BACKGROUND: Spinal cord injury (SCI) is characterized by a total or partial deficit of sensory and motor pathways. Impairments of this injury compromise muscle recruitment and motor planning, thus reducing functional capacity. SCI patients commonly present psychological, intestinal, urinary, osteomioarticular, tegumentary, cardiorespiratory and neural alterations that aggravate in chronic phase. One of the neurorehabilitation goals is the restoration of these abilities by favoring improvement in the quality of life and functional independence...

Context: Mineralocorticoid (MC) replacement therapy in patients with primary adrenal insufficiency (PAI) was introduced more than 60 years ago. Still, there are limited data on how MC substitution should be optimized, since MC dosing regimens have only been systematically investigated in a few studies. We review the management of current standard MC replacement therapy in PAI and its plausible impact on outcome. Evidence Acquisition: Using PubMed, we conducted a systematic review of the literature from 1939 to 2017, with the following keywords: 'adrenal insufficiency', 'mineralocorticoid deficiency', 'aldosterone', 'cardiovascular disease', 'hypertension', and 'heart failure'...

BACKGROUND: Deficit in balance control is a common and often an initial disabling symptom of multiple sclerosis (MS). We investigated the role of short-term training in improvement of anticipatory postural adjustments (APAs) and its effect on subsequent control of posture in individuals with MS. METHODS: A pre-post feasibility study involved eight individuals with relapsing-remitting MS who participated in the laboratory tests before and after a single training session consisting of throwing a medicine ball...

BACKGROUND: Individuals with limited mobility can spend prolonged periods in leisure chairs, increasing their risk of developing a seated acquired pressure ulcer. The present study aims to use objective measures of posture and tissue viability to identify the associated risks of leisure chair related pressure ulcers. METHODS: Healthy participants (n = 13) were recruited to sit on a leisure chair with either a viscoelastic foam or air cushion. Participants were asked to adopt four different postures for a period of 10 min followed by a 10 min refractory period...

Parkinson's disease (PD) is a neurodegenerative disease which causes rigidity, resting tremor and postural instability. The neuroprotective effects of an ethanolic extract of Bacopa monnieri (BM) were evaluated in a Parkinsonian mice model induced by the MPTP. The present study investigates the mechanisms of neuroprotection elicited by BM, an herb traditionally recognized by the Indian system of medicine, Ayurveda. An ethanolic extract of BM was co-treated with the MPTP induced mouse model of PD and was shown to significantly rescue the motor behaviour (Rotarod, Grip Strength and Foot Printing test)...

BACKGROUND: Kummell's disease is a clinical syndrome characterized by a minor spinal trauma with a symptom-free period from months to years, followed by progressive painful kyphosis. There are many surgical options for Kummell's disease in the previous literature, however, no study mentioning the surgical strategy for patients whose fractured vertebrae was severely compressed and only slice of superior and inferior endplate left. CASE DESCRIPTION: Here we report a 69-year-old woman suffered from persistent severe back pain since she slipped down 1 year before medical consult...

BACKGROUND AND IMPORTANCE: In contrast to cranial interventions, neuronavigation in spinal surgery is used in few applications, not tapping into its full technological potential. We have developed a method to preoperatively create virtual resection planes and volumes for spinal osteotomies and export 3-D operation plans to a navigation system controlling intraoperative visualization using a surgical microscope's head-up display. The method was developed using a Sawbone ® model of the lumbar spine, demonstrating feasibility with high precision...

During conditions of increased postural instability, older adults exhibit greater lower limb muscle co-contraction. This response has been interpreted as a compensatory postural strategy, which may be used to increase proprioceptive information from muscle spindles or to stiffen the lower limb as a general response to minimise postural sway. The current study aimed to test these two hypotheses by investigating use of muscle co-contraction during sensory transitions that manipulated proprioceptive input. Surface EMG was recorded from the bilateral tibialis anterior and gastrocnemius medialis muscles, in young (aged 18-30) and older adults (aged 68-80) during blind-folded postural assessment...

Synopsis Low back pain (LBP) is the leading cause of disability worldwide. It often begins in adolescence, setting a course for later in life. We have tracked the course of LBP in the Raine Study cohort from the age of 14 years into early adulthood. Our work has found that LBP is already prevalent in individuals at 14 years of age and increases throughout adolescence and into early adulthood. It is often comorbid with other musculoskeletal pain. For some adolescents, LBP has little impact; for others, its impact includes care seeking, taking medication, taking time off from school and work, as well as modifying physical and functional activity...

