rehabilitation case study considering balance and lower limb weakness.
Authors: Gabel CP, Rando N, Melloh M Abstract To ascertain the effectiveness of slacklining as a supplementary therapy for elderly stroke patients who are functionally non-progressing. This case study involved an 18-mo prospective observation of the management of an 87-year-old female stroke-patient of the left hemisphere with reduced balance, reduced lower limb muscular activation, hypertonia, and concurrent postural deficits. This entailed the initial acute care phase through to discharge to home and 18-mo final status in her original independent living setting. The introduction of slacklining as an adjunct thera...

The use of a planar and simple robotic device to investigate how chronic stroke patients learn a movement
Introduction: The ability of chronic stroke patients to learn a new movement is not well known in literature yet. A way to investigate motor outcome after rehabilitation is to use robotic devices that allow the objective and repeatable assessment of the acquired movement.

Modelling the recovery of acute stroke survivors during adaptive robot-assisted training
In this study, the analysis of the trial-by-trial performance highlighted three main aspects of the recovery process: learning, retention, and slacking.

Reaching tasks in an altered dynamic environment: Motor adaptation in FRDA patients
Introduction: In the last few years, robotic devices are extensively employed to exploit how the Central Nervous System (CNS) learns to control movements in different dynamical conditions. It was demonstrate that normally developed subjects can adapt to novel dynamic environments, tuning an internal model of the arm environment to compensate systematically applied forces, and showing an after-effect that appears when the force field is unexpectedly removed [1]. It was also found that this capability is at least partially still present in subjects affected by Huntington's disease, or in stroke survivor, but not in subjects ...
