Comparison of the effects of body-weight-supported treadmill training and tilt-table standing on spasticity in individuals with chronic spinal cord injury

Objective

Determine the effects of body-weight-supported treadmill training (BWSTT) and tilt-table standing (TTS) on clinically assessed and self-reported spasticity, motor neuron excitability, and related constructs in individuals with chronic spinal cord injury (SCI).

Design

Random cross-over.

Methods

Seven individuals with chronic SCI and spasticity performed thrice-weekly BWSTT for 4 weeks and thrice-weekly TTS for 4 weeks, separated by a 4-week wash-out. Clinical (Modified Ashworth Scale, Spinal Cord Assessment Tool for Spinal reflexes) and self-report (Spinal Cord Injury Spasticity Evaluation Tool, Penn Spasm Frequency Scale) assessments of spasticity, quality of life (Quality of Life Index Spinal Cord Injury Version – III), functional mobility (FIM Motor Subscale), plus soleus H-reflex were measured at baseline, after the first training session and within 2 days of completing each training condition.

Results

In comparison with TTS, a single session of BWSTT had greater beneficial effects for muscle tone (effect size (ES) = 0.69), flexor spasms (ES = 0.57), and the H/M ratio (ES = 0.50). Similarly, flexor spasms (ES = 0.79), clonus (ES = 0.66), and self-reported mobility (ES = 1.27) tended to benefit more from 4 weeks of BWSTT than of TTS. Participation in BWSTT also appeared to be favorable for quality of life (ES = 0.50). In contrast, extensor spasms were reduced to a greater degree with TTS (ES = 0.68 for single session; ES = 1.32 after 4 weeks).

Conclusion

While both BWSTT and TTS may provide specific benefits with respect to spasticity characteristics, data from this pilot study suggest that BWSTT may result in a broader range of positive outcomes.     

Etanercept treatment enhances clinical and neuroelectrophysiological recovery in partial spinal cord injury

Purpose

To investigate the effect of an anti-TNF-α agent (etanercept) on recovery processes in a partial spinal cord injury (SCI) model using clinical and electrophysiological tests.

Methods

Twenty-four New Zealand rabbits were divided into three groups: group 1 [SCI + 2 ml saline intramuscular (i.m.), n = 8], group 2 (SCI + 2.5 mg/kg etanercept, i.m., 2–4 h after SCI, n = 8) and group 3 (SCI + 2.5 mg/kg etanercept, i.m., 12–24 h after SCI, n = 8). Rabbits were evaluated before SCI, immediately after SCI, 1 week after, and 2 weeks after SCI, clinically by Tarlov scale and electrophysiologically by SEP.

Results

Tarlov scores of groups 2 and 3 were significantly better than group 1, 2 weeks after SCI. SEP recovery was significantly better in groups 2 and 3 than group 1, 2 weeks after SCI.

Conclusions

These results show that blocking TNF-α mediated inflammation pathway by an anti-TNF-α agent enhances clinical and electrophysiological recovery processes in partial SCI model.     

Examining implicit bias of physicians who care for individuals with spinal cord injury: A pilot study and future directions

Context

Despite evidence that healthcare providers have implicit biases that can impact clinical interactions and decisions, implicit bias among physicians caring for individuals with spinal cord injury (SCI) has not been examined.

Objective

Conduct a pilot study to examine implicit racial bias of SCI physicians and its association with functioning and wellbeing for individuals with SCI.

Design

Combined data from cross-sectional surveys of individuals with SCI and their SCI physicians.

Setting

Four national SCI Model Systems sites.

Participants

Individuals with SCI (N = 162) and their SCI physicians (N = 14).

Outcome measures

SCI physicians completed online surveys measuring implicit racial (pro-white/anti-black) bias. Individuals with SCI completed questionnaires assessing mobility, physical independence, occupational functioning, social integration, self-reported health, depression, and life satisfaction. We used multilevel regression analyses to examine the associations of physician bias and outcomes of individuals with SCI.

