PURPOSE: To experimentally investigate the effect for muscle weakness after superior rectus Z-myotomy and histological changes. METHODS: Superior rectus muscle fibers of rabbits (16 rabbits, 32 eyes) were cut transversely with scissors across 75% of the muscle in two different positions on opposite sides. In group 1 (16 eyes), myotomies were performed at 2 and 7 mm from the muscle insertion (5 mm gap) and in group 2, performed at 2 and 5 mm (3 mm gap). The change of mark, eyeball position, and muscle tension after myotomy and 4 weeks postoperatively was evaluated, the location of the mark was examined, and muscle tissue biopsy was performed. RESULTS: After Z-myotomy, the marks of the two groups moved significantly posteriorly from insertion within groups (p<0.05), with no significant differences between groups (p=0.469). Eyeball positions of the two groups moved significantly inferiorly (p<0.05); the amount of position change of group 1 was greater than group 2 (p<0.05). When the globe was pulled in opposite directions for muscle action, the degree of change decreased with significant difference within groups (p<0.05), but there were no significant differences between groups (p=0.32). CONCLUSIONS: Z-myotomy of the superior rectus muscle affected the recession of eyeball position and weakened the muscle action. Muscle weakening affected by the different gaps between myotomies did not show consistent results.

2.Correlation Analysis of KT 2000 arthrometer, Cybex Isokinetic Test and Lysholm Knee Score in ACL deficient knees.
Journal of the Korean Knee Society 2002;14(2):173-179
PURPOSE: The authors performed correlation analysis among the values of KT 2000 arthrometer, Cybex isokinetic test, and Lysholm knee score to reveal the clinical significance and their role in functional evaluation of ACL insufficiency. MATERIALS AND METHODS: Fifty-one patients with isolated ACL insufficiency were evaluated with KT 2000 arthrometer (15, 20, 30 lb, max.manual), Cybex isokinetic test (60 & 180 degrees/sec), and Lysholm knee score. Correlation analysis was performed between the values of the tests. RESULTS: The Lysholm knee scores had significant linear correlation with the values of KT 2000 of maximal manual difference (r=0.587, P<0.05). The Lysholm knee score had significant linear correlation with all the values of Cybex test of hamstring & quadriceps muscle weakness (r=0.585, 0.635, 0.656, 0.720, p<0.05). The degree of muscle weakness and maximum manual difference in KT 2000 did not show any linear correlation. The time lap between injury and evaluation did not show any correlation with any of the above parameters. CONCLUSION: Lysholm knee score appears to be mostly influenced by the degree of muscle weakness than anterior displacement. The values of KT 2000 of maximal manual difference revealed to be best correlated with Lysholm knee score. The time interval after injury cannot be clinically correlated with muscle weakness or Lysholm knee score.

The authors have experience of a case of prolonged paresis following administration of galamine triethiodide to a patient undergoing reoperation. The muscular weakness continued for 20 hours, necessitating artificial ventilation intermittently. It was reversed by neostigmine.

7.The Purport of Steroid Treatment in the Weakness Phase of Parsonage-Turner Syndrome.
The Journal of the Korean Orthopaedic Association 2012;47(4):311-315
This article presents six cases of Parsonage-Turner syndrome with corticosteroid therapy in the muscle weakness phase. Three cases did not receive injected steroids after the onset of muscle weakness, and were classified as Group 1. The other three cases received injected steroid from just after muscle weakness onset, and were classified as Group 2. This article has a small study group of six cases, but is the first case study about the efficacy of steroids in the muscle weakness phase, showing a better treatment result when steroids were injected during the muscle weakness period. We report these findings, together with a review of the literature.

OBJECTIVE: To investigate the efficacy of core strengthening on trunk balance in patients with subacute stroke. METHOD: Fifty-nine subacute hemiparetic stroke in-patients participated in this study. All patients were randomly assigned to one of two groups: the control group and the experimental group. Both groups received the same conventional physical therapies for 4 weeks. The experimental group received an additional core strengthening program (CSP). Korean mini-mental state examination (K-MMSE) and Korean Modified Barthel Index (K-MBI) were performed on admission. CSP was performed for 30 minutes a day, 3 days per week for 4 weeks. We selected nine exercises available for stroke patients, and divided them as three steps according to the degree of difficulty. Because of the muscle weakness in stroke patients, a physical therapist often helped them during exercise. Outcome measurement included trunk control test (TCT), trunk impairment scale (TIS), and Berg balance scale (BBS) and we compared both groups before and after the period of training. RESULTS: There were no significant differences in baseline general characteristics and initial values between the two groups. After rehabilitation therapy, both groups showed significant improvements in BBS, TIS, and TCT (p<0.05). Following 4 weeks of therapy, changes of BBS, TIS score in the experimental group were significantly higher than those of the control group (p<0.05). However, the change of TCT score was not significantly different. CONCLUSION: Analysis of different clinical parameters showed that better outcomes in BBS, TIS scores were achieved from CSP. This study suggests that CSP conducted for 4 weeks may be beneficial as a therapeutic technique for use in improvement of trunk balance in patients with subacute hemiparetic stroke.

Partial or complete loss of innervation of skeletal muscle leads to muscle weakness and atrophic changes, resulting in decreased muscle volume with fatty replacement. Rarely, enlargement of the affected muscle may occur, related to two processes: true hypertrophy and pseudohypertrophy. We report CT and MR findings of the pseudohypertrophy of calf muscles, especially the soleus and gastrocnemius muscles, in a patient with diabetic neuropathy that showed increased muscle volume with diffuse fatty replacement and the presence of scanty muscle fibers.

Myotonia dystrophica or myotonia atrophica is inheritant disease which appears usually from 2nd or 3rd decade. This disorder is characterized by an impaired ability to relax a previously contracted muscle, muscle weakness and atrophy, cataract and multiple system involvement including the endocrines. The electrophysiological characteristics of myotonia dystrophica show a essential, differential features from the other myotonias with myopathic EMG changes. This paper describes 3 siblings with myotonia dystrophica and a case with no members of families clinically affected, and they were studied by clinically and by electromyographically.
