Plastic ankle-foot orthoses (PAFOs) are worn by persons with hemiplegia to correct gait abnormalities such as foot drop during swing and insufficient pushoff during stance. A PAFO should resist plantarflexion sufficiently to provide toe clearance during the swing phase of gait without excessively increasing the knee bending moment during heelstrike. It should resist dorsiflexion during late stance to raise the heel to simulate gastrocnemiussoleus muscle group function. Five PAFOs were evaluated as to the amount of plantarflexion-dorsiflexion resistance that was provided when worn by hemiplegic and able-bodied subjects. A self-aligning goniometer measured ankle angle as the subject walked, and a gait event marker system recorded occurrences of gait events. The Seattle design polypropylene orthosis which enclosed the malleoli was the least flexible; it provided the greatest plantarflexion resistance to ensure against toe drag during swing for patients with severe plantarflexion spasticity. It offered the greatest dorsiflexion resistance to provide a good substitute for the gastrocnemiussoleus during the latter part of stance as required by patients with flaccid plantarflexors and full ankle range of motion. Progressive trimming of the Seattle design polypropylene orthosis made it more flexible and comparable in function to the commercially available Engen and Teufel orthoses. The latter 2 orthoses did not provide a pushoff substitute as well as the Seattle design orthosis which enclosed the malleoli, but they did provide an adequate amount of toe clearance during swing. The more flexible orthoses would be appropriate for subjects with mild to moderate plantarflexor spasticity.

It is commonly observed in patients with established hemiplegia following cerebrovascular accidents (CVA), that the skin temperature (Ts) of the leg and foot is notably cooler on the affected side of the body; the relationship to cutaneous blood flow, however, has not previously been investigated. In the present study, observations of foot and calf blood flow via venous occlusion plethysmography in water were made in six patients with hemiplegia of 5-13 months duration, both at observed Ts and at standard temperature (ST). Similar measurements were obtained on six age-matched control subjects. The patients' mean Ts values for the foot and calf were significantly lower on the affected side, while those for the nonaffected side were not significantly different from control group values. At non-equivalent water temperatures (Tw) blood flows in the patients' affected feet were lower than those on the nonaffected side, but at the ST they were similar. Further, under these conditions, the flows in both feet were lower than in control subjects. Flows in the patients' affected calves were not significantly reduced at non-equivalent TW; at the ST they did not differ significantly from those of the controls. These observations suggest that, in patients who have suffered a stroke, the reduction of TS of the affected limb is associated with reduced limb blood flow, which cannot be attributed to changes in limb tissue composition. Since the reduced limb blood flow on the affected side is more marked in the foot, it is likely to be due to reduction of blood flow in the skin. In addition, the reduction of flow in the foot of the nonaffected leg suggests a more generalized change of skin circulation in these patients.

Four patients with infantile hemiplegia who had undergone hemispherectomy were examined. both left (LH) and right (RH) hemidecorticates obtained borderline defective scores on IQ tests. Patients with isolated right hemispheres were found not to be aphasic or apraxic. Visuospatial and constructional capacities were compromised in all patients. Individuals with an isolated right hemisphere smiled and gestured more than did those with an isolated right hemisphere. EEG and CT scan data showed that the remaining hemisphere was not normal in these patients. Therefore, inferences regarding the functional plasticity of the remaining hemisphere must be made with caution.

A flexible fiberoptic endoscope was used to examine the upper respiratory tract of 479 horses and 41 (8.6%) had abnormalities. Pharyngeal lymphoid hyperplasia (PLH) was found in 141 horses (29.5%). Statistical analysis showed a relationship between the age of the horse and the prevalence of PLH. Sixteen (3.3%), 10 (2.1%), and 6 (1.3%), of the horses had laryngeal hemiplegia, epiglottic entrapment, and dorsal displacement of the soft palate, respectively. There was no association between the age of the horse and the prevalence of any of these abnormalities; nor was there a positive correlation between the prevalence of exercise-induced pulmonary hemorrhage and PLH or laryngeal hemiplegia.

A follow-up study was undertaken in order to investigate the outcome of recovery from right and left hemiplegia on simple motor function and activities of daily living. The role of concomitant neurophysiological deficits was also investigated. The main results indicate that after six months from onset, left hemiplegics show a lesser degree of improvement in independence and social adjustment coupled with a tendency to a poorer recovery of motor function than the corresponding group of right hemiplegics. Unilateral spatial neglect, which is more frequent and severe in the group of left hemiplegics, seems to be crucial in hampering their performance.

