Background: Spinal cord injury results in permanent neurological impairment and disability due to the absence of spontaneous regeneration. NG101, a recombinant human antibody, neutralises the neurite growth-inhibiting protein Nogo-A, promoting neural repair and motor recovery in animal models of spinal cord injury. We aimed to evaluate the efficacy of intrathecal NG101 on recovery in patients with acute cervical traumatic spinal cord injury.

Study Design: A psychometric study.

Objectives: To introduce a novel simple tool designed to evaluate the intensity of the phasic (dynamic) component of spastic motor behavior in spinal cord injury (SCI) people and to assess its reliability and validity.

Setting: The study was developed in the Spinal Cord Unit at University Hospital Motol and Paraple Centre in Prague, Czech Republic.

Introduction: The increase of multidrug-resistant (MDR) bacteria in healthcare settings is a worldwide concern. Isolation precautions must be implemented to control the significant risk of transmitting these pathogens among patients. Antibiotic decolonization is not recommended because of the threat of increasing antibiotic resistance.

Background: The recovery of autonomic functions and the ability to reproduce in particular is of the highest priority to individuals with spinal cord injury (SCI). The potential of epidural spinal cord stimulation (ESCS) for promoting recovery of sensorimotor functions in the chronic phase of SCI has long been studied. In recent years, several studies have emerged confirming the positive effect of ESCS also on the cardiovascular system and neurogenic bladder and bowel.

Background: Accurate prediction of walking function after a traumatic spinal cord injury (SCI) is crucial for an appropriate tailoring and application of therapeutical interventions. Long-term outcome of ambulation is strongly related to residual muscle function acutely after injury and its recovery potential. The identification of the underlying determinants of ambulation, however, remains a challenging task in SCI, a neurological disorder presented with heterogeneous clinical manifestations and recovery trajectories.

Objectives: Since their introduction, electronic International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) calculators have evolved to powerful tools providing error-free ISNCSCI classifications in education, research and clinical practice. For increased accessibility and dissemination, a multilingual support is mandatory. The aim of this work was to setup a general multilingual framework for the freely available ISNCSCI calculator ( https://ais.

Study Design: A retrospective cohort study OBJECTIVES: To determine the causes of death in people with spinal cord injury (SCI) admitted to the Spinal Cord Unit (SCU) of the University Hospital Motol from 2004 to 2018.

Setting: University Hospital Motol, Prague METHODS: From a cohort of people admitted to the SCU between 2004 and 2018, all deaths were identified based on the database of health insurance companies. The causes of death (ICD-10) were obtained from the Institute of Health Information and Statistics.

Article Synopsis
  • * Patients aged 18 and older were evaluated at 1, 3, and 6 months after the injury, measuring neurological and functional recovery through standardized assessments.
  • * Results showed both groups improved significantly without differences in recovery trajectories, suggesting iSCI patients can be considered for clinical trials starting from about 15 days post-injury.

Study Design: Retrospective analysis of prospectively collected data.

Objective: Central cord syndrome (CCS) is reported to have better outcomes than other cervical lesions, especially for ambulation and bladder recovery. However, a formal comparison between patients with CCS and other incomplete cervical spinal cord injuries (iCSCI) is lacking.

Study Design: Multicenter prospective cohort.

Objective: To discern neurological- and functional recovery in patients with a traumatic thoracic spinal cord injury (TSCI), conus medullaris syndrome (CMS), and cauda equina syndrome (CES).

Setting: Specialized spinal cord injury centers in Europe.

Hemicorporectomy is the amputation of the lower body - pelvis and lower limbs. It requires transection of the spine and dural sac at the level of aortic bifurcation and inferior lower vein, and permanent urinary and stool derivation. Performance indications are tumour trauma and terminal pelvic osteomyelitis.

Introduction: After spinal cord injury (SCI), individuals are typically considered by the general public to be asexual. Handicapped women have more problems with socio-sexual adaptation, stemming from low self-confidence, low self-esteem, and the absence of spontaneity.

Aims: To determine changes in the sexual lives of women after SCI.

Background: Abdominal muscles are important spinal stabilizers and its poor coordination, as seen in diastasis of rectus abdominis (DRA), may contribute to chronic low back pain (LBP). However, this has not yet been studied directly.

Objectives: To conduct a pilot study to examine the association between DRA and LBP.

Objectives: Respiratory complications are most common cause of morbidity/mortality in patients with cervical spinal cord injury (cSCI) due to respiratory muscle weakness and lower diaphragm position resulting in limited availability of inspiration, reduced thorax mobility and limited forced expiration. Differences in respiratory dysfunctions (RDs) in patients with motor complete versus incomplete cSCI were assessed.

Design: Prospective longitudinal study, serial measurement.

Context/objective: Traumatic damage to the cervical spinal cord is usually associated with a disruption of the autonomic nervous system (ANS) and impaired cardiovascular control both during and following exercise. The magnitude of the cardiovascular dysfunction remains unclear. The aim of the current study was to compare cardiovascular responses to peak voluntary exercise in individuals with tetraplegia and able-bodied participants.

Study Design: Case report.

Context: In patients with a complete spinal cord injury (SCI) above T6 level, autonomic dysreflexia (AD) can be the only alerting sign of complications below the level of injury. A case report is presented of a patient with tetraplegia who progressively developed an AD syndrome after falling from a wheelchair.

Objectives And Methods: Excitability changes in the primary motor cortex in 17 spinal-cord injured (SCI) patients and 10 controls were studied with paired-pulse transcranial magnetic stimulation. The paired pulses were applied at inter-stimulus intervals (ISI) of 2 ms and 15 ms while motor evoked potentials (MEP) were recorded in the biceps brachii (Bic), the abductor pollicis brevis (APB) and the tibialis anterior (TA) muscles.

Results: The study revealed a significant decrease in cortical motor excitability in the first weeks after SCI concerning the representation of both the affected muscles innervated from spinal segments below the lesion, and the spared muscles rostral to the lesion.
