Recovery from complete hemiplegia following resection of a retrocentral metastasis: the prognostic value of intraoperative cortical stimulation.

The goal in this study was to determine if intraoperative electrical stimulation mapping is useful during surgical resection of lesions located in the central region, even in cases of preoperative hemiplegia. This 45-year-old man with a retrocentral metastasis from an embryonal carcinoma of the testis suffered an acute complete hemiplegia after intratumoral bleeding. Emergency surgery was performed with the aid of intraoperative motor mapping despite the preoperative deficit. Cortical stimulations (CSs) elicited motor responses, allowing the detection and hence preservation of the primary motor area during tumor removal. Postoperatively, the patient recovered almost completely within 1 week; the tumor resection was total. It is possible that CSs give an early and valuable prognostic indicator of motor recovery in cases of complete hemiplegia, at least in patients with acute onset and short duration of the deficit. Consequently, if motor responses can be elicited by CSs, it becomes mandatory for the surgeon to respect the primary motor area despite the preoperative hemiplegia, with the aim of preserving the chances of an eventual recovery.

Pure motor hemiplegia with conjugate lateral gaze palsy in pontine lacunar infarction.

The combination of pure motor hemiplegia and horizontal gaze palsy is a rare but identifiable lacunar syndrome. Among horizontal gaze palsies, one-and-a-half syndrome and abducens nerve palsy are reported to be associated with pure motor hemiplegia in pontine lacunar infarction. Although conjugate lateral gaze palsy is also hypothesized, pure motor hemiplegia with conjugate lateral gaze palsy has never been reported. We present a 75-year-old man who showed right hemiparesis and impaired left horizontal conjugate eyeball movement. Both the findings of the brain CT scan and those of the MRI study were consistent with a small infarction in the left midpontine tegmentum. Magnetic resonance angiography revealed no stenotic narrowing of the vertebrobasilar artery. Radiological findings suggested that pure motor hemiplegia with conjugate lateral gaze palsy, in our patient, might have been produced by the occlusion of a single penetrating branch of the basilar artery.

Effects of a program on symmetrical posture in patients with hemiplegia: A single-subject design.

OBJECTIVES: Asymmetrical posture during static stance has been identified as a common problem in persons with hemiplegia. This study examined the effect of an activity-based therapy regimen on symmetric weight bearing and midline position of center of gravity (COG) in three adult subjects with hemiplegia. METHOD: An ABAB single-subject design was used. The intervention program, including sanding in front of a standing table and play a bean bag game, was introduced for 30 min each day during each intervention phase. Quantitative measurements of the weight distribution and the midline position of COG were taken with the Balance Master System (version 2.20). RESULTS: Visual inspection and statistical analysis of the data revealed a significant improvement in symmetric weight distribution and midline position of COG. The study suggests that this program may be a promising alternative to a variety of postural rehabilitation programs for persons with hemiplegia. CONCLUSION: Insecurity caused by poor stabilization and abnormal reactions to body weight bearing in an antigravity position might contribute to asymmetric postures. Results of this study suggest that an activity-oriented program can be effective in helping the persons with hemiplegia achieve symmetric stances.

Prognostic factors in congenital hemiplegia in full-term and preterm children.

OBJECTIVES: To determine whether the cerebral CT scan patterns, the type of E.E.G recording, the gestational age, the etiological factors and the side of hemiplegia would influence the functional prognosis in congenital hemiplegia. MATERIAL AND METHODS: 53 children (35 males, 18 females) suffering from congenital hemiplegia were included in the study. They were divided into prematures (16 cases) and full-term children (37 cases). All of them were evaluated for I.Q level, motor performance and language ability. CT scan was performed in all cases and E.E.G recording in the majority of them. RESULTS: Full-term gestational age, cortical and subcortical lesions in term children, irritative E.E.G recording and hemispheric atrophy in both gestational age groups were found to be bad prognostic indicators for functional status in congenital cerebral hemiplegia.

