Randomized controlled trial of pharmacological replacement of melatonin for sleep disruption in individuals with tetraplegia

OBJECTIVE

To determine the effectiveness of a melatonin agonist for treating sleep disturbances in individuals with tetraplegia.

DESIGN

Placebo-controlled, double-blind, crossover, randomized control trial.

SETTING

At home.

PARTICIPANTS

Eight individuals with tetraplegia, having an absence of endogenous melatonin production and the presence of a sleep disorder. Interventions Three weeks of 8 mg of ramelteon (melatonin agonist) and 3 weeks of placebo (crossover, randomized order) with 2 weeks of baseline prior to and 2 weeks of washout between active conditions.

OUTCOME

Change in objective and subjective sleep.

MEASURES

Wrist actigraphy, post-sleep questionnaire, Stanford sleepiness scale, SF-36.

RESULTS

We observed no consistent changes in either subjective or objective measures of sleep, including subjective sleep latency (P = 0.55, Friedman test), number of awakenings (P = 0.17, Friedman test), subjective total sleep time (P = 0.45, Friedman test), subjective morning alertness (P = 0.35, Friedman test), objective wake after sleep onset (P = 0.70, Friedman test), or objective sleep efficiency (P = 0.78, Friedman test). There were significant increases in both objective total sleep time (P < 0.05, Friedman test), subjective time in bed (P < 0.05, Friedman test), and subjective sleep quality (P < 0.05, Friedman test), although these occurred in both arms. There were no significant changes in any of the nine SF-36 subscale scores (Friedman test, Ps >Bonferroni adjusted α of 0.005).

CONCLUSION

In this pilot study, we were unable to show effectiveness of pharmacological replacement of melatonin for the treatment of self-reported sleep problems in individuals with tetraplegia. Trial Registration ClinicalTrials.gov # NCT00507546.

Spinal cord injury community survey: a national, comprehensive study to portray the lives of canadians with spinal cord injury

BACKGROUND

To better understand service-related needs and the current situation of persons with spinal cord injury (SCI) living in the community, a more comprehensive approach for studying their interrelationships (needs vs community living outcomes) is greatly needed.

OBJECTIVE

To describe the development, design, and findings of a Canadian survey portraying the life situation of people with SCI.

METHOD

The SCI Community Survey covers demographics, health, SCI-specific needs, community participation, employment, quality of life, health care utilization, and overall health rating. A total of 1,549 persons with SCI completed the survey (Web or phone) between May 2011 and August 2012.

RESULTS

Some major expressed needs for services to support community living are met to a great extent for a substantial proportion of people with SCI. Complications remain highly prevalent for some health issues, including pain, sexual dysfunction, and musculoskeletal disorders. The extent of community participation based on values and preferences varies tremendously among daily activities and social roles. Some dimensions of quality of life are rated positively (eg, family life) while others are greatly disrupted (eg, sex life and physical health). Most of these findings vary significantly between people with traumatic and nontraumatic lesions.

CONCLUSION

This survey is the first in Canada and among the first worldwide to draw a comprehensive picture of major aspects of the lives of people with SCI including service needs. The results will help to determine the links between various aspects of community living and guide service providers and policy makers in focusing on major issues to enhance quality of life after SCI.

An Exploratory Analysis of the Potential Association Between SCI Secondary Health Conditions and Daily Activities

BACKGROUND

Secondary health conditions (SHCs) are common following traumatic spinal cord injury (tSCI) and are believed to influence a person's ability to participate in daily activities (DAs). This association should be understood so that health care providers may target interventions with clarity and purpose to manage SHCs and facilitate DAs to maximal effect.

OBJECTIVE

To explore the association between SHCs and DAs expressed as the increased chance of not participating as much as wanted in a DA when an SHC is present.

METHODS

Community-dwelling persons with tSCI (n = 1,137) responded to the SCI Community Survey. The occurrence and frequency of 21 SHCs were determined. The extent of participation in 26 DAs was measured. The relative risk (RR) of not participating as much as wanted in a DA when a SHC is present was calculated.

RESULTS

When some SHC were present, the RR of not participating as much as wanted increased significantly (range, 15%-153%; P < .001). Certain SHCs (light-headedness/dizziness, fatigue, weight problems, constipation, shoulder problems) were associated with a greater chance of not participating in many DAs. No single SHC was associated with every DA and conversely not every DA was associated with an SHC.

CONCLUSIONS

Maximizing participation in DAs requires minimizing SHCs in every instance. Understanding the association between SHCs and DAs may facilitate targeted care resulting in less severe SHCs, greater participation in DAs, and benefits to both the individual and society.

Tetraplegia is a risk factor for central sleep apnea

Sleep-disordered breathing (SDB) is highly prevalent in patients with spinal cord injury (SCI); the exact mechanism(s) or the predictors of disease are unknown. We hypothesized that patients with cervical SCI (C-SCI) are more susceptible to central apnea than patients with thoracic SCI (T-SCI) or able-bodied controls. Sixteen patients with chronic SCI, level T6 or above (8 C-SCI, 8 T-SCI; age 42.5 ± 15.5 years; body mass index 25.9 ± 4.9 kg/m(2)) and 16 matched controls were studied. The hypocapnic apneic threshold and CO2 reserve were determined using noninvasive ventilation. For participants with spontaneous central apnea, CO2 was administered until central apnea was abolished, and CO2 reserve was measured as the difference in end-tidal CO2 (PetCO2) before and after. Steady-state plant gain (PG) was calculated from PetCO2 and VE ratio during stable sleep. Controller gain (CG) was defined as the ratio of change in VE between control and hypopnea or apnea to the ΔPetCO2. Central SDB was more common in C-SCI than T-SCI (63% vs. 13%, respectively; P < 0.05). Mean CO2 reserve for all participants was narrower in C-SCI than in T-SCI or control group (-0.4 ± 2.9 vs.-2.9 ± 3.3 vs. -3.0 ± 1.2 l·min(-1)·mmHg(-1), respectively; P < 0.05). PG was higher in C-SCI than in T-SCI or control groups (10.5 ± 2.4 vs. 5.9 ± 2.4 vs. 6.3 ± 1.6 mmHg·l(-1)·min(-1), respectively; P < 0.05) and CG was not significantly different. The CO2 reserve was an independent predictor of apnea-hypopnea index. In conclusion, C-SCI had higher rates of central SDB, indicating that tetraplegia is a risk factor for central sleep apnea. Sleep-related hypoventilation may play a significant role in the mechanism of SDB in higher SCI levels.

