Purpose : Bridging exercise was used most frequently of lumbar stabilization exercise. There has been no reserch regarding the bridging exercise according to hip abductor activation or hip adductor activation. The purpose of this study is to determine correlation of hip abductor, adductor and abdominal muscles, lower limb muscle. Methods : Participants who met the criteria for this study (n=45). Participants performs bridging exercise on three types (normal bridging exercise, bridging exercise with hip abductor contraction, bridging exercise with hip adductor contraction) for evaluate correlation of each muscles. Results : There was a significant negative correlation between adductor magnus and gluteus medius, adductor magnus and rectus femoris. And there was a positive correlation between gluteus medius and rectus femoris on normal bridging exercise (p<0.05). There was a significant positive correlation between adductor magnus and gluteus medius, transverse abdominis, and between gulteus medius and transverse abdominis on bridging exercise with adductor magnus activation (p<0.05). There was a significant positive correlation between adductor magnus and gluteus medius, rectus femoris, and between gulteus medius and rectus femoris on bridging exercise with gluteus medius activation (p<0.05). Conclusion : When we perform bridging exercise for transverse abdominis activation and increase pressure in the abdmen, bridging exercise with hip adductor contraction is more effective than normal bridging exercise and bridging exercise with hip abductor contraction.

Purpose :The present study invesigated the effect of changes in transversus abdominis thickness using ultrasonography during a hip adductor contraction. Methods : This study was carred out in a volunteer sample of adults (N=30) without a history of low back pain or injury. In standing position, muscle thickness measurements of transversus abdominis(TrA) were measured using ultrasonography at rest and during a hip adducor contraction. Results : TrA thickness were influenced a hip adductor during a voluntary contraction in people without LBP. TrA showed significantly greater thickness changes on a hip adductor contraction.(p=0.000) Conclusion : The results from this study showed that the hip adductor contraction improves the ability to increase change in TrA thickness. These results can be a good evidence to prevent low back pain due to hip adductor weakness or genu varum deformity of knee osteoarthritis.

Purpose: Authors analyzed and compared the treatment result of distal chevron osteotomy between with and without adductor tenotomy. Materials and Methods: 36 patients (60 feet) with a minimum follow-up of one year were involved in this retrospective study. The chevron osteotomy without adductor tenotomy was performed for 20 patients (30 feet) and chevron osteotomy with adductor tenotomy was done for 16 patients (30 feet). The first metatarsophalangeal (MTP) angle and angle between first and second metatarsal longitudinal axis (IM) was measured. The difference of these angles were measured pre-and postoperatively and compared using Student's T-test. Results: In the group of chevron osteotomy with adductor tenotomy, the mean first MTP angle corrected $29^{\circ}$ pre-operatively to $9^{\circ}$ and the mean first IM angle corrected $16^{\circ}$ pre-operatively to $12^{\circ}$. In the group of chevron osteotomy without adductor tenotomy the mean first MTP angle corrected $31^{\circ}$ pre-operatively to $11^{\circ}$ (P>0.05) and the mean first IM angle corrected $13^{\circ}$ pre-operatively to $11^{\circ}$ (P>0.05). Deep peroneal neuroma were found in 3 cases of chevron osteotomy with adductor tenotomy. Conclusions: Adductor tenotomy should be performed in selected patient with chevron osteotomy to prevent deep peroneal neuroma.

Purpose: This study was to investigate the differences abdominal muscles activities of according to hip adductor contraction levels 20% (mild), 50% (moderate), and 70% (strong) of MVIC on during bilateral lower extremity raising exercise on supine. Methods: The subjects of the study were a total of 39 persons including 23 healthy males and 16 females, who performed bilateral lower extremity raising exercise in 20%, 50%, 70% MVIC hip contraction. Muscle activities were measured by using S-EMG in RA (rectus abdominis), IO (internal oblique), and EO (external oblique). Results: Muscle activity of the internal oblique abdominal muscle and external oblique abdominal muscle, their activities were also greatest with the adductor contraction size at 70% and there was statistically significant difference when compared with the adductor contraction size at 20% and 50% (p<0.05). As for the rectus abdominis muscle according to the size of contraction of the adductor was greatest at 70%, without statistically significant difference (p>0.05). Conclusion: bilateral lower extremity raising with strong hip joint adductor contraction was effective exercise to strengthen abdominal muscles. If subjects could not perform strong hip adductor contraction, moderate contraction is effective abdominal muscle contraction exercise. The contraction size of the adductor is small, weak contraction may trigger middle level contraction and therefore appropriate application of the exercise program of bilateral leg raising may result in great effect as a lumbar stabilization exercise.

