Synergistic implications of combinatorial rehabilitation approaches using spinal stimulation on therapeutic outcomes in spinal cord injury.

Objective: The objective of this narrative review was to locate and assess recent articles employing a combinatorial approach of transcutaneous spinal cord stimulation or epidural spinal cord stimulation with additional modalities. We sought to provide relevant knowledge of recent literature and advance understanding on outcomes reported, to better equip those working in neurorehabilitation and neuromodulation.

Methods: Articles were selected and analyzed based on study approach, stimulation parameters, outcome measures, and presence of neurophysiological data to support findings.

Neural coordination of bilateral hand movements: evidence for an involvement of brainstem motor centres.

Bilateral hand movements are assumed to be coordinated by a neural coupling mechanism. Neural coupling is experimentally reflected in complex electromyographic (EMG) responses in the forearm muscles of both sides to unilateral electrical arm nerve stimulation (ES). The aim of this study was to examine a potential involvement of the reticulospinal system in neural coupling by the application of loud acoustic stimuli (LAS) known to activate neurons of this system.

Central Sensitisation Syndrome: A Frequent Finding in Women with Pelvic Floor Symptoms Without Evident Urogenital Prolapse.

Introduction And Hypothesis: Women with central sensitisation syndrome (CSS) experience poorer subjective post-operative outcomes even after successful pelvic floor reconstruction. This study tests the hypothesis that women with pelvic floor symptoms (PFS) without relevant pelvic organ prolapse (POP), are more likely to have CSS.

Methods: A questionnaire was sent to women who participated in the POP-UP study in 2017.

Developmental stage of transplanted neural progenitor cells influences anatomical and functional outcomes after spinal cord injury in mice.

Neural progenitor cell (NPC) transplantation is a promising therapeutic strategy for replacing lost neurons following spinal cord injury (SCI). However, how graft cellular composition influences regeneration and synaptogenesis of host axon populations, or recovery of motor and sensory functions after SCI, is poorly understood. We transplanted developmentally-restricted spinal cord NPCs, isolated from E11.

Laparoscopic sacrocolpopexy versus vaginal sacrospinous fixation for vaginal vault prolapse: a randomised controlled trial and prospective cohort (SALTO-2 trial).

Objective: To determine whether laparoscopic sacrocolpopexy (LSC) or vaginal sacrospinous fixation (VSF) is the most optimal surgical treatment in patients with POP-Q stage ≥2 vaginal vault prolapse (VVP).

Design: Multicentre randomised controlled trial (RCT) and prospective cohort study alongside.

Setting: Seven non-university teaching hospitals and two university hospitals in the Netherlands.

Transcription Factor Hb9 Is Expressed in Glial Cell Lineages in the Developing Mouse Spinal Cord.

Hb9 () is a transcription factor described as a spinal cord motor neuron (MN)-specific marker and critical factor for the postmitotic specification of these cells. To date, expression of Hb9 in other cell types has not been reported. We performed a fate-mapping approach to examine distributions of Hb9-expressing cells and their progeny ("Hb9-lineage cells") within the embryonic and adult spinal cord of Hb9;Ai14 mice.

Fighting for recovery on multiple fronts: The past, present, and future of clinical trials for spinal cord injury.

Through many decades of preclinical research, great progress has been achieved in understanding the complex nature of spinal cord injury (SCI). Preclinical research efforts have guided and shaped clinical trials, which are growing in number by the year. Currently, 1,149 clinical trials focused on improving outcomes after SCI are registered in the U.

Effects of biological sex mismatch on neural progenitor cell transplantation for spinal cord injury in mice.

Despite advancement of neural progenitor cell transplantation to spinal cord injury clinical trials, there remains a lack of understanding of how biological sex of transplanted cells influences outcomes after transplantation. To address this, we transplanted GFP-expressing sex-matched, sex-mismatched, or mixed donor cells into sites of spinal cord injury in adult male and female mice. Biological sex of the donor cells does not influence graft neuron density, glial differentiation, formation of the reactive glial cell border, or graft axon outgrowth.

Dorsal horn neuronal sparing predicts the development of at-level mechanical allodynia following cervical spinal cord injury in mice.

Spinal cord injury (SCI) frequently results in immediate and sustained neurological dysfunction, including intractable neuropathic pain in approximately 60-80% of individuals. SCI induces immediate mechanical damage to spinal cord tissue followed by a period of secondary injury in which tissue damage is further propagated, contributing to the development of anatomically unique lesions. Variability in lesion size and location influences the degree of motor and sensory dysfunction incurred by an individual.

Restoration of motor function after CNS damage: is there a potential beyond spontaneous recovery?

What determines the effectiveness of neurorehabilitation approaches on the outcome of function in stroke or spinal cord injured subjects? Many studies claim that an improvement of function is based on the intensity of training, while some actual studies indicate no additional gain in function by a more intensive training after a stroke. Inherent factors seem to determine outcome, such as damage of specific tracts in stroke and level of lesion in spinal cord injured subjects, while the improvement of function achieved by an intensive training is small in relation to the spontaneous recovery. It is argued that an individual capacity of recovery exists depending on such factors.

