  • The purpose of this work is to investigate the fundamental properties of the gradual muscle force potentiation for the prediction of muscle force and body movement from the stimulation input with musculo-skeletal model. We investigated the dependence of force potentiation on both the pulse-amplitude and the pulse-duration. The experimental result showed that the force increment ratio during electrical stimulation decreased with pulse-amplitude. The force increment ratio decreased with short pulse-duration and was maintained to be constant with pulse-duration longer than $500{\mu}s$. A new model of the muscle potentiation based on these results is desired in the future.

  • The purpose of this study is to measure perceived joint discomfort in the seated and standing position, and to provide a ranking system of joint discomfort measured in this study. Seven male subjects with no history of musculo-skeletal disorders participated in the experiment. Their physical characteristics were: age -$27.6 {\pm}1.8$ years, stature -$171.0 {\pm}5.5cm$, and body weight -$66.4{\pm}9.3kg$. The results showed that perceived joint discomfort was different depending on the human body joints involved in motion and their movement directions, which imply that the human body motions should be classified intoseveral distinct classes that need to be assigned different weights of postural stress. In the seated postion, the hip movement was the most stressful, the back was the second, and the shoulder was the third. Similarly, in standing postures, the hip was given the highest ranking, followed by the back, and the wrist.

  • One of the major requirements in preventing Work-related MusculoSkeletal Disorders(WMSDs) is to know definitely what vigorous exertion requirements are contained in a job. This requires improved job analysis tools which can accurately evaluate potentially harmful stresses to the musculoskeletal system. But to simply evaluate the level of stress at a joint, or in a muscle is not enough to motivate job changes. Therefore, the development of ergonomic evaluation tools for the jobs are important to ergonomics. The main objective is compared of the results that made by the ergonomic evaluation tools (e.g., BRIEF and RULA) in actually shoes manufacturing. These were developed in the foreign. So, it is priory needed to research of the ergonomics about Korean characteristic work by physiology and biomechanics.

  • Ultrasound is a first line examination of the knee and useful diagnostic tool in assessing the various knee lesions. The advantages of ultrasound are that it is non-invasive, easily available at bed side, cheap, well accepted by patients, and that it has technical benefits including dynamic evaluation. Its limitations include reliability, which is largely operator dependent and its inability to evaluate deep structures. Technical guidelines of the ultrasound released by European Society of MusculoSkeletal Radiology (ESSR) and ultrasonographic findings of various knee lesions are described.

  • MET is one of the few physical therapy having its own criteria. Mr. Holten approached the Norwegian Health Authority in 1967 to get his MET System recognized as a treatment method of its own. He was granted his approval for his exercise system's specivic criteria connecteed with the treatment method. In MET, the patient exercises himself without manual participation by physiotherapists, however, under continuous supervision.. The apparatus should be designed that functional quality (arthrogenous, circulatory, respiratory, neuromuscular) in question is optimally influenced when the patient carries out exercise in a certain range against a graded resistance. The therapy reassesses the scheme of treatment at least every fifth session and the maximum number of patients being 5 person per hour. The important principles in medical exercise Therapy are stabilization of hyperfunction through the system of autostabilization and mobilization of hypofunction through automobilization. In MET excrcises are adjusted to the patient's reactions. MET equipment is therefore made to meet requirements for treating patients with painful pathological dysfunction in the musculo-skeletal system.

  • A whiplash injury of cervical spine is typically caused by a special kind of accident. It usually involves a driver of an automobile who experiences a direct impact from behind. There are no external signs of the injury, but shearing forces from the rapid flexion and extension momement result in segmental lesions. The extent of injury to the tissue depends upon the force of impact, the exact position of head at the moment of impact, the awareness of impending injury in order to "prepare" the musculature, and the normalcy of all the tissues of the neck. Diagnosis demend a carefully detailed history and a through musculo-skeletal--neurological examination. Whenever possible, the symptoms claimed must be verified by a carefule neurological examination.

  • Yak-ju treatment is regarded as a new way to give a medication, and used many parts of medical field such as musculo-skeletal, aesthetic and cosmetic part. Recently I've experienced a good result by Yak-ju treatment for managing obese patient who had failed to lose his weight by conventional existing treatments comprised of herbal medicine, electro-lypolysis, negative pressure, ear acupuncture, behavior modification therapy and education for diet and exercise. This method can be recommended as a new method for curing obesity that can make up for the weak point of existing ways.

  • The purpose of this study was to analyse the EMG activity of selected muscles with balance taping treatment and blood fatigue makers which accumulated during exercise of progressive maximal intensity. Ten male college students who did not experience any cardiovascular and musculo-skeletal disease were participated in this study. Balance taping were applied to rectus femoris, vastus medialis, vastus lateralis, biceps femoris, semitendinous, semimembranous, and around knee joint. Isokinetic knee joint flexion/extension force, EMG activity, lactate and ammonia as blood fatigue makers during progressive maximal intensity exercise were measured for with/without applying balance taping. The results indicated that although flexion force of total work at $60^{\circ}/sec$ with taping was increased applied taping did not affect to the aerobic exercise ability parameters. Lactate level as blood fatigue makers during progressive maximal intensity exercise after taping was decreased but the ammonia level did not change with same treatment. In isokinetic knee joint test at the angular velocity of $60^{\circ}/sec$, $180^{\circ}/sec$, and $240^{\circ}/sec$ the taping treatment did not affect to any selected muscle EMG activities except maximal EMG of vastus lateralis at $240^{\circ}/sec$.
