The present study examined whether the elderly produced a hastened or delayed tap with a negative or positive constant intertap interval error more frequently in self-paced tapping than in the stimulus-synchronized tapping for the 2 N target force at 2 or 4 Hz frequency. The analysis showed that, at both frequencies, the percentage of the delayed tap was larger in the self-paced tapping than in...

background: hypertension is one of the prevalent and dangerous complications of diabetes mellitus. as it is difficult to control hypertension, the necessity of using new techniques such as non-pharmaceutical methods and complementary therapy is doubled. this study aimed to determine the effect of aerobic exercise on the blood pressure of patients with type 2 diabetes. methods: this study was a ...

background: prevention of slipping accidents requires provision of adequate friction through the use of suitable combinations of footwear and underfoot surfaces. shoe sole tread groove is one of the important factors on friction coefficient during walking. objective: to measure the effect of different shoe sole tread groove depths and different surfaces on the required quotient of friction (q),...

Background: There is considerable evidence that repetitive transcranial magnetic stimulation (rTMS) of motor cortex exerts significant improvement of motor performance in parkinson's disease (PD) patients in previous studies. Other authors have used brain imaging to show that single session rTMS can transiently increase DA in striatum. Here we try to evaluate whether the rTMS in our study could...

Interference between concurrent tasks was used to investigate the brain basis of capacity limitations apparent when children encode information. Seventy-three right-handed children in Grades 1-4 engaged in speeded unilateral finger tapping while encoding a variable number of faces or numbers for subsequent recognition testing. With both face and number encoding, tapping rate decreased as memory...
