Purpose : Bridge exercise has been commonly used in clinical rehabilitation settings to improve trunk control, and hip adductor muscles were a related muscle that may affect trunk muscle activation. The aim of this study was to investigate whether the co-contraction of hip adductor muscles may affect trunk muscle activation during bridge exercises. Methods : Thirty-eight healthy young subjects (19 men and 19 women) performed bridge exercises (with and without hip adduction movement). Surface electromyography (EMG) data were collected from the dominant-side internal oblique (IO), rectus abdominis (RA), multifidus (MF) and erect spine (ES) during bridge exercises to compare trunk muscles activation patterns. Result : The EMG activities of IO and RA appeared to be significantly higher during bridge exercise with hip adductor co-contraction than during bridge exercise alone (p<.01), but there were no significant differences in those of MF and ES. Furthermore, there were significant differences in the IO:RA EMG ratio during bridge exercise with hip adductor co-contraction (p<.05). Conclusion : These findings suggest that integration of hip adduction during bridge exercise may be beneficial in increasing deep muscles' activity for trunk stabilization.

Purpose : The clinical scale to assess spasticity of muscle was wildly used the modified Ashworth scale (MAS). But reliability of the MAS has been controverted for ambiguity among the grades. The purpose of this study was to establish the inter-rater reliability of the modified MAS (MMAS) translated into Korean in stroke patients. Methods : Twenty-five patients (sixteen men and nine women) with hemiplegia (ten right and fifteen left) were measured by two raters who were physical therapist in the rehabilitation hospital. The raters assessed spasticity of shoulder adductor, elbow flexor, wrist flexor, hip adductor, knee extensor, and ankle plantar flexor in the same patients according to ratings criteria of the MAS and the MMAS. Results : For the inter-rater reliability of the MAS, two raters agreed on 57.3% and the Kappa values were moderate ($\kappa$=0.41) between two rater. The inter-rater reliability of the MAS was fair for the wrist flexor and the hip adductor and moderate for the other muscles. The intra-rater reliability was good for the shoulder adductor and the knee extensor and moderate for the other muscles. For the inter-rater reliability of the MMAS, two raters agreed on 84.7% and the Kappa values were good ($\kappa$=0.78) between two rater. The inter-rater reliability of the MMAS was moderate for the hip adductor, and good for the shoulder adductor and the wrist flexor, and very good for the other muscles. The intra-rater reliability was good for the wrist flexor and the hip adductor and very good for the other muscles. Conclusion : This study suggests that the MMAS translated into Korean is reliable test scale for the spasticity with stroke patients in the clinical field.

Seasonal content changes of the three key nutrients for organisms, protein, lipid and glycogen, were analyzed for a whole year to delineate the seasonal energy strategy in pen shells, Atrina pectinata. Two metabolically important organs, the visceral mass and the posterior adductor muscle, were examined. Protein in the visceral mass rose in April and stayed at the level until June followed by the constant minimum value between August and November. The protein contents in the posterior adductor muscle increased sharply in April and again in July, followed by a gradual decline thereafter. Total lipid contents in the visceral mass gradually increased between January and May, and then slowly decreased until September since which a new weak increase was noticed. Lipid levels in the adductor muscle rapidly dropped in June and July. Glycogen contents in the visceral mass rapidly increased between February and June, followed by a drastic drop in July. This reduced visceral glycogen level was maintained up to September, and a gradual reduction ensued. Glycogen contents in the adductor muscle steadily but markedly increased from April reaching the maximum in August, and then slowly declined thereafter. These results suggest that an accelerated protein and lipid synthesis occurs in the gonad when the pen shell undergoes the ripe stage of gametogenesis, but the levels of these two nutrients decrease on spawning. With this gonadal process, regular protein synthesis and lipid storage in the posterior adductor muscle are temporarily arrested. The most important nutrient reserves that support gonad developmental cycles in a long term seem to be glycogen of the posterior adductor muscle.

