The purpose of this study was to examine the convergence correlation between physical characteristics and functional movement screen(FMS). Overall, 193 adults with normal single measurement values participated in the study. For data analysis, we used the SPSS Ver. 26.0 statistical program to perform t-tests and to determine Pearson's correlation coefficients for variables. Data analysis revealed significant sex differences in the active straight-leg raise and trunk stability push up tests (P<.05). In addition, our data analysis also revealed a negatively correlation between body fat percentage and FMS tests, except in the shoulder mobility and active straight leg raise test. In the active straight leg raise, the quality of functional movement was higher in women than in men; while in the trunk stability push ups, the quality of functional movement was higher in men than in women. Therefore, we conclude that men should reinforce the flexibility of the lower extremities, and females should apply upper body muscular strength for better trunk stability movement.

Purpose : The purpose of this study is to investigate the effect of strengthening program for improving the muscle strength and body function in rehabilitation of patients with stroke Methods : We found the 15 precedent studies at online portal site of "Korea education and Research information service" and found 5 precedent studies at "Pubmed". We analyzed and describe the total 19 studies involving national and international research. Results : The strengthening exercise was adapted to lower extremities and trunk muscle of participants and the isokinetic (concentric and eccentric) exercise was most of exercise type and then manual isometric exercise, functional activities, progressive task oriented resistance exercise, PNF pattern exercise was following. The studies reported that the strengthening program increased target muscle strength and improved balance capacity and walking function for the participants positively. Conclusion : Conclusionally the several strengthening program can be the intervention to increase the muscle strength without increasing spasticity for patients with stroke. We think that the strengthening of lower extremities an improve balance capacity and walking ability and it can use the intervention to change the quality of life in patients with stroke. More than 3weeks strength program might be effectiveness, in case of acute patients with stroke, the improving of muscle strength is available but need to study for improving balance and walking capacity more in the future.

Achondroplasia is one of the most common types of dwarfism and is inherited as an autosomal dominant trait. Clinical features of achondroplasia include disproportionate short stature with normal trunk length, shortening of the extremities, bowing of the lower extremities, short stubby trident hands, spinal stenosis and lumbar lordosis. Characteristic craniofacial features include macrocephaly, prominent forehead, depressed nasal bridge, maxillary hypoplasia, otolaryngeal system dysfunction, and foramen magnum stenosis. These characteristics may lead to number of complications including hydrocephalus, apnea, upper-airway obstruction, otitis media, sinusitis and dental malocclusion. Apart from these features, the affected children have good general health and normal intelligence. Dentists should be aware of the clinical characteristics of achondroplasia and the complications that may arise as a result of this disorder. This case report is to present dental treatment of a patient with achondroplasia under general anesthesia and discuss special considerations.

A clinical analysis was made of 42 pilomatricoma in 34 children treated, from January 1980 to August 1996 at the Department of Pediatric Surgery, Hanyang University. The gender ratio was 13 to 21 with female preponderance. The average age at presentation was 7 years 3 months(range 8 months to 19 years old). The time average interval from onset to excision was 9.8 months. The predilection site was neck, upper extremities, face, trunk and lower extremities in the decreasing order of frequency. The masses were less than 3cm in diameter and there was no correlation between age at presentation and size of the mass. Of the six children with multiple lesions, two presented with multiple lesions initially and four presented with second lesion metachronously after excision of the primary lesions. Two girls had cysticercosis and von Recklinghausen's disease respectively in association with a pilomatricoma. All lesions were encapsulated subcutaneous masses which were clearly distinguished from surrounding tissue, and 4 of them had pigmentation, ulceration, skin disruption and hemorrhagic changes in the overlying skin. Microscopically the mass was composed of basophilic cells and eosinophilic shadow cells. Calcification, foreign body giant cell, ossification, focal cystic, inflammatory or necrotic changes were also seen.

Purpose: The recent development of MR has made to possible radiological diagnosis in various soft tssue tumors. But multifarious components within soft tissue tumors and their periodic change have made to difficult even differentiation of malignant from benign soft tissue tumors solely on the MR. So authors retry to differentiate malignant from benign soft tissue tumors with clinical and MR finding complex. Materials and methods: We were analysed 82 pathologically confirmed soft tissue solid tumors (37 cases as malignancy including intermediate tumors and 45 cases as benign including inflammatory masses) which are correlated with clinical findings such as age, size, and location, MR findings such as tumor border, texture on T2 and contrast-T1 images, and enhancement area retrospectively. Many typical lipoma and cysts including of ganglion and abscess are rejected in the benign soft tissue tumor group because not difficult to diagnose on MR. Results: Malignant soft tissue tumors were more frequent in 21~40 and 61~80 years old of the age, above 3.0 cm of the size, trunk-pelvis-lower extremities of the location, and MR findings with irregular border and above 50% of the enhancement area than those of benign soft tissue tumors. Conclusion: The clinical finding that divided to two locations as trunk-pelvis-lower extremities and upper extremities-shoulder-spine was statistically significant to differentiate malignant from benign soft tissue solid tumors. However, the others would provide some useful informations to differentiate them never specific.

