Continuous, bilateral Achilles' tendon vibration is not detrimental to human walk.

2001

Sensory feedback from the moving limbs contributes to the regulation of animal and human locomotion. However, the question of the specific role of the various modalities is still open. Further, functional loss of leg afferent fibres due to peripheral neuropathy does not always lead to major alteration in the gait pattern. In order to gain further insight on proprioceptive control of human gait, we applied vibratory tendon stimulation, known to recruit spindle primary afferent fibres, to both triceps surae muscles during normal floor walk. This procedure would disturb organisation and execution of walking, especially if spindles fire continuously and subjects are blindfolded. Vibration induc…

Emergency radiology: straightening of the cervical spine in MDCT after trauma--a sign of injury or normal variant?

2016

To evaluate whether straightening of the cervical spine (C-spine) alignment after trauma can be considered a significant multidetector CT (MDCT) finding.160 consecutive patients after C-spine trauma admitted to a Level 1 trauma centre received MDCT according to Canadian Cervical Spine Rule and National Emergency X-Radiography Utilization Study indication rule; subgroups with and without cervical collar immobilization (CCI +/-) were compared with a control group (n = 20) of non-traumatized patients. Two independent readers evaluated retrospectively the alignment, determined the absolute rotational angle of the posterior surface of C2 and C7 (ARA C2-7) and grouped the results for lordosis (-1…

Indication Variability in Degenerative Lumbar Spine Surgery: A Four-nation Survey.

2017

Electronic survey.The aim of this study was to identify the international nuances in surgical treatment patterns for severals lumbar degenerative conditions, specifically, to identify differences in responses in each country groupand different treatment trends across countries.Significant variations in treatment of lumbar degenerative conditions exist among spine surgeons, related to the lack of established consensus in the literature.An online survey with preformulated answers was submitted to 52 orthopedic surgeons, 50 neurosurgeons from four different countries (United States, France, Spain, and Germany) regarding five vignette-cases. Cases included: multilevel stenosis, monolevel stenos…

Advanced magnetic resonance imaging of cortical laminar necrosis in patients with stroke

2019

Purpose The aim of this study was to assess the novel advanced magnetic resonance imaging findings of acute stage cortical laminar necrosis developing after complicated cardiovascular or abdominal surgery. Materials and methods This institutional review board-approved study included patients with postoperative stroke due to cortical laminar necrosis imaged with magnetic resonance in the acute stage. Brain magnetic resonance imaging examinations were obtained on a 3T magnetic resonance scanner within 48 hours of the neurological symptoms, including diffusion-weighted images (b value, 1000 s/mm2) and arterial spin labelling using a pseudo-continuous arterial spin labelling method in four pati…

Clinically atypical spitzoid lesions: semi-quantitative histologic index correlation with dermoscopic scores (ABCD rule, 7-point checklist and patter…

2014

Background The distinction of Spitz and Reed nevi with atypical features from melanoma may be a difficult task. In these cases, the dermoscopic scores could bring variable results and not always correlate with the histologic diagnosis. Objective The aim of this study was to compare the histopathologic and dermoscopic findings in a cohort of clinically atypical Spitz and Reed nevi. Methods We retrospectively reviewed 19 cases of atypical Spitz and Reed nevi from our files. We constructed a new semi-quantitative histologic index (HI) based on the reproducible microscopic features, and correlated it with two dermoscopic scores: ABCD and 7-point checklist, as well as with the predominant dermos…

Cervical Spondylotic Myelopathy: When and Why the Cervical Corpectomy?

2020

Background: Cervical spondylotic myelopathy (CSM) is a degenerative disease that represents the most common spinal cord disorder in adults. The best treatment option has remained controversial. We performed a prospective study to evaluate the clinical, radiographic, and neurophysiologic outcomes for anterior cervical corpectomy in the treatment of CSM. Methods: From January 2011 to January 2017, 60 patients with CSM were prospectively enrolled in the present study. The patients were divided according to the modified Japanese Orthopaedic Association scale (mJOA) score into 2 groups: group A, patients with mild to moderate CSM (mJOA score ≥13); and group B, patients with severe myelopathy (mJ…

A Randomized-Controlled Study of Intrathecal Versus Epidural Thoracic Analgesia in Patients Undergoing Abdominal Cancer Surgery

2008

Background. We sought to determine the effectiveness of continuous intrathecal thoracic analgesia (ITA) in comparison with continuous epidural thoracic analgesia (ETA) for the management of postoperative pain after abdominal cancer surgery in a randomised controlled study. Materials and methods. Catheters were inserted at T8-10 level for both techniques. Sixty patients were randomized to receive ITA providing levobupivacaine 0.25%, at 0.5-0-7 ml/h, associated with a single bolus of morphine 0.15 mg, or ETA with levobupivacaine 0.25% 4-6 ml/h and a single bolus of epidural morphine 2-3 mg. Data were collected before discharging from recovery room to the surgical ward, 1, 2, 3, 8, 12, 24 h, a…

Selective activation of shoulder, trunk, and arm muscles: A comparative analysis of different push-up variants

2015

Context The push-up is a widely used exercise for upper limb strengthening that can be performed with many variants. A comprehensive analysis of muscle activation during the ascendant phase (AP) and descendant phase (DP) in different variants could be useful for trainers and rehabilitators. Objective To obtain information on the effect of different push-up variants on the electromyography (EMG) of a large sample of upper limb muscles and to investigate the role of the trunk and abdomen muscles during the AP and DP. Design Cross-sectional study. Setting University laboratory. Patients or Other Participants Eight healthy, young volunteers without a history of upper extremity or spine injury.…

Heart rate variability in individuals with thoracic spinal cord injury

2014

Cross-sectional study. The main goal of our study was to explore the differences in heart rate variability (HRV) while sitting between able-bodied (AB) participants and paraplegic (P) individuals. The study was conducted in the Physical Therapy department and the Physical Education and Sports department of the University of Valencia and Vall d’Hebron Hospital. To record the HRV, a 1000-Hz Suunto Oy t6 heart rate monitor was used. The data were analyzed in the temporal and frequency domains, and nonlinear analysis was performed as well. We found significant differences between P and AB participants in SDNN: t(76)=2.81, P<0.01; root mean squared of the difference of successive RR intervals: t…
