Chronic pain after spinal cord injury: a survey of practice in UK spinal injury units.

OBJECTIVE: To determine current practice regarding assessment and management of patients with chronic pain after spinal cord injury (SCI) in the UK. METHODS: A postal questionnaire sent to the medical directors of the 12 spinal injury units in the UK. RESULTS: A response was received from nine of the 12 units. Chronic pain was felt to be a significant problem amongst patients with SCI, with inconsistent opinion between respondents regarding prevalence, aetiology and classification of chronic pain after spinal cord injury. Only one unit had established protocols for the investigation and management of pain, and most units felt that guidelines would be useful. Most felt that there was a need for further information on the subject. CONCLUSION: Our survey has demonstrated the uncertainty that exists amongst specialists dealing with pain after SCI, and emphasised the need for more research into the problem.

Flexible cystoscopy in spinal cord injury. Review article.

Endoscopy of the urinary tract remains the cornerstone of urological therapy. Over the years, continued refinement of the endoscopic instruments has permitted a progressive increase in the number and methods of their application. The development of the smaller diameter, flexible endoscopes represents the greatest advance in urological endoscopy. Their characteristics permit greater versatility with less traumatic procedures, increasing patient comfort and minimizing iatrogenic injury. Spinal cord injury (SCI) patients are a select group, which require special attention when undergoing endoscopic procedures. Often a contracted bladder or poorly controlled muscle spasms make the SCI patient difficult to endoscopic using conventional rigid instruments. Furthermore, autonomic dysreflexia is a significant concern during traumatic urinary tract instrumentation. This communication will discuss the applications of flexible cystoscopy, including novel techniques, which can be useful in SCI patients.

The evolution of walking-related outcomes over the first 12 weeks of rehabilitation for incomplete traumatic spinal cord injury: the multicenter randomized Spinal Cord Injury Locomotor Trial.

BACKGROUND: The Spinal Cord Injury Locomotor Trial (SCILT) compared 12 weeks of step training with body weight support on a treadmill (BWSTT) that included overground practice to a defined but more conventional overground mobility intervention (CONT) in patients with incomplete traumatic SCI within 8 weeks of onset. No previous studies have reported walking-related outcomes during rehabilitation. METHODS: This single-blinded, randomized trial entered 107 American Spinal Injury Association (ASIA) C and D patients and 38 ASIA B patients with lesions between C5 and L3 who were unable to walk on admission for rehabilitation. The Functional Independence Measure (FIM-L) for walking, 15-m walking speed, and lower extremity motor score (LEMS) were collected every 2 weeks. RESULTS: No significant differences were found at entry and during the treatment phase (12-week mean FIM-L = 5, velocity = 0.8 m/s, LEMS = 35, distance walked in 6 min = 250 m). Combining the 2 arms, a FIM-L >or= 4 was achieved in < 10% of ASIA B patients, 92% of ASIA C patients, and all of ASIA D patients. Walking speed of >or= 0.6 m/s correlated with a LEMS near 40 or higher. CONCLUSIONS: Few ASIA B and most ASIA C and D patients achieved functional walking ability by the end of 12 weeks of BWSTT and CONT, consistent with the primary outcome data at 6 months. Walking-related measures assessed at 2-week intervals reveal that time after SCI is an important variable for entering patients into a trial with mobility outcomes. By about 6 weeks after entry, most patients who will recover have improved their FIM-L to >3 and are improving in walking speed. Future trials may reduce the number needed to treat by entering patients with FIM-L < 4 at > 8 weeks after onset if still graded ASIA B and at > 12 weeks if still ASIA C.

Factors associated with risk for subsequent injuries after traumatic spinal cord injury.

