Trunk Function and Ischial Pressure Offloading in Individuals with Spinal Cord Injury

Objective: To determine if there is a relationship between trunk function and offloading of the ischial tuberosities in individuals with Spinal Cord Injury (SCI).

Design: Prospective cross-sectional evaluation.

Setting: Sub-acute rehabilitation hospital.

Participants: Fifteen non-ambulatory participants with complete or incomplete traumatic and non-traumatic SCI, American Spinal Injury Association Impairment Scale (AIS), Classification A-D.

Outcome Measures: Isometric trunk strength using a hand held dynamometer, the ability to reach using the multidirectional reach test and offloading times of the ischial tuberosities using a customized pressure mat.

Results: Participants who were able to engage in the multidirectional reach test were defined as “Reachers”, whereas individuals who were unable to engage in the multidirectional reach test were defined as “Non-Reachers”. Trunk strength was significantly higher in Reachers compared with Non-Reachers (P < 0.05). Offloading times over the left and right ischial tuberosities were lower in Non-Reachers when compared with Reachers, however the results were statistically significant only for offloading over the right ischial tuberosity (P < 0.05). There was no correlation between trunk strength and pressure offloading times for both groups.

Conclusions: Regardless of an individual's ability to engage in a reaching task, participants with spinal cord injury spent more time offloading the left ischial tuberosity compared with the right ischial tuberosity. The study highlights the need to identify factors that may contribute to offloading behavior in individuals with spinal cord injury who lack sufficient trunk strength.     

High-voltage electrical stimulation for the management of stage III and IV pressure ulcers among adults with spinal cord injury: demonstration of its utility for recalcitrant wounds below the level of injury

Context

Patients with spinal cord injury (SCI) have many factors that are associated with pressure ulcer formation, including paralysis, loss of sensation, poor nutrition, anemia, and skin maceration related to incontinence. Treatment of these ulcers involves relieving pressure, improving nutrition and skin hygiene, treating infections, removing necrotic tissues, and applying the appropriate dressings. However, some cases are not responsive to the above treatment. Electrical stimulation (ES) is thought to enhance soft tissue healing through promotion of protein synthesis, inhibition of bacterial growth, facilitation of epithelial tissue migration, improvement of blood flow, and tensile strength. This data is mainly based on evidence from animal studies and very few rigorously controlled studies conducted in humans.

Objective

To demonstrate the effectiveness of ES in the treatment of recalcitrant pressure ulcers.

Methods

Retrospective case series describing the care of adults with SCI and recalcitrant pressure ulcers. ES was applied directly into the wound bed: 60 minutes per session, 3–5 times per week; with an intensity of 100 milliamperes and a frequency of 100 pulses per second. Polarity was negative initially and was switched weekly. The amplitude and wave form were maintained throughout.

Results

The long-standing (11–14 months) pressure ulcers were completely healed after 7 to 22 weeks of treatment with high-voltage ES.

Conclusion/clinical relevance

This case series demonstrates the effectiveness of ES for enhanced healing of Stage III–IV ulcers otherwise unresponsive to standard wound care. Further study is needed to identify the most effective protocol for ES therapy in the treatment of recalcitrant pressure ulcers.     

Pneumocephalus Secondary To Cerebrospinal Fluid Leak Associated With A Lumbar Pressure Ulcer In A Man With Paraplegia

Abstract

Background: Pneumocephalus is a well-known condition following head trauma, but is uncommon in injuries or surgeries of the spine. Even more unusual is its occurrence in association with an eroding pressure ulcer and the subsequent penetration of the intrathecal space. This article reports such a case in a man with spinal cord injury. No previously reported cases of pneumocephalus and subarachnoid- pleural fistula secondary to a pressure ulcer are known.

Methods: Case presentation and literature review.

Findings: A 75-year-old man with with paraplegia, T2-level spinal cord injury, impairment score on the American Spinal Injury Association (ASIA) scale of ASIA A, and multiple pressure ulcers developed dural leak via a tract extending from a thoracolumbar ulcer to the T11 -T1 2 vertebrae. The resultant pneumocephalus was diagnosed based on acute neurologic symptoms and computed tomography scan. He underwent excision of the pressure ulcer and a T1 0 through L 1 laminectomy, during which the dural leak was located and sealed with fibrin glue.