Neuropsychological Assessment and Treatment Following a Spinal Cord Injury and Alcohol Withdrawal

Mr. Wellington, a 61-year-old veteran, was referred for a neuropsychological assessment and mental health treatment by his attending physician and psychologist following a spinal cord injury (SCI) and alcohol withdrawal. According to the referral, Mr. Wellington had been experiencing anxiety and depressive symptoms, as well as diminished cognitive functioning. These symptoms were considered to be interfering with his participation in SCI rehabilitation. Prior to the assessment, Mr. Wellington had sustained a tetraplegic injury due to a syrinx and partial L5 injury caused by an uncontrolled chronic bone infection and was receiving treatment at a Veteran’s Administration medical center. Results of the assessment, the related challenges in identifying the etiology of the patient’s diminished neurocognitive functioning, and mental health treatment are discussed.

Systematic administration of B vitamins attenuates neuropathic hyperalgesia and reduces spinal neuron injury following temporary spinal cord ischaemia in rats

BACKGROUND

B vitamins have been demonstrated to be effective in treating chronic pain due to peripheral nerve injury. We investigated whether B vitamins could alleviate neuropathic pain and reduce neuron injury following temporary ischaemia in a rat model of spinal cord ischaemia-reperfusion injury (SCII).

METHODS

SCII was produced by transiently blocking the unilateral lumbar arteries in adult male Sprague-Dawley rats. Behavioural and neurochemical signs of neuropathic pain and spinal neuron injury were analysed with and without B vitamin treatment.

RESULTS

SCII caused behavioural thermal hyperalgesia and mechanical allodynia and neurochemical alterations, including increased expression of the vanilloid receptor 1 (VR1) and induction of c-Fos, as well as activation of the astrocytes and microglial cells in the spinal cord. Repetitive systemic administration of vitamin B complex (B1/B6/B12 at 33/33/0.5 mg/kg, i.p., daily, for 7-14 consecutive days) significantly reduced thermal hyperalgesia and the increased expression of VR1 and c-Fos, as well as activation of the astrocytes and microglial cells. SCII caused a dramatic decrease of the expression of the rate-limiting enzyme glutamic acid decarboxylase-65 (GAD65), which synthesizes γ-aminobutyric acid (GABA) in the axonal terminals, and β-III-tubulin, and also caused loss of Nissl bodies in the spinal cord. These alterations were largely prevented and rescued by the B vitamin treatment.

CONCLUSIONS

These findings support the idea that the B vitamins are capable of neuroprotection and antinociception during spinal cord injury due to temporary ischaemia. Rescuing the loss of inhibitory GABAergic tone may reduce spinal central sensitization and contribute to B vitamin-induced analgesia.

The meaning of self-care in persons with cervical spinal cord injury in Japan: a qualitative study

Background

Professionals in Japan tend to regard the individual contexts of persons with spinal cord injury (SCI) as the cause of their passive participation in self-care activities or self-management. However, the meaning of self-care involves variables that interrelate with sociocultural factors. Thus, it is necessary to uncover its meaning in the perceptions of persons with cervical spinal cord injury (CSCI) in order not only to implement better rehabilitation but also to understand the sociocultural constraints that determine the injured person’s attitudes to self-care and long-term health outcomes.

Methods

Semi-structured interviews with 29 CSCI participants from fourteen municipalities of Osaka, Hyogo, and Ehime prefectures were conducted. Participants contributed diverse perspectives on rehabilitation, lay-professional and family relationships, health promotion, and body conceptions. Interviews were recorded, transcribed and analyzed using the grounded theory approach to inter-relate categories and to develop theoretical constructions.

Results

Four main themes emerged from the data: rehabilitation for independence in ADLs; detachment from the body and self; embodiment; and self-management. From the participants’ point of view, rehabilitation programs in Japan aim at improving body functions for ADL performance, but provide little health education. These rehabilitation values might hinder some participants from developing self-esteem for their bodies. Moreover, socially-shaped family caregivers’ active engagement in the participants’ self-care allowed many participants to entirely rely on them for care. Through embodiment, participants found that self-care was not merely a means of independence in ADLs but also of self-management to enhance health and well-being, requiring collaborative relationships with caregivers.

Conclusion

Personal factors such as low motivation for self-care might be in part a reflection of social expectations of dependence for persons with CSCI. However, the shift in the meaning of self-care from ADLs to self-management implies more active participation in health care needs, shaped through social exchanges. Not only personal factors but also sociocultural factors influence the injured person’s valuation of self-care. There is a need for further research to better understand sociocultural influences on illness behaviors among persons with CSCI, so that clinical and community practice can develop accordingly.

Patients' perspectives on pain

Nociceptive and neuropathic pain (NP) are common consequences following spinal cord injury (SCI), with large impact on sleep, mood, work, and quality of life. NP affects 40% to 50% of individuals with SCI and is sometimes considered the major problem following SCI. Current treatment recommendations for SCI-NP primarily focus on pharmacological strategies suggesting the use of anticonvulsant and antidepressant drugs, followed by tramadol and opioid medications. Unfortunately, these are only partly successful in relieving pain. Qualitative studies report that individuals with SCI-related long-lasting pain seek alternatives to medication due to the limited efficacy, unwanted side effects, and perceived risk of dependency. They spend time and money searching for additional treatments. Many have learned coping strategies on their own, including various forms of warmth, relaxation, massage, stretching, distraction, and physical activity. Studies indicate that many individuals with SCI are dissatisfied with their pain management and with the information given to them about their pain, and they want to know more about causes and strategies to manage pain. They express a desire to improve communication with their physicians and learn about reliable alternative sources for obtaining information about their pain and pain management. The discrepancy between treatment algorithms and patient expectations is significant. Clinicians will benefit from hearing the patient´s voice.

Auto-titrating continuous positive airway pressure treatment for obstructive sleep apnoea after acute quadriplegia (COSAQ): study protocol for a randomized controlled trial

Background

Quadriplegia is a severe, catastrophic injury that predominantly affects people early in life, resulting in lifelong physical disability. Obstructive sleep apnoea is a direct consequence of quadriplegia and is associated with neurocognitive deficits, sleepiness and reduced quality of life. The usual treatment for sleep apnoea is nasal continuous positive airway pressure (CPAP); however, this is poorly tolerated in quadriplegia. To encourage patients to use this therapy, we have to demonstrate that the benefits outweigh the inconvenience. We therefore propose a prospective, multinational randomized controlled trial of three months of CPAP for obstructive sleep apnoea after acute quadriplegia.

