RESUMEN

This report describes a case of cauda equina syndrome possibly caused by arachnoiditis due to levobupivacaine after spinal-epidural anesthesia. A 39-yr-old woman delivered by cesarean section under a combined spinal-epidural anesthesia. After an uneventful procedure and surgery, she complained of weakness in her lower extremities, which increased in a few hours. Neurologic examination revealed severe weakness in both her lower extremities, perianal anesthesia, and absence of muscle stretch reflexes. She was unable to urinate. Magnetic resonance imaging performed immediately revealed entirely normal results; however, gadolinium-enhanced magnetic resonance imaging 10 days later revealed contrast enhancement in the cauda equina fibers concordant with arachnoiditis. The patient was included in an intense rehabilitation program with a diagnosis of cauda equina syndrome and recovered completely in 8 wks. Practitioners should be aware of neurologic complications of spinal-epidural anesthesia. Early detection and treatment of the complication are important to minimize the risk of adverse outcome.

RESUMEN

UNLABELLED: The problems at the level of intervertebral discs are producing dysfunctions and important functional regression at the level of lumbar column, at a stage at which the patient could remain blocked in an anterior or lateral flexion position or producing an antalgic position of scoliosis that could incapacitate the patient to perform activities of daily living. The medical rehabilitation, in such cases, must seek not only the relief of local pain through different methods of obtaining it, but also the functional reeducation of the intervertebral articulations through specific analytical mobilization in order to achieve the biomechanical harmonization of the rachis. MATERIAL AND METHODS: We report the case study of a 66 year-old patient who presented to our clinic for medical consult and physical therapy when he was diagnosed with discharthrosis, hyperalgic lumbar multileveled radiculopathy at L4-L5 and L5-S1. The lumbar x-ray showed osteophytes, disc narrowing at the level of L5-S1 and inter-apophysis arthrosis. The clinical examination revealed difficulty walking with pain in the right sacroiliac articulations and right sciatic emergence with plantar paraesthesia. The patient developed pain induced scoliosis on the right side that restricted the lumbar range of motion and prevented the right flexion blocking him into an left flexion, any attempt of straightening inducing pain. The condition was treated using specific analytical lumbar mobilization for the realignment of the vertebrae complex. CONCLUSIONS: In this case study, we found that functional reeducation in cases of pain induced deviations of the rachis of the column should be centered on the harmonization of inadequate pressure and position of the complex intervertebral articulations.

RESUMEN

Innovative technological advancements in the field of orthotics, such as portable powered orthotic systems, could create new treatment modalities to improve the functional out come of rehabilitation. In this article, we present a novel portable powered ankle-foot orthosis (PPAFO) to provide untethered assistance during gait. The PPAFO provides both plantar flexor and dorsiflexor torque assistance by way of a bidirectional pneumatic rotary actuator. The system uses a portable pneumatic power source (compressed carbon dioxide bottle) and embedded electronics to control the actuation of the foot. We collected pilot experimental data from one impaired and three nondisabled subjects to demonstrate design functionality. The impaired subject had bilateral impairment of the lower legs due to cauda equina syndrome. We found that data from nondisabled walkers demonstrated the PPAFO's capability to provide correctly timed plantar flexor and dorsiflexor assistance during gait. Reduced activation of the tibialis anterior during stance and swing was also seen during assisted nondisabled walking trials. An increase in the vertical ground reaction force during the second half of stance was present during assisted trials for the impaired subject. Data from nondisabled walkers demonstrated functionality, and data from an impaired walker demonstrated the ability to provide functional plantar flexor assistance.

RESUMEN

BACKGROUND: Rapid rate magnetic stimulation of human sacral nerve roots can reduce stress incontinence. OBJECTIVE: To test stimulation for urgency incontinence due to lumbosacral plexopathy. METHODS: The authors studied patients with intractable neurogenic urinary dysfunction due to lumbosacral nerve injuries. Eligible patients were randomized to receive either real or sham repetitive lumbosacral magnetic stimulation (rLMS; 15 Hz with a total of 1500 pulses/session) for 10 sessions. Evaluation was performed before starting treatment, immediately after the 5th and 10th treatment session, and 1 month later, using rating scales to score urinary dysfunction and a visual analogue scale (VAS) to assess lower back pain. Posterior tibial nerve F-wave and H-reflexes were tested before and after treatment. RESULTS: Both treatment and control groups were comparable for baseline characters and sphincteric disturbances. The mean number of voids and incontinence per 24 hours was significantly reduced in patients who received rLMS. The improvement was maintained 1 month after the end of treatment. Patients receiving real-rLMS also reported an improvement in VAS ratings. Improvement in F-wave and H-reflex latencies after real stimulation (P = .002 and P = .036, respectively) was found as well. CONCLUSION: rLMS at 15 Hz may improve urinary dysfunction secondary to lumbosacral nerve injury. Further trials can determine the profile of patients who may benefit and optimal stimulation parameters.

