background: osteoporosis is one of the most common metabolic bone diseases. the purpose of this study was to investigate the effect of a prevention program based on health belief model on osteoporosis among women. methods: in this quasi-case study, 120 patients (60 cases and 60 control), registered under the health centers in fasa city, fars province, iran were selected in 2014. a questionnaire...

objectives: the purpose of current semi-experimental study was a survey on effect abstract  of 16 week walking on psychosocial functioning related to quality of life among 60 to 75 years old men. methods & materials: for this reason, short form of health-related quality of life questionnaire (sf-36) and geriatric depression scale (gds) had been distributed to the subjects at 2 times of pre-test...

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 ...

Visual flow is used to perceive and regulate movement speed during locomotion. We assessed the extent to which variation in flow from the ground plane, arising from static visual textures, influences locomotion speed under conditions of concurrent perceptual load. In two experiments, participants walked over a 12-m projected walkway that consisted of stripes that were oriented orthogonal to the...

dynamically stable biped robots mimicking human locomotion have received significant attention over the last few decades. formerly, the existence of stable periodic gaits for straight walking of passive biped walkers was well known and investigated as the notion of passive dynamic walking. this study is aimed to elaborate this notion in the case of three dimensional (3d) walking and extend it f...

this paper proposes a gait planning approach to reduce the required friction for a biped robot walking on various surfaces. to this end, a humanoid robot with 18 dof is considered to develop a dynamics model for studying various 3d manoeuvres. then, feasible trajectories are developed to alleviate the fluctuations on the upper body to resemble human-like walking. in order to generate feasible w...
