effect of finger tip contact on the electromyography activity of ankle muscles

To investigate the effect of the light touch, vision and dual task interference on the surface electromyography [sEMG] activity of ankle muscles. Thirty right handed healthy persons stood in an upright and semi-tandem position and pressed the sensor plate in a rate less than 50 gr. sEMG activity was measured in three muscles [Tibialis Anterior, Proneus Longuse and Soleuse on both lower limbs by Biometrics sEMG]. Four positions were considered in semi-tandem standing i.e.: 1] No Touch, No Counting; 2] No Touch, Counting; 3] Light Touch, No Counting; 4] Light Touch, Counting. Each of the above positions was tested in two positions by means of Eyes Open, Eyes Closed. sEMG activity of the ankle muscles was lower in the light touch contact [LTC] [P<0.05], but higher during no-counting than counting [P<0.05]. LTC and the concentration on counting, stimulate the Central Nervous System for activating the postural muscles of hip and trunk. So the amount of imposed force on ankle muscles will be reduced

[ importance of phase I cardiac rehabilitation and evaluation of its performance in Tehran city Hospitals]

Few studies related to the importance of inpatient phase of cardiac rehabilitation and the percentage and full execution of phase I during admission have focused on its importance. The main goal of this study is evaluation and discussion about the importance and correct execution of phase I cardiac rehabilitation in Tehran city hospitals. Eleven hospitals among the governmental and nongovernmental ones which have cardiac surgery sections were chosen randomly. To gain the main purpose of study, we used a questionnaire that was prepared according to American Association of Cardiovascular and Pulmonary Rehabilitation [AACVPR] guideline. The questionnaires were sent to the heads of the cardiac rehabilitation departments by educated personnel in a two weeks period. These forms contained ten specialized questions with different scores about evaluation of the quality of phase I cardiac rehabilitation performance and attention to it. The scores were used in SPSS software to analysis the data. The results showed that only 10
