The Relationships Among Serum Lipid Levels,Adiposity, And Depressive Symptomatology In Persons Aging With Spinal Cord Injury

Abstract

Background: Cardiovascular disease (CVD) appears to occur prematurely in persons with spinal cord injury (SCI). Stress may play a significant role in the development of CVD. Depression is the most common form of stress complicating the care of persons with SCI.

Methods: In 188 persons with SCI, 46% with tetraplegia and 54% with paraplegia, the relationship between depression and the serum lipid profile was studied. Depression was measured by the Older Adult Health and Mood Questionnaire (OAHMQ) for persons with disability. Total cholesterol, high density lipoprotein (HDL) and low density lipoprotein (LDL) cholesterol and triglycerides were measured; body mass index (BMI) was computed and percent body fat was determined by dual-energy x-ray absorptiometry (DXA).

Results: Depression and level of SCI were found to have significant interactive effects on serum lipid levels. Serum total and LDL cholesterol, as well as triglycerides, were all higher among persons with paraplegia who were depressed compared to those who were not depressed. This was not found in persons with tetraplegia. Inverse relationships were evident between serum triglycerides and HDL cholesterol levels. Persons with paraplegia who were depressed had significantly more adiposity than those not depressed. BMI correlated directly with serum triglycerides and indirectly with serum HDL cholesterol.

Conclusion: Depression appears to be a strong determinant of adverse lipid profiles in patients with paraplegia. The association between depression and adiposity in these patients compounds the risk for cardiovascular disease.     

Shoulder Emg During Depression Raise In Men With Spinal Cord Injury: The Influence Of Lesion Level

Abstract

Background & Objective: The depression-style raise maneuver is commonly performed by persons with spinal cord injury (SCI) to relieve skin pressures and avoid skin ulceration. The demands of this critical activity, however, are not fully documented for individuals with higher spinal cord lesions. The purpose of this investigation was to determine the influence of SCI lesion level on shoulder muscle activity during a depression raise maneuver.

Experimental Design: Sample of convenience, group comparison.

Methods: Fine-wire intramuscular electrodes recorded electromyographic (EMG) activity from 1 2 shoulder muscles in 57 men with SCI while they performed depression raises (C6 tetraplegia, n = 1 0; C7 tetraplegia, n = 1 8; high paraplegia, n = 1 6; low paraplegia, n = 1 3). EMG intensity was normalized to a manual muscle test (MMT) effort.

Results: For persons with paraplegia and C7 tetraplegia, dominant EMG activity was recorded from latissimus dorsi, sternal pectoralis major, and triceps muscles (31 %-69% MMT) . Tetraplegic groups had significantly greater anterior deltoid activity (C6 = 53%, C7 = 22% MMT) than that recorded in paraplegic groups (high paraplegia = 1 0%, low paraplegia = 3% MMT). Participants with tetraplegia also had increased infraspinatus activity (C6 = 50%, C7 = 32% MMT) compared with participants with low paraplegia (7% MMT). All other muscles had low or very low EMG activity during the depression raise.

Conclusions: Persons with tetraplegia lack normal strength of the primary muscles used by participants with paraplegia for the depression raise (ie, latissimus dorsi, sternal pectoralis major, and triceps muscles) . Although increased anterior deltoid activation assisted with elbow extension, it potentially contributes to glenohumeral joint impingement. Alternate methods of pressure relief should be considered for persons with tetraplegia.

Shoulder Muscular Demand During Lever-Activated Vs Pushrim Wheelchair Propulsion In Persons With Spinal Cord Injury

Background/Objective: The high demand on the upper limbs during manual wheelchair (WC) use contributes to a high prevalence of shoulder pathology in people with spinal cord injury (SCI). Leveractivated (LEVER) WCs have been presented as a less demanding alternative mode of manual WC propulsion. The objective of this study was to evaluate the shoulder muscle electromyographic activity and propulsion characteristics in manual WC users with SCI propelling a standard pushrim (ST) and LEVER WC design.