OBJECTIVES: To identify the annual incidence and risk factors for subsequent injury among subjects with preexisting spinal cord injury (SCI). DESIGN: Cross-sectional, mailed survey. SETTING: A specialty hospital in the southeastern United States. PARTICIPANTS: Subjects (N=1328) with SCI participated in this study (response rate, 72%), each of whom met the following inclusion criteria: (1) traumatic SCI with residual impairment American Spinal Injury Association (ASIA) grades A through D, (2) nonsurgical onset, (3) age 18 years or older at the time of the study, and (4) a minimum of 12 months post-SCI. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: A general health assessment survey was used that required participants to report the number of injuries that were severe enough to require treatment in a clinic, emergency department, or hospital in the past year, as well as whether any injury resulted in hospitalization. Risk measures included the Behavioral Risk Factor Surveillance System, CAGE, Zuckerman-Kuhlman Personality Questionnaire, Multidimensional Health Locus of Control scale, and prescription medication usage. RESULTS: Nineteen percent of participants reported at least 1 injury within the past year, with an annual incidence of.33 when considering those with multiple injuries. Twenty-seven percent of those with at least 1 injury reported 1 or more injury-related hospitalizations in the past year. Being younger; having an ASIA grade D injury; higher sensation-seeking scores; heavy drinking; and prescription medication use for pain, spasticity, depression, and sleep were associated with a greater likelihood of subsequent injuries. CONCLUSIONS: Subsequent injuries impact nearly 20% of people with SCI annually; yet, this problem has received little attention in the literature. Further study is needed to identify the costs, severity, and circumstances surrounding injury to design prevention programs that target risk behaviors.

MRI detection of unsuspected vertebral injury in acute spinal trauma: incidence and significance.

OBJECTIVE: Multilevel spinal injury is well recognised. Previous studies reviewing the radiographs of spinal injury patients have shown an incidence of 15.2% of unsuspected spinal injury. It is recognised that magnetic resonance imaging (MRI) can identify injuries that are not demonstrated on radiographs. The objective of this study was to determine the incidence and significance of spinal injuries using MRI in comparison with radiographs. DESIGN AND PATIENTS: The radiographs and MR images of 110 acute spinal injury patients were reviewed independently of each other and the findings were then correlated to determine any unsuspected injury. RESULTS: MRI detected vertebral body bone bruises (microtrabecular bone injury) in 41.8% of spinal injury patients which were not seen on radiographs. These bone bruises were best appreciated on sagittal short tau inversion recovery MR sequences and seen at contiguous and non-contiguous levels in relation to the primary injury. CONCLUSION: This level of incidence of bone bruises has not previously been appreciated. We recommend that patients undergoing MRI for an injured segment of the spine are better assessed by MRI of the entire spine at the same time to exclude further injury.

Activated microglia contribute to the maintenance of chronic pain after spinal cord injury.

Traumatic spinal cord injury (SCI) results not only in motor impairment but also in chronic central pain, which can be refractory to conventional treatment approaches. It has been shown recently that in models of peripheral nerve injury, spinal cord microglia can become activated and contribute to development of pain. Considering their role in pain after peripheral injury, and because microglia are known to become activated after SCI, we tested the hypothesis that activated microglia contribute to chronic pain after SCI. In this study, adult male Sprague Dawley rats underwent T9 spinal cord contusion injury. Four weeks after injury, when lumbar dorsal horn multireceptive neurons became hyperresponsive and when behavioral nociceptive thresholds were decreased to both mechanical and thermal stimuli, intrathecal infusions of the microglial inhibitor minocycline were initiated. Electrophysiological experiments showed that minocycline rapidly attenuated hyperresponsiveness of lumbar dorsal horn neurons. Behavioral data showed that minocycline restored nociceptive thresholds, at which time spinal microglial cells assumed a quiescent morphological phenotype. Levels of phosphorylated-p38 were decreased in SCI animals receiving minocycline. Cessation of delivery of minocycline resulted in an immediate return of pain-related phenomena. These results suggest an important role for activated microglia in the maintenance of chronic central below-level pain after SCI and support the newly emerging role of non-neuronal immune cells as a contributing factor in post-SCI pain.

Massive steroids do not reduce the zone of injury after penetrating spinal cord injury.

