Abstract Background and Purpose. The purpose of this study was to compare the cough threshold between people with and without spinal cord injury (SCI). The effect of smoking on cough threshold was also investigated. Subjects. The participants were 26 people with SCI (15 smokers, 11 nonsmokers) and 18 people without SCI (9 smokers, 9 nonsmokers). Methods. Aerosols of citric acid were delivered with incremental doubling concentration from 62.5 mmol to 2 mol. Cough threshold was defined as the first concentration of citric acid that induced at least 2 coughs, which is associated with large chest excursion and concurrently acoustic response. Results. The mean cough thresholds of smokers and nonsmokers with SCI (209 and 417 mmol, respectively) were lower than those of smokers and nonsmokers without SCI (467 and 1,072 mmol, respectively). The mean citric acid cough thresholds decreased in smokers with and without SCI when compared with nonsmokers with and without SCI. Conclusion and Discussion. The cough sensitivity increased in subjects with SCI, and smoking could also increase the cough sensitivity. Training about the frequency and technique of cough in patients with SCI should be carefully monitored.

Abstract The records of 123 consecutive patients admitted with spinal cord injury were examined for the presence of pulmonary complications. Forty-nine had tetraplegia and 23 had paraplegia; the remainder suffered a variety of neurological deficits. Multiple injuries were encountered in 36 patients. Fifty-three pulmonary complications were noted in 44 (35.7%) patients. The most common problems were atelectasis and pneumonia. There were 22 (18%) deaths. Fourteen deaths were related to pulmonary complications. The mean age of patients who died was 52 ± 13 (SE) compared to 28 ± 12 for survivors. A mean forced vital capacity (FVC) of 1127 ± 410 cc in patients suffering respiratory difficulties compared to a FVC of 1865 ± 85 cc in patients without complications (P < 0.001). Oxygenation (PaO2 90 ± 19 torr) was normal in patients without respiratory problems and was abnormal in patients developing problems (PaO2 76 ± 30 torr; P < 0.05). Twenty patients were treated with a rotating bed. The complication rate of patients on the bed was only 10%. In conclusion, respiratory problems remain a significant cause of morbidity and mortality in spinal cord injury. The forced vital capacity, blood oxygen tension, and age are predictors of pulmonary complications. The use of a multidisciplinary approach and a rotating bed may minimize these problems.

Epidemiological Characteristics

Abstract Background: Traumatic spinal cord injury (SCI) is recognized as a serious public health problem resulting in significant morbidity, mortality and permanent disability. The present study is aimed to describe the epidemiological characteristics and outcome of patients with traumatic spinal cord injury in rural tertiary referral care center form South India. Material and methods: The present study was conducted at Narayana Medical College and Hospital, Nellore. All patients admitted and managed for traumatic spinal cord injury were retrieved and data collected in a pre-designed proforma. Patient characteristics, details of etiology, mechanism of injury, level of injury, extent of neurological deficits, details of investigations, details of management and immediate outcome were recorded. Results: A total 152 patients were included in the present study. The mean age was 38.45 years and majority the patients were young adult males. The mean hospital stay was 19.12 days. 71.7% percent patients were non-agriculture workers (mainly involved in construction work) and 28.3% patients were farmers. 61.2% of the patients sustained injuries due to fall from height and 34.2% patients sustained injuries due road traffic accidents. Cervical spine injuries were most common (44.1%), followed by thoraco-lumbar region (36.8%) and dorsal spinal region (19.1%). 9 patients expired in post-injury during hospital stay and all of them had complete cervical spinal cord injury. All patients received aggressive rehabilitation care. Conclusion: In accordance with the literature our results reflect that traumatic spinal cord injuries affect young population and can leave these persons with significant functional and physical morbidity. The major limitation of the study is that it is a single institution based and may not reflect the true spectrum of traumatic spinal cord injuries in the population.