RESUMEN

BACKGROUND: Red flags are recognised as indicators of possible serious spinal pathology, and their use is indicated by numerous guidelines. Similar to other countries worldwide, Scotland lacked a national view about the overall quality of the physiotherapy management of low back pain and the use of red flags. Anecdotal evidence suggested that practice varied considerably. AIM: To improve the use and documentation of red flags by physiotherapists during the assessment and management of low back pain. DESIGN: Prospective, multicentred, national data collection and improvement initiative. SETTING: National Health Service (NHS) health boards in Scotland (n=14) plus two private provider sites. PARTICIPANTS: One hundred and eighty-six individual NHS provider sites and two private provider sites, with in excess of 360 physiotherapists providing services to low back pain patients. METHOD: Measurement of documented practice in line with evidence- and consensus-based recommendations from guidelines collected via a web-based tool over two 5-week audit cycles interspersed with an improvement phase over 1 year (2008-2009). RESULTS: Data from 2147 patients showed improvement in the documentation of all red flags assessed from 33% (n=709) to 65% (n=1396), and improvement in the documentation of cauda equina syndrome from 60% (n=1288) to 84% (n=1804) over the two cycles. Only two regions provided evidence of 100% documentation of all components of cauda equina syndrome, with wide variation across the country. CONCLUSION: This national initiative resulted in considerable improvement in the documentation of red flags. Despite this, however, one in five patients did not receive optimal management as recommended by guidance. This has significant implications for patient safety and highlights the need for ongoing education of physiotherapists in this area.

RESUMEN

INTRODUCTION: Traumatic cauda equina syndromes due to projectile wounds often have a poor prognosis. We report on an unusual ballistic cauda equina traumatism with a good functional outcome. CLINICAL CASE: A 44-year-old man was admitted to emergency room for an incomplete cauda equina syndrome after trying to kill himself by means of a pneumatic nail gun. The nail had gone right through the third lumbar vertebra. Because of the stability of the fracture, orthopaedic surgery was not indicated. Neurological recovery was progressive. At 6 months, there was still a partial L5-S1 motor deficit on the left side but the patient could walk without crutches, and within an unlimited walking distance. DISCUSSION: Initial imaging displayed a projectile trajectory focused on the spinal canal on level L3, which could have been considered as bad prognosis. The positive analytic and functional outcome correlates with the limited neurological tissue damage, probably explained by the ballistic properties of the projectile. CONCLUSION: Apart from the influence of a possible surgical act, the neurological and functional prognosis of a traumatic cauda equina syndrome caused by a projectile also depends on its physical characteristics.

RESUMEN

BACKGROUND/OBJECTIVE: To examine and compare demographics and functional outcomes for individuals with spinal cord injury (SCI) clinical syndromes, including central cord (CCS), Brown-Sequard (BSS), anterior cord (ACS), posterior cord (PCS), cauda equina (CES), and conus medullaris (CMS). DESIGN: Retrospective review. SETTING: Tertiary care, level 1 trauma center inpatient rehabilitation unit. PARTICIPANTS: Eight hundred thirty-nine consecutive admissions with acute SCIs. MAIN OUTCOMES MEASURES: Functional independence measure (FIM), FIM subgroups (motor, self-care, sphincter control), length of stay (LOS), and discharge disposition. RESULTS: One hundred seventy-five patients (20.9%) were diagnosed with SCI clinical syndromes. CCS was the most common (44.0%), followed by CES (25.1%) and BSS (17.1%). Significant differences (P < or = 0.01) were found between groups with regard to age, race, etiology, total admission FIM, motor admission FIM, self-care admission and discharge FIM, and LOS. Statistical analysis between tetraplegic BSS and CCS revealed significant differences (P < or = 0.01) with respect to age (39.7 vs 53.2 years) and a trend toward significance (P < or = 0.05) with regard to self-care admission and discharge FIM. No significant differences (P < or = 0.01) were found when comparing CMS to CES. CONCLUSIONS: SCI clinical syndromes represent a significant proportion of admissions to acute SCI rehabilitation, with CCS presenting most commonly and representing the oldest age group with the lowest admission functional level of all SCI clinical syndromes. Patients with cervical BSS seem to achieve higher functional improvement by discharge compared with patients with CCS. Patients with CMS and CES exhibit similar functional outcomes. Patients with ACS and PCS show functional gains with inpatient rehabilitation, with patients with ACS displaying the longest LOS of the SCI clinical syndromes. These findings have important implications for the overall management and outcome of patients with SCI.

