Rehabilitation of persons with central nervous system tumors.

A tumor that affects the central nervous system can have a dramatic impact on the individual affected, as well as his or her family and friends. The tumor, regardless of extent or location, may affect the physical, social, vocational, and emotional capabilities of the individual. Basic aspects of rehabilitation for patients with tumors affecting the brain and spinal cord are reviewed in this article. The authors have found that the same principles of neurorehabilitation applied to persons with traumatic brain injury, stroke, and traumatic spinal cord injury are equally appropriate for persons with brain and spinal cord tumors. These principles include the prevention of medical complications; the treatment of medical problems such as pain, spasticity, and neuropathic bowel and bladder; and the improvement of patients' mobility and activities of daily living. Rehabilitation specialists can help prevent complications, maximize function, and improve the quality of life for patients with central nervous system tumors.

Electrodiagnostic changes of the lower limbs in subjects with chronic complete cervical spinal cord injury.

OBJECTIVE: To assess the electrodiagnostic changes in the lower limbs as measured by nerve conduction studies (NCSs) and electromyography in individuals with chronic complete tetraplegia. DESIGN: Prospective testing of NCS and electromyography. SETTING: Model spinal cord injury rehabilitation center. PARTICIPANTS: Twenty-five individuals with chronic complete tetraplegia without risk factors for peripheral neuropathy or other lower motoneuron disorders. INTERVENTIONS: Nerve conduction parameters recorded from the peroneal, tibial, and sural nerves, and compared with normal values. The presence of spontaneous activity (SA), including fibrillation and positive sharp waves, recorded in 5 muscle groups-2 proximal (vastus medialis, iliopsoas), 2 distal (tibialis anterior, medial gastrocnemius), and L4 lumbar paraspinals. Analysis to see if the presence of SA correlated with the distance of the muscle from the spinal cord or with spasticity (measured by the modified Ashworth scale). MAIN OUTCOME MEASURES: Nerve conduction latencies and velocities; motor and sensory conduction latencies; compound muscle action potential (CMAP) and sensory nerve action potential amplitudes; spontaneous potentials: fibrillation and positive sharp waves; and spasticity. RESULTS: NCS responses were obtained at a decreased frequency relative to able-bodied subjects. Statistically significant results in comparison to normal means included a diminished sural amplitude, and diminished peroneal and tibial CMAP and nerve conduction velocity (p <.0001). SA was recorded in at least 1 of the muscles tested in 92% of subjects, with 72% having SA in more than 1 of the muscles tested affected. A significant difference was seen for SA in the medial gastrocnemius as compared with the iliopsoas (p =.039). No correlation was noted in terms of SA with degree of spasticity. CONCLUSION: A statistically significant difference in NCS responses in the lower limbs in chronic tetraplegia was found relative to normal control values. However, only the frequency of responses elicited and the decreased CMAP of the peroneal nerve are clinically significant. SA was present in many of the lower extremity muscles in the subjects. Predominantly axonal changes were evident in individuals with chronic complete tetraplegia.

Is acupuncture effective in treating chronic pain after spinal cord injury?

OBJECTIVES: To evaluate the efficacy of acupuncture as a treatment for chronic pain and secondary symptoms after spinal cord injury (SCI) and to identify disease-specific variables associated with response to treatment. DESIGN: A within-subjects design consisting of a 7(1/2)-week no-acupuncture baseline period followed by a 7(1/2)-week treatment period and a follow-up assessment 3 months posttreatment. SETTING: Medical rehabilitation research center. PARTICIPANTS: Twenty-two people with SCI who experienced moderate to severe pain of at least 6 months' duration. INTERVENTION: A course of 15 acupuncture treatments was administered over a 7(1/2)-week period. MAIN OUTCOME MEASURES: Numeric Rating Scale of pain intensity; ratings of interference with activity, individualized symptom rating, Center for Epidemiologic Studies-Depression Scale; Speilberger State Trait Anxiety Inventory, and General Well-Being Schedule. RESULTS: Ten patients (46%) showed improvement in pain intensity and pain sequelae after treatment. However, 6 patients (27%) reported an increase in pain that was still present 3 months after treatment. CONCLUSIONS: About 50% of the study sample reported substantial pain relief after acupuncture treatment, suggesting that acupuncture may provide pain relief for at least a subgroup of individuals with SCI. Future research is needed to determine what part of this effect is because of acupuncture versus nonspecific effects such as placebo effects and regression to the mean.