Methods: Twenty men with complete injuries (ASIA A or B) and tetraplegia (C6, n = 5; C7, n = 7) or paraplegia (n = 8) secondary to SCI propelled STand LEVER WCs at 3 propulsion conditions on a stationary ergometer: self-selected free, self-selected fast, and simulated graded resistance. Average velocity, cycle distance, and cadence; median and peak electromyographic intensity; and duration of electromyography of anterior deltoid, pectoralis major, supraspinatus, and infraspinatus muscles were compared between LEVER and ST WC propulsion .

Results: Sign ificant decreases in pectoralis major and supraspinatus activity were recorded during LEVER compared with ST WC propulsion. However, anterior deltoid and infraspinatus intensities tended to increase during LEVER WC propulsion. Participants with tetraplegia had similar or greater anterior deltoid, pectoralis major, and infraspinatus activity for both ST and LEVER WC propulsion compared with the men with paraplegia.

Conclusions: Use of the LEVER WC reduced and shifted the shoulder muscular demands in individuals with paraplegia and tetraplegia. Further studies are needed to determine the impact of LEVER WC propulsion on long-term shoulder function.     

Comparison of Lung Volume Measurements In Individuals With Spinal Cord Injury By Two Different Methods

Abstract

Background/Objective: Few detailed studies have been performed among subjects with spinal cord injury (SCI) using whole body plethysmography for measurement of static lung volumes. Because abdominal gas volumes and respiratory patterns among subjects with varying Ieveis of SCI may differ significantly from able-bodied individuals, methodological concerns related to this technique could conceivably Iead to inaccuracies in lung volume measurements. The purpose of this study was to compare lung volume parameters obtained by whole body plethysmography with those determined by the commonly used nitrogen washaut technique among individuals with SCI.

Participants: Twenty-nine clinically stable men, 14 with chronic tetraplegia (injury C4-C7) and 15 with paraplegia (injury below T5) participated in the study.

Methods: Lung volumes were obtained using whole body plethysmography and the open-circuit nitrogen washout technique. Within both study groups, data were evaluated by the paired Student’st test and by determination of correlation coefficients.

Results: No statistically significant differences for any lung volume parameter were found within either group. ln subjects with tetraplegia on paraplegia, respectively, strong correlation coefficients were found for measurements of totallung capacity (.8 6 and .97), functional residual capacity (.87 and .96), and residual volume (.77 and .85).

Conclusion: These findings indicate that body plethysmography is a valid technique for determining lung volumes among subjects with SCI. Because airway resistance measurements can also be obtained du ring same study sessions for assessment of airway caliber and bronchial responsiveness, body plethysmography is a useful tool for examining multiple aspects of pulmonary physiology in this population.     

Lipid Profiles of Persons With Paraplegia and Tetraplegia: Sex Differences

Abstract

Background/Objective: To examine the lipoprotein profiles of men and women with paraplegia and tetraplegia. Impairment of the sympathetic nervous system (dependent on the level of injury) and the extent of physical capacity and activity were correlated with the lipid profile in men with spinal cord injury (SCI). Sex-related differences of the lipoprotein profiles could be found in nondisabled and premenopausal women with SCI mainly because of the different effects of sexual hormones.

Methods: Lipoprotein profiles of 112 participants with SCI (32 premenopausal women, 80 men) were analyzed and correlated to sex, lesion level, and physical performance capacity.

Results: Women with tetraplegia or paraplegia showed significantly higher levels of high-density lipoprotein and lower ratios of total cholesterol to high-density lipoprotein-cholesterol compared with men with corresponding lesion levels, without a difference in peak oxygen consumption. Concentrations of very-low-density lipoproteins were lower in women with paraplegia than in men with paraplegia, no differences were found in total cholesterol, low-density lipoprotein-cholesterol, and triglycerides. Sexindependent elevations in total cholesterol and low-density lipoprotein-cholesterol were associated with paraplegia, and sex-independent elevations in triglyceride levels were associated with tetraplegia.