[Anosognosia for hemiplegia in a patient with pontine infarction].

We report a patient with anosognosia for hemiplegia associated with a right pontine infarction. A 51-year-old woman with histories of hypertension and diabetes mellitus was admitted because of weakness of her left upper and lower extremities. On neurologic examination, she was alert and oriented without dementia. Visuospatial hemineglect was not present. Hemiparesis of her left upper and lower extremities was noted. Her brain MRIs showed a large infarction in the right pons. On admission, she could recognize her illness but was indifferent to her hemiplegia, so she said that there was not well-off for her life. Two weeks after the onset, her neurological symptoms gradually improved. Simultaneously, her interest in her hemiparesis increased. We proposed that, in the present patient, anosognosia for hemiplegia was caused by the pontine infarction. Since pontine anosognosia for hemiplegia has been rarely reported to date, it is expected that the findings of the present patient will be useful to the better understanding of mechanisms underlying anosognosia.

Acute hemiplegia of childhood.

Acute hemiplegia of obscure cause occurred in 28 children: 13 had had prolonged seizures and a high temperature (considered to have been the direct cause of the brain damage); 5 had had brief seizures, a lower temperature and a depressed level of consciousness; and 10 had a nonfebrile onset of hemiplegia and were found to have vascular abnormalities. Most of the first group were retarded and epileptic at long-term follow-up, as were about half of the second group, whereas children in the third group were of normal intelligence and epilepsy was uncommon among them. Hemiplegia persisted at follow-up in most of the children in each group, the proportion being at least in the third group; if cerebral angiography had demonstrated carotid stenosis or occlusion there was usually poor recovery from the hemiplegia. Bilateral changes on plain skull films or pneumoencephalograms were associated with mental retardation. Failure to control prolonged seizures accompanied by a high temperature predisposes to brain damage; therefore, early and vigorous management is essential.

[Postoperative transient hemiplegia after resection of the medial frontal tumor involving the supplementary motor area: report of two cases].

The supplementary motor cortex (SMA) is located anterior to the primary motor cortex, and is considered to play an important role in planning, initiating and maintaining sequential motor actions. Disturbance of this area sometimes causes severe contralateral hemiplegia. If the disturbance doesn't affect the primary motor cortex, motor function will recover in relatively early postoperative time. We encountered two cases in which the patients developed postoperative severe hemiplegia after resection of a medial frontal lobe glioma, although there was no apparent change shown in the monitoring of intraoperative motor evoked potential (MEP). Both cases recovered from hemiplegia in the early postoperative period. In our cases, the disturbances of SMA were considered to be the causes of the development of transient hemiplegia. Intraoperative MEP monitoring is useful to distinguish the damage of the primary motor area from that of the SMA.

[Alternating hemiplegia of childhood treated as epilepsy. Two new cases].

INTRODUCTION: Alternating hemiplegia (AH) of childhood is a rare disease that gives rise to transient attacks of hemiplegia that may affect either side of the body indistinctly, or even both sides at the same time. Onset occurs before the age of 18 months and in some cases there are neonatal symptoms such as abnormal eye movements, especially nystagmus, and dystonic or tonic seizures. Attacks of hemiplegia, which disappear during sleep, begin before the age of one year. These symptoms can initially be taken for an epileptic disorder. CASE REPORTS: We describe the study of two male patients whose clinical symptoms appeared at the age of 6 months, with tonic seizures, upward deviation of gaze, without loss of consciousness, which occurred with a recurrence rate of between one and two attacks a week or several times a day. They were initially treated with antiepileptic drugs (AED), although the complementary tests, including electroencephalogram (EEG), computerised axial tomography (TAC), magnetic resonance (MR) scans and metabolic tests, were all normal. CONCLUSIONS: Since, to date, no specific test has been confirmed for the disease, diagnosis is essentially clinical and by exclusion. Treatment is symptomatic using flunarizine. In one of our cases, administration of a single 10 mg/day dose this drug at night lowered the frequency of the attacks of hemiplegia. The possibility of treating a patient who is a carrier of an AH with AED makes early knowledge and identification of this disease necessary in order to be able to improve the patient's prognosis.