The National Acute Spinal Cord Injury Study II concluded in 1990 that high-dose methylprednisolone (MP) improved neurologic recovery after acute spinal cord injury (ASCI). We tested this conclusion by analysis of 54 patients with ASCI; 25 patients were treated without MP before 1990 whereas 29 patients were treated with MP after 1990. Neurologic deficit was assessed regularly, in most cases daily. Motor and sensory scores on admission, and best results at one-half week (days 2 to 4), 1 week (days 6 to 10), 2 weeks (days 11 to 21), 1 month, and 2 months were noted for both groups. Motor assessment was recorded in 22 muscle segments on a scale of 0 (complete deficit) to 5 (normal); the range, thus, was 0 to 110. The 23 patients with closed injuries demonstrated no difference in improvement with or without MP. In contrast, MP was associated with impaired improvement in the patients with penetrating wounds; the 15 patients with no MP therapy had an admission motor score of 49, which increased by 6.9 at one-half week, whereas the 16 patients treated with MP had an admission motor score of 48, which decreased by 0.3 at one-half week (p = 0.03). The neural status seen by day 4 persisted throughout the next 2 months. Changes in sensation paralleled the changes in motor function. We conclude that MP therapy for penetrating ASCI may impair recovery of neurologic function.

Further characterization of the external urethral sphincter in spinal cord injury: study during spinal shock and evolution of responsiveness to alpha-adrenergic stimulation.

To shed further insight into its ever evolving concepts, we studied the activity of the external urethral sphincter in patients with spinal cord injury. Study during the phase of acute spinal shock revealed persistent electromyographic activity in the external urethral sphincter and no activity in the external anal sphincter, suggesting the presence of functional dissociation between the 2 sphincters from the onset of acute spinal injury. The genesis of dissociated activity was discussed by reference to recent experiments on the individual differences in motor neuron and muscle subtypes. Only the external urethral sphincter of chronic paraplegics demonstrated a uniformly increased electromyographic activity after alpha-adrenergic stimulation, while the response in the external anal sphincter was variable. The mechanism of increased response to alpha-adrenergic stimulation in the denervated external urethral sphincter appears to reside either in direct postsynaptic stimulation or recruitment of motor neurons other than the somatic pudendal system, since pre-treatment with competitive muscle relaxant failed to block this increased response in the external urethral sphincter.

Do spinal cord injury patients always get the best treatment for neuropathic bladder after discharge from regional spinal injuries centre?

OBJECTIVE: To draw attention to inadequate care received by some spinal cord injury patients after discharge from the regional spinal injury center. SETTING: Regional Spinal Injuries Centre, Southport, UK. METHODS: Presence of the urethral stricture was not recognised in a 69-year-old male with T-3 paraplegia, who attended a health-care facility with a urinary infection. A Foley catheter was inserted into the urethra only half-way and the catheter balloon was then inflated in the urethra distal to the stricture. In a 68-year-old male with T-8 paraplegia, a long-term indwelling catheter was eroding the urethra and he developed a severe degree of hypospadias while being managed in the community. A 49-year-old male with C-4 tetraplegia developed recurrent urine infections. He received several courses of antibiotics, which were prescribed by community health professionals. But he continued to be unwell. Subsequently, the patient was admitted to a district general hospital, where he was diagnosed to have mild chest infection and was about to be sent home. However, his wife was not happy, and then ultrasound of abdomen was taken, which revealed pyonephrosis. He was then transferred to a spinal unit. RESULTS: : These patients were not seen promptly in a regional spinal injury centre when they developed medical problems. The complications, which ensued, might have been prevented if expert medical treatment had been provided without delay. CONCLUSION: In order to meet the needs of a growing population of persons living in the community with spinal cord injury, more beds are required in spinal units. Provision of day surgery wards within spinal units, out-reach clinics and home visits by spinal cord clinicians may reduce the demand for admission in a spinal unit. Education of community health professionals on delayed complications of spinal cord injury, and good communication between spinal cord clinicians, patients, carers, and community health professionals by telephone, e-mail or conventional postal system are likely to improve the care of spinal cord injury patients after discharge from spinal injury centres. Spinal cord clinicians should adopt a patient-centred care instead of the traditional, paternalistic, doctor-centred care.

Issues in surgical treatment of thoraco-lumbar injuries associated with spinal cord injuries in children and adolescents.

To evaluate standards of care in surgical treatment of thoracolumbar injuries (TLIs), we reviewed the cases of 79 surgically treated patients (39 males, 36 females) with TLIs and spinal cord injuries occurring from January 1985 to January 2000. We assessed radiographs of fracture-dislocation reductions; restorations of sagittal and coronal alignment of injured segments; instrumentation levels and strategies; operations, and reoperations. Mean age at time o f injury was 14.1 years. The majority of injuries were thoracic, and posterior spinal fusion with instrumentation was the most common index procedure performed. Mean follow-up was 23.4months. Reoperation rate was 20%. Problems in achieving fracture reduction, selecting correct instrumentation levels, restoring proper sagittal alignment, an d planning a nd performing surgeries were more prevalent in patients treated before 1990 but are still problematic, even with use of modern segmental instrumentation, and frequently require revision to improve function or relieve symptoms. These results indicate a wide range in standards of care in surgical treatment of TLIs.