Methods/design

Specialist spinal cord injury centres across Australia, New Zealand, the UK and Canada will recruit medically stable individuals who have sustained a (new) traumatic quadriplegia (complete or incomplete second cervical to first thoracic level lesions). Participants will be screened for obstructive sleep apnoea using full, portable sleep studies. Those with an apnoea hypopnoea index greater than 10 per hour will proceed to an initial three-night trial of CPAP. Those who can tolerate CPAP for at least 4 hours on at least one night of the initial trial will be randomized to either usual care or a 3-month period of auto-titrating CPAP. The primary hypothesis is that nocturnal CPAP will improve neuropsychological functioning more than usual care alone. The secondary hypothesis is that the magnitude of improvement of neuropsychological function will be predicted by the severity of baseline sleepiness measures, sleep fragmentation and sleep apnoea. Neuropsychological tests and full polysomnography will be performed at baseline and 3 months with interim measures of sleepiness and symptoms of autonomic dysfunction measured weekly. Spirometry will be performed monthly. Neuropsychological tests will be administered by blinded assessors. Recruitment commenced in July 2009.

Discussion

The results of this trial will demonstrate the effect of nocturnal CPAP treatment of obstructive sleep apnoea in acute quadriplegia. If CPAP can improve neurocognitive function after injury, it is likely that rehabilitation and subsequent community participation will be substantially improved for this group of predominantly young and severely physically disabled people.

Behavioral factors related to fatigue among persons with spinal cord injury

OBJECTIVE

To examine behavioral risk factors in relation to fatigue after spinal cord injury (SCI), specifically cardiovascular-related behaviors, prescription medication use, and alcohol and cigarette use.

DESIGN

Cross-sectional.

SETTING

A medical university in the southeastern United States.

PARTICIPANTS

Adults (N=2245) at least 1 year post-SCI from a large specialty hospital in the Southeast responded to a mail-in survey.

INTERVENTION

Not applicable.

MAIN OUTCOMES MEASURE

The Modified Fatigue Impact Scale-5-item version was used to assess disabling fatigue.

RESULTS

Of participants, 8.3% had disabling fatigue, 45.3% reported fatigue rarely to never impacted their life, and 46.4% reported having some fatigue. Persons who reported having less exercise than others with a similar injury level were 2.49 times as likely to have disabling fatigue as persons who reported more exercise. Those with a fair or poor diet were also more likely to have disabling fatigue. Use of prescription medication to treat pain was associated with disabling fatigue, as was being CAGE positive. Among nonbehavioral variables, race and injury severity were significantly associated with disabling fatigue.

CONCLUSIONS

We identified several behavioral predictors of disabling fatigue, including cardiovascular risk factors, prescription medication use, and alcohol use. These factors are important because they are able to be modified and could be potential factors for prevention or intervention.

Sleep in children with cerebral palsy: a review

Children with neurodevelopmental disabilities, such as cerebral palsy, are considered to be a population at risk for the occurrence of sleep problems. Moreover, recent studies on children with cerebral palsy seem to indicate that this population is at higher risk for sleep disorders. The importance of the recognition and treatment of sleep problems in children with cerebral palsy cannot be overemphasized. It is well known that the consequences of sleep disorders in children are broad and affect both the child and family. This review article explores the types and possible risk factors associated with the development of sleep problems in children with cerebral palsy and the impact of this disorder on the child and family. In addition, a brief summary of current diagnostic and treatment modalities is provided. Finally, the characteristics, diagnostic techniques, and management of sleep-related breathing disorders in children with cerebral palsy are discussed.

Immediate effect of transcutaneous electrical nerve stimulation on spasticity in patients with spinal cord injury

Objective: To investigate the immediate effect of transcutaneous electrical nerve stimulation (TENS) on spasticity in patients with spinal cord injury.

Design: Randomized controlled trial.

Setting: Extended rehabilitation centre.

Subjects and intervention: Eighteen subjects with spinal cord injury and symptoms of spasticity over lower limbs were randomly assigned to receive either 60 minutes of active TENS (0.25 ms, 100 Hz, 15 mA) or 60 minutes of placebo non-electrically stimulated TENS over the common peroneal nerve.

Outcome measures: Composite Spasticity Score was used to assess the spasticity level of ankle plantar flexors immediately before and after TENS application. Composite Spasticity Score consisted of Achilles tendon jerks, resistance to full-range passive ankle dorsiflexion and ankle clonus. Between-group statistical differences of reduction of Composite Spasticity Score, Achilles tendon jerks, resistance to full-range passive ankle dorsiflexion and ankle clonus were calculated using the Mann—Whitney test. Within-group statistical differences of Composite Spasticity Score, Achilles tendon jerks, resistance to full-range passive ankle dorsiflexion and ankle clonus were calculated using the Wilcoxon signed ranks test.

Results: Significant reductions were shown in Composite Spasticity Score by 29.5% (p = 0.017), resistance to full-range passive ankle dorsiflexion by 31.0% (p = 0.024) and ankle clonus by 29.6% (p = 0.023) in the TENS group but these reductions were not found in the placebo TENS group. The between-group differences of both Composite Spasticity Score and resistance to full-range passive ankle dorsiflexion were significant (p = 0.027 and p = 0.024, respectively).

Conclusion: This study showed that a single session of TENS could immediately reduce spasticity.

Review paper: epidemiology of traumatic spinal cord injury: comparisons between developed and developing countries

A review of global epidemiological studies of traumatic spinal cord injury (TSCI) within 2 decades was undertaken to compare the incidence, mortality rate, patients' age, gender, causes, and severity of injury between developed countries and developing countries. The incidence rates varied greatly, and there was also a 2-fold difference between the highest mortality rate in developing countries and that in developed countries. Male sex and age from 30 to 50 years are strong risk factors in both these groups. Traffic accidents are the leading cause of injury in developed countries, whereas falls are the leading cause in developing countries. To clarify regional differences, future studies should contain long-term data about TSCI characteristics in a region-based population.

Colonoscopic lesions in patients with spinal cord injury

BACKGROUND/OBJECTIVE

In spinal cord injury (SCI), loss of central or peripheral neural control causes neurogenic bowel. Patients may not exhibit the typical signs and symptoms of gastrointestinal disease. Few studies have looked at the risk of gastrointestinal disease in this group and the indications for preventive screening. The objective of this study was to study colonoscopic lesions in patients with SCI and determine whether there are any differences in the prevalence of lesions between SCI and control patients.

DESIGN

Case control study.

METHODS

Twenty-five patients with SCI were compared with 41 control patients who received colonoscopy at the same time. Mann-Whitney test for continuous variable, and Fisher exact test for frequency variables were used.

OUTCOME MEASURES

Demographic information, duration of SCI, and colonoscopy findings were gathered.

