Article Synopsis
- Recent advancements in wearable powered exoskeletons (WPE) have enabled gait training (GT) for patients with spinal cord injury, but there's a lack of focus on tetraplegic patients.
- The review aimed to evaluate the feasibility and safety of GT using WPE for tetraplegic patients and identified 41 studies, showing that while minor adverse events occurred in some cases, major events were rare and less frequent in tetraplegic patients compared to paraplegics.
- The findings suggest that GT using WPE is a safe and effective treatment for tetraplegia, highlighting the need for careful patient selection and further research to confirm potential benefits.
Ejaculation is often impaired in men with spinal cord injury (SCI). The aim of this prospective study was to assess sequence of sphincteric events and ejaculation dyssynergia during penile vibratory stimulation (PVS) in SCI men. Simultaneous recordings of bladder, bladder neck, prostate and external urethral sphincter pressures were performed using a microtip catheter with 5 pressure transducers.

Objectives: To present results of the first clinical study on a newly developed robotic exoskeleton (Atalante®, Wandercraft, Paris, France) that enables individuals with spinal cord injury (SCI) to perform ambulatory functions without technical aids.
Setting: Two sites specialized in SCI rehabilitation, France.
Sacral reflexes are important to allow the SCI practitioner to gain information about the state of the sacral spinal cord segments. The presence of the bulbocavernosus and/or the anal wink reflex indicate an intact spinal reflex arc and reflex conal autonomic function (as part of the upper motor neuron syndrome); their absence defines a lower motor neuron syndrome. The assessment of sacral reflexes helps predict the type of bladder, bowel and sexual functions and the related therapeutic interventions.

Objectives: To analyze determinants of sexual pleasure in men with spinal cord injury (SCI).
Setting: Centre Bouffard-Vercelli, Cerbere, France.
The BCR consists of the contraction of the bulbocavernosus muscle in response to squeezing the glans penis or clitoris, and is mediated through the pudendal nerve. In case of a complete lesion, the presence of BCR is indicative of intact S2-S4 spinal reflex arcs and loss of supraspinal inhibition, determining an upper motor neuron (UMN) lesion, its absence a lower motor neuron (LMN) lesion. The BCR further helps distinguish conus medullaris from cauda equina syndromes.

Spinal Cord Ser Cases
December 2017
Introduction: Spinal cord injury (SCI) creates a complex and unique syndrome of medical issues related to disruption of somatic and autonomic pathways. Among these impaired control of blood pressure (BP) can significantly impede patients' activities of daily living. The International Standards for the Assessment of Autonomic Function after SCI (ISAFSCI) is used to document the impact of SCI on resting BP (abnormal if below 90 mmHg) and the presence or absence of orthostatic hypotension (OH), defined as a symptomatic or asymptomatic decrease in BP (>/=20/10 mmHg) upon moving to an upright position.

Case Presentation: This study was conducted from May 2013 to September 2016. Antibiotic selection always followed culture collection and analysis of antibiograms.
Aim: In certain cases, a patient's anxiety, fear, or misconceptions can represent significant obstacles to the learning of Clean Intermittent Self Catheterization (CISC), and little is known about these psychological barriers. The aim of the present study is thus to construct and validate an "Intermittent Catheterization Acceptance Test (I-CAT)" to evaluate the psychological acceptance of CISC.
Methods: A study was carried out in nine neuro-rehabilitation and urology departments in French university hospitals.
Article Synopsis
- Researchers studied midodrine as a treatment for priapism caused by drug injections in spinal cord injury patients.
- Out of 354 patients treated, 14 experienced prolonged erections, with midodrine effectively returning them to normal state within 30-45 minutes.
- Midodrine was well-tolerated, had few side effects, and allowed for normal erections to be induced again within 6 months, suggesting it could be a first-line treatment option.