A case of a symptomatic spinal extradural meningeal cyst (SEMC) in Klippel-Trenaunay syndrome (KTS) is introduced. A 38-year-old woman presented with right L2 radiculopathy. She underwent operations for varicose veins in both her lower extremities. She had port-wine nevi on her trunk and extremities. The edematous change in both legs had waxed and waned. Magnetic resonance imaging showed an $11.8{\times}13$ mm extradural meningeal cyst growing through the intervertebral foramen in L2-3. Multiple meningeal cysts were located in the dorsal aspect of the spinal cord from T3 to T10. A $5.8{\times}6.2$ mm cyst was also found in left pleural cavity. The extradural meningeal cyst was completely excised and the preoperative symptom was improved. KTS is a congenital disorder due to a mesodermal abnormality, which may predispose the dura to weakness. The SEMC may occur through the dural defect or weakened point.

The purpose of this study was to investigate the difference in the number of repetitions and the change in electromyographic response during the maximum speed squat exercise according to the depth conditions and the maximum speed squat exercise according to the time of each depth. Ten men in their 20s were selected as subjects and the maximum speed squat was performed for one minute in three environmental conditions (ground, knee depth, waist depth). We found that the number of repetitions according to the depth of water showed a significant difference, and as a result of the post-mortem comparison, the number of repetitions was higher in the ground condition and the knee depth than in the waist depth. And the muscle activity of rectus abdominis, erector spinae, rectus femoris, biceps femoris was increased during ground squat exercise, activity of all muscle was decreased during knee depth squat exercise, and activity of rectus abdominis, erector spinae, biceps femoris, tibialis anterior, gastrocnemius was decreased during waist depth squat. In conclusion, muscle activity of lower extremities during squat exercise in underwater environment can be lowered as the depth of water is deep due to buoyancy, but muscle activity of trunk muscles can be increased rather due to the effect of viscosity and drag.

Objective: The purpose of this study was to compare the effects of performing squats and kneeling squats on trunk and lower extremity muscle activity in persons with stroke. Design: Cross-sectional study. Methods: Ten persons with stroke (3 male and 7 female) were recruited. The subjects were instructed to randomly perform the 4 different squat conditions: squat with 30 degrees of knee flexion, squat with 60 degrees of knee flexion, squat with 90 degree of knee flexion, and the kneeling squat. During the squat performance, surface electromyograms (sEMG) was used to assess muscle activity of the erector spinae (ES), gluteus maximus (Gmax), gluteus medius (Gmed), and biceps femoris (BF) muscles. Results: Muscle activation of the ES and BF were significantly increased with the kneeling squats compared to the general squats with 30 degrees and 60 degrees of knee flexion (p<0.05), and muscle activation of the Gmax and Gmed were significantly increased with the kneeling squats compared to all other squat conditions (p<0.05). Conclusions: The results suggest that the kneeling squat is an effective exercise to strengthen the proximal muscles of the lower extremities. Rather than applying a difficult general squat to the stroke population, the kneeling squat may be applied as a safer method for training the proximal muscles.

Purpose: The aim of this study was to examine the activation of the contralateral upper and lower extremities and trunk muscle during ipsilateral upper extremity diagonal isokinetic exercise. Methods: Twenty-one healthy male subjects with no history of shoulder injury undertook ipsilateral diagonal isokinetic exercise at 60, 120, and $180^{\circ}/sec$, utilizing a standard Biodex protocol. Muscle activation amplitudes were measured in the upper trapezius, pectoralis major, biceps brachii, rectus abdominis, external oblique, rectus femoris, adductor longus, and biceps femoris muscles using electromyography. A one-way analysis of variance and paired t-tests were conducted, and the data were analyzed using SPSS, version 21.0. Results: The results revealed no statistically significant interaction between motion and angular velocity and no statistically significant contralateral muscle activation according to angular velocity (p>0.05). However, they revealed statistically significant contralateral muscle activation according to motion (p<0.05). Conclusion: These results suggest that the movements involved in contralateral upper extremity diagonal isokinetic exercise can enhance muscle strength in patients affected by stroke, fracture, burns, or arthritis.