Effects of the routine change of chronic indwelling Foley catheters in persons with spinal cord injury.

OBJECTIVE: To determine whether routine catheter changes have any effect on the urinary white blood cell count (WBC) and bacterial culture in asymptomatic individuals with spinal cord injury (SCI) who have indwelling Foley catheters. DESIGN: Prospective case series. SETTING: Urology and SCI outpatient departments of a rehabilitation center. SUBJECTS: Twelve asymptomatic individuals (male and female) with SCI who have chronic indwelling urethral Foley catheters that are changed routinely every month. MAIN OUTCOME MEASURES: Two sets of urinalysis and urinary culture and sensitivity from each individual, one set taken through the Foley catheter before the catheter change and another set after the catheter change. WBC, bacterial identity, and colony count were measured, and the corresponding data were compared. RESULTS: All subjects had pyuria and bacteriuria before and after the catheter change. Analysis of the data showed a statistically significant increase in WBC in the urine after the indwelling Foley catheter was changed (P = .0039). However, bacterial types and corresponding colony counts remained almost completely unchanged. CONCLUSIONS: Routine change of chronic indwelling Foley catheters in asymptomatic individuals with SCI causes a significant rise in the urinary WBC, without altering the bacterial identity or colony count. Pyuria and bacteriuria are prevalent among individuals with SCI (including those who are asymptomatic) with indwelling Foley catheters. This study suggests that urinalysis should be taken before a catheter change.

Measuring professionalism in a physiatry residency training program.

A 12-item questionnaire modeled after the one prepared by the American Board of Internal Medicine dealing with professionalism was distributed to 122 physiatry residents representing six training programs, of whom 59% (72) responded. The mean item score on the survey was 7.7 (SD = 1.0) on a scale from 1 to 10, where 10 represents the highest level of professionalism. The internal reliability of the questionnaire was found to be satisfactory (Cronbach's alpha = 0.75). A factor analysis of the questionnaire items resulted in three factors explaining 64% of the variance. These factors were: excellence, honor/integrity, and altruism/respect; Eigen values were 3.35, 2.37, and 1.31, respectively. These factors are similar to those obtained in the American Board of Internal Medicine survey. This similarity is a positive feature in ongoing efforts to develop a reliable tool for measuring professionalism in physiatry residency training.

Organizational strategy influence on visual memory performance after stroke: cortical/subcortical and left/right hemisphere contrasts.

OBJECTIVE: To examine how organizational strategy at encoding influences visual memory performance in stroke patients. DESIGN: Case control study. SETTING: Postacute rehabilitation hospital. PARTICIPANTS: Stroke patients with right hemisphere damage (n = 20) versus left hemisphere damage (n = 15), and stroke patients with cortical damage (n = 11) versus subcortical damage (n = 19). MAIN OUTCOME MEASURES: Organizational strategy scores, recall performance on the Rey-Osterrieth Complex Figure (ROCF). RESULTS: Results demonstrated significantly greater organizational impairment and less accurate copy performance (i.e., encoding of visuospatial information on the ROCF) in the right compared to the left hemisphere group, and in the cortical relative to the subcortical group. Organizational strategy and copy accuracy scores were significantly related to each other. The absolute amount of immediate and delayed recall was significantly associated with poor organizational strategy scores. However, relative to the amount of visual information originally encoded, memory performances did not differ between groups. CONCLUSIONS: These findings suggest that visual memory impairments after stroke may be caused by a lack of organizational strategy affecting information encoding, rather than an impairment in memory storage or retrieval.

High-dose methylprednisolone may do more harm for spinal cord injury.