Results

Physicians had a mean bias score of 0.62 (SD = 0.35), indicating a strong pro-white/anti-black bias. Greater physician bias was associated with disability among individuals with SCI in the domain of social integration (odds ratio = 4.80, 95% confidence interval (CI) = 1.44, 16.04), as well as higher depression (B = 3.24, 95% CI = 1.06, 5.41) and lower life satisfaction (B = −4.54, 95% CI= −8.79, −0.28).

Conclusion

This pilot study indicates that SCI providers are susceptible to implicit racial bias and provides preliminary evidence that greater implicit racial bias of physicians is associated with poorer psychosocial health outcomes for individuals with SCI. It demonstrates the feasibility of studying implicit bias among SCI providers and provides guidance for future research on physician bias and patient outcomes.     

Soleus H-reflex modulation after motor incomplete spinal cord injury: effects of body position and walking speed

Objective:

To examine position-dependent (semireclined to standing) and walking speed–dependent soleus H-reflex modulation after motor incomplete spinal cord injury (SCI).

Participants:

Twenty-six patients with motor incomplete SCI (mean: 45 ± 15 years) and 16 noninjured people (mean: 38 ± 14 years).

Methods:

Soleus H-reflexes were evoked by tibial nerve stimulation. Patients were tested in semireclined and standing positions (experiment 1) and in midstance and midswing positions (experiment 2).

Results:

H-reflexes were significantly greater after SCI in all positions compared with noninjured people (P < 0.05). Position-dependent modulation from semireclined to standing (normally observed in noninjured people) was absent after SCI. In SCI patients, H-reflex modulation was not significantly different at 1.2 m/s compared with 0.6 m/s treadmill walking speed; in noninjured people, H-reflex modulation was significantly greater at 1.2 m/s compared with 0.6 m/s treadmill walking speed. There was a significant positive correlation between modified Ashworth scores, a clinical measure of spasticity and soleus H-reflex amplitudes tested in all positions. A significant negative correlation was also found between H-reflexes in standing and midstance positions and the amount of assistance patients required to walk.

Conclusions:

An improvement in position-dependent and walking speed–dependent reflex modulation after SCI may indicate functional recovery. Future studies will use H-reflex testing to track changes as a result of therapeutic interventions.     

Efficacy of cranial electrotherapy stimulation for neuropathic pain following spinal cord injury: a multi-site randomized controlled trial with a secondary 6-month open-label phase

Background

Chronic pain is a significant problem for many individuals following spinal cord injury (SCI). Unfortunately, SCI-related neuropathic pain has proven to be largely refractory to analgesic medications and other available treatments. Cranial electrotherapy stimulation (CES) has been effective in managing some types of pain. It involves the application of a small amount of current through the head via ear clip electrodes.

Objective

Explore the effectiveness of CES for neuropathic pain in persons with SCI and chronic pain.

Study design

Multi-site, double-blind, sham-controlled study.

Participants

Adults with SCI and chronic neuropathic pain at or below the level of injury were randomized to receive active or sham CES.

Intervention

Application of active CES or sham CES 1 hour daily for 21 days. Six-month open-label phase to assess ‘as-needed’ CES use.

Outcome measures

Change in pre- to post-session pain ratings as well as change in pain intensity, pain interference, pain quality, pain beliefs and coping strategies, general physical and mental health status, depressive symptomatology, perceived stress, and anxiety pre- to post-treatment.

Results

The active group reported a significantly greater average decrease in pain during daily treatments than the sham group (Kruskal–Wallis chi-square = 4.70, P < 0.05). During the 21-day trial, there was a significant group × time interaction for only one outcome variable; the active group showed larger pre- to post-treatment decreases in pain interference than the sham group did (F = 8.50, P < 0.01, d = 0.59).

Conclusions

On average, CES appears to have provided a small but statistically significant improvement in pain intensity and pain interference with few troublesome side effects. Individual results varied from no pain relief to a great deal of relief.     

