  • Purpose: This study aims to examine the functional difference in the long and short heads of the biceps brachii by investigating the onset time of muscle contractions in the biceps brachii in the supination motion according to whether the flexor of the elbow joint is excluded. Methods: This study was conducted with 21 healthy men aged in their 20s. While performing forearm pronation at an elbow flexion angle of 90 degrees, the onset time of muscle contractions in the long and short heads of the biceps brachii was measured and compared in a posture where the humerus is placed on a table and the posture is lifted against gravity. Using an independent samples t-test, the difference in the onset time of muscle contractions in the long and short heads of the biceps brachii was analyzed. Results: The onset time of the long head was shorter if the flexor activity of the elbow joint was excluded, while that of the short head of the biceps brachii was shorter if it was not excluded. Conclusion: It is noted that the long head of the biceps brachii mainly functions as a supinator muscle, while the short head of the biceps brachii plays a role in stabilizing and maintaining flexion of the elbow joint.

  • 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.

  • PURPOSE: This study was to investigate the effect of applying neck flexion during elbow flexion exercise on muscle activity of the biceps brachii, the anterior deltoid and the sternocleidomastoid (SCM). METHODS: Twenty healthy adults participated in this study. The subjects measured %MVIC (Maximal volumetric control) and collected the maximum electromyography (EMG) values in the biceps brachii, anterior deltoid, SCM. The first action was to sit in a sitting position with the eyes facing front and maintained the weight of each section by performing elbow flexion using a tension gauge. The second action was to sit in a sitting position with the head down and maintained the weight of each section by performing elbow flexion using a tension gauge. Paired T-test was used for comparison of the before-and-after neck flexion to analyze the muscle activity of the Biceps brachii of next flexion and extension, the SCM, and the Anterior deltoid during elbow flexion exercise. The Repeated measured ANOVA was used for comparing %MVIC in each muscle. The significance level (?) was set at .05. RESULTS: Neck flexion during elbow flexion increased the muscle activity of the Biceps brachii and Anterior Deltoid muscle in the maximal muscle strength 50 ~ 60%, 70 ~ 80% and decreased the muscle activity of the SCM (p < .05). CONCLUSION: The applic has been confirmed to reduce the mobilization of the SCM and increase the mobilization of the Biceps brachii and Anterior Deltoid to increase the mobilization. Therefore, it seems effective to apply neck flexion when elbow flexion exercise.

  • Muscle tone (stiffness/hardness) or muscle compliance changes during muscle contraction. The purposes of this study were to assess the intrarater and interrater reliabilities of the Myotonometer$^{(R)}$, electronic device that quantifies muscle tone. Two raters used the Myotonometer to assess the right bicep brachia and quadriceps muscles of 30 voluntary persons without any orthopedic or neurological problems (age range, 18~21 yrs). Muscles were measured in a relaxed state and during brief sustained voluntary maximal isometric contraction. Intrarater correlation coefficients were calculated for each muscle and for each condition (relaxed and contracted). Intrarater reliabilities (intraclass correlation coefficients, ICCs) ranged from .778 to .954, relaxed, biceps brachia), .926 to .963 (contracted, biceps brachia), .935 to .990 (relaxed, quadriceps) and .679 to .952(contracted, quadriceps). Interrater reliabilities ranged from .652 to .790 (relaxed, biceps brachii), .813 to .907 (contracted, biceps brachii), .831 to .950 (relaxed, quadriceps) and .849 to .937 (contracted, quadriceps). Myotonometer measurements had high to very high intrarater and interrater reliability for measurements of the biceps brachia and quadriceps muscles.