Because of the National Acute Spinal Cord Injury Studies (NASCIS), high-dose methylprednisolone became the standard of care for the acute spinal cord injury. In the NASCIS, there was no mention regarding the possibility of acute corticosteroid myopathy that high-dose methylprednisolone may cause. The dosage of methylprednisolone recommended by the NASCIS 3 is the highest dose of steroids ever being used during a 2-day period for any clinical condition. We hypothesize that it may cause some damage to the muscle of spinal cord injury patients. Further, steroid myopathy recovers naturally and the neurological improvement shown in the NASCIS may be just a recording of this natural motor recovery from the steroid myopathy, instead of any protection that methylprednisolone offers to the spinal cord injury. To our knowledge, this is the first discussion considering the possibility that the methylprednisolone recommended by NASCIS may cause acute corticosteroid myopathy.

Duplex ultrasound screening for deep vein thrombosis in spinal cord injured patients at rehabilitation admission.

OBJECTIVE: To determine the rate of deep vein thrombosis (DVT) newly diagnosed by duplex ultrasound in patients with acute spinal cord injury (SCI) at admission for rehabilitation. DESIGN: Retrospective case-control study. SETTING: Independent specialized spinal cord rehabilitation hospital. PATIENTS: Data were collected from records of 189 SCI patients admitted for rehabilitation over a 1-year period who underwent a duplex scan and were not admitted with a known diagnosis of DVT. MAIN OUTCOME MEASURES: A DVT newly diagnosed by duplex ultrasound at rehabilitation admission. RESULTS: Twenty-two patients (11.6%) had a newly diagnosed DVT at time of admission. Chi-square analysis found no statistically significant relationship between level of injury (tetraplegia vs paraplegia), motor complete (ASIA A and B) versus incomplete status (ASIA C and D), or cause of SCI (traumatic vs nontraumatic injury) in determining a positive or negative duplex result (chi2 = 1.709, p = .191; chi2 = 1.314, p = .252; chi2 = 3.155, p = .076; respectively). Prophylaxis for DVT decreased the risk of developing a DVT: 4.1% of patients administered prophylaxis as compared to 16.4% of patients not given prophylaxis (chi2 = 6.558, p = .01). Only 38.6% of patients transferred to rehabilitation were undergoing DVT prophylaxis. CONCLUSIONS: The prevalence of DVT in acute SCI patients at admission to rehabilitation is significant. A duplex ultrasound is an important noninvasive technique to screen patients with acute and subacute SCI for DVT on admission to the rehabilitation setting regardless of the completeness, level, or cause of the patients' injury.

Predictors of dysphagia after spinal cord injury.

OBJECTIVE: To quantify the incidence of swallowing deficits (dysphagia) and to identify factors that predict risk for dysphagia in the rehabilitation setting following acute traumatic spinal cord injury. DESIGN: Retrospective case-control study. SETTING: Freestanding rehabilitation hospital. PATIENTS: Data were collected on 187 patients with acute traumatic spinal cord injury admitted for rehabilitation over a 4-year period who underwent a swallowing screen, in which 42 underwent a videofluoroscopic swallowing study (VFSS). MAIN OUTCOME MEASURES: VFSS was performed on patients with suspected swallowing problems. Possible antecedents of dysphagia were recorded from the medical record including previous history of spine surgery, surgical approach and technique, tracheostomy and ventilator status, neurologic level of injury, ASIA Impairment Classification, orthosis, etiology of injury, age, and gender. RESULTS: On admission to rehabilitation 22.5% (n = 42) of spinal cord injury patients had symptoms suggesting dysphagia. In 73.8% (n = 31) of these cases, testing confirmed dysphagia (aspiration or requiring a modified diet), while VFSS ruled out dysphagia in 26.2% (n = 11) cases. Logistic regression and other analyses revealed three significant predictors of risk for dysphagia: age (p < .028), tracheostomy and mechanical ventilation (p < .001), and spinal surgery via an anterior cervical approach (p < .016). Other variables analyzed had no relation or at best a slight relation to dysphagia. Tracheostomy at admission was the strongest predictor of dysphagia. The combination of tracheostomy at rehabilitation admission and anterior surgical approach had an extremely high rate of dysphagia (48%). CONCLUSION: Swallowing abnormalities are present in a significant percentage of patients presenting to rehabilitation with acute traumatic cervical spinal cord injury. Patients with a tracheostomy appear to have a substantially increased risk of development of dysphagia, although other factors are also relevant. Risk of dysphagia should be evaluated to decrease the potential for morbidity related to swallowing abnormalities.