RESULTS

Colonic lesions were observed in 52% of patients with SCI and in 41.5% of control patients. Most frequent lesions in SCI group were inflammatory bowel disease (16%) and polyp (16%), followed by proctitis (12%) and hemorrhoid (12%). In the control group, hemorrhoid (17.1%) was most common, followed by polyp (12.2%) and melanosis coli (9.8%). No significant differences were found between the 2 groups. In the SCI group, no significant differences in lesions were found among the patients with cervical, thoracic, and lumbar SCI in the SCI group. Duration of SCI did not affect the pattern of colonoscopic lesions.

CONCLUSION

Patients with SCI had the same incidence of colonscopic lesions as control patients. Inflammatory bowel disease, which is a risk factor for cancer, was the most common findings in the SCI group, although there was no significant difference from the control group. In patients with SCI, colonoscopy screening is warranted at the same frequency as for the general population.

Agricultural workers' return to work following spinal cord injury: a comparison with other industry workers

PURPOSE

To investigate the impact of spinal cord injury on employment outcomes as experienced by agricultural workers in comparison with persons employed in other industries. Because of the challenges associated with working in many of the agricultural industries, it was anticipated that agricultural workers would achieve inferior return-to-work outcomes.

METHOD

Survey of all employed persons who experienced a traumatic spinal cord injury in southeastern Australia between 1990 and 1996 (inclusive).

RESULTS

Contrary to expectation, agricultural workers had a significantly higher rate of return to work (61.7% vs. 41.1%). However, an investigation into the hours spent working and agricultural workers' satisfaction with their employment activities, indicated that most were underemployed and had the potential to achieve even better outcomes.

CONCLUSION

Results indicate that more can be done to help injured agricultural workers achieve their employment potential.

Colorectal responses to distension and feeding in patients with spinal cord injury

The role of the central nervous system in enteroenteric motor reflexes remains controversial. Our aims were as follows: 1) to evaluate colorectal, rectocolic, gastrocolonic, and gastrorectal reflex responses in patients with cervical spinal cord injury (SCI) and 2) to compare these responses with those in healthy subjects. In six patients with SCI (5 male, 42 +/- 4 yr) and six healthy control subjects (5 male, 36 +/- 5 yr), 2-min phasic distensions were performed randomly via dual-barostat balloons in the colon and rectum. Continuous colonic and rectal balloon volumes were recorded during distensions and after a 1,000-kcal liquid meal. Mean balloon volumes were recorded before, during, and after phasic distensions and over 60 min postprandially. The colorectal response was similar in control subjects and SCI patients (rectal volume reduction = 28 +/- 11% and 15 +/- 5% in SCI patients and healthy subjects, respectively); the rectocolic response was variable. The gastrocolonic response was present in all subjects (colonic volume reduction = 49 +/- 4% and 44 +/- 3% in SCI patients and healthy subjects, respectively), with a time effect in the first 30 min (P < 0.0001) and a group effect in the second 30 min (P < 0.004). The gastrorectal response was present in four SCI patients and five healthy subjects (rectal volume reduction = 38 +/- 4% and 41 +/- 3% in SCI patients and healthy subjects, respectively), with a time effect in the first 30 min (P < 0.0001) but no group effect in the second 30 min. Intact neural transmission between the spinal cord and higher centers is not essential for normal colorectal motor responses to feeding and distension; however, a degree of central nervous system and neurohormonal modulation of these responses is likely.

Cardiomyopathy presenting as severe fatigue in a person with chronic spinal cord injury

BACKGROUND/OBJECTIVE

To describe a case of fatigue associated with cardiomyopathy in a man with spinal cord injury.

STUDY DESIGN

Case report.

SUBJECT

An obese 35-year-old man with long-term ASIA A L2 paraplegia, accompanied by a 2-year history of progressive severe fatigue.

METHODS

Physical examination showed obesity, hypertension, tachycardia, and pitting edema. An echocardiogram showed a 20% ejection fraction, severe dilation, and global hypokinesis in the left ventricle and mild to moderate mitral regurgitation.

RESULTS

Symptoms improved after treatment with furosemide, warfarin, ramipril, and continuous positive airway pressure for obstructive sleep apnea.

CONCLUSION

Severe progressive fatigue in a patient with chronic SCI may signal cardiomyopathy. Diagnostic studies may be warranted in patients with progressive fatigue.

What are the risk factors of occurence and chronicity of neuropathic pain in spinal cord injury patients?

OBJECTIVE

Analyze the epidemiological data on neuropathic pain in spinal cord injury patients and determine the risk factors for its occurrence and chronicity.

METHOD

Review and analysis of the literature.

RESULTS

Epidemiological data report that 40% of spinal cord injury (SCI) patients suffer from neuropathic pain and 40% of these patients report an intense neuropathic pain. Some factors do not seem to be predictive for the onset of neuropathic pain: the level of injury, complete or incomplete injury, the existence of an initial surgery, sex. However, old age at the time of injury, bullet injury as the cause of trauma, early onset of pain in the weeks following the injury, their initial nature, intensity and continuous pain, as well as associated symptoms all appear to be negative prognostic factors.

CONCLUSION

Neuropathic pain in SCI patients is a major issue, its determining factors still need to be evaluated properly by refining the epidemiological data.

[Management of neuropathic pain after brachial plexus injury in adult patients: a report of 60 cases]

An observational study including 60 patients with brachial plexus injury was carried out in order to evaluate the rate of chronic pain, to assess the incidence of neuropathies using the questionnaire DN4 and to record the management of pain in these patients. Chronic pain of neuropathic type according to the questionnaire DN4 was found in 95% of the patients. Although 75% of these cases were treated, only 37% of the patients were satisfied. All of these 37% who were relieved of intense pain (EVA<4) or hyperalgic crisis had an appropriate treatment in the early stages. The proportion of cases considered refractory to an appropriate treatment was lower than 2%. An effort to inform the patients and the carers must be made to improve the management of these injuries. The fact that this pathology is rare must lead to a specialized opinion in order to improve pain management.