Conclusion: Deep pressure ulcers overlying the spine should be managed aggressively to avoid life-threatening complications. Signs of meningeal irritation and/or mental status change in a patient with a deep posterior midline pressure ulcer with drainage suggestive of cerebrospinal fluid may indicate invasion of the intramedullary canal. Imaging studies are diagnostic of pneumocephalus and surgical closure of the spinal fluid leak is imperative when meningeal or other adverse neurologic signs are present.     

Lifestyle intervention for adults with spinal cord injury: Results of the USC–RLANRC Pressure Ulcer Prevention Study

Context/Objective: Medically serious pressure injuries (MSPrIs), a common complication of spinal cord injury (SCI), have devastating consequences on health and well-being and are extremely expensive to treat. We aimed to test the efficacy of a lifestyle-based intervention designed to reduce incidence of MSPrIs in adults with SCI.

Design: A randomized controlled trial (RCT), and a separate study wing involving a nonrandomized standard care control group.

Setting: Rancho Los Amigos National Rehabilitation Center, a large facility serving ethnically diverse, low income residents of Los Angeles County.

Participants: Adults with SCI, with history of one or more MSPrIs over the past 5 years: N=166 for RCT component, N=66 in nonrandomized control group.

Interventions: The Pressure Ulcer Prevention Program, a 12-month lifestyle-based treatment administered by healthcare professionals, largely via in-home visits and phone contacts.

Outcome Measures: Blinded assessments of annualized MSPrI incidence rates at 12 and 24 months, based on: skin checks, quarterly phone interviews with participants, and review of medical charts and billing records. Secondary outcomes included number of surgeries and various quality-of-life measures.

Results: Annualized MSPrI rates did not differ significantly between study groups. At 12 months, rates were .56 for intervention recipients, .48 for randomized controls, and .65 for nonrandomized controls. At follow-up, rates were .44 and .39 respectively for randomized intervention and control participants.

Conclusions: Evidence for intervention efficacy was inconclusive. The intractable nature of MSPrI threat in high-risk SCI populations, and lack of statistical power, may have contributed to this inability to detect an effect.

Pressure ulcers and acute risk factors in individuals with traumatic spinal fractures with or without spinal cord injuries: A prospective analysis of the National Spinal Column/Cord Injury Registry of Iran (NSCIR-IR) data

PurposeTo identify risk factors for developing pressure ulcers (PUs) in the acute care period of traumatic spinal fracture patients with or without spinal cord injuries (SCIs).MethodsData were collected prospectively in participating the National Spinal column/Cord Injury Registry of Iran (NSCIR-IR) from individuals with traumatic spinal fractures with or without SCIs, inclusive of the hospital stay from admission to discharge. Trained nursing staff examined the patients for the presence of PUs every 8 h during their hospital stay. The presence and grade of PUs were assessed according to the European Pressure Ulcer Advisory Panel classification. In addition to PU, following data were also extracted from the NSCIR-IR datasets during the period of 2015 – 2021: age, sex, Glasgow coma scale score at admission, having SCIs, marital status, surgery for a spinal fracture, American Spinal Injury Association impairment scale (AIS), urinary incontinence, level of education, admitted center, length of stay in the intensive care unit (ICU), hypertension, respiratory diseases, consumption of cigarettes, diabetes mellitus and length of stay in the hospital. Logistic regression models were used to estimate the unadjusted and adjusted odds ratio (OR) with 95% confidence intervals (CI).ResultsAltogether 2785 participants with traumatic spinal fractures were included. Among them, 87 (3.1%) developed PU during their hospital stay and 392 (14.1%) had SCIs. In the SCI population, 63 (16.1%) developed PU during hospital stay. Univariate logistic regression for the whole sample showed that marital status, having SCIs, urinary incontinence, level of education, treating center, number of days in the ICU, age, and Glasgow coma scale score were significant predictors for PUs. However, further analysis by multiple logistic regression only revealed the significant risk factors to be the treating center, marital status, having SCIs, and the number of days in the ICU. For the subgroup of individuals with SCIs, marital status, AIS, urinary incontinence, level of education, the treating center, the number of days in the ICU and the number of days in the hospital were significant predictors for PUs by univariate analysis. After adjustment in the multivariate model, the treating center, marital status (singles vs. marrieds, OR = 3.06, 95% CI: 1.55 – 6.03, p = 0.001), and number of days in the ICU (OR = 1.06, 95% CI: 1.04 – 1.09, p < 0.001) maintained significance.ConclusionsThese data confirm that individuals with traumatic spinal fractures and SCIs, especially single young patients who suffer from urinary incontinence, grades A-D by AIS, prolonged ICU stay, and more extended hospitalization are at increased risk for PUs; as a result strategies to minimize PU development need further refinement.     