Background: Delivery workers repeatedly get in and out of trucks and walk or run to deliver packages during work. Iliotibial band syndrome (ITBS) is a well-known non-traumatic overuse injury of the lateral side of the knee caused by frequent knee flexion and extension. Hip muscle strength is among the factors that prevent lower extremity injuries. Although many studies have examined the relationship between ITBS and hip muscle strengths, there was no study comparing hip muscle strength and ratio between delivery workers with and without ITBS. Objects: This study aimed to compare hip muscle strength and hip internal/external rotator and adductor/abductor strength ratios between delivery workers with and without ITBS. Methods: Fourteen delivery workers with ITBS matched inclusion criteria in the present study among 20 participants. Because total sample size was required 28 subjects by G*power program (ver. 3.1.9.4; University of Trier), 14 delivery workers without ITBS were recruited. Hip muscle strengths were measured in a side-lying position using a Smart KEMA pulling sensor (KOREATECH Co. Ltd.). An independent t-test was used to compare hip muscle strengths and hip internal/external rotator and hip adductor/abductor strength ratios between delivery workers with and without ITBS. Results: The adductor/abductor strength ratio was significantly greater in delivery workers without ITBS than in those with ITBS (p < 0.05). The strengths of the hip abductor, hip adductor, hip internal rotator, hip external rotator, and the ratio of internal/external rotator strengths were not significantly different between the delivery workers with and without ITBS (p > 0.05). Conclusion: This study's findings showed that delivery workers with ITBS had significantly lesser adductor/abductor strength ratio, while the strengths of the hip abductor and adductor muscles did not differ significantly. These results suggest that adductor/abductor strength ratio should be considered when evaluating and treating ITBS in delivery workers.

We investigated the reproductive cycle with gonadal development of the female Cyclina sinensis by histological observations and seasonal changes in biochemical components of the adductor muscle and visceral mass tissues were studied by biochemical analysis, from January to December, 2001. The reproductive cycle of this species can be classified into five successive stages: early active stage (February to April), late active stage (March to June), ripe stage (May to August), partially spawned stage (July to October) and spent/inactive stage (September to February). Total protein contents in the adductor muscle tissues reached the maximum in February (early active stage) and appeared the minimum in June (ripe stage), while their contents in the visceral mass tissues reached the maximum in the late active and ripe stages (June) and gradually decreased from July (partially spawned stage) to November (spent/inactive stage). Changes in total protein contents showed a negative correlationship between the adductor muscle and visceral mass tissues (r = -0.499, p = 0.099). Total lipid contents in the adductor muscle tissues reached the maximum in January (the inactive stages) and their contents gradually decreased from February. Their contents in the visceral mass tissues, however, reached the maximum in June (late active and ripe stage) and gradually decreased from July (the partially spawned stage). On the whole, total lipid contents showed a negative correlationship between the adductor muscle and visceral mass tissues (r = -0.631, p < 0.05). Therefore, These results indicate that the nutrient contents of the adductor muscle and visceral muscle tissues change in response to gonadal energy needs. Glycogen contents in the adductor muscle tissue reached the maximum in March (early and late active stages) and decreased from July to September (partially spawned stage). while their contents in the visceral mass tissues reached the maximum in June (late active and ripe stages) and gradually decreased from July (partially spawned stage). Thereafter, their levels gradually increased in November (spent/inactive stage). On the whole, changes in glycogen contents appeared negative correlationship between the adductor muscle and visceral mass tissues. However, they showed no significant different (r = -0.307, p = 0.331).

Spasmodic dysphonia is a voice disorder characterized by involuntary voice breaks during speech. Adductor spasmodic dysphonia is most common and characterized by strained and strangled voice breaks. The current standard of treatment of therapy for adductor spasmodic dysphonia is chemodenervation of thyroarytenoid muscle with botulinum toxin(Botox). However, Botox is a temporary treatment with each injection lasting approximately 3 months on average and require repeated injections. In this study, we report our experience with surgical treatment for adductor spasmodic dysphonia. In this procedure, the thyroarytenoid branch and lateral cricoarytenoid branch of recurrent laryngeal nerve is selectively denervated unilaterally, and its distal nerve stump of thyroarytenoid branch is reinnervated with branch of the usa cervicalis nerve. And lateral cricoarytenoid muscle partial myotomy was done unilaterally. After 6 months of treatment, voice fluency had improved and no period of breathiness or dysphagia was noted.

