“…Depending on the severity of the impairment, activities of daily life (ADL) such as personal hygiene or food intake can not be performed without help. Reasons for a loss of motor function range from neuropathological conditions such as stroke to traumatic brain or spinal cord injury (SCI) [1,2]. Especially for persons with a traumatic SCI at the cervical level, circumstances turn out to be life-changing, since not only lower extremities and autonomic body functions are affected, but also upper extremity functions namely reaching and grasping.…”

Objective: Chronic motor impairments of arms and hands as the consequence of acervical spinal cord injury (SCI) have a tremendous impact on activities of daily life.A considerable number of people however retain minimal voluntary motor control in theparalyzed parts of the upper limbs that are measurable by electromyography (EMG)and inertial measurement units (IMUs). An integration into human-machine interfaces(HMIs) holds promise for reliable grasp intent detection and intuitive assistive devicecontrol.Approach: We used a multimodal HMI incorporating EMG and IMU data to decodereach-and-grasp movements of groups of persons with cervical SCI (n=4) and without(control, n=13). A post-hoc evaluation of control group data aimed to identify optimalparameters for online, co-adaptive closed-loop HMI sessions with persons with cervicalSCI. We compared the performance of real-time, Random Forest-based movementversus rest (2 classes) and grasp type predictors (3 classes) with respect to their coadaptationand evaluated the underlying feature importance maps.Main results: Our multimodal approach enabled grasp decoding significantly betterthan EMG or IMU data alone (p<0.05). We found the 0.25 s directly prior to the firsttouch of an object to hold the most discriminative information. Our HMIs correctlypredicted 79.3 ± STD 7.4 (102.7 ± STD 2.3 control group) out of 105 trials withgrand average movement vs. rest prediction accuracies above 99.64% (100% sensitivity)and grasp prediction accuracies of 75.39 ± STD 13.77% (97.66 ± STD 5.48% controlgroup). Co-adaption led to higher prediction accuracies with time, and we couldidentify adaptions in feature importances unique to each participant with cervicalSCI.Significance: Our findings foster the development of multimodal and adaptive HMIsto allow persons with cervical SCI the intuitive control of assistive devices to improvepersonal independence.

“…Spinal Cord Injuries (SCIs) represent a global health challenge with far-reaching consequences for affected individuals and healthcare systems. Worldwide, it is estimated that between 250,000 and 500,000 people suffer from SCIs annually, as reported by the World Health Organization (WHO) [1]. These injuries, stemming from traumatic incidents like motor vehicle accidents and falls, necessitate effective prehospital management strategies to minimize long-term disability and optimize patient outcomes [2,3].…”

Introduction: Despite the critical role of prehospital management, variations persist in global practices. Recent literature indicates that about 35% of emergency medical services (EMS) providers adhere to established guidelines for spinal immobilization in certain regions. This systematic review aimed to contribute to the ongoing dialogue surrounding the prehospital management of SCIs, ultimately improving outcomes for individuals affected by these traumatic injuries. Methods: A comprehensive literature review was conducted through a systematic search of electronic databases, employing refined search terms and Boolean operators to focus on prehospital management of spinal cord injuries from the inception of each database to July 2023. Inclusion criteria involved original research articles, systematic reviews, and meta-analyses, with a screening process led by two independent reviewers and subsequent data extraction to inform evidence synthesis, accounting for study limitations and bias assessments. Results: This systematic review summarizes findings from eight clinical interventional studies on preventing idiopathic spinal cord injury (SCI) during prehospital emergency aid for traumatized patients. The studies encompassed diverse populations and interventions, revealing variable effectiveness in reducing idiopathic SCI incidence. Notably, specialized protocols for pediatric spinal immobilization and modifications for geriatric patients demonstrated promising effectiveness, emphasizing the importance of age-specific considerations in prehospital care for SCI prevention. Conclusions: The systematic review findings underscore the nuanced nature of prehospital interventions for idiopathic spinal cord injury prevention, emphasizing the importance of age-specific considerations and cautioning against a one-size-fits-all approach, while also highlighting the need for ongoing research to refine protocols and improve patient outcomes given the lack of definitive evidence in favor of early versus delayed immobilization.