A systematic review of electrical stimulation for pressure ulcer prevention and treatment in people with spinal cord injuries

Context

Electrical stimulation (ES) can confer benefit to pressure ulcer (PU) prevention and treatment in spinal cord injuries (SCIs). However, clinical guidelines regarding the use of ES for PU management in SCI remain limited.

Objectives

To critically appraise and synthesize the research evidence on ES for PU prevention and treatment in SCI.

Method

Review was limited to peer-reviewed studies published in English from 1970 to July 2013. Studies included randomized controlled trials (RCTs), non-RCTs, prospective cohort studies, case series, case control, and case report studies. Target population included adults with SCI. Interventions of any type of ES were accepted. Any outcome measuring effectiveness of PU prevention and treatment was included. Methodological quality was evaluated using established instruments.

Results

Twenty-seven studies were included, 9 of 27 studies were RCTs. Six RCTs were therapeutic trials. ES enhanced PU healing in all 11 therapeutic studies. Two types of ES modalities were identified in therapeutic studies (surface electrodes, anal probe), four types of modalities in preventive studies (surface electrodes, ES shorts, sacral anterior nerve root implant, neuromuscular ES implant).

Conclusion

The methodological quality of the studies was poor, in particular for prevention studies. A significant effect of ES on enhancement of PU healing is shown in limited Grade I evidence. The great variability in ES parameters, stimulating locations, and outcome measure leads to an inability to advocate any one standard approach for PU therapy or prevention. Future research is suggested to improve the design of ES devices, standardize ES parameters, and conduct more rigorous trials.     

Factors associated with upper extremity contractures after cervical spinal cord injury: A pilot study

Objective: To examine the prevalence of joint contractures in the upper limb and association with voluntary strength, innervation status, functional status, and demographics in a convenience sample of individuals with cervical spinal cord injury to inform future prospective studies.

Design: Cross-sectional convenience sampled pilot study.

Setting: Department of Veterans Affairs Research Laboratory.

Participants: Thirty-eight participants with cervical level spinal cord injury.

Interventions: Not applicable.

Main Outcome Measures: Contractures were measured with goniometric passive range of motion. Every joint in the upper extremity was evaluated bilaterally. Muscle strength was measured with manual muscle testing. Innervation status was determined clinically with surface electrical stimulation. Functional independence was measured with the Spinal Cord Independence Measure III (SCIM-III).

Results: Every participant tested had multiple joints with contractures and, on average, participants were unable to achieve the normative values of passive movement in 52% of the joints tested. Contractures were most common in the shoulder and hand. There was a weak negative relationship between percentage of contractures and time post-injury and a moderate positive relationship between percentage of contractures and age. There was a strong negative correlation between SCIM-III score and percentage of contractures.

Conclusions: Joint contractures were noted in over half of the joints tested. These joint contractures were associated with decreased functional ability as measured by the SCIM-III. This highlights the need the need for detailed evaluation of the arm and hand early after injury as well as continued monitoring of joint characteristics throughout the life course of the individual with tetraplegia.     

Autonomic Dysreflexia as a Complication of a Fecal Management System in a Man With Tetraplegia

Background/Objective:

To present a case of autonomic dysreflexia caused by the use of a fecal management system in a patient with tetraplegia.

Design:

Case report.

Setting:

Military rehabilitation center.

Results:

A man with tetraplegia had a fecal management system inserted to divert stool away from his sacral pressure ulcer to reduce contamination and infection risk. Two days later, he developed severe autonomic dysreflexia that improved after removal of the system.

Conclusions:

Autonomic dysreflexia, a life-threatening complication, has not been reported before as a side effect of a fecal management system. These systems should be used with caution in patients with high-level spinal cord injury.     

Report of practicability of a 6-month home-based functional electrical stimulation cycling program in an individual with tetraplegia

Background

Sedentarism is common among people with spinal cord injury (SCI). However, new technologies such as functional electrical stimulation cycles with internet connectivity may provide incentive by removing some of the limitations and external barriers.

Objective

To determine the effectiveness of a long-term home-based functional electrical stimulation lower extremities cycling (FES-LEC) program on exercise adherence, body composition, energy expenditure, and quality of life (QOL) in an adult with chronic tetraplegia.

Participant

A 53-year-old man, 33 years post-motor complete C4 SCI participated in FES-LEC in his home, three sessions per week for 24 weeks.