Effects of compression stockings on sympathetic activity and heart rate variability in individuals with spinal cord injury

Objective

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: LFnu_wavelet-post significantly increased and HFnu_wavelet-post significantly decreased (P < 0.05) in SCI subjects, leading to an enhance ratio of LF_wavelet/HF_wavelet and a significantly increased in NOR_rest (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.     

Assessing the feasibility of subepidermal moisture to predict erythema and stage 1 pressure ulcers in persons with spinal cord injury: a pilot study

Background

Persons with spinal cord injury (SCI) are at high risk for pressure ulcers (PrUs) throughout their lifetime due to decreased mobility, lack of sensation, and other physiological changes. The high prevalence and recurrence rates, and costs associated with PrUs in veterans with SCI indicate the need for a reliable and practical method of detecting early PrUs.

Objective

To assess the feasibility of obtaining biophysical measures of sub-epidermal moisture (SEM) using a handheld dermal phase meter to predict PrUs.

Design/methods

Prospective observational design. Thirty-four veterans at two VA SCI centers (Hines, Long Beach) received daily (n = 12) or weekly (n = 22) SEM and concurrent visual skin assessment (VSA) across nine anatomic locations for up to 6 weeks.

Outcome measures

SEM, visual skin assessment (VSA), and stage I PrUs.

Findings/results

SEM was lowest for normal skin (39.3 dermal phase units (DPU), SD = 12.6) and higher for erythema/stage 1 PrUs (40.8 DPU, SD = 10.4) across all anatomic sites. Buttocks SEM were different between normal skin (40.5 DPU, SD = 10.3) and erythema/stage1 PrUs (43.8, SD = 9.5). SEM taken at heels were lower across all skin conditions (normal skin 28.2 DPU; erythema/stage 1 PrUs 34.7 DPU). SEM was taken when generalized edema present was lower than without generalized edema.

Conclusions

Preliminary results of using SEM to detect early PrU damage may translate from nursing home (NH) residents to persons with SCI. This study provides a foundation for a larger study to implement and assess SEM use as a method of prevention of PrUs.     

Dysphagia in individuals with tetraplegia: incidence and risk factors

Background/objective

Dysphagia following cervical spinal cord injury (SCI) can increase risk for pulmonary complications that may delay the rehabilitative process. The objective of this study was to identify risk factors for dysphagia after cervical SCI.

Design

Prospective cohort study.

Methods

Individuals with cervical SCI within 31 days of injury underwent a bedside swallow evaluation (BSE) followed by a videofluoroscopy swallow study (VFSS) within 72 hours of the BSE. Subjects were diagnosed as having dysphagia if they had positive findings in either BSE or VFSS.

Results

Twenty-nine patients (7 female and 22 male) were enrolled. Of these, 21 (72%) had high cervical tetraplegia (C4 or higher) and 8 (38%) had lower cervical tetraplegia. A tracheostomy was present in 18 (62%) patients; 15 (52%) subjects were on ventilators. Dysphagia was diagnosed in 12 (41%) subjects. Dysphagia was noted in 62% of the subjects with tracheostomy and 53% of the subjects on the ventilator, but only tracheostomy resulted in a statistically significant association with dysphagia (P = 0.047). All three subjects who had nasogastric tubes were diagnosed with dysphagia (P = 0.029). The relationships between dysphagia and gender, high versus low tetraplegia, presence of halo or collar, head injury, and ventilator use were not statistically significant, but age was a significant risk factor (P = 0.028).

Conclusions

Dysphagia is present in about 41% of individuals with acute tetraplegia. Only age, tracheostomy, and nasogastric tubes were identified as significant risk factors for dysphagia for individuals with tetraplegia. No relationship between dysphagia and level of SCI, spine surgery, collar, and ventilator use was found to exist.     

The effect of repetitive transcranial magnetic stimulation on refractory neuropathic pain in spinal cord injury

Objective

To investigate the analgesic effect of repetitive transcranial magnetic stimulation (rTMS) on intractable neuropathic pain in patients with spinal cord injury (SCI).