Conclusions: Persons with SCI showed sex-related differences in their lipoprotein profiles. Independent of physical fitness, the lipoprotein profile of premenopausal women with SCI did not exhibit the adverse lipoprotein characteristics observed in men with SCI, probably because of the influence of sexual hormones independent of lesion level.     

Reliability and Repeatability of the Motor and Sensory Examination of the International Standards for Neurological Classification of Spinal Cord Injury

Abstract

Objective: To determine the reliability and repeatability of the motor and sensory examination of the International Standards for Classification of Spinal Cord Injury (SCI) in trained examiners.

Participants/Methods: Sixteen examiners (8 physicians, 8 physical therapists) with clinical SCI experience and 16 patients participated in a reliability study in preparation for a clinical trial involving individuals with acute SCI. After a training session on the standards, each examiner evaluated 3 patients for motor, light touch (LT), and pin prick (PP). The following day, 15 examiners reevaluated one patient. Interrater reliability was determined using intraclass correlation coefficients (1-way, random effects model). Intrarater reliability was determined using a 2-way random effects model. Repeatability was determined using the method of Bland and Altman.

Results: Patients were classified as complete tetraplegia (n = 5), incomplete tetraplegia (n = 5), complete paraplegia (n = 5), and incomplete paraplegia (n = 1). Overall, inter-rater reliability was high: motor = 0.97, LT = 0.96, PP = 0.88. Repeatability values were small in patients with complete SCI (motor < 2 points, sensory < 7 points) but large for patients with incomplete SCI. Intra-rater reliability values were > 0.98 for patients with complete SCI.

Conclusions: The summed scores for motor, LT, and PP in subjects with complete SCI have high interrater reliability and small repeatability values. These measures are appropriately reliable for use in clinical trials involving serial neurological examinations with multiple examiners. Further research in subjects with incomplete SCI is needed to determine whether repeatability is acceptably small.     

The impact of level of injury on patterns of cognitive dysfunction in individuals with spinal cord injury

Context: While it is well recognized that physical and physiological changes are more prominent in individuals with higher neurologic levels of spinal cord injury (SCI), the impact of level of lesion on cognition is less clear.

Design: Cross-sectional, 3-group.

Setting: Non-profit rehabilitation research foundation.

Participants: 59 individuals with SCI (30 with tetraplegia, 29 with paraplegia) and 30 age-matched healthy controls (HC).

Interventions: None.

Outcome Measures: Neuropsychological tests in the domains of attention, working memory, processing speed, executive control, and learning and memory.

Results: Results indicated significantly lower test performance in individuals with paraplegia on new learning and memory testing compared to HC. In contrast, compared to HC the group with tetraplegia, showed a significantly impaired performance on a processing speed task, and both the tetraplegia and the paraplegia groups were similarly impaired on a verbal fluency measure. SCI groups did not differ on any cognitive measure.

Conclusion: Individuals with SCI may display different patterns of cognitive performance based on their level of injury.     

Physiotherapy Secretion Removal Techniques in People With Spinal Cord Injury: A Systematic Review

Abstract

Objective: To address whether secretion removal techniques increase airway clearance in people with chronic spinal cord injury (SCI).

Data Sources and Study Selection: MEDLINE/PubMed, CINAHL, EMBASE, and PsyclNFO were searched from inception to May 2009 for population keywords (spinal cord injury, paraplegia, tetraplegia, quadriplegia) paired with secretion removal-related interventions and outcomes. Inclusion criteria for articles were a research study, irrespective of design, that examined secretion removal in people with chronic SCI published in English.

Review Methods: Two reviewers determined whether articles met the inclusion criteria, abstracted information, and performed a quality assessment using PEDro or Downs and Black criteria. Studies were then given a level of evidence based on a modified Sackett scale.