Histologic evaluation of nerve muscle pedicle graft used as a treatment for left laryngeal hemiplegia in standardbreds.

A nerve muscle pedicle (NMP) graft was placed in the cricoarytenoideus dorsalis (CAD) muscle of 6 horses with induced left laryngeal hemiplegia. The NMP graft was created by use of the first cervical nerve and omohyoideus muscle. In 1 horse (control), the first cervical nerve was transected after placement of the NMP graft. One year after the surgical procedure, horses were examined endoscopically and then anesthetized. While the larynx was observed endoscopically, the first cervical nerve was stimulated. Horses were subsequently euthanatized, and the larynx was harvested. Prior to anesthesia, the endoscopic appearance of the larynx of all horses was typical of laryngeal hemiplegia. During anesthesia, stimulation of the first cervical nerve produced vigorous abduction of the left arytenoid in principal horses but not in the control horse. The right cricoarytenoideus lateralis and CAD muscles were grossly and histologically normal. Also, the left cricoarytenoideus lateralis was atrophic in all horses as was the left CAD muscle of the control horse. In contrast, the left CAD muscle harvested from principal horses had evidence of reinnervation with type 1 or type 2 fiber grouping. One year after the NMP graft procedure, horses with left laryngeal hemiplegia had reinnervation of the left CAD muscle. In another study, reinnervation was sufficient to allow normal laryngeal function during exercise. Combined, these data suggest that the NMP graft procedure is a viable technique for the treatment of left laryngeal hemiplegia in horses.

[Transient hypoglycemic hemiplegia due to insulin autoimmune syndrome--a case report].

Hypoglycemia causes a variety of neurologic symptoms, and yet it is rarely responsible for such a sudden, focal neurologic deficit as hemiplegia. Herein we described a rare case of what was believed to be transient hypoglycemic hemiplegia. An 80-year-old woman was admitted to the hospital on June 10, 1988, following frequent episodes of abnormal behavior and transient weakness of the right extremities. These symptoms, similar to those of cerebrovascular diseases, characteristically occurred early in the morning and disappeared after breakfast. On admission no definite abnormalities were disclosed on neurologic examination. Neuroradiological evaluations by CT, cerebral angiography and single photon emission CT failed to demonstrate abnormalities. The patient remained stable until the following morning, when she suddenly became restless and confused and developed total aphasia and the right hemiplegia. The blood sugar was estimated to be 34 mg/dl and electroencephalogram (EEG) showed continuous slow wave activities involving the bilateral fronto-parietal region. Intravenous injection of glucose solution instantaneously resulted in disappearance of both neurologic symptoms and EEG abnormality. Serum insulin level was found extremely increased ranging from 7000 to 8000 microU, eventually leading to a diagnosis of insulin autoimmune syndrome. Hemiplegia due to hypoglycemic attack was reviewed in the literature, and the pathogenesis and EEG findings were also discussed.

[A patient with alternating hemiplegia in childhood].

Alternating hemiplegia in childhood (Verret, 1971) is a disorder presenting with frequent episodes of alternating hemiplegia from early infancy. We report a patient with this disorder, along with a pathophysiological study and a discussion about the available therapies for this disorder. The patient, an 11-year-old boy, visited our hospital with episodes of alternating hemiplegia from early infancy. His family history showed that many members suffered from migraine. He was born with asphyxia. Mental and motor developmental delays were seen from early infancy. The hemiplegic episodes with ipsilateral facial palsy had occurred frequently from early infancy. The episodes were frequently induced by emotional stress. The duration of hemiplegia varied from 10 minutes to 3 days. From the age of 11 years, he had begun to have migrainous attacks with or without hemiplegic episodes. Neurological examination revealed slight muscle hypotonia, choreoathetosis and dystonic movements induced by locomotion, positive Myerson sign, increased deep tendon reflexes and Babinski reflex. CAG, VAG and CAT revealed normal findings. EEG revealed diffuse generalized slowing during hemiplegic episodes. Measurement of regional cerebral blood flow (CBF) by 133Xe inhalation method revealed a slight decrease of bilateral CBF during a quadriplegic episode. Positron emission tomography using C15O2 revealed a slight decrease of CBF at the insula, putamen and claustrum of the left side during a right sided episode. Increased excretion of urinary 5-HIAA was seen during one episode. From our clinical and laboratory findings, we think this disorder may be a special type of migraine. Therapeutic trials of diazepam and flunarizine were both effective, but the initial effectiveness was decreased after 5 months.