Cervical spinal cord injury without bony injury.

Cervical spinal cord injury without demonstrable bony injury occurred in 141 (37%) of 384 successive neck injuries admitted to the Sheffield Spinal Injuries Unit. The condition was common in patients in the older age-groups and there were 70% of the cases who were over the age of 50 years. The commonest cause was a fall. The patients presented with varying degrees of motor paralysis with the greatest deficits in the upper limbs and lesser deficits in the lower limbs. There was a dissociation of impairment of the sensory modalities and a loss of bladder and bowel control.

Effects of the Second National Acute Spinal Cord Injury Study of high-dose methylprednisolone therapy on acute cervical spinal cord injury-results in spinal injuries center.

STUDY DESIGN: Retrospective single-center study. OBJECTIVE: To evaluate the recovery of motor function and the early complications in patients with acute cervical spinal cord injury after receiving a high dose of methylprednisolone sodium succinate (MPSS) within 8 hours of injury. SUMMARY OF BACKGROUND DATA: High-dose MPSS therapy has been demonstrated to improve the neurologic recovery in patients with acute spinal cord injury. However, it remains a controversial treatment. METHODS: Seventy patients were included in this study: 37 in the MPSS group who were treated with MPSS within 8 hours of their injury according to the Second National Acute Spinal Cord Injury Study protocol, and 33 in non-MPSS group who were not administered with MPSS. Improvements in the American Spinal Injury Association motor score were compared between the MPSS group and the non-MPSS group. In patients with complete motor loss at admission and follow-up periods, improvements of myotomal levels between the MPSS (n = 15) and non-MPSS groups (n = 21) were compared. Early complications within 6 weeks of high-dose MPSS therapy were compared with those of no MPSS therapy. RESULTS: Among the patients with incomplete paralysis at admission, the American Spinal Injury Association motor scores in the MPSS group were improved more significantly than those in the non-MPSS group at 6 weeks and 6 months after injury. Meanwhile, among the patients with complete paralysis at admission, the patients in the MPSS group did not show significantly more change in motor score than those in the non-MPSS group. Improvement in myotomal level had no significant difference between the MPSS and non-MPSS groups. The MPSS group had 10 patients with early complications, while the non-MPSS group had 14. The differences between the 2 groups showed no statistical significance. CONCLUSIONS: MPSS should be administered to patients with incomplete cervical spinal cord injury according to the Second National Acute Spinal Cord Injury Study protocol.

Galveston Orientation and Amnesia Test: its utility in the determination of closed head injury in acute spinal cord injury patients.

The incidence of closed head injury (CHI) associated with acute spinal cord injury (SCI) has been estimated at 40% to 50%. Closed head injury can be defined as the presence of loss of consciousness (LOC) and/or posttraumatic amnesia (PTA). Consequently, one of the difficulties in establishing a diagnosis of CHI is determining the existence of PTA in those patients without documented LOC. Previous work described the inconsistent evaluation of PTA in the SCI population. This study was conducted to evaluate the utility of the Galveston Orientation and Amnesia Test (GOAT) in establishing the diagnosis of CHI in a series of acute traumatic SCI patients. The GOAT was administered serially for three to five days to 34 patients admitted to our hospital. When information derived from the GOAT was added to that derived from review of medical records alone, the observed incidence of PTA (and by implication CHI) increased significantly (McNemar statistic = 6.4; p = 0.01). The GOAT is a quick, simple, and reproducible evaluation of spheres of orientation, which is extremely helpful in diagnosis of PTA in this population. This instrument should be used to evaluate patients at high risk for head injury. Although abnormalities in the GOAT evaluation may also be attributable to factors other than CHI (eg, hypoxia, medication effects), such findings provide evidence suggestive of CHI. This will help determine which patients require a more detailed neuropsychologic assessment.

Molecular targets in spinal cord injury.