Design

A single center, prospective, randomized, double-blinded, controlled study.

Setting

SCI rehabilitation unit of university rehabilitation center.

Participants

Seventeen patients with SCI and chronic neuropathic pain who met the inclusion criteria recruited between April 2010 and January 2012.

Interventions

Ten daily treatment sessions of real or sham rTMS (30 trains of 10-Hz stimuli for a duration of 5 seconds; a total of 1500 pulses at intensity equal to 110% of the resting motor threshold) was applied over vertex using a figure-of-8-shaped coil.

Outcome measures

Pain was assessed with visual analog scale (VAS) at baseline and 10 days, 6 weeks and 6 months after the treatment. Patients’ satisfactions obtained using a 5-point Likert scale at 6 months.

Results

Both real and sham rTMS provided a significant reduction in the VAS scores (real rTMS group, P = 0.004; sham rTMS group, P = 0.020). Post hoc analysis revealed the significant difference was at 10 days and 6 weeks compared to baseline in the real rTMS group and only at 10 days compared to baseline in the sham rTMS group. Comparison of VAS scores and patient satisfaction did not show any significant difference at each assessment point (P > 0.05).

Conclusion

Our results demonstrated analgesic effect of rTMS on intractable neuropathic pain in SCI was not superior to placebo. However, middle-term (over 6 weeks) pain relief by rTMS is encouraging and suggests the need for future studies with a larger sample size.     

Assessment of passive knee stiffness and viscosity in individuals with spinal cord injury using pendulum test

Objective

Stiffness and viscosity represent passive resistances to joint motion related with the structural properties of the joint tissue and of the musculotendinous complex. Both parameters can be affected in patients with spinal cord injury (SCI). The purpose of this study was to measure passive knee stiffness and viscosity in patients with SCI with paraplegia and healthy subjects using Wartenberg pendulum test.

Design

Non-experimental, cross-sectional, case–control design.

Setting

An outpatient physical therapy clinic, University of social welfare and Rehabilitation Science, Iran.

Patients

A sample of convenience sample of 30 subjects participated in the study. Subjects were categorized into two groups: individuals with paraplegic SCI (n = 15, age: 34.60 ± 9.18 years) and 15 able-bodied individuals as control group (n = 15, age: 30.66 ± 11.13 years).

Interventions

Not applicable.

Main measures

Passive pendulum test of Wartenberg was used to measure passive viscous-elastic parameters of the knee (stiffness, viscosity) in all subjects.

Results

Statistical analysis (independent t-test) revealed significant difference in the joint stiffness between healthy subjects and those with paraplegic SCI (P = 0.01). However, no significant difference was found in the viscosity between two groups (P = 0.17). Except for first peak flexion angle, all other displacement kinematic parameters exhibited no statistically significant difference between normal subjects and subjects with SCI.

Conclusions

Patients with SCI have significantly greater joint stiffness compared to able-bodied subjects.     

Comparison of coronary artery calcification scores and National Cholesterol Education program guidelines for coronary heart disease risk assessment and treatment paradigms in individuals with chronic traumatic spinal cord injury

Objective

To investigate the risk of coronary heart disease (CHD) in individuals with spinal cord injury (SCI) according to the National Cholesterol Educational Program (NCEP) guidelines and CT coronary artery calcium scores (CCS).

Research

Cross-sectional study of consecutive sample of males with SCI presenting to a single site for CHD risk assessment.

Participants/methods

Males age 45–70 with traumatic SCI (American Spinal Injury Association (ASIA) A, B, and C) injured for at least 10 years with no prior history of clinical CHD. Medical history, blood-pressure, and fasting lipid panel were used to calculate risk for CHD with the use of the Framingham risk score (FRS). Risk and treatment eligibility status was assessed based on NCEP/FRS recommendations and by presence and amount of CCS. Percent agreement (PA) and kappa were calculated between the two algorithms. Spearman correlations were calculated between CCS and FRS and individual risk factors.