[Hemiplegia during carbon monoxide poisoning revealing multiple cerebral artery abnormalities including the hypoglossal artery].

Hemiplegia after carbon monoxide (CO) poisoning is rare since only 9 such lesions have been reported from among 1480 cases of poisoning. The patient reported was a 43 year-old man with a left hemiplegia with coma following CO poisoning. Right carotid angiography demonstrated a hypoglossal artery supplying both posterior cerebral arteries. Left carotid angiography showed a dolichocarotid artery supplying the territories of the anterior and middle cerebral arteries on both sides. Complete regression of the hemiplegia occurred after 2 months following rapid administration of hyperbaric oxygen. Normal CT scan images and cerebral blood flow rates on follow-up examination suggest that the left hemiplegia was due to the combined effects of arterial anomalies and CO poisoning.

Early diagnosis of spastic diplegia, spastic hemiplegia, and quadriplegia.

A retrospective study examined early neurodevelopmental behaviors of children with spastic diplegia, spastic hemiplegia, and quadriplegia (spastic, athetoid, or mixed) who had been followed up longitudinally in a high-risk infant follow-up clinic. Compared with peers with normal outcomes, children with all three types of cerebral palsy had significantly lower scores on the Bayley Mental Scale at 4 months of age; children with hemiplegia and quadriplegia also scored significantly lower on the Bayley Motor Scale. On the Movement Assessment of Infants at 4 months of age, the children with hemiplegia and quadriplegia showed significantly higher risk scores than the nonhandicapped group. The Movement Assessment of Infants was more than three times as sensitive as the Bayley Motor Scale in detecting motor abnormalities in 4-month-old infants with diplegia and more than twice as sensitive in detecting early abnormalities of hemiplegia. At 1 year of age, however, the Bayley Motor Scale was extremely sensitive in picking up motor deficits in children with all three types of cerebral palsy.

Interobserver and intraobserver reliability of therapist-assisted videotaped evaluations of upper-limb hemiplegia.

PURPOSE: Therapist-assisted videotaped sessions have been used to augment physical examinations in the evaluation of hand and arm function in patients with spastic hemiplegia. The purpose of this study was to assess the interobserver and intraobserver reliability of standardized videotaped examinations in the evaluation and functional classification of these patients. METHODS: Three examiners reviewed standardized videotaped examinations of 10 adolescents with spastic hemiplegia on 2 separate occasions. All 10 patients were under consideration for surgical intervention for their upper-extremity dysfunction. Videotapes were used to assess upper-extremity range of motion, finger and thumb deformity, and reach, pinch, and grip function. Upper-extremity function was graded according to the House and Mowery classification systems. Interobserver and intraobserver reliabilities were measured with the kappa coefficient. RESULTS: Range of motion, deformity, and upper-extremity functional strategy assessment showed slight to excellent interobserver reliability and good to almost perfect intraobserver reliability. Interobserver and intraobserver reliability of the consolidated House classification system was more reliable than the Mowery or standard House classification systems. CONCLUSIONS: Evaluations of standardized videotaped examinations in patients with hemiplegia were reliable between and among observers. Such therapist-assisted videotaped evaluations may provide useful data for clinical decision-making and multicenter outcomes studies in patients with upper-extremity involvement with spastic hemiplegia.