Methods

Exercise adherence was calculated as the percentage of performed cycling sessions relative to the recommended number of cycling sessions. Body composition was measured by dual-energy X-ray absorptiometry. Energy expenditure was measured using a COSMED K4b2 and QOL via the World Health Organization Quality of Life (WHO-QOL) Brief Questionnaire. Testing was performed before and after the 24-week exercise program.

Results

The participant cycled 59 out of a recommended 72 sessions which is an exercise adherence rate of 82%. Body composition displayed increases in total body lean mass (LM) with an increase of 3.3% and an increase in leg LM of 7.1%. Energy expenditure increased by 1.26 kcal/minute or greater than 200%. The physical and psychological domain scores of QOL increased by 25 and 4.5%, respectively.

Conclusion

This case study provides encouragement concerning the practicality of a home-based FES-LEC program for those with SCI.     

Comprehensive management of pressure ulcers in spinal cord injury: Current concepts and future trends

Abstract

Pressure ulcers in spinal cord injury represent a challenging problem for patients, their caregivers, and their physicians. They often lead to recurrent hospitalizations, multiple surgeries, and potentially devastating complications. They present a significant cost to the healthcare system, they require a multidisciplinary team approach to manage well, and outcomes directly depend on patients' education, prevention, and compliance with conservative and surgical protocols. With so many factors involved in the successful treatment of pressure ulcers, an update on their comprehensive management in spinal cord injury is warranted. Current concepts of local wound care, surgical options, as well as future trends from the latest wound healing research are reviewed to aid medical professionals in treating patients with this difficult problem.     

Diagnostic Pitfalls: Case Report Of Scurvy In A Man With Spinal Cord Injury

Abstract

Background: A 49-year-old man with spinal cord injury (SCI) developed a progressive purpuric rash and painful swelling of the lower extremities, in addition to chronic purpura over the ischial tuberosities.

Design: Case report

Findings: Following an extensive workup for presumed vasculitis, a skin biopsy showed evidence of scurvy. Risk facto rs for scurvy included limited means of transportation, living alone, and alcohol abuse.

Conclusions: Scurvy can be confused with disorders common among SCI patients, such as vasculitis, venous thrombosis, occult trauma, and pressure injury. Scurvy should be considered in the differential diagnosis of skin lesions, especially in individuals who abuse alcohol and live alone.     

Effectiveness of a multi‐layer foam dressing in preventing sacral pressure ulcers for the early acute care of patients with a traumatic spinal cord injury: comparison with the use of a gel mattress

Individuals with spinal cord injury are at risk of sacral pressure ulcers due to, among other reasons, prolonged immobilisation. The effectiveness of a multi‐layer foam dressing installed pre‐operatively in reducing sacral pressure ulcer occurrence in spinal cord injured patients was compared to that of using a gel mattress, and stratified analyses were performed on patients with complete tetraplegia and paraplegia. Socio‐demographic and clinical data were collected from 315 patients admitted in a level‐I trauma centre following a spinal cord injury between April 2010 and March 2016. Upon arrival to the emergency room and until surgery, patients were transferred on a foam stretcher pad with a viscoelastic polymer gel mattress (before 1 October 2014) or received a multi‐layer foam dressing applied to their sacral‐coccygeal area (after 1 October 2014). The occurrence of sacral pressure ulcer during acute hospitalisation was similar irrespective of whether patients received the dressing or the gel mattress. It was found that 82% of patients with complete tetraplegia receiving the preventive dressing developed sacral ulcers as compared to only 36% of patients using the gel mattress. Although multi‐layer dressings were suggested to improve skin protection and decrease pressure ulcer occurrence in critically ill patients, such preventive dressings are not superior to gel mattresses in spinal cord injured patients and should be used with precaution, especially in complete tetraplegia.     

Electrical Perceptual Threshold Testing: A Validation Study

Background/Objective: To investigate inter-rater and intra-rater reliability of electrical perceptual threshold (EPT) testing in assessing somatosensory function in healthy volunteers.

Study Design: Prospective experimental.

Setting: Hospital-based spinal cord injuries unit.

Methods: Cutaneous electrical stimulation of 4 dermatomes at ASIA sensory key points (C3, T1, L3, and S2) was performed on 40 control subjects. The lowest ascending stimulus intensity at which sensation was perceived was recorded as the EPT. Mean EPT values for each dermatome, as determined by 2 testers at 2 time points, were examined and plotted against a normative template. Differences and associations between intra- and inter-rater measurements and left-right measurements were studied. EPT results for 2 people with spinal cord injuries were also examined.