The spinal cord can be compared to a highway connecting the brain with the different body levels lying underneath, with the axons being the ultimate carriers of the electrical impulse. After spinal cord injury (SCI), many cells are lost because of the injury. To reconstitute function, damaged axons from surviving neurons have to grow through the lesion site to their initial targets. However, the territory they have to traverse has changed: the highway is full of inhibitory signals (myelin and scar components); the pavement itself has become bumpy (demyelination); and specialized cells are recruited to clear the way (inflammatory cells). Thus, actual strategies to treat spinal injuries aim at providing a permissive environment for regenerating axons and boosting the endogenous potential of axons to regenerate while limiting progression of secondary damage. Here we review some of the strategies currently under consideration to treat spinal injuries.

Rehabilitation outcomes following traumatic spinal cord injury in a tertiary spinal cord injury centre: a comparison with an international standard.

STUDY DESIGN: Retrospective descriptive analysis of data of patients with traumatic spinal cord injury (SCI) in a tertiary SCI centre. OBJECTIVES: To identify the characteristics of the rehabilitation outcomes of patients with different levels of traumatic SCI and to compare the results with data reported in the American Consortium for Spinal Cord Medicine. SETTING: A newly established tertiary SCI centre in Tai Po Hospital, Tai Po, Hong Kong. METHODS: A total of 33 patients with traumatic SCI admitted in 2002 were included in the study. They were classified into different ASIA subgroups based on their levels and completeness of injury. The functional status changes measured by the Functional Independence Measure (FIM) (on admission, placement and upon discharge, and at 1 and 3 months post discharge) and discharge placement were recorded as rehabilitation outcomes. RESULTS: A total, 24 patients were tetraplegic while nine were paraplegic. Seven and two from tetraplegic and paraplegic groups were readmitted with late complications due to urinary tract infection, spasticity and/or occurrence of pressure sores. The mean age was found to be 48.36 (SD=15.64) years. In all, 16 (48.48%) sustained the injury from falling from height. The trend of FIM motor scores at discharge across different ASIA subgroups appeared to be comparable to those reported in the American Consortium for Spinal Cord Medicine with scores generally lower. Significant functional improvements during the hospital phase were found in the two tetraplegic and paraplegic ASIA D subgroups (t3=3.430, P<0.05; t2=4.083, P=0.55, respectively). Significant differences were also revealed among subgroups (F(7,32)=6.625, P<0.0005) with lower level tetraplegic groups appearing to stay much longer in the rehabilitation centre. In all, 64.5% of newly diagnosed patients returned to live in the community. CONCLUSIONS: This report gives a preliminary overview on the characteristics of rehabilitation outcomes in one of the SCI centres in Hong Kong in relation to the international standard. Longitudinal study with larger population and community integration outcomes might be included in the future to reveal a better picture in the SCI rehabilitation in Hong Kong.

Cognitive dysfunction and mild closed head injury in traumatic spinal cord injury.

Previous investigators have reported that 25%-50% of traumatic spinal cord injury (SCI) patients sustain loss of consciousness (LOC), posttraumatic amnesia (PTA), or both concurrently with their SCI. A LOC of 20 minutes or less, or a PTA of 24 hours has been associated with prolonged time off work, and deficits in attention, concentration, memory, and judgment. Consequently, many traumatic SCI patients may also be the victims of a concomitant closed head injury (CHI) with cognitive sequelae. To test this hypothesis, a prospective study was conducted of 30 consecutive trauma-related SCI patients admitted to the Rehabilitation Institute of Chicago to determine the incidence of CHI and cognitive dysfunction (CD). The Halstead Category Test (HCT) was administered to each patient between 8 and 12 weeks after injury, and was considered abnormal if the patient committed 51 or more errors. Fifty-seven percent (n = 11) of all patients had abnormal HCT scores suggestive of higher level cognitive dysfunction. Patients with a new CHI had a mean HCT score of 65.2, as compared to 63.5 for patients with a premorbid CHI, and 46.3 for patients without a history of CHI. Although there was a trend toward higher HCT scores in patients who had any history of CHI, these differences did not reach statistical significance. The results of this study suggest that many trauma-related SCI patients are at risk for CD eight weeks after injury. Such cognitive abnormalities would be expected to impede rehabilitation and retard the requisite learning of new skills.