RESUMEN

STUDY DESIGN: A prospective study. OBJECTIVES: To identify outcomes of aged patients with lumbar spinal stenosis (LSS) treated conservatively and to examine factors that control the prognosis. SUMMARY AND BACKGROUND DATA: There have been no reports evaluating the outcomes of conservative treatments for elderly LSS patients. METHODS: A total of 89 patients, 70 years of age and older, who underwent in-hospital conservative treatment were included. The Japanese Orthopedic Association's score (JOA score) and the disturbance level of activities of daily living (ADL) were used for evaluation. Nerve involvement was classified into radicular, cauda equina, and mixed type. Myelographic findings were classified into central defect with or without block and root defect. Associations between disturbance level of ADL, nerve involvement, and myelographic classifications were investigated. RESULTS: The mean JOA score increased from 11.1 points at admission to 15.9 points at discharge, with 14.3 points maintained at the follow-up; 48.8% of radicular type showed no obstacle in ADL at the follow-up compared with 33.3% of the other types; 13.3% of central defect with block showed no obstacle in ADL compared with 47.8% of the other types with significant difference. CONCLUSION: The prognosis of conservative treatment for aged LSS was relatively good. Radicular type may be a candidate for conservative treatment. However, patients with complete block in the myelogram may not respond favorably to conservative treatment.

RESUMEN

PURPOSE: To evaluate outcome measures and the factors affecting them in patients treated between 1962 and 2000 at Loewenstein Rehabilitation Hospital, Israel. METHOD: This retrospective cohort study included 262 patients with spinal neurological lesions (spinal cord or cauda equina lesions) following degenerative spinal stenosis. Data were collected retrospectively. Survival was assessed using the Kaplan-Meier method and the relative mortality risk by the Cox model. Neurological recovery was evaluated by the change in Frankel grades, and factors that affect it were assessed by logistic regression. Associations of length of stay in rehabilitation were analyzed with ANOVA. RESULTS: Median age at lesion onset was 61 years and median survival 17.6 years. Age at spinal neurological lesion onset was found to be the only factor with a significant effect on survival. Of the 148 patients who had Frankel grades A, B, or C on admission, 58% achieved recovery to grades D and E. Frankel grade at admission, age, and spinal neurological level had a significant effect on recovery. The mean length of stay was 99.7 days, and only Frankel grade had a significant effect on length of stay. CONCLUSIONS: Patients with spinal stenosis and disabling spinal neurological lesions can achieve significant neurological recovery and survive for many years. They require adequate care in a specialist rehabilitation system.

RESUMEN

To obtain easier access to avulsed roots in the intradural space for patients suffering cervical root avulsion, the authors of this study developed a novel repair method. This involves using nerve grafts to bridge corresponding segments of the spinal cord and the trunk or cord level of the plexus, respectively, in two surgical stages. All eight patients admitted to this study received pre- and post-operative workups of electrophysiological evaluations and muscle power grading through Medical Research Council (MRC) scores. The degrees of impairment were also graded according to a modified version of Dumitru's and Wilbourn's scale (mild = 1; moderate = 2; severe = 3). The preoperative versus post-operative differences in the severity of the injuries and in the grading of the target muscle power were calculated according to the Wilcoxon signed-rank test. The preoperative degree of the severity of the injuries, as measured by electromyography (EMG), was 3.00 +/- 0.00 (mean +/- S.D.). The post-operative result was 2.125 +/- 0.641. Significant change took place after repair (P = 0.0313). Moreover, although little improvement was observed in the triceps, brachioradialis (BR), extensor carpi radialis (ECR), flexor digitorum profundus (FDP) and intrinsic hand muscles, the MRC grading showed significant yet not prominent motor recovery in the deltoid and biceps brachii (both P = 0.0313). We were impressed that the initial significant statistical results of differences in pre- and post-operative severity of the injuries and muscle power grading, demonstrated that regeneration does occur with this repair strategy.

