The Relationship Between the Joint Angle for Maximum Muscle Strength and VelocitySatoshi MIYASHITA1998 Volume 35 Issue 4 Pages 223-229

JOURNAL FREE ACCESSA peak torque was generally measured with an isokinetic machine to evaluate muscle strength. Recently, it has been pointed out that muscle strength does not necessarily correlate with the tolerance for muscle injury, and new concept for the measurement of the muscle strength with an isokinetic machine has been required. In this report the relation between the joint angle for the maximum muscle strength and the velocity is introduced to assess the maximum muscle strength output. The maximum muscle strength was measured with a Biodex multijoint system 2AP for 28 active sportsmen, 10 males (26.7±3.9 years old) and 18 females (20.1±2.8 years old). The maximum muscle strength output was developed for both sexes with satisfying a significant correlation between the joint angle and the velocity. These observations indicating the appearance of the optimal joint angle and velocity for the maximum muscle strength output offer a new method for the evaluation of the maximum muscle strength output.View full abstractDownload PDF (975K) -

JOURNAL FREE ACCESSAlthough swimming is known to be a useful treatment for low back pain, few studies have systematically examined the effectiveness of a variety of water exercises for the treatment of chronic low back pain. In this study, a series of exercises in water was carried out for 6 months by a group of 10 women suffering from chronic low back pain, and the effect was evaluated by periodic physical and spinal tests. The underwater exercises consisted of stretching and muscle strengthening exercises, and swimming using the crawl and backstroke. The women performed the exercises for 1 hour twice each week. Over the course of the study, low back pain was relieved in all patients. Furthermore, vital capacity increased and percent body fat decreased significantly. A remarkable improvement was shown by the spinal functional test (modified Kraus-Weber) and JOA scores. The results of this study indicate that underwater exercise is very effective for the treatment of chronic low back pain and physical strengthening.View full abstractDownload PDF (1145K) -
The Effect of the Size of a Set Joint Angle and Knee Motion on the Results of the Two Different TestsHiroyuki HIRANO, Toshimichi SUGIHARA1998 Volume 35 Issue 4 Pages 236-240

JOURNAL FREE ACCESSWe made a comparative study of the two different measurements of knee joint proprioception. The uninjured human knee was used as a model. Twenty volunteer's average age was 19.5 years. We measured knee joint angle using the electric goniometer. The reproduction of a set joint angle test and the matching of a set joint angle test were achieved by using active and passive range of motion for three preset joint angles. The set joint angles were 15°, 45° and 75°. The results showed that the normal value of two methods of measurement were not always comparable when the size of a set joint angle and knee motion arranged inadequately. However, the reproduced angle and matched angle are comparable when these test were achieved by using passive range of motion. When the set joint angle is 15° or 45°, the constant errors are comparable. The constant errors are comparable when the set joint angle was 15° or 45°, besides the knee joint motion was matched. On condition that the set joint and knee motion were optimized like above, we can consider these two different methods to be comparable.View full abstractDownload PDF (868K) -

JOURNAL FREE ACCESSThe object of this research was to study how to detect most effectively electromyogram (EMG) of suprahyoid muscles during swallowing. The position of recording electrodes on suprahyoid muscles during deglutition has been investigated in 6 healthy men. The EMG of suprahyoid muscles was detected by 4 methods designated as submental, submaxillary, lateral and hyoidal recording at full bite, tongue elevation in 2 seconds and water 3ml swallowing. The EMG area recorded by each method was divided by recording time (ms) and by inter-electrode distance (3-10cm). This parameter was called area/cm (μV·s/cm). The area/cm from the submental recording was about twice that from the other 3 methods at tongue elevation and water swallowing. It was concluded that the submental recording could detect the EMG of suprahyoid muscles most effectively and this method might be applicable to a biofeedback training in the rehabilitation for swallowing disorders.View full abstractDownload PDF (1089K) -
A Postsurgical Case of Oral Floor CancerYuji KOYAMA, Shin-ichi IZUMI, Akira ISHIDA, Kazuo SAKAIZUMI, Atsuo KAN ...1998 Volume 35 Issue 4 Pages 245-248

JOURNAL FREE ACCESSWe experienced a postsurgical patient with oral floor cancer and impaired tongue function who presented with a swallowing disorder of the oral preparatory and oral propulsive stages. To decrease dead space in the oral cavity, we made an intraoral reshaping prosthesis for the palate and floor. After placing the prosthesis, videofluorographic studies demonstrated an improvement in the propulsion of a bolus of jelly from the oral cavity into the pharynx. However, the patient could neither propel the jelly to the molar region with the tongue nor crush the jelly between the tongue and the hard palate. To facilitate compensatory masticatication in the front teeth region, we adjusted the form of the prosthesis. Results suggested that this prosthesis is effective for treating swallowing disorders of the oral propulsive stage.View full abstractDownload PDF (1734K) -

JOURNAL FREE ACCESSThis case report describes establishing the restorative rehabilitation goal for a 71-year-old female suffering from primary malignant lymphoma of the thoracic spine and radiation myelopathy who had previously received only palliative therapy. Primary malignant lymphoma of bone origin is very rare and has a survival rate of 58% at 5 years after onset with little mortality thereafter, based upon the data of 174 patients at Mayo Clinic. In 1991 she had back pain and gait disturbance which improved after treatment with surgery, radiation and chemotherapy in that year. She developed complete paraplegia due to radiation myelopathy, and had been almost totally dependent in ADL's at a hospice until admission to our rehabilitation hospital in 1996. The primary goal was independence in ADL using a wheelchair. We felt this was possible based on her physical condition, laboratory examination including bone scintigram, and her expected long term prognosis based on studies in the literature. Therefore we shifted the program from palliative rehabilitation to restorative. Eventually she became independent in activities of transfer and self-catheterization, and changed her attitude to be much more positive. In cancer rehabilitation, it is important to plan the program based on the prognosis of the disease as well as the patient's physical condition.View full abstractDownload PDF (1735K) -