Results: Of 2,416 abstracts and titles retrieved, 24 met the inclusion criteria. Subjects were young (mean, 31 years) and 84% were male. Most evidence was level 4 or 5 and only 2 studies were randomized controlled trials. Three reports described outcomes for secretion removal techniques in addition to cough, whereas most articles examined the immediate effects of various components of cough. Studies examining insufflation combined with manual assisted cough provided the most consistent, high-level evidence. Compelling recent evidence supports the use of respiratory muscle training or electrical stimulation of the expiratory muscles to facilitate airway clearance in people with SCI.

Conclusion: Evidence supporting the use of secretion removal techniques in SCI, while positive, is limited and mostly of low level. Treatments that increase respiratory muscle force show promise as effective airway clearance techniques.     

Five-Year Longitudinal Bone Evaluations In Individuals With Chronic Complete Spinal Cord Injury

Background/Objectives:Knowledge of spinal cord injury (SCI) bone changes has been derived primarilythrough cross-sectional studies, many of which are controvertible. Longitudinal studies are sparse, and longtermlongitudinal chronic studies are unavailable. The objective of this study was to provide a clearerperception of chronic longitudinal bone variations in people with complete SCI.

Methods:Bone status of 31 individuals with chronic, complete SCI was assessed twice using dual-energy xrayabsorptiometry at an average interval of 5.06 ± 0.9 years. Because the sample of women was small (4),the primary analyses of change and comparisons of those with paraplegia vs tetraplegia were confined to themale participants.

Results: Spine Z-scores showed a significant increase (P < 0.0001 ). The average Z-scores, initial and followup,were within the normal range. Hip Z-scores also showed a significant increase (P < 0.0001 ), and hipbone mineral density (BMD) increased in 48% of the participants. Knee BMD and lower extremity total bonemineral showed significant decreases (P < 0.003 and P < 0.02, respectively), but increases were seen in 33% and 26% at the respective sites. Individuals with tetraplegia had significantly lower values across all regions(P < 0.0001 ), and changes were significantly different compared with paraplegia (P < 0.0001 ). Bone valuesand changes in men vs women, despite the small sample of women, showed highly significant differences(P < 0.003?0.002).

Conclusion:Chronic effects of complete SCI do not exclusively result in continued loss of BMD or a staticstate of lowered BMD; gain in BMD may occur. The nature and magnitude of the effects of complete SCI on BMD vary by site, with sex and level of injury, which has implications for treatment and its assessment.     

The International Standards for Neurological Classification of Spinal Cord Injury: Intra-Rater Agreement of Total Motor and Sensory Scores in the Pediatric Population

Background: The International Standards for Neurological Classification of Spinal Cord Injury (ISCSCI) is the gold standard for evaluating and classifying the neurological consequence of spinal cord injury (SCI). Objective: To determine the within-rater agreement for total scores of light touch (LT), pin prick (PP), and total motor (TM) in children and youth.

Design: Part of a larger cross-sectional study to determine the intra-rater reliability of the standards when applied to children and youth.

Participants/Methods: A total of 187 subjects participated in 2 repeated examinations performed by the same rater. A total of 7 raters participated in this study. Intraclass correlations coefficients (ICCs), with 95% Cl were calculated to determine agreement between the 2 examinations for LT, PP, and TM.

Results: With the exception of subjects younger than 6 years, agreement on repeated total PP, LT, and TM scores were good to excellent, as shown by ICC values of 0.92 or higher. Although agreement was high for the youngest age group for LT (ICC = 0.920), PP (ICC = 0.957), and TM (ICC = 0.971), all of the lower 95% Cl values fell well below 0.66, indicating poor precision. All subgroups had good to high agreement for total PP, LT, and TM scores, as indicated by ICC values of 0.87 and higher. There were lower 95% Cl (LCI) values for the 6- to 11-year-old group with incomplete paraplegia due to the low number of subjects in that subgroup (N = 4). The LCI values were poor for PP for the subgroups with 6- to 11-year-olds with incomplete tetraplegia (LCI = 0.675) and the 12- to 15-year-old group with incomplete paraplegia (LCI = 0.707) and for TM for 16- to 21-year-old group with complete paraplegia (LCI = 0.706).