Neural coordination of bilateral power and precision finger movements.

The dexterity of hands and fingers is related to the strength of control by cortico-motoneuronal connections which exclusively exist in primates. The cortical command is associated with a task-specific, rapid proprioceptive adaptation of forces applied by hands and fingers to an object. This neural control differs between "power grip" movements (e.

An Analysis of Variability in "CatWalk" Locomotor Measurements to Aid Experimental Design and Interpretation.

Preclinical studies in models of neurologic injury and disease rely on behavioral outcomes to measure intervention efficacy. For spinal cord injury, the CatWalk system provides unbiased quantitative assessment of subtle aspects of locomotor function in rodents and so can powerfully detect significant differences between experimental and control groups. Although clearly of key importance, summary group-level data can obscure the variability within and between individual subjects and therefore make it difficult to understand the magnitude of effect in individual animals and the proportion of a group that may show benefit.

Differential neural coordination of bilateral hand and finger movements.

Cooperative hand movements (e.g., opening a bottle) require a close coordination of the hands.

Coordination of bilateral synchronous and asynchronous hand movements.

This study deals with the coordination of bilateral synchronous and asynchronous hand movements. Cooperative hand movements (e.g.

Management of pain in individuals with spinal cord injury: Guideline of the German-Speaking Medical Society for Spinal Cord Injury.

Pain is a prominent complication in spinal cord injury (SCI). It can either occur as a direct or as an indirect consequence of SCI and it often heavily influences the quality of life of affected individuals. In SCI, nociceptive and neuropathic pain can equally emerge at the same time above or below the level of injury.

In vivo evidence of remote neural degeneration in the lumbar enlargement after cervical injury.

Objective: To characterize remote secondary neurodegeneration of spinal tracts and neurons below a cervical spinal cord injury (SCI) and its relation to the severity of injury, the integrity of efferent and afferent pathways, and clinical impairment.

Methods: A comprehensive high-resolution MRI protocol was acquired in 17 traumatic cervical SCI patients and 14 controls at 3T. At the cervical lesion, a sagittal T2-weighted scan provided information on the width of preserved midsagittal tissue bridges.

Neuroplastic Changes in Older Adults Performing Cooperative Hand Movements.

The aim of this study was to examine whether older adults use the same task-specific brain activation patterns during two different bimanual hand movement tasks as younger adults. Functional magnetic resonance brain imaging was performed in 18 younger (mean age: 30.3 ± 3.

Surgical management of pelvic organ prolapse.

Despite pelvic organ prolapse being a universal problem experienced in nearly 50% of parous women, the surgical management of vaginal prolapse remains an enigma to many, with wide variation in the rates and types of intervention performed. As part of the 6th International Consultation on Incontinence (ICI) our committee, charged with producing an evidence-based report on the surgical management of prolapse, produced a pathway for the surgical management of prolapse. The 2017 ICI surgical management of prolapse evidence-based pathway will be presented and summarized.

Cooperative hand movements in tetraplegic spinal cord injury patients: Preserved neural coupling.

Objectives: To evaluate whether the task-specific neural coupling mechanism during the performance of cooperative hand movements is preserved in tetraplegic subjects.

Methods: Recordings of ipsilateral and contralateral electromyographic reflex responses in activated forearm muscles and bilateral somatosensory potentials (SSEP) to unilateral ulnar nerve stimulations during rest, cooperative and non-cooperative hand movements.

Results: Contralateral reflex responses were present in almost all patients during cooperative hand movements but small in amplitude when hand function was severely impaired.

Accuracy of postvoid residual volumes after vaginal delivery: a prospective equivalence study to compare an automatic scanning device with transurethral catheterization.

Introduction And Hypothesis: Abnormal postvoid residual volumes (PVRV) after delivery are common in daily clinical practice. By using an automatic scanning device, unnecessary catheterizations can be prevented. The aim of this study was to determine the accuracy of PVRV after vaginal delivery measured by an automatic scanning device through a comparison with transurethral catheterization.

Rehabilitation robots for the treatment of sensorimotor deficits: a neurophysiological perspective.

The past decades have seen rapid and vast developments of robots for the rehabilitation of sensorimotor deficits after damage to the central nervous system (CNS). Many of these innovations were technology-driven, limiting their clinical application and impact. Yet, rehabilitation robots should be designed on the basis of neurophysiological insights underlying normal and impaired sensorimotor functions, which requires interdisciplinary collaboration and background knowledge.

Summary: 2017 International Consultation on Incontinence Evidence-Based Surgical Pathway for Pelvic Organ Prolapse.

Objective: The aim of this article is to summarize the relevant findings that inform the 2017 International Consultation on Incontinence pathway for surgical treatment of pelvic organ prolapse (POP).

Methods: We conducted an evidence-based review of the English-language peer-reviewed literature relating to POP surgery published prior to December 2016. Level 1 evidence (randomized controlled trials [RCTs] or systematic reviews of RCTs) was preferred; however, level 2 (poor-quality RCT, prospective cohort studies) or 3 evidence (case series or retrospective studies) has been included if level 1 data were lacking.