2003년 1월부터 12월까지 일본재첩의 생식소 발달단계에 따른 생식주기를 조직학적 관찰에 의해 조사하였고, 폐각근과 내장낭 및 족부 근육의 생화학적 성분의 계절적 변화를 조사하였다. 본 종의 생식주기는 초기활성기 (2-4월), 후기활성기 (4-7월), 완숙기 (6-8월), 부분산란기 (7-9월), 퇴화 및 비활성기 (9-3월) 의 연속적인 5 단계로 구분할 수 있었다. ANOVA test 결과, 내장낭 조직과 폐각근 및 족부 근육 모두에서 월 중 총단백질, 총 지질 및 글리코겐 함량들 사이에는 유의한 차이가 있었음을 나타내었다(p < 0.05). 총 단백질 함량은 폐각근 내에서 최대였으나 내장낭에서는 최소로 나타났다. 내장낭과 폐각근의 총단백질 함량은 아무런 상관관계를 보이지 않았으나 (p = 0.208), 폐각근과 족부 근육 사이에서는 강한 양의 상관관계 (r = 0.769, p < 0.001) 를 보였다. 총 지질 함량은 내장낭 내에서 가장 높았다. 그 함량은 폐각근 또는 족부 근육의 함량 보다 2, 3배 더 높았으며, 월별 변화도 내장낭 내에서 가장 크게 변하였다. 총지질 함량은 1월부터 3월까지 감소되었으나 4월에 증가 되어 최대를 이루었으며, 그 후 5월부터 8월까지 점차 감소된 다음 10월까지 다시 증가되었다. 다중비교 결과, 인접하고 있는 두 달 모두에서 내장낭 내 총지질 함량들 사이에는 유의한 차이를 보였다(p < 0.05). 내장낭과 폐각근 사이의 총지질 함량 간에는 강한 음의 상관관계 ( r = 0.678, p < 0.001) 를 나타내었고, 내장낭과 족부 근육 사이에도 음의 상관관계 (r = 0.473, p < 0.008) 를 보였다. 글리코겐 함량 변화는 4월을 제외하고, 내장낭, 폐각근 및 족부 근육 사이에 다소 유사하게 나타났다. 4월에 내장낭 내 글리코겐 함량은 폐각근이나 족부 근육내 함량들 보다 4배나 더 높았다. 폐각근과 족부 근육내의 글리코겐 함량 사이에는 양의 상관관계 (r = 0.686, p < 0.001) 를 보였다. 특히, 총 지질 함량은 폐각근과 내장낭 사이에 음의 상관관계를 보였다. 따라서 이들 결과는 폐각근과 내장낭의 영양물질 함량이 생식소의 에너지 요구에 반응하여 변하고 있음을 시사한다.

We investigated the insulin-like growth factor 1 (IGF-1)/AKT signaling pathway involved in muscle formation, growth, and movement in the adductor muscle of triploid Pacific oyster, Crassostrea gigas. Large and small triploid oysters (LTs and STs) cultured under identical conditions were screened, and the signaling pathways of individuals with superior growth were compared and analyzed. mRNA and protein expression levels of actin, troponin, tropomyosin, and myosin, proteins important in muscle formation, were higher in LTs compared with STs. Expression levels of IGF-1, IGF binding protein (IGFBP), and IGFBP complex acid-labile subunit were also higher in LTs compared with STs. Phosphorylation of the IGF receptor as well as that of AKT was high in LTs. In addition, the expression of phosphomammalian target of rapamycin and phospho-glycogen synthase kinase $3{\beta}$ was increased and the expression of Forkhead box O3 was decreased in LTs. Therefore, we suggested that the IGF-1/AKT signaling pathway affects the formation, growth, and movement of the adductor muscle in triploid oysters.

Background: This study aimed to identify exact anatomical landmarks and ideal injection volumes for safe adductor canal blocks (ACB). Methods: Fifty thighs from 25 embalmed adult Korean cadavers were used. The measurement baseline was the line connecting the anterior superior iliac spine (ASIS) to the midpoint of the patellar base. All target points were measured perpendicular to the baseline. The relevant cadaveric structures were observed using ultrasound (US) and confirmed in living individuals. US-guided dye injection was performed to determine the ideal volume. Results: The apex of the femoral triangle was 25.3 ± 2.2 cm distal to the ASIS on the baseline and 5.3 ± 1.0 cm perpendicular to that point. The midpoint of the superior border of the vasto-adductor membrane (VAM) was 27.4 ± 2.0 cm distal to the ASIS on the baseline and 5.0 ± 1.1 cm perpendicular to that point. The VAM had a trapezoidal shape and was connected as an aponeurosis between the medial edge of the vastus medialis muscle and lateral edge of the adductor magnus muscle. The nerve to the vastus medialis penetrated the muscle proximal to the superior border of the VAM in 70% of specimens. The VAM appeared on US as a hyperechoic area connecting the vastus medialis and adductor magnus muscles between the sartorius muscle and femoral artery. Conclusions: Confirming the crucial landmark, the VAM, is beneficial when performing ACB. It is advisable to insert the needle obliquely below the superior VAM border, and a 5 mL injection is considered sufficient.