Purpose: Our goal was to test prevailing assumptions about the underlying biomechanical and aeroacoustic mechanisms associated with phonotraumatic lesions of the vocal folds using a numerical lumped-element model of voice production. Method: A numerical model with a triangular glottis, posterior glottal opening, and arytenoid posturing is proposed. Normal voice is altered by introducing various prephonatory configurations. Potential compensatory mechanisms (increased subglottal pressure, muscle activation, and supraglottal constriction) are adjusted to restore an acoustic target output through a control loop that mimics a simplified version of auditory feedback...

Robotic therapy for rehabilitation of the lower extremity is currently in its early stage of development. Aiming at exploring an efficacious intervention for gait rehabilitation, we investigate the characteristics of an end-effector gait-training device that combines saddle-seat-type body-weight-supported treadmill training with functional electrical stimulation (FES). This is a task-oriented approach to restoring voluntary control of locomotion in patients with neuromuscular diseases. We evaluate the differences between walking with saddle-seat-type support and with harness-type support, in terms of personal preference, the preferred walking speed, profiles of kinematics and ground reaction force, and the effectiveness of FES...

Exercise in the context of anorexia nervosa is a multifaceted endeavour surrounded by controversy and uncertainty. A broader comprehension of this poorly understood phenomenon is required. Informed by the findings of a body examination of six individuals with anorexia nervosa, as well as exercise science, phenomenology and neurocognition, the purpose of this article is to elaborate on the potential role of exercise and physical therapy in the treatment of anorexia nervosa. The findings of the body assessment include constriction of posture, muscles and pattern of breathing...

Background: Most animal studies of spinal cord injury are conducted in quadrupeds, usually rodents. It is unclear to what extent functional results from such studies can be translated to bipedal species such as humans because bipedal and quadrupedal locomotion involve very different patterns of spinal control of muscle coordination. Bipedalism requires upright trunk stability and coordinated postural muscle control; it has been suggested that peripheral sensory input is less important in humans than quadrupeds for recovery of locomotion following spinal injury...

BACKGROUND CONTEXT: The aim of spinal deformity correction is to restore the spine's functional alignment by balancing it in both the sagittal and coronal planes. Regardless of posture, the ideal coronal profile is straight, and therefore readily assessable. PURPOSE: This study compares two radiological methods to determine which better predicts postoperative standing coronal balance. STUDY DESIGN/SETTING: We conducted a single-centre, radiographic comparative study between 2011 and 2015...

BACKGROUND: Locomotor strategies for obstacle circumvention require appropriate postural coordination that depends on sensorimotor integration within the central nervous system. It is not known how these strategies are affected by a stroke. The objective of this study was to contrast postural coordination strategies used for obstacle circumvention between post-stroke participants (n = 12) and healthy controls (n = 12). METHODS: Participants walked towards a target in a virtual environment (11 × 8 m room) with cylindrical obstacles that were stationary or approaching from head-on, or diagonally 30° left/right...

The ongoing controversy centered on neck posture and function in sauropod dinosaurs is misplaced for a number of reasons. Because of an absence of pertinent data it is not possible to accurately restore the posture and range of motion in long necked fossil animals, only gross approximations are possible. The existence of a single "neutral posture" in animals with long, slender necks may not exist, and its relationship to feeding habits is weak. Restorations of neutral osteological neck posture based on seemingly detailed diagrams of cervical articulations are not reliable because the pictures are not sufficiently accurate due to a combination of illustration errors, and distortion of the fossil cervicals...

The aim of the present study was to examine the modification of postural symmetry during quiet standing using a sensorimotor adaptation paradigm. A group of neurologically typical adult participants performed a visually guided mediolateral (left-right) weight shifting task requiring precise adjustments in body orientation. During one phase of the task, the visual feedback of center of pressure (COP) was systematically biased toward the left or the right, requiring an adjustment in posture to compensate. COP during quiet standing without visual feedback was examined prior to and immediately following the sensorimotor adaptation procedure, in order to observe whether compensatory adjustments in postural control resulting from the visual-feedback manipulation would transfer to the control of whole-body COP during quiet standing...

OBJECTIVE: Syncope is sudden transient loss of consciousness and postural tone with spontaneous recovery; the most common form is vasovagal syncope (VVS). We previously demonstrated impaired post-synaptic adrenergic responsiveness in young VVS patients was reversed by blocking nitric oxide synthase (NOS). We hypothesised that nitric oxide may account for reduced orthostatic tolerance in young recurrent VVS patients. METHODS: We recorded haemodynamics in supine VVS and healthy volunteers (aged 15-27 years), challenged with graded lower body negative pressure (LBNP) (-15, -30, -45 mm Hg each for 5 min, then -60 mm Hg for a maximum of 50 min) with and without NOS inhibitor N(G)-monomethyl-L-arginine acetate (L-NMMA)...