Results

A total of 38 men were assessed; 18 (47.4%) had CCS > 0. The PA between NCEP/FRS assessment and CCS was 18% with a kappa of −0.03. 11 (28.9%) had CCS > 100 or >75th percentile for their age, sex, and race, which might qualify them for lipid-lowering treatment. Only 26 were placed into the same treatment category by NCEP/FRS and CCS, for a PA of 68% with a kappa of 0.35. In all, 20 (52.6%) were eligible for lipid-lowering treatment by either NCEP/FRS (n = 9) or CCS (n = 11). Seven subjects were above the treatment threshold based on CCS, but not NCEP/FRS and five subjects were above the NCEP/FRS threshold, but not CCS. Just four subjects were eligible by both algorithms. CCS only correlated with FRS (r = 0.508, P = 0.001) and age (r = 0.679, P < 0.001).     

Body composition modifications in people with chronic spinal cord injury after supervised physical activity

Background

Quantification of body composition variables is important for planning of better activities in relation to individuals with spinal cord injury (SCI).

Objectives

(1) To evaluate changes in body composition in patients with SCI after a supervised physical activity process; (2) To correlate total body fat with time since injury.

Design

Pre-post intervention.

Setting

Sarah Rehabilitation Hospital Network, Brazil.

Participants

Fifty-three men with SCI aged 18–52 years with duration of injury >3 years.

Interventions

The subjects were divided into three groups: tetraplegia (TT) (C5–C8), high paraplegia (HP) (T1–T6), and low paraplegia (LP) (T7–L2). Body composition was estimated in the first and last weeks of hospitalization.

Outcome measures

Body weight (kg), skinfolds sum (mm), absolute (kg), and relative (%) fat and lean body mass.

Results

Body weight increased in TT and decreased in HP (0.8 kg, 95%CI 0.1–1.5; and −1.0 kg, 95%CI −2.0 to 0.0, respectively; P < 0.05). Skinfolds sum decreased only in HP (−13.1 mm, 95%CI −20.7 to −5.5; P < 0.05). Absolute and relative body fat decreased significantly in the paraplegia groups. Lean body mass (LBM) percentage increased significantly in the paraplegia groups. Absolute LBM increased in TT and LP (0.8 kg, 95%CI 0.3–1.3; and 1.3 kg, 95%CI 0.8 to 1.8, respectively; P < 0.05). There was no correlation between time since injury and skinfolds sum for the three groups (P < 0.05).

Conclusion

TT, HP, and LP demonstrated favorable changes in body composition after 29 days of supervised physical activity. However, these changes were different in direction and magnitude.     

Association between seeking oral health information online and knowledge in adults with spinal cord injury: a pilot study

Objective

To characterize adults with spinal cord injury (SCI) who seek oral health information online, and investigate whether seeking oral health information online is associated with oral health knowledge and behaviors.

Methods

An online oral health survey was posted on the South Carolina Spinal Cord Injury Association website. Respondents were 192 adult residents of the US ages 19–83 years who identified themselves as having SCI occurring at least 1 year before the survey date.

Results

About 12% (n = 23) of the respondents searched oral health information online in the past 12 months. Significant associations between the proportion of respondents who searched for oral health information online and socio-demographic and the proportion of respondents who engaged in various oral health behaviors were not detected. However, multivariable logistic regression indicated that respondents who searched oral health information online in the past 12 months have 3.4 times the odds of possessing adequate oral health knowledge compared to respondents who did not search oral health information online (adjusted odds ratio = 3.41, 95% confidence interval = 1.35, 8.62, P = 0.01).

Conclusions

Given the significant association between seeking oral health information online and adequate oral health knowledge, this study suggests that online oral health information may be a potential avenue for dental health professionals to supplement oral health education in adults with SCI.     

Do vascular risk factors contribute to the prevalence of pressure ulcer in veterans with spinal cord injury?

