Blood pressure regulation is impacted by a spinal cord injury (SCI) due to impaired descending sympathetic vascular control. Common blood pressure problems in the SCI population include persistently low blood pressure with bouts of orthostatic hypotension and autonomic dysreflexia, which are more prevalent in individuals with lesions above the sixth thoracic vertebral level; however, they may occur regardless of the neurological level of injury. Although blood pressure disorders adversely impact daily function and quality of life, most individuals with SCI do not acknowledge this association. Few pharmacological options have been rigorously tested for safety and efficacy to manage blood pressure disorders in the SCI population. Furthermore, clinical management of any one blood pressure disorder may adversely impact others, as such treatment is complicated and not often prioritized. 相似文献
Objective: To examine (i) the associations between physical activity dimensions, cardiorespiratory fitness and body composition and, (ii) the associations between physical activity dimensions, cardiorespiratory fitness, body composition and biomarkers of cardiometabolic health in persons with spinal cord injury (SCI).
Methods: A cross-sectional prospective cohort study with 7-day follow-up was conducted. Body composition, cardiorespiratory fitness and biomarkers of cardiometabolic health were measured in thirty-three participants with SCI (> 1 year post injury). Physical activity dimensions were objectively assessed over 7-days.
Results: Activity energy expenditure (r =.43), physical activity level (r =.39), and moderate-to-vigorous physical activity (MVPA) (r =.48) were significantly (P < 0.001) associated with absolute (L/min) peak oxygen uptake (?O2 peak). ?O2 peak was significantly higher in persons performing ≥150 MVPA minutes/week compared to <40 minutes/week (P?=?0.003). Individual physical activity dimensions were not significantly associated with biomarkers of cardiometabolic health. However, body composition characteristics (BMI, waist and hip circumference) showed significant (P < 0.04), moderate (r >.30) associations with parameters of metabolic regulation, lipid profiles and inflammatory biomarkers. Relative ?O2 peak (ml/kg/min) was moderately associated with only insulin sensitivity (r?=?0.37, P?=?0.03).
Conclusions: Physical activity dimensions are associated with cardiorespiratory fitness; however, stronger and more consistent associations suggest that poor cardiometabolic health is associated with higher body fat content. Given these findings, the regulation of energy balance should be an important consideration for researchers and clinicians looking to improve cardiometabolic health in persons with SCI. 相似文献
Due to novel gene therapy opportunities, genetic screening is no longer restricted to familial cases of ALS (FALS) cases but also aplies to the sporadic populations (SALS). Screening of four main genes (C9orf72, SOD1, TARDBP and FUS) identified the causes in 15% of Amyotrophic Lateral Sclerosis (ALS) patients (two third of the familial cases and 8% of the sporadic ones) but their respective contribution to ALS phenotype varies according the age of disease onset. The genetic overlap between ALS and other diseases is expanding and includes frontotemporal dementia, Paget's Disease of Bone, myopathy for adult cases, HSP and CMT for young cases highlighing the importance of retrieving the exhaustive familial history for each indivdual with ALS. Incomplete disease penetrance, diversity of the possible phenotypes, as well as the lack of confidence concerning the pathogenicity of most identified variants and/or possible oligogenic inheritance are burdens of ALS genetic counseling to be delivered to patients and at risk individuals. The multitude of rare ALS genetic causes identifed seems to converge to similar cellular pathways leading to inapropriate response to stress emphacising new potential therapeutic options for the disease. 相似文献
Many ambulatory patients with spinal cord injury (SCI) encountered multiple falls and serious consequences after falls, but there was no quantitative practical measure for early identification of individuals at a risk of multiple falls. This study compared the utility of the Berg Balance Scale, Timed “Up & Go” Test, 10-Meter Walk Test, Functional Reach Test (FRT), Step Test, and Five Times Sit-to-Stand Test to predict risk of multiple falls (fall ≥2 times) in these individuals.
Methods
Eighty-three independent ambulatory subjects with SCI were assessed for their functional abilities using the six tests. Then, their fall data were monitored prospectively every 2 weeks for 6 months in total. The first 25 subjects were also involved in the reliability tests.
Results
The FRT showed the best predictive ability for the risk of multiple falls (cut-off score ≥20 cm, sensitivity = 73%, specificity = 55%, area under the receiver characteristic curve = 0.64, and adjusted odd ratio = 3.18, P < 0.05), excellent inter-tester reliability, and good feasibility.