Pharmacological management of neuropathic pain following spinal cord injury

Spinal cord injury (SCI) has a number of severe and disabling consequences, including chronic pain, and around 40% of patients develop persistent neuropathic pain. Pain following SCI has a detrimental impact on the patient's quality of life and is a major specific healthcare problem in its own right. Thus far, there is no cure for the pain and oral pharmaceutical intervention is often inadequate, commonly resulting in a reduction of only 20-30% in pain intensity. Neuropathic pain sensations are characterized by spontaneous persistent pain and a range of abnormally evoked responses, e.g. allodynia (pain evoked by normally non-noxious stimuli) and hyperalgesia (an increased response to noxious stimuli). Neuropathic pain following SCI may be present at or below the level of injury. Oral pharmacological agents used in the treatment of neuropathic pain act either by depressing neuronal activity, by blocking sodium channels or inhibiting calcium channels, by increasing inhibition via GABA agonists, by serotonergic and noradrenergic reuptake inhibition, or by decreasing activation via glutamate receptor inhibition, especially by blocking the NMDA receptor. At present, only ten randomized, double-blind, controlled trials have been performed on oral drug treatment of pain after SCI, the results of most of which were negative. The studies included antidepressants (amitriptyline and trazodone), antiepileptics (gabapentin, pregabalin, lamotrigine and valproate) and mexiletine. Gabapentin, pregabalin and amitriptyline showed a significant reduction in neuropathic pain following SCI. Cannabinoids have been found to relieve other types of central pain, and serotonin noradrenaline reuptake inhibitors as well as opioids relieve peripheral neuropathic pain and may be used to treat patients with SCI pain.

Impact of associated conditions resulting from spinal cord injury on health status and quality of life in people with traumatic central cord syndrome

OBJECTIVE

To determine the effect of associated spinal cord injury (SCI) conditions on the health status and quality of life (QOL) in people with traumatic central cord syndrome.

DESIGN

Cross-sectional design.

SETTING

Community-based.

PARTICIPANTS

Subjects (N=70) with traumatic central cord syndrome who were a minimum of 2 years postinjury.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Presence of associated SCI conditions (neuropathic pain, spasticity, bowel, bladder, and/or sexual dysfunction, decreased motor function); health status (36-Item Short-Form Health Survey [SF-36], symptom satisfaction); and QOL.

RESULTS

The SF-36 physical component score (PCS) was lower in subjects who reported problems with bowel, bladder, and/or sexual function (-6.9; 95% confidence interval [CI], -11.6 to -2.2). The PCS was decreased in subjects with a lower motor score and this relationship was negatively affected by spasticity and being less educated. The SF-36 mental component score was negatively affected by neuropathic pain and a lower motor score. Neuropathic pain and a lower motor score were both associated with subjects being dissatisfied with their symptoms. Subjects who had a higher motor score were more likely to have a higher QOL (odds ratio, 1.7; 95% CI, 1.1 to 2.7).

CONCLUSIONS

The associated SCI conditions bowel, bladder, and/or sexual dysfunction, neuropathic pain, decreased motor function, and spasticity negatively affect the health status of persons with traumatic central cord syndrome. Diminished motor recovery was the only associated SCI condition to impact QOL. By developing a conceptual model and adjusting for confounders, an estimate for each associated SCI condition's effect on patient outcomes was obtained. Our results indicate the importance of treating or ameliorating associated SCI conditions in order to maximize physical and mental functioning.

Alteration in articular cartilage of rat knee joints after spinal cord injury

OBJECTIVE

Mechanical forces are crucial for the maintenance of the morphologic and functional integrity of articular cartilage. The alteration of the articular cartilage after spinal cord injury (SCI) has been described in relation to a suppression of mechanical forces, since the joint is unloaded and restricted in movement. However, the morphological and biochemical characteristics of the cartilage after SCI are still poorly understood. We identified the localization of cartilage alterations after SCI and verified the influence of mechanical forces on the articular cartilage.

METHOD

A total of 32 Wistar rats were used. Sixteen animals underwent an SCI and 16 animals served as control. The articular cartilage of the knee joint was assessed, respectively, at 4, 8, 10, and 12 weeks after intervention by histochemical, histomorphometric, immunohistochemical, and biochemical analyses.

RESULTS

Cartilage thickness of spinal cord-injured knees decreased at the tibial and posterior femoral (FP) regions and increased at the anterior femoral (FA) region. Spinal cord injuries decreased the number of chondrocytes at the anterior regions and decreased the cartilage matrix staining only at the tibial regions. Immunolabeling to collagen type II was noted comparably in the superficial layer but noted weakly from the middle to deep layer. Collagen type I existed excessively at the cartilage surface and the pericellular regions.

CONCLUSION

Cartilage alterations after SCI would not be explained by only a suppression of mechanical forces by unloading and immobilization, but there may be influences on the cartilage in addition to the change in mechanical forces.

Chapitre B - L’incontinence anale et les troubles digestifs et leurs traitements en neuro-urologie

Anal incontinence and gastrointestinal disorders are one of the major causes of impaired quality of life in patients with neurological disease. Patients are very often too embarrassed to spontaneously talk about these problems and problems of chronic constipation can lead to microbial maceration, a known risk factor for urinary tract infection. In this article, the authors review the physiology of defecation and describe the main disorders observed in the various neurological diseases and their management.

Effects of circuit resistance training on fitness attributes and upper-extremity pain in middle-aged men with paraplegia

OBJECTIVE

To examine the effects of circuit resistance exercise (CRT) training on muscle strength, endurance, anaerobic power, and shoulder pain in middle-aged men with paraplegia.

DESIGN

Repeated testing.

SETTING

Academic medical center.

PARTICIPANTS

Seven men (age range, 39-58y) with motor-complete paraplegia from T5 to T12 and confirmed shoulder pain occurring during daily activities.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Subjects underwent a 4-month CRT program using alternating resistance maneuvers and high-speed, low-resistance arm exercise. One-repetition maximal force was measured before training and monthly thereafter. Pretraining and posttraining peak oxygen uptake (Vo(2)peak) was measured by graded arm testing. Anaerobic power was measured before and after training using a 30-second Wingate Anaerobic Test. Shoulder pain was self-evaluated by an index validated for people with spinal cord injury (Wheelchair Users Shoulder Pain Index [WUSPI]).

RESULTS

Strength increases ranging from 38.6% to 59.7% were observed for all maneuvers (P range, .005-.008). Vo(2)peak increased after training by 10.4% (P=.01), and peak and average anaerobic power increased by 6% (P=.001) and 8.6% (P=.005), respectively. WUSPI scores +/- standard deviation were lowered from 31.9+/-24.8 to 5.7+/-5.9 (P=.008), with 3 of 7 subjects reporting complete resolution of shoulder pain.

CONCLUSIONS

CRT improves muscle strength, endurance, and anaerobic power of middle-aged men with paraplegia while significantly reducing their shoulder pain.

Glutamine concentration and immune response of spinal cord-injured rats

BACKGROUND/OBJECTIVES

Glutamine plays a key role in immune response. Spinal cord injury (SCI) leads to severe loss of muscle mass and to a high incidence of infections. This study investigated the acute effect of SCI (2 and 5 days) on the plasma glutamine and skeletal muscle concentrations and immune responses in rats.