Objective

The overall goal of this observational study was to determine whether modifiable vascular risk factors contribute to the prevalence of pressure ulcers (PrU) in veterans with traumatic spinal cord injury (SCI).

Background

Given the increasingly limited financial resources in hospitals and clinics, identifying risk factors associated with the development of PrU in persons with SCI will be a major step in reducing the cost of care for these individuals, and may improve their quality of life.

Method

We retrospectively reviewed the electronic charts of 87 veterans with SCI who are being followed regularly in our SCI clinic and are enrolled in the SCI registry. The data collected included the basic demographics, presence of modifiable vascular risk factors such as hypertension, diabetes mellitus, hyperlipidemia, and current smoking; presence of incontinence and depression; and results from blood drawn for hemoglobin level, blood urea nitrogen, creatinine, and albumin levels and lipid profile on veteran''s initial enrollment. Local Institution Review Board approval was obtained for the protocol.

Results

Of the 87 veterans with SCI, 27 had PrU. Comparisons between those with and without PrU found no significant differences for the demographic variables of age, gender, age of SCI onset, or SCI duration, but there was a trend for the groups to differ in ethnicity (P = 0.05). Similarly, the presence of modifiable vascular risk factors including hypertension, diabetes mellitus, hyperlipidemia, and current smoking did not differ between those with and without PrU. There were 36 pressure ulcer sites observed in 27 people. The proportion of pressure ulcer sites (of the 36) significantly differed by SCI severity based on the American Spinal Injury Association (ASIA) score (P < 0.0001).

Conclusion

This study suggests that the presence of PrU was influenced by the severity of the SCI without any contribution from modifiable vascular risk factors.     

Efficacy of multilevel anterior cervical discectomy and fusion versus corpectomy and fusion for multilevel cervical spondylotic myelopathy: a minimum 5-year follow-up study

Purpose

We evaluated radiologic and clinical outcomes to compare the efficacy of anterior cervical discectomy and fusion (ACDF) and anterior corpectomy and fusion (ACCF) for multilevel cervical spondylotic myelopathy (CSM).

Methods

A total of 40 patients who underwent ACDF or ACCF for multilevel CSM were divided into two groups. Group A (n = 25) underwent ACDF and group B (n = 15) ACCF. Clinical outcomes (JOA and VAS scores), perioperative parameters (length of hospital stay, blood loss, operation time), radiological parameters (fusion rate, segmental height, cervical lordosis), and complications were compared.

Results

Both group A and group B demonstrated significant increases in JOA scores and significant decreases in VAS. Patients who underwent ACDF experienced significantly shorter hospital stays (p = 0.031), less blood loss (p = 0.001), and shorter operation times (p = 0.024). Both groups showed significant increases in postoperative cervical lordosis and achieved satisfactory fusion rates (88.0 and 93.3 %, respectively). There were no significant differences in the incidence of complications among the groups.

Conclusions

Both ACDF and ACCF provide satisfactory clinical outcomes and fusion rates for multilevel CSM. However, multilevel ACDF is associated with better radiologic parameters, shorter hospital stays, less blood loss, and shorter operative times.     

Mortality in patients with traumatic spinal cord injury: descriptive analysis of 62 deceased subjects

Study design

Retrospective study.

Objective

To investigate the causes of death in patients who were ≤50 years at the time of traumatic spinal cord injury (tSCI).

Setting

Convenience sample of a tertiary rehabilitation center.

Methods

All deceased patients with tSCI who survived a minimum of 10 years post-injury, were included. In addition, causes of death were compared between subjects surviving <10 years and ≥10 years. Neurological assessments were performed according to the American Spinal Injury Association scale. Data on causes of death were analyzed using the ICD-10 classifications. Differences were calculated using the Mann–Whitney and chi-square tests.

