Eric Weston, Peter Le, William S Marras
Twenty subjects performed typing tasks on a desktop computer and touch-screen tablet in two chairs for an hour each, and the effects of chair, device, and their interactions on each dependent measure were recorded. Biomechanical measures of muscle force, spinal load, and posture were examined, while discomfort was measured via heart rate variability (HRV) and subjective reports. HRV was sensitive enough to differentiate between chair and device interactions. Biomechanically, a lack of seat back mobility forced individuals to maintain an upright seating posture with increased extensor muscle forces and increased spinal compression...

PURPOSE: Axial fractures in patients with a previous C2-pelvis posterior instrumented fusion are rare and may be challenging to manage. Motion preservation in the axial spine for these patients is important, as the C1-2 and Occipit-C1 joints are their only remaining mobile spinal segments. In this unique report, we present for the first time the use of a fusionless occipitocervical operation for the treatment of a type II odontoid fracture and unilateral C2 pars fracture adjacent to a previous C2-pelvis posterior instrumented fusion...

Orientation of the iliac blades is a key feature that appears to distinguish extant apes from monkeys. Iliac morphology is hypothesized to reflect variation in thoracic shape that, in turn, reflects adaptations for shoulder and forearm function in anthropoids. Iliac orientation is traditionally measured relative to the acetabulum, whereas functional explanations pertain to its orientation relative to the cardinal anatomical planes. We investigated iliac orientation relative to a median plane using digital models of hipbones registered to landmark data from articulated pelves...

To study how hydrogen-rich saline (HS) promotes the recovery of testicular biological function in a hemi-sectioned spinal cord injury (hSCI) rat model, a right hemisection was performed at the T11-T12 of the spinal cord in Wistar rats. Animals were divided into four groups: normal group; vehicle group: sham-operated rats administered saline; hSCI group: subjected to hSCI and administered saline; HRST group: subjected to hSCI and administered HS. Hind limb neurological function, testis index, testicular morphology, mean seminiferous tubular diameter (MSTD) and seminiferous epithelial thickness (MSET), the expression of heme oxygenase-1 (HO-1), mitofusin-2 (MFN-2), and high-mobility group box 1 (HMGB-1), cell ultrastructure, and apoptosis of spermatogenic cells were studied...

OBJECTIVE: To identify differences in health factors, neuromuscular attributes and performance-based mobility among community-dwelling older adults with symptomatic lumbar spinal stenosis (SLSS); and to determine which neuromuscular attributes are associated with performance-based measures of mobility. We hypothesized that: (1) community-dwelling older adults with SLSS would have poorer health, greater neuromuscular impairment and worse mobility; and (2) greater impairment in trunk extensor muscle endurance, leg strength, leg speed and knee flexion range of motion (ROM) would be associated with performance-based mobility...

PURPOSE: A multi-stage image-based 3D-2D registration method is presented that maps annotations in a 3D image (e.g., point labels annotating individual vertebrae in preoperative CT) to an intraoperative radiograph in which the patient has undergone non-rigid anatomical deformation due to changes in patient positioning or due to the intervention itself. METHODS: The proposed method (termed msLevelCheck) extends a previous rigid registration solution (LevelCheck) to provide an accurate mapping of vertebral labels in the presence of spinal deformation...

Background.: The Berg Balance Scale (BBS) has several constraints-ceiling effect, low responsiveness, and uncertain predictability of falls-in neurological populations. The Mini-BESTest, which has not yet been validated in spinal cord injury (SCI) populations, has shown no ceiling effect, slightly better responsiveness, and could in some neurological populations predict falls. Objective.: Validate and compare psychometric performances of the BBS and Mini-BESTest in individuals with chronic SCI...

BACKGROUND: People with chronic tetraplegia, due to high-cervical spinal cord injury, can regain limb movements through coordinated electrical stimulation of peripheral muscles and nerves, known as functional electrical stimulation (FES). Users typically command FES systems through other preserved, but unrelated and limited in number, volitional movements (eg, facial muscle activity, head movements, shoulder shrugs). We report the findings of an individual with traumatic high-cervical spinal cord injury who coordinated reaching and grasping movements using his own paralysed arm and hand, reanimated through implanted FES, and commanded using his own cortical signals through an intracortical brain-computer interface (iBCI)...

BACKGROUND: MyD88 is the adaptor protein of MyD88-dependent signaling pathway of TLRs and IL-1 receptor and regulates innate immune response. However, it was not clear whether and how MyD88 and related signaling pathways in the dorsal root ganglion (DRG) and spinal dorsal horn (SDH) are involved in neuropathic pain. METHODS: Chronic constriction injury (CCI) was used to induce neuropathic pain in the rat. The expression of MyD88, TRIF, IBA1, and GFAP was detected with immunofluorescent staining and Western blot...

BACKGROUND A case of spinal trauma had an unusual clinical course due to medical mistakes, from which we can learn some important lessons. CASE REPORT We report a case of spondylolisthesis following a bomb explosion, which went undiagnosed for a long time because of a series of mistakes that are highlighted in this article. What makes this case unique is that the spondylolisthesis developed during hospital stay, but the patient had no loss of mobility, strength, or sensitivity. CONCLUSIONS This case shows that establishing the conditions of an organ or a body part upon admission to hospital may not be enough when a patient has suffered extensive and serious trauma, and that it is necessary to carry out more checkups over time, especially if there are new clues and symptoms...