Treatment alternatives for spinal cord injury related spasticity.

Spasticity is a disorder of the motor system that occurs after injury to the central nervous system, which may increase the disability of an individual with spinal cord injury (SCI). Treatment options detailed in this review include rehabilitation techniques and modalities, pharmacological options, injection techniques, intrathecal baclofen, and surgery. This review will hopefully help health professionals to be aware of the treatment alternatives available for patients with SCI related spasticity.

Electromyogram-triggered neuromuscular stimulation for improving the arm function of acute stroke survivors: a randomized pilot study.

OBJECTIVE: To assess the efficacy of electromyogram (EMG)-triggered neuromuscular stimulation (EMG-stim) in enhancing upper extremity motor and functional recovery of acute stroke survivors. DESIGN: A pilot randomized, single-blinded clinical trial. SETTING: Freestanding inpatient rehabilitation facility. PATIENTS: Nine subjects who were within 6 weeks of their first unifocal, nonhemorrhagic stroke were randomly assigned to either the EMG-stim (n = 4) or control (n = 5) group. All subjects had a detectable EMG signal (>5 microV) from the surface of the paretic extensor carpi radialis and voluntary wrist extension in synergy or in isolation with muscle grade of <3/5. INTERVENTION: All subjects received two 30-minute sessions per day of wrist strengthening exercises with EMG-stim (experimental) or without (control) for the duration of their rehabilitation stay. MAIN OUTCOME MEASURES: Upper extremity Fugl-Meyer motor assessment and the feeding, grooming, and upper body dressing items of the Functional Independence Measure (FIM) were assessed at study entry and at discharge. RESULTS: Subjects treated with EMG-stim exhibited significantly greater gains in Fugl-Meyer (27.0 vs 10.4; p = .05), and FIM (6.0 vs 3.4; p = .02) scores compared with controls. CONCLUSION: Data suggest that EMG-stim enhances the arm function of acute stroke survivors.

Anodal block in F-wave studies.

OBJECTIVE: To determine whether F-wave results differ with the anode proximal or distal to the cathode, ie, if clinical anodal block exists. DESIGN: Prospective study of 30 healthy volunteers undergoing nerve conduction and F-wave studies in one median nerve. A needle cathode electrode was used with a surface anode placed alternately proximal and distal to the cathode. The same electromyographer performed all studies with a Dantec Counterpoint machine. RESULTS: F-wave latencies were essentially unaffected by distal versus proximal positioning. Minimum, maximum, and mean F-wave latencies correlated extremely highly (r=.973 to .988). For both F-wave and M-response latencies and amplitudes, differences between mean values obtained using the two methods were extremely small and were neither clinically nor statistically significant. The frequency of elicitation of F-waves may (p < .05) have been slightly (3.5%) lower when the anode was in the distal position. CONCLUSION: Anodal block is not seen in F-wave studies when using needle electrode stimulations. Reversing the stimulator does not seem to be required. Further study with surface stimulating electrodes is underway to confirm results.

Heparin-associated thrombocytopenia and thrombosis syndrome in a rehabilitation patient.

Heparin-associated thrombocytopenia and thrombosis (HATT) syndrome is a severe complication of heparin therapy. Since patients admitted for rehabilitation are at high risk for deep-vein thrombosis and pulmonary embolism, prophylactic doses of subcutaneous heparin are frequently used. We report the case of a 73-year-old woman with a history of heparin exposure, admitted to a comprehensive rehabilitation program for management of severe back pain. The patient was started on subcutaneous heparin. After 18 days of hospitalization, she developed marked thrombocytopenia and a massive venous thrombosis in the right lower extremity. On intravenous heparin therapy, the platelet count continued to decline. The thrombocytopenia resolved with discontinuation of heparin. This case illustrates a devastating complication of heparin therapy and emphasizes that physiatrists should be aware of this acute and preventable drug reaction.