Results

A total of 100 patients, with 38 and 62 surviving <10 and ≥10 years, respectively, were included. No significant differences in causes of death were identified between these two groups. In patients surviving ≥10 years, paraplegia was associated with a higher life expectancy compared with tetraplegia, 34 and 25 years (p = 0.008), respectively, and the leading causes of death were septicemia (n = 14), ischemic heart disease (n = 10), neoplasms (n = 9), cerebrovascular diseases (n = 5), and other forms of heart diseases (n = 5). Septicemia, influenza/pneumonia, and suicide were the leading causes of death in tetraplegics, whereas ischemic heart disease, neoplasms, and septicemia were the leading causes of death in paraplegia.

Conclusion

Our monocentric study showed that in 62 deceased patients with SCI, the leading causes of death were septicemia, cardiovascular diseases, neoplasms, and cerebrovascular diseases. In addition, no significant differences were identified between causes of death among patients surviving <10 years and ≥10 years post-injury.     

Adherence with the National Cholesterol Education Program guidelines in men with chronic spinal cord injury

Objective

Describe the management of dyslipidemia and adherence to the National Cholesterol Educational Program (NCEP) guidelines in men with Spinal Cord Injury (SCI)

Research

Cross-sectional study of a consecutive sample of men with SCI presenting to a single site for coronary heart disease (CHD) risk assessment.

Participants/Methods

Men age 45 to 70 with traumatic SCI (ASIA A, B, and C) at least 10 years prior to participation in the study with no prior history of clinical CHD. Medical history, blood-pressure, and fasting lipid panel were used to calculate risk for CHD using NCEP guidelines and the Framingham Risk Score (FRS). Adherence to treatment recommendations and adequacy of control were assessed based on the NCEP guidelines.

Results

38 men were assessed; 15/38 (39.5%, 95% CI: 24.0–56.6%) had dyslipidemia, defined as an LDL-C above their LDL-C treatment threshold (n = 6) or being on treatment for dyslipidemia (n = 9, for a 60% treatment rate (9/15, 95% CI: 32.3–83.7%)). Of the 9 individuals on treatment, 6 (66.7%) met their treatment goals (for a 40% overall control rate (6/15, 95% CI: 16.3–67.7%)). Dyslipidemia was well controlled in low risk individuals, but control was less common in higher risk individuals.

Conclusions

Dyslipidemia is common in men age 45–70 with chronic SCI and no evidence of clinical cardiovascular disease. Rates of treatment and control of dyslipidemia in this population are far from optimal, especially among the intermediate- and high-risk groups.     

Dietary intake and adherence to the 2010 Dietary Guidelines for Americans among individuals with chronic spinal cord injury: A pilot study

Objective

To investigate dietary intake and adherence to the 2010 Dietary Guidelines for Americans in individuals with chronic spinal cord injury (SCI) and able-bodied individuals.

Design

A pilot study of dietary intake among a sample of individuals with SCI >1 year ago from a single site compared with able-bodied individuals.

Participants/methods

One hundred black or white adults aged 38–55 years old with SCI >1 year and 100 age-, sex-, and race-matched adults enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study. Dietary intake was assessed by the CARDIA dietary history. Linear regression analysis was used to compare dietary intake between the subjects with SCI and those enrolled in the CARDIA study. Further, adherence to the 2010 Dietary Guidelines for dairy, fruits, and vegetables, and whole-grain foods was assessed.

Results

Compared with CARDIA participants, participants with SCI consumed fewer daily servings of dairy (2.10 vs. 5.0, P < 0.001), fruit (2.01 vs. 3.64, P = 0.002), and whole grain foods (1.20 vs. 2.44 P = 0.007). For each food group, fewer participants with SCI met the recommended servings compared with the CARDIA participants. Specifically, the participants with SCI and in CARDIA who met the guidelines were, respectively: dairy, 22% vs. 54% (P < 0.001), fruits and vegetables 39% vs. 70% (P = 0.001), and whole-grain foods 8% vs. 69.6% (P = 0.001).

Conclusions

Compared with able-bodied individuals, SCI participants consumed fewer daily servings of fruit, dairy, and whole grain foods than proposed by the 2010 Dietary Guideline recommendations. Nutrition education for this population may be warranted.