METHODS

A total of 29 adult male Wistar rats were divided as follows: control (C; n = 5), sham-operated (S2; n = 5) and spinal cord-transected (T2; n = 7). They were killed on day 2 after surgery/transection (acute phase). Another set was sham-operated (S5; n = 5), spinal cord-transected (T5; n = 7), and killed at day 5 after surgery/transection (secondary phase). Blood was collected; the white portion of the epitrochlearis and gastrocnemius muscles and the red portion of soleus muscles were dissected to measure the glutamine concentration. Gut-associated lymphocytes and peritoneal macrophages were obtained for immune parameters measurements.

RESULTS

Glutamine concentration in the plasma, gastrocnemius, and soleus muscles in rats with SCI were significantly reduced but not in the epitrochlearis muscle in the acute (2 days) and secondary (5 days) phases. Phagocytic response was reduced in the acute phase but increased in the secondary phase in rats with SCI. Superoxide production, on the other hand, was significantly increased at days 2 and 5 after SCI, and CD8+ lymphocytes subset decreased significantly on days 2 and 5.

CONCLUSIONS

Our results showed reduction in plasma glutamine and skeletal muscle concentrations after spinal cord transection. They also suggest that SCI and glutamine reduction contribute to an alteration in immune competence.

Complications in patients with spinal cord injuries sustained in an earthquake in Northern Pakistan

BACKGROUND

Spinal cord injury (SCI) is a devastating trauma suffered by many of the victims of an earthquake that struck Northern Pakistan on October 8, 2005. It rendered approximately 600 patients paraplegic, which is the highest number ever reported in any disaster. This study was conducted to evaluate the risk of complications.

METHODS

The cross-sectional retrospective study covering a 2-month period was conducted on 194 patients admitted to the surgical/neurosurgical wards of Rawalpindi Medical College and allied hospitals (Holy Family Hospital, Rawalpindi General Hospital, and District Headquarter Hospital) and Melody Relief and Rehabilitation Center, Islamabad.

RESULTS

The male-to-female ratio was approximately 1:3 (n = 50 [26%] and n = 144 [74%], respectively). The majority (78% [n = 151]) were 16 to 39 years of age; 62% (n = 120) had lumbar-level injuries, 25% (n = 48) had thoracic-level injuries, 9% (n = 18) had thoracolumbar-level injuries, and a few had cervical- or sacral-level injuries. Forty-six percent (n = 90) had American Spinal Injury Association type A injuries; 4% (n = 8) were graded B, 11% (n = 21) were graded C, 9% (n = 18) were graded D, and 14% (n = 27) were graded E. Twenty percent (n = 39) developed pressure ulcers, of which 38% (n = 15) had grade 1, 36% (n = 14) had grade 2, 23% (n = 9) had grade 3, and 3% (n = 1) had grade 4. All patients developed urinary tract infections; 15% (n = 30) had bowel complaints; 2% (n = 3) developed deep-vein thrombosis (1 died of pulmonary embolism); and 0.05% (n = 1) developed wound infection.

CONCLUSION

Awareness of potential complications in patients with paraplegia is essential to care planning in the disaster setting. The priorities include skin, bowel, and bladder care and provision of prophylactic heparin. SCI post-disaster care requires comprehensive long-term planning.

Satisfaction with sexual life among persons with traumatic spinal cord injury and meningomyelocele

PURPOSE

To study satisfaction with sexual life and self-assessed sufficiency of sexual counselling in persons with traumatic spinal cord injury (SCI) and meningomyelocele (MMC).

METHOD

A postal questionnaire on aspects of health and functioning was answered by 190 persons with traumatic SCI who had been treated in the Spinal Injuries Unit in Sahlgrenska University Hospital, Göteborg, Sweden and 41 persons with MMC who were admitted to the Young Adult Teams in Göteborg, Borås and Skövde, Sweden.

RESULTS

On a numerical scale from 0 (dissatisfied) to 10 (satisfied) the median of satisfaction with sexual life was 3 for the men and 4 for the women among the persons with traumatic SCI. In the MMC group the median of satisfaction with sexual life was 5 for the men and 8 for the women. Sexual dissatisfaction increased with increasing age in both groups. Inconvenience caused by urinary and faecal incontinence, as well as neuropathic pain increased sexual dissatisfaction in the men with traumatic SCI. A total of 69% of the men with traumatic SCI and 56-59% of the participants in other subgroups reported that the sexual counselling they had received was sufficient.

CONCLUSIONS

The results corroborate findings from earlier studies that satisfaction with sexual life is rather low among persons with SCI. Especially ageing men with traumatic SCI who have sustained injury at an older age are a challenge for rehabilitation. The high satisfaction with sexual life in the women in comparison with the men with MMC is a finding not reported earlier. Our results suggest that adequate treatment of incontinence and pain might improve even sexual satisfaction. Sexual counselling should be given to all individuals with SCI and to their partners. Sexual counselling for young adults with MMC is an important part of the rehabilitation process.

Relationship between self- and clinically rated spasticity in spinal cord injury

OBJECTIVES

To assess the relation between self- and clinically rated spasticity in spinal cord injury (SCI) and to determine the extent to which symptoms like pain are included in the patients' self-rating of spasticity.

DESIGN

Part 1: an observational, prospective, cross-sectional study and part 2: an observational, prospective, longitudinal study.

SETTING

Swiss paraplegic center.

PARTICIPANTS

Forty-seven (part 1) and 8 (part 2) persons with spastic SCI (American Spinal Injury Association grade A or B).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Clinical rating of movement-provoked spasticity using the Ashworth Scale; self-rating of general and present spasticity by the subject on a 4-point spasm severity scale and by using a visual analog scale (VAS); and questionnaires asking for antispasticity medication, impact of spasticity on daily life, body segment affected by spasticity, and symptoms associated with its occurrence.

RESULTS

There was a poor correlation (rho=.36) between clinically rated (Ashworth Scale) spasticity and self-rated general spasticity and a modest correlation (rho=.70) between Ashworth Scale and self-rated present spasticity in the cross-sectional study in 47 subjects. Questionnaires showed that symptoms like pain and other sensations were associated by the patients with spasticity. There was a significant, but weak, correlation between VAS and Ashworth Scale in the longitudinal study in 3 of the 8 subjects and nonsignificant correlations in the remaining 5 subjects.

CONCLUSIONS

A single clinical assessment of spasticity is a poor indication of a patient's general spasticity. Clinical measures of muscle tone-related spasticity should be complemented by self-rating that distinguishes muscle tone-related spasticity from spasticity affecting the sensory nervous system.