Conclusions: In children as young as 6 years, within-rater agreement on LT, PP, and TM exceeded recommended values for clinical measures. With the exception of 6- to 11-year-olds with incomplete injuries, type of injury and severity of injury were not factors in agreement. Although more work is needed to define the lower age limit in which the ISCSCI have utility, these data represent growing evidence supporting the use of the ISCSCI when evaluating the neurological consequence of SCI in children.     

Bisphosphonate Use in Acute and Chronic Spinal Cord Injury: A Systematic Review

Background/Objective: Bone density loss occurs rapidly after traumatic spinal cord injury (SCI) and is associated with low-energy fractures below the level of injury, commonly occurring around the knee. Bisphosphonates have been tested as potential agents to prevent bone loss after SCI, but no guidelines exist for clinical use of bisphosphonates in these patients. The objective of this study was to systematically review and evaluate evidence quality in studies of bisphosphonate use in patients with post-treatment follow-up of sublesional bone mineral density.

Methods: Literature search in MEDLINE/PubMed and ISI database using key words bisphosphonates, spinal cord injury, quadriplegia, paraplegia, and tetraplegia.

Results: The search identified 6 experimental studies and 1 quasi-experimental study of bisphosphonate therapy in patients with acute and chronic SCI. The studies were small and of fair or poor quality, and none included fracture outcomes. Mild attenuation of bone density loss with acute administration of bisphosphonates after SCI was found at some measurement sites but was not always maintained during follow-up.

Conclusions: Data were insufficient to recommend routine use of bisphosphonates for fracture prevention in these patients. Current studies are limited by heterogeneity of patient populations and outcome measures. Uniform bone density measurement sites with rigorous quality control and compliance monitoring are needed to improve reliability of outcomes. Future studies should address specific populations (acute or chronic SCI) and should assess fracture outcomes.     

Evaluation of the Effects of Compression Stockings Using Venous Plethysmography in Persons With Spinal Cord Injury

Abstract

Background/Objective: To examine the effect of graduated compression stockings (GCS) on the properties of the venous vascular system, as characterized by venous capacitance (VC) and venous outflow (VO), in the lower extremities of individuals with spinal cord injury (SCI), according to injury level.

Methods: Nine male subjects with SCI (5 with low paraplegia [LP], 4 with high paraplegia [HP]) performed 2 plethysmography tests: with and without graduated compression knee-length stockings (pressure of 21 mm/Hg). The VC, VO, and cardiovascular parameters (heart rate and blood pressure) were evaluated with and without GCS.

Results: The VC and VO were lower in patients with HP than in those with LP. For all subjects, VC was significantly lower (-14%) with GCS than without (1.77 ± 1.18 vs 1.53 ± 1.09 vol%, P < 0.01). On the contrary, VO did not differ significantly when wearing or not wearing GCS.

Conclusions: This study demonstrated that 21-mm/Hg knee-length GCS are sufficient to prevent venous distension in individuals with SCI, even those with longstanding paraplegia, by significantly decreasing venous capacitance. This intervention may help to prevent deep vein thrombosis.     

Higher dietary intake of vitamin D may influence total cholesterol and carbohydrate profile independent of body composition in men with Chronic Spinal Cord Injury

Study Design: A case-control design.

Objectives: To determine the effects of dietary vitamin D intake on insulin sensitivity (Si), glucose effectiveness (Sg), and lipid profile in individuals with spinal cord injury (SCI).

