Effects of infant care posture and weight on static postural balance.

Background: Studies investigating postural balance during various infant care postures have not been reported yet.

Objective: The aim of this study was to measure static postural balance when holding an infant dummy in-arms and carrying an infant dummy on back according to different infant dummy weights.

Methods: Sixteen healthy young subjects participated in a balance test.

Comparison of resting tremor at the upper limb joints between patients with Parkinson's disease and scans without evidence of dopaminergic deficit.

Background: A representative symptom of Parkinson's disease (PD) is resting tremor. The clinical manifestation of scans without evidence of dopaminergic deficit (SWEDD) is similar to it of PD, though the phenomenology of SWEDD is not well known.

Objective: In the present study, the resting tremor of 9 SWEDD patients was quantitatively compared with that of 11 PD patients.

Protective effects of against cognitive impairment by regulating oxidative stress in an amyloid beta-induced Alzheimer's disease mouse model.

Background/objectives: Alzheimer's disease (AD) is one of the most representative neurodegenerative disease mainly caused by the excessive production of amyloid beta (Aβ). Several studies on the antioxidant activity and protective effects of (PT) against cerebral ischemia-induced neuronal damage have been reported. Based on this background, the present study investigated the protective effects of PT against cognitive impairment in AD.

Analysis of maximum joint moment during infant lifting-up motion.

Background: Infant care activities can induce musculoskeletal disease. However, little is known about the biomechanical joint load during lifting-up of an infant.

Objective: The aim of this study was to investigate normalized maximum moment during lifting-up of infant dummies weighing 4.

Age-related differences in the quantitative analysis of the finger tapping task.

Background: Quantitative measures of the finger tapping task is important for objective assessment of bradykinesia. However, age-related changes in quantitative measures are still unclear.

Objective: The aim of this study was to quantitatively investigate age-related group differences in finger tapping performance.

Protective effects of krill oil on high fat diet-induced cognitive impairment by regulation of oxidative stress.

Consumption of high fat diet (HFD) increases risk of cognitive impairment and memory deficit by elevation of oxidative stress in the brain. In this study, we investigated the protective effects of krill oil (KO) against HFD-induced cognitive impairment in mice. The mice were fed with HFD for 10 weeks, and then KO was orally administered at doses of 100, 200, or 500 mg/kg/d for 4 weeks.

Quantitative measures of postural tremor at the upper limb joints in patients with essential tremor.

Background: It is important to quantitatively assess tremor for accurate diagnosis and evaluation of the response to interventions in patients with essential tremor (ET).

Objective: The purpose of this study was to investigate the relationship between quantitative measures of postural tremor and clinical rating scale in patients with ET.

Methods: 18 ET patients performed a postural tremor task that required them to hold their arms outstretched parallel to the floor while wearing a gyro sensor based measurement system.

The Association between 10-Year Atherosclerotic Cardiovascular Diseases Risk Score Calculated Using 2013 American College of Cardiology/American Heart Association Guidelines and Serum 25-Hydroxyvitamin D Level among Aged 40-79 Years in Korea: The Sixth Korea National Health and Nutrition Examination Surveys.

Background: We examined the relationship between 10-year predicted atherosclerosis cardiovascular disease (ASCVD) risk score and 25-hydroxyvitamin D in Koreans aged 40-79 years.

Methods: A population-based, cross-sectional design was used from data based on the Korea National Health and Nutrition Examination Survey 2014.

Results: A total of 1,134 healthy Koreans aged 40-79 years were included.

Comparison of gait patterns in elderly fallers and non-fallers.

Gait is associated with an important risk factor of falls in the elderly. It is important to find differences of quantitative gait variables between fallers and non-fallers. The aim of this study was to investigate gait patterns in elderly fallers and non-fallers.

Differences in activities of the lower extremity muscles with and without heel contact during stair ascent by young women wearing high-heeled shoes.

Background: The purpose of this study was to identify any differences in the activity patterns of lower extremity muscles with and without heel contact during stair ascent by women in their twenties wearing high-heeled shoes.

Methods: Twenty healthy female subjects wearing high-heeled shoes walked up a step with a height of 20 cm with and without heel contact, during which the activities of the vastus medialis oblique, vastus lateralis, and gastrocnemius were recorded using surface electromyography.

Results: During stair ascent the activities of the vastus lateralis and vastus medialis oblique were significantly higher and that of the gastrocnemius significantly lower with high-heel contact than without high-heel contact.