Health problems of persons with spinal cord injury living in the Netherlands

PURPOSE

To investigate the prevalence of health problems among persons with spinal cord injury (SCI) living in the Netherlands, to identify the problems experienced as most important, and to analyse the experienced impact of these most important problems on daily activities and social life.

METHOD

Postal survey among all members of the Dutch Association of Patients with SCI. The questionnaire focused on 26 health problems: 13 secondary impairments, 8 problems of daily living and 5 psychosocial problems.

RESULTS

The respondents (response rate 45.5%, 454 persons) experienced an average of 8 health problems. The most frequently occurring problems regarded bladder and bowel regulation, spasms, pain, oedema and sexuality. Except for oedema, these problems were also most often cited as the most important. The most disabling condition for both daily and social activities was pain. Few significant relationships were found between the prevalence of health problems and the level, completeness and duration of the injury or gender.

CONCLUSION

Persons with SCI living in the community experience many health problems and limitations in daily activities and social life due to these problems. The occurrence of these problems does not diminish with increasing time after injury. This strongly emphasises the need for follow-up care.

Colorectal motility and defecation after spinal cord injury in humans

Following spinal cord injury, colorectal problems are a significant cause of morbidity, and chronic gastrointestinal problems remain common with increasing time after injury. Although many cord-injured patients achieve an adequate bowel frequency with drugs and manual stimulation, the risk and occurrence of fecal incontinence, difficulties with evacuation, and need for assistance remain significant problems. The underlying physiology of colorectal motility and defecation is reviewed, and consequences of spinal cord injury on defecation are reported. A discussion of present management techniques is undertaken and new directions in management and research are suggested. There is need for more intervention in regard to bowel function that could improve quality of life, but there is also a need for more research in this area.

A longitudinal evaluation of sleep and breathing in the first year after cervical spinal cord injury

OBJECTIVES

To establish the incidence of sleep disordered breathing (SDB) after acute tetraplegia and to determine the relation between the Apnea-Hypopnea Index (AHI) score and the previously postulated predictors of SDB in tetraplegia.

DESIGN

Inception cohort. We performed full polysomnography immediately after acute tetraplegia and at 2, 4, 13, 26, and 52 weeks postinjury. Spirometry, maximum inspiratory and expiratory pressures, medication usage, and neck and abdominal girth were also assessed. Preinjury SDB was estimated using the multivariate apnea prediction equation.

SETTING

Acute care, subacute care, and community.

PARTICIPANTS

Consecutive sample with acute tetraplegia. Thirty subjects (25 men) were initially included. Thirteen completed 12 months of follow-up.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

SDB (AHI score >10 events/h) and respiratory function.

RESULTS

Three subjects (10%; 95% confidence interval [CI], 2%-28%) had probable SDB before injury. In the first 48 hours after injury, no subject had SDB. At 2 weeks, 60% (95% CI, 26%-88%) had SDB; at 4 weeks, 62% (95% CI, 38%-82%); at 13 weeks, 83% (95% CI, 61%-95%); at 26 weeks, 68% (95% CI, 44%-88%); and at 52 weeks, 62% (95% CI, 32%-86%). No consistent relation was found between the previously postulated predictors and SDB.

CONCLUSIONS

SDB is highly prevalent within 4 weeks of acute tetraplegia.

A global perspective on spinal cord injury epidemiology

Spinal cord injury (SCI) is a devastating condition often affecting young and healthy individuals around the world. This debilitating condition not only creates enormous physical and emotional cost to individuals but also is a significant financial burden to society at large. This review was undertaken to understand the global impact of SCI on society. We also attempted to summarize the worldwide demographics and preventative strategies for SCI in varying economic and climatic environments and to evaluate how cultural and economic differences affect the etiology of SCI. A PUBMED database search was performed in order to identify clinical epidemiological studies of SCI within the last decade. In addition, World Bank and World Health Organization websites were used to obtain demographics, economics, and health statistics of countries of interest. A total of 20 manuscripts were selected from 17 countries. We found that SCI varies in etiology, male-to-female ratios, age distributions, and complications in different countries. Nations with similar economies tend to have similar features and incidences in all the above categories. However, diverse methods of classifying SCI were found, making comparisons difficult. Based upon these findings, it is clear that the categorization and evaluation of SCI must be standardized. The authors suggest improved methods of reporting in the areas of etiology, neurological classification, and incidence of SCI so that, in the future, more useful global comprehensive studies and comparisons can be undertaken. Unified injury prevention programs should be implemented through methods involving the Internet and international organizations, targeting the different etiologies of SCI found in different countries.

Aging with a spinal cord injury: factors associated with the need for more help with activities of daily living

OBJECTIVES

To determine (1) the frequency of the need for more help with activities of daily living (ADLs), (2) the frequency of medical complications, and (3) the association between medical, injury-related, and sociodemographic factors and the need for more help with ADLs among those aging with spinal cord injury (SCI).

DESIGN

Cross-sectional survey.

SETTING

General community, international.

PARTICIPANTS

Volunteers (N=352) with SCI for more than 20 years.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

The need for more help with ADLs.

RESULTS

The need for more help with ADLs during the last 3 years was reported by 32.1% of participants. At least 1 medical complication was reported by 85%. Constipation (47.9%), diarrhea/bowel accidents (41.8%), and pressure ulcers (38.7%) were common. Constipation, pressure ulcers, female gender, and years postinjury were associated with needing more help with ADLs. Constipation and pressure ulcers were associated with a 97% and a 76% increase, respectively, in the likelihood of needing more help with ADLs during a 3-year time period. Female gender was associated with a 96% increased odds of needing more help with ADLs. There was a 42% increased odds of needing more help with ADLs per decade after SCI.

CONCLUSIONS

People aging with SCI are vulnerable to medical complications, and additional help is required to function. Knowledge of the effect of these factors, particularly the tetrad of constipation, pressure ulcers, female gender, and number of years postinjury, should increase awareness that more help with ADLs may be needed over time.