Conclusions
The FRT may be used as a screening tool to predict risk of multiple falls in independent ambulatory individuals with SCI. However, with a moderate level of specificity, a further comprehensive test may be needed to clearly indicate individuals at a risk of falls. In addition, the findings suggest that a higher level of ability increases the risk of multiple falls. Thus, programs for functional integration in an actual environment may be needed to reduce the risk of falls for these individuals. 相似文献
Great strides have been made in reducing morbidity and mortality following spinal cord injury (SCI), and improving long-term health and community participation; however, this progress has not been uniform across the globe. This review highlights differences in global epidemiology of SCI and the ongoing challenges in meeting the needs of individuals with SCI in the developing world, including post-disaster. Significant disparities persist, with life expectancies of 2 years or less not uncommon for persons living with paraplegia in many developing countries. The international community has an important role in improving access to appropriate care following SCI worldwide. 相似文献
The impulse oscillation system (IOS) offers significant value in the assessment of airway dynamics in persons with spinal cord injury (SCI) because of minimal patient effort but measurement reproducibility in SCI is unknown.
Objective
To evaluate between-day reproducibility and the effect of posture on airway resistance [respiratory resistances at 5 Hz (R5) and 20 Hz (R20)] in subjects with tetraplegia, paraplegia and able-bodied controls.
Methods
Ten subjects with tetraplegia, 10 subjects with paraplegia and 11 able-bodied individuals were evaluated using IOS. Three 30 second trials were obtained in each while in the seated and supine position on Day 1, and repeated on Day 2.
Results
The within-day coefficient of variation (CV%) for R5 and R20 were comparable in the 3 study groups in the seated and supine positions. Compared to controls, the between-day CV% for the combined data was higher in subjects with tetraplegia and paraplegia for R5 seated, and was higher in subjects with tetraplegia for R5 supine.
Conclusions
IOS has applicability to the study of within-day respiratory resistance in SCI. However, performing longer-term studies in subjects with tetraplegia and paraplegia may be problematic because of the greater variability for R5 when compared to able-bodied individuals. 相似文献
To investigate whether wearing graduated compression stockings (GCS) could affect the sympatho-adrenergic and heart rate variability (HRV) responses at rest and after a strenuous wheelchair exercise in individuals with spinal cord injury (SCI).
Design
Crossover trial.
Setting
Department of Physical Medicine and Rehabilitation, Saint Etienne, France.
Participants
Nine men with SCI (five with low paraplegia: LP, four with high paraplegia: HP).
Interventions
Two maximal wheelchair exercise tests: with and without GCS (21 mmHg).
Main outcome measures
HRV measurements: high frequency (HF), low frequency (LF), and LF/HF ratio. Norepinephrine (NOR) and epinephrine (EPI), at rest and post-exercise. Secondary measures were: blood pressure, heart rate, maximal power output, oxygen uptake, stroke volume, cardiac output, at rest, during and after exercise.
Results
When wearing GCS: LFnuwavelet-post significantly increased and HFnuwavelet-post significantly decreased (P < 0.05) in SCI subjects, leading to an enhance ratio of LFwavelet/HFwavelet and a significantly increased in NORrest (P < 0.05).
Conclusions
GCS induces an enhanced sympathetic activity in individuals with paraplegia, regardless of the level of the injury. Enhanced post-exercise sympathetic activity with GCS may help prevent orthostatic hypotension or post-exercise hypotension. 相似文献
Examine associations of type and quantity of physical therapy (PT) interventions delivered during inpatient spinal cord injury (SCI) rehabilitation and patient characteristics with outcomes at the time of discharge and at 1 year post-injury.
Methods
Physical therapists delivering routine care documented details of PT interventions provided. Regression modeling was used to predict outcomes at discharge and 1 year post-injury for a 75% subset; models were validated with the remaining 25%. Injury subgroups also were examined: motor complete low tetraplegia, motor complete paraplegia, and American Spinal Injury Association (ASIA) Impairment Scale (AIS) D motor incomplete tetra-/paraplegia.
Results
PT treatment variables explain more variation in three functionally homogeneous subgroups than in the total sample. Among patients with motor complete low tetraplegia, higher scores for the transfer component of the discharge motor Functional Independence Measure () are strongly associated with more time spent working on manual wheelchair skills. Being male is the most predictive variable for the motor FIM score at discharge for patients with motor complete paraplegia. Admission ASIA lower extremity motor score (LEMS) and change in LEMS were the factors most predictive for having the primary locomotion mode of “walk” or “both (walk and wheelchair)” on the discharge motor FIM for patients with AIS D injuries.
Conclusion
Injury classification influences type and quantity of PT interventions during inpatient SCI rehabilitation and is a strong predictor of outcomes at discharge and 1 year post-injury. The impact of PT treatment increases when patient groupings become more homogeneous and outcomes become specific to the groupings.

This study focuses on the impact a spinal cord injury may have on achieving physical and emotional intimacy, and potential to maximize sexual ability and quality of life. Spinal cord injury is a traumatic, life-altering event that is usually associated with loss of motor and sensory function, as well as sexual impairment. At the time of injury, the individual is faced with devastating loss and an abundance of new information in a setting of extreme stress and challenge. In the acute rehabilitation setting, there is often a considerable void in providing education and resources regarding sexual concerns and needs. There is a positive relationship between sexual education and sexual activity. The impact of inadequate sexual counseling and education as a part of rehabilitation can be deleterious. 相似文献