PURPOSE: The purpose of this study was to determine the correlation between the hip adductor muscles and abdominal muscles during bridge exercise. METHOD: Participants who met the criteria for this study(n=36) were divided into the three groups. The first experimental group performed normal bridge exercises and the second group performed bridge exercises with the contraction of the hip adductor muscles and the control group didn't perform any exercise. Transversus abdominis muscle thickness was measured by ultrasound imaging with a special transducer head device, at pre exercise, after 2 weeks, 4 weeks, and 6 weeks. RESULT: Data were analyzed using repeated ANOVA with the level of significance set at ${\alpha}=.05$. Transversus abdominis muscle thickness was influenced by contraction of the hip adductor muscles during bridge exercise in people without lower back pain. Compared with normal bridge exercise, transversus abdominis muscle thickness significantly increased in thickness during bridge exercise with contraction of the hip adductor muscles(p<.05). CONCLUSION: The results from this study showed that contraction of the hip adductor muscles during bridge exercise increased change in the transversus abdominis muscle thickness. These results can be a good source to prevent low back pain due to hip adductor weakness. Therefore, inducing activation of hip adductor with abdominal stabilizing exercise is more effective in patients with low back pain.

We inestigated the reproductive cycle with ovarian development of Chlamys farreri by histological observations, and seasonal changes in biochemical components of the adductor muscle, digestive diverticula and ovary were studied by biochemical analysis. The reproductive cycle of this species can be classified into five successive stages: early active stage (January to March), late active stage (March to April), ripe stage (April to August), partially spawned stage (June to August) and spent/inactive stage (August to January). According to ANOVA test, there were significant differences (p<0.05) in total protein, total lipid and glycogen contents among months for all of the adductor muscle, digestive diverticula and ovary. Total protein contents in ovary and digestive diverticula showed significant changes(ANOVA, p<0.05) during the study period, while that in the adductor muscle did not. Total protein content was highest in the adductor muscle, followed by ovary, and lowest in digestive diverticula. There was no correlation in total protein content between the adductor muscle and digestive diverticula (p=0.220). But strong positive correlation was found between adductor muscle and ovary (r=0.450, p=0.013). ANOVA showed that there were significant differences in total lipid and glycogen contents among months for all of the adductor muscle, ovary, and digestive diverticula (p<0.05). The monthly changes in total lipid content were highly variable in ovary and digestive gland. High contents of total lipid were foung during April and May-June in ovary, while March and June-July in digestive diverticula. There was a strong negative correlation in total lipid content between ovary and digestive diverticula (r=- 0.397, p=0.030). Unlike total protein of total lipid, glycogen content in the adductor muscle was most dynamic. It showed more than 36-fold changes in the adductor muscle (at most 3-fold change in ovary) during the study period. Glycogen content was higher during May-July in the adductor muscle, While it was higher in March and august in digestive diverticula. There was a strong negative correlation in glycogen content between the adductor muscle and digestive diverticula (r=-0.584, p=0.001).

PURPOSE: This study examined the changes in the thickness of the abdominal muscles, including the transversus abdominis, according to the set pressure applied by a pressure biofeedback unit during contractions of the hip adductor muscles. METHODS: After randomizing 40 healthy adult males in their 20 s and 30 s, the participants were instructed to match the pressure gauge indication of the pressure biofeedback device to continue contracting the hip adductor while maintaining it at 10 mmHg (low), 40 mmHg (medium), or 70 mmHg (high). The measurement was taken over five seconds using an ultrasound device. RESULTS: According to the contractile pressure applied to the hip adductor muscle, there was a significant difference in the muscle thickness change of the transverse abdominis muscle between 10 mmHg and 70 mmHg and between 40 mmHg and 70 mmHg. The muscle thickness ratio of the external oblique/abdominal muscle was significantly different between 10 mmHg and 70 mmHg and between 40 mmHg and 70 mmHg. CONCLUSION: Increased contraction pressure on the hip adductor muscle increases the muscle thickness of the abdominal transverse muscle. Interbody stability exercise with contractions of the hip adductor muscle is expected to help increase in the muscle thickness of the hip adductor muscle.

The purpose of this study is to show the aerodynamic characteristics and differences in muscle tension dysphonia and adductor spasmodic dysphonia to predict factors which will provide additional information while preparing for the objective examination standard to distinguish the two dysphonias. Forty-eight individuals diagnosed with muscle tension dysphonia and adductor spasmodic dysphonia participated in this study. PAS was used in order to find the aerodynamic characteristics for the two dysphonias. The outcomes of this study show that the airflow variation and glottal resistance of the two groups showed noticeable differences. This study concludes that the aerodynamic characteristics may be used as additional information on diverse evaluations to classify muscle tension dysphonia and adductor spasmodic dysphonia.

The author have studied the relationship between the maximum puberal growth stage in body height and the appearance of the adductor sesamoid of the thumb with wrist x-ray films. In addition to this, it has been investigated the age at which pubic hair appeared in boys, and the age at menarche in girls. The results were as follows: 1) The ossification of the adductor sesamoid of the thumb occured at 13-years-o-month in boys and 10-years-8-months in girls. 2) There was a close association between the age at maximum puberal growth in body height and the age when ossification of the adductor sesamoid of the thumb occured, and also in girls, the age at the menarche. 3) Appearance of the adductor sesamoid of the thumb indicated that maximum puberal growth in body height is imminent or has been reached. 4) The maximum puberal growth in body height occured 23 months earlier in girls than in boys, and ossification of the adductor sesamoid of the thumb 28 months earlier in girls. 5) Appearance of the pubic hair in boys was of no value for prediction of maximum puberal growth in body height. 6) Menarche is a reliable indication that the maximum puberal growth in body height has been reached or passed.
