  • Experiments have been performed for estimating the individual muscle capabilities of the biceps brachii and the quadriceps femoris muscle. The surface EMG has been recorded on the bellies of the biceps brachii and the quadriceps femoris muscle during isometric contractions at $50\%,\;75\%,\;and\;100\%$ MVC. The rectified EMG amplitudes of the maximum voluntary contraction (MVC) were in the range of $2.8\~3.0\;mV\;and\;6.9\~7.2\;mV$ the biceps brachii and the quadriceps femoris, respectively. In the biceps brachii, Type S motor units were recruited in the range of $41\~49\%$ MVC; and Type F motor units were recruited in the range of $51\~59\%$ MVC, In the quadriceps femoris, Type S, Type SF, and Type F motor units were recruited in the ranges of $31\~38\%,\;33\~48\%$, and $21\~29\%$ MVC respectively.

  • A ganglion is a benign cystic mass, commonly found around a joint or tendon sheath. It frequently occurs at the wrist, foot, ankle, and knee. Intratendinous ganglion has been rarely reported, and intratendinous ganglion of the long head of biceps brachii is extremely rare. According to our literature review, this is the third case of intratendinous ganglion of the long head of biceps brachii, and the first case of arthroscopic treatment. Therefore we report a case of an arthroscopic treatement for an intratendinous ganglion of the long head of biceps brachii.

  • In general, the long head of the biceps brachii originates from the superior glenoid labrum and the supraglenoid tubercle, crosses the rotator cuff interval, and extends into the bicipital groove. However, rare anatomic variations of the origins of the long head have been reported in the past. In this report, we review the clinical history, radiologic findings, and arthroscopic identifications of 3 anatomic variants of the biceps tendon long head. As the detection of long head of biceps tendon pathology during preoperative radiologic assessment can be difficult without prior knowledge, surgeons should be aware of such possible anatomic variations.

  • Background: The purpose of our experimental study, we want to know a correlation study using the sonogram between the muscle strength and the diameter of Biceps brachii muscle by gender. So we set to hypothesis that Biceps brachii contracted maximally would be a diameter of the muscles increased according to the muscle strength will be increased. Methods: In this study, we measured the muscle strength of biceps brachii on contracting its maximum using the Biodex and the diameter of the muscles using Myo-Lab (25Gold). We experimented 30 subjects of twenty-aged men and women. The subjects is comprised of a persons who has not external injuries and pain of elbow joint, no mobility limitation of ROM, no experiences of surgery in past history. Result: We found that the men have a highly correlation between maximum strength and the diameter of the muscles more than women (p<.05). Conclusion: The results of our experimental study between the muscle diameter and the muscle strength to biceps brachii on relaxation and contraction is a statistically significant relation (r=.394), especially in rather men then women (p<.05). So this results would be based data for further clinical muscle efficiency application in physical therapy field.

  • Background: Sonoelastography (SE) is a new technique that can assess differences in tissue stiffness, the purpose of this study was to evaluate the ability of SE to assess the long head of biceps tendon alteration. Methods: Forty shoulders of 36 consecutively registered patients with clinical symptoms and conventional ultrasonography findings of biceps tendinitis or tendinosis, and 40 asymptomatic shoulders of 20 healthy volunteers were assessed with SE. Transverse and longitudinal images of long head of biceps tendon were obtained using SE. SE images were performed by one orthopedic surgeon and evaluated by two orthopedic surgeons using an experimentally proven color grading system. Results: The transverse images of SE showed a sensitivity of 87.5%, a specificity of 95.0% and a accuracy of 91.3%, the longitudinal images of SE showed a sensitivity of 92.5%, a specificity of 90.0% and a accuracy of 91.3%. Inter-observer reliability of SE was in 'almost perfect agreement' with a weighted kappa coefficient of 0.83. Conclusions: SE is valuable in the detection of the intratendinous and peritendinous alterations of biceps tendon, and has excellent accuracy and excellent correlation with conventional ultrasound findings.

  • 다양한 이두근 건고정술이 시행되고 있어서, 문헌들의 결과를 단순 비교하기 어렵게 만든다. 이두근 장두의 건고정술은 첫째로, 시술을 관혈적 절개를 통하여 시행하는가 또는 관절경을 이용한 방법으로 시행하는가로 구분해 볼 수 있다. 두 번째로는, 이두건 자체를 고정하는 주변 조직에 따라서 연부 조직 건고정술과 골 고정술로 나눌 수 있다. 세 번째로는, 고정하는 위치에 따라 근위부와 원위부로 구분할 수 있다. 네 번째로는, 건 고정술에 기구(간섭 나사, 봉합 나사, 비매듭 봉합 나사 등)를 사용하는 가에 따라서 구분해 볼 수 있다. 적절한 고정력이 어느 정도인지 밝혀지기까지는 단정적인 결론은 보류되어야 한다.

  • Biceps tendon dislocation combined with rupture of subscapularis tendon is not a common lesion and there has been few case reported in Korea. We experienced one fifty Six years old male patient who shows typical features on physical examination and roentgenographic finding. He was injured by direct trauma on his right shoulder in adducted and external rotated position. He showed positive findings on passive external rotation test and lift-off test. On MR!, the subscpaularis tendon was totally ruptured and the biceps tendon was dislocated to anteromedial aspect of the glenoid labrum, which was typical finding. On the arthroscopic examination, the subscapularis tendon was totally ruptured from its humeral attachment and the biceps tendon was not seen in its normal anatomical position and it was dislocated antermedially to the glenoid labrum. We repaired the subscapularis tendon to humerus by use of suture anchor and the biceps tendon was relocated to its normal anatomical position in the intertubercular groove. On the post operative 6 months follow up, the patient shows improvements in his subjective symptoms and active range of motion.

  • The purposes of this study were to analyze and compare EMG activities of the pectoralis major, biceps brachii, triceps brachii, and brachioradialis muscles during biceps curls using a VRT device and an elastic tubing. Fifteen male college students were recruited as subjects and they performed 10-RM and 20-RM biceps curls. For each load and device condition, the mean and peak normalized EMG levels during different phases of a biceps curl were computed. For each load and phase, paired t-test (p.05) was used to find the significant difference between two devices. ANOVA with repeated measures was also used to find the significant difference among phases in terms of EMG values for each muscle. For each load and device condition, the peak and mean EMG levels during different phases of a biceps curl were computed The significant differences between devices were found in biceps brachii for EA, MD, LD phases, and triceps brachii muscles for all phases, respectively. However, no differences were found among phases for any muscle. This indicated that elastic band could have a similar characteristics of VRT. High antagonistic muscle activity as a function of injury prevention which found particularly in VRT device may suggest that elastic tubing can be a safer training device than VRT. This also imply that elastic tubing could be very effective as a home exercise tool for rehabilitation patients and elderly people.