[Effect of electroacupuncture combined with suspension exercise therapy on lower limb motor function in elderly patients with post-stroke spastic hemiplegia].

OBJECTIVE: To observe the efficacy of electroacupuncture (EA) combined with suspension exercise therapy in elderly patients with post-stroke spastic hemiplegia and its effect on lower limb motor function. METHODS: A total of 120 elderly patients with post-stroke spastic hemiplegia were enrolled. Using a 2×2 factorial design, all the patients were assigned to a group A (conventional treatment), a group B (conventional treatment combined with suspension exercise therapy), a group C (conventional treatment combined with EA at Jiaji [EX-B2] and limb acupoints), and a group D(conventional treatment combined with suspension exercise therapy and EA at Jiaji [EX-B2] and limb acupoints), with 30 patients in each group. The main acupoints were bilateral Jiaji (EX-B2) points at the C2-C7, T2-T12, L1-L5, and S1 segments. The adjunct acupoints included Jianyu (LI15), Binao (LI14), Huantiao (GB30), Chengfu (BL36), etc. on the affected side.Continuous wave was applied at a frequency of 100 Hz with a current intensity of 1.5-3.0 mA, and needles were retained for 30 min, once daily for 4 weeks. Before treatment and after 2 and 4 weeks of treatment, the modified Ashworth scale (MAS),Fugl-Meyer assessment (FMA), Berg balance scale (BBS), and Barthel index scores were evaluated in the four groups. Root mean square (RMS) values of surface electromyography (sEMG) of the erector spinae and rectus abdominis muscles on the affected side, as well as balance function indexes, including the mean pressure symmetry index (SI), contact area SI, ellipse area, and displacement distances of the center of pressure in the anteroposterior (AP) and mediolateral (ML) directions, were measured. Clinical efficacy was also compared among the four groups. RESULTS: After 2 and 4 weeks of treatment, MAS scores in all groups were lower than those before treatment (P<0.05), whereas FMA, BBS, and Barthel index scores were higher than those before treatment (P<0.05). After 4 weeks of treatment, MAS scores were lower than those after 2 weeks of treatment (P<0.05), whereas FMA, BBS, and Barthel index scores were higher than those after 2 weeks of treatment (P<0.05) in the four groups. At both 2 and 4 weeks after treatment, group D had lower MAS scores (P<0.05) and higher FMA,BBS, and Barthel index scores (P<0.05) than the other three groups. After 2 and 4 weeks of treatment, RMS values of sEMG of the erector spinae and rectus abdominis muscles on the affected side at all tested angles were higher than those before treatment in all groups (P<0.05), and the values after 4 weeks of treatment were higher than those after 2 weeks of treatment(P<0.05). At both 2 and 4 weeks after treatment, all these indexes in the group D were higher than those in the other three groups (P<0.05). After 2 and 4 weeks of treatment, the mean pressure SI, contact area SI and ellipse area of each group were lower than those before treatment (P<0.05). After 4 weeks of treatment, the mean pressure SI, contact area SI and ellipse area of each group were lower than those after 2 weeks of treatment (P<0.05). After 2 and 4 weeks of treatment, the AP displacement distances of groups A, C and D were lower than those before treatment (P<0.05), and after 4 weeks of treatment, the AP displacement distances of groups A, C and D were lower than those after 2 weeks of treatment (P<0.05);after 2 weeks of treatment, there was no statistically significant difference in AP displacement distance in the group B compared with before treatment (P>0.05), and after 4 weeks of treatment, the AP displacement distance of group B was lower than that before treatment (P<0.05). After 2 weeks of treatment, there was no statistically significant difference in ML displacement distance in group A compared with before treatment (P>0.05); after 4 weeks of treatment, the ML displacement distance of group A was lower than that before treatment (P<0.05). After 2 and 4 weeks of treatment, there was no statistically significant difference in ML displacement distance in the group B compared with that before treatment (P>0.05).After 2 and 4 weeks of treatment, the ML displacement distances of groups C and D were lower than those before treatment(P<0.05), and after 4 weeks of treatment, the ML displacement distances of groups C and D were lower than those after 2 weeks of treatment (P<0.05). At both 2 and 4 weeks after treatment, mean pressure SI, contact area SI, ellipse area, and AP and ML displacement distances in the group D were lower than those in the other three groups (P<0.05). Factorial analysis of variance showed that EA had the strongest main effect on FMA score (F=6.243, P<0.05), suspension exercise therapy had the strongest main effect on BBS score (F=6.292, P<0.05), and the interaction effect was most significant for MAS score (F=5.941, P<0.05), indicating that the combined therapy produced a greater synergistic effect on reducing muscle tone than on the other outcome measures. The total effective rate in the group D was 93.3% (28/30), which was higher than those in the group A (53.3% [16/30]), group B (56.7% [17/30]), and group C (66.7% [20/30], P<0.05). CONCLUSION: EA combined with suspension exercise therapy could effectively promote the recovery of lower limb function in elderly patients with post-stroke spastic hemiplegia, improve motor and balance functions, and enhance activities of daily living.