A 57-year-old woman complained of severe headache and vomiting of a week's duration. Spinal tap showed bloody CSF and cerebral angiography revealed the "true" posterior communicating artery aneurysm. Left frontotemporal osteoplastic craniotomy and trapping of the aneurysm were performed on August 28, 1979. After operation right hemiplegia, left oculomotor palsy and the disturbance of consciousness developed. Postoperative CT scan showed a hemorrhagic infarction at the left basal ganglia. Since then she has been getting better and was discharged, able to walk, from our hospital 6 months after operation. We considered the anatomical importance of perforating arteries from posterior communicating artery and propose that true posterior communicating artery aneurysm should be classified separately from our experiences and literature.

The signs, symptoms and courses of 64 cases of "primary" haematoma of the basal ganglia have been retrospectively studied, and the main clinical data have been analyzed in relation to the location and extent of the bleeding. Onset with hemiplegia, accompanied or not by impaired consciousness, was more frequent with intermediate and lateral haematomas than with medial haematomas (p less than 0.001). Among patients with initial hemiplegia, impaired consciousness was more frequent with intermediate and medial haematomas than with lateral haematomas (p less than 0.005). At a later stage, patients with intermediate and lateral haematomas more often went into deep coma than those with medial haematomas (p less than 0.01). There were no statistically significant differences between the three anatomical groups with regard to frequency of other signs and symptoms or duration of the disease before death occurred.

A mother and son suffer from hemiplegic migraine with onset in childhood. Both have nystagmus which has not changed for many years, but the date of onset is uncertain. They have an asymmetrical tremor, clinically indistinguishable from essential tremor. Neuroophthalmological examination revealed inability to produce smooth pursuit, gaze-paretic nystagmus, rebound nystagmus, failure of fixation suppression of the vestibuloocular reflex both horizontally and vertically, and low gain of the optokinetic system. These abnormalities, confirmed by electrooculography, are commonly seen in disease of the cerebellum and brainstem. Treatment with propranolol and pizotyline lessened the number of episodes of hemiplegia and improved the tremor. Hemiplegic migraine has been reported in association with nystagmus, retinal degeneration, deafness, and ataxia in varying combinations in three other families with autosomal dominant inheritance. These associated neurological manifestations likely represent system degenerations rather than the effect of repeated ischemia imputable to the migraine itself. The syndrome of hemiplegic migraine, tremor, and ocular smooth pursuit system disorder seen in this family appears to be inherited as a single autosomal dominant trait, although more than one autosomal dominant gene may be involved.

We assessed the functional results of simultaneous proximal carpal carpectomy and radius to distal carpal row arthrodesis. A retrospective review of patients undergoing wrist arthrodesis for degenerative joint disease was performed. Patients with rheumatoid arthritis or spastic hemiplegia were excluded. Simultaneous proximal row carpectomy and radius to distal carpal row arthrodesis was performed in 38 patients using AO plates and 3.5 mm diameter screws. The mean follow-up time was 16 months, the fusion rate was 100%, and the average grip strength was 24 kg force or 79% of the contralateral hand measured at 10 degrees wrist extension. Patients with three or more screws placed in the metacarpal had significantly more plate-related complications and a higher rate of plate removal than those with two screws distally. Simultaneous proximal row carpectomy and radius to distal carpal row arthrodesis did not decrease the postoperative grip strength.

Over a 15-month period ending in July 1992, 9 patients (7 male, 2 female; mean age 67 years) with recurrent stenosis of the internal carotid artery underwent transluminal angioplasty (TLA). The mean interval between endarterectomy and treatment of recurrent stenosis was 45 months (range: 9 to 84 months). All patients were symptomatic except one with extensive bilateral carotid dysplasia. Three patients had recurrence proximal to the endarterectomized segment (Group I); in one of these patients the narrowing was extensive. The other 6 patients (Group II) demonstrated stenoses distally. In one of these latter patients, the narrowing developed in a vein bypass. Balloon dilation was performed by the surgical route in 3 patients and percutaneously in the other 6. Perioperative transcranial Doppler (TCD) monitoring was employed in all procedures. Postoperative treatment consisted of oral Ticlopicine. In Group I (proximal recurrence), immediate complications included one case of reversible spasm and two dissections that led to acute thrombosis treated by emergency bypass and to sylvian artery embolism complicated by transient hemiplegia. In Group II (distal disease), dissection was not encountered, and only one case of transient neurologic manifestations due to cerebral edema following reperfusion was observed. Mean follow-up has been 18 months (range: 9 to 24 months). All patients are presently asymptomatic. In Group II, 2 patients presented with secondary recurrence at 6 months and were treated again by angioplasty. In one of these cases, a Palmaz stent was placed to prevent restenosis by elastic recoil.(ABSTRACT TRUNCATED AT 250 WORDS)