RESUMEN

STUDY DESIGN: A case of a patient with anterior sacral meningocele that was misdiagnosed as perianal abscess is presented. After the transrectal aspiration, the patient developed meningitis and cauda equina syndrome. OBJECTIVE: To report a rare case of anterior sacral meningocele in which primary presentation was mimicking perianal abscess. SUMMARY AND BACKGROUND DATA: Anterior sacral meningocele is a rare example of spinal dysraphism. It is created by a herniation of a dural sac through a defect in the sacral wall. It is usually asymptomatic until later decades. Most of the presenting symptoms are related to the pelvic organs. In the management of anterior sacral meningocele, surgical treatment is necessary. METHODS: The reported case is that of a 35-year-old female with cauda equina syndrome due to bacterial meningitis of the anterior sacral meningocele. At the beginning, she presented signs and symptoms resembling perianal abscess. She was misdiagnosed as anorectal abscess according to the computed tomography findings. The patient then underwent transrectal aspiration. Following the aspiration, meningitis and cauda equina syndrome were developed. Meningitis was treated with the appropriate antibiotics, and the patient underwent rehabilitation for paraplegia and bladder and bowel incontinence. RESULTS: Following the rehabilitation program, the patient has recovered completely within 8 months. CONCLUSION: This case represents a rare example of anterior sacral meningocele in which the patient was misdiagnosed as perianal abscess. Meningitis either iatrogenic or spontaneous may occur during the course of anterior sacral meningocele. Once it has occurred, it may result in severe morbidity and mortality. However, our case had been treated effectively, and she had regained her health with rehabilitation program.

RESUMEN

We report the first case of diffuse abnormal insertional activity with bulbar muscle involvement. Electromyography performed 5 months earlier reported multilevel radiculopathy. A repeat electromyography study revealed short trains of positive waves without fibrillation potentials, diffusely present in all tested muscles. Positive waves were also found in the bulbar innervated muscles; these included the trapezius, frontalis, and the orbicularis oculi. This entity is important to recognize because confusion with neuromuscular syndromes can occur.

RESUMEN

OBJECTIVES: To examine the influence of the involvement of financial compensation on the results of physiotherapeutic McKenzie treatment on cervicobrachial pain. METHODS: A prospective study was carried out with a cohort of 60 patients referred to two spine clinics after they had experienced at least 5 weeks of neck pain radiating to the arm. Follow-up was performed 1 yr later using a validated questionnaire to measure the outcomes of neck and arm pain, disability, the use of analgesics and the perceived effect of the treatment as reported by the patient. RESULTS: At follow-up, there was no improvement in the group of patients for whom financial compensation was involved, whereas the group for whom compensation was involved showed highly significant improvement. CONCLUSIONS: Despite uniform selection criteria and similarity of complaints and treatment protocols, the involvement of financial compensation seemed to be associated with an adverse effect on treatment results for patients with cervicobrachial pain who were treated conservatively.

RESUMEN

Herpes zoster infection, resulting from reactivation of the dormant varicella zoster virus in the dorsal root ganglia, usually causes a painful dermatomal vesicular rash. Rarely, associated peripheral motor weakness is present, the mechanism of which is unclear. Three patients are reported who had focal limb muscle weakness associated with zoster infection. Physical and occupational therapy played a key role in motor function recovery of the patients, yet emphasis on the rehabilitation of postherpetic motor weakness is lacking in the literature. Physiatrists evaluating patients with limb muscle weakness following herpes zoster infection should be alert to this condition. The clinical syndrome of herpes zoster radiculopathy and the rehabilitation of these patients are discussed.

RESUMEN

This paper describes a semiautomated, motorized skateboard and skate system for use in progressive resistive arm exercises. This experimental system has been evaluated in an occupational therapy clinic for the past two years and found to be valuable in the treatment of impaired upper extremity function. It is superior in function and design to the previously used apparatus and provides the following features: adjustable load (force), adjustable range of motion limits, an automatic method of counting the correct repetitions of the prescribed exercise, the visual feedback to patients regarding their performance. Based on therapists' evaluations, the system's three main advantages are: a decrease in the amount of therapist/attendant time needed for the exercise program, improved performances by the patients, and a better, quantitative measure of the patients' progress.