Methods: 20 male, paraplegic (T3-L1) with chronic (> one year) motor complete SCI (AIS A or B) were recruited. Three-day dietary records were analyzed for dietary vitamin D (calciferol), and participants were assigned to one of two groups, a high vitamin D intake group and a low vitamin D intake group based on the mid-point of vitamin D frequency distribution. Individuals in both groups were matched based on age, weight, time since injury and level of injury. Sg, Si and lipid profiles were measured of the two groups.

Results: The high vitamin D group had an average intake of 5.33?±?4.14 mcg compared to low vitamin D group, 0.74?±?0.24 mcg. None of the 20 participants met the recommended guidelines for daily vitamin D intake. The higher vitamin D group had a significantly lower (P?=?0.035) total cholesterol (148.00?±?14.12 mg/dl) than the lower vitamin D group (171.80?±?36.22 mg/dl). Vitamin D adjusted to total dietary intake was positively correlated to improvement in Si and Sg (P<0.05).

Conclusion: The findings suggest that persons with SCI consume much less than the recommended guidelines for daily vitamin D intake. However, a higher dietary intake of vitamin D may influence total cholesterol and carbohydrate profile as demonstrated by a significant decrease in total cholesterol and improvement in glucose homeostasis independent of body composition changes after SCI.     

Perceived Quality of Care and Outcomes Following Spinal Cord Injury: Minority Status In The Context Of Multiple Predictors

Abstract

Objective: T o determine whether patients with spinal cord injury (SCI) who are members of minority groups experience a disadvantage with regard to quality of care, and investigate predictors of perceived quality of care and indicators of outcome.

Design: Correlational analysis of longitudinal data.

Sample: One hundred and forty-three individuals with SCI in the first year following injury (43.3 % tetraplegia, 56.7% paraplegia; 53.6% of total had complete injuries).

Setting: Hospital and post discharge (usually outpatient) care at 3 SCI model systems.

Main Outcome Measures: Perceived quality of acute, rehabilitative, and continuing care rated by patients according to standardformat. Objective indicators of amount of care (eg, length of stay [LOS], charges) and outcomes (eg, medical complications,Functional lndependence Measure [FIM] scores, a life satisfaction measure [the Diener Scale], and the Craig Handicap and Reporting Technique [CHART; a community participation scale]).

Results: Minorities did not report statistically significant differences in perceived quality of care or other indicators (eg, amount ofcare, medical complications, FIM gain, life satisfaction, and CHART scores) compared with other groups. Severity ofinjury affected LOS and activity outcomes. Satisfaction with medical care before the injury significantly predicted perceived quality of acute hospital care, inpatient rehabilitation, and continuing ca re (P < 0.03, 0.02, and 0.02, respectively) .

Conclusion: A number of factors may affect variations in perceived quality of care and outcomes, but ethnicity is not always the most important predictor. Asking patients about their satisfaction with previous care can assist in distinguishing satisfaction with currentcare from pre-existing biases.     

Profile of patients with spinal cord injuries in Kwazulu-Natal,South Africa: Implications for vocational rehabilitation

Objectives: To describe the demographic and socio-economic profiles, and injury related characteristics of people who sustain SCIs in KZN in order to provide baseline information to instigate a model that guides employment outcomes amongst PLWSCI.

Design: Retrospective analysis of medical files was done.

Setting: King Dinizulu Hospital Spinal Unit (KDHSU), this being the biggest provider of acute care for people who sustain SCI in KwaZulu-Natal and the Eastern Cape Provinces, South Africa was the setting for our study.

Participants: Medical files of individuals who sustained SCI between 2009 and 2012 were perused (n?=?1049) were perused and 188 met the inclusion criteria.

Outcome Measures: Key information from the KDHSU patient’s files were extracted using a tool developed using literature and the international spinal cord injury core data set.