Autonomic dysreflexia and foot and ankle surgery.

Autonomic dysreflexia is a syndrome of massive imbalance of reflex sympathetic discharge occurring in patients with spinal cord injury with a lesion above the splanchnic outflow (Thoracic 6). Autonomic dysreflexia is characterized by a sudden and severe rise in blood pressure and is potentially life threatening. Because the onset of this entity is rapid and the potential morbidity is severe, it is important for those caring for spinal cord injury patients to be aware of this syndrome. The paper presents a review of the literature, and familiarizes one with the diagnosis, pathophysiology, and treatment. Two illustrative case reports are also presented.

Practice and career satisfaction among physiatrists. A national survey.

To evaluate physiatrist career satisfaction and current practice patterns, a 15-page survey was mailed randomly to 400 fellow members of the American Academy of Physical Medicine and Rehabilitation. The 208 questionnaires (52%) returned revealed respondents' level of satisfaction with career choice, current practice, relationships with other physicians, their own residency training, and problems experienced that impede their practice. Factor analysis identified six areas of satisfaction: time demands, organizational support, current practice, current specialty, profession, and training. Problems with work consisted of four factors: external intrusions into practice, having to deal with non-rehabilitation problems, dealing with PM&R problems, and insufficient time for patients. Results showed that 75% of physiatrists were satisfied with their practice/profession. Satisfaction with current practice was greater with fewer external intrusions into practice, a larger percentage of income from traditional non-managed payment sources (including Medicaid), and less competition. Changes in health care, such as managed care, competition, and increased external regulations, appear to interfere with current practice. Variation in satisfaction was not significantly correlated with size of community, variation in rates of payment denials, workloads of greater than 50 hours per week, and a number of other factors that one might expect to affect satisfaction. Physiatrists had made many changes in their practice in response to the changes in the health care environment but had not cut care for indigent patients. Needs for greater residency training in outpatient clinics, physicians' offices, managed care, and long-term care settings were expressed. This is the first comprehensive published report on physiatric satisfaction in a changing health care environment. Further research in some of the areas will be required.

Development of an objective structured clinical examination (OSCE) for physical medicine and rehabilitation residents.

Clinical competency is poorly measured by knowledge-based written examinations. A five-station, four-interstation objective structured clinical examination (OSCE) has been developed in consultation with the National Board of Medical Examiners as a pilot study to standardize assessment methods that serve to evaluate the clinical competency of senior physical medicine and rehabilitation residents. Various stations demonstrating musculoskeletal and neurologic conditions commonly encountered in physiatric practice were included, incorporating the use of standardized patients into the OSCE format. This is a descriptive study of individual stations-evaluated history-taking, physical examination, and communication skills, whereas the interstations measured the residents' ability to write therapy and prosthetic/orthotic prescriptions, as well as interpret x-ray and electrodiagnostic data. The OSCE program development including case background, principal tasks, time allotment, evaluation objectives, performance criteria, therapeutic plan, standardized patients case descriptions, and assessment checklists as well as the training procedure is discussed. Additionally, cost analysis and scheduling issues are reviewed. This information should aid other training programs or consortiums in developing similar clinical evaluation tools.

Further experience in development of an objective structured clinical examination for physical medicine and rehabilitation residents.

Since the last report, two additional objective structured clinical examinations (PGY-2, PGY-3, and PGY-4, as well as incoming PGY-2) have been administered. As a result, our curriculum has been modified to strengthen physical examination skills, including specific workshops. Interrater reliability of evaluators has been tested for the first time to verify reliability, and refinements have been made in the standardized checklist grading system. The interrater grading of history-taking had good reliability (0.73-0.96), as did neurological and spine physical examination (0.84-0.88). The interrater grading reliability of small and large joint examination was more problematic (0.46-0.62) because of examiners' inability to have full visibility, evaluator's fatigue, and confusing evaluation scoring descriptions. We now use a two-point grading scale (correct or incorrect) for history but continue a three-point scale (correct, partially correct, or incorrect) for physical examination. The examination schedule is being modified to add more encounters, give time for trainee feedback, and further refinement of grading expectations for a more efficient and reliable scoring system.