Lithium chloride reinforces the regeneration-promoting effect of chondroitinase ABC on rubrospinal neurons after spinal cord injury.

After spinal cord injury, enzymatic digestion of chondroitin sulfate proteoglycans promotes axonal regeneration of central nervous system neurons across the lesion scar. We examined whether chondroitinase ABC (ChABC) promotes the axonal regeneration of rubrospinal tract (RST) neurons following injury to the spinal cord. The effect of a GSK-3beta inhibitor, lithium chloride (LiCl), on the regeneration of axotomized RST neurons was also assessed. Adult rats received a unilateral hemisection at the seventh cervical spinal cord segment (C7). Four weeks after different treatments, regeneration of RST axons across the lesion scar was examined by injection of Fluoro-Gold at spinal segment T2, and locomotor recovery was studied by a test of forelimb usage. Injured RST axons did not regenerate spontaneously after spinal cord injury, and intraperitoneal injection of LiCl alone did not promote the regeneration of RST axons. Administration of ChABC at the lesion site enhanced the regeneration of RST axons by 20%. Combined treatment of LiCl together with ChABC significantly increased the regeneration of RST axons to 42%. Animals receiving combined treatment used both forelimbs together more often than animals that received sham or single treatment. Immunoblotting and immunohistochemical analysis revealed that LiCl induced the expression of inactive GSK-3beta as well as the upregulation of Bcl-2 in injured RST neurons. These results indicate that in vivo, LiCl inhibits GSK-3beta and reinforces the regeneration-promoting function of ChABC through a Bcl-2-dependent mechanism. Combined use of LiCl together with ChABC could be a novel treatment for spinal cord injury.

Administration of methylprednisolone for 24 or 48 hours or tirilazad mesylate for 48 hours in the treatment of acute spinal cord injury. Results of the Third National Acute Spinal Cord Injury Randomized Controlled Trial. National Acute Spinal Cord Injury Study.

OBJECTIVE: To compare the efficacy of methylprednisolone administered for 24 hours with methyprednisolone administered for 48 hours or tirilazad mesylate administered for 48 hours in patients with acute spinal cord injury. DESIGN: Double-blind, randomized clinical trial. SETTING: Sixteen acute spinal cord injury centers in North America. PATIENTS: A total of 499 patients with acute spinal cord injury diagnosed in National Acute Spinal Cord Injury Study (NASCIS) centers within 8 hours of injury. INTERVENTION: All patients received an intravenous bolus of methylprednisolone (30 mg/kg) before randomization. Patients in the 24-hour regimen group (n=166) received a methylprednisolone infusion of 5.4 mg/kg per hour for 24 hours, those in the 48-hour regimen group (n=167) received a methylprednisolone infusion of 5.4 mg/kg per hour for 48 hours, and those in the tirilazad group (n=166) received a 2.5 mg/kg bolus infusion of tirilazad mesylate every 6 hours for 48 hours. MAIN OUTCOME MEASURES: Motor function change between initial presentation and at 6 weeks and 6 months after injury, and change in Functional Independence Measure (FIM) assessed at 6 weeks and 6 months. RESULTS: Compared with patients treated with methylprednisolone for 24 hours, those treated with methylprednisolone for 48 hours showed improved motor recovery at 6 weeks (P=.09) and 6 months (P=.07) after injury. The effect of the 48-hour methylprednisolone regimen was significant at 6 weeks (P=.04) and 6 months (P=.01) among patients whose therapy was initiated 3 to 8 hours after injury. Patients who received the 48-hour regimen and who started treatment at 3 to 8 hours were more likely to improve 1 full neurologic grade (P=.03) at 6 months, to show more improvement in 6-month FIM (P=.08), and to have more severe sepsis and severe pneumonia than patients in the 24-hour methylprednisolone group and the tirilazad group, but other complications and mortality (P=.97) were similar. Patients treated with tirilazad for 48 hours showed motor recovery rates equivalent to patients who received methylprednisolone for 24 hours. CONCLUSIONS: Patients with acute spinal cord injury who receive methylprednisolone within 3 hours of injury should be maintained on the treatment regimen for 24 hours. When methylprednisolone is initiated 3 to 8 hours after injury, patients should be maintained on steroid therapy for 48 hours.