Results: The average annual incidence rate was 12.3 per 100 000 population. The male to female ratio was 6:4 with the mean age of 36.69 years, ranging from 16-64. Out of those employed (34%), 72% were working fulltime, mostly in the service industry (31%) and 59% were classified as laborers. The majority (61%) of the participants completed high school. The major cause of SCI was non-traumatic (54%) and 66% were classified as incomplete (ASIA). Furthermore, 80% were classified as paraplegia and 19% tetraplegia. The mean LOS was 42.9 days, ranging from 1-764 days, influenced by level of injury, completeness and classification of injury and surgical intervention.

Conclusion: The profile of SCI in KwaZulu-Natal is slightly different when compared to other provinces in South Africa and the rest of Africa. There is a need to use epidemiological information (including factors that influence employment) to develop rehabilitation models to guide employment outcomes amongst people living with spinal cord injuries in KZN.     

Sleep disordered breathing in spinal cord injury: A systematic review

Context: Spinal cord injury commonly results in neuromuscular weakness that impacts respiratory function. This would be expected to be associated with an increased likelihood of sleep-disordered breathing.

Objective: (1) Understand the incidence and prevalence of sleep disordered breathing in spinal cord injury. (2) Understand the relationship between injury and patient characteristics and the incidence of sleep disordered breathing in spinal cord injury. (3) Distinguish between obstructive sleep apnea and central sleep apnea incidence in spinal cord injury. (4) Clarify the relationship between sleep disordered breathing and stroke, myocardial infarction, metabolic dysfunction, injuries, autonomic dysreflexia and spasticity incidence in persons with spinal cord injury. (5) Understand treatment tolerance and outcome in persons with spinal cord injury and sleep disordered breathing.

Methods: Extensive database search including PubMed, Cochrane Library, CINAHL and Web of Science.

Results: Given the current literature limitations, sleep disordered breathing as currently defined is high in patients with spinal cord injury, approaching 60% in motor complete persons with tetraplegia. Central apnea is more common in patients with tetraplegia than in patients with paraplegia.

Conclusion: Early formal sleep study in patients with acute complete tetraplegia is recommended. In patients with incomplete tetraplegia and with paraplegia, the incidence of sleep-disordered breathing is significantly higher than the general population. With the lack of correlation between symptoms and SDB, formal study would be reasonable. There is insufficient evidence in the literature on the impact of treatment on morbidity, mortality and quality of life outcomes.     

Gastric Dysmotility After Abdominal Surgery in Persons With Cervical Spinal Cord Injury: A Case Series

Abstract

Background: Spinal cord injury (SCI) has been found to affect the physiology of the gastrointestinal tract. Changes in gastric motility occur in tetraplegia because of dissociation of antral and duodenal motility. Among individuals with high-level tetraplegia, antral quiescence has been hypothesized as a manifestation of autonomic dysreflexia after surgery. This case series shows the issues with gastric hypomotility after gastrointestinal surgery in tetraplegic patients with tetraplegia, including management strategies.

Objective: To report 3 patients with complete high cervical SCI who developed gastroparesis after abdominal surgery and discuss the effect of autonomic dysfunction on gastric motility.

Methods: Retrospective chart review of 3 cases.

Results: Gastroparesis occurred after abdominal surgery in 3 patients with C4 American Spinal Injury Association (ASIA) A tetraplegia and seemed to be a sign of autonomic hyperreflexia caused by postoperative pain. Management was challenging because it consisted of balancing of appropriate pain medication and dealing with absorption issues and dysmotility. Often gastric motility agents were not effective in improving gastric emptying. However, increased use of pain medication improved gastric emptying, which supports the hypothesis that this issue represents gastric dysfunction from autonomic hyperreflexia.

Conclusions: In persons with complete cervical SCI who have undergone abdominal surgery, postoperative gastroparesis can be a manifestation of pain. This may occur as the excessive sympathetic response from autonomic hyperreflexia inhibits distal antral activity. Thus, treatment of postoperative gastroparesis should focus on improved pain control to decrease excessive splanchnic sympathetic output and circulating norepinephrine.
