This study's aim was to evaluate the characteristics of newborn and young infants' spontaneous lower extremity movements by using dynamical systems analysis. Participants were 8 healthy full-term newborn infants (3 boys, 5 girls, mean birth weight and gestational age were 3070.6 g and 39 weeks). A tri-axial accelerometer measured limb movement acceleration(More)
[Purpose] This study aimed to clarify the effects of therapeutic ultrasound on range of motion and stretch pain and the relationships between the effects. [Subjects] The subjects were 15 healthy males. [Methods] Subjects performed all three interventions: (1) ultrasound (US group), (2) without powered ultrasound (placebo group), and (3) rest (control(More)
The aim of this study was to evaluate the characteristics of development of spontaneous movements in infants using dynamical systems analysis. The participants were 7 healthy, full-term, newborn infants. A tri-axial accelerometer was used to measure limb acceleration in three-dimensional space. Acceleration signals were recorded on the right wrist, when the(More)
[Purpose] This study aimed to clarify the immediate effects of a combined transcutaneous electrical nerve stimulation and stretching protocol. [Subjects] Fifteen healthy young males volunteered to participate in this study. The inclusion criterion was a straight leg raising range of motion of less than 70 degrees. [Methods] Subjects performed two protocols:(More)
The liver is one of the major target organs affected in sepsis that are usually accompanied with free radical formation. The use of minus charge for the prevention and cure of various radical related diseases is gaining wide importance in the medicinal field. Here, we investigate whether minus charge stimulation (MCS) inhibits nitric oxide (NO) production(More)
OBJECTIVE To investigate the influence of dentures wearing on the parameters of physical fitness, particularly on agility and balance function in elderly people. DESIGN A case control study. SETTING Motohachiohjimachi, Hachiohji, Tokyo, Japan. METHODS Motor reaction time was measured in the presence and absence of dentures in the subjects who were 1)(More)
PURPOSE This study aimed to clarify the effects of therapeutic ultrasound on intramuscular local blood circulation (and oxygen dynamics) using near-infrared spectroscopy (NIRS). PARTICIPANTS The participants were 11 healthy males. METHODS All participants performed all three trials; (1) the ultrasound (US group), (2) without powered ultrasound (placebo(More)
PURPOSES It has been reported that the amount of posterior tilt and upward rotation in scapular motions decreases with aging. The purposes of the current study were to investigate age related scapular motion regression and scapular restriction in patients with idiopathic frozen shoulder (IFS). METHODS The groups were recruited as follows: two groups of 50(More)