Results: EPT measurements from left and right sides, obtained from the 2 time points and 2 testers, were found to be strongly associated, with the exception of left and right side measurements at the S2 dermatome. No significant differences in the mean EPT for tester or time period were found. The intra- and inter-rater reliability was good for all dermatomes tested. Mean EPT measurements fell within the range of a normative template at each of the 4 dermatomes tested.

Conclusion: EPT is an objective, reproducible, and quantifiable method of assessing sensation in a control group. However, caution should be applied in certain dermatomes such as S2, where there was large variation between left and right side measurements.

Functional electrical stimulation cycling in youth with spinal cord injury: A review of intervention studies

Context

Preliminary research suggests that functional electrical stimulation cycling (FESC) might be a promising intervention for youth with spinal cord injury (SCI).

Objective

To review the evidence on FESC intervention in youth with SCI.

Methods

Systematic literature searches were conducted during December 2012. Two reviewers independently selected titles, abstracts, and full-text articles. Of 40 titles retrieved, six intervention studies met inclusion criteria and were assessed using American Academy for Cerebral Palsy and Developmental Medicine Levels of Evidence and Conduct Questions for Group Design.

Results

The study results were tabulated based on levels of evidence, with outcomes categorized according to the International Classification of Functioning, Disability, and Health framework. Evidence from the six included studies suggests that FESC is safe for youth with SCI, with no increase in knee/hip injury or hip displacement. Results from one level II randomized controlled trial suggest that a thrice weekly, 6-month FESC program can positively influence VO₂ levels when compared with passive cycling, as well as quadriceps strength when compared with electrical stimulation and passive cycling.

Conclusions

FESC demonstrates limited yet encouraging results as a safe modality to mitigate effects of inactivity in youth with SCI. More rigorous research involving a greater number of participants is needed before clinicians can be confident of its effectiveness.     

The relationship of pressure ulcers, race, and socioeconomic conditions after spinal cord injury

Objective:

To identify risks factors associated with pressure ulcers (PrU) after spinal cord injury (SCI) by examining race and indicators of socioeconomic status (measured by income and education). We hypothesize African Americans will have a greater risk for PrUs than whites, but this relationship will be mediated by the 2 socioeconomic status indicators.

Design:

Cohort study.

Setting:

A large rehabilitation hospital in the southeastern US.

Participants:

1,466 white and African American adults at least 1-year post-traumatic SCI.

Outcome Measures:

(a) PrUs in the past year, (b) current PrU, (c) surgery to repair a PrU since injury.

Results:

In preliminary analyses, race was significantly associated with having a current PrU and with having surgery to repair a PrU since injury. In multivariable analyses, the relationships of PrU with having a current PrU and with having surgery to repair a PrU were both mediated by income and education such that the relationships were no longer significant. Lower income was associated with increased odds of each PrU outcome. After controlling for other variables in the model, education was associated with increased odds of having a current PrU.

Conclusion:

These findings help clarify the relationships between race and socioeconomic status with PrUs after SCI. Specifically, a lack of resources, both financial and educational, is associated with worse PrU outcomes. These results can be used by both providers and policy makers when considering prevention and intervention strategies for PrUs among people with SCI.     

The Thoracic Suspension Orthosis-A Seating Option For Patients With Pressure Ulcers

Abstract

Background/Objective: For patients with pressure ulcers, wound healing and prevention are important steps in reducing disability. Ulcers that fail to heal adequately may interfere with normal sitting. By relieving pressure, the thoracic suspension orthosis (TSO) may allow some patients with recurrent pressure ulcers to return to sitting and sit for longer periods.

Methods: In this retrospective case series, 6 patients with chronic pressure ulcers were managed with TSO. Each patient had at least one of the following: (1) severe, non-healing pressure ulcers unresponsive to standard therapy, (2) recurrent ulcers requiring multiple surgeries, (3) chronic pain associated with sitting, or (4) bilateral lower extremity amputation resulting in instability or ischial pain in the seated position.

Results: Each participant had a favorable functional outcome. Patients were able to resume modified sitting. Others were able to sit for longer periods. Some have used the TSO for long-term management.

Conclusions: A TSO is an additional seating option for patients with chronic pressure ulcer, chronic pain associated with sitting, or bilateral lower extremity amputation. It is recommended after less restrictive, conservative measures have failed. In some patients, it has been used in lieu of extreme surgical measures.