Hypoglycemia masquerading as cerebrovascular disease (hypoglycemic hemiplegia).

Hypoglycemia produced hemiplegia with right-sided predilection in 16 patients initially suspected of having suffered a stroke. Fifteen patients had no demonstrable brain disease, and the hemiplegia cleared rapidly once the hypoglycemia was corrected. Invasive investigations such as carotid arteriography are not required in most patients. The features of hypoglycemia hemiplegia suggest that a selective neuronal vulnerability and not underlying focal brain disease is responsible in most cases.

Alternating hemiplegia of childhood: studies of regional cerebral blood flow using 99mTc-hexamethylpropylene amine oxime single-photon emission computed tomography.

Alternating hemiplegia of childhood is a rare disorder of unknown cause associated with progressive neurological deterioration. We report the results of regional cerebral blood flow studies using 99mTc-hexamethylpropylene amine oxime single-photon emission computed tomography in 3 patients. These studies were performed during the hemiplegic attacks (n = 6) and during the symptom-free periods (n = 2). Six single-photon emission computed tomographic studies performed during hemiplegic attacks consistently showed relative hyperperfusion of the contralateral cerebral hemisphere. Two single-photon emission computed tomographic studies performed during the asymptomatic phase showed normal and symmetrical cerebral perfusion. This is the first definite demonstration of unilateral increase of cerebral blood flow in alternating hemiplegia. These findings support the possibility of a relationship between the cause of alternating hemiplegia and migraine.

Skeletal muscle mitochondrial dysfunction in alternating hemiplegia of childhood.

Alternating hemiplegia of childhood is an uncommon disease characterized by repeated, transient attacks of hemiplegia. Its pathophysiology is uncertain, but attention recently has focused on possible mitochondrial abnormalities. Using 31P magnetic resonance spectroscopy, we studied gastrocnemius muscle in 5 patients with alternating hemiplegia, aged 8 to 30 (mean, 18) years, at rest and during incremental aerobic exercise and recovery. There were no significant differences in resting muscle between patients and a control group aged 7 to 42 (mean, 19) years. Exercise performance was grossly impaired in the patients, the mean duration being 30% of normal. The total change in pH during exercise was somewhat less than in control subjects, while the changes in phosphocreatine concentration and intracellular ADP were similar. Thus the average overall rate of fall of phosphocreatine concentration during exercise was three-fold greater than in control subjects. However, the initial rate of ATP turnover at the start of exercise (a measure of muscle mass and efficiency) was not abnormal. During recovery, both the initial rate of phosphocreatine resynthesis and the calculated mitochondrial capacity were reduced by about 35%. This mitochondrial defect probably explains most of the abnormalities seen during exercise.
