Background: The maintenance of postural control is a key component in dynamic physical activity, especially during muscle fatigue and against external forces. Despite many studies in this field, there is no consensus regarding the effects of plantar flexor muscles fatigue on postural control during different postural tasks.Objective: To evaluate the effects of plantar flexor muscles fatigue on ...

  Abstract   Background: Postural instability has been identified as a potential precursor of   falls in elderly subjects. Postural stability in quiet stance is commonly assessed with   center of pressure (COP) measures. The purpose of this study was to determine testretest reliability and minimal detectable change (MDC) for the center of pressure   (COP) measures in the elderly subjects.   Met...

Background: Due to the importance of sleep in brain development of infants, this study was designed to compare the effects of environmental and behavioral Interventions on sleep cycle of preterm infants in NICU. Methods: In this prospective crossover clinical trial, 40 preterm infants with fetal age of 32 to 36 weeks hospitalized in NICU were selected. Infants...