Motility impairments resulting from spinal cord injuries and cerebrovascular accidents are increasingly prevalent in society, leading to the growing development of rehabilitative robotic technologies, among them exoskeletons. This article outlines how bodies with neurological conditions such as spinal cord injury and stroke engage in processes of re-appropriation while using exoskeletons and some of the challenges they face. The main task of exoskeletons in rehabilitative environments is either to rehabilitate or ameliorate anatomic functions of impaired bodies. In these complex processes, they also play a crucial role in recasting specific corporeal phenomenologies. For the accomplishment of these forms of corporeal re-appropriation, the role of experts is crucial. This article explores how categories such as bodily resistance, techno-inter-corporeal co-production of bodies and machines, as well as body work mark the landscape of these contemporary forms of impaired corporeality. While defending corporeal extension rather than incorporation, I argue against the figure of the ‘cyborg’ and posit the idea of ‘residual subjectivity’.

✓ Hypocarbia, normocarbia, or hypercarbia was maintained for an 8-hour period beginning 30 minutes after acute threshold spinal cord injuries in cats. No statistically significant differences in neurological recovery or histologically assessed tissue preservation were found among the three groups of animals 6 weeks after injury. No animal recovered the ability to walk. It is concluded that maintenance of hypercarbia or hypocarbia during the early postinjury period is no more therapeutic than maintenance of normocarbia. Mortality rates and tissue preservation data suggest, however, that postinjury hypocarbia may be less damaging than hypercarbia.

OBJECTIVEGranulocyte-colony stimulating factor (G-CSF) is a major cytokine that has already been clinically verified for chronic traumatic spinal cord injuries (TSCIs). In this study, the authors set out to determine the safety and efficacy of G-CSF administration for neurological and functional improvement in subacute, incomplete TSCI.METHODSThis phase II/III, prospective, double-blind, placebo-controlled, parallel randomized clinical trial was performed in 60 eligible patients (30 treatment, 30 placebo). Patients with incomplete subacute TSCIs with American Spinal Injury Association Impairment Scale (AIS) grades B, C, and D were enrolled. Patients were assessed using the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) scale, Spinal Cord Independence Measure (SCIM-III) and International Association of Neurorestoratology Spinal Cord Injury Functional Rating Scale (IANR-SCIFRS), just before intervention and at 1, 3, and 6 months, after 7 daily subcutaneous administrations of 300 μg/day of G-CSF in the treatment group and placebo in the control group.RESULTSAmong 60 participants, 28 patients (93.3%) in the G-CSF group and 26 patients (86.6%) in the placebo group completed the study protocol. After 6 months of follow-up, the AIS grade remained unchanged in the placebo group, while in the G-CSF group 5 patients (45.5%) improved from AIS grade B to C, 5 (45.5%) improved from AIS grade C to grade D, and 1 patient (16.7%) improved from AIS grade D to E. The mean ± SEM change in ISNCSCI motor score in the G-CSF group was 14.9 ± 2.6 points, which was significantly greater than in the placebo group (1.4 ± 0.34 points, p < 0.001). The mean ± SEM light-touch and pinprick sensory scores improved by 8.8 ± 1.9 and 10.7 ± 2.6 points in the G-CSF group, while those in the placebo group improved by 2.5 ± 0.60 and 1.2 ± 0.40 points, (p = 0.005 and 0.002, respectively). Evaluation of functional improvement according to the IANR-SCIFRS instrument revealed significantly more functional improvement in the G-CSF group (10.3 ± 1.3 points than in the placebo group (3.0 ± 0.81 points; p < 0.001). A significant difference was also observed between the 2 groups as measured by the SCIM-III instrument (29.6 ± 4.1 vs 10.3 ± 2.2, p < 0.001).CONCLUSIONSIncomplete subacute TSCI is associated with significant motor, sensory, and functional improvement after administration of G-CSF.Clinical trial registration no.: IRCT201407177441N3 (www.irct.ir)

