PURPOSE: Postoperative strength of knee flexor and extensor, and functional evaluation after arthroscopic menisectomy of the knee was evaluated objectively at the time of returning to daily life. MATERIALS AND METHODS: The 31 knees (29 patients) had meniscal injuries without associated ligament injury. The muscle strength was tested with Cybex 340 isokinetic dynamometer preoperatively and at 2, 4, 6, 10 weeks postoperatively. Clinical evaluation by Lysholm scoring system was also done simultaneously. The statistical analysis was evaluated by repeated measures of ANOVA. RESULTS: Muscle strength of extensor (quadriceps) was abruptly decreased to about 45% torque of the preoperative level at postop 2 weeks, but slowly increased to about 90% torque at 10 weeks in 90 degree/sec and 180 degree/sec exercise. The flexor strength was also a little bit decreased at post-op 2 weeks, slowly increased to about 120%-150% torque of preoperative level in 90 degree/sec and 180 degree/sec exercise at post-op 10 weeks. The clinical evaluation by Lysholm scale showed 45 points at postop 2 weeks and slowly improved to 80 points at post-op 10 weeks. CONCLUSIONS: Muscle weakness of knee extensor and flexor remained in isokinetic test at post-op 4-6 weeks. The recovery rate for weakness of hamstrings was faster than quadriceps. The rehabilitation of quadriceps should be accentuated in the prevention of knee injury due to muscle weakness.

Journal of the Korean Neurological Association 1992;10(4):420-427
Repetitive nerve stimulation test (RNS) is an easy and non-invasive test which provides objective for the presence of a myasthenic neuromuscular defect and for monitoring possible improvement through various therapeutic measures, and makes the differentiation of neuromuscular junction disorders. Analysing the RNS test of 45 normal controls and 146 patients with myasthenia gravis quantitatively, the following results obtained. 1. At low rate stimulation, the decremental response upto 2 standard deviation in normal control are 7.1% in orbicularis oculi(~), 7.6% in flexor carpi ulnaris (FCU) and 5.4% in abductor digiti guinti muscle(ADQ). There are two kinds of facilitation noticed: incremental responses at repetitive low stimulation (13.3-14.9%) immediately after tetanic stimulationy and increased mean amplitudes of compound muscle action potentials after exercise(l3-17%). Four minutes after the tetanic stimulation, the decremental responses at low rate stimulation become accentuated slightly even in normal control group. 2. At low rate stimulation. There are singificant decremental decremental responses in patients with myasthenia gravis, but statistically no significant differences are seen in the quantity of decremental responses among 2, 3 and 5/sec rate of stimulation. 3. The pattern and severity of decremental responses at low rate stimulation are depending on the clinical type of generalized myasthenia gravis. There are no decremental responses in FCU or ADQ in ocular type. The decremental responses of oo are greater than that of FCU in mild generalize myasthenia, but the reverse is true in moderate generalized type. 4. Statistically significant post-tetanic facilitation and exhaustion are noticed in patients with generalized myasthenia gravis.

Observing a 16 years old male of classical Friedreich's ataxia with progressive ataxia, dysarthria, areflexia, loss of vibration and proprioception, Babinski sign, pes cavus, scoliosis, hyperglycemia, optic atrophy and hearing deficits, the nerve conduction studies and several evoked potential studies are performed. The sensory nerve potentials are markedly decreased in amplitude and the average technique has to be used to get the potentials, worse distally. The motor nerve functions, however, are normal. There is no consistent waves recorded on BAEP even with maximal stimulation bilaterally. VEP reveals prolonged latencies bilaterally but with normal amplitudes. On median nerve SEP stimulated at wrist, the amplitudes of potentials at Erb's point look decreased and no definite evoked potentials are recored at contralateral scalp. In contrast, the cervical evoked potentials are normal in amplitudes and latencies.

One month following carbon monoxide poisoning, a 39 year-old man developed incontinence, memory impairment, disorientation and emotional instability. He was hospitalized 7weeks later, and during hospitalization he exhibited myoclonic movements of the neck and lower limbs. He was given piracetam intravenously for 11 days. The myoclonus was significantly reduced by the third day of treatment and had disappeared by the seventh day. There was no recurrence following cessation of treatment.

We report a case of acute transient encephalopathy with mental alteration, myoclonic jerks, and periodic triphasic wave electroencephalographic patterns caused by a therapeutic dose of baclofen. The clinical and electroencephalo-graphic abnormalities improved to a normal range shortly after baclofen was discontinued. We discuss the pathogenesis and review the literature about baclofen-induced encephalopathies.

There are widely recognized unusual remote neurological manifestations of internal malignancy. However, as far as the author's knowledge, the generalized myokymia associated with myokymic discharge has not been reported as paraneoplastic syndrome earlier. The patient was a 63-year-old female with generalized myokymia and paresthesia for 4months. The nerve conduction study revealed mild sensorimotor polyneuropathy and EMG study showed the generalized myokymic discharges, which were not changed by sleeping or brachial plexus block. The carbamazepine reduced the amount of myokymia and myokymic discharges but not the benzodiazepine. The diagnosis of lung cancer was confirmed by needle aspiration biopsy, and the cell types of lung cancer were mixed undifferentiated and small cell type. By the administration of anti-cancer drugs including cisplatin, the myokymia and myokymic discharges were completely disappeared. The patient died at 8 months after the diagnosis.

Sulpiride, a selective antagonist for adenylate cyclase-independent dopamine receptors, was administrated to 25 patients with blepharospasm and oromandibular dystonia(Meige's syndrome). Of the 25, 7 patients (28%) exhibited marked and lasting improvement with sulpiride and 12 patients (48%) showed mild or transient improvement. This favorable therapeutic response to sulpiride suggests that striatal glutamate underactivity may play a role in the pathophysiology of Meige's syndrome as a primary or secondary defect.
