Lower trunk muscle activity-induced alignment and cop position during single-leg standing.

[Purpose] The purpose of this study was to clarify fundamental changes induced by lower trunk muscle contraction during single-leg standing. [Subjects and Methods] Ten healthy normal males participated in this study. All subjects could accurately perform lower trunk muscle contraction-type Abdominal Expansion (AE), Abdominal Bracing (AB), and Abdominal Cave-in (AC).

Effect of magnetotherapeutic device on pain associated with neck and shoulder stiffness.

To examine the effectiveness of a neck-type magnetotherapeutic device (MTD), we performed a study of neck and shoulder pain or stiffness measured with a visual analog scale (VAS) and objective parameters (thermography, deep body thermometry, and a muscle meter). There were 62 patients (29 men and 33 women; mean age, 34 y; range, 21 to 58 y) in the study. The patients were randomly assigned (double-blinded) to receive treatment with the MTD or non-MTD.

Efficacy of static magnetic field for locomotor activity of experimental osteopenia.

In order to examine the effectiveness of applying a static magnetic field (SMF) for increasing bone mineral density (BMD), we assessed the degree of osteopenia by dual-energy X-ray absorptiometry (DEXA), the metabolism measuring system, and histological examination of bone tissue in an ovariectomized (OVX) rat model. Thirty-six female Wistar rats (8 weeks old, 160-180 g) were divided into three groups. The rats in the OVX-M group were exposed to SMF for 12 weeks after ovariectomy.

Effect of kami-kihi-to (jia-wei-gui-pi-tang) for experimental osteopenia.

In order to examine the effects of Kami-kihi-to (KKT or Jia-Wei-Gui-Pi-Tang) on osteopenia, we measured bone mineral density using computed X-ray absorptometry and monitored metabolism and bone tissue in an ovariectomized (OVX) rat model. Bone mineral density was significantly lower in the OVX group than in normal group 3 months after ovariectomy. However, the bone mineral density of the OVX group administered KKT was clearly higher than that of the untreated OVX group.

Study on Application of Static Magnetic Field for Adjuvant Arthritis Rats.

In order to examine the effectiveness of the application of static magnetic field (SMF) on pain relief, we performed a study on rats with adjuvant arthritis (AA). Sixty female Sprague-Dawley (SD) rats (age: 6 weeks, body weight: approximately 160 g) were divided into three groups [SMF-treated AA rats (Group I), non-SMF-treated AA rats (Group II) and control rats (Group III)]. The SD rats were injected in the left hind leg with 0.

Study of sokei-kakketu-to (shu-jing-huo-xue-tang) in adjuvant arthritis rats.

To examine the effectiveness of the herbal medicine prescription, Shu-Jing-Huo-Xue-Tang (SJHXT), for pain relief, we performed a study using rats with adjuvant arthritis (AA). After injecting the adjuvant, AA rats were maintained for 6 months as a chronic pain model. Starting at 6 months, SJHXT was administered for 12 weeks.