Background: Spinal cord injury is one of the diseases that, no specific treatment has yet found despite the variety of works that have done in this field. Different approaches to treat such injuries have investigated today. One of them is invasive intra-spinal interventions such as electrical stimulation. Therefore, in this study, the effect of the protocol for intra-spinal variable and fixed electrical stimulation has been investigated in order to recover from spinal cord injury. Methods: In the study, 18 Wistar male rats randomly divided into Three groups, including intraspinal electrical stimulation (IES), IES with variable pattern of stimulation (VP IES) and a sham group. Animals initially subjected to induced spinal cord injury. After one week, the animal movement was recorded on the treadmill during practice using a camera and angles of the ankle joint were measured using the Tracker software. Then, the obtained data were analyzed by nonlinear evaluations in the phase space. Results: The motion analyses and kinematic analyses were carried out on all groups. According to the achieved results, the gait dynamics of the VP IES group has the most conformity to the gait dynamics of the healthy group. Also, the best quality of the balance preservation observed in the VP IES group. Conclusion: It can be concluded that the IES with variable pattern of stimulation along with exercise therapy has significant gait restorative effects and increases the range of motion in rats with induced spinal cord injury.

Abstract Background:Motor vehicle collisions remain a common cause of spinal cord injury. Biomechanical studies of spinal movement often lack “real world” context and applicability. Additional data may enhance our understanding of the potential for secondary spinal cord injury. We propose the metric ‘travel’ (total movement) and suggest that our understanding of movement related risk of injury could be improved if travel was routinely reported. We report maximal movement and travel for collar application in vehicle and subsequent self-extrication.Methods:Biomechanical data on application of cervical collar with the volunteer sat in a vehicle were collected using Inertial Measurement Units on 6 healthy volunteers. Maximal movement and travel are reported. These data and a re-analysis of previously published work is used to demonstrate the utility of travel and maximal movement in the context of self-extrication.Results:Data from a total of 60 in-vehicle collar applications across three female and three male volunteers was successfully collected for analysis. The mean age across participants was 50.3 years (range 28–68) and the BMI was 27.7 (range 21.5–34.6). The mean maximal anterior-posterior movement associated with collar application was 2.3mm with a total AP travel of 4.9mm. Travel (total movement) for in-car application of collar and self-extrication was 9.5mm compared to 9.4mm travel for self-extrication without a collar. Conclusion:We have demonstrated the application of ‘travel’ in the context of self-extrication. Total travel is similar across self-extricating healthy volunteers with and without a collar.We suggest that where possible ‘travel’ is collected and reported in future biomechanical studies in this and related areas of research. It remains appropriate to apply a cervical collar to self-extricating casualties when the clinical target is that of movement minimisation.

Objective. To analyse the possibility of diagnostics improvement in children with spinal cord injuries. Material and Methods. The observations of 147 cases of various spinal cord injuries in children at the age of 11 months to 15 years have been analyzed. Causes of trauma, age peculiarities of spinal injury manifestations, and difficulties of clinical and radiological diagnostics are discussed. Results. Most cases of spinal cord injury in children could be revealed and adequately managed at a prehospital stage. It should be noted that the spine lesion and MRI changes do not always accompany spinal cord injury in children. This observation must be taken into account while making diagnosis. Conclusion. Electromyography is an important examination confirming spinal cord injury without radiographic abnormalities (SCIWORA syndrome) in children.

Abstract A hierarchically aligned fibrin hydrogel (AFG) that possesses soft stiffness and aligned nanofiber structure has been successfully proven to facilitate neuroregeneration in vitro and in vivo. However, its potential in promoting nerve regeneration in large animal models that is critical for clinical translation has not been sufficiently specified. Here, the effects of AFG on directing neuroregeneration in canine hemisected T12 spinal cord injuries were explored. Histologically obvious white matter regeneration consisting of a large area of consecutive, compact, and aligned nerve fibers is induced by AFG, leading to a significant motor functional restoration. The canines with AFG implantation start to stand well with their defective legs from 3 to 4 weeks postoperatively and even effortlessly climb the steps from 7 to 8 weeks. Moreover, high-resolution multi-shot diffusion tensor imaging illustrates the spatiotemporal dynamics of nerve regeneration rapidly crossing the lesion within 4 weeks in the AFG group. Our findings indicate that AFG could be a potential therapeutic vehicle for spinal cord injury by inducing rapid white matter regeneration and restoring locomotion, pointing out its promising prospect in clinic practice.