Exacerbation of Chronic Pain following Spinal Cord Injury

Because of the high prevalence and the refractory nature of pain following spinal cord injury (SCI), it is important to increase the understanding of what factors aggravate different types of pain. This information is related to pain generating mechanisms and may thus be useful in the diagnosis and management of these difficult pain conditions. The aims of the present study were to (1) identify variables (factors) that exacerbate chronic pain associated with SCI and (2) define the relationships among these patterns of pain exacerbation, specific pain characteristics, and psychological features. A sample out of 159 (75.5%) people with SCI and chronic pain, volunteered to participate in a mail survey. Over 50% of the sample indicated that prolonged sitting, infections, fatigue, muscle spasms, cold weather, and sudden movements exacerbated their pain. A principal components analysis detected five sets of factors that were reported to magnify pain: negative mood, prolonged afferent activity (bowel, bladder, somatic), weather, voluntary physical activity, and transient somatic afferent activity. Negative mood and prolonged afferent activity were frequently and significantly associated with both pain characteristics and psychosocial issues. A multiple regression analysis revealed that a combination of decreased activity levels due to pain (t = 3.54; p < 0.001), pain located in the frontal aspects of torso (including genitals) (t = 2.29; p < 0.05), "burning" (t = 2.26; p < 0.05), or "electric" (t = 2.09; p < 0.05) pain, and a limited perception of life control (t = -2.16; p < 0.05) was significantly associated with a high extent of pain aggravation (R2 = 0.39; p < 0.000).

The analgesic effect of intravenous ketamine and lidocaine on pain after spinal cord injury

BACKGROUND

Pain following spinal cord injury (SCI) is a therapeutic challenge. Only a few treatments have been assessed in randomized, controlled trials. The primary objective of the present study was to examine the analgesic effect of ketamine and lidocaine in a group of patients with neuropathic pain below the level of spinal cord injury. We also wanted to assess sensory abnormalities to see if this could help us to identify responders and if treatments resulted in changes of sensibility.

METHODS

Ten patients with spinal cord injury and neuropathic pain below the level of injury were included. The analgesic effect of ketamine 0.4 mg kg(-1) and lidocaine 2.5 mg kg(-1) was investigated. Saline was used as placebo. The drugs were infused over 40 min. A randomized, double-blind, three-period, three-treatment, cross-over design was used. Systemic plasma concentrations of ketamine and lidocaine were assessed. Pain rating was performed using a visual analogue scale (VAS). Sensory function was assessed with a combination of traditional sensory tests and quantitative measurement of temperature thresholds.

RESULTS

Response to treatment, defined as 50% reduction in VAS-score during infusion, was recorded in 5/10 in the ketamine, 1/10 in the lidocaine and 0/10 in the placebo groups. Neither ketamine nor lidocaine changed temperature thresholds or assessments of mechanical; dynamic and static sensibility. Nor could these sensory assessments predict response to treatment in this setting. Lidocaine and particularly ketamine were associated with frequent side-effects.

CONCLUSION

Ketamine but not lidocaine showed a significant analgesic effect in patients with neuropathic pain after spinal cord injury. The pain relief was not associated with altered temperature thresholds or other changes of sensory function.

Nontraumatic spinal cord injury rehabilitation: pressure ulcer patterns, prediction, and impact11No commercial party having a direct financial interest in the results of the research supporting this article has or will confer a benefit upon the author(s) or upon any organization with which the author(s) is/are associated

OBJECTIVE

To investigate the characteristics, predictors, and consequences of pressure ulcers in patients with nontraumatic spinal cord injury (SCI).

DESIGN

Retrospective, 3-year, case series.

SETTING

Tertiary medical unit specializing in SCI rehabilitation.

PARTICIPANTS

Consecutive sample of 134 adult inpatient referrals with nontraumatic SCI. Patients requiring initial rehabilitation or readmission were included.

INTERVENTION

Chart review.

MAIN OUTCOME MEASURES

Primary outcome measures were presence of pressure ulcers on admission to rehabilitation, incidence of new pressure ulcers developing during hospitalization, and any complications attributable to pressure ulcers during inpatient rehabilitation. Secondary objectives were to examine the predictability of risk factors for pressure ulcers, to assess the usefulness of a model previously developed for predicting pressure ulcers in patients with chronic SCI, and to estimate the effect of pressure ulcers on rehabilitation of nontraumatic SCI.

RESULTS

Prevalence of pressure ulcers among admissions was 31.3% (n=42). Only 2.2% (n=3) of patients developed a new pressure ulcer after admission. The length of stay (LOS) of patients admitted with a pressure ulcer was significantly longer than that of those without a pressure ulcer (geometric mean, 62.3 d for pressure ulcer vs 28.2 d for no pressure ulcer, P=.0001). Many previously identified risk factors for pressure ulcers in SCI patients did not apply to our nontraumatic SCI patients. It is estimated that the inpatient LOS for those patients with a significant pressure ulcer was increased by 42 days.

CONCLUSIONS

Pressure ulcers are a common complication for people with nontraumatic SCI who are admitted for rehabilitation, and they have a significant impact on LOS.

Exercise Recommendations for Individuals with Spinal Cord Injury

Persons with spinal cord injury (SCI) exhibit deficits in volitional motor control and sensation that limit not only the performance of daily tasks but also the overall activity level of these persons. This population has been characterised as extremely sedentary with an increased incidence of secondary complications including diabetes mellitus, hypertension and atherogenic lipid profiles. As the daily lifestyle of the average person with SCI is without adequate stress for conditioning purposes, structured exercise activities must be added to the regular schedule if the individual is to reduce the likelihood of secondary complications and/or to enhance their physical capacity. The acute exercise responses and the capacity for exercise conditioning are directly related to the level and completeness of the spinal lesion. Appropriate exercise testing and training of persons with SCI should be based on the individual's exercise capacity as determined by accurate assessment of the spinal lesion. The standard means of classification of SCI is by application of the International Standards for Classification of Spinal Cord Injury, written by the Neurological Standards Committee of the American Spinal Injury Association. Individuals with complete spinal injuries at or above the fourth thoracic level generally exhibit dramatically diminished cardiac acceleration with maximal heart rates less than 130 beats/min. The work capacity of these persons will be limited by reductions in cardiac output and circulation to the exercising musculature. Persons with complete spinal lesions below the T(10) level will generally display injuries to the lower motor neurons within the lower extremities and, therefore, will not retain the capacity for neuromuscular activation by means of electrical stimulation. Persons with paraplegia also exhibit reduced exercise capacity and increased heart rate responses (compared with the non-disabled), which have been associated with circulatory limitations within the paralysed tissues. The recommendations for endurance and strength training in persons with SCI do not vary dramatically from the advice offered to the general population. Systems of functional electrical stimulation activate muscular contractions within the paralysed muscles of some persons with SCI. Coordinated patterns of stimulation allows purposeful exercise movements including recumbent cycling, rowing and upright ambulation. Exercise activity in persons with SCI is not without risks, with increased risks related to systemic dysfunction following the spinal injury. These individuals may exhibit an autonomic dysreflexia, significantly reduced bone density below the spinal lesion, joint contractures and/or thermal dysregulation. Persons with SCI can benefit greatly by participation in exercise activities, but those benefits can be enhanced and the relative risks may be reduced with accurate classification of the spinal injury.
